Abstract

Bactrocera dorsalis is a very harmful pest for fruit and vegetable. Chemicalcontrol of these pests has raised another problem. The use of surian leaf extractcan be a good and environmentally friendly alternative control. This study aims to determine the effect of the administration of vegetable pesticides from suren leaf extract in the control of B. dorsalis on red chili. This research had been carried out at Siliwangi University and BBPOPT, Karawang in July to August 2019. This study used a Completely Randomized Design (CRD) with six replications. The concentration of suren leaf extract were : 0%, 0.025%, 0.05%, and 0.1%. The results showed that chili fruit extracts with the highest 0.1% consistently could reduce the number of larvae and the number of fruit attacked. The maincompounds contained in the surian leaf extract include 9,12-Octadecadienoic acid (Z, Z) -, phytol, acetate, phenol, 2-methyl-5- (1,2,2-trimethylcyclopentyl) -, (S) -, Cedren-13-ol, 8-, and 3,7,11,15-Tetramethyl-2-. These compounds were thought to be strong compounds that play a role in suppressing the number of larvae and the number of fruit attacked.

Abstract

Mungbean is one of important sources of vegetable protein in Indonesia. Extensification through the utilization of drylands is very potential to increase mungbean production. The study aimed to find out the response of mungbean given antioxidants of turmeric extract to drought stress. The study was conducted in Kuningan West Java in 2019. The study was designed using a randomized block design with factorial patterns and three replications. The first factor was the concentration of antioxidant of turmeric extract, namely: 0%, 1%, and 1.5%, and the second factor was soil water content namely: field capacity, 75% field capacity, and 50% field capacity. The results showed that the yield of seeds remained high even though mungbean experienced mild stress (75% field capacity) by administering antioxidant of turmeric extract as much as 1% or 1.5%. Likewise, the number of seeds and relative water content of leaves remained high with the same treatment. Meanwhile, plant height, leaf area, and number of pods were increasingly reduced by decreasing the level of soil water content, on the other hand, antioxidants increased the number of filled pods.

Abstract

Research was conducted in Limau Manis, Padang City of West Sumatra. Theexperimental design used was a non-factorial randomized block design. Job’s tears used in this study is a cultivar of beras. The research objective was to determine the effect of various levels of population density on job’s tears growth in sub-optimal area. The density of the population used in this study is that A1 = 62,500 plants / ha (spacing of 40 x 40 cm), A2 = population of 50,000 plants / ha (spacing of 50 x 40 cm), A3 = 40,000 plants / ha (spacing 50 x 50 cm), A4 = 33,333 plants / ha (spacing 50 x 60 cm), A5 = 28,571 plants / ha (spacing 50 x 70 cm), A6 = 25,000 plants / ha (spacing 50 x 80 cm), A7 = 22,222 plants / ha (spacing 50 x 90 cm), and A8 = 20,000 plants / ha (spacing 50 x 100 cm). The results showed that the density of the plant population that was too dense had an effect on the decline in several growth components but showed the highest average ILD value. Whereas treatment with population density that was not too high or by using spacing that was tenuous gave the best effect on the variables of plant height, number of tillers and number of leaves. Further observations are needed to determine the effect of the treatment given on theyield components.

Abstract

Acid mineral soils are soils that have properties such as low pH, low cation exchange capacity, low base saturation, low organic C, high Al saturation and high phosphorus fixation. The technical problem with acid soils is the low level of soil fertility which affects plant productivity. The purpose of this study was to determine the dynamics of the microb population on acid soils. The soil used was two Typic Hapludults from Neglasari Jasinga Village, Bogor and Padasuka Maja Lebak Village with different levels of Al-dd saturation. Soil microb population included total microbes, total sulfate reducing bacteria and total Acidithiobacillus ferrooxidans. Acid soils from Jasinga and Lebak have soil conditions with acidic pH, low organic C content. For acid soils from Jasinga, the highest total of microbes was at a depth of 0-35 cm and the highest total of Acidithiobacillus ferrooxidans was at a depth of 0-35 cm. Whereas for acid soils from Lebak, the highest total of microbes was at a depth of 0-15 cm and the highest total of Acidithiobacillus ferrooxidans was at a depth of 15-40 cm. There was no population of sulfate-reducing bacteria in acid soils from Jasinga and Lebak.

Abstract

Soybean production can be increased through extensification and marginal land becomes inevitable to be used due to the decrease of productive land. Plants grown on marginal soil, especially saline soils, show abnormal growth due to oxidative damages causes yield decrease even death of the plants. The objectives was to study invigoration technique using natural antioxidant and mycorrhizal fungi to increase soybeans tolerance under salinity stress. The research used factorial randomized block design. The first factor was salinity stress (0 and 1 % (w/v) NaCl concentration), the second factor was natural antioxidant (0, 1, 1.5, and 2% mangosteen peel extracts), and the third factor was arbuscular mycorrhizal fungi, 0 and 1g/polybag. The research was replicated three times. The variables were plant height, number of leaves, leave area, chlorophyl content, yield components and yield of soybean. The data was analyzed with Anova and Duncan’s multiple range test at 5% significant level.  The conclusion was that salinity stress inhibited plant growth, yield components and yield of soybean. The application of arbuscular mycorrhizal fungi decreased the negative impact of salinity on vegetative growth, yield components and yield of soybean. The application of 2% mangosteen peel extract gave good effect on vegetative growth, yield components and yield of soybean under salinity stress.
