abstract
Flood is the major problem of Assam which mainly affect the rice during kharif season every year. It is observed that in recent years sometimes along with flash flood, drought like situation also arises and affected huge area of rice due to aberrant climatic condition. Therefore, an On Farm Trial was conducted by Krishi Vigyan Kendra, Lakhimpur during kharif, 2022 to evaluate the yield performance of two newly developed climate resilient rice varieties viz., CR Dhan 801 and CR Dhan 802 having both submergence and drought tolerance ability against the recently popular recommended submergence tolerant rice variety Ranjit sub 1 in three selected villages of Lakhimpur district of Assam. The results showed that both the tested varieties viz., CR Dhan 801 and CR Dhan 802 performed more or less similar but slightly higher than the submergence tolerant rice variety Ranjit sub 1 in respect of yield, yield attributes and economic point of view. Therefore, it can be said that along with rice variety Ranjit sub 1, the climate resilient rice varieties viz., CR Dhan 801 and CR Dhan 802 may also be cultivated in Lakhimpur district of Assam under both flood and drought like situation. But prolong dry spell during the cropping period may affect the yield of crop and in that case both the climate resilient rice varieties CR Dhan 801 and CR Dhan 802 may show the better yield performance than the existing popular rice variety Ranjit sub 1.
