This study is an attempt to find best alternative method to estimate reference evapotranspiration (ETo) for the Nagarjuna Sagar Reservoir Project [NSRP], command area located at Andhra Pradesh, India. When input climatic parameters are insufficient to apply standard Food and Agriculture Organization (FAO) of the United Nations Penman–Monteith (P–M) method. To identify the best alternative clima...

This study employs a knowledge intensive corpus analysis to identify the elements of the communicative context which can be used to determine the appropriate lexical and grammatical form of instructional texts. imagene, an instructional text generation system based on this analysis, is presented, particularly with reference to its expression of precondition relations.

Knowing crop water uptake each day is useful for developing irrigation scheduling. Many technologies have been used to estimate daily use. Sap flow one of the that measure through stem a plant and uptake. sensor an effective direct method measuring use, but it relatively expensive requires frequent maintenance. Therefore, alternative methods, such as evapotranspiration based on FAO 56 Penman-Mo...

Wheat is an important crop of India. Precise estimates of evapotranspiration can be obtained by multiplying crop coefficients to reference evapotranspiration using readily available climatic data. PenmanMonteith equation is adopted world wide as the most reliable and accurate method for computing reference evapotranspiration. The Food and Agriculture Organization (FAO) presented crop coefficien...
