Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pencucian dan ameliorasi terhadap sifat kimia tanah dan air dalam menunjang pertumbuhan tanaman padi di lahan sulfat masam bukaan baru. Penelitian ini meliputi pembuatan kompos berbahan dasar tanaman lokal di kebun percobaan Belandean yang dilanjutkan dengan percobaan pot di rumah kaca Balittra Banjarbaru, Kalimantan Selatan pada bulan Februari sampai Mei 2019. Rancangan yang digunakan dalam penelitian ini adalah rancangan acak lengkap (RAL) faktorial 2 faktor dan diulang sebanyak 3 ulangan. Faktor pertama adalah pemupukan (P), yaitu: (a) P0 = tanpa dipupuk,  (b) P1 = pemupukan NPK 50% dosis rekomendasi, (c) P2 = pemberian NPK 50% dosis rekomendasi + Kompos, (d) P3 = pemberian NPK 100% dosis rekomendasi + NPK anorganik sesuai kandungan kompos, dan (P4) = pemberian NPK 100% dosis rekomendasi. Faktor kedua adalah pencucian (D) dengan sistem, yaitu: (a) D0 = air hasil pencucian tidak dikembalikan, (b) D1 = air hasil pencucian dikembalikan. Hasil penelitian menunjukkan bahwa pencucian dengan air hasil pencucian tidak dikembalikan membuat  nilai Eh, DHL serta kandungan Fe dan SO4 tanah lebih rendah jika dibandingkan dengan perlakuan lainnya. Namun, nilai Al-dd dan H-dd tanah terendah terdapat pada perlakuan pengembalian air hasil pencucian dan pemupukan NPK 50% dosis rekomendasi dengan penambahan kompos bahan organik insitu. Perlakuan ini juga memiliki nilai produksi biomassa tertinggi jika dibandingkan dengan perlakuan lainnya.

Abstract

Fusarium wilt of shallot is caused by Fusarium solani could affect yield on shallot planting. This research was conducted to study the effect of  addition urea fertilizer on total nitrogen of soil, ammonium, nitrate, nitrogen uptake of foliage and bulbs, and bulbs yield of shallot. This research was conducted at KP4 Kalitirto Berbah and Faculty of  Agriculture, Gadjah Mada University with Randomized Complete Block Design (RCBD) with 2 factors and 4 replications. The first factor was two type of soil which were inoculated soil by Fusarium solani inoculums and sterilized soil by heating  treatment at more than 100 °C at least 3 hours. The second factor was five different dose of urea and KCl fertilizer on percentage (0, 50, 100, 150 and 200) from fertilizer recommendation. The result showed that total nitrogen of soil, ammonium, nitrate in inoculated soil lower  compared to sterilized soil. There is a positive and significant correlation between ammonium and total nitrogen of soil to fresh weight of bulb, the number of bulb and nitrogen uptake of foliage. Likewise, the fresh weight of bulbs and the number of bulb has a positive and highly significant correlation with nitrogen uptake of foliage and nitrogen uptake of bulb.

Abstract

The mentoring and demonstration plot program with the application of technology carried out by the Faculty of Agriculture Universitas Gadjah Mada Team was proven to be able to increase the productivity and quality of soybeans, although some were only applied partially (not completely) from the recommended technology package, this was constrained by many factors in each mentoring area. In the Cilacap area, the demonstration plot results showed a fairly high potential reaching 2.24 tons/ha in Bantarsari, 2.94 and 3.77 tons/ha in Kawunganten, while in Majenang before harvesting soybeans showed good potential with 130-140 pods. per plant, this is of course the potential yield can reach above 3.0 tons/ha, but unfortunately it was affected by the flood due to the broken embankment, so the soybeans were inundated and damaged (rotten) in a relatively short time. The process of technology transfer and adoption that occurred went well, and many farmers gave testimony that this mentoring program was good to be developed and continued, so that under conditions according to the growing season, they would be able to show even better potential.
