The comparative effect of Macro and Microelements on the qualitative and quantitative characteristics of the rice plant (Oryza sativa L.)

Abstract

To examine the effect of macro and microelements on the quantity and quality of the rice plant, the present study has been done. The experiment was carried out at split- split plot design in randomized complete block with 3 replications. Macro element, S powder and microelements fertilizers have been chosen as main, sub and sub-sub plots, respectively in this research. The number of tillers, plant height, panicle length and the number of seed per panicle has been measured as quantitative properties of the rice plant. Protein and Amylose content were measured in the rice grain as qualitative characteristics. The results showed that NPK, S and Zn, Cu and Mn–fertilizers applied increased significantly all of quantitative properties of the rice plant except 1000 paddy weigh. It was also observed that amylose content decreased in the plot when Mn-fertilizer applied but, it increased when NPK, S and Zn, Cu and Mn–fertilizers applied together. Protein content increased also using NPK fertilizer and it was attained the maximum content when NPK, S and Zn, Cu and Mn- fertilizer were applied together. This treatment can be defined as critical level for amylose and protein content in the grain.
