Abstract:
The present investigation was conducted during 2016-18 on an Inceptisol of Rahuri, Maharashtra to evaluate the effect of cogenerated bagasse ash on growth, yield and quality of sugarcane. The experiment laid out in randomized block design with 3 replications and comprised of 9 treatments. The results showed that growth parameters and yield of sugarcane increased significantly with increasing rates of potassium through cogenerated bagasse ash over the control. The application of 6.62 t ha^-1 cogenerated bagasse ash along with recommended dose of N, P₂O₅ (340 and 170kg ha^-1) through chemical fertilizers and 20 t ha^-1 FYM is recommended for getting higher number of millable canes (86.41 x 10³ ha^-1), cane yield (146.71 t ha^-1) and commercial cane sugar yield (19.58 t ha^-1). These results clearly indicated that the cogenerated bagasse ash can be used as a substitute for potash fertilizer in particular and as a source of carbon as well as other source of plant nutrients in general. The addition of 150% recommended dose of potassium through cogenerated bagasse ash (6.62 t ha^-1) has substituted 100% recommended dose of potassium through inorganic fertilizer (Muriate of Potash) requirement of sugarcane crop.
