Abstract:

An investigation was conducted in rabi season of 2013-14to work out the economics of various treatment combinations in barley crop. The experiment was laid out in split plot design with four levels of nitrogen (0, 20, 40, and 60 kg N ha-1) and three time of application (½ at the time of sowing and ½ after first irrigation, 1/3 at sowing and 2/3 after first irrigation, 1/3 at sowing, 1/3 after first irrigation and 1/3 after second irrigation) with three replications. Nitrogen level (60 kgha-1) and Time of application (1/3 at sowing and 2/3 after first irrigation) treatment was found significantly superior over rest of the treatments in yield attributing characters and yield i.e. No. of spikelets spike-1, Length of spike (cm), No. of grains spike-1, Test weight (g), Grain and Straw yield (qha-1) and Harvest index (%). Treatment N3(60 kgha-1) increases significantly over other rest treatments and was found superior with No. of spikelets spike-1 (9.48), Length of spike (8.94 cm), No. of grains spike-1 (26.88), Test weight (42.69 g), grain yield (24.52 qha-1) and straw yield (37.60 qha-1) under main plot treatments. Treatment T2 (1/3 at sowing and 1/3 after first irrigation and 1/3 after second irrigation) was found best with No. of spikelets spike-1 (8.90), Length of spike (8.11 cm), No. of grains spike-1 (24.09), Test weight (41.90 g), grain yield (21.96 qha-1) and straw yield (32.46 qha-1) as compared to other treatments and being at par with Treatment T3 (1/3 at sowing and 1/3 after first irrigation and 1/3 after second irrigation) in all aspects of yield attributes and yield. Highest net return of Rs. 23593.88 ha-1 was recorded with N3T2 (60 kg N ha-1) + Time of application (1/3 at sowing and 2/3 after first irrigation) fb Rs. 19836.88 ha-1with N3T3 (60 kg N ha-1) + Time of application (1/3 at sowing, 1/3 after first irrigation and 1/3 after second irrigation) treatment combination. The b-c ratio (Rs. 1.04) was observed maximum under the treatment combination of N3T2fb (Rs. 0.87) N3T3 treatment combination.
