A field experiment was conducted to determine effect of spacing on growth and yield of Viola pilosa at UHF, Nauni-Solan during 2002-2003. Study revealed that maximum plant height (19.72 cm) was found in 20×20 cm spacing, which was significantly superior all other spacings. Similarly, number of leaves (19.74), number of flowers (2.32) and fresh and dry flower weight (0.20 and 0.07 g,). The values for yield parameters viz., fresh and dry flower yield (150.0 and 40.0 kg/ha) and fresh and dry herb yield (397.90 and 99.47 q/ha) were maximum in 10×10 cm spacing. The values decreased with the further increase in spacing and minimum yield was obtained at the wider spacing of 30×30 cm.

Abstract


A field experiment was conducted to determine effect of spacing on growth and yield of Viola pilosa at UHF, Nauni-Solan during 2002-2003. Study revealed that maximum plant height (19.72 cm) was found in 20×20 cm spacing, which was significantly superior all other spacings. Similarly, number of leaves (19.74), number of flowers (2.32) and fresh and dry flower weight (0.20 and 0.07 g,). The values for yield parameters viz., fresh and dry flower yield (150.0 and 40.0 kg/ha) and fresh and dry herb yield (397.90 and 99.47 q/ha) were maximum in 10×10 cm spacing. The values decreased with the further increase in spacing and minimum yield was obtained at the wider spacing of 30×30 cm.
