A chapter in Empirical Analyses on Rice Yield Determinants of Smart Farming in Japan, 2021, pp 49-60 from Springer

Abstract: Abstract This chapter identified the impact of rice variety and cultivation regimeCultivation regime on paddy yield in the large-scale farms. The study objects were 351 fields in a farm corporation of over 113 hectares, locating in the Kanto Region, and the yield was measured by smart combine harvesterSmart combine harvester The ANOVAANOVA (analysis of variance) result indicated that rice variety was a significant factor affecting yield; although the cultivation regimeCultivation regime was not significant, it had a significant interaction with the effect of rice variety. According to the result of Duncan’s new multiple range testDNMRT (Duncan’s new multiple range test) (DNMRT), the rice varieties were divided into three groups. Further analyses using four factors and the ANOVAANOVA (analysis of variance) results showed that the time of transplanting or sowing, growth duration from transplanting or sowing stage to earring stage, total nitrogen amount, and field area were determining factors. Finally, the key points for higher paddy yield were summarized.
