Effect of Chemical Fertilizers and Aerated Static Pile Compost on Growth of Green Shallot (Alliumcepa var. aggregatum)

Abstract

The purpose of this study was to examine the effects of chemical fertilizers and aerated static pile compost on growth of green shallots. The experiment was carried out using randomized complete block design (RCBD) consisting of four treatments and four replications. Treatment 1 chemical fertilizers were applied at the recommended rate from soil analyses, treatment 2 chemical fertilizers were applied at 75% of the recommended rate from soil analysis. Treatment 3chemical fertilizers at 75% of the recommended rate from soil analysis plus 200 kg/rai of dried aerated static pile compost were applied. Treatment 4, 200 kg/rai of dried aerated static pile compost was applied. Growth of green shallots was measured at 20 and 45 days after planting by counting the numbers of shallots per clump and weighing the fresh weight per plant and per clump. Statistical analysis of the means was carried out using DMRT method. It was found that there were no statistically significant differences inthe average numbers of plants per clump at both at 20 and 45 days after planting. The highest average number of plants per clump at 20 days after planting was in treatments 1and 2 (5.88 plants/clump) and at 45 days after planting was in treatment 2 (6.58 plants/clump). There were no statistically significant differences in the average fresh weight of shallots per plant and per clump. Treatment 3 had the highest fresh weight per plant of 2.33 gramsand highest fresh weight per clump of 18.60 grams.
