This paper documents the effects of crop geometry and nitrogen levels on baby corn maize crop. A field experiment was carried out during winter (rabi) season of 2019 at Instructional cum
Research Farm, IGKV, Raipur, in split plot design with three replications. It was conducted to study the effect of crop geometry and nitrogen levels on growth, yield attributes of baby corn G5414. The treatments involve four crop geometries and three nitrogen levels. Crop geometries are 30 x 20cm, 40 x 20cm, 50 x 20 cm, 60 x 20cm and nitrogen levels are 75,100,125 kg N/ha. Result illustrated that number of leaves, leaf area index, stem girth , crop growth rate , number of young cobs plant-1 ,length of cob with and with out husk ,diameter of cob with and with out husk N content in cob and fodder was found significantly higher in planting geometry of 60 x 20 cm and all these characters were also found superior under treatments receiving 125 kg N/ha. Plant height and fodder yield was found significantly higher in 30 x 20cm. cob yield and harvest index was observed in planting geometry of 50 x 20 cm and at the application of 125 kg N/ha. Planting geometry of 50 x 20 cm (1,00,000 plants/ha) with 125 kg N/ha gives highest gross returns (Rs. 198576/ha), net returns (Rs. 154337/ha) and B:C ratio (2.5). Further, the spacing of 50 x 20cm application of nitrogen i.e 125 N kg ha-1 was found to be economical as it gave highest monetary benefits and B:C ratio.
Key words: Baby corn, crop geometry, nitrogen levels and fodder yield
