Unveiling constraints to cassava production in Cambodia: An analysis from farmers’ yield variations
Cassava (Manihot esculenta Crantz) is currently the most important upland crop of Cambodia, but information on yield variations and causal factors which is important for efficiently targeting efforts to increase production is still lacking. The objectives of this study were to determine the yield variations and causal factors for cassava production in Kampong Cham province in Cambodia. Fort...
متن کاملNutrient balances for cassava cultivation in Kampong Cham province in Northeast Cambodia
In Cambodia, cassava is mostly grown with little or no fertilizer inputs, but the magnitudes of nutrient balances are not known. This study was conducted to assess nutrient balances for cassava cultivation in Kampong Cham province in Northeast Cambodia. Forty five households in four cassava production zones were interviewed in relation to their cultural practices and crop residue management...
متن کاملFarmers' Perceptions on Early Storage Root Bulking in Cassava (Manihot esculenta Crantz) in East and Central Uganda and their Implication for Cassava Breeding
Early storage root bulking (ESRB) in cassava has increasingly become important in the national cassava breeding programmes in Africa. To assess farmers' perceptions on ESRB in cassava and identify their cultivar selection criteria, a study was conducted in east and central Uganda. One hundred and twenty cassava farmers were sampled and interviewed following structured questionnaires, and their ...
متن کاملPhenotypic approaches to drought in cassava: review
Cassava is an important crop in Africa, Asia, Latin America, and the Caribbean. Cassava can be produced adequately in drought conditions making it the ideal food security crop in marginal environments. Although cassava can tolerate drought stress, it can be genetically improved to enhance productivity in such environments. Drought adaptation studies in over three decades in cassava have identif...
متن کاملInternal phloem in an interspecific hybrid of cassava, an indicator of breeding value for drought resistance.
We examined the stem anatomy of Manihot esculenta Crantz and its hybrid with M. oligantha Pax. Cross-sections were stained with safranin-alcian blue. Manihot esculenta and its hybrid were found to have the same vascular structure in bicollateral bundles with internal phloem, which has been associated with drought resistance in other plant groups. If this association is established for cassava, ...
