A field experiment was carried out during Kharif 2020 and 2021 at Kanpur,  India  to find out the effect of FYM, phosphorus and PSB on growth and yield of  Green gram variety Shweta. There were twenty treatment combinations of 4 levels of  FYM t ha-1: control (F0), 1.0 t (F1), 2.0 t (F2), and 3.0 t (F3), and  5 levels of phosphorus kg ha-1 and PSB viz.,  PSB only (P1), 20 kg P2O5 (P2), 20 kg P2O5 + PSB (P3), 40 kg P2O5 (P4) and  40 kg P2O5  + PSB (P5) laid out in Factorial Randomized Block Design  and replicated thrice. The FYM, phosphorus, and PSB were applied as per treatment. The higher growth attributes and number of pods per plant, pod weight plant-1, test weight, seed yield, gross income, net income  and B:C ratio  were recorded with  3t FYM/ha among the FYM levels and 40 kg P2O5 /ha + PSB among the levels of PSB and phosphorus.

Considering the food and nutritional security concerns, and post green revolution second generation problems i.e. increasing input use with declining efficiency trends, deteriorating soil health, depleting water resources, pollution, and narrowing profits at the end of farmers, an investigation was carried out on Wheat (Triticum aestivum) crop during 2019-20 at the crop research centre of SVPUA & T, Meerut (U.P.) to overcome these problems. Novel nutrient sources and their modes of applications with 14 treatments consisting of control, basal applications of recommended 100% NPK (150:60:40), 75% NPK (112.5:45:30) + water spray + nano N (4 ml l-1) + bio nano P (40 ml l-1) + bio nano K (40 ml l-1) + bio nano Zn (10 ml l-1) in various combinations were attempted on wheat variety DBW17 in randomized complete block design (RCBD) with three replications. The results of the study revealed that wheat grown with 75% NPK + nano nutrients (N + P + K + Zn) attainted significantly better growth as reflected by taller plants (91.7 cm), more no. of tillers m-1 row length (61.8), and higher dry matter accumulation m-1 row length (239.2), recorded at harvest with grain yield of (52.4 q ha-1). The crop contained 53.2 ppm Zn in grain and 31.8 ppm Zn in straw. Applications of nano nutrients – N, P, K, Zn and N +P + K + Zn +75% NPK worked synergistically and increased grain yields by 17.9, 15.7 14.5, 16.5 and 26.9% over 100% NPK. Thus, the wheat crop grown with the application of Nano-N + 75% NPK followed Nano-Zn + 75% NPK by had attained better growth (plant height, no. of the tiller, dry matter accumulation, yield (grain), nutrient content, and nutrient uptake.

A field experiment was conducted on Mung Bean (Vigna radiata L.) during the autumny season of 2020-21 at Technology Park of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). The experiment was laid out in randomized complete block design (RCBD). Results revealed that the growth parameters of mung bean viz., number of (331229 plants/ha), plant height (67.7 cm/plant), trifoliate leaves/plant (12.7), number of branches/plant (4.5), dry matter accumulation (18.7 g/plant), leaf area index (5.72), CGR (7.6 g/m2/day) 50-at harvest and grain yield of (1,106 kg/ha) improved by various treatments over control, being highest under NPK Consortia+ZSB, each @ 20 ml/kg. Similarly, this treatment also produced an accumulation of 59.8% more dry matter/plant than control. However, application of NPK Consortia+ZSB, each @ 20 ml/kg recorded higher available N, P, K and Zn followed by NPK Consortia @ 20 ml/kg and RDF (20:40 kg/ha).

