 ABSTRACT

A field experiment was conducted in clayey soils 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 recommended dose of   P2O5), determining the time of P2O5 application (basal and split) and use of biofertilizer as arbuscular mycorrhiza (AM) (with and without) on the growth, development and yield of sugarcane. The pooled data of two seasons indicated that sugarcane crop responded significantly with phosphorus management. When crop fertilized with P level of 100 percent RD of P2O5 responded significantly at 180 days after planting (DAP) and at harvest, at harvest cane girth, average cane weight, number of millable canes/ha (NMC/ha), periodical dry matter yield (DMY), mean crop and relative growth rate (CGR and RGR) and cane, green top yield of sugarcane. The splitting of phosphorus (50 % P2O5 at the time of planting and 50 % at the time of earthing up) also recorded significant results at harvest on plant height, NMC/ha, average cane weight, periodical DMY, CGR and RGR and cane, green top yield of sugarcane. Similarly an application of AM biofertilizer recorded significant results in terms of plant height, NMC/ha, cane weight, DMY at harvest, CGR and RGR and yield in sugarcane. In sugarcane crop splitting of phosphorus along with AM responded significantly in terms of plant population at harvest, DMY and growth analysis as well as yield in south Gujarat condition.
