Abstract

The objective of this research was to determine the most effective type of manure for supporting the initial growth of clove seedlings. The study was conducted between October 2021 and February 2022 at Tadulako University's Faculty of Agriculture Screen House in Palu. Chicken, cow, goat, and sheep manure were each added to the planting medium at a ratio of 2:1 (v/v) and compared to non-manure treated media. Although the results indicated that none of the different types of manure had a significant impact on the growth of clove seedlings, cow manure showed some promise in terms of promoting clove height, leaf number, leaf area, and stem diameter.

Abstract

The research aimed to discover the response of the growth of two spinach species on Nutrient Film Technique (NFT) hydroponic system and the concentration of the appropriate AB Mix solution on each species. The research was conducted in January to February 2016, at Green House, Faculty of Agriculture, Tadulako University by using Split Plot Design method. The main plot was red and green spinach, while the subplot was the concentration of AB Mix nutrient solution, namely 4 ml/L of water, 5 ml/L of water, 6 ml/L of water and 7 ml/L of water. The research findings reveal that AB Mix nutrient solution was generally very good to support the growth of spinach on NFT hydroponic. The green spinach had better response rather than the red one. There was no interaction between species and the concentration of nutrient solution. The good concentration of nutrient solution for green spinach is 6 ml/L. It was showed by the better growth of plant height on all age of plant, the more number of leaves, the canopy and the root (wet and dry) were heavier, while on the red spinach, 5 ml/L of concentration of nutrient solution resulted in the best growth, yet it was not significantly different from other concentration except on the parameter of plant height and the dry weight of plant canopy.

Abstract

Onion (Allium ascolanicum L.) is not only popular as cooking spices in Indonesia but also throughout the world. Onion that has high economic value, has its own attraction to be cultivated by farmers. However, farmers often face some problems in onion farming. Problems were faced by farmers related to social economic conditions both internal, external and natural conditions. Fertilizer application for onion can use inorganic and organic fertilizer materials. The use of inorganic fertilizers without the addition of organic fertilizers over a long period of time, suspected to cause a decrease in soil physical and chemical capabilities, with the application of solid and liquid organic fertilizer is predicted to be more effective because the elements are more than one element. The use of fertilizers and organic matter through soil is often inefficient because of the fixation by soil particles. Liquid fertilizers administered overcome gapnutrients during growth. Herbafarm liquid organic fertilizer is a type of liquid fertilizer released by PT. Sidomuncul herbafarm which contains bio protectant, processed from by products of medicinal products made from raw medicinal plants and spices. Herbafarm contains macro and micro nutrients and also organic compounds that are essential for the growth and development of plants. This research was conducted in Sidera village, Biromaru sub-district, Sigi regency, Central Sulawesi Province. This study used a Randomized Block Design consisting of 5 treatment levels: P0 = control, P1 = 1 ml/liter of water, P2 = 2 ml/Liter of water, P3 = 3 ml/liter of water, and P4 = 4 ml/liter of water. All treatments were repeated 4 (four) times, so that there were 5 treatments each time 4 replicates = 20 experimental units. The results of this research were the best herbafarm POC on the treatment of 4 ml/liter of water that was on the parameters of plant height of 33,56 cm, leaves number as much as 30. 63 blades, total dry weight of crop 9.99 g, number of tubers per family of 8.13 fruit, tuber diameter of 20.26 mm, tuber length of 34.55 mm, fresh tuber weight per family of 32.57 g, tuber water content of 114.54 g and Weight of tuber per hectare 8.68 ton.ha-1.

Abstract

Pertumbuhan tanaman dalam kultur jaringan ditentukan oleh berbagai faktor, seperti jenis eksplan dan komposisi ZPT yang digunakan. Penelitian ini bertujuan untuk menguji pengaruh dari jenis eksplan, komposisi ZPT serta kemampuan pertumbuhan setiap jenis eksplan pada berbagai komposisi ZPT yang dicobakan. Penelitian ini dilaksanakan di Laboratorium Bioteknologi Fakultas Pertanian Universitas Tadulako dari bulan Oktober 2022 sampai Februari 2023. Penelitian ini disusun berdasarkan pola Rancangan Petak Terpisah dengan menggunakan Rancangan Acak Lengkap. Petak utama adalah jenis eksplan yang terdiri atas dua aras, yaitu pangkal dan pucuk. Anak petak adalah komposisi zat pengatur tumbuh yang terdiri atas empat kombinasi, yaitu 1). 2 ppm BAP + 0,2 ppm NAA; 2). 3 ppm BAP + 0,4 ppm NAA; 3). 3 ppm Kinetin + 0,2 ppm NAA; 4). 3 ppm Kinetin + 0,4 ppm IAA. Setiap kombinasi perlakuan diulang sebanyak empat kali sehingga terdapat 32 satuan percobaan. Variabel yang diamati yaitu kecepatan muncul tunas, jumlah tunas, jumlah daun, tinggi planlet dan warna kalus. Hasil penelitian menunjukkan bahwa komposisi ZPT 2 ppm BAP dan 0,2 ppm cenderung lebih mendukung pertumbuhan eksplan pucuk pada apel varietas Fuji walaupun tidak signifikan secara statistik. Media kultur yang disuplai 2 ppm BAP dan 0,2 ppm NAA cenderung lebih baik bagi pertumbuhan apel varietas Fuji pada kedua jenis eksplan yang ditunjukkan dengan pembentukan tunas dan daun yang relatif lebih banyak. Penggunaan eksplan pucuk lebih baik bagi pertumbuhan apel varietas Fuji dengan ditunjukkan pembentukan daun paling banyak serta jumlah maupun kecepatan muncul tunas yang cenderung lebih banyak dan lebih cepat.
