Abstract

This research is an experimental study that aims to examine the combination of cattle manure, humic acid, and mycorrhizae to increase mycorrhizal infections in the roots of chili plants in the Udipsamments soil in Puger District, Jember Regency, which was carried out in May-November 2018. The research design used was a factorial complete randomized block design with 3 factors that were repeated 3 times. The first factor is cattle manure (0 tons / ha, 10 tons / ha, 20 tons / ha), the second factor is humic acid (0 ppm / ha, 200 ppm / ha), and the third factor is mycorrhiza (0 g / plant , 30 g / plant). The results showed that the combination of cattle manure, humic acid, and mycorrhiza inoculants to chili plant roots was able to increase the root mycorrhizal infection of chili plants and increase the nutrients available in the soil by 191.84% for nitrogen and 392.93% for phosphorus.

Abstract

Sidodadi village, Tempurejo sub-district is one of the villages in the southern part of Jember Regency. The majority of the population works in the agricultural sector. The village is known as an agriculture-based village in Jember Regency. The “Ngudi Rejeki” Farmer's Group in Sidodadi Village, Tempurejo District, Jember is constrained by the problem of increasing non-subsidized fertilizer prices which makes it an obstacle in increasing agricultural yields. On the other hand, the regulation of subsidized fertilizers is quite limited among farmers so that it is suspected that it will increase production costs. The results of direct discussions with partners revealed an interesting fact that the average use of chemical fertilizers is very high even though currently the use of organic fertilizers can reduce production costs with the basic ingredients for making fertilizers derived from agricultural production residues. This area has a lot of waste rice straw and cow dung that has not been utilized. Some of the solutions offered to deal with partner problems include socializing the use of organic fertilizers, one of which is trichocompost fertilizer as a substitute for the use of chemical fertilizers, demonstrations on how to make trichocompost fertilizer with cow dung as raw material with the biodecomposer Trichoderma sp. This extension activity is carried out with a participatory approach, which means that farmers as extension participants are actively involved in the activity. The method used in the implementation of community service is socialization, discussion, and demonstration of making trichocompost fertilizer. The results of the socialization of trichocompost organic fertilizer obtained as many as 77% of farmers interested in using trichocompost fertilizer as soil improvement fertilizer.

Abstract

Tomato farmers in Indonesia face challenges such as unpredictable weather conditions that can affect crop yields. Climatic stress, such as drought and heat, can have significant effects on plant growth. Plant Biostimulant have been shown to alleviate climatic stress in plants by modifying physiological processes and enhancing stress tolerance, ultimately improving crop growth and productivity. Recently, weed extract can serve as a biostimulant to improve growth and productivity of crops. This research aimed to determine the best concentration of weed extract-based biostimulant (WEBB) to increase tomato growth and production in dry season. The research was conducted on June to September 2024 in Tutul Village, Balung District, Jember Regency. The research used Randomized Block Design consisted of five levels of WEBB concentrations, i.e. 0, 1, 2, 3 and 4 ppm. The concentration of WEBB at 1 ppm significantly increased early growth of stem and the number of leaves at 2 WAP by 16.39% and 39.02% respectively. The application of WEBB at 1–2 ppm also showed a significant increase in the number of fruits by 24.49% compared to control. This indicated that 1 ppm WEBB were effective in stimulating the early growth and fruit formation on tomato plant.
