The performance of growth traits and yield of peanut with high oleic acid content under different sowing methods
The effects of different sowing methods(single-seed sowing,double-seed sowing,single and double grain interseeding)on growth traits and yield were studied by using the method of plot test comparison among the peanut(Arachis hypogaea L.)varieties(Zhonghua 215,Zhonghua 28,and Zhonghua 34)with high oleic acid content.The results demonstrated that different sowing methods had a certain effect on the growth traits and yield of the peanut with high oleic acid content.Single-seed sowing was more conducive to the growth and development of the peanut.Compared with the other two sowing methods,it could significantly increase the SPAD value of leaves,the number of pods per plant,the productivity per plant and the yield of dry pods.There was no significant difference in the yield of dried fruit between single and double grain interseeding and double-seed sowing.The economic benefit of single seed sowing was the highest,followed by single and double grain interseeding and double-seed sowing.Under the same sowing method,the yields and economic benefits of Zhonghua 215 were the highest,followed by Zhonghua 34,and Zhonghua 28 was the lowest.
