ABSTRACT
The effect of various management options like herbicide types and varying spacings on economic traits in wheat were studied. The factors included were: three varieties, three types of herbicides-broad-spectrum, broad leaf, grassy leaf herbicide and a control plots following row spacings of 18, 25 and 32 cm. The biological, grain and straw yield, net income and cost benefit ratio were significantly affected by varieties, herbicides and row spacings. Interaction between varieties and row spacings was significant for biological and grain yield and net income. Among varieties Bakhtawar-92 had maximum biological yield, grain yield, straw yield, net income and benefit cost ratio over Ghaznavi-98 and Inqilab-91. In case of herbicide treatment, broad-spectrum herbicides had higher biological yield, grain yield, straw yield, net income and benefit cost ratio over broad leaf, grassy leaf herbicide and weedy check. Within row spacing, 18 cm space had maximum biological yield, grain yield, straw yield, net income and benefit cost ratio over 25 and 32 cm row spacings, respectively. In the interaction of varieties and row spacing, highest had been found in var. Bakhtawar-92 with 18 cm row spacing for biological yield (14.81 t ha-1), grain yield (4.93 t ha-1) and net income (Rs. 37894 t ha-1). It is concluded that for integrated weed management in wheat, variety Bakhtawar-92, broad-spectrum herbicide and 18 cm spacing may be integrated.
