Abstract

Potato (Solanum tuberosum L.) has been classified as major source of carbohydrate along with rice, wheat, and corn. As for other crops, potato’s growth and yield are always subject to weed interference. An experiment has been conducted to study the effect of indigenous rhizobacteria to promote the growth and yield of potato var. Cingkariang and weed population at Nagari Pakan Sinayan, Agam District, the Province of West Sumatra. The experiment used a completely randomized design with seven treatments and three replications. The treatments was rhizobacteria indigenous to potato farm at Nagari Pakan Sinayan i.e SWL2.2, Ag2L2S3.3, Ag2L2S4.2, Ag3L3S3.1, Ag3L3S5.1, Ag4S5.2, and one group of without the isolate. Data were analysed with analysis of variance and mean separation following DNMRT at 5%. Results demonstrated that indigenous rhizobacteria promoted plant height, number of branches, and the weight of potato tubers. The rhizobacteria also resulted in changes in weed population. Ten weed species were found prior to the experiment as follows: Ageratum conyzoides L.,  Alternanthera philoxeroides (Mart.) Griseb., Andrographis paniculata (Burm.f) Nees, Bidens pilosa L., Cyperus rotundus L., Crassocephalum crepidioides (Benth.) S. Moore, Eleusine indica L., Echinochola colona (L.) Link, Galinsoga quadriradiata Ruiz & Pav., dan Paspalum commersonii Lamk. However, three new weed species emerged during the experiment. They are Amaranthus spinosus L., Portulaca oleracea L., and Paspalum conjugatum P.J.Bergius indicating changes in weed population.

Abstract

Aphelenchoides besseyi is one of the most important parasitic nematodes in rice plants, capable of dormancy in rice seeds. This study aims to determine the effects of soaking rice seeds in water and pesticides (carbosulfan, benomyl, and imidacloprid) on the mortality of A. besseyi, seed viability, and symptoms in rice seedlings. This study specifically used rice seeds infected with A. besseyi. Cold water treatment (cwt) at 5-10ËšC for 24 hours followed by hot water treatment (hwt) at 52ËšC for 10 minutes caused 51.17% A. besseyi mortality yet reduced the seed viability. Soaking the seed in the water at 25-30ËšC for 24 hours followed by hwt at 57ËšC for 10 minutes and hwt at 52ËšC for 10 minutes could cause 48.67%, 39.18% and 33.05% nematode mortality, respectively. Low nematode mortality in all treatments (less than 60%) showed symptoms of A. besseyi infection in rice seedlings 21 days after planting. Seed dressing with imidacloprid 5WP (2% by seed weight) caused 47.25% A. besseyi mortality, whereas benomyl 50WP (0.2% by seed weight) and carbosulfan 25ST (2% by seed weight) caused only 27.61% and 11.34%. Based on two parameters (nematode mortality and seed viability), the most effective treatments were soaking the rice seeds in the water at 25-30ËšC for 24 hours and seed dressing with imidacloprid.

Abstract

Rice is one of the priority food crop in Indonesia. The main problem faced by rice cultivation is the attack of brown planthopper (Nilaparvata lugens Stall.), this pest is one of the most important pest in rice cultivation, because it can cause a production decrease up to 100% by causing hopperburn symptoms and becoma a desease vector. Botanical pesticide of spiked pepper (Piper aduncum L.) can be the safe alternative to controling brown planthopper. This research aims to obtain effective concentration to controling brown planthopper. The research was conducted at The Plant Pest Laboratory Faculty of Agriculture and Organic Chemistry and Natural Materials Laboratory Faculty of Engineering, Riau University, from November 2020 to Januari 2021, using completely randomized design (CRD) consist of 6 treatments 4 replications. The treatment application consisted of concentrations of 0%, 0.20%, 0.40%, 0.60%, 0.80%, and 100% spiked pepper leaf methanol solvent extract. The result showed that different concentration significantly affected to the death of brown planthopper. Concentrations starting from 0.20% has good performance in killing pest, but the effective concentration to control brown planthoppers is 0.60% concentration of spiked pepper leaf methanol extract, with a total mortality of 82.50%, initial time of death 3.25 hours, and 50% time of death at 10 hours after application.

Abstract

Farmers in specific region can play a crucial role in preventing the extinction of rare rice varieties by maintaining their commitment to local rice production. This not only contributes to the economic stability of the community but also necessitates exploration efforts to identify and gather specific plant species at risk of extinction. This study employs a descriptive research design to identify, gather, and compare the relationships between local rice genotypes in the Kuantan Singingi regency. The survey method utilizes a planned sample of rice seeds.The exploration process involves observing geographic coordinate locations, collecting local rice seeds, and examining grain and rice morphology based on Bioversity International, IRRI, and WARDA standards from 2007. The Kuantan River, with an altitude ranging from 28.95 to 61.56 meters above sea level, is prone to frequent flooding. A morphological study of grains reveals that, out of 26 local rice genotypes, one pair exhibits the highest similarity rate of 71% when compared to more diverse types. Notably, the white sironda rice from Pulau Madina village in Kuantan Hilir district and pandan wangi rice from Pauh Angit village in Pangean district are identified as the most identical genotypes. By identifying and preserving unique and highly-potential indigenous rice genotypes, this research significantly contributes to the enhancement of food stability, rural economy, and genetic resilience of rice plasma in Indonesia.

Abstract

Fruit flies ( Bactrocera spp.) represent a group of Plant Pests that can inflict both qualitative and quantitative losses. The utilization of chemical pesticides and the scarcity of Methyl Eugenol continue to pose significant challenges in agriculture. The abundant availability of Melada plants presents an opportunity for the development of an economically viable and environmentally friendly biological attractant. Encapsulation technology based on Maltodextrin and Gum Arabic (MD-GA) formulated with powdered simplicia of Melada leaves F1(02:10), F2(05:10), F3(10:10), and F4(12:10) is employed to enhance the slow-release resistance of volatile compounds. The surface oil content of the four formulations ranges from 0.3% to 9.6%. The encapsulation efficiency value for the four formulations ranges from 70% to 85%. The loading capacity value ranges from 0.7% to 1.3%. The yield value of microcapsule characteristics ranges from 63% to 82%. Morphological analysis reveals a decrease in the number of particles along with the combination of treatment formulations. The size of the microcapsules for the four formulations falls within the range of 201.2 µm–252.6 µm. The effectiveness of the resulting attractant can lure 19-185 fruit flies. The diversity of the fruit fly pest population obtained includes the Bactrocera umbrosa and Bactrocera melastomatos species. The total value of the best formulation for the four treatments ranged from 0.3% to 0.5%. The optimization of the best biological attractant application with high development potential lies in the encapsulation formulations F3 and F4.
