Crop Irrigation Scheduling via Simulation-Based Experimentation
Intraseasonal water allocation to a single crop has been studied extensively. Previous studies have emphasized the need to coordinate irrigation scheduling with several factors including economic and physical constraints, amount of soil moisture available at the time of irrigations, growth stage of the plant, interactive effects from previous and/or subsequent irrigation, and the effect, timing...
متن کاملOptimal deficit irrigation using AquaCrop model: a methodology study
Both developing and developed countries have problems with availability of water to increase agricultural productivity. The importance of improving water efficiency in agriculture has been the subject in many research papers. The usual approach to limit water consumption in agriculture at the district and farm level is to apply water quotas. These quotas may be either for the whole season or fo...
متن کاملGrowth and yield response of potato genotypes to deficit irrigation
In Ardabil region potato crop needs several irrigation, however ground water supplies arebeing exhausted due to reduced precipitation and intensive irrigation. In this research droughttolerance of 10 commercial potato cultivars was studied at three irrigation treatments (100%,80% and 60% of required irrigation water) in Ardabil in a two years field study, 2013-2014.At harvest, marketable tuber ...
متن کاملKnowledge and Practice of Malaria Prevention Methods Among Residents of Arba Minch Town and Arba Minch Zuria District, Southern Ethiopia
BACKGROUND To date, there is no effective vaccine or no effective drug for mass chemoprophylaxis against malaria. Thus, proper know-how and use of prevention methods is crucial. This study aims to assess the knowledge and practice of malaria prevention methods among the residents of Arba Minch area, Southern Ethiopia. METHODS A community-based cross-sectional study that utilized a two-stage s...
متن کاملEffect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation
Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...
