Evaluation of Rainfall Effect on Programing of Agricultural Management (Case Study: Golestan region)
Abstract
Securing of water need in agricultural is important. Precipitation are one of the most important of water resources in agricultural, in Golestan province, especially , because Alborze mountains are in Golestan south. In research has investigated effects of rainfall to cropping pattern and intensification in Golestan farms. Rainfall used: a) have forecasted rainfalls by Minitab-13 program, b) Different probabilities of rainfalls by LST Program. Then estimated effective rainfall (by USDA method). For optimization used Lingo-8 program. Evaluations shown that in southern region (climate is: smi wet), if rainfall decreased, area of tomato and potato decreased , but canola area increased. In central and north regions (climates are: semi dried to dried), if rainfall decreased, watermelon area decreased, but canola area increased. Also if drought conditions, planting of canola, watermelon and cotton crops are important.
Key words: Cropping pattern, Intensification, Precipitation, Golestan
