The Influence of Some Type of Manure on The Growth and Production of Elephant Grass (Pennisetum purpureum) CV. Taiwan in Acid Soil

Abstract

This study aims to determine the effect of some types of manure on growth and production of elephant grass (Pennisetum purpureum) cv. Taiwan. The expected results of this research can determine which is the type of manure suitable for the area of the former coal mines that have acid soils (marginal lands). This research using Complete Random Design with four treatments and six replications. The treatment is different source of manure which is control, cow manure, goat manure, and chicken manure. The parameters observed were plant growth including plant height, leaf width, leaf length, fresh weight production, and dry weight production. This study uses the acid soils of the former coal mine with a pH of 4.2 which is input into the polybags, seedlings of elephant grass (Pennisetum purpureum) cv Taiwan in the form of cuttings, Cow, goat and chicken dung are used as a source of manure. This research was conducted in the green house for 60 days. The results of the research obtained the data for plant height (cm) the highest Goat Manure (P2) 229.85; leaf Length (cm) the highest Goat Manure (P2) 113.10: Leaf width (cm) the highest Goat Manure (P2) 5.50; Production of Fresh Weight (gr/polybag) the highest Goat Manure (P2) 1361.67; the Production of Dry Weight (gr/polybag) the highest Goat Manure (P2) 214.28. The conclude that the manure suitable for the area of the former coal mines that have acid soils (critical area) is the manure from goat because it produces the highest growth and production than others.

Mycorrhizal inoculation and application of chicken manure to increase sweet potato production in acidic soil

“…In addition, inoculation of arbuscular mycorrhizal fungi capable of symbiosis with various types of plants is an alternative action in the management of acid soils. Arbuscular mycorrhizal fungi play a role in reducing Al stress in plants through exudation of organic acids and chelating ability, and increase nutrient uptake to meet cropping needs [6]. The percentage of roots infected with mycorrhizae is shown to be a parameter of the degree of mycorrhizal infection which is an indicator of the ability of mycorrhizae to infect the roots of plants.…”

PENGGUNAAN BERBAGAI KOMPOS KOTORAN TERNAK TERHADAP PERTUMBUHAN Pennisetum purpureum cv. Pakchong

“…Penggunaan pupuk kotoran ternak (sapi, kambing dan ayam) menghasilkan tinggi tanaman Pennisetum purpureum cv. Taiwan yang lebih tinggi dibandingkan tanpa pupuk pada tanah yang masam (Sari et al, 2021). Rumput Pakchong 1 mempunyai tinggi tanaman dan jumlah anakan yang signifikan serta lingkar basal yang lebih besar yang menandai bahwa rumput gajah Pakchong 1 merupakan kultivar yang kuat dibandingkan kultivar rumput gajah lainnya, CO-3 dan Giant Napier (Wangchuk et al, 2015).…”

“…Penggunaan kompos kotoran ayam dan sapi berbeda nyata (P<0,05) lebih tinggi menghasilkan jumlah tunas dan jumlah daun rumput gajah cv. Pakchong dibandingkan (Sari et al, 2021). Pemberian pupuk kandang yang mengandung unsur hara makro dan mikro yang lengkap sudah bisa mencukupi kebutuhan pertumbuhan dari rumput raja.…”
