Effect of FYM And Fe-Zn-S Supplementation on Yield and Quality of Multicut Forage Sorghum (Cv. SSG-3)
Subscribe/Renew Journal
Eighteen treatments comprising of combination of three levels of FYM (0, (F0), 10 (F1) and 20 (F2) t ha-1) and six nutrient management treatments [control (M0), Fe (M1), Zn (M2), S (M3), Fe+Zn (M4) and Fe+Zn+S (M5)] were tested in factorial randomized block design with three replications in field experiments conducted during Kharif and summer seasons of 2003 and 2004. Fe, Zn and S were applied @ 10, 5 and 40 kg ha-1 as FeSO4, ZnSO4 and gypsum, respectively. Initial available S, Fe and Zn contents in the soil were low. Yield of green forage and dry forage were increased by the treatments F2 and F1 (8.5 and 5.3 %, respectively) over treatment F0. The treatments M5 and M4 significantly increased the green fodder yield by 13.0 and 8.5 per cent, respectively, over that of M0 (731.5 q ha-1). The study of quality parameters viz., crude protein content, neutral detergent fiber and sugar content revealed that application of FYM at F1 and F2 as well as Fe-Zn-S treatments favourably influenced the quality parameters in comparison to their respective control.
