Abstract

One of the problems on soybean production in North Kalimantan is the acidic soil conditions. The use of soybean varieties that are resistant to acidic soil conditions is an alternative to overcome this problems. Dena 1 and Devon 1 soybeans were the varieties that can be grown in acid soils. In addition to the right seeds, application of fertilizer is also needed to support the growth and grain yield of soybean. This study aimed to determine the interaction between varieties with Urea dosage on growth and grain yield of soybean varieties Dena 1 and Devon 1. The experimental design of this study was factorial randomized block design with two factors. The first factor was the soybean variety which consisted of: V1 = Devon 1 and V2 = Dena 1. The second factor was the Urea fertilizer dosage which consisted of four levels: P0 = Control, P1 = 1.32 g/plant, P2 = 2.64 g/plant, P3 = 5.28 g/plant. The results showed that there were no interaction between varieties and the Urea fertilizer dosage on growth and grain yield of soybeans. However, the variety independently had a significant effect on plant height and leaf width, which was shown by the Dena1 (V2) treatment.

Abstract

Keragaman genetik ubi jalar dapat dinilai berdasarkan analisis terhadap karakter-karakter tertentu. Tujuan penelitian ini adalah untuk melakukan pendugaan keragaman klon ubi jalar ungu berdasarkan karakter agronomi dan morfologi tanaman. Percobaan dilaksanakan selama musim hujan di Kebun Percobaan Ciparanje, Fakultas Pertanian Universitas Padjadjaran, Sumedang, Jawa Barat mulai November 2018 sampai April 2019. Perlakuan adalah 11 klon ubi jalar ungu yang berasal dari Indonesia, Peru, dan Jepang. Pengamatan terdiri atas karakter agronomi dan morfologi, serta komponen hasil. Pendugaan keragaman genetik menggunakan analisis klaster, analisis komponen utama, uji mantel, dan perhitungan ragam genotipik dan fenotipik. Hasil penelitian menunjukkan terdapat perbedaan keragaman genetik berdasarkan karakter agronomi dan karakter morfologi. Jarak genetik berdasarkan analisis klaster dan analisis komponen utama pada karakter agronomi dan morfologi masing- masing adalah 0,31–5,18 Euclidean dan 1,73–4,55 Euclidean. Korelasi keragaman agronomi dengan keragaman morfologi sangat lemah (r=0,096). Perhitungan ragam genotipik dan fenotipik juga menunjukkan bahwa keragaman karakter agronomi cenderung luas.

Abstract

This experiment aims to determine the effect of various concentrations of liquid fertilizer plus silica combined with N, P, and K inorganic fertilizers on the growth and yield of rice plants (oryza zativa). The trial was conducted in July 2018 to November 2018 in the Ciparanje experimental garden of the Faculty of Agriculture, Padjadjaran University, Jatinangor, Sumedang. The method used is Randomized Block Design (RBD) which consists of ten treatments with three replications; Treatment (A) Control, (B) standard NPK, (C) Plus Silica Liquid Fertilizer, (D) ¼ NPK + Silica Plus Liquid Fertilizer, (E) ½ NPK + Silica Plus Liquid Fertilizer, (F) ¾ NPK + Liquid Fertilizer Silica Plus, (G) NPK + Silica Plus Liquid Fertilizer, (H) ¾ NPK + ¼ Silica Plus Liquid Fertilizer, (I) ¾ NPK + ½ Silica Plus Liquid Fertilizer, (J) ¾ NPK + ¾ Silica Plus Liquid Fertilizer. The results showed that there was an effect of silica fertilizer on the growth and number of tillers after rice 8 MST. The treatment of F (¾ NPK + Liquid Fertilizer Plus Silica) gave the highest value to the yield of rice plants with the results of 53.31 gr of crop.
