Abstract
In order to assess the trend in area, production and productivity of major pulses (red gram, bengal gram, horse gram, green gram and black gram) across Karnataka, 22 years secondary data were used. To know growth trends different polynomial linear models
(linear, quadratic, cubic), intrinsically linear models (logarithmic, inverse, compound, power) and non-linear models (log-logistic, exponential) were fitted. Appropriate models were selected on the basis of important model adequacy tests. All the characteristics in red gram showed an exponentially increasing trend, while in bengal gram productivity was linearly increasing whereas area and production showed exponential trend. Cubic and linear models was performed well in majority of situation for green gram and black gram. Quadratic model was well suited for productivity of horse gram, while different modelswere found to be best fit for other characteristics. By trend analysis it can be inferred that different growth trends were observed in each of the crops studied. Further to study the spatial variations in area, production and productivity across major pulses growing districts of the State in different study period, Coefficient of variation (CV%), Coppockās instability index (CII) and Cuddy Della Valle index (CDI) were adopted. Bengal gram and black gram showed high instability during Period II. More instability in area, production and productivity was noticed in Vijayapura, Gadag, Mysuru, Bagalkot and Bidar districts for red gram, bengal gram, horse gram, green gram and black gram respectively, it may be due to these crops are grown in these districts under rainfed conditions.
