ABSTRACT
A chlorophyll meter measures the greenness of leaves and can indicate the chlorophyll content and N status. Therefore, by using a chlorophyll meter, proxy information related to the leaf N content could be obtained and this would avoid the need of laborious laboratory analysis. Keeping in this view a field experiment was conducted during winter (Rabi) 2019 growing season at the experimental field of JNKVV, Jabalpur to estimate crop nitrogen (N) and chlorophyll content in wheat using SPAD. The treatment comprised of 3 sources of nutrient M1- Inorganic sources (NPK fertilizers), M2- organic sources (FYM, vermicompost, biofertilizers Azotobacter and PSB) and M3- Integrated sources (50% Inorganic + 50% organic) as main treatments and 5 NPK levels S1- control, S2- 100% RDF, S3- 150% RDF, S4- 200% RDF, S5- Based on soil test value for target yield of 6t ha-1 as sub treatments were replicated thrice in a split plot design. The results showed that the correlation (r = 0.94, 0.90, 0.92 and 0.94, respectively) and coefficient of determination (R2 = 0.96, 0.94, 0.83 and 0.94, respectively) was significantly and positively correlated with SPAD and nitrogen concentration in leaf. Similarly significant and positive correlation (r = 0.84, 0.76, 0.78 and 0.71, respectively) found with SPAD and total chlorophyll values. Coefficient of determination (R2) SPAD with chlorophyll and leaf N concentration proved to be significant (R2 = 0.75, 0.76, 0.54 and 0.85, respectively) at different growth stages. It was concluded that SPAD meter are useful for the determination of proxy chlorophyll and total nitrogen content of wheat plant.
ABSTRACT
A field experiment on wheat (Triticum aestivum L.) was carried out during two consecutive rabi seasons 2021-22 and 2022-23 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh, India. The soil of the experimental field was sandy loam in texture, low in organic carbon and available nitrogen, but medium in available phosphorus and available potassium having slightly alkaline pH (8.7) with an electrical conductivity of 0.327. The field experiment allocated three moisture regimes in main plots, I1: irrigation at IW/CPE ratio of 0.7, I2: irrigation at IW/CPE ratio of 0.9 and I3: five irrigations at critical stages (CRI, LT, LJ, F and M) and six integrated nutrient management (INM) modules in sub-plots, N1: control, N2: 100 % RDF (150:75:60 kg NPK/ha), N3: 125 % RDF, N4: 50% RDF+PM @ 2.5 t/ha, N5: 50% RDF+PM @ 2.5 t/ha+Azotobacter+PSB+KMB, N6: 50% RDF+PM @ 2.5 t/ha+NPK consortia were tested in split plot design with three replications. On pooled basis of two years experimentation the results showed that, the irrigation applied at critical stages (CRI, LT, LJ, F and M) resulted in significantly (P<0.05) tallest plants, more number of physiologically active leaves/plant at 50% flowering stage, days taken to 50% flowering, days taken to maturity, spike length, grains weight/spike, grain yield (48.7 q/ha), protein content (11.1 %) in grains and crop water use (541.9 mm) over IW/CPE ratio of 0.7. While, the reverse trend was noticed for soil pH and electrical conductivity, being maximum under the IW/CPE ratio of 0.7. Moreover, the highest water productivity was obtained with 0.9 ratio followed by 0.7. In respect of INM modules, the tallest plants, more of days taken to 50% flowering, days taken to maturity and soil pH were noticed with N3 treatment, which was significantly (P<0.05) higher over the rest of the treatments, except plant height, being on par with N2 and N6 and soil pH which did not show any significant variation during both the years. While, the maximum number of physiologically active leaves/plant, grains weight/spike, protein content (11.2%) in grains and electrical conductivity were recorded under N5. However, the physiologically active leaves/plant and grains weight/spike was significantly (P<0.05) superior over control and protein content in grains under N1 and N2. Moreover, the longest spike, grain yield (51.0 q/ha), crop water use (481.0 mm) and water productivity (6.38 kg/ha-mm) were registered with N6, being significantly (P<0.05) superior over the control. Further, this treatment out yielded control and RDF by 23.7 and 6.3 %, respectively.

ABSTRACT
At the United University's Agricultural Research Farm in Rawatpur, Jhalwa, Prayagraj (U.P.), India, during the Kharif season of 2022, a research on green gram (Vigna radiata L.) was carried out to examine the effects of integrated nutrient management on growth, yield, and economics. On green gram (Vigna radiata L), the experiment was conducted using a randomized bock design with three replications in all allowable combinations of inorganic fertilizers, Rhizobium, and PSB together with FYM. This study showed that plant height (91.99 cm), dry weight (105.45 g), and number of root nodules (111.33) were all significantly enhanced by 100% RDF + 5.0 tonnes FYM ha-1 + Rhizobium and PSB seed inoculation. In terms of increasing yield and yield-related indicators, such as number of pods plant-1 (31.43), number of seeds pod-1 (12.46), test weight (37.26 g), and harvest index (34.90%), the same treatment combination likewise showed the best results. As a result, adding farm yard manure at a rate of 5 tonnes per hectare coupled with Rhizobium and PSB increased yield compared to the control. But using 100% RDF, bio fertilizer, and FYM @ 5.0 tonnes ha-1 greatly boosts gross returns (? 104,120.00), net returns (? 76,017.00), and benefit: cost ratio (2.70). These results showed that the addition of organic matter, inorganic fertilizers, and bio-fertilizers all combined to boost yield while using various nutrition sources.
ABSTRACT

