Abstract
The animal feed nutritional value is dependent on the feed chemical composition and which could be affected by sulfur fertilization and irrigation regimes. Therefore, the present study was formulated to evaluate the effect of sulfur fertilization and irrigation regimes on fodder sorghum in semi-arid region. A two-year field experiment (2016/2017) was conducted on multi-cut hybrid sorghum with three moisture regimes (60 and 120 Cumulative Pan Evaporation (CPE), and no irrigation) and three sulfur (S) levels (0, 15 and 30 kg/ha S) as sub-plot treatment in split-plot design replicated thrice. Statistical analysis of the data revealed that individually irrigation scheduling at 60 CPE and sulfur application at 30 kg/ha resulted maximum plant height, leaf area index and number of tillers. The application of 30 kg/ha S observed with higher total green fodder yield which was 20.1% in 2016 and 16.8% more than control in 2017 and nearly, similar results were also obtained in relation to dry matter yield. Sulfur fertilization and irrigation at 60 CPE showed 39.5% mean reduction in hydrocyanic acid and the average crude protein of 10.5% and in vitro dry matter digestibility of 55.5% at 1st cut was recorded. Application of S and irrigation regimes improved the nitrogen and sulfur concentration in fodder. In conclusion, the application of sulfur @ 30 kg/ha through any sulfur source could be considered as the potential sulfur fertilizer in improving the injurious effects of water deficit condition of hybrid multi-cut fodder sorghum through alterations in nutrient uptake, yield and quality.
