    Abstract:

    To evaluate the potential of Commelina benghalensis as a forage for ruminants, effects of plant maturity on chemical composition, rumen degradability as well as its increased dietary inclusion level on intake, digestibility and N balance in sheep fed Sorghum almum were investigated with forage obtained from the wild, re-established and harvested at 6, 10 and 14 weeks of growth. Composite herbage samples were analyzed for dry matter (DM), chemical components, total extractable phenolics (TEP) and amino acid content. In sacco rumen degradability measurements used six individually confined wethers (8 ± 0.5 months of age; 21 ± 2.6 kg live-weight (LW)) fitted with rumen cannulae and fed a ration of 3:1 fresh S. almum and Medicago sativa hay (about 1:2 on a DM basis). In sacco bags containing 5 g each of dry herbage were inserted into the rumen and withdrawn sequentially after 0, 12, 24, 36 and 48 h. Metabolizable energy (ME) was estimated from 24 h in vitro gas production. In the digestibility study, 12 wethers fitted with rumen canula were housed in metabolic crates and allotted to four treatment diets (i. e., D0, D10, D20 and D30) constituted from fresh S. almum and pre-wilted C. benghalensis in a randomized complete block design. The control diet (D0) was 3 kg fresh S. almum (≈535.5 g DM/wether/d about 30 g/kg LW), whereas D10, D20 and D30 were D0 +300, 600 or 900 g of wilted C. benghalensis (≈34, 68 or about 102 g DM/wether/d), respectively. The study lasted for 21 d. Dry matter, fibre and TEP content increased (P<0.001) with maturity of the forage, whereas those of CP and EE decreased (P<0.0001) over the same period. Amino acids (AA) also declined with maturity (P<0.05). Rumen degradability of DM and OM were unaffected, but DM intake increased linearly (P<0.0001) at a decreasing rate (Q: P<0.05) and DM digestibility (DMD) and N intake increased linearly (P<0.01 and P<0.0001, respectively) as level of C. benghalensis in the diet increased. Results indicate that advancing maturity affected chemical composition, but not rumen degradability, of C. benghalensis and also demonstrated that inclusion of C. benghalensis in S. almum diet improved intake, digestibility and N intake, suggesting its potential use as a feed supplement.

    Abstract:

    This study was conducted in Naivasha, Kenya over 84 days to examine effect of vetch (Vicia villosa), Commelina benghalensis and Lucerne (Medicago sativa) used as protein supplements on growth rate and feed intake of Dorper sheep wethers fed Sorghum almum. A total of 24 wethers (5 ± 0.32 months; 17.3 ± 2.58 kg BW) in a randomized complete block design were used (4 treatments, 6 wethers each). Treatments were: In control diet (D1), 4 kg fresh Sorghum almum (of about 158.8 g DM/kg) was fed as sole diet (≈ 635 g DM/wether/d), whereas diets D2, D3 and D4, daily ration comprised of S. almum (about 508 g DM/d) + 127 g DM/d pre-wilted C. benghalensis, vetch hay and Lucerne hay, respectively. The mean ADG of wethers in D1 was lower than those recorded by wethers in D2, D3 and D4 (P < 0.0001). The mean DM intake in D1 was also lower (P < 0.0001). Results indicate that C. benghalensis, vetch and Lucerne improved the overall performance of the wethers.

  • Glyphosate associated with other herbicides for control of Commelina benghalensis and Spermacoce latifolia
    Semina: Ciências Agrárias, 2011

    Abstract:

    The widespread cultivation of Roundup Ready soybeans enabled the use of glyphosate for post-emergence weed control in, turning weed handling into an easier and less costly operation. Despite such improvements, controlling glyphosate tolerant species can still be improved by associations with other herbicides. The aimed at evaluating the effect of the association of different herbicides with glyphosate in relation to Commelina benghalensis and Spermacoce latifolia control, after spraying plants in two different growth stages (1-3 and 4-6 leaves). For that, four experiments were carried out under greenhouse conditions, where glyphosate was applies at rates of 480 and 960 g a.e. ha -1 , isolated or combined in tank mixtures with cloransulam-methyl (30,24 g ha -1 ), chlorimuron-ethyl (12,5 g ha -1 ), imazethapyr (80 g ha -1 ), fomesafen (62,5 g ha -1 ), lactofen (72 g ha -1 ), flumiclorac-pentyl (30 g ha -1 ) and bentazon (480 g ha -1 ), besides a no-herbicide check. We evaluated the percentage of control at 3, 7, 14, 21, 28 and 35 days after application (DAA) and shoot dry mass (35 DAA). For C. benghalensis control, when herbicides were applied at 1-3 leaves stage, all treatments performed satisfactorily in weed control. For S. latifolia , the highest levels of weed control when applications were made at 4-6 leaves stage, when even glyphosate alone at lowest rate (480 g a.e. ha -1 ), provided excellent weed control. Overall, the use of tank mixtures improved weed control of both species when the rate of 480 g a.e. ha -1 of glyphosate was applied at earlier stages of weed development.

    Abstract:

    A liberacao da soja transgenica possibilitou o uso do glyphosate para o controle das plantas daninhas em pos-emergencia, facilitando o manejo e diminuindo os custos. No entanto, o controle de algumas especies tolerantes ao glyphosate pode ser otimizado com associacoes com outros herbicidas. O trabalho teve como objetivo verificar o efeito da associacao de diferentes herbicidas com glyphosate para o controle de Commelina benghalensis e Spermacoce latifolia apos aplicacao dos herbicidas em dois estadios de desenvolvimento (1-3 e 4-6 folhas). Para isso, foram realizados quatro experimentos em casa de vegetacao, aplicando-se glyphosate nas doses de 480 e 960 g ha-1, isolado ou combinado com os latifolicidas cloransulam-methyl (30,24 g ha-1), chlorimuron-ethyl (12,5 g ha-1), imazethapyr (80 g ha-1), fomesafen (62,5 g ha-1), lactofen (72 g ha-1), flumiclorac-pentyl (30 g ha-1) e bentazon (480 g ha-1), alem de uma testemunha sem herbicida. Foram realizadas avaliacoes de porcentagem de controle aos 3, 7, 14, 21, 28 e 35 dias apos aplicacao (DAA) e massa seca da parte aerea (35 DAA). Para o controle de C. benghalensis, quando a aplicacao e realizada no estadio de 1-3 folhas todos os tratamentos apresentaram controle satisfatorio. Para S. latifolia, as maiores eficiencias foram obtidas para as aplicacoes realizadas no estadio de 4-6 folhas, nas quais mesmo o glyphosate isolado na menor dose testada (480 g ha-1), proporcionou excelente controle. De modo geral, o uso de misturas melhorou o controle de ambas as especies quando se usa glyphosate a 480 g ha-1 em estadios mais precoces do desenvolvimento das plantas daninhas.
