Production of baby corn influenced by Nitrogen application and crop geometry: A review

Abstract

Baby corn is a short-term crop, with an unfertilized maize ear which is harvested within 2-3 days of silk emergence of the plant. It is a newly introduced crop in India and being a high-value and short-span crop (50-60 days) it has a good perspective in improving the financial status of the farmers. Advancement and standardization of agronomic practices are required before familiarizing the crop among farmers. Among different agro-techniques, crop geometry and Nitrogen application are considered as one of the most important factors to the production yield of crop. Nitrogen deficiency is a broad phenomenon its proper management is mandatory from a financial and environmental view. It is concluded in studies that the yield of crop increase with an increase in N rates but the optimum dose is dependent upon plant density. However response of the N application was different for quality and yield attributes. Plant density is another major aspect of the performance of baby corn. It is reported that quality attributes were much better in wider spacing due to a decrease in plant density. It is also reported that narrow spacing and increase in N application concurrently increase the yield attributes. More research studies are needed on the combined approach (Plant geometry and N application) in the baby corn can intensify yield and quality in baby corn. Optimization of both attributes is depended on location and season. However, economically effective and user’s friendly precision tools may be a feasible option for getting the real farm situation.
