Effect of Integrated Nutrient Management Practices on Growth and Yield of Chickpea under Different Chickpea-Based Cropping Systems in Western Rajasthan, India

A field experiment was carried out during rabi season of 2020-21 in Pearl millet – Chickpea, Clusterbean + Sesamum (6:2) - Chickpea system to study the effect of nutrient management practices ((1.) Recommended fertilizers (100% RDF) (2.) 75% RDF + 5 t FYM (3.) 75% RDF + 5 t FYM + Biofertilizers (4.) 50% RDF + 5 t FYM + Biofertilizers + Crop residue) on crop growth, yield attributes and yield of chickpea. The results of the study revealed that the integration of 75% of the Recommended Dose of Fertilizers (RDF) with farmyard manure (FYM) and biofertilizers (BF) significantly enhanced chickpea growth and yield. This improved plant height, dry matter accumulation, branch number, and pod count, reflecting the synergistic effect of combining organic and inorganic inputs. This approach not only boosted the seed yield by 22.11% compared to the 75% RDF + 5t FYM but also matched the performance of the 100% RDF, offering a more sustainable cultivation strategy. These findings underscore the importance of adopting integrated nutrient management practices in chickpea cultivation, particularly in the arid region of western Rajasthan. Such practices have the potential to improve crop performance, increase yields, and promote sustainable agriculture in the area.

Similarly after validation the highest deviation percentage at anthesis days was (0 to 10.7%) for JG-16, at physiological maturity (1.8 to 3.6%) for Vaibhav and in seed yield (2.4 to 9.5%) for JG-16.

Effect of Different Weed Management Practices on Growth Characters of Chickpea in Mid-hills of Himachal Pradesh, India

Chickpea (Cicer arietinum) is one of the most important pulse legumes in many parts of the world. India is largest producer of chickpea in the world, sharing 65 and 70 % of the total global area and production, respectively. Different weed control practices use of herbicides were followed for better management. Application of herbicide at critical growth stages followed by one or two hand weeding at proper time or manipulation of row spacing for improving the weed suppressing effect of crops gives marginal improvement in crop yield. A field experiment titled “Effects of Different Weed Management Practices on Growth Characters of Chickpea in Mid-hills of Himachal Pradesh” was conducted during rabi season of 2022 at Chamelti Agriculture Farm, MS Swaminathan School of Agriculture, Shoolini University of Biotechnology and Management Sciences, Solan. The soil of the experimental field was sandy loam in texture, slightly alkaline in reaction with EC in a safer range, medium in organic carbon, available nitrogen, potassium, and high in available phosphorus. The experiment was laid out in randomized block design with three replications comprising ten weed management treatments viz. (T1) One hand weeding at 20 DAS, (T2) Two hand weeding at 20 and 40 DAS, (T3) Pendimethalin 30 EC @ 1.0 kg ha-1 (PE), (T4) Imazethapyr 10 SL @ 1.0 kg ha-1 (PoE) at 25 DAS, (T5) Pendimethalin 30 EC @ 1.0 kg ha-1 (PE) + One hand weeding at 30 DAS, (T6) Imazethapyr 10 SL @ 1.0 kg ha-1 (PoE) at 25 DAS + One hand weeding at 40 DAS, (T7) Fenoxaprop-p-ethyl 9.3 EC @ 60 g ha-1 (PoE) at 25 DAS + One hand weeding at 40 DAS, (T8) Pendimethalin 30 EC @ 1.0 kg ha-1 (PE) + Imazethapyr 10 SL @ 1.0 kg ha-1 (PoE) at 25 DAS, (T9) Weed free and (T10) Weedy Check. The recommended dose of fertilizer (30:60:30 kg ha-1) was applied through Urea, SSP, and MOP at the time of sowing. PBG-7 variety of chickpea was used for sowing. Weed management practices were done as per treatment. Other crop management practices were followed as per the recommendation of the area. Application of (T8) Pendimethalin 30 EC @ 1.0 kg ha-1 (PE) + Imazethapyr 10 SL @ 1.0 kg ha-1 (PoE) at 25 DAS registered higher growth parameters viz. plant height, number of branches plant-1, dry matter accumulation and crop growth rate. Thus, study suggest that chickpea can successfully grown under Mid-hills of Himachal Pradesh on (T8) Pendimethalin 30 EC @ 1.0 kg ha-1 (PE) + Imazethapyr 10 SL @ 1.0 kg ha-1 (PoE) at 25 DAS.

