Abstract:
A field experiment was conducted at the Navsari Agricultural University farm, Navsari (Gujarat) during kharif (Rice) and rabi (Sweet corn) season 2020 and 2021 to study the residual effect of iron management on chlorophyll and sugar content of rabi sweet corn in rice-sweet corn cropping sequence under South Gujarat condition. Total twelve treatments of different iron fertilizers along with Arbuscular mycorrhiza (AM) and Pseudomonas fluorescens biofertilizers replicated three times in Randomized Block Design in preceding kharif rice and rabi sweet corn crop nourished with recommended dose of fertilizer (120:60:60 NPK kg ha^-1) in rice-sweet corn cropping sequence under South Gujarat condition. Among the different treatments, residual effect of FeSO₄ @ 50 kg ha^-1 + AM + P. fluorescens Seedling treatment + Field application: 2L ha^-1 gave significantly higher content of chlorophyll content and sugar content of sweet corn during both the individual years and pooled analysis.
