Penelitian bertujuan mengetahui pengaruh amelioran lokal dan biofertilizer terhadap pertumbuhan dan hasil koro pedang di tanah grumusol. Dilakukan dengan faktorial 2 x 3, RAKL, tiga kali ulangan. Faktor pertama: macam amelioran lokal terdiri atas pupuk kandang ayam dan pupuk hijau gliricidae. Faktor kedua: macam biofertilizer: kontrol (tanpa biofertilizer), Mikoriza, dan Rhizobium. Variabel pengamatan: tinggi tanaman, jumlah daun, jumlah cabang produksi, bobot segar tanaman, bobot kering tanaman, persentase bintil akar aktif, jumlah polong per tanaman, panjang polong per tanaman, bobot 100 biji, bobot polong kering per tanaman, dan hasil biji per hektar. Analisis hasil menggunakan sidik ragam taraf signifikan lima persen, dilanjutkan uji DMRT taraf lima persen. Hasil: tidak terjadi interaksi antara macam amelioran lokal dan macam biofertilizer terhadap pertumbuhan dan hasil. Ada beda nyata perlakuan macam amelioran lokal terhadap tiga variabel pengamatan: jumlah polong, bobot kering polong, dan hasil biji per hektar. Pemberian pupuk kandang ayam mampu meningkatkan hasil biji lebih baik dibanding pupuk gliricidae. Pemberian rhizobium memberikan hasil lebih baik dibanding mikoriza dan kontrol pada hasil biji per hektar.

This study aims are to know the influence of organic fertilizers and the depth of soil tillage on growth and yield of jack bean cultivated in grumusol soil as marginal land. The research was conducted in Playen Village, Yogyakarta Indonesia having latitude 250 m above sea level. The research used 4 x 3 factorial experiment arranged in Randomized Complete Block Design with 3 replications. The first factor is the kinds of organic fertilizers consisting of 4 levels: green manure, cow manure, goat manure, and chicken manure. The second factor is the depth of soil tillage: 15 cm, 30cm, and zero tillage as control. Results of the experiment indicate that the application of glirisidea green manure on the 30 cm depth of soil tillage could result the longest pod length and highest quantity number of leaves. The application of glirisidea green manure could result higher seed yield per ha-1 than that of chicken manure, cow manure as well goat manure. The 15 cm as well as 30 cm depth of soil tillage could result pod number, pod weight and 100 seed weight higher than that of without soil tillage.

Tujuan penelitian adalah efek dari penggunaan amelioran lokal dikombinasikan dengan interval penyiraman terhadap pertumbuhan dan kualitas kacang pedang (Canavalia ensiformis.L) di daerah pasir pantai dilakukan dari bulan Mei sampai September 2014 di Depok Pantai Parangtritis, Bantul Yogyakarta . Penelitian disusun dalam Rancangan Petak Terbagi dengan tiga ulangan. Plot utama penyiraman selang yang terdiri dari dua tingkat: penyiraman setiap hari dan penyiraman setiap dua hari. Anak petak adalah kombinasi antara jenis bahan organik dan aplikasi dosis tanah liat. Jenis bahan organik yang terdiri empat tingkatan: kotoran ayam, kotoran kambing, kotoran sapi, dan daun hijau gliricidae. Dosis tanah liat terdiri dari dua tingkat: tanah liat dosis 10 ton ha -1 dan tanah liat dosis 20 ton ha-1. Hasil penelitian menunjukkan bahwa penyiraman setiap hari dalam kombinasi dengan penerapan daun hijau glirizidae menghasilkan tinggi tanaman, jumlah daun, akar nodul lebih baik dari aplikasi lain. Penerapan daun hijau glirizidae dalam kombinasi dengan aplikasi dosis tanah liat 20 ton ha-1 menghasilkan jumlah polong dan bobot 100 biji lebih tinggi dari aplikasi lainnya. Aplikasi pupuk dapat membuat struktur tanah yang lebih baik dari tanah pantai berpasir.Study dealing with the use of local ameliorant in combination with the interval of watering on the growth and quality of sword bean (Canavalia ensiformis.L) in sand beach area was conducted from May until September 2014 in Depok Beach Parangtritis, Bantul Yogyakarta. The experiment was arranged in Split Plot Design with three replications. The main plot was watering interval consisting of two levels: watering every day and watering every two days. The sub plot was the combination between the kind of organic matter and the clay dosage application. The kind of organic matter consisting of four levels: chicken manure, goat manure, cow manure, and green leaves of gliriside. The clay dosage consisting of two levels: clay dosage 10 ton ha -1 and clay dosage 20 ton ha-1. Results of the experiment indicated that the watering every day in combination with the application of green leaves of gliriside resulted plant height, leaves number, root nodules better than the other applications. The application of green leaves of gliriside in combination with the clay dosage application 20 ton ha-1resulted pod number and the weight of 100 seeds higher than the other application. The application of manure can create better soil structure of sandy beach land.

Research conducted in experimental field of Agricultural Faculty of Sarjanawiyata Tamansiswa University from October until November, 2010. Experiment used factorial 2x4 arranged in Split-Plot Design. Main-plot was environmental planting condition: open field and plastic tunnel. Sub-plot was fertilizer: urea, NPK, chicken manure, Bokashi. Treatments replicated in three replications. Observations: fresh weight, dry weight, N total, and Cation Exchange Capacity (CEC). Result: no interactions between environmental planting conditions and fertilizer various on fresh weight, dry weight, and CEC. There was interaction between environmental planting conditions and fertilizer various on N total content. Plastic tunnel resulted higher both on fresh weight and dry weight than that of open field. Compare to open field, there was no significantly different effect of plastic tunnel on CEC. Application of Bokashi could produce fresh weight as well as dry weight higher than that of application of chicken manure, NPK as well as urea. Under open field condition, there were no significantly different on N total content of the plants treated by urea, NPK, chicken manure as well as bokashi. Whereas under plastic tunnel condition, both application of bokashi and NPK resulted in higher N total content than application of chicken manure as well as urea. Key-words: spinach; plastic; fertilizer1 Author’s address for correspondence: Sri Endah Prasetyowati, Agriculture Faculty of Sarjanawiyata Tamansiswa University Yogyakarta, Indonesia.
