Evaluating some qualitative and quantitative indices of local rice cultivars in paddy field planting systems in north of Iran
This experiment was conducted with the aim of evaluating the planting systems of local rice cultivars in the research paddy fields located in Neka, Sari and Babol during 2017 and 2018. Data analysis was done based on a factorial experiment in a complete randomized blocks design where planting system...

| description | This experiment was conducted with the aim of evaluating the planting systems of local rice cultivars in the research paddy fields located in Neka, Sari and Babol during 2017 and 2018. Data analysis was done based on a factorial experiment in a complete randomized blocks design where planting systems including conventional, high-input, transition to organic, organic, and low-input were chosen as the first factor and cultivars including ‘Sang Tarom’, ‘Tarom Mahalli’, and ‘Tarom Hashemi’ served as the second factor. Results demonstrated that the highest mean number of panicle per m2 in both years belonged to the high-input system. The highest fourth internode lodging index was obtained at interaction of high-input and conventional system with ‘Sang Tarom’. The maximum paddy yield in both years was produced in high-input and conventional systems. The highest grain phosphorous uptake, nitrogen harvest index, potassium harvest index, and gel consistency were achieved in high-input and conventional systems. The highest grain milling efficiency in the first year belonged to the conventional system (72.83%), but in the second year, it belonged to the transition to organic system (75%). Gelatinization temperature in both years was maximum in the conventional system while it was minimum in the low-input and organic systems. Regarding the findings, it can be stated that high-input and conventional systems resulted in increase of quantitative yield, but organic and transition to organic systems led to an increased NPK uptake and improvement of the grain baking related traits. |
