Time and Space of Summer Soybean Yield in Henan Province
In order to explore the influence of year,place,variety and their interaction effect on soybean yield,1 1 soybean varieties approved by Henan Province were took as research objects,and the soybean yield of seven experimental sites in Henan Province from 2022 to 2023 was compared by multivariate variance and multivariate comparison.The results showed that the test accuracy of Zhumadian and Luohe had the strongest identification ability for the tested varieties.The effects of year,location,variety and their interaction on soybean yield reached a very significant level(P＜0.01).The contribution rate of location to soybean yield was 62.91％.Among the seven experimental sites,except Luoyang and Luohe,the average yield difference was significant among other experimental sites.The average yield of original sun was 3 776.43 kg/ha,which was 105.15％higher than that of Nanyang,which had the lowest average yield.The average yield of 11 tested varieties was significantly higher than that of Yudou 22(CK),and the average yield of Zheng 1311 was 3 049.7 kg/ha,with an increase of 14.35％;Mingdou 1 has the lowest yield increase of 4.24％.In actual production,selecting varieties with high yield,good quality and strong adaptability according to different conditions was more conducive to exerting the high yield potential of varieties.
