PERFORMANCE OF HYBRID MAIZE (Zea mays L.) IN DIFFERENT LEVELS AND TIME OF NITROGEN APPLICATION IN INDO-GANGETIC PLAINS OF EASTERN INDIA

Abstract

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.

Effect of different levels of nitrogen on growth and yield of hybrid maize (Zea mays L.) varieties

“…Maize is one of the world's leading crops ranked in the third position in the world cereal crop production after wheat and rice (FAO, 2018). It is a short duration, quick growing and widely grown crop with high potential, there are no cereal crops with such an immense potentiality, so it is called as "queen of cereals" (Begam et al, 2018). It is a multipurpose traditional crop generally grown for food, feed and fodder (KC et al, 2015).…”

To Study the Effect of Foliar Spray of Nano Fertilizer on Growth Characters of Rabi Maize (Zea mays L.) in Mandsaur Region (MP), India

“…Maize (Zea mays L.) is one of the important cereal crops belonging to the Poaceae family, which ranked third after wheat and rice crops in terms of productivity, production and cultivated area in the world [1]. It is a short duration, quick growing and widely grown crop with high potential, there are no cereal crops with such an immense potentiality, so it is called as "queen of cereals" [2]. Major maize growing states are Bihar, Maharashtra, Tamil Nadu Gujarat, West Bengal and Telangana.…”

A Comparative Analysis of Local Maize Hybrids, Versus Commercial Maize Hybrids: Assessing Yield and Yield Components

“…It is referred to as the "queen of cereals" since it is a cereal crop that can be cultivated extensively, quickly, and for a short amount of time. No other cereal crop has such great potential (Begam et al, 2018). It is a classic multifunctional crop that is often farmed for food, fuel, feed & fodder, and industrial uses (KC et al, 2015), making it a vital crop for global food security and economic development.…”
