STUDIES ON PLANTING SYSTEMS AND INTERCROPS ON GROWTH, YIELD AND ECONOMICS OF SURU SUGARCANE IN SOUTH MAHARASHTRA

摘要

Field experiment was conducted to study the planting systems and intercrops on growth, yield and economics of sum sugarcane (Co 94012) in South Maharashtra during 2006-07 to 2008-09 at Regional Sugarcane and Jaggery Research Station, Kolhapur. The studies indicated that, paired row planting at 75-150 cm recorded significantly higher cane yield ( 90.26 t ha~(-1)) over conventional planting at 90 cm row distance and paired row planting at 90-180 cm. Amongst the intercrop, groundnut intercropped with cane recorded significantly highest cane yield (89.43 t ha~(-1)) but at par with cabbage intercrop in sugarcane (87.88 t ha~(-1)). In respect of cane equivalent yield, both treatments of paired row planting at 75-150 cm and 90-180 cm, were found to be at par ( 98.36 and 98.44 t ha~(-1)) but they were significantly superior over conventional planting at 90 cm (92.371 ha~(-1)). The sugarcane intercropped with groundnut recorded significantly higher cane equivalent yield (102.67 t ha~(-1)) than other intercrops. The highest gross monitory returns, net returns and B : C ratio (Rs 116495/-, 27860/- and 1.32 respectively) was recorded in paired row planting of 75-150 cm, with intercrop of groundnut in sugarcane.
