Abstract:
Studies on varying plant densities and nitrogen on the plant, first and second
ratoon crops of kew pineapple under rainfed condition revealed that among the five plant
densities tried, 53330 plants/ha (24 x 45 x 105 cm spacing) recorded the highest fruit yield/ha.
Low plant density of plants/ha (30 x 60 x 120 cm spacing) increased the length, breadh and
weight of fruits. The quality characters viz., TSS (Brix), reducing and total sugars were
maximum under low density while high density increased the acidity and ascorbic acid
contents of the fruits. The mean fruit weight and the highest hectare yield were recorded
at 600 kg N/ha. Nitrogen application increased the reducing and total sugars and decreased
the TSS, acidity and ascorbic acid contents of the pineapple fruit.
