Abstract

The application of organic fertilizers can improve soil fertility specifically on Inceptisol soils which are quite extensive but have problems with relatively low nitrogen nutrients so that the effort to overcome this is through the addition of organic matter into the soil through organic fertilization or with inorganic fertilizers. The purpose of this study was to determine the effect of the application of goat and urea fertilizer on the chemical properties of inceptisols from Rantau Selatan. This research was carried out at the Agrotechnology Practice Field, Faculty of Science and Technology, Labuhanbatu Rantau Prapat University from February to May 2021. This study used a factorial Randomized Block Design (RAK) with 2 factors, namely factor 1 urea with 4 levels, namely: U0 = 100 kg urea /ha (0 g urea/5 kg weight of oven-dry soil or BTKO), U1= 100 kg urea/ha (0.25 g urea/5 kg BTKO), U2= 200 kg urea/ha (0.50 g urea/ha) 5 kg BTKO), U3 = 300 kg urea/ha (0.75 g urea/5 kg BTKO) and factor 2, the factor of giving goat manure with 3 levels, namely: K0 = 0 tons N/ha (0 goat manure/ 5 kg of oven-dry soil weight), K1 = 10 tons N/ha (25 g Fertilizer, Goat Cage/5 kg BTKO), K2 = 20 tons N/ha (50 g Fertilizer, Goat Cage/5 kg BTKO), K3 = 30 tons N/ha (75 g Fertilizer, Goat Cage/5 kg BTKO). The results of the research application of goat manure increased the N-total dose of Urea: 0.25g and goat manure: 75g on Inceptisol soil while the interaction of urea and goat manure application increased the total N-total with Urea dose: 0.25g and goat manure: 75g) South Coast Inceptisol soil

Abstract

Rice is a major staple food for the Indonesian population, therefore, its productivity must be improved to accomplish the domestic consumption. Efforts to increase rice production in a sustainable manner in the future not only rely exclusively on lowland rice production but also from other genotypes including upland rice. West Sumatra is one of the province in Indonesia that preserves various local upland rice germplasm. The characterization of local upland rice genotypes to drought stress are required in order to support the increase of national rice production. This study aims was to obtain the West Sumatra local upland rice genotypes that are resistant to drought. The drought resistance screening was carried out in three ways, namely: 1) Testing of seed resistance with Polyethylene Glycol (PEG), 2) Testing of root penetration using a wax coating, and 3) Testing of proline content. From the study, two genotypes, namely: Susun Porti and Ladungan which have good resistance to drought.

Abstract

Sawdust is an abundant material in rural areas of Lima Puluh Kota Regency, making its utilization an effective way to prevent it from being wasted. Sawdust also has great potential to enrich soil with essential elements needed by plants. The process of making organic fertilizer typically involves the addition of microorganisms to accelerate the decomposition of organic materials. One of the challenges in producing and developing organic fertilizer is selecting the right decomposer to ensure that the composting process does not take too long and can be quickly applied and utilized by farmers. This study aims to identify the best decomposer capable of breaking down and accelerating the composting process of sawdust waste. The study used a Completely Randomized Design with the following treatments: sawdust:chicken manure (2:1) + bioactivator, sawdust:chicken manure (2:1) + bio tanduria, sawdust:chicken manure (2:1) + m21 dan sawdust:chicken manure (2:1) + Trichoderma sp. Observation parameters: compost maturation time (days), texture, color, moisture and temperature. From all observations of sawdust compost, treatment A2 (sawdust:chicken manure (2:1) + bio tanduria) showed the best results, and the composting time was also relatively short.

Abstract

Sustaining and improving melon production is essential to fulfill the increasing demand for melon fruit in Indonesia. In order to maintain this level of production, it is necessary to utilize insecticides to manage the pests that pose a threat to melon crops. This research aims to assess the impact of insecticide application on the pollination activity of Heterotrigona itama, a vital pollinating insect for melon plants. This research aimed to investigate the effect of Heterotrigona itama activity on melon plants in a greenhouse treated with insecticides. The study was carried out utilizing a survey-based methodology. Data was collected on several aspects of Heterotrigona items' behavior before and after applying insecticides. The research findings demonstrated that using insecticides on melon crops within a controlled environment decreased the frequency of visits from Heterotrigona itama to the melon flowers. Additionally, it was observed that the application of insecticides resulted in the mortality of Heterotrigona itama within the initial six days following the insecticide spraying. On the second day, the maximum number of individuals present was 14. The analysis of Heterotrigona itama honey revealed that the detected levels of pesticide residues were lower than the benchmark dose response (BMR) threshold.

