Abstract
The research aims to assess the water needs of crops gardening in Husseiniya land within the province of Karbala, as the province from provices of agricultural economy and horticulture in it make up a large proportion of agricultural investments as an area of cultivated land of gardening agricultural season in 2014 about (54 229) and comprising (46 %) of the total cultivated land of the season with the (117,476) acres. And the importance of water economy (irrigation water) for planting the largest area of arable land, the authors taking the irrigation water for the crop gardening as a target for the research, and analysis of the factors that explain variation of these needs in the study area and then to know the water needs in order to get the evaporation / possible transpiration and find out climatic water balance of the study area in order to know the size of the deficit and surplus water in the region. In order to estimate the irrigation water intake for the crop climate, it has depend the formula (Pliny - Krydl) to calculate the amount of evaporation - transpiration because it is the most accurate equation in estimation water consumption as well as the suitability for climatic characteristics prevailing in Iraq and not dependon by multiple and overlapping climatic elements, as it took from the monthly temperatures average and the percentage of the number of daylight hours basically for estimating the amount of water consumption of agricultural crops
