Abstract

A pot experiment was conducted to study the genetic variation in calcium uptake and utilization efficiency among three sweet peppers (Capsicum annuum L.): QG, QR, CW under two calcium levels, adequate and deficient (0 and 40 ppm) using a factorial experiment in (RCBD). Calcium level and variety interaction was significant for almost all parameters studied. Major differences were observed among the cultivars in dry matter accumulation in shoot and root, total biomass, and relative deficiency in shoot biomass. Calcium stress factor ranged between 22.6% to 30.3% that is 2 folds differences in relative reduction in shoot dry weight due calcium stress factor among genotypes. Calcium utilization efficiency was almost doubled in cultivars that were grown with no calcium supply compared to these grown with 40 ppm Ca supply. Calcium concentration and uptake in genotypes were significantly different at deficient and adequate calcium levels.
