摘要：The experiment comprised of 10 treatments, such as T 0 : Control condition; T 1 : All chemical fertilizer as recommended dose; T 2 : Cowdung as recommended dose; T 3 : Compost as recommended dose; T 4 : ½ Cowdung + ½ Compost; T 5 : Cowdung + Compost; T 6 : Cowdung + ½ Chemical fertilizer; T 7 : Compost + ½ Chemical fertilizer; T 8 : Cowdung + Compost +½ Chemical fertilizer and T 9 : ½ Cowdung + ½ Compost + ½ Chemical fertilizer. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different growth characters and yield were recorded. Among the treatments all chemical fertilizers as recommended dose (T 1 ) and cowdung + compost + ½ chemical fertilizer (T 8 ) were found superior considering all yield contributing characters and yield. At 30 (Days after Sowing) DAS, the longest plant was recorded from T 8 (27.93 cm), while the shortest plant was found in T 0 (23.13 cm). At 50, 70, 90 DAS and harvest the longest plant was recorded from T 1 (52.13 cm, 82.13 cm, 85.93 cm and 95.21 cm), whereas the shortest plant was obtained from T 0 (41.14 cm, 65.84 cm, 70.77 cm and 76.00 cm). At 30, 50, 70, 90 DAS and harvest the maximum number of tillers hill -1 was recorded from T 1 (2.00, 5.64, 6.93, 6.15 and 5.78), whereas the minimum number was found in T 0 (1.33, 2.87, 4.20, 3.94 and 3.72). The longest spike (19.86 cm), maximum number of spikelets spikes -1 (20.33), maximum number of filled grains spike -1 (34.00), highest grain yield (3.71 t ha -1 ) and highest straw yield (5.78 t ha -1 ) was attained from T 1 and the shortest spike (14.33 cm), minimum number of spikelets spikes -1 (14.18), minimum number of filled grains spike -1 (21.53), lowest grain yield (2.06 t ha -1 ) and lowest straw yield (4.49 t ha -1 ) was recorded from T 0 .
