Abstract

Indonesia is facing soybean shortage and the low productivity of soybean production from decreasing acreage. Saturated soil culture (SSC) could be one of the solutions for marginal land with drainage problem. Saturated soil culture is cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. Farmers can use on-farm inputs that are normally available at the production site. An organic farming system may be able to ensure local and regional food security through continuous production. The study was conducted at Cikarawang Experimental Station of Bogor Agricultural University, Indonesia, from December 2009 to February 2011. The objective of the research was to determine the influence of organic fertilizer application on the productivity of two varieties of soybean, “Anjasmoro” and “Wilis”,    in organic saturated soil culture conducted in two cropping seasons. Prior to the experiment all plots were applied with 2 ton.ha-1 of dolomite, 2 ton.ha-1 of rice hull ash, and 10 ton.ha-1 of chicken manure. The experiment of the first season used split plot design with six replications. The main-plot was organic fertilizer that consisted of chicken manure only (20 ton.ha-1), chicken manure (10 t.ha-1) + Centrosema pubescens (4.2 t.ha-1), chicken manure (10 ton.ha-1) + Tithonia diversifolia (4.2 t.ha-1). The sub-plot was soybean varieties “Anjasmoro” and “Wilis”. The soybean productivity was not affected by the application of organic fertilizers. “Willis” productivity (1.98 t.ha-1) was higher than “Anjasmoro” (1.80 t.ha-1). The experiment of second season used split-split plot design with three replications. The main-plot consisted of 50 and 100% fertilizer rate of the first cropping season; the sub-plot was the same types of organic fertilizer with soybean varieties as sub-sub-plot. Rate of fertilizer, types of organic fertilizer and soybean variety did not affect productivity. Application of 50 and 100% rate of fertilizer in the second season produced 2.41 and 2.55 t.ha-1 of dry seeds, respectively. Soybean plants treated with chicken manure, green manure from C. pubescens and T. diversifolia produced 2.45, 2.50 and 2.49 t.ha-1 of dry seeds, respectively. “Anjasmoro” and “Wilis” produced 2.50 and 2.45 t.ha-1 of dry seeds, respectively. Productivity in the second season was 26.26-36.61% higher than those of the first cropping season.

Abstract

Vetiver is widespread in saline areas. Only a few studies have reported that they are sufficiently tolerant of salt. The primary mechanism of salt tolerance in vetiver is still not known with certainty. This study aims to determine salinity's effect on early growth of vetiver (Vetiveria zizanioides L.) seedlings. This research was conducted in a greenhouse, Faculty of Agriculture, Universitas Sumatera Utara, Medan. This study used a non-factorial randomized block design (RBD), namely the salinity stress (S) which consisted of 3 levels: EC salinity levels of 0 (distilled water), 4 dsm-1 and 8 dsm-1. The salinity stress treatment showed a significant effect of reducing the growth parameters of plant height, leaf area, chlorophyll a and chlorophyll b. Salinity stress treatment gave significantly better effect in conditions without salinity stress.

Abstract

Information Technology and Communication played a important role in the execution of tasks by the Agricultural Extension and Research Agency (BPP). BPP Air Sijorman, located in Asahan Regency, was previously without a website. A community service initiative was undertaken to design a website for BPP Air Sijorman, serving as a platform for agricultural extension and the dissemination of information. The process commenced with socialization and the identification of system needs, followed by website design, implementation, and user training.  The website was conceptualized using CorelDRAW and physically designed by aligning the graphics with the source code on the website. The implemented system resulted in the creation of the BPP Air Sijorman website, which was accessible via both desktop and mobile devices at http://bpp-airjoman.website/beranda.html. The website offered information on farming guidelines, the latest news, agricultural policies, and the BPP profile, accessible through various menus. The response from both BPP and farmers to the BPP Air Sijorman website was highly positive. On average, participants in the training sessions demonstrated the ability to operationalize and effectively use the website. Participants also expressed satisfaction with the website's visually appealing design, user-friendly interface, informative content, simplicity, and easily understandable instructions. This positive feedback underscored the effectiveness of the implemented website, making it a valuable tool for agricultural extension and information dissemination.
