Abstract
The physical indices of the soil are
major contributor in growth and yield of the crops. Soil texture is a
stable soil physical characteristic that has an indirect impact on the
crop growth. Present study aims to evaluate the impact of different
textures along with organic amendments on root extension of maize that
ultimately affect maize growth. Pot study comprises two soils from
Faisalabad and Gujranwala origin that are sandy loam and clay loam,
respectively, along with application of farm manure at 0, 5, 10 and 15 Mg
ha-1. Recommended dose of NPK at 120: 60: 40 was applied in
each treatment pot. A significant difference for plant growth parameters
shoot (length, fresh weight and dry weight), root (length, fresh weight
and dry weight) and 1000 grain weight was observed for application of
organic amendment at different rates under different textures. It was
observed that as the organic matter increased there was increase in every
plant parameter but upto 10 Mg ha-1 and then a significant
decrease was observed. It was also observed that crop performed better
under sandy loam texture as compared to clay loam.

Abstract
Resistance
development in arthropods is the natural phenomena that is reinforced
against any unbalanced revolutionize in the execution of any agro
ecosystem. Its intensity has multifold during the management of major
crop insect pests. As a result of misuse of the conventional insecticides
had not only made them ineffective but also threat for new chemistry
insecticides in future. For that purposes a study was planned for
toxicity bioassay against two notorious lepidopterous pests as Helicoverpa
armigera and Spodoptera litura by using nine modern
insecticides each replicated thrice with four different concentrations
and a control. Response, recorded after 48 hours after application,
showed Chlorfenpyr was most effective against S. litura at all
concentrations (100, 93, 100,97,87 and 14% mortality) at
330,165,82.5,41.5,20.6 and 0 ppm (Control) while Leufenuron was least
effective showing highest susceptibility to armyworm as (53, 53, 47, 40,
27, and 33%) from low to high concentration 50,25,12.5,6.25 and 0 ppm.
Similarly Leufenuron was least effectual demonstrated highest
susceptibility to heliothis as (67, 70, 47, 40, 27, and 14% mortality)
from low to high concentration 50, 25,12.5,6.25 and 0
ppm while Chlorfenpyr was highly efficient
against H. armigera at all concentrations (97, 100, 87, 97, 87 and
14% mortality) at 330,165,82.5,41.5,20.6 and 0 ppm (Control)
respectively.

Abstract
The selection of
appropriate sowing method plays a significant role in the placement of
seed at
proper depth and timely sowing, which ensures better germination and
consequent crop growth. An experiment was performed at the
Agronomic research station, Bahawalpur, Pakistan to evaluate the response
of wheat planted with different methods of sowing (With conventional rabi
drill, with coulter drill, broadcast, gup chutt, relay cropping, bed planting
and ridge sowing) during 2011-12. Randomized Complete Block Design (RCBD)
having three replications was used to evaluate the study with plot size
of 6m x 9m. Seed rate was used at 125kg/ha for all the treatments and the
variety used was Maraj 2008. The recommended dose of NPK was applied. The
significant results for germination per square meter (238), productive
tillers per square meter (431.0), plant height (106.33cm), spike length
(12.47cm), number of grains per spike (48), 1000-grain weight (47), biological
yield (12.35 tons ha-1) and grain yield (5.16 tons ha-1)
were recorded where wheat seeds were broadcasted in standing cotton
(Relay cropping).

Abstract
Aedes aegypti is a notorious insect spreading dengue
fever in human being by acting as a vector. Public health problems due to
this vector are present all over the world especially in developing countries
of Asia like in Pakistan. Insecticides are commonly applied to suppress
it population during epidemics. In advances of integrated pest management
the use of less persistence, easily degradable and acceptable
toxicological effects regarding to human health are being preferred on
synthetic insecticides. This study was planned to monitor the effect of
plant extracts, Heliotropium indicum and Mukia maderaspatana,
on different larval instars of and pupae of mosquito vector A. aegypti.
To find the median lethal concentration bio-assay was performed by using
acetone solvent. Research showed that plant extracts were successful to
suppress the mosquitoes population while, essential compounds were
suitable to control the A. aegypti
larvae. Results indicated the potential application of these plant
extracts for eco-friendly management of A. aegypti with respect to public health hygiene.
