Abstract:
Fertilizer type, dosage, time and method of application plays a significant role in the yield and postharvest quality of pineapple. To study the effects of calcium on yield and quality of pineapple (Ananas comosus var. Mauritius) foliar spray of calcium nitrate 0.5% at 70 days after flowering (DAF) and soil application of Ayar @ 40g plant⁻¹ at different growth stages were imposed in this field experiment. The yield performance, vegetative characters and physico-chemical qualities were appraised. Treatments expressed no significant difference in vegetative characteristics of the plant but significant differences were observed in fruit yield. Combined application of Ayar @ 40g plant ⁻¹ at the fourth month after planting and foliar spray of calcium nitrate 0.5% at 70 DAF recorded the highest fruit yield with 58.38 t ha⁻¹.
