Abstract
An experiment was conducted for two consecutive years at Main Sugarcane Research Station, Navsari Agricultural University, Navsari, Gujarat, India during 2021-22 and 2022-23 to study the effect of age of single eye bud settling and nutrient management influence on cane yield and nutrient acquisition of sugarcane (Saccharum hy. sp.) under south Gujarat condition. The experiment comprised of twelve treatments which was laid out in factorial randomized block design with three replications. Significantly higher cane yield (86.44, 89.79 and 88.11 t/ha) was recorded with treatment of 30 days old settling. Nutrient management practices have marked effect on cane yield and treatment recommended dose and schedule of nutrient applications recorded significantly highest cane yield (85.17, 84.38 and 84.78 t/ha) during both the years and in pooled analysis, respectively. It was remained at par with treatments RDN + RDK in four splits and RDN + RDK in three splits in both years and in case of pooled analysis only treatment RDN + RDK in four splits remained on par. Maximum K balance was recorded in case of treatment combinations 20 Days old settling+ Recommended dose and schedule of nutrient applications which was followed by 30 Days old settling+ Recommended dose and schedule of nutrient applications (+213.99) and (+209.26) kg/ha, where nitrogen and phosphorus balance was found negative under all treatment combinations.
