Abstract

The objective of present investigation was to compare the effect of foliar application of Ca(NO3)2 (0.2, 0.4, 0.6, 0.8 percent) applied at 60, 75 and 90 days after transplanting (DAT) on vegetative growth and leaf nutrients content with the control (water spray) of strawberry cultivar ‘Winter Dawn’. The experiment was laid out in Randomized Block Design (RBD) and replicated four times. Triple applications of Ca(NO3 ) 2 at different concentrations improved plant growth related parameters viz. plant spread (N-S, 202.0 to 223.8 mm and E-W, 213.3 to 230.3 mm), number of leaves/plant (21.6 to 29.8), crown length (23.6 to 26.1 mm), crown diameter (28.7 to 35.2 mm), plant fresh weight (22.5 to 33.4g ), plant dry weight (7.5 to 10.6g), root fresh weight (3.6 to 5.1g), root dry weight (1.47 to 2.12g), root length (120.7 to 174.0 mm), leaf area index (0.45 to 0.6) and leaf chlorophyll content (45.6 to 53.5) over the control (193.1 mm, 196.4 mm, 19.5, 22.1 mm, 26.9 mm, 20.3 g, 7.1 g, 3.4 g, 1.43 g, 117.9 mm, 0.42 and 44.5, respectively). Foliar feeding with Ca compounds also considerably enhanced leaf N, P, K, Ca, Mg, Cu, Zn, Fe and Mn content and the values ranged from 2.31 to 2.40%, 0.23 to 0.26%, 1.14 to 1.32%, 0.85 to 1.02%, 0.51 to 0.76%, 17.5 to 25.4 ppm, 27.4 to 38.4 ppm, 83.7 to 107.4 ppm and 53.5 to 55.3 ppm, respectively. It is concluded that triple sprays of Ca(NO ) 3 2 @ 0.4 per cent appreciably enhanced vegetative growth characters and substantially leaf N and Ca contents over the control.
