Analysis of Population Yield and Benefit of Different Sweet Potato Varieties Intercropped by Maize
Year: 2014
Type: article
Abstract: Seven different varieties of sweet potato were used to study their population yield advantage and economic benefit when they intercropped with maize through using randomized block design. The results showed that the yield of sweet potato under this intercropping mode was lower than that under monocropping mode. Under sweet potato- maize intercropping mode,there was a significant difference in the number of tubers per plant,tuber weight per plant,and tuber yield among different varieties of sweet potato. The tuber yield and starch yield of sweet potato were higher when maize intercropped with Nanshu 88,Xushu 22 and Yushu 2.When 7 sweet potato varieties intercropped with maize,the land equivalent ratios of complex populations were all more than 1,revealing that the intercropping advantage existed. The monocropping or intercropping of special sweet potato varieties( Ning 4- 6,Jiheishu 1,E08101 and so on) with maize obtained a higher output value.
