  • Mineral Nutrition of Abaca (Musa textilis Née) Planted under Coconut and Rainforestation Production Systems
    Annals of Tropical Research, 2016
    Co-Authors: Marlito Bande, Victor Asio, Joachim Sauerborn, Volker Römheld
    Abstract:

    The allocation of nutrients within the Abaca plant is of interest, as it determines the amounts which may be removed from the farm, returned to the soil in dead plant part, and available for re-translocation to subsequent generations of suckers. Hence, the study was conducted to investigate the level of nutrition among Abaca plants grown under diversified multi-strata agroecosystems and to understand the pattern of Abaca nutrient uptake planted under coconut and Rainforestation production systems. The allocation of nutrients within the Abaca plant is of interest, as it determines the amounts which may be removed from the farm, returned to the soil in dead plant part, and available for re-translocation to subsequent generations of suckers. Hence, the study was conducted to investigate the level of nutrition among Abaca plants grown under diversified multi-strata agroecosystems and to understand the pattern of Abaca nutrient uptake planted under coconut and Rainforestation production systems. In the Abaca–coconut agroecosystem, results show that availability of macronutrients from different blocks demonstrates a high degree of significant differences (p≤0.01) within 0-30cm soil depth. These differences can be attributed to the history of land uses, farmer’s management practice and soil the type. On the other hand, it can be concluded that the trees planted under the Rainforestation system plays a significant role in the nutrient fluxes and the improvement of soil acidity. This is due to the fact that trees function as “nutrient-pumps”. Therefore, integrating Abaca under the Rainforestation system is a best option. Finally, it is not enough and safe to conclude that the low nutrient concentration in Abaca leaves is due to low nutrient in the soil concentration solution since the standard values for Abaca is still unknown. Thus, using the results for diagnosing nutrient deficiencies is insufficient.

  • Growth Performance of Abaca (Musa textilis Née) Integrated in Multi-strata Agroecosystems
    Annals of Tropical Research, 2016
    Co-Authors: Marlito Bande, Victor Asio, Joachim Sauerborn, Volker Römheld
    Abstract:

    Abaca is a shade loving crop with a good potential to be integrated into agroforestry systems that offer sources of income and prevent soil erosion. However, in integrating Abaca into multi-strata agroecosystems, one has to consider radiation interception and the efficiency with which radiation energy is used to produce photosynthates since play a crucial role in the growth of these tree-crop stands. Hence, this study investigate the best shade plant-Abaca d combination and its influence on light transmission ratio in relation to the Abaca’s morphological growth performance. The results revealed that the light intensity under the canopy shade of coconuts is sufficient for the growth of Abaca plants. On the other hand, Rainforestation (the planting of native tree species to rehabilitate degraded lands) appeared to be an effective approach in restoring the functions of an Abaca-based agroecosystem by improving soil quality suitable for the crop. Therefore, the tree-Abaca under the Rainforestation system was the best combination. However, the sustainability of both production system always lies s on the hands of the farmers, either to cut or harvest the trees or old coconut palms for lumber or to preserve them for ecological purposes by providing shade and wind breaks for the Abaca plants. Finally, due to high planting density in both types of Abaca-based agroecosystems, fertilizer application and the use of high quality planting materials are highly recommended. Likewise, topography and exposure to strong winds should be considered during site selection prior to Abaca-based production system development.

  • fiber yield and quality of Abaca musa textilis var laylay grown under different shade conditions water and nutrient management
    Industrial Crops and Products, 2013
    Co-Authors: Victor Asio, Marlito M. Bande, Jan Grenz, Joachim Sauerborn
    Abstract:

    Abstract The knowledge gap on the optimum light, nutrient and water requirements of Abaca to attain optimum yield and limited information on how these parameters affect fiber recovery and fiber quality under field conditions are very important for Abaca production and management. Light infiltration was reduced by 30%, 40%, and 50% of full sunlight using polypropylene shade nets. Irrigation was applied at a rate of 5 l plant −1  application −1  day −1 . Placement application of N, P 2 O 5 , K 2 O using complete fertilizer was done at 14 g plant −1  quarter −1 for the first six months and was increased to 40 g plant −1  quarter −1 for the next six months after planting. Results showed that Abaca planted under different light regimes showed that 50% shade had significantly ( p p Laylay ) to achieve an optimum machine stripped fiber yield of 135.04 ± 4.31 g plant −1 without affecting fiber quality for industrial purposes.
