Effects of wheat straw returning and potassium application rates on the physicochemical properties and lodging resistance of different stem internodes in direct-seeded rice

Abstract: A b s t r a c t. This study aimed to evaluate the relationship between the physicochemical properties and lodging index of different stem internodes and the yield of direct-seeded rice. Two treatments of wheat straw returning (returning and non-returning) and five potassium application rates of 0, 62.5, 125, 187.5, and 250 kg ha -1 were applied. Wheat straw returning combined with a potassium application rate of 125 kg ha -1 significantly promoted potassium accumulation, increased total soluble sugar and ligni… Show more

“…Rice (Oryza sativa L.), which belongs to the family Oryzeae, is an annual plant which is herbaceous, erect, superficially rooted, strong, and white (Xu et al, 2014;Rasooli Sharabiani and Khorramifar, 2022;Yinian et al, 2022). Rice is a staple food for about 2.5 billion people around the world and provides nearly 20% of the required energy and 15% of the protein requirements of these people (Qamar et al, 2013;Li et al, 2022). In general terms, tropical and subtropical countries such as Burma, Thailand, Vietnam, Laos, Indonesia, the Philippines, Pakistan, India, the United States, Japan, Italy, Egypt, China, Brazil, Cuba, Mexico, and Australia are the largest rice producers in the world.…”
