Abstract

Grammatophyllum speciosum is the largest orchid species which lives epiphytically on the trees in the forest. The rate of natural propagation of Grammatophyllum speciosum is very slow. The objective of the research was to determine the effect and the best concentration of rice water and BAP for the multiplication of Grammatophyllum speciosum shoots. The research was a single factor experiment arranged in Completely Randomized Design with several types of multiplication media as treatments. The treatments were MS + 0.5 mg/l BAP, ½ MS + 25% rice water + 0.5 mg/l BAP, ½ MS + 50% rice water + 0.5 mg/l BAP, ½ MS + 75% rice water + 0.5 mg/l BAP, ½ MS + 100% rice water + 0.5 mg/l BAP, MS + 1 mg/l BAP, ½ MS + 25% rice water + 1 mg/l BAP, ½ MS + 50% rice water + 1 mg/l BAP, ½ MS + 75% rice water + 1 mg/l BAP, and ½ MS + 100% rice water + 1 mg/l BAP. Each treatment was replicated ten times. Variables observed in this study were survival rate, browning rate, contamination rate, the percentage of explants sprouting, the increase of shoot height, number of shoots and leaves, the percentage of rooted explants and the number of roots. The data were analyzed by using Analysis of Variance at α=5%. The results showed that various concentrations of rice water and BAP were able to multiply the shoots and affect the shoot growth and root length of Grammatophyllum speciosum. The combination of 75% rice water + 1 mg/l BAP on ½ MS medium was the best treatment for Grammatophyllum speciosum multiplication

Abstract

A field research to observe the effect of kinds of organic manure and on growth  and yield of sweet  corn  was  done  in Danguran   village,  Klaten  Regency  of Midle Java. The research was conducted during August to October 2003. The field experiment was arranged in a Randomized Complete Block Design, with 3 replications. The kinds of organic manure treatment consisted of 5 levels which are: no farm manure (PKO), chicken farm manure (PKl), vermicompost or Kascing (PK2), cow farm manure A (PK3), and cow farm  manure-B (PK4). Each organic matter given was 10 ton /ha. The result showed that the chicken farm manure gave the significantly higher growth and yield  of sweet  corn  than  the others.  The average sweet corn yield obtained in this research was 16,2 ton/ha.

Abstract

The study investigates the efficacy of nano-sized cattle bone ash as an alternative phosphorus source for shallot cultivation, aiming to reduce dependence on mined phosphate rock. The experimental study was arranged in a 4 x 3 factorial Completely Randomized Design. The first factor was the recommended dose of P fertilizer, consisting of 100%, 80%, 60%, and 40%. The second factor was using nano cattle bone ash as a foliar application, applied 3, 4, and 5 times. The observation was made on the plant growth and yield of shallot. Data analysis was conducted with an ANOVA and continued with the DMRT. The results showed no interaction effect of the dose of P fertilizer and the frequency of spraying nano cattle bone ash on the growth and yield of shallots. The application of P fertilizer at 40% of the recommended dose could already produce shallots that were the same as the application of P fertilizer according to the recommended dosage. The spraying frequency of three times was able to provide high shallot yields.  In the future, it is expected that spraying cow bone ash with nanotechnology can be applied three times with a 40% recommended dose of P to increase fertilization efficiency.
