Abstract

The aim of this study, was to determine the effect of spacing and number of seeds per planting hole on the vegetative phase of local Sumbawa rice plants in paddy fields. This research was conducted for 3 months. This study, used quantitative method with factorial randomized block design (RBD) with 2 factors, namely are the use of spacing (J) and the number of seeds per planting hole. Each treatment was repeated 3 times. The factor of using spacing consists of 2 levels and the factor of number of seeds per planting hole consists of 3 levels. The results of the analysis showed that the combination treatment had an effect on the spacing and number of seeds per planting hole had a significant effect on the parameter of the number of tillers. The single factor of spacing has a significant effect on the parameter of the number of tillers. The single factor of the number of seedlings per planting hole had a significant effect on the parameter of the number of tillers.

Abstract

The aim of this study was to determine the effect of the composition of the planting medium of sawdust and rice husk on white oyster mushroom (Pleorotus ostreatus). The study was conducted using experimental methods, Completely Randomized Design (CRD) consisted of 5 treatments, which each treatment consisted of three replications. The treatments consisted of SP1 = 100% sawdust + 0% rice husk; SP2 = wood powder 75% + rice husk 25%; SP3 = 50% sawdust + 50% rice husk; SP4 = 25% sawdust + 75% rice husk; and SP5 = 0% sawdust + 100% rice husk. Observational data were analyzed using ANOVA at 5% significance level, if the results of data analysis showed significant differences, then further tests were carried out using the Least Significant Difference Test (LSD) at 5% significance level. The results of data analysis showed that the fastest of mycellium spread time was in the SP5, which was 24 days after inoculation. The fastest of pin head appearance time was found in the SP3, which was 88 days after inoculation. The heaviest fruit weight was found in the SP3 treatment and the lowest fruit weight was found in the SP5.
