Effect of planting time, fertility level and plant population on development, yield, nutrient uptake and quality of winter popcorn (Zea mays everta Sturt) under late sown condition

Effect of Planting Time, Fertility Level and Plant Population on Development, Yield, Nutrient Uptake and Quality of Winter Popco A popcorn (Zea mays everta Sturt.) composite variety, namely V.L. Amber was assessed for their potential role as winter crop in the management at Agricultural Research Farm of BHU, Varanasi, India, under late sown condition of 2009-10 and 2010-11, respectively. The three date of sowing i.e. 15th December, 30th December and 15th January with three plant population (60,000, 80,000 and 100,000 plants/ha) in main plots and three fertility levels (N100P50K50, N150P65K65, N200P85K85 kg/ha) in sub plot laid out in split plot design with three replications. The sandy clay loam in texture with pH 7.6, 0.35 % organic carbon and 183 kg available nitrogen, 21.02 and 228 kg ha-1 of available phosphorus and potassium, respectively were determined to find out the development, yield, nutrient uptake and quality of winter popcorn. n (Zea mays everta Sturt) under Late Sown Condition | Effect of planting time fertility level and plant population on development yield nutrient uptake and quality of winter popcorn Zea mays everta Sturt under late sown condition Int.J.Curr.Microbiol.App.Sci 2017 6 2 1187-1193 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 2 2017 pp. 1187-1193 Journal homepage http www.ijcmas.com Original Research Article http dx.doi.org 10.20546 ijcmas.2017.602.134 Effect of Planting Time Fertility Level and Plant Population on Development Yield Nutrient Uptake and Quality of Winter Popcorn Zea mays everta Sturt under Late Sown Condition S.K.
