Abstract

Cultivating oranges is one of the main fruit commodities in Bali. Citrus cultivation often experiences problems, one of which is insect pests and plant diseases. Pests that often attack are whitefly. Whiteflies cause damage directly or indirectly. It directly results in stunted plant leaves because the whitefly sucks on the young shoots and leaves. Indirectly, the whitefly has been reported as a vector of various diseases caused by viruses. Based on this, it is necessary to control efforts, one of which is by using biological control of insect pathogenic fungi. The pathogenic fungus found in association with the citrus whitefly is Aschersonia placenta. The insect pathogen A. placenta naturally exists in nature and has potential as a biological control agent, however special handling is required in its utilization. One such treatment is the isolation of the fungus from the field for mass cultivation in the laboratory. Isolation poetry using Potato Sucrose Agar (PSA) was the best, of the four isolation methods performed. The method is detailed as follows: the fungal stroma is rinsed with sterile distilled water, with 70% alcohol, then rinsed again with sterile distilled water before being planted in PSA media.

Abstract

A field trial was conducted to investigate the effect of NPK 15:15:15 at 50:30:30 kg ha-1, Desert-Lion foliar fertilizer (DL) at 25 ml/15 l water, Urea at 50 kg ha- 1, P2O5 and K2O at 30 kg ha-1+Desert-lion foliar fertilizer at 25 ml/15 l water (DPK) and P2O5 and K2O at 30 kg ha-1+ urea at 50 kg ha-1 + Desert-lion foliar fertilizer at 25 ml/15 l water (DPKU) on the performance of okra. A randomized complete block design was used with four replications. Data were collected on growth and yield components. The DPKU, DPK, sole urea and NPK exhibited superior performances in plant height, leaf and branch per plant compare with the sole DL and the control. The DPKU, DPK, NPK and sole urea recorded 40, 39, 38 and 37 fruits per plant respectively, compared to 23 and 35 registered by sole DL and the control respectively. The NPK, DPKU, DPK and sole urea recorded significant total fruit yields of about 7.5 t ha-1, 7.5 t ha-1, 6.5 t ha-1 and 6 t ha-1 respectively, whiles sole DL and the control produced 2.5 t ha-1 and 1.5 t ha-1 yields respectively. The treatment combinations, sole Urea and NPK performed higher than the sole DL. Therefore, for high yield of okra, the DL at 25 ml/15 liters of water should be applied with basal application of 30 kg ha-1 of P2O5 and K2O + urea at 50 kg ha-1 at flowering.

Abstract

Bangkoor Village is one of the rice cultivation centers in Sikka Regency. Intensive agricultural activities supported by the availability of water sources allow farmers to cultivate rice three times a year. In addition, the use of various inputs such as the use of tractors, and the application of fertilizers and pesticides continues to increase crop productivity. On the other hand, the consequences of agricultural activities will certainly have an impact on the physical quality of the soil. This study aims to determine the physical quality of paddy soil in Bangkoor Village, Sikka Regency. The research method used is a survey method and analysis in the laboratory. Soil sampling using the purposive sampling method in three hamlets, namely Hamlet Mamai, Hamlet A, and Hamlet BC. Observational variables observed were soil texture, porosity, and soil water content. Assessment of soil quality using soil physical parameters. The results showed that some of the paddy fields in Bangkoor Village had been damaged or degraded by several factors, namely (1) the weight limiting factor for soil texture classes in the soil in Mamai hamlet, A hamlet, and BC hamlet. (2)The weight limiting factor for soil porosity in the soil BC sub-village.(3) The soil water content is included in the light-moderate limiting factor in all study locations. The effort that needs to be done is the addition of organic matter to paddy fields to be able to improve these limiting factors.

Abstract

Anthracnose caused by the Colletotrichum scovillei is main diseases of cayenne pepper (Capsicum frutescens L.) that affect on plant productivity. The control of plant diseases caused by pathogenic fungi has been widely reported by utilizing of biological agents that applied in biofungicides. Bacillus spp. was reported to have antagonistic abilities against several pathogenic fungus. The purpose of this study was to determine the antagonistic ability of several Bacillus species against Colletotrichum scovillei. The begins was rejuvenatio of the C. scovillei and B. subtillis, B. cereus, B. coagulans, B. thuringiensis that have been identified. The inhibition of Bacillus spp. on the growth and biomass of C. scovillei was tested in vitro, as well as testing the inhibition of Bacillus spp. filtrates on C. scovillei colonies. The inhibitions of Bacillus spp. against the growth of C. Scovillei were ranged from 91.36% to 96.46% and a percentage inhibition on biomass of C. scovillei were ranged from 85.35% to 88.53% compared to the control. Bacillus spp. filtrates was tested at concentrations of 20%-90% were able to inhibit the growth of C. scovillei colonies with a percentage inhibition up to 99.84%. The good quality standard of biological agent must have >70% of inhibition in vitro. The inhibition that occurs by Bacillus spp. on the growth of C. scovillei is likely due to competition for nutrient and space. And other, the possibility of an antagonistic mechanism in the form of the presence of chitinase, which is one of the antifungal metabolite compounds.
