The objectives of this study were to know drought susceptible and resistant varieties of soybean-based on the average value of drought susceptibility index and correlation of yield and yield components traits under drought stress condition. This study was conducted using an experimental method and was laid out using Factorial Completely Randomized Design (CRD), two factors with three replicates of each experimental unit. Factor 1 soybean variety consists of 7 genotypes: Lawit, Sibayak, Kaba, Pangrango, Seulawah, Nanti, and Burangrang, and factor 2 drought stress condition: no drought stress (reasonable condition), drought stress during the vegetative phase, drought stress during the generative phase, and drought stress during vegetative and generative phases. Yield component traits observed were the number of pod per plant, number of empty pod per plant, number of filled pod per plant, number of seeds per plant, the weight of 100 dry seeds, and seed weight per plant. Based on the results of the study, it can be concluded that: 1). Variety of Sibayak and Nanti, were classified as resistance to drought stress either during the vegetative phase, generative phase, or continuous drought. 2). The highly significant positive correlation of among yield and yield components of soybean under drought stress were: seed weight per plant - number of pods, seed weight per plant - number of filled pods, and seed weight per plant - number of seed per plant, while highly significant negative correlation occurred in the character of flowering date - 100 seed weight.
The purpose of this activity is to increase the knowledge and skills of farmer groups to understand increasing the productivity of dry land by implementing corn-peanut intercropping cultivation. The program that has been implemented is the application of science and technology, with the stages of activities, namely: 1) dissemination activities on optimizing dry land with the corn-peanut overlapping technique, selecting peanut corn varieties that are adaptive to dry land and shade, as well as plant cultivation techniques on land dry. This activity was carried out with a system of lectures and discussions between the Extension Team and the Farmers' Group, and 2) a demonstration plot program involving farmers from the preparation/planning of the program to the implementation of the demonstration plots. Farmers directly participate in planting, maintaining, comparing, and evaluating whether the implemented program will provide benefits or not. The results of the activity showed that the farmers participating in the extension were very responsive to the corn-peanut intercropping dissemination activity. This is reflected in the enthusiasm of the participants in asking questions and the discussions between the participants or extension workers. In addition, participants were also active in participating in every stage of activities such as selecting good seeds, making demonstration plots, planting, stockpiling, weeding, pest and disease control, and harvesting activities. There is a process of technological transformation of corn-peanut intercropping on the dry land of Mbawi Village, Dompu District, Dompu Regency, with the hope that farmers will be able to utilize the dry land by intercropping. Intercropping can increase land productivity with a Land Equivalent Ratio (LER) value of 1.3 compared to corn monoculture and 3.1 compared to peanut monoculture
This extension activity aimed to help Farmer Group partner of the "Sumber Hidup" in Sigerongan Village to increased the productivity of narrow land through the application of intercropping technology between okra crop and peanut genotypes. The program that implemented were the application of science and technology with stages of activities, namely: 1) dissemination activities "optimization of productivity of narrow land through the application of intercropping okra and peanuts and the application of technology to increased production of okra and peanut”. This activity was carried out with a lecture and discussion system between the Extension Team and the Farmer Group, and 2) plot demonstration program. Farmers directly participated in planing, planting, crop maintaining, comparing and evaluating whether the implemented program will benefit or not. The results of the activity showed that the farmers participating in the extension were very responsive to the dissemination of intercropping okra-peanut. This was reflected in the participants' enthusiasm in asking questions and having discussions between participants with Team. In addition, participants were also active in participating in each stage of activities such as selecting seed quality, making demonstration plots, planting, growing, weeding, controlling pests and diseases, and harvesting activities. The transformation process of the okra-peanut intercropping technology in the narrow land of Sigerongan Village has implemented, with the hope that farmers will be able to take advantage the narrow land by planting intercropping. Cultivation of okra-peanut intercropping was more productive with an LER value of 2.28 compared to peanut monoculture and 1.35 compared to okra monoculture
Sekarang ini sawah tadah hujan di Lombok Selatan hanya bisa ditanami paling banyak dua kali (IP200) dengan pola tanam padi gora + palawija + bero. Padahal untuk menanam satu kali lagi masih memungkinkan karena sawah belum terlalu kering, apalagi dengan perubahan iklim dimungkinkan masih ada hujan. Teknologi sistem tumpang sisip (tusip) dapat mempercepat penen tanaman ketiga menggunakan tanaman genjah. Tusip dapat meningkatkan indeks pertanaman menjadi IP300. Tujuan kegiatan pengabdian ini adalah untuk meningkatkan indeks pertanaman (IP) menjadi IP300 (pola padi + kedelai + jagung) di lahan sawah tadah hujan melalui penerapan sistem tumpang sisip (tusip). Metode yang digunakan pada kegiatan pengabdian ini adalah metode Pendidikan Orang Dewasa (POD) atau Androgogi dengan menekankan partisipasi aktif dari peserta, kerja kelompok dan demonstrasi lapangan. Selain kegiatan penyuluhan juga dilakukan demplot untuk kegiatan pendidikan lapang di lahan sawah tadah hujan milik petani di dusun Mertak Lajut, Pujut, Lombok Tengah. Kegiatan ini dihadiri 21 peserta (Kepala UPT BPP Lajut, UPT BPP Pujut, PPL, Pimpinan UD. Humfik Tani, Kelompok Tani, dan petani sekitar). Berdasarkan hasil kegiatan pengabdian disimpulkan bahwa: 1). Peserta sangat antusias dan semangat mengikuti seluruh kegiatan mulai dari penyuluhan sampai kunjungan pertanaman demplot. 2). UD. Humfik Tani sebagai penangkar benih kedelai tertarik untuk mengembangkan kedelai varietas Derap-1 yang berumur genjah, berbiji besar, tahan hama penghisap polong. 3). Peserta berkomitmen untuk menerapkan sistem tumpang sisip untuk bisa mencapai IP300 di lahan masing-masing menggunakan varietas umur genjah. 4). Hasil ubinan demplot kedelai Derap-1 cukup tinggi mencapai 1 ton/ha biji kering. 5). Dengan menerapkan sistem tupang sisip, pola padi + kedelai + jagung (indeks pertanaman IP300) dapat direalisasikan di sawah tadah hujan Lombok Selatan.
