Pakistani agriculture is largely an economic symbiosis of crop and livestock. But, scarcity of quality forage in the country has made livestock to continually suffer. The micronutrient nutrition of forage crops is important not only for increasing productivity but also for quality of the herbage produced. Pakistani soils are mostly calcareous and alkaline in reaction where availability of micronutrient is a serious problem. Therefore, a research was carried out to study (i) The physico-chemical characteristics of soil and water samples of Sargodha district (ii) Micronutrient status of soil and fodders of Sargodha district and, (iii) the micronutrients (Zn and B) effect on yield, yield components and quality of oat and pearl millet at district Sargodha. For this purpose soil, water and plant samples were collected twice a year during Kharif (summer) 2006 and rabi (winter) 2006-07. The sampling sites were uniformly distributed throughout district Sargodha. From each site, composite soil sample was taken up to 60 cm depth in the order of 0-15, 15-30, and 30-60 cm depths. These soil samples were analyzed for pH, particle size analysis, organic matter and micronutrients i.e. Cu, Zn, Mn, B and Fe. Similarly, associated fodder samples were also analyzed for these micronutrients. While ground water samples were also collected along with soil and plant samples and analyzed for EC, SAR, RSC and Cl -1 . After this, two field experiments at farmer field of Sargodha district were conducted to evaluate the response of micronutrients (Zn and B) to fodder yield and quality of oat and pearl millet. In this study, the soils of district Sargodha varied from loamy sand to silty clays, low in organic matter and alkaline in reaction (pH >7.0). In general, DTPA-extractable xivmicronutrients i.e., Fe, Zn, Cu, Mn and dilute HCl extractable B was higher in surface soil and decreased with depth. During kharif 2006, out of total analyzed soil surface samples 48, 01, 53, 03 and 41% were deficient in Zn, Cu, Fe, Mn and B, respectively. Similarly during rabi (2006-07) 47, 01, 47, 02 and 30% soil samples were deficient in Zn, Cu, Fe, Mn and B, respectively. Soil organic matter, pH and texture had strong influence on the distribution of plant available micronutrients. While correlation coefficients indicated that all micronutrients were positively correlated with soil organic matter. Soil pH had a negative and non-significant correlation with available Zn, Cu, Fe, Mn and positive but non-significant correlation with B in both summer and winter. Further, it can be amply surmised from the above data that light textured soils were mostly deficient in micronutrients (Cu, Fe, and B) as compared to heavy textured soils in summer. While in rabi, Zn availability decreased in coarse textured soils. Similarly, fodder samples were also analyzed for micronutrients (Zn, Cu, Mn, Fe and B). During kharif 2006, plant tissue analysis revealed a 29 and 31% Zn deficiency in millet and sorghum, respectively. Further, 10 and 14% sorghum samples were deficient in Fe and Mn, respectively. Likewise during rabi, only Mn deficiency was observed as 2, 15 and 6% in berseem, lucerne and oat, respectively. While only 2% berseem was found to be deficient for B. Ground water samples were also collected along with soil and plant samples to obtain a general picture of water resources of Sargodha district. Water samples that have EC< 1.0 dSm -1 are considered to be fit for irrigation. Almost 26 and 24% water samples were found to be fit in summer and winter, respectively. Whereas with respect to SAR, 46 and 50% water samples were fit (SAR<6) in summer and winter, respectively. While xv31 and 33% water samples had RSC<1.25 which indicated their suitability for irrigation purpose. In Pakistan, fodder crops are traditionally grown on soils having poor fertility and the use of micronutrients for these crops is negligible. Thus effects of micronutrients (Zn and B) on yield, yield components and quality of oat and pearl millet were studied during rabi 2007-08 (winter) and Kharif 2008 (summer). A factorial combination of three levels of B (0, 1, 2 kg ha -1 ) and Zn (0, 5, 10 kg ha -1 ) were applied. Data were noted for plant height, number of tillers per plant, dry matter yield, crude protein content, acid detergent fibre (ADF) and neutral detergent fibre (NDF). Plant height and tillers per plant showed positive and highly significant correlation with dry mater yield. The results showed that sole applications of B and Zn with their increasing levels significantly increased plant height, number of tillers per plant, dry matter yield and crude protein contents. Besides this, there was statistically non-significant effect of these micronutrients on protein, ADF and NDF of pearl millet. While there was some positive but non-significant effect on ADF and NDF contents of oat with application of these micronutrients. In the past, no survey of the micronutrient deficiencies in a large number of farmers’ fodder fields of Sargodha district has been undertaken. While, the earlier research has mostly concentrated on the major nutrients and the deficiencies of NPK have been reported to be widespread in this system. But our results demonstrate clearly that apart from water shortage and irrigation with brackish water, soil infertility is also the issue for crop production and productivity enhancement in study area. By balance fertilization, good quality fodder can be available throughout the year and ultimately we can perk up the animal productivity up to 50 per cent with existing gene pool. Further, it xviis emphasized that use of brackish water should be avoided to maintain soil health and for sustainable crop yield where good quality water is manageable. However, if the use of brackish water becomes necessary in an area where underground water may be the only source of irrigation, then such water should be used with proper management practices. In future experiments, we should also analyze micronutrient content in the harvested plant tissues after growing the fodders under these treatments. This will provide more information on how the treatments are affecting the micronutrient status of the kharif (Pearl millet) and rabi (oat) fodders when treated with extra B and Zn.

