Effect of depth of root pruning and coppicing height of Gliricidia sepium on growth and yield of rabi sorghum in alley cropping system in Northern dry zone of Karnataka.

摘要

Among depths of root pruning, pruning at 45 cm depth found beneficial in higher plant height, length and width of earhead of rabi sorghum. The grain and stover yield of rabi sorghum were significantly maximum in 45 cm depth of root pruning (1047.7 and 1677.5 kg ha-1, respectively). Among coppice height, coppicing at 20 cm height noticed higher growth and yield attributes. Significantly maximum grain (1019.0 kg ha-1) and stover yield (1529.5 kg ha-1) were recorded by 20 cm coppicing height and also same treatments were shown higher net returns (7825.50 ha-1) and B:C ratio (2.25).
