Pengelolaan Unsur Hara Terpadu Dalam Budidaya Tanaman Porang (Review)

Abstract

Elephant food yam (Amorphophallus muelleri Blume) is an important tuber plant that is grown in most of the tropical countries including Indonesia and is a very profitable export commodity. Soil nutrients availability is one of the most important factors that determine the production of elephant food yam plants. However, there is no single nutrient source, either from inorganic fertilizers or organic fertilizers or biological fertilizers, which is able to meet all the nutrient needs of the plants grown. Therefore, integrated nutrient management (INM) of elephant food yam plants seems to be a way out to maintain sustainable production and increase profitability. This paper reviews the results of research on various issues of INM-based production management for elephant food yam plants and analyzes the extent of research on the use of INM both in Indonesia and abroad. The benefits of integrated nutrient management are well documented for vegetable crops. However, it is still very little available for elephant food yam plants, especially in Indonesia. Integrated nutrient management (INM) is a very important technological innovation to be applied to elephant food yam cultivation. Elephant food yam is a high nutrient consumeplant, so a wise and precise combination of inorganic and organic fertilizers as well as bio-fertilizer will result in sustainable and sinergistic use of soil nutrients of elephant foot yams. Therefore, recommendations for research need for INM of elephant food yam should be carried out in order to increase the production of it in a sustainable manner.

The effect of planting material and organic fertilizer on growth of elephant foot yam (Amorphophallus oncophyllus Prain.)

“…Phosphorus stimulates the growth of roots and young plants, while root crops absorb a lot of element K, because it is associated with the need for carbohydrate accumulation. Potassium helps increase the carbohydrate content significantly which in turn helps increase tuber size [10]. The quantity and quality of elephant foot yam production can be increased by giving potassium.…”

A Literature Review of Artocarpus lacucha Focusing on the Phytochemical Constituents and Pharmacological Properties of the Plant

“…If the soil elements are unavailable, plant growth will be hampered and production will decrease. Plants’ requirements for nutrients already exist in the soil but their availability is sometimes insufficient to meet plants’ needs [ 19 , 24 ].…”

Optimizing the Growth of Porang Plants (Amorphophalus Muelleri) using a Combination of Market Waste Compost and Growmore Fertilizer

“…Tidak dipengaruhinya jumlah tangkai anak daun pada penelitian ini, diduga dikarenakan ketersediaan zat hara yang tidak dapat dimanfaatkan secara optimal oleh tanaman porang. Tanaman memerlukan zat hara untuk pertumbuhan vegetatif terutama nitrogen dan kalium secara seimbang untuk merangsang pertumbuhan vegetatif tanaman, sesuai dengan kebutuhan metabolisme tanaman tersebut (Rustiana et al, 2021). Menurut penelitian yang dilakukan oleh Sulistio et al, (2018), pemberian pupuk growmore tidak memberikan perbedaan nyata terhadap umur berbunga, umur panen dan jumlah per tanaman pada tanaman cabai, beberapa alasan tidak maksimalnya pemberian pupuk growmore dikarenakan kondisi tanah yang memiliki pH sangat rendah sehingga unsur hara P tidak dapat diserap oleh tanaman karena terikat unsur Al tanah dan memengaruhi kesuburan tanaman.…”
