Respon Pertumbuhan Sambung Grafting Durian (Durio Zibethinus Murr.) Terhadap Pemberian IAA (Indole Acetic Acid) dan Pupuk Organik Super Bionik

Abstract

This research was done to examine response of growth durian grafting on IAA dosage and Super Bionik organic fertilizer. Factorial Randomized Block Design was used with 2 factors. The first factor was IAA (I) which consisted of 4 level, those are I0 (0 mg/1 of water), Ii (30 mg/1 of water), I2 (60 mg/1 of water), I3 (90 mg/1 of water). The second factor was Super Bionik organic fertilizer (S) which 4 level, those are S0 (0 cc/1 of water), Si (2,5 cc/1 of water), S2 (5,0 cc/1 of water), S3 (7,5 cc/1 of water). There are 16 treatment combinations with 3 replications. As the result of the research base on statistical data analysis, IAA was significant with length of bud 16 week after grafting (WAG), bud diameter 16 WAG, leaf width total, and bud dry weight, but not significant with leaf amount. Super Bionik organic fertilizer was significant with length of bud 16 week after grafting (WAG), bud diameter 16 WAG, leaf width total, and bud dry weight, but not significant with leaf amount. The interaction between IAA and Super Bionik organic fertilizer was significant with length of bud and leaf width total. It was concluded that durian grafting used concentration of IAA between 40 mg/1 of water - 52 mg/1 of water, and Super Bionik organic fertilizer between 3 cc/1 of water - 4 cc/1 of water.
