Effect of foliar application of potash and micronutrients on growth and yield attributes of groundnut

Abstract

A field experiment was conducted during summer season of 2012 on medium black soil to study the
effect of foliar application of potash and micronutrients on growth and yield attributes of groundnut.
The experiment consisted of six treatments (control, K @ 0.5%, Fe @ 0.5%, Zn @ 0.5%, B @ 0.2% and
K @ 0.5% + Fe @ 0.5% + Zn @ 0.5% + B @ 0.2% at 40 DAS as foliar spray) thereby making six
treatments tested in randomized block design with four replications. Results indicated that the
application K @ 0.5% + Fe @ 0.5% + Zn @ 0.5% + B @ 0.2% foliar spray at 40 DAS results is significantly
higher the plant height, number of branches per plant, dry matter at 45 and 75 DAS, number of
nodules per plant, pod weight, 100 kernel weight, shelling per cent, pod and haulm yield. However,
day to 50% flowering, CGR, RGR and test weight did not significantly influenced by various foliar
applications.
