    Effect of integrated nutrient management on production of sugarcane (Saccharum officinarum) and soil properties
    (CCSHAU, 2017) Joginder Kumar; Vijay Kumar
    An experiment was conducted during 2016-17 at Regional Research Station, Karnal of CCS Haryana Agricultural University to study the effect of integrated nutrient management on effect of different treatments on juice quality parameters, physico-chemical properties of soil, uptake of nutrient by sugarcane crop and economics of sugarcane production. The experiment comprised of 10 treatments viz. T1: Control (No fertilizer),T2: 50% recommended dose (RD) of NPK,T3: Recommended dose (RD) of NPK,T4: Soil test based NPK,T5: FYM@15t/ha + 50% RD NPK,T6: FYM@15t/ha + 100% RD NPK,T7: FYM@15t/ha + NPK based on STV,T8: FYM@10t/ha + Bio fertilizers (BF) +50%RD NPK,T9: FYM@10t/ha+BF+100% RD NPK,T10: FYM@10t/ha + BF+ STV NPK. The design of the plot was randomized block design (RBD). The application of 100% RD NPK significantly increased the cane yield and yield attributes (germination percentage (40.74%), cane girth (2.44cm), cane weight (0.78kg/cane), cane length (2.67m) and NMC (97223). The application of FYM@15t/ha+100% RD NPK had increased the cane yield (93.23t/ha) and yield attributes parameters ( germination percentage 44.91%, cane girth 2.73cm ,cane weight 0.92kg/ha, cane length 2.97m, NMC 101393). However, the application of FYM@10t/ha+ BF+100%RD NPK increased the cane yield and yield attributes (germination percentage 43.99% , cane girth 2.64cm, cane weight 0.88kg/ha, cane length 2.91m, NMC 99986). The application of 100% RD NPK and STV based NPK gave the equal result in Juice quality parameter (Brix%, Sucrose %, CCS% and Sugar yield), available nutrient in soil and uptake of N,P,K by sugarcane plant. The application of FYM@15t/ha+100% RD NPK at par the Juice quality parameter (Brix 20.9%, Sucrose 18.53%, CCS12.77% and Sugar yield 21.36t/ha). The application of FYM@15t/ha+100% RD NPK had increased the available N (191kg/ha), P (11.00kg/ha), K (186.00 kg/ha) and CEC (16.61 cmol(p+)/kg). Application of FYM@10t/ha+BF+100% RD NPK had increased N 186 kg/ha, P 10.50 kg/ha, K 184.0 kg/ha and CEC, 15.80 cmol(p+)/kg over the 100% RD NPK. The application of FYM@15t/ha+100% RD NPK had increased the uptake of N 696.80kg/ha, P 63.35 kg/ha, K 424.80 kg/ha by sugarcane plant over control. The application of 100% RD NPK increased the net return to the turn of Rs. 128017 and the B: C of 1.15. The application of FYM@ 15t/ha+100% RD NPK achieved the maximum net return of Rs. 176684 and B: C ratio of 1.5. Cultivation of sugarcane must be done through judicious use of fertilizers since application of fertilizer affects both quality and quantity. Absence of nutrients or application of unrecomended dose of fertilizer resulting in cane yield and quality losses. The application of 50% RD NPK did not achieve the cane yield and juice quality as obtained with the application of 100% RD NPK. The application of 100% RD fertilizer achieve the similar yield as achieved by the application of STV based NPK. The application of farm yard manure (FYM) to achieve the maximum yield. Sugarcane grown in soi low in organic carbon in combination of recommended dose of NPK may increase the cane yield and sugar yield. The application of FYM@ 15t/ha+50% RD NPK achieved the similar cane yield and juice quality as achieved by the application of 100% RD NPK. In this experiment FYM@15t/ha+100% RD NPK further increase the cane yield and sugar yield over the application of 100% RD NPK. The application of biofertilzer has importance for biological nitrogen fixation. So, combination of bio fertilizers with organic manure and NPK fertilizer also achieve the higher yield over the 100% RD NPK. The application of FYM@10t/ha+ bio fertilizer (Azotobacter + PSB) +100% Rd NPK save significantly higher cane yield and super production over application of 100% RD NPK alone.
