Abstract

Through the use of low dosages of chemical fertilizers and effective nutrient-corn genotypes that respond to bio-fertilizer type assignments, this study intends to produce rather steady outcomes over the course of several growing seasons. Field tests for this study have been conducted at the ATP Ministry of Research and Technology in South Sumatra. The experiment was run across two growing seasons: the dry season (May through September 2011) and the rainy season (January–April 2012). The equal split-split plot design is used for the study's two growing seasons. The central conflict concerns the application of chemical fertilizer at the following rates: P1: 50% standard dose of ATP (200 kg urea, 50 kg SP36, and 25 kg KCl ha-1), and P2: 25% standard dose of ATP (100 kg urea, 25 kg SP36, and 12,5 kg KCl ha-1). Treatment of several biological fertilizer subplots: H0: no biological fertilizer (control); H1: mycorrhiza; H2: bacterial phosphate solvent. The treatment of children plot uses a variety of corn strains with effective nutrient selection outcomes, including strains B41 (G1), L164 (G2), S219 (G3), and variations BISI 816, as the genotype comparison (G4). Three times each was used for each combination of treatments. The results of the two investigations indicate that strain B41 can produce adaptive growth based on the growing season, is more resilient to drought stress, and may be able to produce more at lower doses of chemical fertilizer while being comparatively stable. A combination of chemical fertilizer at the 50% standard dose of ATP and mycorrhizal fertilizer, along with strain B41, has the best impact on the growth and yield of maize on marginal dryland. Mycorrhizae fertilizer at various levels of low doses of chemical fertilizer can increase the growth and yield of maize in two different cropping seasons. All of the examined maize lines generally showed the ability of the bacteria connected to mycorrhizal and phosphate solvents to enhance nutrient absorption

Abstract

Non-cultivated local rice is known to have high resistance to various environmental stresses. This resistance is inseparable from the role of symbiotic and non-symbiotic rhizosphere bacteria that live in the root rhizosphere. This study aims to isolate and study the potential of rhizobacteria that live around the roots of non-cultivated local rice plants. This research is exploratory research to obtain rhizobacterial isolates that can stimulate plant growth and development and can be applied to cultivated rice plants. Soil samples were taken from Mimi Baru Village, Jagebob District. Sampling was carried out aseptically. Isolation was carried out using the multilevel dilution method. Isolates grown in NA media were then subcultured to obtain pure isolates. The isolates obtained were then characterized morphologically according to Bergey's Manual of Determinative Bacteriology and characterized microscopically. Based on the results of this study it can be concluded that there were 12 bacterial isolates in the local rice "Cempo Laut" which were suspected to be Bacillus and Pseudomonas. The results of this study need to be tested further to determine the effect on plant growth and development.

Abstract

The study's full title was "The Effect of Application Intervals of Different Types of Insecticides in Controlling Fruit Fly (Bactrocera sp.) Pests on Production of Curly Red Chili (Capsicum annum L.)." From July 2021 to October 2021, it was conducted in the dormitory area of the Riau Islamic University. The goal of this study was to ascertain how different vegetable insecticide kinds interacted with treatment intervals to control fruit fly pests and curly red chili plant production. This study employed a two-factor, entirely randomized design. The first factor was a combination of four different doses of pesticides, including isoprocarb 2 g/l, betel leaf extract 100 cc/l, neem leaf extract 100 cc/l, and lime leaf extract 100 cc/l. The application time interval, which has four levels—3 days, 6 days, 9 days, and 12 days—is the second element. 48 experimental units were created by combining 16 treatment combinations, each of which had three replications. There were 192 plants total because there were 4 plants per experimental unit and 2 plants were used as samples. The data is statistically analyzed before being subjected to the BNJ test. The outcomes demonstrated that not all parameters were affected by interactions and combinations of application intervals and different insecticide types, including the percentage of flowers to fruit, age at first harvest, fruit weight per plant, fruit weight per fruit, percentage of fruit flies attacked, other types of pests that attack, and age of disease across all treatments.

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.
