This research was conducted at Teaching and Research Farm, Faculty of Agriculture, University of Jambi. The aimed of this research were to determine the effect of different types of liquid organic fertilizers on the growth and yield of two varieties of lettuce. Experimental design used was a Randomized Block Design with eight treatments and three replications. The treatments were Variety Lettuce + without organic liquid fertilizers, Lettuce + Golden Harvest, Lettuce + Grow Quick, Lettuce + Alam Natural, Variety Grand Rapid + without organic liquid fertilizers, Grand Rapid + Golden Harvest, Grand Rapid + Grow Quick, Grand Rapid + Alam Natural.. The result showed that, there were no significant effect of organic liquid fertilizers on the increase in plant height, the increase in number of leaves, but significant effect of the increase in leaf area. Plant fresh weight (yield) of variety Lettuce with liquid organic fertilizer Golden Harvest gave the highest yields.Keywords: Organic, leaf, fertilizers, height.

Abstract

Low soil fertility is one of the main factors responsible for low productivity of tomato in Jambi Province. Soil fertility can be presumably enhanced by organic and inorganic fertilizers application. The objective of this experiment was to investigate the effect of different organic and inorganic fertilizers combination  on  plant growth and yield. One of the liquid organic fertilizer  that commonly  used     is Hantu organic fertilizer.  The research design was Randomized Block design, the treatment is organic fertilizer Hantu combined with various doses of inorganic fertilizers, 2000 ppm of organic fertilizer +  0.0 % of inorganic fertilizers, 2000 ppm of organic fertilizer + 25.0 % of inorganic fertilizers, 2000 ppm of organic fertilizer + 50.0 % of inorganic fertilizers, 2000 ppm of organic fertilizer + 75.0 % of inorganic fertilizers, 2000 ppm of organic fertilizer + 100% of inorganic fertilizers and 0.0 ppm of organic fertilizers +100% of inorganic fertilizers. Variables measured were plant height, plant dry weight, number of flowers per plant, number of fruits per plant, percentage of flowers become fruit, and fruit weight per plant. The results showed that application of 2000 ppm of organic fertilizer and 75.0 % of inorganic fertilizers showed the best growth and yield of tomato plants.      Keywords: Hantu organic fertilizer, inorganic fertilizer, tomato