Evaluation of the Impact of Herbicidal Weed Management Practices on Weed Density, Yield Attributes and Yield of Irrigated Chickpea (Cicer arietinum L.)

In the Rabi season of 2021-22, an experiment was conducted at the Agronomy Research Farm of CCS Haryana Agricultural University in Hisar. The aim was to examine how herbicidal weed management affects irrigated chickpea. The experiment was laid out in Randomised Block Design (RBD) with thirteen treatments, each repeated three times. The treatments included various herbicides applied at different stages, such as pre-plant incorporation (PPI), pre-emergence (PRE), and post-emergence (POE). Interestingly, the Ready mix (RM) herbicide application of pendimethalin + imazethapyr (RM) @ 1000 g a.i ha-1, applied both as PPI and PRE, outperformed the herbicides applied solely as PPI, PRE, or POE. Among the herbicidal treatments, the combined during PPI and PRE stages exhibited excellent control over a diverse weed population, leading to a significant increase in chickpea yield compared to the weedy check. The number of seeds per pod, pods per plant, and branches per plant varied significantly with different weed control treatments. Weed-free plots showed the highest values in these parameters. The uncontrolled growth of weeds in the weedy check resulted in a 55.2% reduction in seed yield as compared to weed-free plots. The maximum seed yield (1968 kg ha-1) and favorable yield attributes were observed in the weed- free treatment, statistically comparable to the yield obtained from two hand weeding at 30 and 50 days after sowing (1940 kg ha-1). Among herbicidal treatments, the highest seed yield was achieved with the PRE application of pendimethalin + imazethapyr (RM) @ 1000 g a.i. ha-1 (1827 kg ha-1). The dominant weed flora consisted of Chenopodium album, Fumaria parviflora and Anagallis arvensis. Density of different weed species was significantly influenced by different weed control treatments. All the weed control treatments significantly reduced the total weed density and dry matter accumulation by weeds in comparison to weedy check. Weed free and two hand hoeing reduced the weed population drastically which was statistically at par with PRE application of pendimethalin + imazethapyr (RM) at 1000 g a.i. ha-1. Chenopodium album, Fumaria parviflora and Anagallis arvensis were effectively controlled by RM irrespective of its time of application.

Study of the Most Suitable Combination of Intercropping Systems of Indian Mustard (Brassica juncea L.) with Chickpea, Lentil, Linseed and Field Pea

Abstract: Intercropping system enhances crop productivity and profitability by growing different species together on the same piece of land in distinct row combinations. Hence, a field experiment was conducted to study the most suitable combination of mustard based intercropping with different crops at students’ instructional farm, C. S. Azad University of Agriculture & Technology, Kanpur (U.P.) during Rabi season 2021-22. The experiment was laid out in Randomized Block Design with nine treatment combinations viz., T1 Sole Mustard, T2 Mustard: Chickpea (1:1), T3 Mustard: Chickpea (2:1), T4 Mustard: Lentil (1:1), T5 Mustard: Lentil (2:1), T6 Mustard: Linseed (1:1), T7 Mustard: Linseed (2:1), T8 Mustard: Field Pea (1:1) and T9 Mustard: Field Pea (2:1) with replicated thrice. The results revealed that the significant impact of intercropping system on the growth, yield attributes, and overall yield of mustard when intercropped with chickpea, lentil, linseed, and pea. Plant population of intercrops showed non-significant differences, but at later stages, a 1:1 ratio consistently led to higher plant populations. Plant height, primary branches, and dry weight were generally higher in the 1:1 ratio compared to the 2:1 ratio in all intercrops. Yield attributes, including the number of pods or capsules and seeds per pod or capsule, favoured the 1:1 ratio. The highest yield was observed in the 1:1 ratio, contrasting with the minimum in the 2:1 ratio of mustard + intercrops. Overall, the 1:1 ratio demonstrated superior performance in terms of growth, yield attributes and yield, emphasizing the importance of intercrop ratio in optimizing crop growth and productivity.

