Integrated weed management practices in gladiolus and their effect on flowering, weed density and corm yield

Abstract

An experiment was during Rabi (winter) season of 2014-15 to study on integrated weed management in gladiolus cv. Pusa Srijana. A set of 11 integrated weed management treatments laid out in simple randomized block design with three replications. The results revealed that the number of monocot and dicot weeds, their fresh and dry weight was recorded maximum under control treatment, while these were least with the application of atrazine 0.75 kg/ha pre-emergence + carfentrazone @ 0.030 kg/ha post-emergence at 40 days after planting. The maximum vase life of spikes (10.3 day) was recorded with the application of pendimethalin 0.75 kg/ha + metribuzin 0.3 kg/ha pre-emergence as compared to control (7.3 day). The yield of corms 89.48 q/ha & cormels and marketable spikes (1.43 lakh per ha), net profit (Rs. 3.48 lakh/ha) and benefit:cost ratio (1.99) was received maximum with the application of metribuzin 0.4 kg/ha pre-emergence + residue (dry grass 5.0 tonnes/ha) over control.
