Abstract

Rice is a food commodity with economic value as the main staple to maintain national and global food stability. The need for rice is in genotype with population growth, so it is necessary to increase production and productivity. The development of superior varieties requires genetic resources from local rice genotypes from West Sumatra regions, including Marapulai, Silih Baganti, Bujang Marantau, Hitam Manih, Junjuang, Mundam, Papanai and so on. Information on plant performance tests related to growth, agronomic components, and resistance to pests and diseases of local genotypes of lowland rice is still very limited. The experiment aimed to obtain local genotypes of lowland rice that had the appearance and resistance to pests and diseases. The observed growth and yield components were planting height, number of productive tillers, flowering age, ripening age, panicle length, number of seeds per panicle, number of good seeds per panicle, 1000 grain weight, and dry grain weight per ha. Pest and disease resistance variables are; brown planthopper pests, bacterial leaf blight and blast disease. Observational data were analyzed by F test at 5% level with the Least Significant Difference (LSD) at 5%. Analysis using PC software program Statistix ver 8.0. Collected data are observing pest and disease resistance based on assessment standards from the International Rice Research Institute. Based on the growth and agronomic components of the experiment, Maraplai was one of the genotypes that could be used as a superior variety, with the resistance of brown planthopper biotypes 1, 2 and 3 to making them susceptible. Marapulai local genotype has better growth and yield characteristics, as well as resistance to pests and diseases.

Abstract

Apart from being a source of energy, rice is also a source of protein and microelements that are useful for human health, such as B vitamins, iron (Fe), zinc (Zn), anthocyanins, and folic acid. Blast disease caused by the fungus Pyricularia oryzae is an important disease in rice crops worldwide. The aim of the study was to evaluate the resistance of nutritionally specific rice lines to blast disease. The nutritionally specific rice tested were preliminary yield lines and multilocation trials. The pathogens of P. oryzae used were 4 races, namely races 173, 133, 073 and 033. Observations and analysis of resistance to blast disease were carried out based on the IRRI SES method. The results for the preliminary yield trial line showed that the B15068C-MR-1-2-7-KN-2 line showed a resistant response to 4 races of blast pathogen with a disease scale of 1 and as many as 11 special rice lines showed a resistant response or moderately resistant to 4 races, while the multilocation trial lines obtained as many as 3 special rice lines and the variety of Inpari 19 which had a resistant or moderately resistant response to 4 races of P. oryzae. These nutritionally specific rice lines can be used as gene donors for resistance or proposed as varieties that have blast disease resistance. while the multilocation trial lines obtained as many as 3 special rice lines and the variety of Inpari 19 which had a resistant or moderately resistant response to 4 races of P. oryzae. These nutritionally specific rice lines can be used as gene donors for resistance or proposed as varieties that have blast disease resistance. while the multilocation trial lines obtained as many as 3 special rice lines and the variety of Inpari 19 which had a resistant or moderately resistant response to 4 races of P. oryzae.

Abstract

Observation is one of the stages in the selection to obtain the expected rice lines to be tested at the yield and multi-location testing stage as candidates for breeding rice varieties. The research was carried out at the Tamanbogo Lampung Experimental Garden in the 2021 planting season (MT) using an augmented design with five replications of comparison varieties: Inpago 8. Inpago 12, Inpago 13. Situbagendit, and Situpatenggang. As many as 247 promising breeding rice lines were used as materials in this experiment with their respective advantages. Each line was planted with a 0.9 m x 5 m plot size with a spacing of 30 cm x 15 cm. Fertilizer used is 300 kg/ha NPK + 100 kg/ha Urea. Weeding is done twice, precisely at the time before the next fertilization I and II. The observations include 50% flowering age, harvest age, plant height, tiller quantity, dry-milled grain yield, and resistance to biotic and abiotic stresses. The analysis of variance showed that the genotype significantly affected plant height and productive tiller quantities. High heritability and genetic advances in plant height characters indicate that this character is a selection criterion so that selection can be made to increase these characters. The comparison varieties significantly affected the character of plant height and productive tiller quantities. From this activity, 37 breeding lines were obtained with higher yields than the comparison varieties.

