A young, unfertilized, dehusked maize ear that has just started to multiply is called baby corn (the baby phase of the maize cob). It is usually harvested when the silk is between two and three cm long, two to three days following silking. Depending on the agro-climatic circumstances, baby maize can be grown three to four times a year after maturing for 60 to 75 days. As a pre-kharif crop with a brief growing phase, baby maize provides a distinct benefit by making use of fields that would otherwise stay fallow during the periods when rice and wheat are turning over. Higherearnings can be made from the early harvest and selling of baby maize ears. Additionally, untranslocated photosynthates remaining in the green stover can be used as a good source of nutrient-rich green fodder for live stock, which boosts the production of dairy products and meat. As the crop with the highest nutritional content, baby maize needs exceptionally high-quality nutrients to be used efficiently and to increase yield. Although the production of baby corn can be increased by applying artificial fertiliser, doing so will eventually compromise the sustainability of the expanding field. Furthermore, farmers' financial stability and soil health can be preserved by replacing a portion of chemical fertilisers with organic sources of nutrients. However, the replacement of 25% and 50% of the nitrogen with organic sources (FYM/Vermicompost/Poultry Manure) had a greater positive impact on the production of baby maize, the yield of fodder, the quality and economics of the nutrient uptake, and the soil fertility status.

Nitrogen (N) is a key nutrient required for higher yield and better quality of maize that leads to the achievement of food self‐sufficiency in many developing countries. A two‐year field experiment was conducted to evaluate the effect of varying N levels on the performance of hybrid maize, N accumulation, and N use efficiency at Khumaltar, Lalitpur, Nepal, during May to September in 2019 and 2020. The experiment consisted of 7 treatments: 6 levels of N (0, 90, 120, 150, 180, and 210 kg N ha−1) with application of P2O5 : K2O in 60 : 40 ha−1 and zero plots with no fertilizer application. The experimental was laid out in randomized complete block design with three replications. The results of the experiment revealed that the grain yield, N content, its uptake, efficiency, and economics of hybrid maize production were significantly (p ≤ 0.001) influenced by difference in N rates. Two years of pooled grain yield produced significantly (p ≤ 0.001) higher yield of 10.14 Mg ha−1 from application of 210 kg N ha−1 with benefit: cost ratio of 3.22. Likewise, two years of mean N concentrations in grain and stover were 13.13 and 5.32 g kg−1, respectively, with a total uptake of 117.3 kg ha−1. The data revealed that partitions of N in maize were 77.5% and 22.5% in grain and stover, respectively. The mean recovery efficiency, agronomic efficiency, and partial factor productivity of N in maize was found to be 48.9%, 20.9 kg kg−1, and 61.6 kg kg−1, respectively. Since additional N fertilizer had significant impact on maize productivity, it is advised to apply 210 kg N ha−1 under conditions of similar soil and ecology.
