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 .

Ethambutol is one of the important first line drugs in the treatment of tuberculosis (TB). It is also commonly employed in the treatment of non-tuberculous mycobacterial infection. ETB may occasionally cause ocular toxicity but evidence suggests that it is as safe as or safer than the other standard anti-TB drugs provided proper precautions are taken when prescribing the drug. 5
