Comparison study of growth and yield of three soybean varieties on acid upland soil of South Lampung

Abstract

Lampung is mostly occupied by marginal acid upland soils. However, applying of suitable technology innovations could improve the soybean productivity in this marginal land. Until now, only a few field studies have been conducted on the adaptability of new soybean varieties in acid upland soils of Lampung. Therefore, present study’s objectives were to compare the agronomic performance and the yield of three soybean varieties on an acid upland soil of South Lampung. As the treatments, the three soybean varieties were Anjasmoro, Grobogan, and Dering 1. The research was set in a Completely Randomized Design with four replications. The results showed that in general, based on the agronomic performance, the Anjasmoro variety was more adaptable compared with Grobogan and Dering 1 variety. This might be related to the number of effective nodules in the rooting system of Anjasmoro variety which was higher than that of Grobogan and Dering 1 varieties. In addition, the Anjasmoro variety had the highest yield as 2.60 t ha−1 than that of the Grobogan and Dering 1 varieties as 2.33 and 1.99 t ha−1, respectively.

“…On the other hand, the seed weight of the Anjasmoro variety was from 9 to10 g per 100 seeds to 10 to12 g per 100 seeds, and the Dering 1 variety was from 9 to 11 g per 100 seeds to 11 to 12 in two locations. Similarly, in a study conducted by Diptaningsari & Rivaie [19], the Anjasmoro variety was more adaptable for planting on optimal land and less ideal for growing on suboptimal land than Dering variety. The seed weight of Dering 1 varieties ranged from 10 to12 g per 100 seeds that is still equivalent to the Dering 1 variety in general.…”

“…Seed production showed a positive correlation with the number of pods [11]. The output is a desired complex character which is inherited quantitatively [12][13][14][15].…”
