  • Rubber Plantation: Soil Management & Nutritional Requirement
    2013
    Co-Authors: Wan Noordin Daud
    Abstract:

    Rubber has been grown commercially in Malaysia since 1903, when the first rubber estate was established in Melaka. Since then, several usage of rubber have been discovered from time to time. Suitable planting area has decreased and to overcome this problem planting of rubber gets into marginal and problem soils. This books describing soil genesis, management and Nutritional Requirement of rubber on these marginal soils are scarce. This book is written in 10 chapters, covering various aspects of soil management and Nutritional Requirement with latest information on current technology available in the rubber industry. These include soil series identification, and fertilizer recommendations for sustainable rubber plantation.

  • Methodology in the study of seabass (Lates calcarifer Bloch): Nutritional Requirements in Singapore
    Journal of Applied Ichthyology, 1995
    Co-Authors: H. B. Lee, J. Guillaume, R. Chou, G. Cuzon, H. H. Heng, J. Fuchs
    Abstract:

    This paper describes the effort of the Marine Aquaculture Section of the Primary Production Department in Singapore and the Institut Francais de Recherche pour l'Exploitation de la Mer in developing adequate facilities for fish Nutritional Requirement studies in Singapore, and in introducing appropriate Nutritional methodology so that results are reliable and accurate. One of the first achievements was the demonstration of homogeneous fish (tropical seabass, Lates calcarifer Bloch) growth response in a newly established tank system before any Nutritional experiments were initiated. The application of statistical procedures that take into consideration the power of a test and number of replications required has allowed for more accurate interpretation of results. This can be seen in the results of the first Nutritional Requirement experiment on the optimal dietary protein level of the seabass at constant energy.

  • methods for simulating Nutritional Requirement and response studies with all organisms to increase research efficiency
    British Journal of Nutrition, 2017
    Co-Authors: Dmitry V Vedenov, R A Alhotan, Runlian Wang, G M Pesti
    Abstract:

    Nutritional Requirements and responses of all organisms are estimated using various models representing the response to different dietary levels of the nutrient in question. To help nutritionists design experiments for estimating responses and Requirements, we developed a simulation workbook using Microsoft Excel. The objective of the present study was to demonstrate the influence of different numbers of nutrient levels, ranges of nutrient levels and replications per nutrient level on the estimates of Requirements based on common Nutritional response models. The user provides estimates of the shape of the response curve, Requirements and other parameters and observation to observation variation. The Excel workbook then produces 1-1000 randomly simulated responses based on the given response curve and estimates the standard errors of the Requirement (and other parameters) from different models as an indication of the expected power of the experiment. Interpretations are based on the assumption that the smaller the standard error of the Requirement, the more powerful the experiment. The user can see the potential effects of using one or more subjects, different nutrient levels, etc., on the expected outcome of future experiments. From a theoretical perspective, each organism should have some enzyme-catalysed reaction whose rate is limited by the availability of some limiting nutrient. The response to the limiting nutrient should therefore be similar to enzyme kinetics. In conclusion, the workbook eliminates some of the guesswork involved in designing experiments and determining the minimum number of subjects needed to achieve desired outcomes.

  • Nutritional Requirement of Sugarcane Cultivars
    Journal of Agricultural Science, 2018
    Co-Authors: Vinicius Santos Gomes Da Silva, Mauro Wagner De Oliveira, Vilma Marques Ferreira, Terezinha Bezerra Albino Oliveira, Elaine Rocha Galvão, Aleksandro Ferreira Da Silva, Polyana Albino Silva Machado
    Abstract:

    Sugarcane produces a large amount of biomass, extracts and accumulates high amounts of nutrients. In the literature the Nutritional Requirements for most cultivated varieties in the past are found, however there is little information on the new varieties currently planted. The objective of this study was to evaluate the Nutritional Requirement of four sugarcane varieties, currently very planted, in the cycles of plant-cane, first and second ratoon. The study was installed in a Yellow Oxisol. The experimental design was a randomized block design, with five replications, and four treatments: RB867515, RB92579, SP813250 and VAT90212. During maturation of the cane, in the three evaluation cycles, the productivity of natural biomass and the Nutritional Requirement of macronutrients of the varieties were determined. It was evidenced that the cultivars of sugarcane are of high productive potential and resemble the accumulation of biomass, observing a yield of 158, 128 and 107 t ha-1 in the cycles of plant-cane, first and second ratoon. Regarding the Nutritional Requirement, the varieties did not differ among them and expressed the following order of need in the plant-cane K > N > Ca > Mg > S > P, in the first and second ratoon, the sequence observed was K > N > Ca > S > Mg > P.
