INFLUENCE OF INTEGRATED APPLICATION OF PHOSPHORUS ON WHEAT YIELD AND PHOSPHORUS UPTAKE
ABSTRACT:

The solubility and discharge of phosphorus (P) form rock phosphate (RP) is enhanced through mixing of organic amendments. The incorporation of RP to soil may replace chemical phosphatic fertilizers and will reduce the cost of production. Response of wheat crop and P uptake was studied in soil application of phosphorus (P) sources i.e Triple super phosphate (TSP), Single supper phosphate (SSP) & Rock phosphate and Farmyard Manure (FYM) as well as the use of these in combinations in a pot study for two consecutive years. The treatments included; FYM (2.5 & 5 g kg-1 soil), TSP, SSP, RP @ (40 mg P kg-1soil), TSP + (2.5 g FYM kg-1 soil), TSP + (5 g FYM kg-1soil), SSP + (2.5 g FYM kg-1 soil), SSP + (5 g FYM kg-1 soil), RP + (2.5 g FYM kg-1 soil) and RP + (5 g FYM kg-1soil). The experimental layout was completely randomized design (CRD) with four replications. Highest grain (75.8 g pot-1) and straw (94.2 g pot-1) yields were achieved in integrated treatment of TSP + FYM (40 mg P from TSP along with 5g FYM kg-1 of soil). The increase in grain produce was 20% greater as compared to the application of sole TSP followed by SSP (40 mg kg-1 P). Likely, the P uptake in grain (359 mg P Pot-1) and straw (173 mg P pot-1) was also considerably (P ≤0.05) higher in the same treatment (TSP + FYM @ 5g kg-1 of soil). The grain yield of wheat in RP treatment was comparatively lower during 1st year than TSP and SSP treated pots. During 2nd year the wheat yield from the pots treated with 40 mg P in the form of RP + 5 g FYM kg-1 soil was higher than sole TSP and SSP treatment. The efficiency of RP, TSP and SSP was enhanced mixing by FYM that improved the wheat productivity in alkaline calcareous soils.

EFFECT OF IBA AND FUNGICIDES ON ROOTING AND SOIL-BORNE FUNGAL PATHOGENS PREVENTION IN OLIVE VARIETIES
ABSTRACT:

Different treatments of IBA (3500 ppm) alone and in combination with antracol (2%), metagold (2%), Dithane M (2%) and Topsin M (2%) were applied to olive cuttings of three varieties i.e., Chetoui, Coratina and Koroneiki. No fungal pathogenic invasions were observed. Coratina performed best in terms of its root health. IBA alone and IBA in combination with metagold have given good results with increased root development.

STUDIES OF WATER PRODUCTIVITY AND YIELD RESPONSES OF WHEAT SOWN ON BEDS UNDER DRIP IRRIGATION SYSTEM
ABSTRACT:

Drip irrigation practice for intensive row crops like wheat was initially motivated due to very low 
water productivity of wheat with traditional methods of surface irrigation. Enhancing water productivity is one
of the major concerns in developing countries like Pakistan. Therefore, the main aim of this study was to
evaluate the yield responses and water productivity of bed sowing wheat based on drip irrigation system under
loam conditions of soil in arid and semi-arid region. A field experiment comprising of four treatments was
conducted in RCBD fashion at Water Management Research Farm, Renala Khurd, Okara, Punjab, Pakistan
during the winter season of 2018-19 to study the effect of drip irrigation on water productivity and yield
attributes of wheat crop sown on beds. Results revealed that the yield was significantly higher 2.80 t/ha for
wheat sown on 112 cm wide beds having eight crop rows per bed using double lateral under drip irrigation
among other treatments. The treatment having bed width of 69 cm with four crop rows per bed using single
lateral remained at second rank with grain yield of 2.7 t/ha. Data showed that bed sowing technique on 69 cm
wide beds having four crop rows per bed using single lateral under drip irrigation gave highest water
productivity of 1.05 kg/m
, subsequently 76 cm wide beds with six crop rows per bed using single lateral under
drip irrigation showed the water productivity of 0.86 kg/m

Finally, it can be concluded that good management
of irrigation water under drip irrigation is promising for higher grain yield and water productivity and can be
adopted as alternative irrigation system for irrigating field crop like wheat on beds, but more studies must be
conducted under similar conditions.
