Effect of NPK on seed-cotton yield and ancillary characters of desi cotton (Gossypium arboreum L.)



Effect of NPK on seed-cotton yield and ancillary characters of desi cotton (Gossypium arboreum L.)



Journal of Research, Punjab Agricultural University 14(1): 18-22



In field experiments in 1969-71 cotton G27 was given combinations of 0, 45 or 90 kg N/ha, 0, 25 or 50 kg P2O5/ha and 0, 25 or 50 kg K2O/ha. N application significantly increased seed-cotton yield from 0.95 t/ha with no N application to 1.08 t/ha with 90 kg N/ha. N application also significantly increased number of bolls/plant and plant ht. K application also increased seed-cotton yield from 0.97 t/ha with no K application to 1.03 t/ha with 25 kg K/ha.
