 ABSTRACT

A field experiment was conducted on sorghum during kharif season of 2012, 2013 and 2014 for consecutive three years at Agricultural Research Station, S.K. Rajasthan Agricultural University, Bikaner to study the effect of different water regimes on growth, yield and fodder quality of forages sorghum cultivars. The treatments consist of three levels of water regime i.e., four irrigation (in all water regimes) each of   50, 40 and 30 mm in sufficient, limited  and deficit water regime, respectively and four sorghum cultivars viz. PC-23, MFSH-4, SSG & COFS-29. The experiment was laid out in split plot design with four replications. The results showed that maximum plant height (138 cm); Leaf : Stem (L:S) ratio (0.52); green fodder (231  q/ha) and dry matter (37.15 q/ha) yield; and  production efficiency of green fodder (184.90 kg/ha-day) and dry matter (29.72 kg/ha-day) yield; crude protein percent (9.88%) and crude protein yield (3.67 q/ha) were recorded with sufficient water regime. The superiority of the water regime of 50 mm depth per irrigation (sufficient) was further depicted by the highest net returns of Rs. 26060/ha in fodder sorghum. However, values for all above parameters were at par with limited water regime (40 mm depth per irrigation). Highest water use efficiency (8.88 kg/ha-mm) was recorded with limited water regime, closely followed by sufficient water regime (8.87 kg/ha-mm). Further, sorghum cultivar MFSH-4 recorded highest plant height (141 cm); L:S ratio (0.53); green fodder (229.61 q/ha) and dry matter (38.71 q/ha) yield; production efficiency of green fodder (183.69 kg/ha-day) and dry matter (30.54 kg/ha-day) yield; crude protein percent (10.23 %) as well as yield (3.90 q/ha); water use efficiency (10.07 kg/ha-mm) and net returns (Rs. 30430/ha).
