Abstract:
Experiments were conducted during the year 2020-21 and 2021-22 in Rabi season at the research farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The field technique for conducting soil test crop response correlation studies, as described by Ramamoorthy et al. (1967) was followed. The treatments consisted of various combinations of nitrogen, phosphorous and potassium fertilizers at different levels of farmyard manure. It was observed that fertilizer nitrogen had the highest effect on improving the total sugar, starch and protein contents of sweet corn, which was followed by fertilizer phosphorous and potassium. Farmyard manure used in combination with the fertilizers also increased the total sugar and starch contents. However, its effect was found less in the improvement of protein contents of sweet corn. The balanced fertilization obtained was 120:60:60 kg ha^-1 of N, P, K for total sugar and starch contents and 180:60:60 kg ha^-1 of N, P, K at 10 t ha^-1 FYM for protein contents.
