Abstract
Baby corn cultivation can contribute in diversifying cropping pattern. Performance of baby corn variety (VL-78) recommended for north hill zone was evaluated under different fertility levels. The experiment was laid in randomized block design with three replications. Application of farm yard manure (FYM) at 6 T/ha in combination with 150% recommended dose of fertilizer (225N:90P2O5:60 K2O kg/ha) reveled maximum cob yield (without husk) of 20.60 q/ha associated with maximum number of cobs/plot (326). However application of FYM at 6 T/ha in combination with state recommended dose of Nitrogen: Phosphorus: Pottasium (N:P:K) at 90:60:40 kg/ha was statistically at par with the best treatment and gave a cob yield of 19.85 q/ha. Best treatment combination was also associated with maximum Total Soluble Sugars (T.S.S) content (11.20 Brix) in controlled pollinated cobs. Additional application of nutrients did not reveal any significant improvement in morphological characters. Application of 150% of Recommended Dose of Fertilizer (RDF) without FYM reveled increased cob length (10.90 cm), whereas, 125% of RDF resulted in maximum cob girth without husk (18.30 mm). Similar trend of enhanced green fodder yield (26.39 T/ha) was observed with application of 6 T/ha FYM + 150% of RDF). Cultivation of baby corn variety VL-78 under temperate conditions with an application of N:P:K at 90N:60P:40K, kg/ha in combination with 6 T/ha FYM revealed a maximum B:C ratio of 1:1.59.With 703 $/ha as cost of cultivation, the estimated gross returns from the cultivation practice were to the tune of 1825 $ giving a benefit of 1123 $/ha. Key words: Yield, nutrition, baby corn.
Highlights
Maize (Zea mays L) is the third most important cereal crop next to rice and wheat and has the highest production potential among the cereals
This study aims to evaluate the impact of FYM on yield and economics of baby corn cultivation
Significant variation was observed for cob yield without husk among various treatment combinations under investigation
Summary
Maize (Zea mays L) is the third most important cereal crop next to rice and wheat and has the highest production potential among the cereals. For diversification and value addition of maize as well as growth of food processing industries, recent development is of growing maize for vegetable purpose, which is commonly known as ‘baby corn’. It is a small young corn ear harvested at the stage of silk emergence. Young cob corn has been used by Chinese as vegetable for generations and this practice has spread to other Asian countries. It is used as ingredient in most food preparations. It has nutritive value similar to that of non- legume vegetable such as cauliflower
