The current field experiment was carried out during Rabi season of 2020-21 and 2021-22 at the Student's Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh to assess the Studies on the root architecture with nodulation of the chickpea (Cicer arietinum L.) as influence by different moisture management practices along with seed inoculation and level of zinc. The experiment was laid out in split-split plot design with 27 treatment combination comprising three moisture conservation practices namely, flat bed with 2.5 t/ha crop residue, narrow bed and furrow with 2.5 t/ha crop residue, broad bed and furrow with 2.5 t/ha crop residue in main plot and three seed inoculation (control, rhizobium and PSB) in sub-plots and three zinc level (control, 2.5 kg zinc/ha and 5.0 kg zinc/ha) in sub- sub plot with three replication. Results showed that among the different moisture management practices, used of broad bed and furrow with 2.5 t/ha crop residue were significantly enhanced root architecture, nodulation and grain yield, over the flat bed with 2.5 t/ha crop residue, respectively. Among the different Biofertilizers treatments seed inoculation with Rhizobium had significantly improved the root architecture, nodulation and yield, over control. Application of increasing levels of zinc up to 5.0 kg Zn/ha has significant influences on root architecture, nodulation and yield, over control. The combined application broad bed and furrow with 2.5 t/ha crop residue with Rhizobium and 5.0 kg/ha zinc resulted in significantly higher root architecture, nodulation and seed yield of chickpea during both the years of experimentation.

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.

The present investigation entitled, “Studies on weed management in Rabi onion (Allium cepa L.)” was carried out at the Vegetable Research Farm of Chandra Shekhar Azad University of Agriculture & Technology, Kanpur (U.P.) during Rabi season 2021with the objectives of relative efficacy of herbicides and hand weeding on weed control in onion. The experiment was laid out in Randomized Block Design for nine treatments with three replications. It was observed that the growth attributes viz., plant height (80.25 cm), leaves/plant (10.82), fresh weight of bulb (32.65 gm) and dry weight of onion (17.51 gm) were significantly higher in (T2) over rest treatments, respectively. The yields attributes viz., the polar diameter of bulb (56.70 mm), Equatorial diameter of bulb (68.58 mm) and total bulb diameter (5.97 cm) were significantly more recorded in T2, while the minimum was recorded in control. The bulbs yield (27.03 t / ha). TSS (15.43) was significantly highest in weed free check over remaining all treatments, respectively. Among the herbicidal treatment pre and post emergence application of treatment T8. The number of weeds (m2) and weed dry matter (g/ m2) were significantly noticed that weed free check (T2) was most effective treatment as it recorded less weed count 0.68/m2 and dry matter 1.25g followed by 3.63/m2 and 3.45g, respectively. The maximum weed control efficiency (93.3%) and minimum weed control index (0.00%) was significantly recorded by treatment T2, compared to remaining treatments, respectively. The gross monetary returns (Rs.3,24,360.00) were recorded higher in the treatment weed free check (T2) followed by among the herbicides T8 Rs 3,15,240/ ha and net monetary returns were recorded statistically higher in the treatment T8 Rs. 2,21,648.00. Whereas, the highest benefit cost ratio (1:3.71) was recorded in the treatment T7 followed by T6, in the present investigation.

A field experiment was carried out at the Vegetable Research Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.) during Rabi season 2021-22. The experiment consists of twenty-four treatment combinations of six sources of organic manure and four levels of major nutrients. The experiment was laid out in Factorial Randomized Block Design with replicated three times. Palam samridhi variety of broccoli was transplanted at spacing of 45x45 cm. Results of the experiment revealed that the growth characters of broccoli like plant height (cm), number of leaves plant-1, plant spread, stem diameter and Yield attributes viz total head yield per plot(kg) and total head yield (q/ha) were significantly higher under M6 (FYM 20t + Vermicompost 5 t + Poultry manure 5 t ha-1) source of manure which was at par application of M4 (Vermicompost 5 t ha-1) whereas in case of major nutrients it was significantly higher under application of (140:80:80 kg NPK ha-1) but it was at par with (120:60:60 kg NPK ha-1) and significantly superior to rest sources of organic manure.
