Three experiments were conducted at Agriculture Research Institute (ARI) Tarnab, Peshawar, Pakistan during the year 2012-14 to study the “Response of tomato to irrigation, foliar application of calcium (Ca), boron (B), zinc (Zn) and post harvest calcium treatments”.In the first experiment, tomato plants were irrigated at 3, 6 and 9 days intervals. The nutrients (Calcium, Boron, and Zinc) content of tomato crop were investigated in relation to irrigation intervals and sampling time (0, 20, 40, 60 and 80 days after transplantation). The yield and quality attributes were evaluated in relation to irrigation intervals only. The highest leaf Ca content (1.19%), leaf Zn content (3.28 mg 100g-1 DW ), number of leaves (129.00 ), leaf area (56.88 cm2), number of flowers (6.33) and fruitcluster-1 (4.33), yield(21.66 t ha-1), fruit firmness (3.33 kg cm-2),lowest blossom end rot (4.80%) and fruit cracking (4.17%) were recorded in plants irrigated after 6 days, while the highest leaf boron content (4.07 mg 100g-1 DW), lowest TSS (1.72 °brix) and non reducing sugars (0.56%) were measured in plants with irrigation after every 3rd days. Root weight (164 g), reducing sugars (3.80%), and ascorbic acid content (13.67mg 100g-1) were recorded as maximum in plants with 9 days irrigation interval. The highest leaf Ca content (1.12%) was recorded in plants, when leaf samples were taken after 60 days, while leaf B and Zn content were recorded the highest i.e. 3.92 and 4.71 mg 100g-1 DW, respectively in tomato leaves, sampled after 80 days.In the second experiment, the effects of calcium, boron, and zinc foliar application on yield and fruit quality of tomato were studied. Calcium (0, 0.3, 0.6 and 0.9%), Boron (0, 0.25, 0.5%) and Zinc (0, 0.25, 0.5%) were applied as foliar spray, three times, 1st before flowering, 2nd at the time of fruit set and 3rd application was repeated 15 days after2nd application. Calcium application at 0.6% increased plant height (88.04 cm), number of primary (2.63) and secondary (7.15) branches, number of leaves plant-1 (182), leaf area (65.52 cm2), number of flowers cluster-1 (6.33), fruit cluster-1 (4.82), fruit plant-1 (66.15), yield (28.11 t ha-1 ) and decreased the flower drop (18.85%). Moreover, The highest number of flower cluster plant-1 (16.78), fruit weight (99.94 g), fruit firmness (2.99 kg cm-2), fruit Ca content (10.21 mg/100 DW), least TSS (3.38 °brix), blossom end rot (6.70%), fruit cracking (3.63%) and Zn content (2.08 mg/100 DW) were recorded at 0.9% Ca foliar application. In case of B levels, more plant height (88.14 cm), number of primary (2.61) and secondary (7.44) branches, number of leaves plant-1 (177), number of flowers cluster-1 (6.06), fruit cluster-1 (4.97), fruits plant-1 (67.78), yield (28.30 t ha-1) and reduced flower drop (17.86%), fruit cracking (4.44%) were recorded with foliar spray of B at 0.25%. Similarly, 0.5% B application significantly increased leaf area (62.33 cm2), number of flower cluster plant-1 (17.42), fruit weight (96.41 g), fruit firmness (2.86 kg cm-2), fruit Ca content (9.97 mg/100DW) and fruit B content (3.24 mg/100DW), lowest blossom end rot (11.44.0%), TSS (3.56 ° brix) and fruit Zn content (2.18 mg/100 DW). Comparing the means for Zn concentrations, maximum plant height (86.53 cm), number of primary (2.53) and secondary (6.42) branches, number of leaves plant-1 (167), leaf area (63.33 cm2), number of flowers