Abstract

Tujuan penelitian adalah untuk mendapatkan dosis pupuk NPK yang tepat dalam meningkatkan pertumbuhan dan hasil tanaman padi gogo. Penelitian ini dilaksanakan di Pusat Pengembangan dan Penelitian Padi Gogo Fakultas Pertanian, Universitas Tadulako, Dusun Kalama, Desa Tamarenja, Kecamatan Sindue Tobata, Kabupaten Donggala pada LS 00o26’51.4” BT 119o49’50.5, dengan ketinggian tempat 230 mdpl. Waktu penelitian dimulai dari bulan November sampai Maret 2021. Penelitian ini disusun menggunakan Rancangan Acak Kelompok (RAK) dengan dosis pupuk NPK Majemuk pebagai perlakuan: Tanpa NPK, dosis 100 kg/ha, 200 kg/ha, 300 kg/ha, 400 kg/ha, 500 kg/ha, dan 600 kg/ha. Perlakuan ini diulang sebanyak 4 kali sehingga terdapat 28 unit percobaan. Data yang diperoleh dianalisis dengan menggunakan analisis varian yang kemudian dilanjutkan dengan uji BNT taraf 5%. Hasil penelitian menunjukkan bahwa pemberian pupuk NPK dosis 400 kg ha-1 nyata meningkatkan hasil prouksi padi gogo dengan ditandai adanya peningkatan jumlah anakan, jumlah anakan produktif, dan produksi gabah.

Abstract

The relationship between several characters of yields is very important for developing effective selection criteria. The total correlation between the result character and the result component may be misleading as a result of its relationship with other characters. Separating the total correlation into direct and indirect effects provides a more significant explanation of the cause of the relationship between dependent variables such as yield and independent variables such as yield components. This study aims to determine several traits that can be used to make selections indirectly and directly to increase the yield of upland rice. This research has been carried out on agricultural land in the village of Tamarenja (Kalama), Sindue District, Donggala Regency. Starting from August to December 2019, using a Randomized Block Design (RBD) with seven genotypic cultivars and three groups of cultivars so that there were twenty one experimental plots. The results showed that the number of leaves, leaf length, number of tillers, number of productive tillers, flowering age, thickness of seeds and weight of 1000 grains had a positive and significant correlation to yield. Flowering age, 1000 grain weight, and number of tillers are some of the characteristics that have a high direct effect and significant correlation to upland rice yield.
