Abstract

This study aims to obtain doses of compost fertilizer and age of cutting point growing on the growth and yield of chrysanthemum plants. The experimental design used was a randomized block design with a factorial pattern consisting of 2 factors. The first factor is the dosage of compost fertilizer with 4 levels ie 0 ton ha-1, 5 ton ha-1, 10 ton ha-1, 15 ton ha-1. The second factor is the age of cutting point of growth with 3 levels ie 1 week after planting, 2 weeks after planting, 3 weeks after planting. This experiment was conducted in Pancasari Village Sukasada District Buleleng Regency with altitude of 1,247 m above sea level, this research took place from May 9 until August 10, 2017. The highest weight of secondary branching stalk, obtained at interaction dose of 15 tons ha-1 compost with age cutting growth point 1 week after planting that is 98,27 gram increase equal to 55,65% compared dose of compost 0 ton ha-1 with age cutting point growing 1 week after planting that is 43,58 g.

Abstract

This study aims to determine the growth response and yield of chrysanthemum plants in the application of several types of mulch and organic fertilizer. This research uses the basic design of Randomized Block Design with the factorial pattern with 2 factors and 3 replications. The first factor is mulch treatment consisting of 3 levels ie without mulch, rice husk mulch, and black silver plastic mulch. The second factor is organic fertilizer consists of 3 levels namely petrogenic, cow manure and chicken manure. The research results showed that the highest weight of flower stalk was obtained in silver black mulch treatment, increase of 9.63% when compared with the weight of the lowest flower stalk. The highest economic fresh weight was obtained in mulch treatment, increase of 17.53% when compared with the lowest fresh economic weight on mulch rice husk mulch treatment weighing. The highest weight of the flower stalk was obtained in the treatment of cow manure, increased of 10.14% when compared with the lowest weight of the flower stalk obtained in the treatment of cow manure weighing. The highest economic fresh weight was obtained in the cow manure treatment, which increased by 9.91% when compared with the lowest fresh economic interest weight obtained in the treatment of petrogenic fertilizer weighing.

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.

Abstract

Cabbage plants (Brassica oleracea) belong to the Brassicaceae family, is a vegetable that is widely cultivated by farmers in rural Indonesia. In an effort to increase the productivity of purple cabbage it is necessary to carry out soil management. Andisol is one type of soil that is relatively fertile but has a high level of P absorption so it is necessary to add Chicken Manure and TSP Fertilizer. The purpose of this study is to determine the effect of treatment and response from the combination of treatment on the application of chicken manure and TSP fertilizer on the growth and production of purple cabbage plants. The research design used was a group randomized design (RAK) with 2 factors arranged factorially. The first factor is chicken manure fertilizer which consists of 3 levels, namely: K1 = chicken manure fertilizer 10 tons / ha (50 grams / polybag), K2 = chicken manure fertilizer 20 tons / ha ( 100 grams / polybag) and, K3 = chicken manure fertilizer 30 tons / ha ( 150 grams / polybag). The second factor of TSP fertilizer consists of 3 levels, namely: T1 = TSP 200 kg / ha ( 1 gram / polybag), T2 = TSP 300 kg / ha ( 1.5 grams / polybag) and, T3 = TSP 400 kg / ha ( 2 grams / polybag). Treatment of Chicken Manure (K), TSP fertilizer, and Interaction (KxT) had no real effect (P ≥0.05) on the variables of maximum plant height, maxmium leaf count, root length, flower crop diameter and wet weight of crop per plant.
