EFFECT OF PLANT POPULATION AND FERTILITY LEVELS ON GROWTH AND NPK UPTAKE BY SWEET CORN (ZEA MAYS L.) CULTIVARS
2014
MASSEY, J.X. | GAUR, B.L.
A field experiment was conducted during kharif 2001 and 2002 to study the effect of plant population and fertility levels on growth and NPK uptake by sweet corn (Zea mays L.) cultivars. Test cultivars did not significantly differ in respect of growth parameters, yield and nutrient uptake. Plant population at 55 thousand/ha gave significantly higher dry matter accumulation at harvest. However, successive increase in plant population densities from 55 thousand to 75 thousand/ha recorded significantly higher plant height, number of leaves per plant at tasseling stage, leaf area, leaf area index, green cob yield and NPK uptake by crop were recorded with the application of fertilizer up to 90 kg N + 45 kg P2O5/ha.
