The Research has been conducted in Pandu Experimental Garden, Talawaan Bantik Village, North Sulawesi, titled “Intercropping of Several Cultivars of Banana and Plantain under Coconut Based in North Sulawesi, Indonesia”. The aims of the research were to study suitability of several banana and plantain intercropped into coconut based farming system. The materials and methods used were monoculture coconut plantation, hybrid Khina-1 planted in 1986, designed in RCBD, 5 treatments were the banana and plantain cultivars Mas, Gapi, Gepok Tanjung, Goroho and Raja. Then the Least Significant Difference Test (LSD) was used for mean separations. Significantly, was determined at the p=0.05 probability level. In this experiment also, using t-test to compare the effect of natural shade of the coconut canopy with an open field for the five varieties tested. Then, using 20 plants for each variety and treatment, served as replication. Two dwarf cultivars, Mas (banana) and Goroho (plantain) indicated the significant vegetative and generative growth shorter than the three tall cultivars, Gapi, Gepok Tanjung and Raja. It is also concluded that coconut based using Hybrid Khina-1 varieties, spacing 8m x 8m square system is suitable for intercropping with banana and plantain, especially the Dwarf Mas and Goroho.
An experiment to observe the influence of compost by ricestraw in potato production has been conducted in North Sulawesi from April to October 2015. Therefore this research was conducted with the objectives: (1) to find out the effects of rice straw-based compost compared to manure on potato production; and (2) to ensure the use of compost without inorganic fertilizer in the potato-based farming system as a basis of organic farming system in the production center of potato in Western Indonesia. The treatments were designed into CRBD proceeded to the Least Significant Difference Test (LSD test). Six treatments were applied, A=Compost 20 t.ha-1 plus inorganic fertilizer; B= Manure 20 t.ha-1 plus inorganic fertilizer; C= Compost 20 t.ha-1 without inorganic fertilizer; D= Compost 12 t.ha-1 plus inorganic fertilizer E= Compost 12 t.ha-1 without inorganic fertilizer and F= Manure 5 t.ha-1 plus inorganic fertilizer. Parameters tested show that the treatments of compost have advantages compared with the manure treatment. This related to the nutrients composition of straw rich especially potassium. Treatment A (Compost 20 t.ha-1 + inorganic fertilizers) is not significantly different from treatment C compost 20 t.ha-1 without inorganic fertilizers) in almost parameters except tuber weight of Grade #1 (industry purposes), describing the potency of the organic agricultural system of potato by using compost rice straw based. However, the organic agricultural system economically could be applied by the farmer as well as ease to get the materials. It also provides sustainable agricultural practices in the production center of a potato.
The abundance of agricultural products often causes environmental problems. The utilization of agricultural waste from carrots can reduce both the feed cost and environmental pollution and become a source of vitamin A for the health of the native chicken. The study aims to analyze carrot (Daucus carota L.) waste juice on native chicken performance. It was conducted from April to July 2019 at Pandu experimental field in North Minahasa Regency. The practical method used was a completely randomized design with four replications. The experimental livestock used in the study was 80-day-old chickens of native chicken. The concentration of carrot juice during the study was as follows: 100% drinking water without carrot juice (W0), 80% water drinking + 20% carrot juice (W1), 60% drinking water + 40% carrot juice (W2), and 20% drinking water + 80% carrot juice (W3). Observed variables included feed intake, body weight gain, feed conversion ratio (FCR), and mortality rate. The results showed that carrot waste juice significantly impacted the body weight gain, feed conversion rate, and 0% mortality rate during the 8 weeks. The concentration of 20% drinking water + 80% carrot juice (W3) with the feed intake ratio of 1.608 g, body weight gain value of 775.63 ± 301 g, and the FCR of 2.1 ± 0.06. However, the consumption ratio did not differ among treatments. The addition of carrot waste juice, as much as 80%, in the drinking water of native chickens showed an increase in body weight compared to other treatments. In conclusion, the current study showed that treatment of carrot waste juice has a significant effect on body weight in 8 weeks of maintenance. Meanwhile, the feed intake ratio of carrot waste juice treatment has no real effect. There was no dead chicken (0%) in the present study. The carrot waste juice can be used in chicken drinks 40–80% by paying attention to the balance of energy content and feed proteins used to grow chickens.
North Sulawesi is Famous as spicy culinary in Indonesia, therefore hot chili become the most important vegetable commodity in this region. An experiment to observe the influence of compost and manure on hot chili production has been conducted at Pandu Experimental Station in January to September 2018. The treatments were designed into RCBD proceeded to the Least Significant Difference Test (LSD test). Six treatments were applied, Control, without fertilizer; Inorganic fertilizer; Compost; Manure; Compost +inorganic fertilizer and Manure + inorganic fertilizer. The main parameter tested is the fresh fruit weight shown that the best treatment obtained is the treatment compost+ inorganic fertilizer, the total fresh weight gotten within 8 months productive age is 742 gr per plant, followed by the Manure + inorganic 696 gr per plant, these significantly higher than other treatments. The compost treatments are relatively better than the commercial manure due to its well decomposition of compost compared to the commercial manure. Financially, the farming also is feasible where R/C Ratio were above 1.2. The R/C Ratio were 2.83; 2.42 and 1.41 respectively for treatment E, B and A.
A Research has been conducted in Pandu Experimental Garden, Talawaan Bantik Village, North Sulawesi, in 2017-2019. It is located in suburb area of Manado City having high demand of fruits, mainly papaya The objectiveness of the research was to analyze the technical and financial feasibilities of papaya merah delima cultivated in urban area. There were 200 seedlings planted, spacing 2 m x 2.5. Technically analyzed the parameters such as plant height, stem gird, leaf number, flower number, and fruit setting. It was also compared with farmers method cultivated around the area. Statistically was analyzed by using t test. Financial analysis used R/C Ratio, BEP, and sensitivity. The results shown that the farming is technically and financially feasible. Moreover, the R/C Ratio 2,86, compared with farmer method 2,21. The benefit gotten for the 200 plants yearly is IDR33,542,000, furthermore, it is an opportunity for the farmer in the area to cultivate papaya merah delima as a main crop. Socially, beside the marketable of the fruit, the city’s consumers are interesting for the shape and the small size appearance.
