Decomposition analysis and acreage response of chickpea in western Vidarbha

Abstract

In the present investigation, an attempt was made to study the decomposition and\racreage response of chickpea in western Vidarbha. The study was based on time series secondary data\ron the rainfall, farm harvest price and other data, which were obtained from various Government\rpublications. Nerlovian lagged adjustment model (1958) was used in acreage response analysis based\ron time series data. The study revealed that the compound growth rate for area and production under\rchickpea was recorded high during period I in all the districts. During period II, the area, production\rand productivity of chickpea registered mostly negative growth rates in all the districts. During period\rIII, the compound growth rate for area, production and productivity under chickpea has increased in all\rthe districts of western Vidarbha region. During overall period, the co-efficient of variation and Coppock’s\rinstability index for area, production were high in Yavatmal district compared to other districts. At\roverall period, the area effect (37.44%) was most responsible factor for increasing production in Amravati\rdivision with positive yield and interaction effect i.e., 6.78 per cent and 55.69 per cent, respectively.
