Abstract

Improper processing of rice field systems and lack of organic matter in the soil to meet the nutrient needs of rice plants resulted in low rice production. Increased production of rice plants can be overcome by giving compost of palm oil empty fruit bunches (TKKS) with the system of rice intensifications (SRI) method, because the organic matter contained in the compost can improve the physical properties of the soil. This study aims to obtain the best dose of empty fruit bunch (EFB) compost and to see its effect on the production of lowland rice (Oryza sativa L.) by using the modified SRI method. The research was conducted from January-April 2019 at the UPT Experimental Garden, Faperta, Riau University. This study applied a completely randomized design (CRD) consisting of 5 treatment levels. They are 0 gr.polybag-1, 50 gr.polybag-1, 75gr.polybag-1, 100 gr.polybag-1 and 125 gr.polybag-1. The results showed that giving empty fruit bunch (EFB) compost with the SRI method gave an effect on productive tillers, pithy grain per panicle and grain weight, but did not affect panicle exit age, harvest age, percentage of pithy grain per panicle and 1000 grain weight of pithy grain. The best treatment dose was found at a dose of 20 ton.ha-1 because it could increase several components of lowland rice production of the Batang Piaman variety.

This research was conducted in Sona Village with an altitude of 18 meters above sea level Labuhanbatu Regency from December 2019 to March 2020. The material used was tomato seeds, husk charcoal, solid water. The equipment used was a 35x40 polybag, cutter blade, analytical balance, ruler, scissors, mortar, measuring flask, bucket, calipers, neat rope, hoe. The research will be conducted with a factorial group design. The first factor is the provision of Solid namely S0: Without Solid (Control), S1: 0.50 kg / polybag, S2: 0.70 kg / polybag S3: 1kg / polybag. The second factor is the administration of rice husk charcoal P0: Without Husk Charcoal (Control), P1: 0.2 kg/polybag, P2: 0.4 kg/polybag. The number of treatment combinations is 12 combinations. The research results indicate that the provision of Solid and Rice Husk Charcoal Against Tomato Plant Production (Solanum Lycopersicum L) has no significant effect on Stem Diameter (cm), Total Number of Fruits per Plant (g), Total Weight of Fruits per Plant (g). However, the treatment interaction of 1 kg/polybag of Solid and 0.2 kg/polybag of Rice Husk Charcoal can increase Stem diameter (cm), Total Number of Fruits per Plant (g), Total Weight of Fruits per Plant (g).

Abstract

The rhizosphere is an excellent habitat for microbial growth because plant roots provide a variety of organic materials that generally stimulate microbial growth. This study aimed to explore and determine the character of fungi from oil palm rhizosphere (Elaeis guneensis Jacq) on smallholder plantations in Kuantan Singingi Regency. This research was conducted at the Islamic University of Kuantan Singingi. The method used was an experimental method carried out in two stages. The first stage was a random sampling survey. The sample was then taken to the Basic Laboratory of the Faculty of Agriculture, Kuantan Singingi Islamic University for analysis. They are Singingi Hilir District, Kuantan Mudik District, Kuantan Tengah District, Benai District, Pangean District and Sintajo Raya District. The most isolates were found in Singingi Hilir sub-district, the plant age was 2 years and the fertile soil was blackish brown. The least number of isolates was found at the age of 10 years, even though the soil was fertile. The age of the plant affected the microbial activity in the rhizosphere. The older the plant the microbial activity decreased. Therefore, it caused the number of isolates found to be small. Characteristics of isolates isolated at a younger plant age were more varied in color.

Abstract

The development of technology in agriculture is currently speedy, with innovations that can increase the production and quality of agricultural products. Supporting the hydroponic cultivation system's success is by applying porous and well-aerated media and the availability of sufficient nutrients for plant growth and plant production. The availability of Rockwool is difficult to obtain in the 50 Kota Regency. It needs to utilize local potential as a planting medium alternative, such as using bricks and husk charcoal. The research was conducted in a completely randomized design with three replications. The treatments tested for the composition of the growing media using the Drip flow technique (DFT) system included: Rockwool, Husk Charcoal (50%) + Bricks (50%), Husk Charcoal (25%) + Bricks (75%). Based on the results and discussion of the analysis previously described, the conclusions obtained from the research that has been carried out are as follows: Treatment of the use of various types of growing media on the observation of growth and production of hydroponic Pakcoy plants gives significantly different results on the observation variables of leaf length, leaf width, and the number of leaves and plant total wet weight.

