Abstract

Tomato is an important vegetable crop and has been widely cultivated as a garden plant or commercially. The purpose of this study was to measure the effectiveness of organic fertilizer based on coal and cow dung based on several tomato varieties. This study used a factorial randomized design with two factors, namely the type of fertilizer consisting of "Saputra" coal fertilizer (BB), "Bio Alam Asri" manure (BA) and without organic fertilizer (B0); and the other factor is the tomato variety factor (V), namely Servo F1 (VS), Gustavi F1(VG), and Fortuna 23 (VF). Based on the results of the study, it was found that the treatment of BB and BA, in general, had a significant effect on vegetative growth and generative yields including fruit quality in the three tomato varieties tested. The highest number and fresh weight of tomatoes per plant were obtained in the treatment of BB, namely 44.00 fruits and 3.00 kg, higher than BA fertilizer, namely 39.11 fruit and 2.62 kg, and B0 namely 34.00 pieces and 2.20 kg. The highest number and fresh weight of tomatoes per plant were obtained in VS varieties, namely, 42.33 fruits and 2.74 kg, followed by VG varieties at 40.11 fruits and 2.71 kg and the lowest was VF at 34.67 fruit and 2.38 kg. The highest vitamin C content of fresh fruit was obtained in the BB treatment, which was an average of 36.75 mg/100g, higher than the treatment with BA fertilizer and B0, which were 32.81 mg/100g and 31.07mg/100g.

Abstract

The pumelo population in Bali is declining one is caused of a lack of good-quality seeds. This research was conducted to determine the effectiveness of organic coal fertilizer and rabbit farm waste as organic fertilizers for the growth of pomelo grafting seedlings. The research design used a nested pattern randomized block design with 3 replications. There are two factors, the first factor is the type of fertilizer, which are Coal fertilizers, Rabbit Farm Waste fertilizers, and Cow Manure fertilizers. The second factor is the dose of each type of fertilizer which consists of 3 levels, namely: 10 tons/ha; 20 tons/ha; and 30 tons/ha. The results showed that the effectiveness of the treatment of the type of organic fertilizer and the dose of the type of organic fertilizer had no significant effect on all observed variables. This shows that both coal fertilizer and rabbit manure have almost the same quality as cow manure in influencing the growth of pomelo seedlings. The effectiveness of fertilizers tested on the average shoot length of grafting tends to show the highest yields obtained at the highest dose (30 tons/ha), namely Coal fertilizer which is 28.80 cm, rabbit manure is 31.87 cm, and cow manure obtained is 28.13 cm.
