Abstract

A study on the effects of NPK, zinc, and iron on soil health and yield parameters of green gram was carried out in the crop research farm, department of Soil Science and Agricultural Chemistry at SHUATS, Prayagraj, from May to July of 2023. Nine treatments were used in a randomised block design (RBD) experiment, each of which was replicated three times. During the sowing process, NPK fertiliser, zinc, and iron were added to the soil. The recommended doses of zinc and iron are 15 kg ha-1 and 20 kg ha-1, respectively, and of NPK are 25:50:25. The plant height, No. of pods plant-1, No. of seeds pod-1, grain yield, water holding capacity, % pore space, % organic carbon, soil EC, available nitrogen, available potassium, and available iron were found to be significant and was recorded maximum in T9 - [[NPK @100% + Zn @100% + Fe @100%]. Bulk density, particle density and soil pH were recorded maximum in T1- [NPK @ 0 % + Zn @ 0 %+ Fe @ 0%]. Available phosphorous was recorded maximum in T7- [NPK @100% + Zn @0% + Fe @100%] whereas available zinc was recorded maximum in T3- [NPK @ 0% + Zn @ 100% + Fe @100%]. The present study reported that the Zinc and Iron on Soil Health and Yield Parameters of Green gram (Vigna radiata L.) var. SML-668 fertilizes doses of NPK + Zinc + Iron gave positive test values arching desired yield targets of greengram situations for Prayagraj region.
