Abstract
A field experiment was undertaken at Hi-Tech unit, Department of
Horticulture, Rajasthan College of Agriculture, Udaipur to evaluate the effect of
different weed management practices on weeds and cauliflower (Brassica
oleracea var. botrytis L.) cv. Pusa Snowball K-1 during the year 2009-10.
The treatments comprising ten weed control methods were weedy check,
two hand weedings (35 and 60 days after transplanting), black plastic mulch (400
gauge), rice straw mulch and three herbicides (fluchloralin at 1.5 kg/ha,
pendimethalin at 1.5 kg/ha and alachlor at 2 kg/ha) alone and in combination with
one hand weeding at 35 days after transplanting (DAT). Among the herbicides
fluchloralin was applied as pre plant incorporation (incorporated into soil 2 days
before transplanting) while pendimethalin and alachlor were applied 7 hours
before transplanting. These were tested in a Randomized Block Design and
replicated three times.
Results showed that all the treatments significantly reduced the weed
population and biomass over weedy check. However, among the different
treatments the black plastic mulch treated plot showed excellent weed control. The
growth (plant height, spread and number of leaves), quality (compactness, color
and per cent protein content of curd) and yield were also higher under black
plastic mulch but it was not significantly different with rice straw mulch. Among
the herbicides pendimethalin in combination with one hand weeding was found
most effective.
The results further revealed that the rice straw mulch was economically
best treatment as it gave highest benefit cost ratio of 3.48: 1. Thus, rice straw
mulch was the most remunerative for weed control in cauliflower crop.
