Abstract

Kegiatan pengabdian masyarakat yang dilakukan di Desa Bendosari, Blitar ini bertujuan untuk meningkatkan efisiensi dan kualitas produksi pakan ternak melalui teknologi modern. Tantangan utama yang dihadapi adalah penyumbatan mesin pencacah pakan ternak dan kesesuaian media tanam untuk perkecambahan Indigofera. Solusi yang diterapkan mencakup pengembangan mesin pencacah dan pelet pakan ternak, analisis media tanam optimal untuk Indigofera skala laboratorium, dan pelatihan penggunaan mesin serta budidaya Indigofera. Tujuan kegiatan ini adalah untuk meningkatkan efisiensi produksi pakan dan keterampilan petani dalam menggunakan teknologi baru, serta menentukan media tanam terbaik untuk Indigofera. Mitra yang terlibat dalam kegiatan ini adalah Kelompok Tani Ben Giat Tani sebagai pengguna teknologi dan peneliti dari BRIN yang berkontribusi dalam penelitian media tanam dan uji tanah. Pelatihan dan modul operasional disediakan untuk meningkatkan keterampilan petani. Kegiatan ini mendukung Tujuan Pembangunan Berkelanjutan (SDGs) dengan meningkatkan produksi pangan (SDGs 2), pekerjaan layak dan pertumbuhan ekonomi (SDGs 8), inovasi industri (SDGs 9), konsumsi dan produksi yang bertanggung jawab (SDGs 12), serta konservasi ekosistem darat (SDGs 15).

Abstract

Cowpea (Vigna unguiculata L. Walp), a botanical protein source, exhibits resilience in the face of drought-induced stress on rainfed rice fields, especially in dry season crop patterns. Cowpea growth depends on the availability of nutrients in the soil, including potassium (K). In fact, low K availability (exchangeable K is ≤ 0.04 cmol(+) kg-1) is one of the obstacles in rainfed rice fields, especially in increasing crop yields, including cowpea. Therefore, K supplies from various sources are needed to improve soil and cowpea productivity, such as K fertilizer and manure. This study was carried out to determine the response of nutrient management to increase cowpeas’ yield and exchangeable potassium on rainfed rice fields. The field experiment used a randomized block design, with six replications and six fertilizer management treatments, specifically to control composted cattle manure (CCM), Nitrogen Phosphate Fertilizer (NP), CCM+NP, NPK Fertilizer, and CCM+NPK. The parameters observed include plant height, yield components, seed yield, and exchangeable K. Fertilizer management affects the cowpea yield, yield components, K-Uptake, and exchangeable potassium, with the best treatment depicted as CCM+NPK treatment. Compared to the control, CCM by itself and in combination with inorganic fertilizer increases the kernel yield of cowpea by as much as 54-104%, K uptake as much as 40.9-68.2 kg K/ha, and exchangeable K in soil ranging from 37.8-101.3%. It is indicated that the CCM could supply nutrients, including potassium, to overcome potassium deficiency in rainfed rice fields. Furthermore, applying CCM and cultivating cowpeas in rainfed rice fields during the dry season, with water as a limiting factor, is an appropriate option to enlarge the plant yield.

Abstract

Nitrous oxide (N2O) emissions from agricultural activities contribute significantly to global warming. Understanding the factors influencing N2O emissions is crucial for developing effective mitigation strategies. This review assesses N2O emissions from various crops cultivated in tropical mineral and peatland soils, providing insights into the impact of land use, fertilization practices and rainfall on N2O fluxes. Field measurements of N2O fluxes were conducted in agricultural fields growing corn, peanuts, and cassava in Bogor Regency, West Java Province, as well as in peatland areas with Acacia plantations and natural primary forests in Bengkalis Regency, Riau Province. The study assesses the total N2O fluxes for each crop and land type, revealing significant variations in N2O emissions among different crops and land uses. Peatland areas exhibit higher emissions compared to mineral soils, emphasizing the need for targeted mitigation measures in these ecosystems. The findings highlight the importance of considering the type and age of land use when evaluating N2O emissions. Land management practices, such as fertilizer use and soil disturbance, emerge as critical factors affecting N2O emissions. Improper fertilizer application and excessive soil disturbance can lead to increased N2O emissions, underscoring the necessity for careful N fertilizer management and conservation tillage techniques.
