Abstract:

A one-factor field experiment of randomized block design was carried out to investigate the yield, economic benefit of chewing cane and peanut, as well as the soil physicochemical properties before planting (BP) and after harvest (AH) under different chewing cane-peanut intercropping treatments. Three intercropping treatments including chewing cane-peanut (1:2) intercropping (T2), chewing cane-peanut (1:1) intercropping (T1) and chewing cane mono-cropping (T0) were designed. Compared with T0, chewing cane-peanut intercropping patterns (T2 and T1) had no significant effect on the agronomic traits yield of chewing cane and peanut. Analysis results on the soil physicochemical index before planting (BP) and after harvest (AH) indicated that the chewing cane-peanut intercropping patterns could significantly increase soil organic matter and soil available nitrogen contents, but decrease soil available potassium contents, and the effect of T2 was more obvious than that of T1. The economic benefit of chewing cane-peanut intercropping patterns could significantly increase the total output and economic benefit. The benefits of chewing cane-peanut (1:2) intercropping (T2) was significantly higher than that of chewing cane-peanut (1:1) intercropping (T1). The land equivalent ratio (LER) of chewing cane-peanut intercropping patterns of T2 and T1 was 1.94 and 1.72, respectively. It is suggested that LER of chewing cane-peanut intercropping patterns was significantly higher than that of T0. The correlation analysis of output, cost and profit among the three chewing cane-peanut intercropping patterns showed that chewing cane-peanut intercropping partly increased planting cost, but significantly enhanced the gross output and profit. In conclusion, chewing cane-peanut (1:2) intercropping (T2) had minimal impact on the yield of chewing cane and peanut, and soil physicochemical properties, and also the best economic benefit among the treatments.
