Effect of Organic and Inorganic Fertilizers on Yield and Quality of Synedrella nodiflora (Tropical Weed)

Abstract

This study aimed to determine the effect of organic and inorganic fertilizers on the cultivation of tropical weed Synedrella nodiflora as forage. The study was conducted from May to July 2018. The treatments of the research were control (C), organic fertilizer (D) and organic fertilizer + urea (DU), with 3 replications that were arranged on experimental design with a completely randomized design, in a unidirectional pattern and continued with least significant different (LSD). Organic fertilizer dosage in this study was 5 tons/ha, while urea fertilizer was 350 kg/ha, with plant spacing was 45x60 cm. The observed parameters were plant height, forage production and chemical composition (5 weeks after planting). Plant height of C, D and DU were 41.59, 47,42, and 50.59 cm respectively. Forage production of dry matter after 5 weeks planting at C, D and DU were 1.69, 1.70 and 2.91ton/ha, with in vitro digestibility values ranging from 51.68 to 57.70% (IVDMD) and 51.71 to 61.98% (OMD) respectively. The chemical composition of native S. Nodiflora were 12.32% of dry matter (DM), 62.45% TDN count for cattle and 67.42% TDN count for sheep. Based on DM, The organic matter was 84.46%, crude protein 20,11%, crude fiber 13.26%, extract ether 7.77%, and nitrogen free extract 37.08%. The combination of organic fertilizer and urea increased the height and fresh and dry matter production S. nodiflora.

Forage Pellets Quality From Weed Legetan With Different Composition

“…Ingredients used in this study were rice bran, and Legetan that harvested from the pasture land of Forage Forage and Pasture Science Laboratory. dry matter (DM), 23% CP and 30% crude fiber (CF) [5], rice bran contains DM 89.2% DM, ash 13.8%, 8.6% CP, 10.8% ether extract (EE), CF 21.6%, and 45.33% nitrogen free extract (NFE) [7]. There were two (2) compositions of forage pellets, namely: A = 90% Legetan and 10% rice bran B = 80% Legetan and 20% rice bran…”

“…People is looking for solution to maintain feed suplly in both season by feed technology processing [3]. Another side, Indonesia has abundant potential type of forage sources that can be used as feed for ruminant diet, weeds Legetan (Synedrella nodiflora) is one of it [4] [5].…”

“…There still open large opportunity to do research related to forage pellets with Legetanbased. Therefore, needs to be conducting research activities with scooping about weeds for feed [5].…”

“…Incorporating high fiber such as paragis leaves into snack items may, therefore help achieve the recommended dietary fiber intake of these picky children. Paragis grass can contribute to about 21.57% to 29.17% of crude fiber (Garcia et al, 2003;Morah & Otuk, 2015;Suwignyo et al, 2017), to as high as 64% as reported by Jackson et al (1996), with digestibility coefficient of 69.6 (Regmi et al, 2004). Furthermore, macro and microminerals were reported present in paragis grass (Serra et al, 1997;Gbadamosi, 2012); among which are Co, Cu, Fe, Ca, K, Mg, Na, P. But incorporating grass in foods expectedly could impart undesirable taste and aftertaste in the product.…”
