GROWTH RESPONSES OF SACHA INCHI BEAN SEEDS (Plukenetia volubilis L) ON VARIOUS ORGANIC MATERIAL SOURCES

Abstract

Sacha inchi is a creeping perennial herb plant that belongs to the Euphorbiaceae family. Sacha inchi, or Plukenetia volubilis is a perennial plant with large, oil-filled seeds. sacha inchi plants began to be widely cultivated. However, in practice it is still planted directly in the field, without going through the nursery first, so the quality of the plants produced varies greatly. Seeding is a process that determines the quality of the plants to be cultivated. Planting media is the media used to grow plants, where roots or roots will grow and develop. A good planting medium must meet requirements such as not containing pest and disease seeds, free of weeds, able to hold water. This study aims to see the effect of the mixture and to get the best mixture of organic matter that supports the growth of Sacha inchi seedlings. This research was conducted from June to August 2022. The research method used was a Randomized Block Design (RAK) with 5 treatments consisting of: Top soil : sand (A), Top soil : sand : burnt husks (B), Top soil : sand : goat manure (C), top soil : sand : bamboo leaves (D), top soil : sand : leftover crickets (E). Data analysis with F test and further test with BNT test level of 5%. Giving organic matter shows better growth than without giving organic matter. Mixture of top soil, sand, and crickets growing media showed optimal growth in number of leaves, number of perfectly opened leaves, widest leaf width, longest leaf length, plant height, fresh weight of plants, and fresh weight of roots.
