Biofortification of zinc with different phosphorous sources on growth and yield of groundnut (Arachis hypogaea L.)

Abstract

The present experiment was carried out at the Central Research Farm, SHUATS, Allahabad during Kharif 2018. The experiment was consisting of two methods of zinc application soil (25kg ha-1) and foliar (0.25%) and different sources of phosphorous namely DAP, SSP and PROM (Phosphorus Rich Organic Manure) (P- 16.5%) laid out in Randomized block design with ten treatment combinations and the number of replications was three. Maximum Kernel yield was recorded in Treatment T7 (DAP + Zinc 25 kgha-1 application + Zinc 0.25% Foliar application) and treatment T8 (SSP + Zinc 25 kgha-1 application + Zinc 0.25% Foliar application) however, treatment T9 (SSP + Zinc 25 kgha-1 application + Zinc 0.25% Foliar application) is statistically at par to the height value.
