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 research aims to determine the effect of different combinations of plant population and organic fertilizer dosages on the growth and yield of the best male F1 variety of purple sticky corn. This experiment used a complete randomized block design consisting of six treatments and repeated four times. The treatments consisted of: A. (66.666 plants/ha with 5 ton/ha); B. (66.666 plants/ha with 10 ton/ha); C (53.333 plants/ha with 5 ton/ha); D (53.333 plants/ha with 10 ton/ha); E (40.000 plants/ha with 5 ton/ha); F (40.000 plants/ha with 10 ton/ha). The observed plant responses consisted of: plant height, leaf area, plant dry weight, weight of cobs with husk per plant, weight of cobs without husk per plant, cob length, and cob diameter. The results of this study showed that different combinations of plant population and organic fertilizer dosages had an effect on the plant height, plant height, leaf area at, plant dry weight, weight of cobs with husk per plant, weight of cobs without husk per plant, cob length, and cob diameter of male F1 Jantan variety of purple sticky corn. The combination of 40,000 plants/ha plant population with 5 tons/ha of organic fertilizer gave the best yield for male F1 Jantan variety of Pulut Ungu corn 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.
