Abstract

Aluminum stress is a limiting factor for crop production on acid dry land with a low pH. The objectives of this study were to evaluate aluminum-tolerant upland rice varieties in acid dry land. The study was carried out using a completely randomized block design (RCBD) consisting of 8 varieties, namely IR64, Inpago 7, Dodokan, Dod-Pup1, Situ Bagendit, Situ Bg-Pup1, Batur, Batur-Pup1, and 4 strains, namely 19 (PB5)-2, 20 (PB8)-1, 21 (PB15)-1, and 22 (PB16)-1. The results showed that the Situ Bagendit variety with the Pup-1 locus gave the highest yield per plot compared to other varieties and lines, namely 287.5 g. These results also correlate with the ability of the variety to withstand aluminum stress, with a tolerance value of 3.00 (rather tolerant).

Abstract

The presence of weeds in rubber plantations causes a decrease in productivity so it needs to be controlled. An effective and efficient method on a broad scale in terms of cost and time to control weeds is the chemical method using herbicides. One of the active ingredients of herbicides that can control rubber plantation weeds is paraquat dichloride. The purpose of this study was to determine the effective dose of paraquat dichloride in controlling rubber plantation weeds. This study used a randomized group design (RAK) with 6 treatments and 4 replications. The treatments consisted of herbicide application of paraquat dichloride at a dose of 310.5 g ha-1 (P1); 414 g ha-1 (P2); 496.8 g ha-1 (P3); 621 g ha-1 (P4), mechanical (P5), and control (P6). The results showed that: (1) paracuat dichloride herbicide at a dose of 310.5-621 g ha-1 effectively controlled total weeds and weeds per class; (2) paracuat dichloride herbicide at a dose of 310.5-621 g ha-1 resulted in changes in weed composition at 4-12 MSA; (3) application of paracuat dichloride herbicide at a dose of 310.5-621 g ha-1 did not cause poisoning in rubber plants.

Abstract

OPT problems are still a major obstacle to organic rice cultivation due to limited understanding and control skills. The aim of implementing community service activities is to provide additional skills and insight regarding OPT control technology with local biological agents to solve the problem of organic rice farming in Bumiagung village, Tegineneng, Pesawaran. Technology transfer activities regarding the application of control with local biological agents to solve the problem of pest attacks on organic rice plants were carried out in Bumiagung Village, Tegineneng, Pesawaran which were carried out in June - October 2022 to the Progressive Organic Farmers Community. The stages of the activity are carried out in stages through conducting surveys, providing material, pre-testing, training and mentoring, post-testing, monitoring, and evaluation at the end of the activity. Before the activity begins, a survey is carried out to analyze conditions and problems and analyze the solutions needed for these problems. Farmers need to gain more knowledge and skills in managing pests that attack their land. The controls that are often used are vegetable pesticides and refugia. From the final evaluation results, the analysis shows that farmers realize that control with biological agents is effortless, inexpensive, and synergistic in supporting organic farming.
