Abstract

The purpose of this study is to determine the effect of IBA plant growth regulators (Indole Butyric Acid)on germination of sugarcane cuttings (Saccharwn o_mcinarum L). The experimental materials include PSJT 941 variety of sugarcane cuttings, soil and manure as medium with 2: 1 ratio. IBA and 50% alcohol is used as treatment. Pest and disease controls used Basudin 60 EC and Dithane M-45. This study uses Randomized Block Design (RAK) with three replicates and each replicate consisted of 2 sample plants. The treatment is as follows: Ko: without treatment, K1: 500 ppm, K2: 1000 ppm, K3: 1500 ppm, K4: 2000 ppm. The study reveals that treatment of K4 IBA solution (2000 ppm)has very significant effect on variables of germination speed, shoot length, number of leaves and number of roots, and significantly different at root length. Administration of IBA solution at concentration of 1500 ppm accelerated germination time of sugar cane cuttings, occurred on the fourth day (fourth). Administration of IBA solution at 2000 ppm gave the highest result which was not different with 1500 ppm concentration on shoot length, leaf number, root length and root number. The higher the concentration of IBA, the higher the shoot length, the number of leaves, the length of the roots and the number of roots of sugar cane produced.

Abstract

The lettuce is a leafy vegetable that comes from the (state) temperate. Historically, this plant has been cultivated since 2500 years ago. Lettuce plants came from the Americas. This is evidenced by Christopher Columbus in 1493 that found the plant lettuce in the western Hemisphere and the Bahamas (Rukmana, 1994). This study aims to determine the effect of growing media on growth factors, the influence of the concentration of liquid organic fertilizer (POC), the interaction effect of these two factors and yield of lettuce. The results showed There is a very real effect of growing media composition in all parameters studied were long observation of plants, number of leaves and fresh weight per plant. The best results were achieved by treatment K2 is 2 kg of manure per plant. There is a very real effect of concentrated liquid fertilizer (POC) "Supermer" on all parameters studied were long observation of plants, number of leaves and fresh weight per plant. The best results are achieved by P4 treatment The concentration POC 2 ml / liter of water. There is no real interaction due to a combination treatment of the media composition and concentration of liquid organic fertilizer (POC) "Supermes".

Each treatment combination was repeated three times and each combination treatment consisted of 50 seeds watermelon. Factor I is the treatment of seed scarification consisting of without stripping, and stripping Factor II which is the soaking time of ZPT which consists of without soaking; 10 minutes immersion; 20 minutes soaking and 30 minutes soaking. Observations were made every day until the germinated seeds did not germinate again (7 days after germination), observations made included: Germination rate, germination percentage, radicle length, plumula length. The results of statistical analysis showed that the overall combination of seed scarification and soaking of ZPT against watermelon seed germination had not yet given a real interaction effect. Separately the seed scarification treatment had a significant effect on root growth of watermelon sprouts, and did not affect the growth of plumula length, germination percentage and sprout speed, but ZPT immersion treatment significantly affected the percentage of germination, sprout speed, root length growth, and length of plumula growth. . The average percentage of germination, germination rate, length of the plumula and the length of the watermelon seed radicles were best obtained in ZPT immersion treatment with 30 minutes soaking time, which was then followed by other treatments.
