| ABSTRACT The present study was conducted to investigate the allelopathic effects of Prosopis juliflora (Sw.) DC. (Mesquite) on various growth parameters of three promising grass species (Cenchrus ciliaris, Panicum antidotale and Panicum maximum) on the Potohar Plateau, Pakistan, under nursery conditions. The experiment was carried out under a completely randomized design with two factors and three replicates. Different concentrations of the foliage aqueous extract of P. juliflora were prepared and their effect was studied on root length, shoot length, fresh and dry biomass of tested grass species. All grass species showed a concentration dependent inhibition. However, among all grasses, C. ciliaris was affected most severely whereas P. antidotale was the... |

| 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... |

| ABSTRACT: Tillage practice has a significant role on weeds eradication and soil water conservation in crop production. Under semiarid agriculture, the monsoon rains (65%) are major source of water in Potohar, Pakistan, which can effectively be used mostly for winter crops production. To evaluate the impact of different tillage system for prevailing cropping systems and their weeds biomass under semiarid conditions, field experiment was conducted at the Arid University Research Farm Koont Rawalpindi (Pakistan) during crop growth seasons 2013-14 and 2014-15. Tillage systems as treatments were (a) three cultivations with a cultivator, as control treatment, (b) mold-board with two cultivations, (c) chisel-plough with two cultivations and (d) minimum tillage... |
