Abstract

Kartikawati et al, 2017. Utilization of Rainfed Rice Areas for High Yielding Rice Cultivation on Climate Change. JLSO 6(2):142-149.Many efforts have been conducted by Indonesian government for national food supply and food security through rice cultivation on sub optimal lands in accelerating food sustainability particularly rice, maize and soybean. The rainfed area is an important sub optimal land which should be developed due to 26,5% of Indonesia rice production produced from cultivation system in those area. However, the cultivation in rainfed areas have challenges such as changing of rainfall pattern due to climate change. Therefore, to obtain the information of productivity from high yield rice varieties and methane emission in rainfed area, a study has been conducted by applying innovation of environmental friendly technology such as fertilizer use based on integrated cropping calendar. The study was carried out at Research Station of Indonesian Agriculture Environment Research Institute in Jakenan, which is one of rainfed area in Pati District, Central Java Province. The study was conducted on first growing season (GS 1) or rainy season by applying direct seeded system using rice seeder. Four rice varieties were used for this study, namely Ciherang, Dendang, Inpari 31 and Inpari 24. The study showed that productivity of four rice varieties were 5.92; 7.10; 5.06 and 7.41 t/ha, respectively. Methane emission was significant different among the varieties as 232; 319; 300 and 405 kg/ha/season, respectively.

Abstract

Perubahan iklim, serangan hama dan penyakit merupakan beberapa faktor yang berpengaruh terhadap produksi dan produktivitas tanaman padi (Oryza Sativa L.). Pendekatan teknologi pertanian ramah lingkungan diharapkan mampu meningkatkan produksi dan produktivitas tanaman padi secara berkelanjutan. Penelitian ini bertujuan untuk mengetahui produktivitas empat varietas padi serta intensitas serangan hama dan penyakit pada penerapan teknologi pertanian ramah lingkungan. Penelitian ini dilaksanakan di lahan sawah tadah hujan di Kecamatan Jaken, Kabupaten Pati dari Bulan November 2019 – Maret 2020. Penelitian ini menggunakan metode purposive sampling dengan rancangan acak kelompok. Varietas padi menjadi faktor tunggal dalam penelitian ini. Varietas padi yang digunakan terdiri dari Inpari 32, Cigeulis, Inpari 43 dan M400, masing-masing diulang 4 kali. Komponen teknologi pertanian ramah lingkungan yang digunakan yakni penggunaan biochar-kompos (biokompos), urea berlapis arang atau biochar, serta penggunaan biopestisida sebagai pengendalian hama penyakit. Pengamatan dilakukan terhadap pertumbuhan, produktivitas dan intensitas hama penyakit. Hasil penelitian menunjukkan bahwa tinggi tanaman varietas Inpari 32 (101.22 cm) dan Cigeulis (102.19 cm) lebih tinggi dibandingkan varietas Inpari 43 (94.72 cm) dan M400 (92.31 cm). Varietas M400 memiliki jumlah anakan (21.11) dan jumlah malai (17.83) tertinggi dibandingkan varietas Inpari 32, Cigeulis dan Inpari 43. Varietas Inpari 32 dan Inpari 43 menghasilkan produktivitas tinggi, berturut-turut yakni 5.83 dan 4.91 t/ha dibandingkan Cigeulis (2.12 t ha-1) dan M400 (1.08 t ha-1). Hama yang menyerang yakni penggerek batang padi kuning (PBP) dengan intensitas serangan tertinggi 89.47% pada varietas M400 dan hama wereng batang coklat sebesar 7.69% pada varietas Cigeulis. Intensitas serangan penyakit blas dan hawar daun bakteri tertinggi masing-masing yakni 14.97% dan 5.99% pada varietas M400.
