Abstract

To mitigate the impact of extreme weather incidents, rice cultivars Way Seputih (WS) and Way Apo Buru (WAB) were evaluated under simulation of continuous wind and rainfall treatments. The research was conducted from July to October 2017 at Leuwikopo Experimental Farm, Bogor, Indonesia. For 15 days at day time, flowering rice hills were treated with about 100 mm/h water shower (Experiment-1), and with 0, 10-15, 20-25 and 35-40 km/h wind velocity (Experiment-2). Results showed that wind and rainfall treatments reduced rice production; the effect depended on the genotypes and flowering stage. Rain treatment from panicle emergence to 50%-emerged increased the number of unfilled grains by 154.6-182.3% and 55.7-101.9% in WS and WAB cultivars, respectively. Rain treatment at 100%-emerged had no effect on WS, but it increased unfilled grain (163.5%) and decreased grain index (12.9%) in the WAB cultivar. Wind speed at 35-40 km/h promoted a high percentage of grain drop (25.7%) and unfilled grains (77.3%), and low grain index (20.8 g) in WS genotype. WAB was more tolerant of wind stress than the WS. The present experiment showed that genotype had different responses to wind and rain treatments implying different mitigation strategies should be applied through genotype selection.

Abstract

Soybeans are one of the main food crop commodities, which have high nutritional content, especially the protein content contained in soybean seeds. Population increases and soybean production areas become narrower, so farmers can plant various superior varieties of soybeans. The aim of this final assignment is to determine the yield of soybean production from five varieties. The morphology of these five varieties is different, namely in roots, leaf shape, stems, flower color, pods and seeds. Superior varieties have superior properties compared to local varieties, so superior varieties can increase soybean production. This final assignment will be carried out from February to June 2023 at IP2TP Jambegede under the auspices of the Various Nuts Plant Standard Instrument Testing Center (BPSIT), Malang, East Java. The varieties observed were the Dega-1, Dena-1, Dena-2, Devon-1, and Devon-2 varieties, by observing plant height, number of branches, weight of filled pods, number of filled pods, number of empty pods, weight of 100 seeds, number of fertile nodes, plant growth, seed weight. Based on the weight of the production results observed, the Dega-1 soybean variety had the largest weight and Dena-1 had the smallest weight. Of the number of tiled plants that grow, the Dega-1 variety is the variety that has the most plants and the tiles that grow the least are Dena-2. Keywords: production, soybeans, varieties

Abstract

Rice is the main staple food for most Indonesians. Rice consumption in Indonesia is increasing along with population growth. Efforts to increase rice production continue to be carried out. Increasing production using external inputs in the form of chemical fertilizers and pesticides has resulted in a decrease in food quality and land degradation. Meeting food needs must be harmonized with environmental sustainability. Organic rice cultivation can improve the quality of agricultural products and be friendlier to the environment. This research aims to determine the quality of rice and the nutritional content of three rice genotypes cultivated organically and non-organically. The research was conducted at the Politeknik Negeri Lampung, in August 2022- April 2023. The research results showed that the quality of rice from three rice genotypes (red, white, black) in the organic cultivation system met the Premium Quality requirements, while in the non-organic cultivation system it met the Medium Quality requirements I SNI 6128:2020. The nutritional quality of the three rice genotypes was not significantly different in organic and non-organic cultivation systems Keywords: organic rice, brown rice, black rice, white rice, SNI 6128-2020

Abstract

Edamame is a type of soybean that is large in size and is harvested when it is still fresh and young. The fresh green color of edamame seeds and their sweet taste differentiate edamame soybeans from ordinary soybeans. The quality of edamame yields is one of the determining factors for the success of edamame cultivation. The aim of this research was to determine the physical quality, texture and level of damage to edamame at various harvest ages. The research was structured using a complete randomized block design with 5 treatments, each treatment having 4 replications. Research data were analyzed using ANOVA and tested by Fisher's LSD test at a significance level of 5%. The results of the research show that harvest age influences the texture, weight, size and level of damage to edamame pods. Based on the weight of the pods per plant, the best harvest age for edamame plants is 72 HST with a potential yield of 16.38 ton.ha-1, a texture value Edamame is a type of soybean that is large in size and is harvested when it is still fresh and young.
