Mass Modeling of Castor Seed (Ricinus Communis) with Some Geometrical Attributes

Horticultural crops with the similar weight and uniform shape are in high demand in terms of marketing value. Therefore, an awareness of grading fruits and vegetables based on weight is crucial. A part of this research was aimed to present some physical properties of Castor seed. In addition, in this study the mass of Castor seed variety was predicted with using different physical characteristics in four models includes: Linear, Quadratic, S-curve, and Power. According to the results, all properties considered in the current study were found to be statistically significant at the 1% probability level and the best and the worst models for prediction the mass of Castor seed were based on third projected area and first projected area of the Castor seed with determination coefficients of 0.82 and 0.757, respectively. At last, mass model based on third projected area from economical standpoint is recommended.
