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

The study aims to determine the effect of planting distance and types of manure on the growth and biomass of Indigofera plants. The study was conducted in practice garden of Faculty of Agriculture UPN “Veteran” Yogyakarta, is a field experiment using a Complete Randomized Group Design consisting of J1: planting distance 1 m x 1 m ; J2: 1 m x 1,25 m ; J3: 1 m x 1,5 m ; J4: 1 m x 1,75 m. The second factor is types of manure, which consist of: M1: cow manure dosage 20 t/ha; M2: goat manure dosage 20 t/ha. The study result shows that there is no interaction between planting distance and types of manure toward growth and biomass yield of Indigofera plant. The planting distance treatment of 1 m x 1 m (J1) and planting distance of 1 m x 1,5 m (J3) gives insignificant influence on all parameters observed at 9 weeks observation after planting. The manure types treatment gives insignificant difference on all observed parameters.Keyword: planting distance, manure, indigofera

Abstract

This research aims to find out the influence of toping on each melon tree towards the yield of melon, and the influence of the use of various growing media compositions towards the yield of melon. This research is conducted in green house at Kaliurang Street km 16.3, Umbulmartani, Pakem, Sleman Regency, the Special Region of Yogyakarta. The research was held when august to October 2017. The research method used is Field Trial which is arranged by using Complete Randomized Design with two treatment factors and is repeated three times. The first factor is the use of growing media in the form of husk charcoal and zeolite (100% : 0%), (85% : 15 %), (70% : 30%), and (55% : 45%). The second factors are performing toping and not performing toping. Based on the analysis, it is shown that there is no interaction between growing media composition and toping treatment based on growing parameters or yield. The growing media composition with husk charcoal and zeolite (85% : 15%) shows a good result in affecting the parameters of fruit weight and fruit diameter. Toping treatment gives a good result for the parameters of fruit weigh, fruit diameter, brix, and flesh thickness.Keywords: melon, toping, growing media composition, hydroponic drip system