Parbhani during kharif season of 2015 to study the “Integrated Nutrient Management in Kharif Sorghum (Sorghum bicolor L.)”. The experiment was laid out in randomized block design with three replications and variety CSH -16 as test crop along with nine (09) treatment combinations. The quantity of organic and inorganic fertilizer dose was calculated and applied in the plots as per the treatments. Sowing was done on 21th June 2015 by seeds are dibbling and distance between 45cm x 15 cm. The crop was harvested at physiological maturity and data on yield attributes and yield were recorded. The study revealed that the application of 75% RDN through inorganic fertilizer + 25% RDN through vermicompost + seed treatment with PSB + Azospirillum (T8) gave significantly higher GMR (76,068 ha-1), NMR (37,999 ha-1) and B:C ratio (2.07) over rest of the treatments, however it was at par with application of 75 % RDN through inorganic fertilizer + 25% RDN through FYM + seed treatment with PSB + Azospirillum (T7).
ABSTRACT
Integrated nutrient management (INM) is a holistic approach that involves the application of organic and inorganic fertilizers to improve soil health and crop productivity. The research study was conducted to demonstrate the effective use of INM on soil health in Green gram. We used a randomized block design (RBD) with four levels of poultry manure @ 0, 50, 75 and 100% ha-1, four levels of nitrogen, phosphorous and potassium@ 0, 50, 75 and 100% ha-1 and rhizobium seed treatment. The revealed that treatment T9 (N20P40K40 kg ha-1 + PM @ 5 t ha-1 and Rhi @ 200g 10 kg-1 Seed) resulted in a slight change in soil pH 6.82, electrical conductivity (EC) 0.198 dS m-1. In post-harvest soil of fertilizers observations showed significant increase in pore space 49.20 %, water holding capacity 47.59 %, organic carbon 0.49 %, and available N 334.23 kg ha-1, P 34.58 kg ha-1, K 202.83 kg ha-1. The increase in NPK was found to be significant (P<0.05) among other treatments in Green gram cultivation and soil quality improvement. The application of N P K with poultry manure was a magnificent source of fertilization.

ABSTRACT
The status of DTPA extractable micronutrient (Zn, Cu, Fe and Mn) in response of continuous application of different inorganic and organic fertilizer combination in a 48 years old ongoing long-term fertilizer experiment (AICRP-LTFE) were investigated in Vertisol at Department of Soil Science, and Agricultural Chemistry, JNKVV, Jabalpur under intensive cultivation of soybean- wheat cropping system in 2021. The treatments selected for the study were: control (T1); 100% NP(T2); 100% NPK (T3); 100% NPK+FYM (T4); 100% N(T5); 50% NPK (T6); 150% NPK (T7). Application of FYM along with balance fertilizer (100% NPK) significantly increased the micronutrients availability in soil. On contrast, Imbalance fertilization caused a lower level of micronutrients in soil even below to the critical limit in case of zinc. A decreasing trend with increase in soil depth irrespective of type of nutrient management and micronutrient type was evident in the study. Findings of the present study emphasized the application of balance fertilization along with organic sources like FYM for sustaining micronutrients availability in Vertisol under soybean-wheat cropping system.

ABSTRACT
The cultivated tomato Solanum lycopersicon L., a commercial annual crop that is grown all over the world for local consumption or export purpose. It belongs to the Solanaceae family and has diploid chromosome number (2n= 2X= 24). Application of fertilizers, insecticides and herbicides is crucial for improving productivity per unit area, however excess usage more than that of a recommended dose can lead to issues including environmental contamination (air, water and soil pollution). According to a thorough study, farmers exposed to chemical insecticide spray for a period of 18 months experience impaired vision symptoms like eye stinging or burning (18.42%), dry sore throat (21.05%), blurred vision (23.68%), nose burning (28.9%), shortness of breath and excessive sweating (34.2%), and skin itching or redness (50.0%). The purpose of this brief review article is to explore the function of various organic and inorganic nutrient sources in tomato crop by analysing previous works and studies. Integrated Nutrient Management (INM) is an approach that boosts the agricultural production and safeguards the environment for future generations.