Abstract

Microgreens represent a novel approach to urban farming, characterized by its simplicity, straightforwardness, and cost-effectiveness. This research aims to evaluate the use of coconut water waste as a liquid organic fertilizer (POC) in promoting the growth of green bean microgreens (Vigna radiata). The study was conducted over one week in the Kotapinang District of South Labuhanbatu Regency, utilizing analysis of variance (ANOVA) to assess four treatments with varying doses of coconut water POC: P0 as the control, 10 ml, 20 ml, and 30 ml. The data collected were analyzed using SPSS version 25.00, and the BNT test was applied at the 5% significance level to evaluate the differences between treatments. The results of the observations indicated that at 4 days after planting (DAP), the P3 treatment yielded the greatest plant height, averaging 13.83 cm. Conversely, at 7 DAP, treatment P1 exhibited the highest growth, with an average plant height of 19.66 cm. In terms of leaf width, treatment P1 also performed the best, with an average leaf width of 1.2 cm. These findings suggest that the application of coconut water as POC can significantly enhance the growth of green bean microgreens.

Abstract

The development of cauliflower cultivation (Brassica oleracea var. botrytis L.) on marginal land necessitates implementing appropriate cultivation techniques to enhance plant growth and production. In this context, applying organic fertilizers, such as Kasgot and NPK fertilizers, is anticipated to improve the productivity of cauliflower in Riau Province. This study aims to evaluate the effects of Kasgot and NPK fertilizers on the growth and production of cauliflower cultivated on red-yellow podzolic soil. The research was conducted at the UIR Experimental Garden in Pekanbaru from August to December 2024. A Completely Randomized Design (CRD) Factorial was employed for this study. The first factor examined was the dosage of Kasgot fertilizer (K), which included four treatment levels: no Kasgot fertilizer, and Kasgot fertilizer at 100 g, 200 g, and 300 g per polybag. The second factor examined was the NPK fertilizer (N) dose, which included five treatment levels: no NPK, and NPK fertilizer at 3.75 g, 7.5 g, 11.25 g, and 15 g per polybag. Each experimental unit was replicated three times. The results indicated that the data collected, including plant height, age of flower formation, relative growth rate, flower weight per plant, flower diameter, and root volume, were significantly influenced by the interaction between phosphorus fertilizer and NPK fertilizer. The combination of 300 g of Kasgot fertilizer per polybag and 7.25 g of NPK per polybag proved to be the most effective in enhancing the relative growth rate, flower weight per plant, and flower diameter in cauliflower.

Abstract

Endophytic fungi are organisms that infect healthy plant tissue without causing visible symptoms. This study aimed to determine the presence of endophytic fungi in cocoa plants following the application of boron and sodium hypochlorite. The research was conducted at the Screen House of the Faculty of Agriculture at Hasanuddin University and continued at the Disease Laboratory within the Department of Pest and Plant Disease Science, also at Hasanuddin University, from October 6, 2013, to March 15, 2014. Boron was applied to the plants in three treatments: Treatment A received 1 gram of boron, Treatment B received 0.5 grams of boron, and Treatment C served as the control group with no boron applied. Additionally, the plants were treated with sodium hypochlorite, which was sterilized for 5 minutes before the identification process to characterize the fungi. The results indicated that three genera of endophytic fungi were isolated from the cocoa plant stems following the application of boron: Aspergillus sp., Trichoderma sp., and Colletotrichum sp. Furthermore, one endophytic fungus, Rhizoctonia sp., was isolated from the cocoa stems after applying sodium hypochlorite.

Abstract

Leptocorisa oratorius F. is one of the factors causing the decline in rice production. Appropriate and safe control measures for the environment need to be taken, considering that the use of chemical pesticides can have a negative impact on the environment. The treatment solution that can be used to deal with the stink bug pest (Leptocorisa oratorius F.) is by using plant-based pesticides which are known to be relatively safe because they do not pollute the environment and are easy to obtain. A plant that has the potential to be used as a botanical insectiside is citronella (Cymbopogon nardus L). The research aims to obtain a concentration of citronella leaf extract (Cymbopogon nardus L) that is effective in controlling the stink bug pest (Leptocorisa oratorius F.) on rice plants. The research was carried out at the Plant Pest Laboratory and Greenhouse, Faculty of Agriculture, Riau University, which was carried out for three months from Januari to Maret 2023. The research was carried out experimentally using a completely randomized design (CRD) consisting of five treatments and four replications so that 20 experimental units were obtained with various concentrations, namely 0 g.l-1 water, 25 g.l-1 water, 50 g.l-1 water, 75 g.l-1 water, 100 g.l-1 water. The results showed that the application of the stems and citronella leaves extract concentration of 75 gl-1 water is an effective concentration for controlling L. oratorius because it can cause a mortality of 85% with an initial time of death of 17.75 hours after application and a lethal time of 50 at 61.25 hours after application. The exact concentration of peper elder extract to control 50% of Leptocorisa oratorius is 4.31% or the equivalent of 43.1 g.l-1 water.