المصادر في القراءات القرآنية بين النصب والرفع

 In Arabic language the source from which all nouns and verbs are derived is called  (المصدر). Verbal noun (Al-Masdar:  (المصدر  is a very important derivative in Arabic. It is a noun derived from the verb to refer to the action or activity implied in the verb, e. G.  ((كتابة   “writing” as a process- derived from the verb (كتب) to  “write”. A verbal noun represents a change in the form of a verb which allows it to be used as a noun in a sentence. Verbal noun is a type of noun which can bear the article (ال) or tanwin   (تنوين ) and can be declined according to the sentence i.e. Nominative, accusative and genitive case. This article deals with the verbal nouns in the Holy Quran that appeared once in the nominative case and in other Qiraat it was read as accusative case. For e.g. (Al-Hamd) is read as nominative and accusative form. الرفع على قراءة حفص: ( الحمدُ لله رب العالمين ) و فى قراءة أخرى : ( الحمدَ لله رب العالمين ) Likewise other examples are: (سورةٌ أنزلناها )- (سورةً أنزلناها) (سلامٌ عليك)- (سلامًا عليك) Similarly : النصب على قراءة حفص: ( و بالوالدين إحسانًا) و فى قراءة أخرى : ( و بالوالدين إحسانٌ) Thus, the article highlights the semantic treasures embedded in the Qiraat of the Holy-Quran.

Evaluation of Rhizobacterial Isolates Against Pythium and Phytophthora Spp. Associated With Chilli and Tomato Crops

Tomato (Solanum lycopersicum Mill.) and chilli (Capsicum annuum L.) crops are of significant importance regarding their nutritional and economic concerns. The yield of the produce is relatively low as compared to the other countries of the world due to pre and post-harvest losses caused by various biotic and abiotic limiting factors. Pythium and Phytophthora spp. are notorious fungal-like pathogenic oomycetes associated with damping off, seed rot and late blight diseases in chilli and tomato crops. Synthetic agrochemicals are extensively used to control these pathogens and can be toxic and can pollute the environment. Moreover, this method of disease control is not much effective due to the soil-borne nature and rapid multiplication ability of these pathogens. The present study was conducted to explore the antagonistic potential of naturally occurring rhizobacteria against these pathogens. For this purpose, an extensive survey was conducted during 2015 - 2016 cropping year in major tomato and chilli growing areas in various districts of Punjab province viz., Attock, Chakwal, Faisalabad, Gujranwala, Gujrat, Jhelum, Okara, Rawalpindi, and Sialkot. The survey revealed maximum disease incidence 45.5 % and 41.6 % from chilli fields in Okara and Sialkot districts respectively while from tomato fields, 40.1 % and 39.15 % disease incidence was recorded from Sialkot and Okara districts respectively. From Phytophthora spp. infected tomato fields, maximum disease incidence was recorded at 66.3 % and 55.6 % from Okara and Sialkot districts respectively. Rhizobacteria are rhizospheric beneficial agents which colonize plant roots, aid in disease suppression and plant growth enhancement. A total of 130 rhizobacterial isolates were recovered from soil. Out of the total, 10 isolates were found highly effective antagonists against Pythium and xxix Phytophthora spp. Based on their morphological, biochemical and molecular analysis these rhizobacterial isolates were identified as Pseudomonas koreensis, P. asaccharolticum, Serratia marcscens, S. marcscens, P. putida, P. putida, P. libanensis, P. aeruginosa, Bacillus subtilis, B. megaterium, B. cereus, B. cereus and Burkholderia spp. All these rhizobacteria were compatible with each other and showed significant antibiotic resistance against Ampicillin and Penicillin G while B. subtilis showed resistance against all the tested antibiotics except Streptomycin and Rifampicin at highest concentration of 500 ppm. Rhizobacteria with high antagonistic potential viz., B. subtilis, B. cereus, P. putida and P. fluorescens were mass cultured on four (4) carrier materials viz, Sugarcane straw, wheat straw, wheat porridge and peat soil. All these rhizobacteria showed maximum viability on sugarcane baggas followed by wheat straw at 4 °C up to eighty (80) days. Seed treatment with rhizobacteria + sugarcane baggas (B. subtilis + SB) resulted into maximum seed germination (98 %), minimum seedling mortality (3.25 %) and improvement in plant growth characters viz, shoot and root length, fresh shoot weight, root weight and vigor index. Out of the ten (10) potential antagonists, nine (9) are first time reported against oomycetes from Pakistan that could be further tested for their antagonistic ability against other phytopathogens.
