Abstract: A field experiment was carried out to assess the effect of foliar nutrition of calcium and sulphur on growth and yield parameters of papaya at the Horticultural College and Research Institute, TNAU, Coimbatore. The study involved the foliar application of calcium (Ca (NO3)2) and sulphur (K2SO4) independently or in combination at two levels (0.25 % and 0.5 %) with micronutrients (zinc sulphate @ 0.5% and boric acid @ 0.1%) at 3rd, 5th and 7th months after planting along with the recommended dose of fertilizers (50:50:50 g NPK /plant @ bimonthly interval) in randomized block design with three replications. The results showed that the plants treated with foliar application of calcium (0.5% Ca (NO3)2), sulphur (0.5% K2SO4) and micronutrients (zinc sulphate @ 0.5% and boric acid @ 0.1%) along with the recommended dose of fertilizers (T7) registered significantly the highest number of fruits (34.21), fruit weight (1.39 kg), fruit length (29.96 cm) and fruit circumference (41.34 cm). The fruit yield (47.54 kg/plant) registered in this treatment (T7) was 28.21% higher than control in spite of the incidence of PRSV (31.26 %). The same treatment also registered the highest leaf area (2473.45 cm2) and chlorophyll content (1.970 mg g-1).
