1) To analyse the operation-wise cost of cultivation of selected crops among bore-well owning farmers,

2) To find out water use efficiency of selected crops in relation to value of output and profit of the crops,

3) To compare the income and profitability of selected crops among bore-well owning farmers.

Selection of thestudyarea: South Gujarat regions will be selected forthe study for the purpose of three major crops are water intensive with low water depletion rate of precipitation.

Sampling procedure: To achieve the objectives of the present study the purposivesampling will be used for the selection of the farmers.

Selection of district

The three major water intensive crops like Paddy, Banana, and Sugarcane selected for the present study Three districts will be selected purposively according to area under cultivation. One district from each cropwill be selected on the basis of triennium average from 2018-19 to 2020-21. Thus, Valsad for irrigated rice and Surat for Sugarcane and Bharuch for Banana is selected for the study.

The study will be carried out by using field survey data from farmers have been using groundwater predominantly for cultivating crops such as banana, sugarcane and paddy. The present study attempts to analyse the water use efficiency in these three crops.

For this, three villages (one for each crop) will be selectwith the help of officials of the Agriculture Department of each district looking concentration of borewell irrigation farmers. As regards the selection of sample for the study, a total of 300 farmers consisting of 100 banana, 100 sugarcane and 100 paddy cultivating farmers will be select purposively.

Analytical Procedure

The major aim of the study is to find out the water use efficiency of three selected crops. Water use efficiency can be estimated by employing different methods. In this study, Water use efficiency is estimated in three ways:

Further to support the descriptive analysis of water use efficiency, multiple regression analysis was also carried out by treating VOP as dependent variable and water consumption andothers as independent variables. It is well known that value ofoutput of three different crops is determined by various factors. A total of nine independentvariables were used to construct the multiple regression. The reduced form of regression model used in the analysis is as follows:

VOP = a+b1 AGE+ b2 EDU +b3SC + b4 FER + b5 FYM + b6PST + b7 WAI + b8 IRR+ u....(1)

Where,VOP = Value of Output(Rs/acre)

AGE = Age of Farmers (Years)EDU = Education of Farmers (Years)

SC = Seed Cost(Rs/acre) FER = Fertilizers cost(Rs/acre)

FYM = Farm Yard Manure cost(Rs/acre) PST = Pesticides cost(Rs/acre)

IRR = Cost of HP hours of water consumption. (Rs/acre) WAI = Weeding and Interculture cost(Rs/acre)

a = constant

b = regression coefficient to be estimated.

u = error term
