dc.description.abstract | Wheat production in India is about 70 million tonnes per year which counts for approximately 12 per cent ofworld’s production. Being the second largest in population, it is also the second largest in wheat consumption afterChina, with a huge and growing wheat demand. Major wheat growing states in India are Uttar Pradesh, Punjab,Haryana, Rajasthan, Madhya Pradesh, Gujarat and Bihar. All of north is replenished with wheat cultivation. UttarPradesh, the largest wheat growing region of the country, produces around 28 million tonnes of wheat and Biharproduces around 5 million tonnes. The usual parametric approach for growth rate analysis is to assume multiplicativeerror in the underlying nonlinear geometric model and then fit the linearized model by ‘method of least squares’. Thispaper deals with a critical study of wheat yield of Uttar Pradesh with a non-linear approach. The available data of riceduring different years is taken into consideration and different statistical models are fitted for that. The time seriesdata on annual yield of wheat in UP from 1970-2010 were collected from various sources. Growth rates are computedthrough non-linear models, viz. Logistic, Gompertz and Monomolecular models. Different nonlinear proceduressuch as Gauss-Newton Method, Steepest-Descent Method, Levenberg-Merquadt Technique and Do Not Use Derivative(DUD) Method were used in this study to estimate the nonlinear growth rates. The results showed that logistic modelperformed better followed by Gompertz and monomolecular | en_US |
