Abstract
A field experiment was conducted to know the influence of nipping and hormonal sprays on growth and seed yield of cowpea variety at the Organic Research Farm (HRF), Karguanji, Department of Seed Science and Technology, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (U.P.) India. In the present experiment, days to 50 percent flowering and no. of leaves at 30 DAS was not influenced by the combined effect of nipping and foliar sprays but the plant height, number of branches, number of leaves at 60 DAS and at harvest and dry matter production at various stages was influenced. The plant height was relatively more at all the stages of growth in non nipped plants with all the hormonal sprays GA350 ppm (N1H3), while number of leaves were more at 60 DAS and at harvest, number of branches per plant at all stage and dry matter at harvest were more in nipping at tendril stage combined to 1000 ppm lihocin spray (N2H2).The various seed yield traits were also higher in nipping at tendril stage and sprayed with growth hormones lihocin 1000 ppm (H2N2). The present investigation has indicated a relatively more beneficial influence of both nipping and hormonal spray on number of pods per plant, pod length, number of seeds per pod, pod wt. per plant, seed yield per plant and seed yield per hectare.
