Abstract

Cowpea responds to heavier application of phosphorus in Haryana soils since phosphorus plays an important role in nodulation, thus, the experiment comprising of five phosphorus levels viz., 0, 40, 60, 80 and 100 kg/ha and four levels of zinc, i.e., 0, 5, 10 and 15 kg/ha was conducted at Research Farm of the Department of Vegetable Science, CCS H.A.U, Hisar during spring-summer of 2015. The seed yield per plant (43.48 g), per plot (3.13 kg) and per hectare (21.74 q), germination percentage (90.53%), seed vigour index-I (3113.25) & II (49.73), protein content (26.76), net returns and benefit to cost ratio (2.04) were recorded maximum when the crop was supplied with phosphorus 60 kg coupled with zinc 10 kg/ha, however, the electrical conductivity (1.12 íScm−1seed−1) was recorded lowest at same dose of phosphorus and zinc due to slowest ageing process.
