Effect of Boron on Cauliflower Production
AbstractThe effect of different levels of boron on cauliflower production was studied in a farmers' participatory on-farm rcsexch approach at Sipadol, Bhaktapur dlstrict during 2001 to 2002. The objective of the experiment was to identify appropriate and economic dose of boron for better cauliflower production in terms of both quality and quality and thus increase the farmers' income. In the expenmental site, cauliflower based cropping patterns; normal season rice-cauliflower and maize-cauliflower are extensively adopted by the farmers. Preliminary soil analytical report also depicts the critically low level of available boron in the study area.This experiment designed in randomized complete block design (RCBD) was consisting of five different level of boron (B) including farmer's practice as a control with four replications. The experimental results revealed the better quality and quantity of cauliflower curd (14.3 and 13.9 t ha-1) from the treatment with 20-kg borax in both the years 2001 and 2002 respectively. Similarly, the higher amount of soils B (0.730 and 0.768 ppm) was extracted in the same treatment (20- kg borax ha-1) as a residual after cauliflower harvest. Response to boron was significant which indcated that the horon (B) is an essential micronutrient for the better quality and quantity of cauliflower production for the study area.
