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.
