  Direct drilling of wheat in to rice stubbles through zero tillage drill has eliminated the time for land preparation and improved crop stand establishment. In rice-wheat area, the adoption of zero-tillage is growing with the passage of time. The study was performed in Kala Shaha Kaku and Muridkay during 1998-99 to determine the optimum time for first irrigation and nitrogen application in zero tillage wheat in rice-wheat area of Punjab. In the first trial, the treatments included first irrigation at sowing, at emergence, two weeks after emergence and four weeks after emergence. In the second trial, treatments included all nitrogen dressed at sowing, half nitrogen dressed at sowing and half at first irrigation and all nitrogen broadcasted at first irrigation and all nitrogen broadcasted at sowing. The results indicated that emergence, tillering, grain and biological yield was significantly higher when the first irrigation was applied 2 to 4 weeks after emergence. Timing of nitrogen application did not significantly affect the heads per m2, grain yield and biological yield of zero tillage wheat. However, the split application of urea at planting and at first irrigation could improve zero tillage wheat production.

  Background and Objective: Wheat crop is among the leading cereals and its grain is used as a staple food in many countries of the world. Several environmental factors are effecting the performance of wheat crop. Late plantation of wheat crop in Pakistan is one of the factors that reduce the yield. The main aim of this study was to identify and select superior wheat genotype with good adoptability to sowing time under the current changing climatic scenario. Materials and Methods: The present study was carried out to screen newly developed wheat lines across different sowing dates to identify appropriate planting time for these new lines. A set of 7 wheat genotypes was planted on different sowing dates, starting from October, 25-December, 25 with 10 days interval. Results: Data analyses revealed significant effect of sowing time on overall performance of wheat genotype was observed. On the average, wheat crop sown till 15th of November gave better results whereas delayed sowing resulted in reduced grain yield. Similarly, the genotypes also exhibited significant variable performance across different sowing time. However Pr-128 performed well across all sowing dates and was also identified as stable genotypes in overall performance across various sowing dates. Conclusion: From the present study it could be suggested that the most optimum time for sowing of wheat crop is 5-15 of November. Moreover, the genotype Pr-128 in addition to normal sowing it can also be used as short duration variety in those areas where the wheat sowing is delayed due to late harvesting of other crops i.e., Maize, sugarcane etc.

  Study was carried out to determine the level of resistance in Tribolium castaneum (Hbst.). Strains collected from various localities of the Punjab and exposed to different concentrations of phosphine, viz; 0.01, 0.02, 0.03, 0.04 and 0.05%. Higher concentration (0.05 percent) gave higher mortality (90.721-100 percent) under test. While LC 50 values calculated for Sargodha, Kalar-Kahar, Chiniot, Moza Matu, Noorwala, Okara, Jhang, Mamukanjan, Faisalabad, Lahore and susceptible strains of T. castaneum were 0.0220, 0.0115, 0.0176, 0.0132, 0.0136, 0.0163, 0.2010, 0.0186, 0.0193, 0.0192 and 0.0030, respectively, and the level of resistance in these strains ranged from 3.787 to 7.255.

  A comparative study was carried out on mixed fruit jam of (apple+pear) pulp, incorporated within the ratios 50:50 (T1), 60:40 (T2), 40:60 (T3), 100% apple (T4) and 100% pear (T5). All the jam samples were stored in sterilized glass jars and evaluated physicochemically for ascorbic acid, acidity, pH, total soluble solids, reducing sugars and non reducing sugars for an interval of 15 days during 3 months storage period. All the samples were significantly different at (p<0.05) during storage. A decrease was observed in ascorbic acid from 17.40 mg/100 g to 9.19 mg/100 g, pH 3.64 to 3.22 and non reducing sugars 46.00% to 16.69%. While increase was noted in % acidity from 0.60% to 0.78%, reducing sugars 16.55% to 47.30% and TSS 68.5 ºbrix to 71.2 ºbrix during evaluation.

  This study was carried out to find the influence of chemical preservative of potassium sorbate on the preservation and overall quality of individual and blended juices of apricot and apple fruits. Ten different treatments were prepared from these juices. They were analyzed for physio-chemical properties (ascorbic acid, acidity, pH reducing and non-reducing sugars). Ascorbic acid reduced minimal in T1 (3.64) while maximum in T10 (4.94), acidity of samples increased minimum in T5 (0.39), while maximum in T1 (0.48). pH of sample reduced minimum in T2 (3.40) while maximum in T1 (4.00). Reducing sugar increased minimum in T2 (6.47), while maximum in T10 (6.96) and non-reducing sugar increased minimum in T3 (1.08), while maximum in T9 (2.83) all the samples remain acceptable during storage period.
