Abstract
<p class="16">The aim of this study was to determine effect of types and dose levels of foliar fertilizers on morphology and production of <em>Clitoria ternatea</em>. This study was conducted from September to November 2020 at Forage Research Garden for Animal Feed and Pasture, Faculty of Animal Science, Gadjah Mada University, Yogyakarta. Materials used were <em>Clitoria ternatea</em>, liquid organic fertilizer of rabbit and gandasil D fertilizer. This study was designed in a Completely Randomized Design (CRD) with factorial pattern of 2x4. The fertilizer dosages were: 0,1.5,3.0 and 4.5 g/l/plot. The parameters measured were plant height, stem diameter, leaf area, number of branches, fresh and dry matter productions. Data were analyzed by the analysis of variance at 5%, with Duncan's Multiple Range Test (DMRT). Results showed that types of foliar fertilizers did not affect morphological characteristics and production of<em> Clitoria ternatea</em> (P&gt;0.05), but the fertilizer dosages had significant effect (P&lt;0.05) on morphological characteristics except for leaf area and production of <em>Clitoria ternatea</em>. The higher the dose level of foliar fertilizer the greater the plant height, stem diameter and number of branches. Dosage of 4.5 g/l/plot resulted in the highest plant height, stem diameter and number of branches each 160.02, 1.14 cm and 18.96 branches, respectively. Dosage of4.5 g/l/plot gave the highest fresh and dry matter production of 19.22 and 16.75 tons/ha. It is concluded that increasing the dosage level of foliar fertilizer up to 4.5 g/l/plot resulted in an increased quantity measures of several morphological characteristics and production.</p>
Highlights
Main source of feed for ruminants is forage such as grass, legumes and agricultural or plantation wastes (Saking & Qomariyah 2017)
Result showed that the application of different types of foliar fertilizers did not have a significant effect on morphology and production of butterfly pea (Clitoria ternatea) (P>0.05), but the fertilizer dose level did affect significantly (P
The plant height of the butterfly pea plant was obtained according to research by (Gomez & Kalamani 2003) who reported that the plant height of Clitoria ternatea could reach 90 – 162 cm and was smaller than that of Arnawa et al (2017) where the height of the butterfly pea ranges from 178,75 – 220 cm
Summary
Main source of feed for ruminants is forage such as grass, legumes and agricultural or plantation wastes (Saking & Qomariyah 2017). The main obstacle in providing forage for livestock is its production which is not available throughout the year. This is because the availability of forage is highly dependent on the season. Indonesia has two seasons: rainy season and dry season. Production of animal feed will be abundant, on the otherhand during the dry season the production will decrease. Most farmers in Indonesia obtain forage from their own gardens, rice fields, roadsides, forest edges and agricultural residues. Forage obtained from intensive planting/cultivation is very limited, in line with the reduction in agricultural or productive land. Productive and fertile land is usually used to grow food crops that have economic value
