The performance of the Paci¢c white shrimp Litopenaeus vannamei (Boone) under various stocking strategies was evaluated in earthen ponds ¢lled with freshwater amended with major ions. Six 0.1-ha earthen ponds located in Pine Blu¡, AR, USA, were ¢lled with freshwater in 2003 and 2004, and potassium magnesium sulphate added to provide 50mgK L 1 and stock salt added to provide 0.5 g L 1 salinity. ...
The challenges of soil degradation and climate change have led to the emergence Conservation Agriculture (CA) as a sustainable alternative tillage-based agriculture systems. Despite recognition positive impacts on health, CA adoption in Africa has remained low. Previous health studies mainly focused ‘scientific’ measurements, without consideration local knowledge, which influences how farmers i...
Abstract A field experiment was carried out during the seasons 2016 and 2017 in farm of Department Field Crops Science, College Agricultural Engineering Sciences-University Baghdad to evaluate effect of(Aminopyralid + Flurasulam, Coldinafop-propargyl Flucarbazone-sodium) herbicides seeding rate (100, 125 150) Kg.ha -1 interaction between them growth characteristics, grain yield components wheat...

Two inorganic fertilizers like level viz; nitrogen-control 0 kgha-1 (N0), 100 (Nı), 150 (N2) 20...
Line WB73-6 (Trompillo, CMB74A-432-25B-1Y-IB-1Y-OB) was first introduced in Iran through a nursery received from CIMMYT in 1989. It was selected in a preliminary experiment in Zabol research station among the genotypes of IBON in 1990. In other preliminary and advanced yield trails carried out in Zabol and other stations in southern provinces of Iran with warm climate in 1991-1997, line WB73-6 ...
Field assessment of integrated management BT cotton pests was carried out in two consecutive seasons; 2016/2017 and 2017/2018 the experimental research farm Kassala University, Sudan. Four insecticides (imidacloprid, abamectin, profenofos, lufenuron) from different chemical groups with a mode action three levels (43.81 kgha-1, 87.62 131.43 kgha-1) soil-applied nitrogen were tested IPM package. ...
katoul is a new soybeam cultivar originated from a genotype named d.p.x.3589 imported from the united states of american in 1990. this genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in gorgan and other research stations during 1999-2002. the mean seed yield of d.p.x.3589 in all these experiments was 3333 kgha-1 ...
