Studies on the effect of nutrient management practices on the growth and yield of sweet corn

A field experiment was conducted during summer, 2015 to study the response of sweet corn (Zea mays L) to various nutrient management practices, laid out in randomized block design with three replications that comprises of viz., T¬1 Control, T2 RDF alone (135 : 62.5 : 50) kg NPK ha-1, T3 RDF + Micro nutrient mixture @ 20 kg ha-1,T4 RDF + Soil application of humic acid @ 50 kg ha-1, T5 125% RDF alone, T6 125% RDF + Micro nutrient mixture @ 20 kg ha-1,T7 125% RDF + Soil application of humic acid @ 50 kg ha-1, T8 RDF + Micro nutrient mixture @ 20 kg ha 1+ soil application of humic acid @ 50 kg ha-1, T9 125 % RDF + micronutrient mixture @ 20 kg ha-1+ soil application of humic acid @ 50 kg ha-1. It was observed that growth and yield of sweet corn was significantly high in the treatment T9 (125 % RDF + micronutrient mixture @ 20 kg ha_1+ soil application of humic acid @ 50 kg ha-1). The results also revealed that highest green cob yield of 6628 kg ha-1 was recorded in treatmentand it was superior than other treatments.
