ABSTRACT
Abstract Dietary habits of bandicoot rats (bandicota bengalensis) were investigated in the agricultural crops of the Pothwar Plateau, Pakistan by analysing stomach contents. The research activities were conducted in major field crops including wheat-groundnut and in the fallow lands during non-crop season at the field boundaries. The specimens were captured from the fields using kill/snap traps, and dissected to collect their stomach samples for laboratory analysis. Light microscopic slides of the plant material were recovered from stomach samples and the reference materials were collected from the field. Results revealed that the bandicoot rat predominantly fed upon cultivated crops during cropping season but consumed wild vegetation during non-cropping season. There was no significance difference between summer and winter diets. Most frequently consumed crop food items were wheat (Triticum aestivum; 28.57%), groundnut (Arachis hypogea; 11.26%), sorghum (Sorghum bicolor; 10.17%), chickpea (Cicer arietinum; 9.52%), maize (Zea mays; 6.49%), millet (Pennisetum glaucum; 5.84%), barley (Hordeum vulgare; 4.98%) and mustard (Brassica campestris; 4.98%). Among wild vegetation were consumed khbal gha (Cynodon dactylon; 7.79%), baron dhab (Demostachya bipinnata; 7.36%) and Prickly flower (Achyranthes aspera; 3.03%). The study concludes that, in addition to consuming wheat and groundnut crops, the Lesser bandicoot rat also subsists on grasses, weeds, and some fodder crops, as important component of its diet in agro-ecosystem of the Pothwar Plateau.

ABSTRACT
Aims: To refine nutrient management practices for the groundnut-blackgram cropping sequence, focusing on enhancing both yield and quality.Study Design: The experiment was conducted in a split-plot design with three replications.Place and Duration of Study: Regional Research Station in Vridhachalam during the Kharif and rabi season of 2016-17.Methodology: The experimental encompassed various nutrient levels applied to groundnut in the main plots: M1-Control, M2-100% RDF, M3-125% RDF, and M4-150% RDF. Additionally, different nutrient levels were applied to the blackgram subplot: S1-Control, S2-50% RDF, S3-75% RDF, and S4-100% RDF.Results: Analysis of the results indicated that use of 125% RDF in groundnut significantly provide higher pod yield (2657 kg/ha). However, the control group recorded a significantly lower pod yield. Subsequent blackgram seed yield was notably influenced by inorganic fertilizers applied to the preceding groundnut crop. In blackgram, the application of 75% RDF resulted in a higher number of pods per plant (34.6), No. of branches/plant (7.8) and seed yield (823 kg/ha). This performance was comparable to the application of 100% RDFConclusion: These findings underscore the importance of optimizing nutrient management practices, particularly the combination of 125% RDF for groundnut, to enhance pod yield, while the application of 75% RDF demonstrated positive effects on subsequent blackgram seed yield.
ABSTRACT
Optimizing mineral nutrition is crucial to boosting groundnut output since groundnut have a high nutritional requirement and the recently released high yielding varieties further absorb nutrients from the soil. On the other hand, farmers that grow groundnut sometimes employ only one or two nutrient-rich fertilizers, which results in severe mineral deficits. One of the primary reasons for low groundnut productivity is inadequate and imbalanced nutrient usage. At the Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra, India, a field experiment was carried out in the summer to assess the effects of organic, inorganic, and foliar grade fertilizers on the growth and yield of groundnut. The integration of organic, inorganic, and foliar grade fertilizers considerably improves growth and yield qualities, according to experimental data. The findings showed that the application of FYM @ 7.5 t ha-1+100% RDF 25:75:25 NPK kg ha-1 considerably improved plant growth parameters, such as plant height and yield attributes yield. Starter dose (11:36:24 NPK + trace element) + booster dose (8:16:39 NPK + trace elements) applied topically. It was determined that integration of organic (7.5 t ha-1), inorganic fertilizer (100% RDF), and water soluble grade fertilizer recorded, highest dry pods yield and getting maximum economic return from summer groundnut. This treatment was closely followed by treatment FYM @ 7.5 t ha-1+100 % RDNPK, which recorded significant pod yield (27.18 qt ha-1), net monetary return (79464 Rs. ha-1) and benefit: cost ratio (2.77).
