Abstract

ABSTRACT: The research aims to determine the effect of PGPR application on the incidence of fusarium wilt disease and tomato plant production. The research was carried out using a Randomized Group Design (RAK) with one treatment factor, namely the PGPR dose. Treatment was made in five levels, namely D0 (control/no PGPR), D1 (5 cc PGPR/liter air), D2 (10 cc PGPR/liter air), D3 (15 cc/liter air) and D4 (20 cc PGPR/liter air air). The results of in vitro PGPR testing provided an inhibitory response to Fusarium growth with an average of 47.32% on PDA media and 63.12% on NA media. The PGPR dose treatment tested did not have a significant effect on plant height, number of leaves, production characteristics and disease intensity, except for the average number of branches per tree, root length and root weight. Giving a dose of 20 cc/liter is the best dose to increase root character and number of branches.

Abstract

ABSTRACT: This study aims to determine the growth and yield of several genotypes of Unipa red corn. The research was conducted in the Sentani District, Jayapura Regency, from October 2021 to February 2022. The experiment was laid out in a Randomized Block Design (RBD) with a single treatment factor, consisting of 9 Unipa red corn genotypes, 1 local Jayapura genotype, and 1 national genotype. The observed variables included plant height, stem diameter, number of stem segments, length of stem segments, harvest age, cob length without husks, cob weight without husks, cob diameter without husks, weight of 100 seeds, seed weight per plot, seed weight per hectare, and seeds/cobs color. The results showed that: 1) The growth components of 11 corn genotypes vary greatly, and genotype treatment significantly affects the characteristics of plant height 7 MST, stem diameter 7 MST, and stem internode length; 2) The Unipa AMP-6 genotype had the highest productivity of 6.57 tons/ha; 3) The average harvest age of Unipa AMP corn was 87-88 days after planting; and 4) The genotype with the largest percentage of homogeneous seed color was AMP Unipa-8 (90.44%).
