Abstract: Experimentation at twenty farmer’s field of tribal area of Mandla district of Madhya Pradesh during Kharif 2015-16 considering zinc variability in soil as low, medium and high, and Zn levels through ZnSO4 7H2O in a RBD. The soils of selected sites wer clayey, alkaline in pH, organic carbon varied from less to marginal and varied in available Zn from 0.12 to 2.17 mg kg-1. The rice MTU-1010 seed was sown @ 80 kg ha-1 with recommended practices and harvested at maturity (120 DAS).
Significant effects were noted on growth and yield components yield content and uptake by rice: plant height in S-12 (36.73 cm), no. of tillers/ hill (9.79) in S-17, no. grains/panicle varied from 53.00 (S-6) and to 71.33 (S-7) and test weight (24.25 g) in soil S-7. Yield was recorded S-9 (4.75 t/ha) which was at par with S-14 (4.47 t ha-1). Highest tillers per hill-1 (8.15) were noted with basal application @ 8 kg Zn ha-1 but similar with (8.03) just 6 kg and low with no zinc. It had also increased the yield (3.57 t ha-1) but at par with 6.0 kg Zn ha-1 (3.44 t ha-1). Zinc content and its uptake varied and recorded more in 8.0 kg Zn ha-1 but equal to 6.kg Zn ha-1.