Adoption of Recommended Package of Practices of Chickpea Varieties (JG-11 and JAKI 9218) in Dharwad District of Karnataka, India

Chickpea (Cicer arietinum L.) is mainly a rabi season crop of India grown in diverse agroclimatic conditions under various cropping systems and a major pulse crop in Karnataka state. JG-11 and JAKI-9218 are two prominent chickpea varieties cultivated by farmers in Dharwad district along with Annigeri-1 (local variety). The study throws light on profile characteristics and level of adoption of recommended package of practices of the above chickpea varieties. The study was conducted in Dharwad, Navalgund and Kundagol taluks of Dharwad district of Karnataka state during 2020-21 with a sample of 135 chickpea farmers. “Ex-post facto” research design was employed for the study. The data was elicited through personal interview method. Nearly half (48.89 %) of chickpea farmers belonged to low adoption category of recommended chickpea package of practices followed by medium (36.30 %) and high (14.81 %) categories. The probable reasons for low to medium adoption of recommended practices because majority of the farmers are not aware of the recommended package of practices and also farmers expressed disbelief towards the recommended package of practices because if they practice other methods, they have a fear of losing the yield.

Enhancing Nutrient Content and Uptake in Chickpea through Phosphorus and PSB Inoculation in Custard Apple Based Agri-horti System

The field experiment was conducted during the Rabi season of 2018-19 at the Agricultural Research Farm of Rajiv Gandhi South Campus, Banaras Hindu University, Barkachha, Mirzapur, Uttar Pradesh, India. This study aimed to investigate the effects of varying levels of phosphorus and inoculation with Phosphate Solubilizing Bacteria (PSB) on nutrient content and uptake in chickpea (Cicer arietinum L.) in a custard apple-based agri-horticultural system. The experimental design employed a Factorial Randomized Block Design with three replications and twelve treatments, resulting in a total of 36 plots. The treatments ranged from different levels of phosphorus and PSB inoculation, denoted as T1 to T12. The study assessed the impact of these treatments on nitrogen (N), phosphorus (P) and potassium (K) content in grain and straw, as well as their uptake by chickpea. Findings reveal that higher PSB levels and phosphorus applications led to increased nitrogen and phosphorus content and uptake in both grain and straw, demonstrating a significant synergistic effect. Conversely, potassium content and uptake exhibited limited response to PSB inoculation. Moreover, protein content and yield in grain and straw significantly improved with these treatments.

A Study about Temperature Induction Response (TIR): Novel Physiological Approach for Thermotolerant Genotypes in Chickpea (Cicer arietinum L.)

Pulses have been described as a "poor man's meat and affluent man's vegetable" in India. Chickpea (Cicer arietinum L.) is the third most legume crop grown during rabi season under receding soil moisture. Chickpeas is known to flourish in drought-prone conditions, but it seems to be sensitive to heat stress exceptionally during reproductive development, resulting in considerable yield loss. The performance of chickpeas under heat stress is more variable. It is crucial to develop screening tools to identify thermotolerant chickpea genotypes because of the increase in average global temperatures. In this view, a lab experiment was conducted to standardize the temperature induction response (TIR) protocol for chickpea seeds. The 70 % hydrated seeds were used for the experiment. This technique can be used as a potential tool to identify and select temperature tolerant lines at the seed stage itself from a large population. A set of six chickpea genotypes were screened for intrinsic tolerance using the standardized Thermo Induced Response (TIR) protocol. Among the genotypes JG-14, JG-11 and A-1 showed highest thermo tolerance in terms of higher survival of seeds (germination percentage) and seedlings with less per cent reduction in seedling survival, root and shoot growth. The genotypes with intrinsic heat tolerance can be explored for the development of varieties suitable for late sown conditions in Karnataka where chickpea is prone to terminal heat stress. The results of the study concluded and standardized the sub lethal temperature as 32 ºC to 50 ºC for 5 hours and 30 min, lethal temperature i.e., challenging temperature as 58 ? for 3 hours and LD 50 as 52 ? for 3 hours at seed level itself.

Study of Genetic Variability Parameters for Yield and Its Components under Normal and Late Sown Conditions in Chickpea (Cicer arietinum L.)

An investigation consisted of 50 chickpea genotypes including 4 checks viz., JG64, ICC10685, ICC4567 and NBeG47 was conducted during the rabi season of year 2022-23 at Seed Research and Technology centre, Rajendranagar, Telangana. The objective of the study was to estimate magnitude of different parameters of genetic variability for yield and its attributes. The observations were recorded for thirteen different yield and its contributing characters and the results obtained indicated that in general the phenotypic coefficient of variance was found to be higher as compared to genotypic coefficient of variance for all studied traits. High heritability along with high genetic advance (% mean) was obtained for characters like number of seeds per plant, number of filled pods per plant, seed yield per plant, number of pods per plant, number of primary branches, 100 seed weight, number of secondary branches, and plant height at normal sown conditions, which determines the presence of additive gene action for these characters and in late sown conditions the characters like number of seeds per plant, number of filled pods per plant, seed yield per plant, number of pods per plant, number of primary branches, 100 seed weight, number of secondary branches, and plant height and harvest index had shown high heritability along with high genetic advance. So, it determines the presence of additive gene action for these characters. So, that selection for these characters is beneficial in the breeding programmes.

