Abstrak

Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi irigasi defisit terhadap pertumbuhan, hasil dan produktivitas air tanaman pada padi gogo (Oryza sativa L.) varietas Inpago 9. Penelitian ini dilaksanakan di dalam rumah plastik, laboratorium lapang terpadu, Universitas Lampung pada bulan November 2016 sampai dengan Maret 2017. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat taraf perlakuan, yaitu perlakuan ID1 ((0-20)-100)% AW, ID2 ((0-20)-80)% AW, ID3 ((0-20)-60)% AW, ID4 ((0-20)-40)% AW, dengan lima ulangan. Hasil penelitian menunjukkan bahwa, perlakuan irigasi defisit pada padi gogo (Oryza sativa L) varietas inpago 9 berpengaruh terhadap pertumbuhan tinggi tanaman, jumlah daun, jumlah anakan, jumlah malai, berat kering brangkasan atas, berat brangkasan bawah basah dan kering, dan gabah hampa. Namun tidak berpengaruh terhadap produksi dan produktivitas air . Faktor tanggapan hasil terhadap air (Ky) menunjukkan nilai > 1, artinya tanaman padi gogo varietas iv Inpago 9 sensitif terhadap irigasi defisit. Produktivitas air tanaman padi Inpago 9 rata-rata paling tinggi adalah ID1 dengan produktivitas 0,758 gram/liter, diikuti oleh ID4, ID3 dan ID2, masing-masing 0,756 gram/liter, 0,663 gram/liter, 0,575 gram/liter. Kata Kunci : irigasi defisit, fase tumbuh, padi gogo, dan produktivitas air tanaman. ABSTRACT The aim of this research was to determine the deficit irrigation applications on the growth, yield and crop water productivity of upland rice (Oryza sativa L.) variety of inpago 9. This research was conducted in a plastic house, at the integrated field laboratory at the University of Lampung from November 2016 to March 2017. This research used a completely randomized design (CRD) with 4 levels of soil water content, namely ID1 ((0-20)-100)% AW, ID2 ((0-20)-80)% AW, ID3 ((0-20)-60)% AW, ID4 ((0-20)-40)% AW, with five replicates. The result showed that deficit irrigation applications on upland rice (Oryza sativa L.) variety of inpago 9 had an effect on the growth of plant heigth, number of leaves, number of new shoots, number of panicle, the dry weight of biomass, weight of root, and empety grain. But it did not affect the production and water productivity. The factor of yield response to water (Ky) was more than 1, meaning that upland rice plant variety of inpago 9 was sensitive to deficit ii irrigation. The highest water productivity of rice plant of inpago 9 vatiety was ID1 with average productivity of 0,758 gram/liter, followed by ID4, ID3, ID2 respectively 0,756 gram/liter, 0,663 gram/liter, 0,575 gram/liter. Keyword: deficit irrigation, growth phase, upland rice, and crop water productivity
