Abstract

Ketersediaan air mempengaruhi faktor pertumbuhan tanaman padi yaitu fisiologi, morfologi, pola pertumbuhan dan hasil padi. Tujuan penelitian ini adalah mengetahui respon beberapa varietas padi sawah dengan tinggi muka air yang berbeda dan mendapatkan varietas padi sawah yang terbaik dan tinggi muka air yang sesuai terhadap hasil tanaman padi sawah. Penelitian lapang ini dilaksanakan di Desa Cipta Karya, Kecamatan Sungai Betung, Kabupaten Bengkayang. Penelitian dilaksanakan selama lima bulan, sejak bulan Februari sampai  Juni  2020. Penelitian ini menggunakan metode eksperimen lapangan dengan pola Rancangan Acak Lengkap Faktorial (RALF) yang terdiri dari 2 faktor dan diulang sebanyak 3 kali. Faktor  pertama adalah varietas padi (V) sebanyak 4 taraf yaitu varietas Cilosari, Ciherang, Inpari 39 dan Inpago 8 dan faktor kedua adalah tinggi muka air (A) sebanyak 5 taraf yaitu -5 cm, 0 cm, 5 cm, 10 cm dan 15 cm.  Pengamatan tanaman meliputi tinggi tanaman, jumlah anakan maksimum, jumlah anakan produktif, umur berbunga, jumlah gabah isi per malai, panjang malai, persentase gabah isi per malai, bobot 1.000 butir dan bobot gabah kering panen per rumpun. Hasil penelitian menunjukkan varietas dan tinggi muka air sangat berpengaruh nyata terhadap komponen pertumbuhan yaitu tinggi tanaman, jumlah anakan maksimum Varietas Cilosari, Inpari 39 dan Inpago 8 memberikan bobot gabah tertinggi yaitu masing-masing sebesar 36,93, 32,40 dan 31,89 g per rumpun.  Perlakuan tinggi muka air 5 cm memberikan bobot gabah tertinggi sebesar 37,92 g per rumpun.

Abstract

The application of various types of organic matter as ameliorant and NPK fertilizer can increase the fertility of ultisol soil, physically and chemically. The study aimed to determine the effect of ameliorant types, the dose of NPK fertilizer and their interaction on the growth and development of glutinous corn on ultisol soil. The research was conducted in Bengkayang Regency, West Kalimantan from March to August 2020. The research used a factorial randomized block design. The first factor was the types of ameliorants with 5 levels, namely corncob biochar, corn waste bokashi, rice straw bokashi, cow manure, and chicken manure. The second factor was the dosage of NPK fertilizer with 4 levels, i.e., 100, 200, 300, and 400 kg ha-1. The chicken manure ameliorant increased plant height 2, 4, and 6 WAP (weeks after planting), ear diameter, ear length, ear weight per ear, and ear weight per plot. The best dose of NPK fertilizer for glutinous maize production is 200 kg ha-1 on ear length and weight per ear, and a dose of 100 kg ha-1 can stimulate plant growth based on plant height of 4 WAP. The combination of chicken manure and NPK fertilizer of 400 kg ha-1 produced the highest root dry weight, crown dry weight, and relative growth rate. Keywords: crop production, inorganic fertilizers, organic matter, soil fertility

Abstract

Adaptive varieties and N, P, and K fertilization can increase rice productivity. The study aimed to determine the effect of N, P, and K fertilizer dosages on the growth and yield of several rice varieties on alluvial soil. The research was conducted in Kubu Raya Regency, West Kalimantan, from March to October 2023. The method used a factorial randomized complete block design with three replications. The first factor was rice varieties (Argo Pawan, Bima Saputra, Inpari 43, Padang, and Tropiko). The second factor was N, P, and K fertilization (150 kg N ha-1+ 100 kg P2O5 ha-1 + 100 kg K20 ha-1; 300 kg N ha-1 + 200 kg P2O5 ha-1 + 200 kg K20 ha-1; 450 kg N ha‑1 + 300 kg P2O5 ha-1 + 300 kg K20 ha-1). The Tropiko variety had the highest plant height compared to other varieties. The Inpari 43 variety produced the highest maximum number of tillers. Furthermore, the Inpari 43 and Tropiko varieties were the best treatments for producing the number of productive tillers and grain weight per plot. The N, P, and K fertilizer dosage of 300 kg N ha-1 + 200 kg P2O5 ha-1 + 200 kg K20 ha-1 was the best treatment in producing growth and yields of rice plants based on the variables of maximum number of tillers, number of productive tillers, and grain weight per plot. Keywords: adaptive varieties; rice productivity; soil fertility
