Abstract

A field experiment was conducted during rainy (kharif) seasons of 2013 and 2014 to find out the impact of tillage, crop residue and sulphur fertilization on growth, productivity and economics of pearl millet [Pennisetum glaucum (L.) R. Br. Emend. Stuntz.]. Five tillage and residue management practices i.e. conventional tillage (CT) with 0, 2 and 4 t/ha crop residue; zero tillage (ZT) with 2 and 4 t/ha crop residue were allocated to main plots and four sulphur levels (0, 15, 30 and 45 kg S/ha) in sub-plots. Conventional tillage with 4 t/ha residue gave significantly higher growth parameters (plant height, dry-matter accumulation and leaf area index) and SPAD value at various growth stages of crop. This treatment also improved yield attributes of pearl millet, viz. length of earhead, grains weight/earhead and 1,000-grains weight and produced 24.3 and 16.6% higher grain and stover yields over CT without residue, respectively. The highest net returns (31.5 ×103 /ha) and Benefit: cost ratio (1.69) were computed in ZT with 4 and 2 t/ha residue, respectively. Results also revealed that increasing levels of sulphur up to 30 kg/ha significantly increased growth parameters, SPAD value, yield attributes and yield of pearl millet as compared to control. Application of 30 kg S/ha resulted in 15.6 and 20.4% higher grain and protein yield over the control, respectively. Furthermore, the highest net returns (31.5 ×103 /ha) and benefit: cost ratio (1.50) were also fetched with 30 kg S/ha.
