Abstract

Response of Long Beans (Vigna sinensis L.) Due to Dosage Treatment of Compost Fertilizer from Cocoa Fruit Peel. The research was conducted in the Experimental Garden of the Faculty of Agriculture, University of Flores, Lokoboko Village, Ndona District, Ende Regency from June to August 2020. The purpose of this study was to determine the effect of cocoa husk fertilizer dose on the growth and yield of long beans. Using Randomized Block Design (RAK). With 5 doses of cocoa pod compost, namely: D1 : without treatment of cocoa pod skin or 0 g/plant, D2 : 5 tons per hectare of cocoa pod compost, D3 : 7.5 tons per hectare of cocoa pod compost, D4 : 10 tons per hectare of cocoa pod compost. D5 : 12.5 tons per hectare of cocoa pod husk compost. Each treatment was repeated 4 times, so that 20 trials were obtained. The application of cocoa husk compost fertilizer on long bean plants was proven to have a very significant effect on increasing the number of leaves at the observational ages of 21, 28 and 35 days after planting, leaf area at planting ages 14, 21, 28 and 35 days after planting, number of fruits, fruit weight at planting and weight. fruit per hectare The optimal dose of cocoa pod compost for long bean plants is 250gr per plant or the equivalent of 12.5 tons per hectare (D5) which is able to provide optimal growth and yield of long bean plants with an average percentage increase in the number of leaves aged 21, 28 and 35 by 20.68%; the mean leaf area at the age of 14, 21, 28 and 35 hst was 18.23%, the number of fruit was 27.57%; fruit weight per plant was 36.81% and fruit weight per hectare was 36.81%.

Abstract

The purpose of this research was to examine the response of water spinach plants to the application of bioactive fermented liquid organic fertilizer on plant growth. This research used a method consisting of two treatments and one combination, namely a combination of watering and spraying treatments, as well as watering, spraying, and control. This experimen was conducted in the outdoor laboratory of SMKN 63 Jakarta, on land Kale plants. From this research, it was found that the combination of watering and spraying treatments was significantly higher and gave the best results compared to the watering, spraying, and control treatments. Based on the results of the study, it is known that there are differences in harvest age between the treatments of Watering, Spraying, Watering & Spraying and Control. The fastest harvesting age in the treatment of Watering & Spraying. Bioactive has a positive effect on vegetative growth and has a biopesticide effect. This is presumably because Bioactive is made from organic material/agricultural waste by aerobic and anaerobic fermentation methods so that from the fermentation it produces amino acids and alcohol which have an effect against plant vegetative growth and pests that often appear on crystal guava and breadfruit plants. During and after the experiment, no signs of pests or diseases were seen on the plants.

Abstract

This study aims to determine the relationship between Earthworm Population and C-organic and N-total in Horticulture and Coffee Monoculture cultivation in Nduaria Village, Kelimutu District. This research was conducted using an exploratory method that is carried out by direct observation from the observation location. How to calculate earthworms using the hand sorting method. The method commonly used for the determination of C-organic is the Walkley and Black method, while the method used for the determination of N-total is the Kjehdahl method. This method is used because it is considered simple, fast, easy to do, and requires little equipment. The results of this study indicate that in horticultural land there is no earthworm population found at all depths. Earthworm populations were found at all depths in the coffee plantation monoculture, the highest population was at a depth of 0-10 cm as many as 41 m2, Biomass was 9 g, and Biomass vs Population 0.21 m2. In horticultural fields, the highest c-organic and n-total is at a depth of 0-10 cm, the c-organic value is 3.03% (high criteria) and n-total is 0.47% (medium criteria). The close relationship between the earthworm population, biomass, and biomass versus population was positively correlated with c-organic and n-total in horticultural land and coffee monoculture.

Abstract

This study aims to determine the population and level of attack of mealybug pests on ginger plants during harvesting in Nuamuri Village, Kelimutu District, Ende Regency. This research was carried out from February 2020 to July 2020, in Detubewa village, Nuamaro village and Nuamuri village. Observations were made by directly counting pests and damaged and attacked rhizomes, using the path method. Data analysis used is data obtained from the location of observations in tabulation based on the results of direct observations in the field. What was observed was the population and attack rate of each affected ginger planting location. The results showed that during the observation, the highest population of mealybugs was found in Detubewa village with 2,645 heads and the lowest value was in Nuamaro village, namely 2,127 heads, the highest pest population after Detubewa village was village Nuamuri with 2,478 individuals. Meanwhile, the attack rate and presentation of very heavy attacks were in Detubewa village by 84%, and heavy attacks in Nuamuri village at 66% and Nuamaro village at 68%.

Abstract

The use of mycorrhizal biofertilizers in shoot grafting cacao (Theobroma cacao L.) nurseries is one of the efforts made to increase cocoa growth in Sikka Regency. This study aims to determine the effect of the dose of mycorrhizal biological fertilizer on the growth of cocoa seedlings. The study used a randomized block design (RAK) with fertilizer doses of 0 g/polybag (control), 10 g/polybag, 20 g/polybag, 30 g/polybag, 40 g/polybag 50 g/polybag. The results showed that the treatment the addition of mycorrhizae on shoot grafting cocoa seedlings had no effect on all growth variables observed at 30 days after mycorrhizal application and significantly affected all growth variables for cacao seedlings aged 60 days after mycorrhizal application. Giving mycorrhizae to shoot grafting cocoa seedlings at a dose of 50 g/polybag (M5) gave the highest yield for all growth variables of cocoa seedlings aged 60 days after mycorrhizal application, namely plant height 48.50 cm, stem diameter 1.10 cm, and number of leaves 8 ,25 strands.