ABSTRACT
The present investigation entitled “Effect of Water Stress and Paclobutrazole on Proline and Total Antioxidant Activity in Groundnut (Arachis hypogaea L.)” was carried out during during the summer seasons of the year 2021 and 2022. Twelve treatments comprising of all possible combinations of three irrigation levels for water stress and four paclobutrazole (PBZ) levels were tested in a split plot design with three replications. Total antioxidant activity and proline content showed significantly higher with irrigation at 20 days interval. Whereas, minimum was recorded with irrigation at 10 days interval in pooled results. The significantly higher total antioxidant activity and proline content was recorded with application of PBZ @ 300 mg/ L during both the years and in pooled analysis, respectively, whereas a minimum was noted with control (No spray of PBZ).
ABSTRACT
A study was carried out in Teaching and Research Farm of Delta State, Abraka in 2022 and repeated in 2023 farming seasons to assess the impact of variety and variable rates of cow dung on growth characters of groundnut in Abraka, Nigeria. It was a 2 x 5 factorial experiment in randomized complete block design with three replications. Seven parameters were investigated to achieve the objectives of the study, including initial soil physico-chemical properties of the experimental site before planting, percentage emergence of the varieties after 10 days of planting based on different rates of cow dung applied, plant height, number of branches per stand, number of leaves per stand, leaf area and chemical properties of the cow dung used for the study. The results of the study showed that Samnut-21 was superior in all the parameters assessed, while manure application rate of 20 tha-1 was outstanding in performance of the growth characters. It was therefore recommended that farmers in the study area adopt Samnut-21 and 20 tha-1 of cow dung for groundnut production in Abraka, Delta State, Nigeria.
ABSTRACT
A field study on “Assessing Groundnut (Arachis hypogaea L.) genotype yields and yield traits with different planting geometries on broad bed and furrows” was conducted during rabi season of 2022 in the experimental field at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Hyderabad, Telangana. The experiment was laid out in factorial randomised block design with three replications. Total 16 treatment combinations consisted of four planting geometries (P1) 30 × 10 cm, (P2) 15:15 × 10 cm, (P3) 20:20 × 10 cm, (P4) 25:25 × 10 cm and four varieties (V1) Girnar 4, (V2) Girnar 5, (V3) Avtar, (V4) K6. The important findings emerged from this investigation found that groundnut sown at the spacing of (P4) 25:25 × 10 cm recorded significantly higher number of pods plant-1 (33.0), kernels pod-1 (2.0), test weight (38.7 g), shelling percentage (67.1%), pod yield (1792 kg ha-1) followed by (P3) 20:20 × 10 cm, (P4) 30 × 10 cm and (P2) 15:15 × 10 cm. The genotype V2 (Girnar 5) performed best in yield and yield contributing characteristics than other genotypes and it was on par with V1 (Girnar 4). Hence, our results concluded that (P4) 25:25 × 10 cm spacing, performing best with (V2) Girnar 5 and (V1) Girnar 4 varieties.
ABSTRACT
The cluster frontline demonstrations (CFLDs) on groundnut were conducted by ICAR- Krishi Vigyan Kendra, Virinjipuram, Vellore District (Tamil Nadu) during Rabi season from 2020-2021 and 2021-2022 farmer’s field of different villages of Vellore district. The results revealed that the average higher pod (25.18 q/ha.) were recorded in CFLDs as compared to farmer’s practices (FP) average pod (16.50 q/ha). The increase in the demonstrations pod yield over FP was 48.81 %. The extension gap, technology gap and technology index were 8.68 q/ha., 1.93 q/ha. and 6.76 % respectively. The average gross return (Rs. 100920/ha.) and net return (Rs. 66677/ha.) in CFLDs were found higher than the FP gross return (Rs. 65700/ha.) and net return (Rs. 31130/ha.). The B: C ratio exhibited the same trend as in gross and net return which was found 2.95 in CFLDs and 1.90 in Farmer practice. By conducting cluster frontline demonstrations of improved variety with intervention practices of proven technologies in farmer’s field, yield and increased the doubling income with higher productivity in Groundnut.
