Abstract

This study aims to examine the effect of concentration of liquid organic fertilizer supermes on various spacing to the growth and yield of onion. The experiment was conducted in Dusun Telaga Kodok, Hitu Lama Village, Leihitu Barat District, Central Maluku District, from March to April 2017. The experiment used was a Randomized Block Design with three replications. The concentration of liquid organic fertilizer supermes consists of: 0, 2, 4, 6 mL/L water. Plant ing distance consists of: 10 × 15 cm, 15 × 15 cm and 20 × 15 cm. Varieties used were varieties of Bima Brebes. Parameters measured were plant height, number of leaves, number of tubers, root length, wet weight and dry weight of tubers. During the experiment, rainfall and rainy days were quite high at the research location. This condition causes the crop to be harvested at 41 HST because it is attacked by ground caterpillar, mosaic disease and purple spots. The application of liquid organic fertilizer has not shown any significant effect to the growth and yield parameters of shallot crop. Planting distance of 15 × 15 cm shows the effect on plant height and number of leaves at 35 HST, tuber weight and tuber dry weight and there is a significant interaction on the leaf number at 35 HST with concentration of 4 mL/L water and Planting Distance 15 × 15 cm. Keywords: liquid organic fertilizer, planting distance, red onion ABSTRAK Penelitian ini bertujuan untuk menguji pengaruh konsentrasi pupuk organik cair supermes pada berbagai jarak tanam terhadap pertumbuhan dan hasil bawang merah.

Abstract

One of the environmental factors that affect cassava productivity is climate/weather. Climate change has the potential to have an impact on various sectors, one of which is the food crop sector. Cassava is one of the local food commodities in Ohoi Wain that is at risk of being affected by the impact of climate change. This study aimed to identify the dominant climate factors affecting cassava production, assess farmers' adaptation strategies to climate change and analyze the impact of climate change on production and farmers' income. The method used was descriptive analysis method used to analyze the dominant climate factors affecting the production of cassava and the adaptation strategy adopted by farmers, algebraic averaging technique for rainfall analysis, quantitative analysis for analyzing farmers' income and regression equations to see the relationship between rainfall and cassava productivity. The results showed that the climatic factor that most dominantly influenced the production of cassava was rainfall. The adaptation made by farmers to climate change was by changing planting time, minimum tillage, selecting superior varieties and applying organic mulch. Climate change, marked by a decrease in rainfall in 2015, caused the productivity of cassava to decrease by 46,4% and farmers' income to increase by 11,45%. The decrease in rainfall had a very significant effect on the decrease in the productivity of cassava or had a strong relationship, which was shown by the correlation coefficient value r = 0,04731 and a high level of accuracy with R2 = 89,2%. Keywords: adaptation, climate change, cassava production, income ABSTRAK Salah satu faktor lngkungan yang berpengaruh terhadap produktivitas ubi kayu adalah iklim/cuaca.

Abstract

Waste derived from plant material can be used as a source of plant nutrients. These waste products can be processed into compost to increase soil organic matter. The study aimed to determine the effect of cocoa peel ash application on drought conditions and natural sources of potassium for the growth and production of maize plants. The research design is a Factorial experiment in a Completely Randomized Design consisting of two treatments, namely: the amount of water application equivalent to rainfall (R): (R1) 70 mm / month, (R2) 80 mm / month, and (R3) 90 mm / month; fertilization of cocoa skin ash (K): control (K0), 100 kg/ha (K1), 150 kg/ha (K2), 200 kg/ha (K3), and, (K4) 250 kg/ha repeated 3 times. The results showed that the interaction between cocoa bark ash fertilization and the amount of water application equivalent to rainfall had a very noticeable effect on plant height and leaf area variables, while stem diameter changes had a noticeable effect. Fertilization treatment of 250 kg/ha (K4) best affects plant height, stem diameter, leaf area, and dry weight. The dose of cocoa husk ash fertilization of 200 kg/ha gives the best results on the weight of the seeds per plant, while the dose of 150 kg/ha is best at the weight of 100 seeds. Treatment of the amount of water application equivalent to rainfall of 90 mm/month gives the best results on leaf area, seed weight per plant, weight of 100 seeds, dry weight of plants, and harvest index
