“…Cassava is well adapted to hot tropical climate with optimum growth reportedly occurring at 25-29°C and requiring a high temperature (35°C) and high solar radiation (1800 lmol m -2 s -1 ) for optimal leaf development and maximal photosynthesis (Alves 2002). Storage root yield and total biomass are positively correlated with the rate of leaf photosynthesis (Alves 2002).…”

“…Storage root yield and total biomass are positively correlated with the rate of leaf photosynthesis (Alves 2002). Cassava is also drought tolerant (Alves 2002). Thus, production of cassava may replace maize on the hotter and drier north coast and in the longer term replace rice on the south coast if rice fails to thrive.…”

The climate in Timor Leste (East Timor) is predicted to become about 1.5°C warmer and about 10 % wetter on average by 2050. By the same year, the population is expected to triple from 1 to 2.5-3 million. This article maps the predicted changes in temperature and rainfall and reviews the implications of climate change and population growth on agricultural systems. Improved cultivars of maize, rice, cassava, sweet potato and peanuts with high yield performance have been introduced, but these will need to be augmented in the future with better adapted cultivars and new crops, such as food and fodder legumes and new management practices. The requirements for fertilizers to boost yields and terracing and/or contour hedgerows to prevent soil erosion of steeply sloping terrain are discussed. Contour hedges can also be used for fodder for improved animal production to provide protein to reduce malnutrition.

“…Las hojas de este vegetal están compuestas por una lámina foliar palmeada profundamente lobulada y el peciolo. El número de hojas emitidas por la planta, su longevidad y características fotosintéticas son características específicas de cada variedad e influenciadas por aspectos ambientales de crecimiento (ALVES, 2002;OSPINA y CEBALLOS, 2002).…”

“…Esto permite considerar dicho producto como cultivo de relevancia en diversos países, principalmente de regiones tropicales (ALVES, 2002). La arquitectura del dosel (disposición de tallo, ramas y hojas) en esta planta, es un aspecto relevante; que permite conocer el impacto que ejerce la disposición del follaje sobre el proceso intercepción de la radiación incidente; asimismo, su efecto sobre la dinámica en la distribución de fotoasimilados, bajo condiciones de adecuada humedad de suelo tiene un papel crucial en el crecimiento y desarrollo de la planta (FAGERIA et al, 2006;AHUJA et al, 2008).…”

The objective of the research was evaluated the influence of soil availability on the architecture of cassava canopy. The work was carried out in the tropical dry forest area of the state of Sucre, Colombia. Experimental plots were established in October 2015, records of plant height, number of branches, foliar insertion angle and branching at twelve months of age, low experimental design in randomized complete blocks, with factorial arrangement . As fixed factors the cassava variety (MCOL 2066, CM 4919-1, SM 1411 and SM 2775) and irrigation (complementary irrigation and without complementary irrigation) were produced. Foliar insertion patterns favored by the absence of irrigation were found, being these of type plagiófilos in the superior third and planificadores in the middle and inferior thirds, what allows greater efficiency in the capture of the radiation. The height of the plant was influenced by the water supply, evidencing the superior growth around 17.9% under the use of a sheet of 17 millimeters of irrigation during the first months of the crop growth. The irrigation factor promotes in a differentiated way the architectural response of the canopy. Keywords:Genotypes; Insertion angle; variety; branching. ResumenEl objetivo de la investigación fue evaluar la influencia de la disponibilidad hídrica del suelo sobre la arquitectura del dosel de yuca. El trabajo se realizó en la zona de bosque seco tropical del departamento de Sucre, Colombia. Las parcelas experimentales se establecieron en octubre de 2015, registrándose datos de altura de planta, cantidad de ramificaciones, ángulo de inserción foliar y de ramificación a los doce meses de edad, bajo un diseño experimental en bloques completos al azar, con arreglo factorial. Como factores fijos se tuvo la variedad de yuca (MCOL 2066, CM 4919-1, SM 1411 y SM 2775) y el riego (riego complementario y sin riego complementario). Se encontraron patrones de inserción foliar favorecidos por la ausencia de riego, siendo estos de tipo plagiófilos en el tercio superior y planófilos en los tercios medio e inferior, lo que permite mayor eficiencia en la captura de la radiación. La altura de planta fue influenciada por la oferta hídrica, evidenciando superior crecimiento en alrededor de 17,9% bajo la aplicación de una lámina de 17 mm de riego durante los primeros meses de crecimiento del cultivo. El factor riego promueve de forma diferenciada la respuesta arquitectónica del dosel.

Cassava ( Manihot esculenta ) is the world's seventh most important crop in terms of production and provides the staple food for more than 500 million people in the humid tropics. Owing to its ability to survive adverse environmental conditions and its high efficiency at fixing CO 2 into carbohydrate compared with other crops, cassava has a vital role to play in a planet faced with the interrelated challenges of population growth, food scarcity, fuel shortage and climate change. Despite these advantages, cassava storage roots are nutritionally deficient, cyanogenic, deteriorate rapidly on harvest and the crop is prone to pests and diseases. However, through exploiting germplasm diversity, breeding and biotechnology many of these challenges can be addressed for the benefit of producers, processers and consumers. Key Concepts: Cassava storage roots are the staple food of hundreds of millions in the humid tropics. Owing to its drought tolerance and ability to grow on impoverished soils cassava is a vitally important famine reserve crop in sub‐Saharan Africa. Breeding and biotechnology can address the current limitations of cassava in order to make it a more productive, versatile and nutritious crop. Enhanced germplasm combined with improved agronomic practice can enable cassava to make a significant contribution to global food security. In addition to food, cassava is processed into industrial products and is of increasing interest for biofuel production.
