Abstract

Corn (Zea mays L.) is the second staple food after rice in Indonesia. The main problem in corn cultivation is the attack of Spodoptera frugiperda J.E. Smith. The S. frugiperda pest can cause a loss of 73% yield, if the affected plant population reaches 100%. The control using botanical pesticides extracts of forest betel leaf (Piper aduncum L.) is an alternative for controlling S. frugiperda. This study aimed to obtain an effective concentration of forest betel leaf powder extract to control S. frugiperda. The research was carried out at the Plant Pest Laboratory and Experimental Garden, Faculty of Agriculture, Riau University. This study was conducted from February 2020 to April 2020. This study used a completely randomized design (CRD) with five treatments and four replications in order to obtain 20 experimental units. The treatments given were the concentration of forest betel leaf powder extract 0 g.l-1 water, 25 g.l-1 water, 50 g.l-1 water, 75 g.l-1 water and 100 g.l-1 water. The results showed that the concentration of 75 gl-1 water was an effective concentration to control S. frugiperda with an initial time of death of 11.75 hours, lethal time of 50 at 43.25 hours after application, the highest daily mortality on the second day at 52.5% and total mortality is80% in the 5 days after application.

Abstract

Cocoa (Theobroma cacao L.) is a plantation crop that has an important role in the national economy. Conopomorpha cramerella Snellen is a pest that causes a decrease in cocoa production in the field. The recommended control is using botanical insecticides using soursop leaves (Annona muricata L). This study aimed to obtain best concentration of soursop leaf flour extract (A. muricata L) to control the attack of cocoa pod borer (C. cramerella Snellen) in the field. The research was conducted in the garden of residents of Nan Sabaris District, Padang Pariaman Regency, from July to October 2019. The research was carried out experimentally using a completely randomized design (CRD) with 6 treatments and 4 replications. Treatment of the concentration of soursop leaf powder extract given in each experimental unit was 0 gl-1 water, 20 gl-1 water, 40 gl-1 water, 60 gl-1 water, 80 gl-1 water and 100 gl-1 water. The results showed that soursop was able in controlling CPB (C. cramerella) pests at a concentration of 100 gl-1 water which reduced the percentage of affected fruit to 10% with the lowest fruit damage intensity, namely 12.48%, the largest fruit diameter was 18.15 cm, with the smallest larval population of 0.75 tails, and the maximum dry weight of seeds reaching 150.75 g.

Abstract

Garlic (Allium sativum L.) is one of the important commodities in the horticultural sub-sector which is one of the basic needs of the community that must be fulfilled. However, garlic production in Indonesia has not been able to meet the demands of society's needs. For this reason, an additional area of land for garlic development is aimed at the optimal suitability of environmental physical factors. The use of superior varieties is one of the technologies that play a role in increasing the productivity of garlic. This research was conducted in May - August 2020 in Tarusan and Muaro Aie Bayang Utara, Pesisir Selatan Regency, West Sumatra Province with a randomized block design using Lumbu Hijau, Lumbu Kuning and local varieties of Bukik Sileh Solok as treatment. The results showed that the varieties of Lumbu Kuning and Lumbu Hijau were able to adapt well in Muaro Aie with an altitude of 322 masl compared to Tarusan with an altitude of 4 masl. Both varieties gave a fairly good growth response and yield, although only half of the description of these varieties.

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

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.

Abstract

Efforts to intensify oil palm (Elaeis guineensis Jacq.) are needed to increase productivity close to the actual production potential of oil palm crops. The productivity and growth of oil palm is partly controlled by the relationship between the top of the plant (the leaf) and the bottom of the plant (root). This study aims to find out the effect of root pruning and the number of fronds on the growth, production and quality of oil palm products. The research was conducted for 12 months from February 2018 to January 2019 in gardens owned by the community of Petapahan Village, Tapung District of Kampar Regency, Riau. The research was conducted experimentally using split plot design which is grouped based on different plant age (5 years, 10 years and 15 years). The main plot is the pruning of oil palm, Normal, Light, and Heavy fronds. The plot is trimming the roots of oil palm 75%, 50% and 25%. The results showed that root pruning and the number of fronds did not affect the interaction of observational premeters. Pruning the roots independently gives a noticeable influence on the content of mesocarp oil. Self-trimming of the fronds has a real effect on the total increase in oil. Plant life has a noticeable effect on enhancement, total oil, mesocarp oil and free fatty acids.
