FORAGE PRODUCTION AND NUTRITIVE VALUE OF (Clitoria ternatea) HARVESTED AT 60, 75 AND 90 DAYS AFTER PLANTING

Abstract

ABSTRAKPenelitian dilaksanakan dengan tujuan untuk mengkaji produksi dan nilai nutrisi C. ternatea yang dipanen pada umur 60, 75 dan 90 hari setelah panen. C. ternatea ditanam pada 18 petak dengan ukuran 3 × 3 m2 dengan jarak tanam 40 × 20 cm dengan 3-4 biji per lubang tanam. Hijauan dipanen pada umur 60, 75 dan 90 hari setelah tanam sebagai perlakuan dengan masing-masing 6 ulangan. Variabel yang diukur adalah produksi hijauan, komposisi kimia hijauan dan kecernaan in vitro bahan kering dan bahan organik. Hasil penelitian menunjukkan bahwa tidak ada perbedaan signifikan (P>0,05) produksi hijauan C.ternatea yang dipanen pada umur 60, 75 dan 90 hari setelah tanam. Sementara itu, rasio daun:batang menurun (P<0,05) dengan meningkatnya umur tanaman. Kandungan protein hijauan yang dipanen pada umur yang berbeda tidak nyata antara umur panen tetapi nilai energi yang ditunjukkan oleh kecernaan in vitro bahan organik lebih tinggi pada hijauan yang dipanen pada 60 hari dibandingkan dengan 75 dan 90 hari setelah tanam. Dengan demikian dapat disimpulkan bahwa waktu terbaik untuk memanen C. ternatea untuk digunakan sebagai pakan suplemen pedet adalah pada umur 60 hari setelah tanam. Kata kunci: Clitoria ternatea, kecernaan bahan organik in vitro, energi, supplemen pedet ABSTRACTThe purpose of this experiment was to investigate herbage production and nutritive value of C. ternatea harvested at 60, 75 and 90 days after planting. The legume was planted in eighteen of 3 × 3 m 2 plots a t 4 0 × 2 0 c m 2 . Forage was harvested at 60, 75 and 90 days after planting as treatmens. Variables measured included forage production, nutrient content and in vitro dry matter and organic matter digestibility. Herbage production was not significantly different (P>0.05) when harvested at different stages of growth. Leaf : stem ratio, however, declined (P<0.05) with advancing growth stage. Forage quality in terms of crude protein content was comparable (P>0.05) among different harvest time. Meanwhile the energetic value as shown by in vitro organic matter digestibility (IVOMD) was significantly higher (P<0.05) when C. ternatea was harvested 60 days compared to 75 and 90 days after planting. It can be concluded that for calf supplement, C. ternatea is preferably harvested at 60 d after planting.

Effect of Types and Dosages of Foliar Fertilizers on Morphology and Production of Clitoria ternatea

“…Dry matter production obtained from the treatment ranged from 14,73-16,75 tons/ha. The results obtained are higher than that of (Jelantik et al 2019) that dry matter production of Clitoria ternatea ranged from 5,18-7.81 tons/ha, but lower than that of (Sutedi 2013) where the dry matter production was 25-38 tons DM/ha. The dry matter production which was relatively the same in all treatments at the dose levels of foliar fertilizer was probably because the levels of N content in the liquid fertilizer was not too high so that the requirement of butterfly pea for N elements was not fulfilled.…”

Optimasi Level Benzyl Amino Purin (BAP) terhadap Pertumbuhan Tanaman Kembang Telang (Clitoria ternatea) melalui Teknik Kultur Jaringan

“…Sutedi (2013), bahwa beberapa keunggulan kembang telang meliputi, protein kasar daun (18% -25%), protein kasar batang dan daun (9% -15%), nilai kecernaan bahan kering (70%), kecernaan bahan organik (69,7%), energi kasar (18,6 MJ kg -1 ), kecernaan energi tanaman (66,6%), energi termetabolis (12,4 MJ kg -1 ), lemak kasar (10%) dan gula pada biji (5%). Potensi produksi kembang telang pada fase awal generatif, yakni umur 60-75 HST (Hari Setelah Tanam) adalah 6,05 ton BK ha -1 (Jelantik et al 2019).…”

Nutrient content and in vitro digestibility of rejected red seaweed (Eucheuma cottonii) from different origin

“…Utilisation of certain legumes such as Clitoria ternatea in the complete feed had been conducted to substitute concentrate. Clitoria ternatea forage harvested at vegetative stage contained crude protein of 16 to 18%, gross energy of 18.6 MJ/kg, organic matter digestion of 69.7%, and metabolic energy in ruminant animal of 12.4 MJ/kg (Jelantik et al, 2015). However, the availability of the legume during dry season was limited so there was need for other high-quality feed which its availability during dry season.…”
