Abstract

This research aimed to study the effect of interaction between organic fertilizer and MOL dose of banana weevil on soybean growth. The research was carried out at the UNSRAT Experimental Garden, at Wailan, Tomohon, from May to September 2020. The research in the form of a pot experiment was designed using a factorial randomized block design. The treatment consisted of, Factor I (A) = Type of Organic fertilizer. A0 = No organic fertilizer, A1 = 20 tons/ha of manure, A2 = 20 tons/ha of kitchen waste fertilizer. Factor II (B) = MOL dose of banana weevil. B0 = No MOL; B1 = 0.5 liter MOL ; B2 = 1 liter MOL, B3 = 1.5 liter MOL. Each treatment was repeated three times to obtain 36 experimental pots. The variables observed were the height and weight of soybean plants. The data were analyzed using analysis of variance and if there was a treatment effect, it was continued with the Least Significant Difference Test (BNT 5%). The results showed that the interaction effect between organic fertilizer and MOL dose was not significant on plant height and plant weight of soybeans. The treatment of organic fertilizer and the dose of MOL alone had an effect on plant height and weight of soybean plants. The highest soybean crop was without organic fertilizer application but for the MOL treatment it gave the highest plant. The highest soybean plant weight was at 20 tons of manure/ha.

Abstract

The purpose of this research was to determine differences in sulforaphane content in sprouts, cauliflower seedlings, mature plants from white flower cabbage, broccoli, cabbage and Chinese cabbage. This research was conducted in Tomohon and analyzed in the Chemistry laboratory of the State Polytechnic of Malang. The research method used was a randomized block design with 4 treatments, namely broccoli, white cauliflower, rock cabbage and Chinese cabbage with 3 repetitions in each growth phase. The results of the analysis of sulforaphane content in the growth phase of sprouts were the highest in broccoli, which was 117.08 ug, higher than white cauliflower (0.72 ug), rock cabbage (16.58 ug) and Chinese cabbage 0.38 ug). Furthermore, in the young plant phase the highest sulforaphane content in broccoli was 0.679 ug compared to white cauliflower (0.018 ug), rock cabbage (0.183 ug), and Chinese cabbage (0.003 ug). Then lastly, the highest sulforaphane content in mature plants was rock cabbage, which was 0.776 ug compared to broccoli (0.148 ug), white cauliflower (0.273 ug), and Chinese cabbage (0.001 ug). So the sulforaphane content in the sprouting phase of broccoli was higher than that of white cauliflower, rock cabbage and cabbage sprouts. Similarly, in young plants and in mature plants, rock cabbage showed higher sulforaphan content.

Abstract

This research was conducted to study the effect of the interaction between three types of manure and Phonska fertilizer on the growth of chili plants, as well as to obtain the type of manure and the dose of Phonska fertilizer in increasing chili growth. The treatments were arranged in a factorial randomized block design (3x4) with three replications. The first factor (A) is three types of manure, namely A1 = 10 tons / ha of cow manure, A2 = 10 tons / ha of goat manure, A3 = 10 tons / ha of chicken manure. The second factor (B) is the dose of Phonska fertilizer; namely: Bo = without Phonska; B1 = 100 kg Phonska /ha, B2 = 200 kg Phonska /ha, B3 = 300 kg Phonska /ha. All experiments were repeated three times to obtain 36 experimental units. The variables observed in the study were plant height and number of chilies. The results showed that goat and chicken manure gave the highest plant height, as well as the number of chilies. The best chili plant growth was at a dose of 10 tons/ha of goat manure and 10 tons/ha of chicken. At 100 kg/ha Phonska fertilizer gave the best chili growth. The lowest plant height and the least number of fruits were found in the treatment without Phonska fertilizer.

Abstract

Mustard (Brassica juncea L.) is a horticultural plant that acts as a source of vitamins and minerals. For this reason, mustard cultivation needs to be developed. The development of mustard cultivation can be done through the selection of the right planting media to support the growth of vegetable crops, especially on limited land. This study aims to study the effect of differences in the composition of the growing media on the growth and yield of mustard greens. The study was arranged in a completely randomized design consisting of four treatments. The treatment consisted of media: A = soil; B = soil + manure (1:1); C = soil + manure + compost (1 : 1 : 1); D = soil + manure + sand (1 : 1: 1). Each treatment was repeated four times to obtain 16 experimental pots. Variables observed: Plant height (measured 2 and 4 weeks after transplanting seedlings), Number of leaves (measured 2 and 4 weeks after transplanting seedlings), Wet weight of mustard greens (weighed at harvest). The data were analyzed using analysis of variance and if there was an effect of treatment, it was continued by using the BNT test at the 5% test level. The results showed that the planting medium given manure gave the best growth and yield of mustard greens. The composition of the planting media, soil + manure + compost (1 : 1: 1) is good for the cultivation of mustard plants.

Abstract

Indonesia is the second largest vanilla producer in the world. Vanillin produced from the drying process of vanilla fruit is the second most valuable commodity in the food and beverage industry in the world. The main obstacle for vanilla cultivation in Indonesia is the attack of vanilla stem rot (BBV). The cause of disease (pathogen) BBV in Indonesia is Fusarium oxysporum f.sp. vanillae. Therefore, it is very important to obtain information about the population of the pathogen Fusarium oxysporum f.sp. vanillae to support the successful assembly of vanilla varieties that are resistant to Fusarium oxysporum f.sp. vanillae. Currently, information on the diversity of the pathogenic population of Fusarium oxysporum f.sp. vanillae in North Sulawesi Province is unknown. This study reports the diversity of the pathogenic population of Fusarium oxysporum f.sp. vanillae originating from North Sulawesi. Samples of stem rot were taken from several villages in Minahasa and Southeast Minahasa and South Minahasa districts. The stem rot samples were taken to the laboratory for isolation and identification. The variation observed was based on the appearance of the isolates on PDA (potato dextrose agar) media. The results showed that the appearance of the isolate Fusarium oxysporum f.sp. vanillae varies based on PDA media.

Abstract

Watersheds have some important roles for life in the vicinity, such as storing rainwater and flowing it as a water source. Disturbances in watersheds can causes soil erosion, which also causes the loss of fertile soil layers and carries solids and chemicals that can harm agricultural and human activities. Erosion prediction can be done by using the RUSLE method. The purpose of this study is to determine the rate of erosion in the rehabilitation area of the Bantik’s watershed. The result of this study is to indicate that the erosion in the rehabilitation area of the Bantik’s watershed is dominate by very light erosion with the lowest value around 1.04 tons/ha/yr and the highest value around 81.02 tons/ha/yr. It is necessary to take conservation measures on the soil and slopes so that erosion does not exceed its natural limits.
