“…Besides more number of cobs per plant produced by G-5414 and higher weight of each cob than the other two varieties might have increased the cob yield as number of cobs per plant and weight of each cob are vital yield attributing character. Similar differences in cob yield owing to different varieties were recorded by Pandey et al, (2000), Ramachandrudu et al, (2013), Asaduzzaman et al, (2014) and Kumer et al, (2015).…”

Baby corn (Zea mays L.) is a short duration crop, relatively new introduction in India and a potential option for raising farmer’s income being a high value crop. This crop may open new alternatives since fits well in the cropping systems and grown year round in a wide range of climatic conditions. Production technologies of baby corn differ from maize thus, development and standardization of location specific agro-techniques are required before popularization among the farmers. Nitrogen (N) deficiency is a wide spread phenomenon in Indian soils and its proper management is of enormous significance from economic and environmental point of view. Efficient utilization depends on the right time, method and optimum N application synchronizing with the crop demands. Studies so far suggest N application in variable rates and proportions for different agro-ecological zones. Yield increases with N rates up to certain level but optimum economic N dose is found independent of plant densities. Baby corn-legume intercropping may be a viable option to improve N-fixation and system productivity. More studies needed on N management in baby corn based cropping systems. Integrated nutrient management (INM) practice should be adopted as core strategy for sustainability and reduce dependency on chemical fertilizers. Combined approach (soil application + foliar spray) enhances yield and quality in winter baby corn. Concentration and timing of urea foliar spray are two crucial factors to harness the desired benefit. Scope to harvest combined product (baby corn + green / mature cob) and its interaction with N may be explored to provide more flexibility to the farmers. Optimization of N quantities depends on season and location. Site specific nitrogen management (SSNM) approach can address the spatial and temporal variations for efficient N-management. However, cost effective and user’s friendly precision tools may be a viable option considering the real farm situations.

“…They noticed nitrogen had its profound influence on vegetative and reproductive growth of the crop. Yield attributes of maize increased with increased rates of N might be due to the fact that application of nitrogen to the maize plants maintained greenness of leaves for longer period which in turn helped in greater dry matter accumulation and this might have contributed much as a major source for the development of sink and thereby improved the yield attributes (Asaduzzaman et al, 2014) Reena Sharma et al /Arch.

Nitrogen is one of the key factors for higher grain production of hybrid maize (Zea mays L.). The use of improved varieties and optimal use of nitrogen (N) fertilizer is important for exploiting yield potential of maize. This work was carried out to evaluate the effects of N rates on grain yield and yield attributing traits of hybrid maize. Two hybrids (RML-86/RML-96 and RML-95/RML-96) and five levels of nitrogen (120, 150, 180, 210 and 240 kg N/ha) were evaluated at research field of National Maize Research Program (NMRP), Rampur, Chitwan, Nepal in spring season of 2017 and 2018. The experiments were conducted in two factorial randomized complete block design (RCBD) with three replications under rainfed condition. The pooled analysis (2017 and 2018) showed that the highest grain yield 10.5 and 10.5 t/ha were given by hybrids RML86/RML96 and RML95/RML96, respectively with the use of 150 kg N/ ha in 2017. The hybrids RML-86/RML-96 and RML-95/RML-96 produced the highest grain yield 7.49 and 7.68 t/ha, respectively with the use of 150 kg N/ha in 2018. The mean grain yield (2017 and 2018) showed that both maize hybrids produced the highest grain yield 10.5 t/ ha in 2017 and 7.58 t/ha year in 2018 with the application of 150 kg N/ha. The application of nitrogen fertilizer on grain yield was found significant (P<0.05) in both years. Therefore, the application of 150 kg N/ha has significantly increased grain yield of maize, Therefore, this dose of nitrogen can be recommended for higher maize production in Chitwan, Nepal in spring season under rainfed condition.
