THE EFFECT OF TRICHODERMA ON N, P, K SOIL AND CORN PLANTS

Abstract

Excessive and uncontrolled use of chemical fertilizers and pesticides has resulted in various adverse effects on the soil. There needs to be a good way of managing healthy and environmentally friendly plants. This study examines the impact of using Trichoderma in combination with NPK fertilizer on nutrient conditions and nutrient uptake and growth of corn plants. This study used a Complete Randomized Block Design of 9 treatments control (A), standard NPK (Urea 350 kg ha-1, SP 36 200kg ha^-1 SP36, and KCL 75kg ha^-1 KCl) (B), ¼ NPK + 5 kg ha^-1 Trichoderma (C), ½ NPK + 5 kg ha^-1 Trichoderma (D), ¾ NPK + 5 kg ha^-1 Trichoderma (E), 1 NPK + 5 kg ha^-1 Trichoderma (F), ¾ NPK +1.25 kg ha^-1 Trichoderma (G), ¾ NPK +2.5 kg ha^-1 Trichoderma (H), ¾ NPK + 3.75 kg ha^-1 Trichoderma (I), with three replicates. The results showed that NPK fertilizer accompanied by Trichoderma was able to increase total N, available P, and available K in the soil, and the growth of maize plants from control the use of Trichoderma up to 5 kg/ha has not been able to reduce the use of NPK fertilizer