ABSTRACT
Diverse groundnut parents were used to generate 36 advanced breeding lines to develop into a confectionery genotype for yield, quality, and main biotic stress. Groundnut use is increasing in both food and confectionary due to the steady change in groundnut consumption patterns. Advanced breeding lines evaluated in randomized complete block design including parents and checks during kharif and summer, 2021 respectively. High genetic variability (%) and heritability (%) observed for hundred seed weight (21.08 & 86.34), pod yield per plant (25.37 & 87.66), pod yield (31.63 & 83.71), late leaf spot (32.71 & 79.16), rust disease (39.86 & 87.06), oil content (2.55 & 79.60), Blanchability (18.76 & 97.00), oleic acid (8.52 & 72.90), linoleic acid (16.32 & 73.40) and O/L ratio (24.64 & 73.60) respectively. The correlation between hundred seed weight, sound mature kernels, shelling percentage and pod yield per plant with kernel yield showed positive association. Rust and LLS disease revealed a high positive connection indicating that an increase in late leaf spot disease incidence enhances the incidence of rust disease and vice versa in groundnut. Substantial negative association was found between two crucial quality parameters such as oil content and protein content, as these two characteristics determine the quality of groundnut for confectionary purposes. Path analysis indicates kernel yield had the greatest direct positive effect on pod yield, followed by seed weight, oil content and sound mature kernel and direct selection for these characteristics would be effective. The path analysis of quality attributes revealed that at the genotypic level, oil content, protein content, and O/L ratio have the most direct effect on hundred seed weight.
ABSTRACT
Late Leaf Spot (LLS) disease is caused by Phaeoisariopsis personata, a devastating disease that significantly affects groundnut (Arachis hypogaea L.) production worldwide. This research aimed to investigate the disease progress in resistant and susceptible groundnut genotypes under green house conditions with artificial inoculations. The four popularly growing groundnut cultivars in Andhra Pradesh i.e., Kadiri-6 (K6), Dharani, Harithandra and Lepakshi (K-1812) were evaluated in this study. The disease severity scale, percent disease index (PDI), Area under disease progression curve (AUDPC) and the epidemic rate (rate) were estimated by using the linear model. Highest disease severity was observed in K6 (88.19 %) and Dharani (85.19 %) with greater disease progression rate was observed in K6 (0.13) and Dharani (0.12) cultivars. However, the lowest disease progression was observed in Lepakshi (0.04) and Harithandhra (0.08) cultivars. Enhanced resistance to LLS was reported with Harithandhra and Lepakshi cultivars due to slower epidemic rate, longer incubation and latent periods with smaller lesions.

ABSTRACT
The aim of the study is to identify the suitable modified atmospheric storage condition required for long term storage of groundnut (Arachis hypogaea L.) variety TMV (Gn) 13. The experiment was conducted during 2022 at Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore. The groundnut pods and kernels were subjected into different storage conditions viz., pods stored in gunny bag, kernels stored in gunny bag, kernels stored in polythene bag, kernels stored with N?gas and kernels stored in vacuum conditions. The results revealed that pod storage recorded the maximum germination percentage (73%), root length (14.5cm), shoot length(14.3cm), dry matter production (3.47 g 10 seedlings -1) and vigour (2136). Similarly, enzymes viz., dehydrogenase( 0.72 OD value), peroxidise (1.29U mg?¹ protein min?¹), alpha amylase (13.60mg maltose min-1) and catalase activity (1.253 µmolH?O? min?¹g?¹ protein) were also maximum in pod storage with minimum harmful effect of pest(0.6%) and fungus incidence(17%). The nitrogen storage conditions also have maximum enzyme activity viz., dehydrogenase (0.64 OD value), peroxidise (1.24U mg?¹ protein min?¹), alpha amylase (13.58 mg maltose min-1) and catalase activity (1.220 µmolH?O? min?¹g?¹ protein) with minimum harmful effect of pest (0.6%) and fungus incidence (20%). Present study, it is concluded that groundnut kernels stored under modified atmospheric storage i.e. nitrogen gas storage can maintain the seed longevity by minimizing the deterioration process in groundnut equally as that of pod storage. Further, it will helps to minimize the expenditure towards transport and storage.
ABSTRACT
The roving survey on the incidence of pests and diseases in groundnut and castor was conducted from August, 2020 to March 2021 in Salem district at fortnight intervals revealed that, in groundnut , leaffolder (20.38%), cutworms S. litura (1.63/20 pls), thrips (10.69/20 pls), leaf spot (15.25%) and root rot (6.31%) , similarly in castor pests, whiteflies (23.06/20 pls), A. janata (8.38/20 pls), S. litura (10.19/ 20 pls), thrips (11.63 / 20 pls), C. punctiferalis (7.25/20 pls), alternaria blight (17.56%) and botrytis rot (4.19%) were found feeding /infecting on different parts of the crops. The correlation with weather parameters indicated, positive correlation of rainfall, relative humidity and wind speed on incidence of leaffolder (0.47998, 0.311421 and 0.339961) but rainfall and relative humidity increased root rot (0.433059 and 0.393255) whereas, maximum temperature influenced high infection of leafspot (0.67911) in groundnut. The whiteflies incidence in castor was positively correlated with (0.490967) and rainfall (0.389125) whereas, lepidopteran pests by relative humidity (0.61212) and rainfall (0.49415). The thrips and botrytis rot were influenced by relative humidity and rainfall rot (0.65914 and 0.77965, 0.57456 and 0.82709). But natural enemies in groundnut and castor had non-significant correlation with weather parameters.
