  To investigate the effect of planting date on some quantitative and qualitative characteristics of rice cv. Binam, Tarom Mahali and Koohsar, a field experiment was conducted as factorial based on complete block design with three replications during three planting dates of 21 and 31 March, and 10 April in Deputy of the Rice Research Institute, Mazandaran Branch Amol, Iran. Three months after planting, 400 g of paddy sample for each plot was collected and evaluated to measure characteristics such as head and broken rice percentage, milling recovery, paddy hull and bran percentage, grain length before and after cooking, grain elongation ratio, milling degree, amylose percentage, gel concentration and gelatinization temperature. The effect of planting date and cultivar was significant on all characteristics in 1% probability level. The head rice percentage at first planting date and bran percentage, grain length after cooking, milling degree, gelatinization temperature, and grain elongation ratio at second planting date were better in Tarom Mahali cultivar. Grain length after cooking, grain elongation ratio and amylose percentage in Binam at the second planting date and bran percentage and grain length before cooking in Koohsar at the third planting date were better. The amount of broken rice percentage was lower at the first planting date in Binam and Koohsar cultivars compared with second and third planting dates. On the whole, transplanting at late April is recommended to get optimal quality of rice grains in this region Manuscript profile

  To determine the effects of planting date and nitrogen fertilizer on stem borer, blast disease and rice yield of in replanted rice cultivars of Koohsar, Binam, Tarom Hashemi, and Tarom Mahali, two separate experiments were carried out in split plot based on randomized complete block design during the growing years of 2015-2016 in Amol, Iran. The first experiment was the effect of nitrogen fertilizer with the amounts of 30, 60, and 90 kg/ha on rice cultivars. The second one was the effect of planting dates including 24 July, 3, 11, and 13 August on severity of stem borer, blast disease and rice cultivars yield. The severity of stem borer was about 18 on Koohsar, and 6 ~ 12% on Binam, Tarom Hashemi, and Tarom Mahali cultivars. The increase of nitrogen application rate resulted in significant increase of stem borer severity in vegetative and reproductive stages.The amounts of panicle node blast in Koohsar and Binam cultivars were 21 ~ 43 and 4%, respectively. Increasing nitrogen rate caused significantly higher rice yield, but application of 90 kg/ha N increased the severity of stem borer. There was no significant difference in stem borer severity among the studied cultivars. The stem borer and blast disease severity was in maximum level in the first planting date. Panicle node blast severity in Koohsar was more than local rice cultivars in all three planting dates. To obtain higher rice yield and less damage of stem borer and blast disease in rice replanting system, the second  planting date and 60 kg/ha of N fertilizer is recommended. Manuscript profile
