The present investigation was aimed at enhancing the quality and productivity of barley by the fertilizer and chitosan application. The field experiments were conducted in the northern region of Jordan, under the rain fed conditions in the main growing seasons of 2014/2015 and 2015/2016. The experiment was conducted in a well-designed split-plot having three replications and two fertilizer levels (0 and 100 kg•ha-1 DAP (Diammonium phosphate 46% P 2 O 5). Chitosan, in three different concentrations (0, 5, and 10 g•L-1), was randomly applied to all fertilized plots as subplot treatments. The results revealed the highest seed dry weight (5.8 g per plant) in the plants treated with 100 kg•ha-1 of DAP, while the lowest (5.2 g per plant) was recorded in the control which exhibited an increase of about 10%. However, other parameters, namely the number of grains, number of spikes, and number of grains were also found to be influenced by the chitosan treatment. Significant variation (P<0.01) were also high between the lines in the presence and absence of chitosan application. The highest number of grain yield, number of spikes, and grains/spike were found by the foliar treatment of 10 g•L-1 chitosan to barley plants at the tillering stage. Similarly, the grain quality, particularly with respect to protein and starch, was found to be enhanced significantly over control. The highest protein (12.6%) and starch (62.3%) were obtained with 100 kg•ha-1 DAP fertilizer level mixed with 10 g•L-1 chitosan. Hence, based on results, it can be concluded that the fertilizer level 100 kg•ha-1 DAP combined with 10 g•L-1 chitosan is economically best and recommendable for improving the quality and productivity of barley in the northern region of Jordan.

Phosphorus (P) unavailability and lack of organic matter in calcareous soils in semiarid climates are the major reasons for low crop productivity. This field experiment was conducted at the Agronomy Research Farm of The University of Agriculture Peshawar, during the summer of 2015 to investigate the impact of plant residues (PR) (faba bean, garlic and paper mulberry residues) and phosphorous sources [(60 and 120kg ha-1) from single super phosphate (SSP) and poultry manure (PM)] with (+) and without (-) phosphate solubilizing bacteria (PSB) on the phenological development, growth and biomass yield of hybrid maize “CS-200”. Among the PR, application of faba bean residue was found to delay phenological development (days to tasseling, silking and physiological maturity), improved growth (taller plants, higher leaf area per plant and leaf area index) and produced the highest biomass yield (faba bean>garlic>paper mulberry residues). Application of P at the rate of 120kg ha-1 from the inorganic source (SSP) was more beneficial in terms of better growth and higher biomass yield (120-SSP≥120-PM>60-SSP>60-PM kg P ha-1). The plots with (+) PSB showed enhanced phenological development, produced significantly taller plants with higher leaf area per plant and leaf area index and produced the highest biomass yield. On the basis of these results we concluded that the application of faba bean residues, phosphorus at the rate of 120kg ha-1 either from organic or inorganic sources with the inoculation of seed with PSB improved the growth and total biomass of hybrid maize in the study area.

Objective: To assess the efficacy, safety and complication of Barcat_Redman urethroplasty technique in the managementof distal hypospadias. Place of S t u d y : Prospective study was completed at Urology Department, Services Hospital Lahore and larkana from1998 to 2007. Material a n d M e t h o d s : Fifty patients of distal hypospadias were selected from the Urology Department of Services HospitalLahore and Larkana for Barcat_Redman urethroplasty technique. R e s u l t s : Age of the patients range from 5 to 25 years, the mean age was11 years. Forty (80%) patients belonged to urban areas while 10(20%) were of rural areas.AII the patients presented with dystopia ofexternal urethral meatus and chordee (ventral curvature) while 25 (50%) presented wih misdirected stream, 3(5%) spraying of urine and3(5%) narrow stream . The subcoronal type of distal hypospadias was commonly seen in our study, forty (80%) patients had subcoronaland 10 (20%) distal penile urethral opening. Following barcat-redman technique 35(70%) patients had good result and 8(16%) patients weredeclared as fair result while 4 (14%) decleared failure. The overall morbidity rate was 30% while hospital stay was 3 days. C o n c l u s i o n :Barcat-Redman urethroplasty technique is simple, less time consuming and has better success rate for the management of Distalhypospadias.
