Abstract
Sugarcane responses to NPK application at 0-0-0, 150-0-0, 150-150 0, 1$0-150-150 kg/ha and planting geometry comprising 60, $0, 120 cm apart single, double and triple row strips, respecti- vely with 30 cm space between the cows of each strip were determi- ned on a sandy clay Joam soil, Among the three planting patterns, 90 cm apart paired row strip planting system on account of greater number of millable canes per unit area gave the highest cane yield of 128.58 tonnes/ha as against 115.98 and J11.72 tonnes‘ha for the 60 cm apart single rows and 120 cm apart triple row planting systems, respectively, As regards NPK rates, cane yield was increased by 20.6 tonnes/ba over the check with the application of 150 kg N afone, while the addition of 160k¢ P,0./ha alongwith N increased the cane yield further by 6.9 tonnes‘ha over N alone as against 7.1 tonnes/ha over NP with the application of )S0kg K,O; ha. The highest cane : top ratio of 12.27 was achieved in case of $0 cm apart paired row strip planting system compared to 9.59 for the 60 cm apart single row planting system. Similarly, the cane:top catio of 11,30 to 12.54 was recorded in fertilized treatments and the Jowest of 7.91 in check plots. Sucrese contents in cane were reduced significantly over the check with the application of N alone, While P and K in combination with N improved the sucrose contents in cane to the level of check,
