POLY4 Positively Improves the Growth, Fodder Yield and Quality of Oat (Avena sativa L.) in Semi-Arid Tropics of Central India

A study was carried out to examine the effects of different potassium fertilizer sources on growth, fodder yield and quality at Research Farm, Rani Lakshmi Bai Central Agricultural University, Jhansi, Uttar Pradesh. The experiment conducted under semi-arid climatic conditions in a simple Randomized Block Design (RBD) with ten treatments (control, 100% NP, recommended dose (RDK) through MOP, RDK SOP, POLY4, 75% RDK+ 1% foliar spray (30 days after sowing 30 harvest) schoenite schoenite, MOP + KSB (potassium solubilizer bacteria, Seed treatment), alone (Seed treatment) three replications. Results showed that application POLY4 recorded significantly highest growth contributing parameters, which is beneficially resulted increased green (159%) as compared control. However, it par schoenite. parameters viz. CP, ADF, NDF were also remarkably improved RDK+1% oat crop. results imply farmers may apply achieve good higher sandy clay loam soil for production.
