Effect of Compost Made from Chicken Manure Inoculated with Trichoderma SPP. on Growth, quality and Nutrient Uptake of Leafy Vegetables

The aim of this study was to investigate the effect of compost from chicken manure inoculated with Trichoderma spp. on the growth, quality and nitrogen uptake and phosphorusuptake of leafy vegetables. The experiment used a mix of 5 strains of Trichoderma spp. inoculated with chicken manure for 30, 60 and 90 days. The experiment was arranged in a completely randomized block design with 8 treatments, of which 3 treatments with vine spinach (Basella alba L.)had 30-,60- and 90-day compost (S-30, S-60, S-90); 3 treatments with amaranth (Amaranthtricolor L.) had 30-, 60- and 90-day compost (A-30, A-60 and A-90) and 2 controls without compost hadvine spinach (S-C) and amaranth (A-C). Results showed that with both vegetables, shoot fresh weight increased 30-40% and vitamin C content increased 20-30% compared to the respective control. There was no increase in shoot N concentration and N uptake of vine spinach in all treatments. However, amaranth shoot N concentration was 30% higher inA-60 than in A-C. Compared toA-C, N uptake in amaranth was two-fold higher in A-60 and 30-40% higher in A-30 and A-90. Shoot P uptake ofvine spinach was 20% higher in S-30 and S-60 than in S-C, while shoot P uptake of amaranth was 40-50% higher than A-C in all treatments with compost. It can be concluded that the compost ages of 30 and 60 days were better than 90 days in promoting the growth ofvine spinach, while the different compost ages equally affected the growth of amaranth.The 60-day compost also significantly increased shoot N concentration and shoot N uptake of amaranth.
