Peanuts.pods.gr.w under.r.und and matur. unevenly, r.s.lting that choos.ng the cor.ect time to har.es. is.mor. complicated than other.cr.ps. Pod matur.ty can be deter.ined by blas.ing with a pr.s.ur. was.er.to r.move outer.s.in of the pod (exocar.) to expos. the color.of the middle layer.(mes.car.). The mes.car. color.changes.with matur.ty fr.m white to yellow, or.nge, br.wn and finally black. The s.m of per.entage fr.m or.nge, br.wn, and black mes.car.

The goal of this.r.s.ar.h is.to identify methodologies.to es.imate OBB and BL of the pods.us.ng r.B images.taken in the field and validate the pr.pos.d model us.ng other.pod images. The Mahalanobis.dis.ance clas.ification method was.us.d to pr.ces. s.ts.of images.and calculate pod ar.a (number.of pixels. cor.es.onding to two clas.es.(mes.car. and backgr.und) with nine differ.nt color.gr.ups.
