Abstract

Sridanti et al, 2019. Effectiveness of Time and Dosage for Giving NPK to the Production of Sweet Corn (Zea mays saccharata Sturt) in the Highlands. pp. 28-31. Sweet corn plants will not provide maximum results if the nutrients needed are not enough. Fertilization can increase yields quantitatively and qualitatively. The purpose of this study was to determine the effect of fertilizing time and the ideal dose for sweet corn. This research was carried out in Mojorejo Village, Selupu Rejang District, Rejang Lebong Regency at an altitude of + 0.050 meters above sea level (m asl). This study uses Factorial Randomized Block Design (RAKF). Observations and measurements were carried out on the main variables in the form of fruit weight, ear length and ear diameter without cornhusk (generative parts) as well as supporting variables such as plant height and number of leaves (vegetative parts). All data are analyzed by variance, and if F table is greater than F, the count is tested further using DMRT. The results showed 50 grams of NPK fertilizer significantly different from the average plant height and not significantly different from fertilization time.

Abstract

Tujuan penelitian ini adalah untuk mengetahui respon pertumbuhan berbagai genotipe kopi arabika di dataran tinggi Jang Hiang Bong dan mendapatkan genotipe kopi arabika potensial untuk dibudiayakan pada dataran tinggi Jang Hiang Bong. Percobaan ini menggunakan Rancangan Acak Kelompok Lengkap yang dilaksanakan di Kebun Percobaan Universitas Pat Petulai. Parameter yang diamati dalam penelitian ini adalah tinggi tanaman, diameter batang, luas kanopi, luas sepasang daun, dan jumlah cabang produktif. Secara keseluruhan, hasil penelitian menunjukkan setiap genotipe menampilkan respon pertumbuhan yang berbeda-beda. Respon pertumbuhan terbaik didapatkan pada perlakuan G6 (Genotipe M-97), yang menunjukkan pengaruh positif terhadap tinggi tanaman, luas kanopi, dan jumlah cabang produktif. Semua perlakuan menunjukkan respon yang tidak berbeda nyata terhadap diameter batang dan luas sepasang daun.