cluster-1 (6.06), fruit cluster-1 (4.64), number of cluster plant-1 (16.64), fruit plant-1 (63.78), fruit weight (94.98 g), yield (28.80 t ha-1), ascorbic acid content (14.52 mg/ml), reducing sugar (3.07%),fruit B (3.27 mg/100 DW) and Zn (2.59 mg/100 DW) contents were higher while the incidence of blossom end rot (11.00%), fruit cracking (4.83%), non-reducing sugar content (1.11%) and fruit Ca content (8.88 mg/100DW) were lower with 0.5% foliar Zn application while the effect of Zn on flower drop was found non significant. By contrast, firmer fruit (2.82 kg cm-2) with lowest TSS (3.36 °brix) were recorded in plot, where Zn was not applied. In the 3rd experiment, the fruits of tomato were dipped in different calcium sources (calcium chloride, calcium gluconate, calcium lactate and calcium sulphate) at various concentration (0, 0.25, 0.50 and 0.75) and stored at low temperature (10± 2°C) and ambient temperature (32±2°C) and at relative humidity (60±5%) for 21 days. Higher fruit firmness (2.25 kg cm-2), percent acidity (0.34%), ascorbic acid content (9.90 mg 100g-1), non reducing sugars (1.58%), minimum physiological weight loss (20.18), TSS (4.99 °brix), reducing sugars (3.53%), sugar acid ratio (16.07), soft rot (18.49%) and black mold (16.63%) wererecorded in fruits stored at low temperature, while minimum cell membrane and cell wall ion leakage (41.58 and 22.64%, respectively) and green mold (20.58%) was recorded in fruits stored at ambient temperature. For calcium concentration, Ca at 0.75% significantly increased fruit calcium content (12.89 mg 100g-1), fruit firmness (2.60 kg cm-2), percent acidity (0.38%), ascorbic acid content (9.68 mg 100g-1), non reducing sugars (1.74%) and reduced physiological weight loss (14.33%), cell membrane and cell wall ion leakage (40.25 and 21,38%, respectively), TSS (5.03 °brix), sugar acid ratio (14.03), soft rot (11.02%) and green mold (13.73%) while reducing sugars (3.26%) and black mold (16.0%) were recordedminimum in tomatoes supplied with 0.5% calcium concentration. Regarding the means for calcium sources, more fruit firmness (2.82 kg cm-2), percent acidity (0.44%), ascorbic acid content (13.52 mg 100g-1), non reducing sugars (2.34%), minimum physiological weight loss (12.72%), cell membrane and cell wall ion leakage (37.50 and 19.06%, respectively), TSS (4.96 °brix), reducing sugars (3.10%), sugar acid ratio (11.49), soft rot (6.11%) and black mold (13.17%) and green mold (10.04%) were recorded in fruits treated with CaCl2. Therefore, it is concluded that 6 days irrigation interval resulted in better growth, more nutrient uptake, fruit quality and minimum physiological disorders (blossom end rot and fruit cracking). Calcium decline started after 60 days of growth, so foliar calcium should be applied before flowering and after fruit set to correct the calcium deficiency and control the Ca related physiological disorders like blossom end rot and fruit cracking. Foliar application on Ca, B, and Zn should be used alone or in combination to improve the fruit yield, minimize the physiological disorders and (blossom end rot and fruit cracking) and enhance fruit quality of tomato. Furthermore, CaCl2 at high concentration and low temperature should be used for maintaining quality of tomato fruits by reducing the post harvet diseases, increasing the fruit firmness, delaying ripening process, and prolonging the shelf life.

