Abstract: Currently, the chemical agrochemicals including fertilizers and pesticides were used very much on green onions, leading to contamination of agrochemicals on agricultural products, soil and water and seriously affecting consumer health, the environment and ecology. Therefore, the research focused on using microbial and biological products in the cultivation and production of green onion in order to limit the use of inorganic fertilizers and pesticides, contributing on improving the value of onions is really necessary. The objective of the study was to evaluate the efficacy of salt tolerant bacterial product, NPISi containing biologically nitrogen fixing, phosphate solubilizing, IAA synthesizing, and Si solubilizing bacteria in a combination with spraying plant protection biological product (PPBP) from garlic, chili, ginger, lemongrass, anise, and cinnamon on growth, yield, pest and disease control ability on green onion, and soil properties in Tran De district, Soc Trang province, Vietnam. The experiment was arranged in a completely randomized block design with 8 treatments and 4 replications on the in two consecutive crops. The results showed that the treatment applied of 80 kg/ha of NPISi inoculant combined with 6% PPBP sprayed every 10 days enhanced plant height, number of buds/hill, number of leaves/hill, stem diameter and yield of green onion up to 45% as compared to the control treatment received the same amount of recommended NPK dose. Moreover, the treatment applied with NPISi and PPBP in combination with 50% NP + 100% K had green onion yield equivalent to the treatment received recommended 100% NPK fertilizer after two consecutive crops. Besides, the use of NPISi inoculant and PPBP also improved pH and the number of bacteria in soil. Concurrently, the use of PPBP also effectively controlled of the tube borer numbers on green onion.

Abstract: Farmers cultivate potatoes intensively in the upper Lembang watershed, i.e. cultivate the land every planting season. The soil management system does not apply soil conservation methods, so it is suspected that there has been a decline in soil fertility. The purpose of this study was to examine the soil properties of potato farming in several land forms. The method used is the land survey method. Soil sampling was done by purposive random sampling and descriptive. Soil samples taken were disturbed soil samples for analysis of soil physical properties (texture, bulk density, total pore space, permeability) while direct measurements in the field were effective soil depth and infiltration rate. Meanwhile, undisturbed soil samples were used to analyze the chemical properties of C-organic soil. Soil analysis was carried out in the laboratory of the Department of Soil, Faculty of Agriculture, Andalas University. To determine the soil characteristics of the landform is to analyze the soil parameters using Minitab 17 software. The results showed that the value of soil erodibility in the production center area is strongly influenced by c-organic variables, dust, bulk density, total pore space, fine sand fraction, fraction clay and soil permeability. The value of soil erodibility includes low to moderate criteria. It was concluded that the soil condition was still quite good.

Abstract: Rice is a main field crop in Fogera rain fed lowland ecosystem as stable food and straw is mainly used for cattle feed. Weed is a major constraint for rice production causing a subsequent drastic reduction of yield. Manual weeding method is extremely labor intensive and time consuming which conveys to high cost of production. The study ambition was to test different mechanical weeders with farmers to acquire their preference. Pertaining to this, four prototype mechanical weeders were developed and evaluated under rainfed lowland rice production ecosystem at Fogera. The recommended planting space of rice in the experimental area was 20cm between rows and mechanical weeders were developed 18cm wide. The rice was sown in rice field with 20cm row spacing which allows for the use of manual weeders. On the first day, one representative farmers field was identified for evaluation. The researchers together with DA’s went to the village and selected 30 farmers who had willing to participate in the evaluation practice in the following day. Before selection, farmers were asked generally whether they are volunteer to participate in this weeder evaluation activity in their own rice field or not. Based on this information, the targeted number of women and men were selected. Rotary weeder, star rotary weeder, finger-push weeder and push weeder were developed and gauged to get farmers preference. Selected weeders were gender sensitive and equal number of men and women were participated in the evaluation of mechanical weeders. Data on cropping system, crop establishment method, weed infestation and type, weeding efficiency, effective field capacity and damaged plants were collected. From this evaluation activity, two mechanical hand weeders rotary weeder and finger-push weeder were selected and distributed to farmers for future use. Women were selected finger push weeder while men have selected rotary weeder. The maximum weeding efficiency (90.2%) was observed from the rotary weeder whereas the weeding efficiency of finger-push weeder was (82.8%). However, push weeder had provided (51.3%) weeding efficiency while star rotary weeders brought (42%) of weeding efficiency. The least cost but high-cost reduction amongst the mechanical hand weeders were found from the rotary weeder while the highest cost and minimum cost reduction were attained from the push weeder. Rotary weeder and finger-push weeder generate to decrease the total cost and express very effective weeding technologies in the clay soil and ponded water level for aquatic and grass weeds in the testing sites.

Abstract: Mungbean is one of the most important pulse crops, grown from the tropical to sub-tropical areas around the world. In Ethiopia, almost half of the land mass lies with in warmer and lowland areas, with ample water resources and exploited less due to the major focus of crops production on mid to highland areas of the country receiving ample annual rainfall. In order to test the adaptability of mungbean in the lowland irrigated areas of Ethiopia, the current study was conducted at Werer research center, with the objectives to identify, select and recommend adaptable, high yielding and tolerant mungbean varieties, for irrigation production system in the lowland areas of middle awash rift valley, and at the same time assessing suitability of the area for Vigna radiate production. Five mungbean varieties were used in the study for two consecutive seasons (2019 and 2020). Result from the ANOVA revealed that, significant varietal differences were observed for all of the studied parameters in both seasons, except for grain filling period in the first season. The varieties Chinese, Showa-Robit and NVL-1 flowered and matured early at both growing seasons among the tested mungbean varieties. Grain yield was positively and significantly correlated with number of pods plant-1, number of seeds pod-1 and biomass weight, and negatively correlated with phonological characters. The maximum grain yield coupled with better number of pods plant-1 and seeds pod-1 was noted for the varieties N-26 and NVL-1 in the first season and Chinese and NVL-1 in the second season. Generally, mungbean varieties tested for their adaptation under this Great Rift Valley region having warmer air condition respond well and thus the area can be characterized as suitable for production of mungbean using irrigation water.
