Abstract

Long-term cultivation of rice in paddy fields along with such chemical fertilizers as nitrogen and phosphorus, without using the other nutrients required for plants, and the natural limitations of soil have resulted in available phosphorus accumulation and available zinc reduction in soil. High YIELD Neda and Local Tarom varieties are the main strategic rice varieties, which are grown in Mazandaran province. Several reports have indicated that rice is a sensitive crop to zinc deficiency. Disorder is common in flooded fields and in such soils as sodic, calcareous, organic ones, and in soil with poor drainage conditions. In order to investigate the effects of ZINC SULPHATE (ZnS04, 7H2O) fertilization on the YIELD of two varieties (i.e. Tarom and Neda) an experiment was conducted in completely randomized block design in 11 sites of East of Mazandaran. The experiment was done on Neda variety in 8 sites and on Tarom in 3 sites. Treatments included 0, 50, 100 and 150 kg of zinc sulhate with 3 replications. Land preparation was done on the basis of the traditional methods in fanning. The dimensions of plots were 3x4 meters with 165 rice plants in each plot. Eighty plants were harvested from each plot, the YIELD was calculated on the basis of standard moisture of 14%. Results have shown that there existed significant differences among the average YIELD in Neda var. treatments at 5% level. Furthermore, the YIELD increased to 11.6% in comparison with the control. The reason for the lack of significant difference of YIELD in Bushel site was the high level of soil zinc. On the contrary, the low level of soil zinc Aristech site resulted in significant differences in three treatments in comparison with the control. Considering several experiments of different varieties in several countries and considering the results of this research, Neda, which has high YIELD, is a sensitive variety to zinc deficiency. It is inevitable to pay attention to the real nutrition requirement of this variety. The fertilization of ZINC SULPHATE on Tarom variety has not had a positive and economic response.
