Effect of foliar application of Ca, Zn, Fe and B on growth, yield and quality of papaya var. Taiwan Red Lady

Abstract

A study was undertaken to assess the effect of foliar application of Ca, Zn, Fe and B on growth, yield and quality of papaya (Carica papaya L.) var. Taiwan Red Lady. Results revealed that the foliar application of calcium nitrate 1000 mg/l + borax 30 mg/l + zinc sulphate 200 mg/l + ferrous sulphate 200 mg/l (T10) at 60, 90 and 120 days after planting were found to be best with respect to plant height (136.20 cm), stem girth (36.50 cm) as well as leaf area (1089.53 cm2) with total yield and quality parameters as compared to other treatments. However, foliar application of borax 30 mg/l resulted in earliness in initiation of flowering (93.40 days) of papaya var. Taiwan Red Lady.