ABSTRACT
Silver nanoparticle (AgNPs) is one of the widely used nanoparticles because of their antimicrobial properties. In this present study, the effect of green synthesized silver nanoparticles and bulk form of silver (AgNO3) at different concentrations (250, 500, 750 and 1000 ppm) on seed quality parameters of groundnut were studied. Silver nanoparticles synthesized using Azadirachta indica leaves were characterized by Dynamic light scattering, UV- Vis and FTIR spectrum. Size, zeta potential, UV- Vis absorbance peak and FTIR spectrum of the AgNPs measured 28.6 nm, 24.6 mV, 350 to 490 nm and 3334.53 cm-1 respectively. The results showed that AgNPs 1000 ppm was found best in enhancing the seed quality parameters such as germination percentage, root length, shoot length, seedling length, root dry weight, shoot dry weight, seedling dry weight, seed vigour index I& II.
ABSTRACT
Four genotypes of groundnut (Arachis hypogaea L.) viz., K-6, Naryani, Darani and K-9 were raised under Free Air Temperature Elevated (FATE) condition. The plants were raised in open rings with elevated temperature (+3°C) and carbon dioxide (550ppm) during rabi 2016 to investigate the effect of increased temperature and its interaction with CO2 on various seed quality parameters. The physiological parameters decreased under elevated CO2 and temperature. The results revealed that germination ranged from 81.5 to 90 per cent between four genotypes i.e., K-6, Naryani, Darani and K-9. Similarly speed of germination 49 to 83.02, shoot length 14.73 to 7.70, root length ranges from 20.80 to 9.50, and seedling vigour index 123.47 to 98.53 and seedling dry weight 0.919 to 0.100 g. Further, biochemical parameters like SOD, MDA and ? amylase content increased at eT + eCO2 as compared to control treatment. Limited evidence suggests that only short periods of high-temperature stress at critical seed development stages are required to reduce seed vigour, but further research is required. The predicted environmental changes will lead to losses of seed quality particularly for seed vigour and possibly germination.The present study shows that temperature impacts the groundnut crop’s physiological and quality parameters.

ABSTRACT
This study addresses a knowledge gap in understanding the interaction effect of nutrient-plant growth regulators on groundnut which plays a vital role in morpho-physiological processes for achieving enhanced productivity. The main goal was to evaluate how different nutrio-hormonal combinations affect groundnut traits. The experiment was conducted in pot culture at glasshouse, Department of Crop Physiology, TNAU, Coimbatore, utilizing a factorial completely randomized design. Two genotypes, BSR 2 and VRI 8, received five treatments with four replications: T1 - control (foliar water spray), T2 - Nutrio hormonal consortia 1, T3 - Nutrio hormonal consortia 2 (T2 + K2SO4), T4 - Groundnut booster 1 (FeSO4, K2SO4, MgSO4, Borax), and T5 - Groundnut booster 2 (T4 + Salicylic acid + NAA-Naphthalene Acetic Acid). Application of T5 to VRI 8 showed significant results, with higher leaf area (2297.83 cm²) and specific leaf weight (19.87 mg/cm²) where as BSR 2 had smaller leaf area (872.86 cm²) and higher specific leaf weight (51.55 mg/cm²). VRI 8 had fewer pods but higher yield (8.16 g/plant) than BSR 2 (7.07 g/plant). In conclusion, the foliar application of T5 - Groundnut booster 2 with the VRI 8 variety holds promising potential for enhancing groundnut yield.

Experiment was laid out in Randomized Block Design (RBD) with 3 replicates of 10 treatments. The results showed that treatment 9 of [Ca (40kg/ha) + GA3 (120ppm)] recorded significantly higher plant height (60.4 cm), more dry weight (45.95g), maximum number of nodules/plant (16.4), maximum number of pods/plant (24.60), maximum number of kernels/pod (1.93), higher seed index (37.8 g), higher seed yield (2.02t/ha), higher haulm yield (4.11 t/ha) and higher harvest index (32.83 %). Maximum gross returns (1,25,778.00 INR/ha), maximum net returns (87,853.50 INR/ha) and highest benefit cost ratio (2.32) was also recorded in treatment 9 of Ca (40kg/ha) + GA3 (120ppm) as compared to other treatments.
