A field experiment was conducted at the Crop Research Farm (CRF), Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (UP) during the year 2021 zaid season. To find out suitable Nitrogen, zinc and iron levels for profitable baby corn yield. The experiment comprised of 9 treatments with different combinations of nitrogen, zinc and iron replicated thrice in a Randomized Block Design. The main objective of the experiment was to evaluate the Effect of Nitrogen, Zinc and Iron on growth and yield of baby-corn (Zea mays L.). The nitrogen levels include [70, 80 and 90 kg/ha] where-as levels of zinc (0.5%) and iron (0.2%) From the present investigation The results showed that viz: Plant height (169.75 cm),Number of leaves per plant (13.80) plant dry weight (113.09 g/plant) were recorded significantly higher in 90kg/ha Nitrogen along with 0.5% Zinc and 0.2% Iron. Number of cobs per plant (1.69), cob length (18.50 cm), cob girth (8.10cm), cob weight with husk (48.85g), cob weight with out husk (13.80 g), cob yield with husk (11.75 t/ha), cob yield without husk (4.35 t/ha), green fodder (33.58t/ha) and the profitable production of baby corn can be secured by 90kg/ha Nitrogen + [0.5% Zinc + 0.2% Iron].

Study of Genetic Variability, Character Association and Path Analysis in Greengram [Vigna radiata (L.) Wilczek

A set of 21 of greengram were evaluated for studying of “Study of Genetic Variability, Character Association and Path Analysis in Greengram [Vigna radiata (L.)Wilczek]”. The experiment was conducted in a Randomized Block Design with three replications during the kharif season, 2021 in the crop research farm of Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. For all 13 characters, the analysis of variance revealed a significant difference between genotypes. A favourable and very significant link between seed yield per plant and Days to maturity and Harvest Index was found in the current study using both phenotypic and genotypic correlation coefficients. Maximum positive direct effects was depicted by Harvest Index (%), Number of seeds per pod and Plant height (cm) at both phenotypic and genotypic levels. Path analysis further revealed that direct effect of Harvest Index (%), No. of seeds per pod and Plant Height (cm) was of high magnitude. The significant indirect effect through these features also contributed to the high positive relationship of other characters with grain yield per plant (g). This suggested that the above three traits' direct and indirect effects accounted for the majority of the seed yield. As a result, these genotypes may be encouraged for cultivation as well as in next breeding programmes to create better cultivars for sustainable agricultural production.

India. To study the Response of Nitrogen and Boron on growth and yield of Lentil. The treatments consist of nitrogen 10, 20, 30 kg/ha and boron 1.0, 1.5, 2.0 kg/ha. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.35%). Results revealed that the higher plant height (36.40 cm), higher plant dry weight (22.70 g/plant), higher number of pods/plant (174.44), higher number of seeds/pod (1.72), higher seed yield (1.75 t/ha) and higher stover yield (2.67 t/ha) were significantly influenced with application of Nitrogen 30 kg/ha + Boron 2.0 kg/ha. Higher gross returns (INR 89,059/ha), higher net returns (INR 59,652/ha) and higher B:C ratio (2.03) were also recorded in treatment-9 (Nitrogen 30 kg/ha + Boron 2.0 kg/ha).

Effect of seaweed (Kappaphycus alvarezii) extract on rainfed aerobic rice (Oryza sativa L.)

Rice is grown throughout the year in India, in a variety of agro-climatic conditions, and it is grown on 43.39 million hectares with a production of 159.20 MT with an average productivity of 3623 kg/ha. Aerobically produced rice may be an option for farmers on rainfed areas where rainfall is not sufficient or availability of water is rare and expensive too for flooded rice production but enough for cultivation of upland rice. The field experiment took place at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh, India, during the kharif season of 2020. The experiment was done by using Randomized Block Design with three replications. The findings of the experiments revealed a considerable rise in the growth parameter viz., plant height (46.0 cm), total tillers/m2 (564.3), plant dry matter accumulation (1938.0 g/m2), leaf area index (19.07) and crop growth rate (49.47 g/m2/day) and yield attributing parameters viz., effective tillers/m2 (362.3), weight of panicle/m2 (856.9), number of filled grain/panicle (115.7), grain yield ( 4.7 t/ha), test weight (28.9 g), straw yield (11.3 t/ha) with foliar application of 7.5 percent Kappaphycus alvarezii seaweed sap four times, plus RDF and two foliar applications of 10% K-sap yielded the greatest harvest index (32.7%).
