Effects of fertilizer types and plant spacings on plant morphology, biomass yield and chemical com position of Brachiaria Hybrid Mulato II grass grown in lowlands of northwest Ethiopia2020 •
This experiment was conducted to evaluate the effects of fertilizer types and plant spacings on plant morphology, biomass yield and chemical composition of brachiaria hybrid mulato II grass grown using irrigation in lowlands of northwest Ethiopia. The experimental design used was a 3×3 factorial layout in a randomized complete block design with three replications giving a total of 27 plots, each measuring 2×2 m2. The plant spacings were 15, 30 and 45cm between plants and fertilizer types were commercial fertilizer (NPS), cattle manure and control (without fertilizer). Morphological parameters such as plant height (PH), leaf length per plant (LLPP), number of leaves per plant (NLPP), number of tillers per plant (NTPP), leaf to stem ratio( LSR), number of roots per plant (NRPP),root length per plant (RLPP), root circumference(RC), leaf area index (LAI), biomass yield and chemical composition were collected. All the data were subjected to GLM ANOVA following the procedures of SAS. Most...
In ruminant-forage systems herbage allowance (HAL) has a major impact on grazing intensity and sward structure, affecting animals, plants, and ultimately, pasture yield. Data on HAL responses of tropical cultivated pastures are scarce and this information may be useful in optimizing pasture utilization. The objective of this study was to describe and contrast sward structure and herbage accumulation responses of 'Marandu' palisadegrass [Brachiaria brizantha (A.Rich.) Stapf] pastures to HAL during two grazing seasons (warm-rainy season of 2003 and 2004). Treatments were four daily HAL levels, 5, 10, 15 and 20 kg herbage mass per 100 kg live weight (%) in a rotational stocking system with 35 days of grazing cycle (28-day rest; 7-d grazing). Post-graze swards were shorter (~17 cm) under 5% HAL. For the other HAL levels, postgraze sward height increased throughout the experiment (21 to 50 cm). Changes in sward light interception (LI) were highly associated with height, but differed across HALs in 2004. Early in the 2003 season, HAL increases resulted in linear increase of the daily herbage accumulation rate (HAR; 47, 66, 78, and 98 kg DM ha-1 d-1 for 5, 10, 15 and 20%-HAL, respectively). For the subsequent grazing cycles of 2003 and all through 2004, HAR decreased with increasing HAL. This was associated with the excessive increase in sward height and mean forage mass, caused by lower grazing intensity. The use of lax (high) HAL to maximize animal performance, especially 10, 15 and 20%-HAL, resulted in decreased pasture performance (lower herbage accumulation, HAC) in palisadegrass pastures. ESTRUTURA DO DOSSEL E PRODUÇÃO DE FORRAGEM EM PASTAGENS DE CAPIM MARANDU [Brachiaria brizantha (A.Rich.) Stapf] SOB LOTAÇÃO ROTACIONADA EM RESPOSTA À OFERTA DE FORRAGEM RESUMO: A oferta de forragem (OF) aos animais em pastejo causa forte impacto na intensidade de desfolhação e conseqüentemente na estrutura do dossel, influindo indiretamente no acúmulo de forragem. O objetivo deste estudo foi avaliar estrutura do dossel e acúmulo de forragem em pastagens de capim-Marandu em resposta à OF. Os tratamentos foram quatro OFs, 5, 10, 15 e 20 kg massa de forragem por 100 kg peso vivo por dia (%), em ciclos de pastejo de 35 dias (28 d de descanso e 7 d de ocupação). A altura do dossel no pós-pastejo foi mais baixa para a OF 5%, que se manteve em torno de 17 cm, enquanto que para as demais houve aumento progressivo dos valores ao longo do experimento (21 a 50 cm). A variação na interceptação de luz (IL) em função da altura do dossel foi significativa, e em 2004 diferiu entre OFs. Inicialmente o aumento da OF resultou em aumento linear da taxa diária de acúmulo de forragem (TAF), com 47, 66, 78 e 98 kg forragem ha-1 (ciclo I – 2003), nas pastagens sob OF 5, 10, 15 e 20%, respectivamente. Entretanto, nas rebrotações posteriores houve diminuição acentuada da TAF para OFs mais elevadas, condição que persistiu no segundo ano do experimento (2004), e foi associada ao excessivo aumento da altura do dossel e da massa de forragem, como conseqüência da diminuição da intensidade de pastejo. A utilização de OFs generosas com intuito de elevar o desempenho animal, trouxe conseqüências negativas sobre o acúmulo de forragem em pastagens de capim Marandu. Palavras-chave: acúmulo de forragem, altura do dossel, interceptação de luz, massa de forragem Braga et al.

A study was conducted to evaluate the effects of plant spacing and N fertilizer application on chemical composition of Brachiaria hybrid cv. Mulato II grass for the first 150 days after planting. A factorial experiment with 3 urea fertilizer levels (0, 50 and 100 kg/ha) and 4 spacings between plants and rows (20 x 20, 30 x 40, 40 x 60 and 50 x 80 cm) with 3 replications was used. Chemical analyses were conducted for crude protein (CP), ash, neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL). Results indicated that DMY, CP%, CPY, NDF% and ADF% were significantly (P<0.05) affected by plant spacing and fertilizer levels interactions. However, ash and ADL were significant (P<0.05) affected by only main effects. The highest CP% was recorded for wider plant spacing (50 x 80 cm) with higher urea fertilizer level (100 kg/ha) (S4F3) Similar studies need to be conducted over much longer periods to determine to what extent these findings relate to performance over the life of a permanent pasture.