Abstract

The objective of the study was to study the effects of spent bleaching earth (SBE) and deoiled bleaching earth (DBE) filler-based NPK fertilizers on the agronomical characteristics of soybean as a model crop. A field experiment was arranged in a single factor of randomized complete block design (RCBD) with four blocks as replications. The treatments were 1) NPK fertilizer with 10% of BC (control), 2) NPK fertilizer with 5% of BC + 5% of SBE, and 3) NPK fertilizer with 5% BC + 5% DBE. The variables observed were the levels of heavy metals in leaf tissue and the agronomic characteristics of soybean plants. The observations were made on several variables of agronomical crop characters. The data were then analyzed with analysis of variance (ANOVA) at 5% levels and continued with the Least Significant Difference (LSD) test if there were differences among treatments. The results confirmed that the SBE and DBE materials could partly replace the filler components in NPK fertilizers, which has been proven to have the same impact on the agronomical characteristics of soybean in the form of leaf area, root volume, number of pods per plant, number of seeds per plant, and seed yield per hectar.

Abstract

The study aims to determine the effectiveness of the application of quail manure and rice straw mulch on glutinous corn (Zea mays var. ceratina) growth and production and the interaction between the effectiveness of quail manure and rice straw mulch. This study used a factorial randomized block design (RBD) consisting of 2 factors with 16 combinations and 32 treatment plots. The first factor was applying quail manure (L) which consisted of 4 levels, 0 kg/plot, 0.85 kg/plot, 1.70 kg/plot, and 2.55 kg/plot. The second factor was the provision of rice straw mulch (Z) which consisted of 4 levels, 0 kg/plot, 1 kg/plot, 2 kg/plot, and 3 kg/plot. Parameters observed were plant height (cm), total leaf (strands), cobs weight per sample (g), cobs weight per plot (g), cob length (cm), and the number of rows (rows). The results showed that the application of quail manure and rice straw mulch affected the parameters of plant height (cm), total leaf (strands), cob weight per sample (g), cob weight per plot (g), cob length (cm) and the number of rows (lines). The interaction of giving quail manure and rice straw mulch did not affect the parameters of plant height (cm), total leaf (strands), cob weight per sample (g), cob weight per plot (g), cob length (cm) and the number of lines (row). The best treatment was found in quail manure and rice straw mulch, 2.55 kg/plot and 3 kg/plot.

Abstract

Drought is the main problem that is often faced in upland rice cultivation in the dry land. Therefore, drought-tolerant rice varieties are needed, but until now, the number is very limited. It is crucial to produce drought-tolerant rice because Indonesia has a relatively sizeable dry land of 148 million ha. This study aimed to obtain a genotype of upland rice that is tolerant to drought with high productivity and can be developed in the dry land. This research was then continued with drought tolerance testing by giving water below field capacity in a greenhouse. This study was in a factorial form using a Split Plot Design, with the main plot of drought stress treatment consisting of tree levels, namely water availability field capacity water, field capacity water, and field capacity water. The sub-plots were four genotypes of upland rice from Deli Serdang North Sumatra consisting of Sialus, Arias, Silayur, Sirabut and one drought-tolerant variety for comparison is Inpago11. The observed variables included plant height, chlorophyll content, number of tillers, number of productive tillers, age of flowering, harvest period, grain weight per clump, and weight of 100 grains. The heaviest drought stress (FCW) caused a significant decrease in plant height, number of tillers per clump, number of productive tillers, and grain weight per clump and extended the flowering and harvesting ages. Based on the tolerance index criteria, it was found that the Silayur genotype was more tolerant to drought stress than the other upland rice genotypes.

Abstract

The low production of eggplant plants in Indonesia is due to the fact that the business of these plants is less intensive and is still traditional without intensive cultivation, especially in the use of fertilizers so that it can support the growth and yield of eggplant plants. Increasing production yields can also be done by means of fertilization using the right dose. The main function of fertilizer is to provide or add nutrients which are sometimes available in small quantities, or even not available at all in the soil. Organic chicken manure and inorganic phosphate fertilizers contain various types of nutrients and substances needed by plants. For this reason, it is necessary to find the appropriate dose used to obtain optimal growth and yield of eggplant plants. Research Objectives To determine the dose of chicken manure and phosphate fertilizer on the growth and yield of eggplant (Solanum malongena L). To determine the effect of chicken manure doses and phosphate fertilizer doses and the best interaction between chicken manure doses and phosphate fertilizer doses on the growth and yield of eggplant (Solanum malongena L). The experimental design used in this study was a factorial randomized block design (RBD) consisting of two treatment factors, namely: Factor I: Dosage of chicken manure (A) consisted of 3 levels, namely: A0= Kontrol, A1= 4 kg/plot (6 ton/ha), A2 = 6 kg/plot (8 ton/ha). Factor II: P0= Kontrol, P1= 4,5 g/plot, P2= 9,0 g/plo, P3= 13,5 g/plot. The results showed that the dosage of chicken manure was significantly different for plant height, number of primary branches, number of sample planting fruit, sample planting production and production per plot. The best dose of chicken manure in this study was A2 (6 kg/plot). Phosphate fertilizer dosage treatment was significantly different for plant height, number of primary branches, number of sample planting fruit, sample crop production and production per plot. The best dose of NPK fertilizer in this study was P3 (13.5 g/plot). The interaction between cow manure and phosphate fertilizer doses was not significantly different on plant height, number of primary branches, number of sample planting fruit, sample crop production and production per plot.

