SIMULATED YIELD AND WATER DEMAND FOR CHILLI PEPPER PRODUCTION IN THE DRY SEASONS IN FLOOD- AFFECTED CHAU PHU DISTRICT /Nguyen Van Tuyen [...và nh.ng.kh.],Scientific Journal Of Thu Dau Mot University , No 6(31) – 2016, Dec. 2016

Storing flood water and subsequentlyusing it for rice-based upland crop production in the dry season is an issue for sustainable agriculture in the Mekong Deltaof Viet Nam. An on-farm trial, conducted in between August–December2015in the Chau Phu district of An Giang province, was conducted to determine irrigation requirementand water use efficiency of chilli pepper that couldreplace a rice crop in the dry season in the flood-prone areasfor higher water use efficience. Irrigation requirement and yields of chilli were simulated by using the AquaCrop software (version 4.0) with various varietiesfor air temperaturesand water irrigation level. Results showed that simulated yield of chilli pepper was 6.13 ton per hectare, and this simulated yield was similar tothe practical harvesting yield of chilli pepper (6.33 ton per hectare).This water volume accounted for 59% of output components of the water storage. The study revealed that changes in rainfall and temperatures significantly influence irrigation requirement and the yield of chilli pepper. Irrigation requirement is expected to increase as the temperatures rise. Irrigation requirement is expected to increase as the rainfall reduce.Further studies for other crops and ways of how to reduce pond storage waterlosses by evaporation and seepage are necessary.
