| ABSTRACT: This study was conducted to explore the growth stimulating effect of foliage applied brassica water extract on growth and productivity of bread wheat (cv. Punjab 2011) at low and high fertilizer doses. The brassica water extract (5%) and the commercial growth regulator benzyl amino purine (BAP) (5 ppm) were applied alone and in combination at 30 and 45 days after sowing (DAS) under low fertilizer dose (125 kg ha-1 N and 90 kg ha-1 P) and high fertilizer doses (225 kg ha-1 N and 150 kg ha-1 P). Application of the brassica water extract (5%) significantly improved morphological traits such as crop growth rate, leaf elongation, leaf area index, plant height and number of productive tillers under both fertilizer regimes. Similarly, growth regulator... |

| ABSTRACT: In recent decades, allelopathy has gained considerable attention in sustainable agricultural systems. In the current situation, an attempt has been made to investigate the optimal competition period for weed control in maize. Experiments were designed in randomized complete block design and Parthenium hysterophorus was naturally infested in experimental plots during the spring season 2014 to determine the critical competition period for weed control in maize. The relations between grain yield and different competition durations were determined via regression analyses. The experiment comprised seven treatments viz, control treatment, competition for 30, 45, 60, 75, 90 and 105 days after emergence. The results suggested that a weed-free period... |

| ABSTRACT: Weed-induced yield loss in wheat crop is a great threat to food security in Pakistan. A comprehensive understanding of weed-crop competition is very important to develop sustainable and cost-effective weed management. For this purpose, two-year field studies were conducted to determine the effect of different blessed milkthistle densities on the phenology and yield of wheat crop in a rice-wheat cropping scheme in Sargodha, Pakistan during 2013-2014 and 2014-2015. The experiment comprised seven treatments: control (weed free), weedy check (weedy without any control) and blessed milkthistle densities of 5, 10, 15, 20 and 25 plants m-2. In response to increasing weed density, a gradual reduction in yield and yield-related traits of wheat was noted.... |
