Growth and Yield Characteristics of Foxtail Millet, Proso Millet,Sorghum and Rice in Paddy-Upland Rotation

Abstract

In order to develop optimum paddy-upland rotation system, we evaluated the 1st and the 2nd upland growth and yield characteristics of foxtail millet, proso millet, sorghum rotated from paddy field and rice rotated from upland in paddy-upland rotation. Average number of ears per hill was 3.3 in the 2nd upland cultivation. The value was greater by 1 ear as compared to 1st upland cultivation (2.2 ears per hill). In average yield per 10a, the 2nd upland cultivation showed 220.3 kg, 23% increased yield compared to the 1st upland cultivation (179 kg per 10a). In average number of ears per hill, the 2nd upland cultivation showed 8.3 ears, increased 4 ears compared to the 1st upland cultivation (4.2 ears per hill). In average yield per 10a, the 2nd upland cultivation showed 152.8 kg, 16.8% increased yield compared to the 1st upland cultivation (130.8 kg per 10a). In average days from seeding to heading of 5 sorghum varieties, there were no significant difference between the 1st (68.6 days) and the 2nd (67.4 days) upland cultivation rotated from paddy field. In the average number of grains per ears, the 2nd upland cultivation showed 2,931.6 grains per ear, 12% increased compared to the 1st upland cultivation (2,619.6 grains per ears). Average yield per 10a of sorghum in the 2nd upland cultivation showed 242.3 kg, 4.6% increased compared to the 1st upland cultivation (231.7 kg per 10a). In growth and yield characteristics of rice in paddy-upland rotation, culm length in paddy-upland-paddy plot showed 82.9 cm, 7.3 cm longer compared to the continuous rice paddy field (75.6 cm). Ear length was also 1 cm longer than that of the continuous rice paddy field. In average number of ears per hill, paddyupland-paddy plot showed 25.0 ears, 4.3 ears more than that of the continuous rice paddy field (20.7 ears per hill). In average yield of rice per 10a, the paddy-upland-paddy rotation plot showed 526.8 kg, 9.8% higher yield compared to the continuous rice paddy field (479.9 kg per 10a).

Effect of Mixed Organic Fertilizer on Growth, Yield and Component Content of Saururus chinensis Baill in Paddy Field Cultivation

“…그러나 이상기후 등에 따라 쌀 부족 문제가 대두될 수 있고 국제 곡물가가 급 등할 수 있으므로, 식량사정에 따라 논과 밭으로 탄력적으로 이용할 수 있는 논의 관리체계가 필요하다 (Han et al, 2017). 논을 밭으로 이용하면 입단형성, 지력 증진, 통기성 증가, 병충해 억제, 수량증대 효과 (Lim et al, 2014;Youn et al, 2015)…”

“…기장은 개간지 및 척박지, 가뭄 등에 잘 적응하며 (Ha and Lee, 2001;Park et al, 1999; (Cho, 2010;Yoon et al, 2008;Yoon et al, 2015a;Yoon et al, 2015b;Yoon et al, 2015c Means with the same letter are not significantly different at the 5% level by DMRT. Capital letters indicate differences in the means of four cultivars, small letters indicate the difference of sowing times in each cultivar.…”
