en Effect of different fertilizers on nutrient uptake, some morphological traits and protein and amylose content of rice grain Effect of different fertilizers on nutrient uptake, some morphological traits and protein and amylose content of rice grain سایر موارد others پژوهشي Research <div style="text-align: left;">To examine the effect of S powder macro- and microelements on the nutrient uptake and morphological traits of rice grain protein and amylose content, the present study was carried out in 2014 in a paddy field in Babool city, located in Northern Iran, and all samples were tested at both the Mazandaran Agricultural Research Institute and the chemical laboratory of Pune, India. The results showed that macro elements affected the N, Ca and Na content very significantly. N and P grain content were significantly affected when macro and S powder were applied. K grain content was not influenced by any treatments. Ca and Mg grain content decreased very significantly when S powder and microelements were applied separately or together. Macro- and microelements decreased Na grain content very significantly. Amylose content was also affected by microelements very significantly. The minimum Ca (0.33%), Mg (0.14%), and Na (0.035%) and the maximum N (1.43%), P (0.19%), protein (8.54%), amylose (19.7%) content, germination ability (91.6%), and seedling (8.39 cm) and rootlet (5.30 cm) length were attained when NPK+S+Zn, Cu, and Mn-sulfate fertilizers were applied together. This treatment can be recommended to attain maximum amylose and protein and minimum Ca, Mg, and Na content that is also the best treatment for suitable viability of rice grain.</div> To examine the effect of S powder macro- and microelements on the nutrient uptake and morphological traits of rice grain protein and amylose content, the present study was carried out in 2014 in a paddy field in Babool city, located in Northern Iran, and all samples were tested at both the Mazandaran Agricultural Research Institute and the chemical laboratory of Pune, India.
