Abstract:

The present experiment entitled “Effect of different organic nutrient management practices on yield and yield attributes of sweet corn (Zea mays L. var. Saccharata)” was carried out at Indira Gandhi Krishi Vishwavidyalaya, Instructional cum Research Farm, Raipur (C.G.) during 2021 Rabi season. The main motto was to explore out the effect of different organic treatments of nutrient application on yield and yield attributes of sweet corn crop. Variety ‘Sugar-75’ of sweet corn was taken as the test crop for the experiment. The test crop was sown on 20th December 2021 and the research experiment comprising with 14 treatments of different organic nutrient management combinations with 3 replications in RBD design. The spacing assigned for the crop was 60 x 20 cm. The recommended nutrient dose was 100:60:40 kg ha-1 which was incorporated into soil according to various treatments through organic and inorganic sources.

Treatment consists of T1: 150% RDN through FYM, T2: 100% RDN through FYM, T3: 75% RDN through FYM, T4: 50% RDN through FYM, T5: Foliar spray of 20% cow urine at 15, 30, 45 and 60 DAS, T6: Beejamrit + ghanjeevamrit @ 250 kg ha-1 as basal + jeevamrit @ 500 l ha-1 at 15 days interval, T7: 75% RDN through FYM + foliar spray of 20% cow urine at 15,30,45 and 60 DAS, T8: 75% RDN through FYM + beejamrit + ghanjeevamrit @ 250 kg ha-1 as basal + jeevamrit @ 500 l ha-1 at 15 days interval, T9: 75% RDN through FYM + foliar spray of 20% cow urine at 15,30,45 and 60 DAS + beejamrit + ghanjeevamrit @ 250 kg ha-1 as basal + jeevamrit @ 500 l ha-1 at 15 days interval, T10: 50% RDN through FYM + foliar spray of 20% cow urine at 15,30,45 and 60 DAS, T11: 50% RDN through FYM + beejamrit + ghanjeevamrit @ 250 kg ha-1 as basal + jeevamrit @ 500 l ha-1 at 15 days interval, T12: 50% RDN through FYM + foliar spray of 20% cow urine at 15,30,45 and 60 DAS + beejamrit + ghanjeevamrit @ 250 kg ha-1 as basal + jeevamrit @ 500 l ha-1 at 15 days interval, T13: 100% RDN through inorganic, T14: Control.

The results of experiment on response of various organic nutrient management practices showed that number of grains row-1, number of rows cob-1, number of grains cob-1, green cob yield and fodder yield with the incorporation of 75% RDN through FYM + foliar spray of 20% cow urine at 15, 30, 45 and 60 DAS + beejamrit + ghanjeevamrit @ 250 kg ha-1 as basal + jeevamrit @ 500 l ha-1 at 15 days interval (T9) showed significantly maximum results among organic nutrient treatments although the treatment 100% RDN through inorganic (T13) significantly showed highest values as compared to all other treatments.
