INFLUENCE OF WIDE ROW SPACINGS AND INTERCROPS ON SUGARCANE GROWTH, YIELD AND JUICE QUALITY UNDER DRIP IRRIGATION IN NORTH-WEST KARNATAKA
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
A field experiment was conducted at KIAAR Sameerwadi, Tal: Mudhol, Dist: Bagalkot, Karnataka during 2013-14, to study the effect of different wider row spacings and intercrops on growth, yield and quality of sugarcane. The experiment consisted of three wide row spacings i.e. 1.2 m, 2.4 m (paired row) and 3.6 m (paired row) and three intercrops i.e. soybean, greenpea and onion. With respect to different row spacings, higher number of tillers was recorded in sugarcane at 1.2 m (83429, 64822 and 114076 ha-1 respectively) at different crop growth stages. Growing sugarcane at 1.2 m spacing recorded significantly higher plant height (142.22, 180.48 and 206.79 cm respectively) and dry matter production (0.22, 2.65 and 5.77 kg/ m2) throughout the crop growth. The number of millable canes and cane yield were also significantly higher at 1.2 m (134717 ha-1 and 111 t ha-1). Among different intercropping systems, the number of internodes was significantly higher in sugarcane + greenpea (13.93 and 30.91) at 210 DAP and at harvest. The taller sugarcane plants (144.34, 180.62 and 207.42 cm respectively) and higher dry matter production in sugarcane (0.20, 2.72 and 4.64 kg/m2 respectively) were noticed in greenpea intercropping throughout the plant growth. At 150 DAP, cane diameter and internodal length were significantly higher in sugarcane + greenpea (25.71 mm and 9.10 cm respectively).
