The study was conducted to evaluate the effect of mulches and irrigation frequencies on growth and yield of sunflower in the experimental field of oilseed section, Agriculture Research Institute, Tandojam The experiment was laid out in Randomized Complete Block Design with four replications. Plot size kept was 3x3 m different mulches viz., control (No mulch), wheat straw, sugarcane trash, and plastic sheet mulch, and different levels of irrigation viz., 2,3,4 and 5 were tested. Results showed significant differences for seed germination m-2, seed head-1, seed index (g) and seed yield kg ha-1 as affected by different mulches and irrigation frequencies. Results revealed that plastic sheet mulch had maximum (2260.50 kg ha-1) seed yield. The yield contributing parameters such as seed index (g) and seed yield kg ha-1 were also significant under plastic sheet mulch treatment. Results concluded that Plastic sheet mulch produces more yield by cons erving more moisture and having effective weed control. Thus Plastic mulch had better performance and could be used as good option for increasing sunflower yield, four irrigation was found economical for better yield.
