Penggunaan umbi sebagai benih tanaman bawang merah memerlukan waktu penyimpanan yang lama sebelum ditanam, memerlukan jumlah berat dan volume yang besar untuk ditanam pada areal pertanaman, serta sulit didistribusikan antar daerah. Alternatif lain dalam praktek budidaya tanaman bawang merah adalah dengan menggunakan benih biji (True Shallot Seed). Kendala dalam produksi TSS yang sangat menonjol adalah pembungaan yang tidak serempak dan diperlukan bantuan polinator atau serangga penyerbuk untuk meningkatkan seedset-nya. Lalat hijau dan lebah madu banyak berperan dalam penyerbukan bunga bawang merah. Penelitian ini bertujuan untuk mendapatkan jenis polinator yang efektif membantu penyerbukan dalam meningkatkan hasil biji dan mengevaluasi asupan hara terhadap peningkatkan hasil biji dan umbi bawang merah. Asupan hara dengan pupuk anorganik dan organik, serta polinator dengan lebah madu dan lalat hijau. Untuk merangsang pembuangan dilakukan vernalisasi. Kesimpulan : pupuk anorganik Mutiara dan pupuk Organik Compound Super-MS dengan dosis masing-masing 150 kg/ha dan 1 t/ha meningkatkan jumlah anakan per rumpun, jumlah bunga per umbel, bobot biki per umbel, dan bobot kering per rumpun. Vernalisasi nyata mempercepat pembungaan dan jumlah bunga perpetak dan jumlah bunga per umbel. Polinator lebah dan lalat hijau efektif meningkatkan jumlah biji per umbel dan bobot biji per umbel.

Tujuan umum penelitian ini adalah memetakan potensi produksi emisi metana pada lahan sawah organik di Desa Sukorejo dan Jetis, Kecamatan Sambirejo, Sragen, yang dapat digunakan untuk memitigasi emisi metana dan meningkatkan produktivitas lahan. Secara garis besar pelaksanaan penelitian dibagi menjadi 4 tahap ; (1) karakterisasi tanah dan lahan, pengungkapan secara mendalam karakter obyek lahan pada setiap satuan penggunaan lahan sawah, (2) pengukuran potensi produksi emisi metana, dengan metode inkubasi sampel tanah di laboratorium, sampel gas yang dihasilkan dianalisis menggunakan kromatografi gas yang dilengkapi dengan flame ionization detector (FID) untuk menetapkan flux CH4, (3) analisa data, taraf perbedaan nilai potensi produksi metana diketahui dengan analisis beda nyata Uji T, dan penentuan faktor yang paling berperan terhadap besarnya potensi emisi metana dengan analisis stepwise regression, dan (4) rekomendasi, pemilihan rekomendasi didasarkan pada praktek budidaya pertanian yang efektif meningkatkan C organik dan menekan produksi emisi metana tanpa mengurangi produktivitas tanaman. Hasil penelitian menunjukkan bahwa ; (1) potensi produksi metana (CH4) berbeda nyata antar satuan penggunaan lahan (SPL) sawah di Desa Sukorejo dan Jetis, (2) iklim, varietas tanaman dan cara budidaya di daerah penelitian tidak signifikan mempengaruhi besarnya potensi produksi metana, dan (3) faktor yang berpengaruh signifikan terhadap besarnya potensi produksi metana di tanah sawah adalah potensial redoks (Eh). Hubungan Eh dengan besarnya potensi produksi metana berkorelasi negatif, artinya penurunan Eh akan menyebabkan peningkatan produksi metana. Mitigasi emisi GRK metana yang dapat dilakukan berdasarkan penelitian ini, bahwa potensial redoks adalah faktor utama penentu potensi produksi metana di dalam tanah sawah, maka alternatif yang memungkinkan adalah dengan pengelolaan air irigasi, yang dalam periode tertentu tanaman padi tidak diairi atau tidak digenangi, atau apabila kondisi air berlebih dilakukan drainase. Usaha ini dilakukan dengan tujuan kondisi tanah tidak terlalu reduktif atau potensial redoks tidak akan turun secara drastis, sehingga akan dapat menghambat aktivitas mikrobia methanogen dalam memproduksi metana.
