Effect of giberelin (GA3) concentration on growth and yield of Chinese kale (Brassica oleracea L. Var alboglabra) in various medium using hydroponic wick system . This research conducted from April until July 2016 in Wire House and Plant Physiology Laboratory, Department of Biology, Faculty of  Mathematics and Natural Science, Andalas University. The purposes of this research were to obtain GA3 concentration and planting medium that accelerate growth and yield of Chinese kale and determine the interaction between GA3 and planting medium to the gowth and yield of Chinese kale planted using hydroponics wick system. This research used Completely Randomized Design (CRD) in factorial with three replications, as the first factor were concentration of GA3 (0 ppm, 20 ppm, 40 ppm and 60 ppm) and the second factor were medium (zeolite, sand, husk and sawdust). The best result in accelerated the growth of Chinese kale was the treatment at the concentration of 60 ppm GA3 and zeolite was suitable medium to Chinese kale growth. This research found the interaction between GA3 and medium on the length of the roots Chinese kale used hydroponic wick system.

Abstract: The objective of this work was to evaluate the growth and yield of teak (Tectona grandis) stands at different spacing and in different soil classes. Twelve spacing were evaluated in an Inceptisol and Oxisol, in plots with an area of 1,505 or 1,548 m2, arranged in a completely randomized design with nine replicates. The teak trees were measured at 26, 42, 50, and 78 months of age. Total tree height was less affected by spacing. Mean square diameter was greater in wider spacing, whereas basal area and total volume with bark were greater in closer spacing. An increase in volume with bark per tree was observed with the increase of useful area per plant. For teak trees, growth stagnation happens earlier, the growth rate is higher in closer spacing, and the plants grow more in the Inceptisol than in the Oxisol.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya. Upaya peningkatan hasil bayam merah salah satunya dengan pemupukan untuk menambah nutrisi yang dibutuhkan tanaman. Tujuan dari penelitian ini adalah mempelajari respon pertumbuhan dan hasil tanaman bayam merah pada perlakuan dosis pupuk ZA. Pelaksanaan penelitian ini menggunakan Rancangan Acak Lengkap (RAL) satu faktor. Faktor yang diujikan adalah dosis pupuk ZA, terdiri 6 taraf, yaitu: tanpa pupuk ZA (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr /polybag (D5). Percobaan dilakukan dengan ulangan sebanyak 4 kali. Analisis data menggunakan analysis of variance (ANOVA), apabila berbeda nyata dilanjutkan uji Beda Nyata Terkecil (BNT) taraf 5%. Perlakuan dosis pupuk ZA berpengaruh nyata terhadap pertumbuhan dan hasil tanaman bayam merah. Perlakuan dosis pupuk ZA 1.2 gr/polybag (D3) menghasilkan tinggi, jumlah dan luas daun tanaman bayam merah tertinggi pada pengamatan umur 14, 21, dan 28 HST. Dosis pupuk ZA 1.2 gr/polybag (D3) juga menunjukkan berat basah dan berat kering tanaman tertinggi sebesar 49.15 dan 4.38 gram. Dosis ZA 1.2 gr/polybag merupakan dosis ideal untuk meningkatkan produktivitas tanaman bayam merah.
