One of the roles of weeds as allelopathy because weeds release chemical compounds that can inhibit growth and kill plants around them. This study aimed to determine the effect of concentration of ‘bandotan’ plant extracts plants at various application times on the growth and yield of mustard. The research was carried out at the Greenhouse of the Faculty of Agriculture, Pattimura University, from November 2017 to January 2018. This study used an experimental method with a completely randomized design (CRD) involving two factors and with three replications. The first factor was ‘bandotan’ extract with 4 concentration levels: control (no extract), 100 g/L, 200 g/L and 300 g/L. The second factor was application time with three levels: 5 days after planting (DAP), 10 DAP, and 15 DAP. The variables observed included plant height, leaf number, leaf area, fresh crop weight, and crop dry weight. Data analysis of each variable was conducted using the analysis of variance. If there was a significant treatment effect, it proceeded with the Tukey test at the level of α = 0.05. The results showed that the concentration of ‘bandotan’ extract did not significantly affect all observation variables (plant height, leaf number, leaf area, fresh crop weight, and dry weight of mustard). Time of ‘bandotan’ extract application did not significantly affect all observation variables (plant height, leaf number, leaf area, fresh crop weight, and dry weight of mustard).

The purpose of this study was to assess the presence of soil water and to determine the growing season in the Saumlaki area based on two rainfall conditions. This study used monthly rainfall data for 30 years (1990-2019) as well as other climatic data, such as air temperature, air humidity, sunshine duration and wind speed for 15 years (2005-2019). Computing of the water balance was carried out using Thornthwaite-Mather Method, and determination of growing season using soil water in optimum condition. Based on the calculation of the land water balance in the rainfall conditions there was a 75% chance of being surpassed by the groundwater deficit in the Saumlaki area which lasted for 6 months (June- November), whereas the value increases by 183 mm or 45.52% compared to normal conditions, that was from 402 mm to 585 mm. On the other hand, the groundwater surplus lasted only a month (May) and tended to decrease by 686 mm or 97.03% compared to normal conditions, from 707 mm to 21 mm. The optimum soil water content for plants in rainfall conditions was 75% chance of lasting for 6 months (January-June); 2 months shorter than the normal 8 months (December-July).

Maize cultivation is faced with various plant diseases, that can reduce the quantity and quality of crop yield. Plant disease is one of the limiting factors for crop production and seed quality. One of the most harmful maize diseases is blight or midrib rot caused by the soil-borne fungus Rhizoctonia solani. The aim of the study was to obtain endophytic microorganisms in maize and to test the antagonistic ability of these fungi as biological control agents against R. solani. The study took place in January-September 2018 in the field and the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, University of Pattimura. Endophytic fungi isolated from maize plants from the roots, stems and leaves. Samples were cleaned in running water and air-dried. Subsequently, the samples were sterilized using 70% alcohol and immersed in sodium hypochlorite solution for 2 minutes and rinsed with sterile water 3 times. The sterilized roots, stems and leaves of maize were peeled, cut to a size of ±5 mm, split and dried on sterile filter paper. Sterile samples were grown on PDA culture media at four points and incubated at room temperature. Visual identification was carried out with the aid of a microscope on fungi growing on the culture media. The results showed the presence of the endophytic fungi Trichoderma sp., Aspergillus sp., Penicillium sp., Diplodia sp. and Mucor sp.

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 research objective was to study the effects of rainfall on the formation of flowers and fruits of S. malaccense. The research was conducted at the Aripan Experimental Garden, Indonesian Tropical Fruit Research Institute, from August 2015 till February 2016. Observations were made on three flowering periods. This research was a descriptive experiment, the results were shown in the form of the average data and growth charts. Flowering initiation of S. malaccense was stimulated by the length of the dry period. The highest percentage of fallen out flowers occurs during the rainy season. Fruit size increases along with heavy rainfall. Total soluble solids decrease when rainfall is high. \u0000Keywords: flowering, rainfall, Syzygium malaccense \u0000  \u0000ABSTRAK \u0000Informasi tentang pembungaan dan perkembangan buah jambu bol dibutuhkan dalam merencanakan produksi dan perawatan tanaman.
