Pemanfaatan Kompos Gamal (Gliricidia sepium) dan Limbah Cair Tahu Terhadap Pertumbuhan dan Produksi Tanaman Jagung Manis (Zea mays L. Saccharata Sturt)

Abstract

The purpose of this research is about the growth and production of sweet corn (Zea mays L. saccarata Sturt). This research was conducted by using Factorial Randomized Block Design method consisting of 2 factors; Factor I = Application gamal compost consist of 4 treatment factors with each dose is =67,5 g of Urea fertilizer, 33,75 g of SP36 fertilizer, and 22,5 g of KCl fertilizer (control) = 1,125 kg per plot (5 ton/Ha) of gamal compost, = 2,25 kg per plot(10 ton/Ha) of gamal compost, = 3,375 kg per plot (15 ton/Ha) of gamal compost, Factor II= application of liquid organic fertilizer tofu waste consist of 4 treatment factors with each concentration is: = watering with water without liquid organic fertilizer tofu waste (Kontrol), = 125 cc/ liter water (12,5%) of liquid organic fertilizer tofu waste, =250 cc/ liter water (25%) of liquid organic fertilizer tofu waste, =375 cc/ liter water (37,5%). Parameters observed in this research were plant height (cm), leaf number (sheel), stem diameter (cm), production of wet cob plants (g) per sample, production of wet cob plants (g) per plot. The result of the research showed the application of gamal compost effect on cultivation of sweet corn plants that significantly effect the number of leaf at age 3 weeks after plant – 5 weeks after plant with the best treatment dose is (control), have significant effect on stem diameter at age 2 weeks after plant with the best dose that is (3,375 kg) and have significant effect on production of wet cob plants (g) per plot with the best dose that is (3,375 kg). Application of liquid organic fertilizer tofu waste and combained treatment of gamal compost and liquid organic fertilizer tofu waste manure had no signifificant effect on all parameter observed