Abstract

The decline in production of cabbage in Indonesia is due to the lack of intensive and traditional cultivation of this plant, ie without the use of spacing and frequency that is not appropriate, resulting in a seizure of nutrients from the soil by plants and organ cover of the cabbage plant itself which inhibits the photosynthesis process. So this research was conducted to know the effect of effective spacing that can increase the growth and production of cabbage plants. This study used a single factor randomized block design consisting of 4 levels of treatment, namely 1) Without Planting Distance; 2) Planting distance 35 cm x 35 cm; 3) Distance to plant 45 cm x 45 cm; and 4) Planting distance 55 cm x 55 cm. Each treatment was repeated 3 times to obtain 12 experimental units. The plant spacing factor on cabbage had a significant effect on the observation of plant height, the number of leaves, and leaf length. While the results of observations on the fresh weight of cabbage buds did not have a significant effect on the spacing treatment. The planting distance at 25cm x 55cm gave the best effect on the growth and production of cabbage (Brassica oleraceae L.).

Abstract

Due to the extreme weather that hit throughout the year resulted in the threat of rice plants falling down. It was known that the fall of rice plants was a limiting factor for obtaining high yields and quality of grain. Therefore, it was considered important to evaluate the resistance to fall in the general methods of planting rice in the area. Those were transplanting planting (TP) and direct seed planting (TBL). Based on this objective, we identified the morphophysiology of rice stems in the laying factor of 2 planting methods commonly used by farming communities, namely transplanting planting and direct seed planting. Identification was carried out by observing the morphology and physiology of the rice stalks, the laying index and the level of fall of rice plants in each planting method (TP and TBL). The result of the research was that the direct seed planting method (TBL) tends to show morphophysiological identification results that were not resistant to falling compared to the transplanting method (TP). The laying rate shown by TBL was accounting for 75.5% while transplanting (TP) was only 5.7% of the experimental unit area. Significant differences were observed in plant height, stem length, center of gravity height, laying index, laying level, stem internode length, stem internode width, bending moment and bending stress of the stem. In the experiment, it was also found that the grain was damaged due to the fall of the rice plant when the rice fields were flooded. Therefore, it is important to carry out agronomic management as part of sustainable mitigation of the risk of falling rice plants to support national food security

Abstract

The use of chemical pesticides is still considered for rice farmers to be one of the most effective ways for pest control. The chemical content in pesticides is toxic and causes an increased risk for farmers and the environment if their use is not under applicable regulations. The limited knowledge of farmers about the application of Integrated Pest Management (IPM) and lack of discipline in the use of pesticides has triggered environmental damage, especially the lowland rice ecosystem and human health. This study aims to determine the use of pesticides by rice farmers in Siak Regency in controlling rice pests. The method used is a purposive sampling interview method using a questionnaire. The results showed that rice farmers had not implemented a pest control system based on the IPM principle, which did not pay attention to the control threshold as a basis for pesticide use. Farmers are satisfied with the effectiveness of chemical pesticides in pest control, so they continue to use them in rice farming. The lack of Farmers' knowledge about IPM and its application can trigger farmers to increase the dosage and frequency of spraying if the chemical pesticides used are not able to control the pest.

Abstract

Land evaluation is the process of comparing a series of data on land, vegetation and climate with specific use requirements. The goal to be achieved is to determine land use options as a bridge between physical, biological and technological components with economic goals to be achieved in a particular form of land use. Agroforestry is an integrated land use system, which has social and ecological aspects, implemented by combining trees with agricultural crops and / or livestock (animals), either jointly or in rotation. This study aims to identify land characteristics, evaluate the level of land suitability and how to develop a combination pattern of agroforestry plants based on Liberika Coffee that is right for the sake of improving the economy of the community in Kedabu Rapat Village. The method used is survey method and soil sampling by transect line at 1 kilometer intervals proportionally. The data analysis performed was scoring and matching between land characteristics and quality data with plant growth requirements using ArcGIS 10.2 software. The results showed that the annual average rainfall was 1,200-2,400 mm / year, temperatures were between 25 ° C - 32 ° C, flat topography with a classification of slope (<3%), soil types were Organosols and Gleihumus, flood hazard from none to moderate and the danger level of landslides and erosion is very light or not prone. The land suitability level for agroforestry based on Liberika Coffee with shade in the form of Coconut, Areca nut and Geronggang plants is very suitable (S1) covering an area of ​​± 848.64 ha (34.78%), the appropriate category (S2) covering an area of ​​± 584.54 ha (23, 96%), the category according to marginal (S3) is ± 521.78 ha (21.38%), and the unsuitable category (N) is ± 380.42 ha (15.59%) while the settlement area is ± 104.61 ha (4.29%). The combination pattern of agroforestry plants based on Liberika Coffee with shade plants of Coconut, Pinang and Geronggang in Kedabu Rapat Village is combination pattern 1 (border tree planting / trees along border) and combination pattern 2 (alley cropping) where Liberika Coffee plants are 2.5 x spacing. 2.5 m, Coconut spacing 10 x 10 m, Pinang spacing 2.5 x 2.5 m and Geronggang spacing 5 x 5 m.
