Effect of crop geometry and nitrogen management on growth parameters, yield and quality parameters of baby corn (Zea mays L.)
Abstract
A field experiment was conducted to observe yield and quality of baby corn in split plot design with three treatments of crop geometry (30 cm x 20 cm, 30 cm x 15 cm and 30 cm x 10 cm) in main plots and five levels of nitrogen management (60, 75, 90, 105 kg/ha and 45 kg/ha+ 5 t FYM) in sub plots with three replications. Crop geometry 30 cm x 10 cm have more number of plants per unit area as compared to other crop geometry i.e 30 cm x 20 cm and 30 cm x 15 cm. Crop geometry have non significant effect on crop phenology stages of baby corn i.e days taken for knee high, tasseling and silking. However, plant height, leaf area index (LAI), cob yield, baby corn yield, fodder yield, dry matter accumulation and total nitrogen uptake in 30 cm x 10 cm crop geometry were significantly higher than all other geometry treatments. Length of baby corn, weight of cob and baby corn weight were significantly higher in 30 cm x 20 cm crop geometry. Crude protein content of baby corn was significantly higher in 30 cm x 20 cm than other treatments. Growth and yield parameters like plant height, leaf area index, dry matter accumulation, cob yield, baby corn yield, total nitrogen, phosphorus and potassium uptake, cob weight, number of cobs per plant, baby corn length, girth, weight of baby corn were significantly improved by nitrogen application up to 105 kg N/ha. Significant increase in quality parameters such as crude protein, total sugar and starch of baby corn was in 105 kg N/ha treatment, but non significant effect on cob texture, TSS and total solids.
