Abstract

Okra (Abelmochus esculentus L. Moench) has a fairly high nutritional content; every 10 gr of young okra fruit contains 33 calories, 7 gs of carbohydrates, 3.2 gs of fiber, and 81 mg calcium. Okra fruit contains a lot of mucilage due to its high fiber content. This study aimed to determine the effect of rock phosphate doses and types of mycorrhizae and the interaction between these two factors on the growth and yield of okra in saline soil. The research results showed that the dose of mycorrhiza had a very significant effect on the growth and yield of okra plants. The best dose of mycorrhiza was 10 g/plant, and the best type was Acauluspora. It showed that a dose of 10 g/plant with the Acauluspora type on okra yields on Ultiisol soil had given the best results in the vegetative phase, which could be seen in plant height parameters 15 and 30 ADP. The dose of rock phosphate is 150 g, which can be seen in the 300 g planting parameter and in almost all the observed variables. Hyphae in the soil can spread widely, which helps absorb more water. The best yields of okra plants were found by applying a mycorrhizal dose of 10 g on fruit weight variables of plants' mycorrhizal colonization on vase vegetative roots and mycorrhizal colonization on plant roots in the generative phase. Keywords: biological agents, fertilizer, mycorrhiza, rock phosphate

Abstract

The success of controlling weeds in soybean plantations, apart from being determined by the type, also determines the dose of mulch. This research aims to obtain the type and dosage of organic mulch to control weeds in soybean plantations. The research was carried out from August to December 2024, in Lawe Sagu Hulu Village, Lawe Bulan District, Southeast Aceh Regency, Aceh Province. The types of organic mulch used are: acacia and kirinyuh, and the doses used are: 0; 4.8; 9.6; 14.4 and 19.2 tons ha-1. The design used was a bifactorial randomized block design with 4 replications. The variables observed were: plant height, number of leaves, root wet weight and plant wet weight. The results of the research show that the kirinyuh type of organic mulch can increase plant height during the 20th and 30th daily periods. An organic mulch dose of 14.4 tons ha-1 can increase the height of soybean plants for the 20, 30 and 40 daily periods and increase the wet weight of soybean plants for the 20, 30, 40 and 50 daily periods. A dose of 19.2 tons ha-1 can increase the wet weight of roots for 20 daily periods. There was no interaction between the type and dose of acacia and kirinyuh organic mulch on the observation of soybean plant growth.

The variables observed were: number of pods, number of seeds, seed weight, weight of 100 seeds and dry seed yield. The research results showed that an organic mulch dose of 19.2 tons ha-1 could increase the number of pods, number of seeds, seed weight and dry seed yield. Independently, the type of mulch and the interaction between type and dose had no effect on the observed soybean crop yields.

Abstract

Coffee plants are annual plants and chili plants are seasonal plants that can usually grow together. The morphology of coffee and chili plants consists of several main components, namely consisting of roots, stems, leaves, flowers, fruits and seeds so as to optimize the implementation of this research conducted in Pedemun Village, Lut Tawar District, Central Aceh Regency from March to April 2023. This research was conducted using descriptive survey method. Sampling was determined by purposive sampling using 4 types of traps, namely yellow plate traps, net traps, sweet juice and pheromones. Insect observations and sampling were carried out at one time period, namely 07.00-09.00 every one week, in sunny or non-rainy weather conditions. Observations were made by identifying trapped predators, and collecting them according to the type of predator, and preserving each predator sample.Based on the observations made, there were 152 predator individuals belonging to 14 species, of which in the order Diptera family syphidae many trapped pest predators are 53 individuals and in the order Diptera family tachinidae 31 individuals and found junga predators in the order hemittera family lygaeldea 22 individuals in the order coleoptera family coccineliit 18 individuals, which occupy the most trapped predators. The results of the study are known from the number of 14 predator species found in coffee and chili plants, the data of the diversity index of predatory insect species is 1.92 which shows the category of moderate diversity. Of the 14 species of predators of coffee and chili plants, the most predators caught were syiphid flies as many as 53 individuals, on average attacking pest plants on coffee and chili plants
