“…Zinc is one of the important Micro-nutrient which is essential for plant growth. Zn deficiency is the most widespread micronutrient disorder in lowland rice and application of Zn along with NPK fertilizer increases the grain yield dramatically in most cases (Fageria et al, 2011;Singh et al, 2011). Plant root absorbs zinc as ion (Zn ++ ) and as component of synthetic and natural molecular complexes can also enter the plant system directly through leaves.…”

“…Applying Zn fertilizers in the soil also increases dry matter, grain yield and grain Zn concentration in rice (Shehu and Jamala 2010;Fageria et al 2011). Sowing rice seeds with high Zn content (mixing seed in Zn powder) was found to result in a rapid and better germination, greater root length and better shoot growth (Slaton et al 2001).…”

This study evaluated how zinc (Zn) concentration of rice (Oryza sativa L.) seed may be increased and subsequent seedling growth improved by foliar Zn application. Eight foliar Zn treatments of 0.5% zinc sulfate (ZnSO 4 Á 7H 2 O) were applied to the rice plant at different growth stages. The resulting seeds were germinated to evaluate effects of seed Zn on seedling growth. Foliar Zn increased paddy Zn concentration only when applied after flowering, with larger increases when applications were repeated. The largest increases of up to ten-fold were in the husk, and smaller increases in brown rice Zn. In the first few days of germination, seedlings from seeds with 42 to 67 mg Zn kg À1 had longer roots and coleoptiles than those from seeds with 18 mg Zn kg À1 , but this effect disappeared later. The benefit of high seed Zn in seedling growth is also indicated by a positive correlation between Zn concentration in germinating seeds and the combined roots and shoot dry weight (r ¼ 0.55, p < 0.05). Zinc in rice grains can be effectively raised by foliar Zn application after flowering, with a potential benefit of this to rice eaters indicated by up to 55% increases of brown rice Zn, and agronomically in more rapid early growth and establishment.

“…Zinc is one of the most important micronutrient essential for plant growth especially for rice grown under submerged condition. Zinc deficiency continues to be one of the key factors in determining rice production in several parts of the country (Muthukumararaja & Sriramachandrasekharan, 2012).Zn deficiency is the most widespread micronutrient disorder in lowland rice and application of Zn along with NPK fertilizer increases the grain yield dramatically in most cases (Fageria et al, 2011;Singh et al, 2011).Apart from major nutrients zinc is very much responsive to high intensive cereal based cropping system. Zinc is required in a large number of enzymes and plays an essential role in DNA transcription.…”

Rice is the staple food of more than three billion people in the world, most of who live in Asia.Rice is important crop of Indo Gangetic Plains of Bihar, productivity of system is stagnate and somewhere going down, to ascertain the role of sulphur and zinc an experiment was conducted at main campus of ICAR Research Complex of Eastern Region Patna with four levels of both nutrients i.e. sulphur and zinc, total 16 treatments were tested in Randomized Block Design. Both the nutrients were applied to rice and their direct and residual response was ascertained to rice and lentil in sequence. Based on three years of experimentation, results revealed that rice plant height is significantly affected by sulphur and zinc. Tallest plant (101.7cm) was recorded at maturity with application 6kg Zn application Zn. With the advance of stage dry matter accumulation was increased, it was not like the LAI which was decreased after Panicle initiation stage. Highest LAI (4.29) at anthesis was produced in the plots treated with Zn at 6 kg/ha. Dry matter share of root was in general less than 15% across the levels of sulphur and zinc during all the phenological stages. Maximum rice yield (7.63 t/ha) was recorded with combined application of 30kg sulphur and 6kg zinc, whereas corresponding minimum rice yield (7.09 t/ha) was recorded with absolute control plots where no application of zinc and sulphur was done during entire experimentation period.Maximum (281.2 kg/ha) nitrogen uptake was recorded with 6kg zinc treatment. However highest uptake of P (91.1 kg/ha) and K (150.4 kg/ha) was recorded in the plot supplemented with no Zn and sulphur at 40 kg/ha, respectively. Soil parameters viz., pH, EC and organic carbon content did not influenced with the S and Zn. N, P, K, S and Znwere affected significantly due to sulphur and zinc nutrition.