This experiment was carried out for two consecutive years (2020 and 2021) during Kharif season at Student’s Instructional Farm (SIF) of Department of Agronomy, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur, Uttar Pradesh, India to assess the effect of Farm Yard Manure (FYM), phosphorus levels and Phosphate solubilizing bacteria (PSB) on growth and yield of Green gram with variety Shweta (K.M. 2241) was laid out in Factorial Randomized Block Design (FRBD) and replicated thrice. This experiment included 20 treatment combinations, the levels of FYM viz., control (F0), 1.0 t (F1), 2.0 t (F2) and 3.0 t (F3) and levels of phosphorus viz., PSB only (P1), 20 kg P2O5 (P2), 20 kg P2O5 + PSB (P3), 40 kg P2O5 (P4) and 40 kg P2O5 + PSB (P5). The result of this study showed the interaction effect of FYM, phosphorous & PSB were non-significant. In the different levels of FYM, the 3.0 tons ha-1 FYM resulted in significantly higher growth attributes viz., plant height (40.60cm) at maturity, No. of branches plant-1 (4.95) at maturity, number of nodules plant-1 (24.85) at 60 DAS and dry weight of nodules plant-1 (14.34g) at 60 DAS, yield attributes viz., number of pods plant-1 (14.70), weight of pod plant-1 (7.44g), pod length (6.55cm) , and test weight (41.36g), yield viz. grain or seed yield (894kg ha-1) and quality parameters viz., protein content (23.90%), protein yield (214kg ha-1), nutrient contents i.e. nutrients uptake by grain and straw of Green gram compared to other treatments and control. Among the different levels of phosphorous & PSB, 40 kg P2O5 ha-1 + PSB resulted the highest values of growth attributes viz., plant height (38.54cm) at maturity, No. of branches plant-1 (4.52) at maturity, number of nodules plant-1 (23.19) at 60 DAS and dry weight of nodules plant-1 (13.42g) at 60 DAS, yield attributes viz., number of pods plant-1 (13.99), weight of pod plant-1 (6.57g), pod length (6.35cm), and test weight (40.85g), yield viz. grain or seed yield (825 kg ha-1), and quality parameters viz., protein content (23.84%), protein yield (197kg ha-1), nutrient contents i.e. nutrients uptake by grain and straw. Thus, it is possible to maximize the growth attributes, yield attributes, yield and quality of Green gram with application 3.0 tons ha-1 FYM and 40 kg P2O5 ha-1 + PSB.

Chickpea (Cicer arietinum L.) commonly known as gram or Bengal gram belongs to the family Leguminaceae (Fabaceae). It's one of the most important rabi season pulse crops grown in India for economic importance and to improve soil fertility. The productivity of chickpea is low despite of having high-yielding varieties and new agronomic practices. One of the causes of poor productivity is the infestation of weeds in the field of chickpea. It is a poor competitor to weeds because of its slow growth rate and limited leaf area development at early stages. To overcome this, a field experiment was conducted during the rabi seasons of 2021-22 at the Agronomy Research Farm of the Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (UP). Replicated thrice set of eleven treatments (T1) Pendimethalin 30 EC @ 1.0 kg a.i./ha PE,(T2) Imazethapyr 10% SL @ 0.06 kg a.i./ha PoE,(T3) Clodinafop propargyl 15 WP @ 0.06 kg a.i./ha PoE, (T4) Propaquizafop 10 EC @ 0.075 kg a.i./ha PoE,(T5) Quizalfop ethyl 5 EC @ 40 g a.i./ha PoE, (T6) Pendimethalin 30 EC @ 1.0 kg a.i./ha PE followed by (Fb) Imazethapyr 10% SL @ 0.06 kg a.i./ha PoE, (T7) Pendimethalin 30 EC @ 1.0 kg a.i./ha PE fb by Propaquizafop 10 EC @ 0.075 kg a.i./ha PoE, (T8) Pendimethalin 30 EC @ 1.0 kg a.i./ha PE fb by Clodinafop propargyl 15 WP @ 0.06 kg a.i./ha PoE, (T9) Pendimethalin 30 EC @ 1.0 kg a.i./ha pE fb by Quizalfop ethyl 5 EC @ 40 g a.i./ha PoE, (T10) Weed free and (T11) Weedy check, was laid out in randomized block design. Weed management was done as per treatment. Other crop management practices were followed as per the recommendation of the area. Pendimethalin @1.0 kg a.i./ha PE fb Clodinafop propargyl 15 WP @ 0.06 kg a.i./ha as PoE during the experiment recorded significantly less weed density, weed dry matter, and higher weed control efficiency, yield attributes (number of pods/plant, number of seeds/pod and test weight), yield (grain yield, stover yield, biological yield, and harvest yield). Economically it recorded higher gross returns, the net return, and B:C ratio was noted and proved to be more remunerative as compared to other herbicide applications used in chickpea crop.
