Abstract

Candlenut is an important plant which has the potential to produce biofuels. Therefore, it is necessary to create a technological innovation in the cultivation of this plant in order to obtain a good vegetative growth. Thus, the generative growth become well and the plant become productive by giving chitosan, an organic fertilizer made from natural ingredients derived from shrimp shells which is processed by radiation technology to produce useful agriculture products. The aim of this research was to determine the interactions between method and frequency of Chitosan application. To factors Randomized Block Design was used as methods in this research. The first factor was Application methods of Chitosan (Pouring around near the roots, Spray to the leaves, and spray onto the stem ). The second factor was Frequency of chitosan application ( three, four and five times). As a comparation was without chitosan treatment. The result showed that there was no interaction between the treatment method and the frequency of chitosan distribution towards the vegetative growth of Reutealis trisperma (Blanco). When chitosan was sprayed onto the leaves, it gives better effect than pouring around near the roots and sprayed onto the stem. The frequency of chitosan application for three times was the best one. Plants that were treated with chitosan have better vegetative growth than those without chitosan treatment.Keywords: Candlenut, chitosan, vegetative growth

Abstract

Sorghum is one of the commodities that are potentially very good to meet the needs of food, feed, industrial and renewable energy sources. Sorghum has protein, iron and calcium content that is much higher than rice. Additionally, sorghum has wide adaptability and is a plant that is tolerant to drought and low fertility. Therefore it can be cultivated on marginal lands. This study aimed to study the effects of fertilization on the growth and brix value of sweet sorghum cultivated on marginal land. The experiment was arranged in randomized completely block design, with three treatments, namely NPK, NPK + LOF (Liquid Organic Fertilizer) / 1 week, NPK + LOF/ 2 weeks. Each treatment consisted of 5 replication, and for each replication 6 plant samples was observed. Each plot consisted of 12 rows and in each row there were 7 plants. Sorghum was planted with the distance between rows 75 cm and the distance between plants in rows was 30 cm. The data was subjected to analysis of variance followed by Duncan’s Multiple Range Test. The application of NPK fertilizer plus LOF once a week resulted in significantly higher plant height, number of leaves and brix value compared to NPK fertilizer plus LOF fortnightly or just NPK fertilizer alone. Fertilization treatment did not significantly affect sorghum stem diameter, except at the age of 3 weeks after planting.Keywords: fertilization, growth, brix, sweet sorghum.
