An Impact of Drip Fertigation in Augmenting Yield and Economics of Sugarcane
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2019, Vol 9, Issue 4
Abstract
Principle of drip irrigation is to make most efficient and economic usage of limited water resources to increase water and nutrient use efficiency. The dream of green revolution has come true through proper use of water by drip irrigation. Sugarcane is a widely spaced longer duration crop in which enormous amount of water is being lost in the land outside root zone. If proper water management practices are available definitely it will increase the availability of water in the root zone and increase the yield of sugarcane and ultimately the economics of cane cultivation also increased. Field trial was conducted at Experimental farm, Department of Agronomy during January-December 2012 to find out the impact of drip fertigation on the yield and economic outputs of sugarcane. The trial was laid out in randomized block design with 3 Replications. There were altogether 10 nos. of treatments viz., T1-Control (no nutrient supply), T2-Farmers practice (275:150:150kgs of N, P2O5 and K2O per hectare), T3-50% P and K as basal and 100% N, 50%, P and 50% K as topdressing, T4-100% NPK through fertigation, T5-75% NPK as basal + 25% NPK through fertigation, T6-50% NPK as basal + 50% NPK through fertigation, T7-25% NPK as basal + 75% NPK through fertigation, T8-75% P and K as basal + 100% N, 25% P and K through fertigation, T9-50% P and K as basal + 100% N, 50% P and K through fertigation and T10-25% P and K as basal + 100% N, 75% P and K through fertigation. The investigation results clearly indicated that application of 75% P and K as basal + 100% N, 25% P and K through fertigation significantly enhanced the cane yield to the tune of 175 kg ha-1. Based on the results of the trials it can be concluded that application of 75% P and K as basal + 100% N, 25% P and K through fertigation efficiently augmented cane yield of 224.12 tons ha-1and boosted the economics of sugarcane cultivation by recording a benefit cost ratio of 4.09.
