Abstract

The physical characteristics of ultisols due to the provision of biochar made from palm oil plant residue aims to determine the effect of giving various biochar made from oil palm plant residues on the physical properties of Ultisols. The research design used completely randomized design, consisting of 5 treatments, namely K = without giving biochar, BB = oil palm stem biochar, BP = oil palm frond biochar, BT = oil palm empty bunches biochar and BK = combination of biochar ingredients. Each treatment was repeated 4 times, so that the number of experimental units became 20 units. The parameters observed included soil density, soil porosity, soil texture, soil permeability and available water. The results showed that giving biochar significantly decreased the bulk weight and significantly increased the soil porosity of Ultisols.Key words : biochar, oil palm wastes, physical properties of soil and ultisol

Abstract

The use of organic matter in agricultural production is important in increasing crop production, especially in Ultisols. This study aimed to study the interaction between vermicompost and biochar on the growth and yield of soybean (Glycine max L.) in Ultisols. The research was carried out in the experimental station of the Faculty of Agriculture, Riau University, Bina Widya Tampan campus, Pekanbaru from July - September 2018. The research used factorial design form in a completely randomized design. The first factor is vermicompost which consists of 4 levels (doses of 0, 25, 50 and 75 g of polybag-1) while the second factor is biochar consisting of 4 levels (doses of 0, 25, 50 and 75 g of polybag-1) for each combination repeated 4 times. The parameters observed were the number of effective roots, proportion of effective nodules, plant height, number of primary branches, age of plants, age of harvest, proportion of well-fused pods, number of seeds, seed weight and weight of 100 seeds. The results showed that the interaction of vermicompost at a dose of 25 g.polybag-1 following a dose of 50 g.polybag-1 biochar increased the number of effective root nodules, the proportion of effective root nodules, the number of primary branches, the proportion of pithy pods, and accelerated plant age and soybean plant age compared without treatment but not significantly compared to other combinations.Key words : Soybean, vermicompost, biochar

Abstract

It is estimated that around 95 percent of national rice production is supplied from paddy fields, so the paddy fields is very strategic in national food securities. Therefore, the potential carrying capacity and productivity of rice fields must be maintained and developed. But on the contrary the productivity of paddy fields in Sub Das Tampo, Lintau Buo Utara, Tanah Datar District, West Sumatra, there is an indication of a decrease in paddy productivity in the last 10 years (Agita and Ayendra 2018). Decreased paddy productivity is indicated as a result of 1.) Drainage or nutrient deficit due to harvest carried out more than what is given through fertilization or addition of nutrients from irrigation water, 2). Excess or lack of certain nutrients due to unbalanced fertilization, 3). Decreased of soil organic content in the land and 4). Decrease in the quality of rice field management, especially: a). the use of inorganic fertilizers which causes low organic matter content and soil texture becomes porous quench, so it is less able to hold water, b). use of rotary plow in tillage for a long time which causes the processing layer and the depth of the root zone to become shallower ( into 10-15 cm), c). less intense of crop maintenance. This research was carried out by creating of soil tillage from 10-15 cm to 20-25 cm using a plow and increasing of organic matter by adding manure of 50 tons / ha (5% soil tillage zone ) to the rice fields in the Farmers Group of Tanjung Mutiara in Tampo Irrigation System, Nagari Lubuk Jantan , Kecamatan Lintau Buo Utara. The results of the study showed an increase in land productivity from an average of 3.2 tons / ha to 4.6 tons / ha and increase farmers' income by Rp 1.200.000 / ha.Key words : land creation, soil tillage, productivity

Abstract

The endophytic bacteria are bacteria whose life cycle is partially or completely associated in the host plant tissue in various kinds of relationships (symbiosis) that it undergoes. The potential of endophytic bacteria as microbial resources is widely used as a biological control for plants, including as the producer of phytohormones and the agent of biocontrol and biofertilizer. This study aims to test selected endophyte bacterial isolates from chili as a biofertilizer to meet the nutrient requirements that are useful during the vegetative growth period of red chili in Ultisols. The study used a completely randomized design with 4 treatments and 3 replications, namely A = fertilizer N  recommendation; B = Azospirillum sp AK+ Fertilizer N recommendation; C = Azospirillum sp BT+ Fertilizer N recommendation; D = Azospirillum sp DN+ fertilizer N recommendation. Azospirillum sp AK and Azospirillum sp DN isolates gave better vegetative growth than those of Azospirillum sp BT isolates with average dry weight, respectively, 19.49 g and 18.93 g and with a height of 29.67 cm and 29.60cm. The superiority of the 2 isolates was also shown in the observation of the number of leaves 30.39 and 22.50 and the number of branches 6.45 and 6.28 respectively for Azospirillum sp AK and Azospirillum sp DN isolates.Key words : Endophytic bacteria, red chili, Ultisols
