Yield response to water
Part A of Irrigation and Drainage paper No. 33

In this section we present the original version of Part A of the Irrigation and Drainage paper No. 33 as published in 1979. Part A is titled "Yield and Water" and describes the methodology to calculate maximum and actual yield and yield response to water. Furthermore it contains some examples of its practical applications and its use in adaptive research.
	Preface and Introduction
I.	Maximum Yield (Ym)
II.	Maximum Evapotranspiration (ETm)
	1. Reference evapotranspiration (ETo)
	2. Crop coefficient (Kc)
	3. Maximum evapotranspiration (ETm)
III.	Actual Evapotranspiration (ETa)
	1. Adequate soil water
	2. Limited soil water
IV.	Actual Yield (Ya)
V.	Yield Response Factor (Ky)
VI.	Application in Planning, Design and Operation of Irrigation Projects
	1. Adequate water supply
	2. Limited water supply
	3. Additional related applications
VII.	Adaptive Research
	1. Site selection
	2. Irrigation treatments
	3. Experimental design
	4. Data collection
	5. Evaluation and presentation of results
Follow this link to see Part B of "Yield response to Water" (Irrigation and Drainage paper No 33) which is titled "Crop and Water". In Part B there is information on yield and water relations by crop.
