Studies on effect of phosphorus levels, time of it’s application along with arbuscular mycorrhiza on yield, quality and phosphorus use efficiency in sugarcane

Abstract

A field experiment was conducted in clayey textured soil at N.M. College of Agriculture, Research farm, Navsari Agril., University, Navsari, Gujarat during 2017-18 and 2018-19 with the view to evaluate an appropriate phosphorus level (100 and 75% of RD of P2O5), determining the time of P2O5 application (Basal and 50-50% Split), with and without use of biofertilizer as arbuscular mycorrhiza (AM) on the yield, quality and Phosphorus use efficiency (PUE) of sugarcane. The pooled data of two seasons indicated that sugarcane crop responded significantly with phosphorus management. Significantly highest yield attributes, cane, green top and quality of juice were recorded with 100 percent RD of P2O5, splitting of phosphorus and with the use of AM in Sugarcane. Similar significant results in terms of P content in juice and sugar yield were recorded. The Agronomic phosphorus use efficiency and partial factor productivity were enhanced significantly with splitting of P2O5 and AM in sugarcane.
