APLIKASI PUPUK HAYATI DAN KANDANG UNTUK PENGENDALIAN LALAT BIBIT PADA TANAMAN KEDELAI
The objectives of this research were to find out dosages of biofertilizer and manure which was the most effective to control bean fly (A. phaseoli). This research was carried out at Cot Cut Village, District of Kuta Baro, Aceh Besar, from September to December 2008. This research used a factorial randomized complete block design with two factors: biofertilizer (H) and manure (K). Dosages of biofertilizer were H1= 2,8 L ha-1, H2= 3,5 L ha-1, H3= 4,2 L ha-1, and H4= 4,9 L ha-1. Dosages of manure fertilizer were K1= 2,8 ton ha-1, K2= 5,6 ton ha-1 and K3= 8,4 ton ha-1. The result showed that application of biofertilizer was more effective than that of manure fertilizer to percentage rates of the attacked plant. However, both biofertilizer and mature fertilizer exerted significant effects to percentage of plant death, plant dwarf, number of larva and pupa, and dry seed weight per plant. Application of biofertilizer at 4,9 L ha-1 and manure fertilizer at 8,4 ton ha-1 reduced percentages of plant death up to 86% and 83%, respectively
PENGARUH PUPUK HAYATI TIENS GOLDEN HARVEST TERHADAP PERTUMBUHAN BIBIT KAKAO
This study was aimed at determining effect of various concentrations of biological fertilizer Tiens Golden Harvest (TGH) on growth of cocoa seedlings.TGH fertilizer concentrations studied consisted of 4 levels, i.e. 0 mlL-1 water, 5 mlL-1 water, 10 mlL-1 water, and 15 mlL-1 water.The results showed that concentrations of TGH fertilizer significantly affected height of cocoa seedling at 30 and 60 day after planting (DAP), and stem diameter of cocoa seedling at 20, 30, 40, 50 and 60 DAP. The best TGH fertilizer concentration was found at 15 mlL-1 water.However, TGH fertilizer concentration did not significantly affect height of cocoa seedling at age of 10, 20, 40 and 50 DAP, stem diameter at age of 10 DAP, leaf area, root length, wet and dry weight at 60 DAP
APLIKASI BEBERAPA DOSIS HERBISIDA PARAQUAT PADA BIDURI DENGAN UMUR YANG BERBEDA
The study on application of different dosages of paraquat herbicide on different ages of milkyweed (Calotropis gigantea R. Br) have been conducted in Experimental Station, Agriculture Faculty, Syiah Kuala University, Darussalam Banda Aceh. The treatments were arranged in a Completely Randomized Design (CDR) with two factors. The first factor was dosages of herbicide which were 0; 0,1; 0,2; 0,3; and 0,4 kg active ingredient (a.i.) ha-1. The second factor was ages of C. gigantea R. Br which were 30 days, 45 days and 60 days after planting. The result showed that dosage of 0,3 kg i.a. ha-1 significantly increased the percentage of C. gigantea R. Br and decreased the dry weight shoot and root of C. gigantea R. Br. The youngest stage of C. gigantea R. Br was more effective to be controlled, and had a lower dry weight shoot and root than the oldest one. The paraquat herbicides applied with dosages of 0,3 kg a.i. ha-1 on 30 days after planting increased the percentage of C. gigantea R. Br, and reduced shoot and root dry weight of C. gigantea R. Br

KANDUNGAN UNSUR HARA TANAH DAN TANAMAN SELADA PADA TANAH BEKAS TSUNAMI AKIBAT PEMBERIAN PUPUK ORGANIK DAN ANORGANIK
Various forms of soil damage can be seen from the changes in physical properties, chemical and biological soil which happens in almost all coastal areas affected by the tsunami. The objectives of the study were to investigate the influence of organic and inorganic fertilizers in tsunami-affected lands on the growth of lettuce, and elemental content of N, P, and K in soil and plants. Experiment was carried out in polybags. Result showed that organic and inorganic fertilizer increased nutrient status of N and P soil, increased growth and nutrient content of N and P in lettuce plants. While for nutrient content of K, organic and inorganic fertilizer only affected soil and roots of lettuce. Growth and nutrient content of N, P and K in soil and plants due to organic and inorganic fertilizer application was highly dependent on the dosage given. The best growth of lettuce was obtained at combination of organic fertilizer 30 tons/ha with inorganic NPK fertilizer 1000 kg/h
