| ABSTRACT: Weeds affect crop growth, health and yield by competing for resources, and they serve as refuge for insect pests. Mulches of different materials have been found to control weeds and insect pests. A field study was conducted at the village of Mang, Haripur, Khyber Pakhtunkhwa, Pakistan, to explore the effect of various mulch materials on weed suppression in maize fields under rain-fed conditions in 2013. Eight mulch materials treatments were used: control (no mulching), wheat straw mulch, dry leaves of eucalyptus, rice straw mulch, grass clippings, living mulch (soybean crop), black plastic mulch and the herbicide Primextra were investigated under a randomized complete block design with four replications. Statistical analysis of data showed... |

| ABSTRACT Field experiment was conducted at the University of Haripur, Pakistan, to explore the role of photothermal units on oil contents, fatty acids profile, yield and yield traits of four sunflower hybrids viz SMH-0917, NK-S-278, SMH-0907 and Hysun-33. These sunflower hybrids were selected because the farmers of that area are mostly relying on these hybrids for sunflower production. Sunflower hybrids were sown in spring and arranged under Randomized Complete Block Design with 3 replications under field conditions. Significant variation (p 0.05%) was found among the sunflower hybrids for photothermal unit requirements for flower completion and physiological maturity. Highest photothermal unit accumulation was found in Hysun-33 followed by SMH-0917 and... |