Similarly, the nutrient content (N, P and K) was maximum in seed and stover of chickpea harvested from the plots receiving 3 t/ha Vermicompost + Rhizobium + PSB, which was statistically at par with T7 i.e., 2.5 t/ha Vermicompost + Rhizobium + PSB. The highest net return was recorded in plots treated with 50% RDF (Recommended dose of fertilizer) + Rhizobium + PSB and 75% RDF + Rhizobium + PSB with a benefit cost ratio (B: C) of 3.2 and 3.1, respectively. However, the seed yield in integrated nutrient management was comparable to recommended dose of chemical fertilizers

Studies on Dynamics of Growth Pattern in Chickpea and Their Correlations to Seed Yield under Different Sowing Dates in North– West India

The experiment was conducted with ten genotypes of chickpea (Cicer arietinum L.) viz ICCV 88503, ICCV 92944, HC- 1, HC-3, HC-5, H12-64, H13-01, H13-02, H14-01 and H14-04 for three dates of sowing i.e 15th October, 15thNovember and 15thDecember at the field in randomized block design during Rabi season of 2017-18 and 2018-19 at Pulses Section, Chaudhary Charan Singh Haryana Agricultural University, Hisar to observe the effect of sowing dates on vegetative and reproductive growth rate of chickpea genotypes at different intervals i.e 30, 60, 90, and 120 DAS with their correlations to seed yield. The dry weight of leaves, stem, pods, plant height, crop growth rate, relative growth rate and pollen viability were minimum in 15thDecember sowing and maximum in 15thOctober sowing at all intervals. Among genotypes, maximum dry matter and growth rate were observed in H12-64 and H13-01 while minimum were found in H14-04. Seed yield exhibited significant positive correlation with all traits in 15th October and 15th November sowing while non-significant was on 15th December sowing.

Response of Phosphorus and Zinc on Growth and Yield of Chickpea (Cicer arietinum L.)

A field experiment was conducted at the Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Rabi season 2022-23 on chickpea crop. The experiment was laid out in randomized block design with ten treatments and three replication. The treatments consist of 3 levels of Phosphorus (30, 40 and 50 kg/ha) and 3 levels of Zinc (10, 15 and 20 kg/ha). The treatment combinations are as follows, T1 – 30 kg/ha Phosphorus + 10 kg/ha Zinc, T2 – 30 kg/ha Phosphorus and 15 kg/ha Zinc, T3 – 30 kg/ha Phosphorus and 20 kg/h Zinc, T4 – 40 kg/ha Phosphorus + 10 kg/ha Zinc, T5 – 40 kg/ha Phosphorus + 15 kg/ha Zinc, T6 – 40 kg/ha Phosphorus + 20 kg/ha Zinc, T7 – 50 kg/ha Phosphorus + 10 kg/ha Zinc, T8 – 50 kg/ha Phosphorus + 15 kg/ha Zinc, T9 – 50 kg/ha Phosphorus + 20 kg/ha Zinc and T10 – (control). The nutrient sources were Urea, Single Super Phosphate (SSP) and Muriate of Potash (MOP), applied as per the recommended dose of 20-40-20 kg NPK/ha. As per the treatment, application of phosphorus and zinc were done as basal application. The treatment consisted of soil application of Phosphorus (30 kg/ha, 40 kg/ha and 50 kg/ha), Zinc (10 kg/ha, 15 kg/ha and 20 kg/ha) and zinc and a control (20-40-20 kg NPK/ha). The results of the experiment showed that, plant height (48.81 cm), dry weight (14.88 g) number of nodules/plant (14.67), number of pods/plant (30.07), number of seeds/pod (1.37), seed index (21.36 g), seed yield (2.66 t/ha) and stover yield (4.26 t/ha), harvest index (38.31) were recorded significantly highest with the application Phosphorus 50 kg/ha + Zinc 20 kg/ha. Maximum gross returns (152516.67 INR/ha), net returns (102367.23 INR/ha), and B-C ratio (2.04) were also obtained with the same treatment.
