Two-year long field study was conducted using a permanent layout to investigate the economics of crop residues incorporation (2 t·ha-1) and P application (0, 40, 80 and 120 kg P2o5 ha-1) to directly sowing of rice and wheat crops gown under naturally salt-affected calcareous soil (ECe = 4.59 dS m-1;pHs = 8.38;SAR = 6.57 (mmolc L-1)1/2;CaCo3 = 3.21%;Extractable P = 4.07 mg·kg-1;sandy clay loam) at farmers field in district Hafizabad during the year 2012-13. Split plot design (crop residues in main plots and P application in sub plots) was followed with three replications. Agronomic data on growth and yield were collected at the time of each crop maturity. Maximum growth and yield of both the crops were harvested from the plots where P2o5 was applied @ 80 kg·ha-1 along with crop residues incorporation. on an average of two years, maximum paddy (3.26 t·ha-1) and wheat grain (3.56 t·ha-1) yield were produced with P application @ 80 kg P2o5 ha-1 along with crop residues incorporation. Although, the yield harvested with this treatment (80 kg P2o5 ha-1 + crop residues) performed statistically equal to 120 kg P2o5 ha-1 without crop residues incorporation during both the years, however, on an average of two years, grain yield of directly sowing rice and subsequent wheat was significantly superior (22% and 24% respectively) than that of higher P rate (120 kg·ha-1) without crop residues. overall, continuous two-year crop residues incorporation further increased (17%) paddy yields during the follow up year of crop harvest. Economic analyses of both the crops were carried out to choose the best treatment with adequate economic benefits as compared to those without crop residue incorporation. Maximum net benefit of Rs = 108,680/- for direct seeded rice and Rs = 99,362/- for wheat grown with 80 kg P2o5 ha-1 application under crop residues incorporation was determined. Among P application treatments without crop residues incorporation, the maximu

An experiment was conducted to compare the forage yield and qualify of oat (Avena sativa L.) genotypes (F-413, SGD-46, F-408, F-301, SGD-2011, SGD-3, SGD-37, SGD-40, SGD-5 and S-2000) at Fodder Research Institute, Sargodha, Pakistan during the year 2011 to 2012. Experiment was laid out in randomized complete block design (RCBD) having three replications and a net plot of size 1.6 × 5 m. The varieties were differed significantly (P ≤ 0.05) in yield, growth and quality parameters. The variety SGD-40 produced significantly higher green forage yield (80.00 t·ha-1) and dry matter yield (10.95 t·ha-1) than other varieties due to taller plants (145.73 cm), more number of tillers (7.78 m-2) and leaf area per plant (95.08 cm2). It also had the highest crude protein percentage (13.84%). Correlation analysis of quantitative and qualitative characters indicated the strongly positive association of green forage yield with dry matter, crude protein and ash content. While green forage yield was negatively correlated with the number of tillers per plant, keeping in view both forage yield and crude protein contents the genotype SGD-40 grown under the condition of Sargodha (Pakistan).
