Tingkat Keberhasilan Pertumbuhan Stek Lada dengan Aplikasi Naungan dan Berbagai Hormon Tumbuh Auksin

Abstract

One of the successes of black pepper production is influenced by the use of healthy and good quality black pepper seedlings. Black pepper nurseries are directed to produce quality black pepper seedlings with a faster seeding time. The research aims to determine the growth of pepper cuttings due to shade and auxin treatment. The study was conducted in Jerora I village, Sintang district, in August-December 2018. The study used a split-plot model research design. The main plot was shade (shade 25% (n1) and shade 75% (n2)) and subplots in the form of auxin hormone treatment (ho as control, (h1) 1% synthetic IAA, (h2) onion extract, and (h3) sprout extract using pepper cuttings using pepper cuttings. 3 sections and shading treatment using paranet. The administration of auxin treatment is done by immersing the tip of cuttings for 3 hours, pepper cuttings are placed in a lid to keep moisture in. The results showed that the percentage of cutting growth at 75% shade was higher than the shade of 25% IAA hormone use. can increase plant height at the beginning of growth, number of leaves and root dry weight. The origin of IAA used from natural ingredients is better than the synthetic type as evidenced by the results of the application of the sprouts extract, namely producing a root dry weight of 0.42 g, and a root shoot ratio of 0.61%. Increased growth due to IAA growth is better if placed in a darker shade that is 75% paranet shade.