ضیاء شاہد
(چیف ایڈیٹر ’’خبریں‘‘)
ویکھ ضیاء شاہد نے ہے ’’خبریں‘‘ اخبار نکالا
ایہ تے ہیگا ظلم نوں اُکا مار مکاون والا

فرعوناں دے ظلم توں جس نے کئی مظلوم نکالے
دین دعائیں جنھاں دکھڑے ون سونے جالے
من گئے شاہد دی محنت نوں سب اخباراں والے
ایس ضیاء شاہد دا بس اللہ ہی ہے رکھوالا

جتھے جتھے وی دھرتی تے ظلم دی ہے پچھ پیندی
فر خبریں اخبار دی ٹیم ہے اس تھاہریں جا ویندی
ظالم دی اکھاں وچ اکھاں پا کے ایہ گل کہندی
ظلم غریب تے کیوں کر ڈھایا ، کیوں بھانبھڑ ہے بالا

وڈ وڈیرے جد غریباں اُتے ظلم نیں ڈھاندے
حاکم رل کے ظالم نال انصاف توں نیں کتراندے
آسں امیداں والے بوہے جد نیں بند ہو جاندے
کھلا رکھے دفتر اپنا ایہ نہ لاوے تالا

خبریں دے جو ہین نمائندے ایہناں وچ اچھائی
جھوٹ فریب نہ دھوکہ ہرگز ہر گل وچ سچائی
ایسے لئی خبریں اخبار نے جگ وچ شہرت پائی
شاہد نوں رب صحت دے جو پچھے غریب دا حالا

قادری سائیںؔ رب توں ایہو کردا نت دعا
ضیاء شاہد نوں سوہنا سائیں ہمت کرے عطا
جیہڑا یار غریباں دا کردا ہے انت بھلا
وچ ارائیاں ایس گھرانے دا اُچا ہے بول بالا

بچے کی تعلیم و تربیت میں کردارِ ولی کے عصری تقاضے

This article is about the role and duties of guardian to manage the education of the children and to build up their behavior. So that they may lead the educated, civilized and well managed life and play their role in the development of an Islamic society. The duty of the guardians regarding the education of the child has been divided into four categories, which are education of aticates, religion, reading and writing and general and technical education. The guardians are bound to manage the commercial, industrial and technical education for their male wards and to educate their female wards cooking, tailoring and knitting. Scholastic views of different schools of thought along with their arguments have been discussed in this article.

Body Composition, Elemental Concentration and Morphometrics of Two Carnivorous Fishes in Rivers of Southern Punjab, Pakistan.

Seventy eight wild Wallago attu and eighty Sperata sarwari of different body sizes were collected for analysis of body composition, morphometric parameters and elemental concentration. Each sampled was measured, weighed, dried and powdered for the analysis of water content, ash content, fat content and protein content. It was observed that highly significant inverse correlations exist between percent water content and percent ash content (wet weight), percent fat content (wet weight) and percent protein content (wet weight) in both species. In Wallago attu, there was no effect of wet body weight and total body length on percent water contents but positive influence on percent ash contents (wet weight), percent fat contents (wet weight), percent protein contents (wet weight), percent ash free matter (wet weight and dry weight), percent fat free matter (wet weight) and percent protein free matter (wet weight and dry weight). In case of Sperata sarwari, wet body weight and total body length have positive influence on percent water contents, percent fat contents (wet weight), percent protein free matter (wet weight and dry weight) and negative influence on percent ash contents (wet weight), percent protein contents (wet weight), percent ash free matter (wet weight and dry weight) and percent fat free matter (wet weight). Condition factor has a highly significant positive correlation with percent fat content (wet weight) in both species. When comparative study was done, it was found that there were highly significant differences between these two species in ash contents (wet and dry weight), protein contents (dry weight), ash free matter contents (dry weight), fat free matter (wet weight) and protein free matter (wet and dry weight). There was no significant effect of sex on body constituents in both species. The results also indicated that the proximate composition of the Wallago attu and Sperata sarwari depend on season. It was found that body constituents varied in different months of the year. The predictive equations can be used to estimate values of body composition with a fair amount of accuracy for both species. Flame Atomic Spectrometry was used as an analytical tool for analysis of trace metal concentration in relation to body size. In Wallago attu, it was observed that the metals i.e. Cd, Co, Fe and Cu were found to increase isometrically while Zn, Ni and Pb showed negative allometry with increasing body weight and total length. In Sperata2 sarwari, Cd, Co, Fe and Zn were found to increase isometrically while Ni, Cu and Pb showed negative allometric growth with body weight and total length. In both species, there were not significant differences in elemental concentration with relation to sex. The effect of season on elemental concentration was analyzed by using the ANOVA. Significant differences were observed in case of copper, zinc and lead concentrations in Wallago attu while zinc and nickel concentrations in Sperata sarwari. Wet body weight of both the species was not consistent with the cube law and showed positive allometry. The regression slope was W = 0.001698 L 3.27 for W. attu and W = 0.001698 L 3.28 for S. sarwari. The values of the slope b are significantly higher than b = 3.0, which shows that the weight grows more rapidly as compared to the cube of the length. Regression analysis showed that all the morphometric parameters except for eye diameter, mandible barbells length in W. attu and eye diameter, caudal fin length, nasal barbells length, maxillary barbells length and mandible barbells length in S. sarwari showed isometric growth with relation to wet body weight and total length of the fish. While the regression coefficient of all the fins weight except for dorsal fin in W. attu and caudal fin in S. sarwari showed positive allometric growth with body size. In internal morphometric studies, except for air bladder weight and gonads weight all the parameters showed negative allometric growth with relation to wet body weight and total length.
