Pemanfaatan Abu Sekam Padi dalam Meningkatkan Serapan P pada Produksi Tanaman Kedelai (Glycine max L.)

Use of Rice Husk Ash in Increasing P Absorption in Soybean (Glycine Max L.) Production

Abstract

Soybean production in Riau Province has decreased one of the factors that affect the growth and production of soybean plants is nutrients, where phosphorus plays a very important role. Nutrient P is an important element after nitrogen which plays a role in photosynthesis, respiration, cell division and enlargement, root development, formation of flowers, fruits and seeds This study aims to determine the effect of rice husk ash in increasing P uptake on soybean crop production. The study was carried out with a Complete Random Design (RAL) consisting of four husk ash treatments with doses (0, 20, 30, and 40, grams/polybag) with three replicates, so that 12 experimental units consisting of 6 plants were obtained, of which there were 3 samples. The observed variables included analysis of P content in soil and husk ash, flowering age, harvest age, number of pods and weight of 100 seeds. The results showed that the application of husk ash had a real effect on the harvest age and the number of pods/sample plants at a concentration of 40 grams/polybag, but had no real effect on the flowering age and weight of 100 seeds.
