Effects of Trichoderma and Foliar Fertilizer on the Vegetative Growth of Black Pepper (Piper nigrum L.) Seedlings
Abstrak
Black pepper is a high nutrient-demanding crop; however, high application rates of the chemical fertilizer may give a negative
impact on the environment and human health. Coapplication of the chemical fertilizer with biological fertilizers or biological
agents is very important to support growth and high yield. (is field experiment was carried out to study the effect of Trichoderma
harzianum and foliar fertilization on the vegetative growth of black pepper. (e study was conducted for 4 months. (e research
method was arranged in a factorial based on randomized block design (RBD). (e first factor was the application of Trichoderma
(50 g, 75 g, and 100 g per plant), and the second one was foliar fertilizers (1.0%, 1.5%, 2.0%, and without foliar fertilizer as the
control). (e treatments were repeated three times. (e results showed that the application of both Trichoderma and foliar
fertilizer affected the rate of shoot growth, the number of leaves, and the emergence time on black pepper seedlings under the
nursery conditions. (e application of 50 g/plant of Trichoderma and 1.5% of the foliar fertilizer resulted in 26% longer shoot
length and 54% more leaves and accelerated the appearance of shoots 10 days earlier compared to without Trichoderma and the
foliar fertilizer.