Abstract

Deforestation or functional change from forest to non-forest plays a role in changing ecosystems and species within it. Insects as one of the faunas in it is an interesting aspect to be studied, especially ants. The research was conducted in Nagari Gunung Selasih and Sungai Kambut, Pulau Punjung District, Dharmasraya Regency, West Sumatra from November 2017 to January 2018. This study aims to determine the diversity of ants in the palm oil plantation ecosystem bordering the forest ecosystem. This research takes the form of a survey where the Purposive Random Sampling method was used for points sampling. Hand Collecting, Bait Trap, and Pitfall Trap sampling methods were applied for each plant. Identification of the samples obtained was carried out at the Animal Taxonomy Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. Total ants (Hymenoptera: Formicidae) collected during the study were 3,046 individuals consisting of 5 subfamilies, 15 genera, and 29 species. The most dominant species was Anoplolepis graciliphes, followed by Odontoponera denticulate and Odontomachus simillimus. Based on the results of the study, it can be concluded that the level of abundance and diversity of ant species is not directly affected by the distance from the forest ecosystem, but it is strongly influenced by the composition of environmental factors such as temperature, humidity, light intensity, altitude, and management of existing habitats and vegetation.

Abstract

Okra (Albemoschus esculentus L) is a fruit-shaped vegetable crop and is a potential crop because it has business opportunities. Okra production is still low and has not been able to meet the needs of one of the problems, namely inappropriate fertilization. It is necessary to conduct research that aims to determine the effect of Potassium fertilizer and organic rabbit fertilizer on the growth and yield of okra. The research location is in Sampali Village, Percut Sei Tuan District, DeliSerdang Regency, North Sumatra Province. When the research was carried out in February-May 2021, the materials used were okra seeds, potash fertilizer and rabbit manure. The research method used a factorial Randomized Block Design (RBD) with two treatments and three replications of Potassium (K), namely: K0: without K fertilizer, K1: 5 g/plot, K2: 7.5 g/plot, K3: 15 g/plot while rabbit organic fertilizer (P), namely: P0: without rabbit organic fertilizer, P1: 1 kg/plot, P2: 1.5 kg/plot, P3: 2 kg/plot. The results showed that for observation the number of fruits per plant had no significant effect but gave the best results on Potassium 15 g/plot and organic fertilizer for rabbits P3: 2 kg/plot while Potassium fertilizer had a significant effect on stem diameter and flowering age while organic fertilizer for rabbits had a significant effect on plant height this is because Potassium fertilizer functions to strengthen stems, physiological processes, formation of flowers and fruit. While rabbit organic fertilizer contains nitrogen which plays a role in the vegetative phase for plant growth.

Abstract

The objective of this study was to assess the effect of the type and dose of compost on the growth of oil palm seedlings in pre nursery with coastal sandy soil. The other objective is to know the effect of the type of compost on the growth of oil palm seedlings in pre nursery with coastal sandy soil. Lastly, the study examines the right dose of compost that provides the best growth of oil palm seedlings in pre nursery with coastal sandy soil. The experimental design was set in a factorial completely randomized design (CRD) consisting of two factors from April to June 2020 at the Tridharma Research Station Faculty of Agriculture, INSTIPER. The first factor is the type of compost which consists of 2 levels, Lamtoro compost, and vermicompost. The second factor is the dose of compost consisting of 4 levels: control (without compost), 50 gr compost/polybag, 75 gr compost/polybag, and 100 gr compost/polybag. The research data were analyzed using analysis of variance (α =0,05), and if there was a significant effect, it was continued with the Duncan multiple range test ( α = 0,05). Parameters observed included seedling height, total leaf, leaf width, stem diameter, shoot dry weight, root dry weight, root length, and total roots. The results showed that no combination of types and doses of compost significantly affected the growth of oil palm seedlings in pre-nursery. Using vermicompost can significantly increase oil palm seedlings' leaf area and root dry weight. Using compost at a dose of 50 g/polybag increased seedling height, stem diameter, and root dry weight in pre-nursery of oil palm seedlings.
