“…The higher grain yield of the above genotypes could be correlated to the higher number of Cobs per plant, Cob length, Grain row per cob, Number of grains per row and Seed index. Similar results have also been reported by Kumar and Kandel [9] and Manjunatha et al [10,[11][12][13][14][15][16].…”

Maize (Zea mays L.) is one of the most versatile emerging crops having wider adaptability under varied agro-climatic conditions. Globally maize is Known as “Queen of cereals” because it has highest genetic yield potential among the cereals To find out the best Genotype among the maize hybrids, a field experiment was conducted during the kharif season of 2022 at the experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. The study was conducted to evaluate some agronomic characters of maize genotypes under “Agronomic Evaluation of Maize (Zea mays L.) Genotypes under agro-climatic conditions of Prayagraj, Uttar Pradesh in Kharif-2022". The experiment was laid out in a randomized complete block design which consisted of ten maize genotypes as treatments. The treatments were replicated three times. The result of the study indicates that among different maize Genotypes, M-410 produced significantly higher plant height (218.35 cm), number of leaves per plant (15.60), dry weight per plant (152.24g), cob length (19.26 cm), number of rows per cob(14.85), number of grains per row ( 37.03), seed yield (9.54 t/ha) and stover yield (21.62 t/ha). Based on the result obtained M-410 is most suitable, productive economical to be grown in the study area and therefore recommended as planting material in the agroecological zone.

“…Nutrient requirement is very high in case of maize crop because it is an exhaustive crop and its productivity closely depends on nutrient management particularly that of nitrogen. It plays a vital role for increasing the grain yield and their contribution is 40-50% (Begam et al, 2018). Splits application of nitrogen proved to be a best practice in sense that it reduced various losses and resulted to higher dry matter accumulation and growth of plant as compared to sole application as reported by many scientists (Haque et al, 2001;Harikrishna et al, 2005).…”

Present experiment was conducted with four nitrogen levels (75, 100, 125 and 150 kg Nha -1 ) with three time of application viz. S1 (½ as basal + ½ at 25 DAS), S2 (½ as basal + ½ at 45 DAS) and S3 (½ as basal + ¼ at 25 DAS + ¼ at 45 DAS) in split-plot design, during rainy season of 2016 and 2017 at Gayeshpur farm of B.C.K.V. Nadia, West Bengal, India on hybrid maize (P3377). Result of present study revealed that plant height increased with the increase of N level from 75 to 150 kg ha -1 . LAI and aerial dry matter accumulation were significantly higher at 125 kg N ha -1 and lowest in 75 kg N ha -1 at harvest. Higher grain yield (5.99 t ha -1 ) and cob/plant, grain/cob, seed index and B:C ratio (1.75) were also obtained from 125 kg N ha -1 . Regarding time of application of N, though treatment S1, exhibited higher plant height in the initial stage but ultimately treatment S3 recorded with better result. Higher grain yield of 5.63 t ha -1 and B:C ratio (1.64) was obtained with N applied in thrice (½ as basal + ¼ at 25 DAS + ¼ at 45 DAS) followed by S2. Thus from the pooled data of two years experiment it can be inferred that nitrogen level of 125 kg ha -1 and applied in three growth stages (½ as basal + ¼ at 25 DAS + ¼ at 45 DAS) in maize can be used for yield increase and higher profit.

“…in India. Because of its monoecious character, superior carbon dioxide assimilation capacity, wider flexibility, and high yielding potential, maize is known as the 'Queen of Cereals' (Begam et al, 2018) [1] It is cultivated throughout the year in all the seasons and grown around the globe. The nutritional value of maize is high as it contains 72% starch, 10% protein, 8.5% fibre, 4.8% oil, 3.0% sugar and 1.7% ash.…”

A field experiment was conducted during Kharif season of 2023 at Crop Research Farm Department of Agronomy. The treatment consists of three different spacing of geometry (45 cm × 25 cm, 60 cm × 15 cm and 60 cm × 20 cm) and three levels of Seaweed Extract (5% RDF, 10% RDF and 15% RDF) and along with NPK and a control (120-60-40 NPK kg/ha). The research should significant effect on different growth parameters and yield parameters i.e., plant height (178.37 cm), dry weight (83.4 g), number of cobs/plant (1.60), number rows per cob (16.99), number grains per row (29.27), seed index (22.45 g), grain yield (5.61 t/ha) and stover yield (11.82 t/ha). Crop sown at Spacing of 60 cm × 15 cm + Seaweed Extract at 15% RDF is recommended.