T1= N120P60K100S20 kg/ha (Recommended dose of NPKS as control), T2= N120P60K100S20 kg/ha + CD (5 t/ha), T3= N120P60K100S20 kg/ha + VC (4 t/ha), T4= N120P60K100S20 kg/ha + MSC (4 t/ha), T5= N120P60K100S20B0.6Mo0.54 kg/ha + CD (5 t/ha), T6= N120P60K100S20B0.6Mo0.54 kg/ha + VC (4 t/ha), T7= N120P60K100S20B0.6Mo0.54 kg/ha + MSC (4 t/ha), T8= N120P60K100S20 kg/ha + CD (5 t/ha) + Bio. (5 kg/ha), T9= N120P60K100S20 kg/ha + VC (4 t/ha) + Bio. (5 kg/ha), T10= N120P60K100S20 kg/ha + MSC (4 t/ha) + Bio. (5 kg/ha), T11= N120P60K100S20B0.6Mo0.54 kg/ha + CD (5 t/ha) + Bio. (5 kg/ha), T12= N120P60K100S20B0.6Mo0.54 kg/ha + VC (4 t/ha) + Bio. (5 kg/ha) and T13= N120P60K100S20B0.6Mo0.54 kg/ha + MSC (4 t/ha) + Bio. (5 kg/ha). The experiment was laid out in a Randomized Complete Block Design (RCBD) having single factor with three replications. Data were recorded on growth, yield components of cauliflower and significant variation was observed for most of the studied characters. Under this investigation, it was revealed that the highest yield (36.34 t/ha) with net return (Tk. 524202) and BCR (3.59) was obtained from T12 (N120P60K100S20B0.6Mo0.54 kg/ha + VC (4 t/ha) + Bio. (5 kg/ha) treatment. On the other hand, the lowest yield (13.50 t/ha) with net return (Tk. 137869) and BCR (2.04) was obtained from T1 (N120P60K100S20 kg/ha) treatment. So, economic analysis revealed that T12 (N120P60K100S20B0.6Mo0.54 kg/ha + VC (4 t/ha) + Bio-fertilizer (5 kg/ha) treatment appeared to be the best for achieving the higher growth, yield and economic benefit of cauliflower.
ABSTRACT
The field experiments were conducted on sandy loam soil at New Delhi, during 2007 and 2008 to investigate the effect of conservation tillage, irrigation regimes (sub-optimal, optimal and supra-optimal water regimes), and integrated nutrient management (INM) practices on soil biological parameters in wheat cultivation. The conservation tillage soils has shown significant (p<0.05) increase in soil respiration (81.1 percent), soil microbial biomass carbon (SMBC) (104 percent) and soil dehydrogenase (DH) (59.2 percent) compared to the conventional tillage soil. Optimum water supply (3-irrigations) enhanced soil respiration over sub-optimum and supra-optimum irrigations by 13.32 percent and 79 percent respectively. Soil dehydrogenase (DH) activity in optimum water regime has also increased by 23.33 percent and 8.18 percent respectively over the other two irrigation regimes. Similarly, SMBC has also increased by 12.14 percent and 27.17 percent respectively in soil with optimum water supply compared to that of sub-optimum and supra-optimum water regime fields. The maximum increase in soil microbial activities is found when sole organic source (50 percent Farm Yard Manure+25 percent biofertilizer+25 percent Green Manure) has been used in combination with the conservation tillage and the optimum water supply. Study demonstrated that microbial activity could be regulated by tillage, water and nitrogen management in the soil in a sustainable manner.
ABSTRACT
OBJECTIVES: We examined the effects of INM 176 (K-1107) compared with placebo on the cognitive functions of 92 old aged subjects with cognitive impairment. METHODS: This was a prospective, 12 week, double-blind, placebo-controlled clinical trial. The elderly who achieved a score of less than 25 points on the K-MMSE or showed a high risk of Alzheimer's disease from the 7-Minute Neurocognitive Screening Battery were considered to have objective impairment and were selected as subjects for this study. The subjects were randomized to placebo or INM 176 group. The outcome measures were from the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog), the Instrumental Activities of Daily Living (IADL) and the Korean Geriatric Depression Scale (KGDS) and two kinds of computerized priming tests. After setting the total error score in the Alzheimer's Disease Assessment Scale-Cognitive section (ADAS-cog) as the repeated measurement factor, an analysis of variance of the combined factor design was done between the placebo and INM 176 group. RESULTS: The interaction effect of time (pre- and post- trial) and group (placebo and INM 176 group) was significant in the analysis of the ADAS-cog's total error score. The INM 176 group's total error score in the ADAS-cog decreased significantly (p<0.01), whereas the placebo group showed a slight increase. The mean changes in IADL and GDS from baseline scores favored in the INM 176 group than in the placebo group. Outcome changes of ADAS-cog, IADL, KGDS scores during the 12 week clinical trail of INM 176 and placebo demonstrated favorable responses in the INM176 administered group. CONCLUSIONS: This is a preliminary clinical trial result of INM176 as a memory pill. Based on these results, INM176 may be a candidate molecule for the improvement of cognitive functions, including memory. Further clinical trial should demonstrate its efficacy.
