Abstract:
A field experiment was conducted in sandy loam soils of Tamil Nadu Agricultural University, Coimbatore, during Rabi and summer seasons of 2016-17 and 2017-18 to evaluate the influence of crop geometry and N and Fe nutrition on quality of babycorn. Experiment was conducted with five crop geometry levels viz., 60 × 20cm (S₁), 60 × 15cm (S₂), 45 × 20cm (S₃), 45 × 15cm (S₄), 30 × 30cm (S₅) in main-plot and four nutrient levels such as 100% recommended dose of nitrogen (RDN) (N₁), 100% RDN fb FeSO₄ foliar spray @ 1% at 30 and 45 DAS (N₂), 125% RDN (N₃), 125% RDN fb FeSO₄ foliar spray @ 1% at 30 and 45 DAS (N₄) in sub-plot in split-plot design. Results revealed that crop geometry did not show any significant influence on the quality parameters of babycorn and its fodder excepting starch content and sugar content of babycorn. With increase in fertilization levels, quality parameters of babycorn except vitamin A and C content also increased up to the level of N₄ and were on par with N₃. The interaction effect was not statistically pronounced on the quality parameters of babycorn.
