Sebuah percobaan lapang untuk meneliti pengaruh jenis pupuk dan waktu penyiangan gulma pada pertumbuhan dan hasil tanaman jagung manis. Penelitian ini dilakukan sejak bulan Maret hingga Juni 2021 di lahan percobaan Fakultas Pertanian Universitas Brawijaya, Kelurahan Jatimulyo, Kecamatan Lowokwaru, Kota Malang, Jawa Timur dengan jenis tanah andosol. Penelitian ini dirancang dalam sebuah Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor dan 3 ulangan. Faktor pertama, ialah: Pupuk organik (P1), Pupuk anorganik (P2) dan Pupuk organik+anorganik (P3). Faktor kedua, ialah: Tanpa penyiangan (G0), Penyiangan 21, 42 hst (G1) dan Penyiangan 14, 28, 42 hst (G2). Hasil penelitian menunjukkan bahwa terdapat interaksi antara jenis pupuk dan waktu penyiangan pada bobot kering tanaman jagung manis umur 49 hst. Namun, perlakuan jenis pupuk dengan waktu penyiangan tidak berinteraksi pada hasil tanaman jagung manis. Perlakuan pupuk organik+anorganik dengan penyiangan 14, 28, 42 hst meningkatkan bobot kering tanaman. Perlakuan pupuk organik+anorganik dan pupuk anorganik memberikan pengaruh yang sama terhadap pertumbuhan dan hasil tanaman jagung manis. Penyiangan 14, 28, 42 hst tidak beda dengan penyiangan 21, 42 hst dalam mengendalikan pertumbuhan gulma serta mampu meningkatkan pertumbuhan dan hasil tanaman jagung manis. Pergeseran vegetasi gulma terjadi pada sebelum dan sesudah olah tanah pada setiap perlakuan.

APPLICATION OF GINGER PLANT CULTIVATION TECHNOLOGY IN THE YARD BASED ON HEALTH AGRICULTURE IN BOKOR VILLAGE, MALANG DISTRICT. House yard is one of the lands that have the potential to be developed. The yard can be used by growing high-value commodity crops. To get high yields and productivity, Farmers must choose the right and proper cultivation techniques. Besides, to get the results in the form of healthy food products, the cultivation process must be carried out by reducing the input of chemical compounds into the farm business. Therefore, community service activities were carried out in Bokor Village, Tumpang Subdistrict, Malang Regency. It was aimed to utilize the house yard by planting ginger based on healthy agriculture. The target group is farmers in the Subur Farmers Group. The stages of activities which were carried out were counseling on the use of house yards, training in ginger cultivation, providing assistance in planting materials and media, and making demonstration plots. The results of community service show that farmers want to try to use the yard by planting ginger in their yard. It also increased knowledge of farmers about ginger cultivation following Good Agricultural Practice so that the use of the yard with proper agriculture-based ginger cultivation can be developed.

Program pengabdian masyarakat ini berupa pelatihan teknologi budidaya tanaman bunga matahari di kelompok tani Desa Bokor. Kegiatan ini bertujuan untuk meningkatkan keterampilan teknologi budidaya tanaman bunga matahari di kelompok tani, dan memberikan pemahaman dan meningkatkan partisipasi masyarakat untuk membudidayakan tanaman bunga matahari. Program tersebut dilatarbelakangi oleh rencana desa untuk mengembangkan desa ke arah desa wisata. Keberadaan bunga matahari dapat menambah daya tarik dan nilai estetika lingkungan, sehingga dapat menarik wisatawan untuk berkunjung ke desa. Hal ini secara tidak langsung dapat meningkatkan kesejahteraan masyarakat dan menciptakan lapangan kerja baru. Kegiatan pengabdian telah dilaksanakan dari bulan Juli - November 2020 di Desa Bokor Kabupaten Malang. Metode pelaksanaan adalah metode Training of  Trainer (TOT). Tahapan metode pengabdian yang dilakukan meliputi perencanaan, persiapan, pelaksanaan kegiatan, monitoring dan evaluasi. Tim pengabdian masyarakat melakukan  monitoring secara daring dan luring/langsung turun ke lapangan, untuk melihat langsung kondisi tanaman dan berkomunikasi sekaligus berdiskusi dengan perwakilan petani. Di akhir kegiatan pengabdian, tim pengabdian juga melakukan pemberian bantuan benih tanaman bunga matahari yang bermutu tinggi. Hasil program pengabdian yaitu telah meningkatnya keterampilan teknologi budidaya tanaman bunga matahari di kelompok tani Desa Bokor, pemahaman dan partisipasi masyarakat untuk membudidayakan tanaman bunga matahari juga meningkat

Climate change has great impact on the availability of soil moisture for the production of food crops in the drylands. Objective of the research was to study climate change simulations on the availability of soil moisture in dry land in Unter Iwes District, Sumbawa Regency, West Nusa Tenggara Province.The method used for water balance calculations was Thornthwaite-Mather. Evapotranspiration calculations use the Penman Monteith model on the CROPWAT 8.0 model. The level of groundwater availability was obtained by analyzing groundwater content (KAT) data on the value of field capacity and permanent wilting point on dry land. The results revealed that changes in temperature and rainfall are factors that affect the water balance. The surplus occurred in January to March and the deficit occurred in April to November. The highest water-surplus was 244,2 mm m -1 in the Pelat Village and the lowest in Pungka Village was 225.5 mm m -1 . The highest deficit was 494.32 mm m -1 in Pungka Village and the lowest in Pelat Village was 475,59 mm m -1 . Increasing temperature and decreasing rainfall impact on water availability, thus reducing the surplus period at the study site. The deficit period shift occured only in scenarios accompanied by 10% rainfall (C1,C5 and C9). Decreased soil moisture availability and high demand for crop water affect the potential for reduction. The potential of corn yield reduction in Pelat Village is highest at 20,7% (C9 ΔT + 6 o C and ΔCH -10%). KEY WORDSClimate change, moisture availability, water requirement, drylands. 1 o C of Nino index in August caused the decline of rice production in the period of January-April next year by 10-20% in Java Island and more than 20% in South Sulawesi Province.
