Abstract

Jatropha curcas L.) is one of the vegetation that produces energy and is often used as biodiesel in an effort to reduce the use of fossil energy that has limited reserves, cannot be renewed (Unrenewable) and has emissions of combustion gases (pollutants) that cause environmental impacts such as the greenhouse gas effect and affect air quality. This experiment was carried out at the Experimental Garden of the Faculty of Agriculture, Winaya Mukti University, Sumedang Regency. The altitude of the place is 850 m above sea level. The trial time is from September to October 2022. The purpose of the experiment was to study the interaction between FMA dosing and cytokinin concentration against increasing growth of IP-3P cultivar jatropha plants in medium plains and obtain the best FMA dosing treatment and cytokinin concentration on IP-3P cultivar jatropha plant growth in medium plains. The study used a randomized group design (RAK) factorial pattern, which consisted of two factors, namely FMA dose with levels: 0 g, 5 g, 10 g, 15 g, 20 g and cytokinin concentrations with levels: 0 MgL-1, 150 MgL-1, 300 MgL-1, 450 MgL-1, 600 MgL-1. Each treatment factor consists of 5 levels. Each treatment is repeated twice, then the total amount of 5 x 5 x 2 = 50 plots. The results of the experiment showed an interaction between FMA dosing and cytokinin concentration on the constraint parameters of the stomata, the number of leaves and the diameter of the stem. It was found that the treatment of FMA dose level f3 (15 grams) gave the best results on the parameters of mycorrhizal colonization, leaf chlorophyll, plant height, number of leaves, number of lateral branches, and root weight + FMA. In the treatment of cytokinin concentration level s3 gave the best results on the parameters of mycorrhizal colonization, leaf chlorophyll, as well as the number of leaves

Abstract

The research was carried out in the rice fields of Jaya Mukti Village, Blanakan District, Subang Regency, with a height of 10 meters above sea level and a type of rainfall (Appendix 1). The trial will be carried out from August 2022 to November 2022. This study aims to learn about the interaction of the influence of N, P, K fertilizer and biological fertilizer doses on the growth and yield of Grendel rice paddy crops. This experiment uses a Random Group Design (RAK) experimental design of a factorial pattern consisting of two factors, the first factor is 3 levels of N, P, K (p) fertilizer and the second factor is Biological Fertilizer (h) as many as 3 levels, both factors are repeated 3 times. There were 9 treatment combinations that were randomly placed on each replicate. The results of the study showed that the administration of N, P, K fertilizer and biological fertilizer had an effect on growth (plant height 21 DAP and number of saplings 28 DAP), yield (grain weight per clump). The application of N, P, K fertilizer has an effect on the yield components (number of productive saplings, panicle length and weight of 1000 grains). The N,P,K dose of 60 % indicates the best panicle length and weight of 1000 grains. A dose of 30 kg ha -1 biofertilizer showed good results on plant growth
