Abstract

Ulin (Eusideroxylon zwageri) is one of the native plants of Indonesia whose growth is spread in tropical forest, among others in southern Sumatra and Kalimantan. Based on the results of the 1998 Asia Regional Workshop meeting held at the Hanoi (Vietnam) International Union for Conservation of Nature and Natural Resources (IUCN), it was determined that ironwood is on Vulnerable A1cd + 2cd status which means sensitive or is facing a high risk of extinction. Tissue culture is a technique that needs to be applied to overcome the problem of ironwood regeneration initiation. However, the concentration of tannin with high concentration so that the formation of browning which leads to the death of ulin tissue is one of the causes of the low success of ironwood tissue culture. This study was formulated based on the potential of activated charcoal and vitamin C to overcome browning, so that it can significantly affect the growth of Ulin regeneration initiation (Eusideroxylon zwager). The analytical method used is Observation of Qualitative Parameter Treatment, namely explant color and the quantitative parameter observed is the number of explants that have browned and not browned in this case are calculated in percent. Based on the results of the research that has been done, obtained methods to overcome browning in ulin explants (Eusideroxylon zwageri) which is divided into 2 stages. In stage 1 (pre-condition) browning can be overcome with a 100% success rate, explants soaked for 24 hours in 50% MS liquid media with pH 4. In stage 2, browning can be overcome with a 100% success rate on 100% MS solid media addition of BAP 1.0 mg / L with A2B3 treatment (Vitamin C / 1 mg / L ascorbic acid, 4.00 g / L activated charcoal) placed in the dark room.

Abstract

Red Chilli is commodity of vegetable that has high economic value, but still has slow productivity. The objective of this study was identify the effect of indigenous microorganism (EM 4) application and compost to increased the growth and yield of Red Chilli Plant (Cappcicum annum L) on Ultisol. Field trial was conducted on Ultisols in Horticulture Experimental Station, BatuahLoajanan, Kutai Kartanegara. The soil was characterized by low fertility status. The amount of organic matter and microbial acivity are very low. This trial was started on January until April 2017 using Split Plot Design with three replications Main plot consisted of two levels treatment i.e. without EM-4 (E0) as control and Effective Mikroorganisms-4 (E). Sub-plot was four rates of organic compost i.e. 0, 10, 20 and 30 tons ha-1 and chili was used as test plant.Results indicated that EM-4 treatment showed a significant effect on fruit yield of chilli. It increased the fruit yield 38 percent compare to control. Compost application significantly increased on fruit yield. The relationship between unfermented compost rate and fruit yield shows a linear regression YE0 = 1.699 + 0.047 X (r = 0.95) and quadratic regression for EM-4 fermented compost YE1 = 1,175 + 0,319 X – 0.007 X2(R2 = 0.603). Optimum compost rate was 23 ton.ha-1.To increased fruit yield of chilli, EM-4 fermented compost should be applied into and it can decreased compost rate application.

Abstract

This research aimed to determine the effect of organic fertilizer to the growth and yield of soybean cultivated on post coal minning soil. The experiment was conducted in Loa Bahu Village, Sungai Kunjang District. The design of the experiment used Completely Randomized Design (CRD) with 8 replications. The treatment is dossage of organic fertilizer (chicken manure bokhasi), consisted of five level. ie: P0 (control, without fertilizer), P1 (17.5 g polybag-1), P2 (35 g polybag-1), P3 (52.5 g polybag-1), and P4 (70 g polybag-1). Data were analyzed using analysis of variance, followed by DMRT at 5% level. The results showed that organic fertilizer was significantly influence the height of the plants at 45 days after planting (DAP), number of seeds per plant, weight of 100 seeds, harvesting time, and total biomass weight. On the other hand it has no significant effect on plant height at 15 DAP, 30 DAP and at harvest time, as well as flowering time, number of branches per plant, number of pods per plant, number of seeds per pod, and weight of seeds per plant. There was a significant different effect of post coal minning soil applied with and without organic fertilizer to the growth and yield of soybean. In addition there was no significant different effect among the organic fertilizer dosage applied. The lowest organic fertilizer dosage of 17,5 g polybag-1 (P1) was considered as the best treatment in this study, since it gave the highest yield per plant. We observed a dominant vegetative growth of soybean, noticed from plant height which was twice higher, and flowering as well as harvesting time which was more than a month longer from general description of soybean variety Anjasmoro. It was suggested that fertility and acidity status (pH 7,43) of the post coal minning soil causing that condition.
