Effect of Trichoderma sp. and Streptomyces sp. on the growth and production of True Seed Shallots (TSS)

Abstract

Abstract A study aimed to determine the effect of Trichoderma sp. and Streptomyces sp. on the growth and production of True Seed Shallots (TSS) was conducted from April to October 2018 at the Teaching Farm, Faculty of Agriculture, Universitas Hasanuddin, Makassar, South Sulawesi. The experiment was set using a Randomized Group Design (RBD) replicated three times. The first factor was the application of Trichoderma sp. which consisted of three levels, namely control; 2 g per plant; 4 g per plant, while the second factor was the application of Streptomyces sp. consisted of three levels, namely: control; 10 4 cfu L -1 ; 10 8 cfu L -1 . The results show that the treatment of Trichoderma sp. at a dose of 4 g per plant resulted in better growth and production of shallots on the observed parameters ie. fresh weight of the bulbs per plot (686.60 g), dry weight of the bulbs per plot (532.48 g), production per plot (0.56 kg) and production per hectare (5.61 tons ha -1 ). No significant effect of Streptomyces sp. observed. Application of Trichoderma sp. and Streptomyces sp. on TSS tended to resulted in better growth and yield was the combination treatment of Trichoderma sp. 4 g per plant and Streptomyces sp. 10 4 cfu L -1 with an average production of 5.84 tons ha -1 .
