Yield and nutrient uptake of baby corn (Zea mays L.) Genotypes as influenced by crop geometry and fertility levels

Abstract

A field experiment was conducted to study the effect of crop geometry and fertility levels on the yield and nutrient uptake of baby corn (Zea mays L.) genotypes. The experiment was laid out in split plot design with main plot factor comprising of 4 treatment combinations of crop geometry(S) and fertility levels(F) viz. S1F1(65cm × 16 cm, RDF), S1F2(65cm × 16 cm, 150%RDF), S2F1(65cm × 12 cm, RDF) and S2F2,(65cm × 12 cm, 150%RDF) and sub plot factor comprising of 2 baby corn genotypes (G) viz. G1(BC-18K-ZIII-1) and G2(BC-18K-ZIII-2). The combination of (S1F2)G2 recorded the maximum first baby cob yield and baby corn yield. The combination of (S1F2)G1 recorded maximum harvest index. The total N and K uptake was significantly higher for S2, F2 and G2 as compared to S1, F1 and G1, respectively. The P and K uptake for cob husk was maximum with the combination of (S2F2)G2.
