A field experiment was conducted for agro-economic assessment of different sesame based intercropping systems at Agronomic Research Area, University of Agriculture, Faisalabad, Pakistan. The treatments were sesame alone, green gram alone, cowpea alone. single row of sesame+single row of green gram; two rows of sesame+single row of green gram; three rows of sesame+single row of green gram; single row of sesame+single row of cowpea; two rows of sesame+single row of cowpea and three rows of sesame+single row of cowpea. The results revealed that the different yield components of sesame were affected considerably by varying number of rows in intercropping. The maximum number of plants m-2 (35.33), plant height (139.03 cm), number of pods per plant (32.20), 1000-seed weight (3.57 g), biological yield (4531.00 kg ha-1), seed yield (900.53 kg ha-1) and oil yield (455.21 kg ha-1) were recorded where three rows of sesame was intercropped with single row of green gram while the highest Land equivalent ratio (1.31), net income Rs.77523 and benefit cost ratio (2.39) was attained where single row of sesame was grown with single row of green gram. Data predicted that single row of sesame grown in association with single row of green gram utilized the resources more efficiently than grown alone.

Zinc shortage is the leading problem in the world, resulting in the reduction of maize yield. Therefore, an experiment was carried out to evaluate the influence of zinc sulphate as foliar application on the yield and quality of maize (Zea mays L.) The treatments were: Control, one water spray at 4-5 leaves stage, one foliar spray of 0.5% ZnSO4 at 4-5 leaves stage, two water sprays (1st at 4-5 leaves stage and 2nd after one week), two foliar sprays of 0.5% ZnSO4 (1st at 4-5 leaves stage and 2ndafter one week), three water sprays (1st at 4-5 leaves stage 2nd and 3rd after one-week interval) and three foliar sprays of 0.5% ZnSO4 (1st at 4-5 leaves stage and 2nd and 3rd after one-week interval). Data regarding various parameters showed that three foliar sprays of 0.5% ZnSO4 (1st at 4-5 leaves stage 2nd and 3rd after one-week interval) gave significantly higher plant height (159.73cm), 1000- grain weight (294.90), number of grains per cob (401.83), grain yield (6.10 t ha-1), biological yield (16.58t ha-1) harvest index (36.78%) and protein content (10.02%). The maximum economic return (Rs.71742 ha-1) for maize hybrid-6525 under agroecological conditions of Faisalabad was obtained where three foliar sprays of 0.5% ZnSO4 (1st at 4-5 leaves stage 2nd and 3rd after one-week interval) were applied. So, keeping in view the above stated results, it can be concluded that, higher yield, quality and more economic benefit can be obtained by applying the three foliar sprays of 0.5% ZnSO4 under agro climatic conditions of Faisalabad, Pakistan.

Salt affected soils are characterized by high soil pH, excessive salts on the surface/in the rhizopshere and nutrition imbalance resulting in reduced crop productivity. Addition of organic amendments improves the physical condition and ultimately the crop growth. Field experiments were performed to assess the integrated nutrient management in moderately salt affected soil conditions using P-fixation capacity of soils in rice-wheat cropping system. Suitable site was selected to follow the rice-wheat rotation in permanent layout. Municipal solid waste compost (MSWC) was used as an organic source. Results revealed that combined application of MSWC with mineral fertilizer i.e., site specific use of mineral fertilizer with MSWC and integrated use of chemical fertilizers with MSWC in 80:20 ratio enhanced paddy/grain yield and improved the fertility status of the soil. The site specific integrated use of chemical fertilizer with MSWC in 80:20 ratio produced the highest biomass/paddy/wheat grain yield i.e., 8.48/2.55 and 5.43/2.58 Mg ha-1, respectively. Soil analysis was carried out before transplanting/sowing and after harvest of each crop. The pHs, ECe and SAR slightly reduced as compared to the initial values and this trend continued subsequently. Soil available P, organic matter, extractable K and Zn was enhanced especially in the site specific integrated use of chemical fertilizer with MSWC in 80:20 ratio. Minor increase in Co, Cu and Pb was observed with the application of MSWC in the treatments with integrated use of chemical fertilizers and site specific integrated use of chemical fertilizers with MSWC in 80:20 ratio. © 2015 Friends Science Publishers.

Chelated zinc fertilizers are usually recommended in calcareous alkaline soils to provide Zn nutrition in order to prevent possible Zn precipitation. In Punjab (Pakistan), Zn.EDTA products are being manufactured, and marketed to meet the zinc requirement of various crops grown in Zn deficient soils. Under fertilizer control order, 1973 (amended), their quality has to be monitored by the Agriculture Department, Government of the Punjab. None of the traditional method was found suitable which can separate the mineral fraction from that of chelated adulterated fertilizer except for those methods based on ion chromatography. Calibration of ion chromatography method was carried out by determining the mineral Zn fraction leading to estimate remaining Zn.EDTA fraction in fertilizer samples of adulterated nature i e. mixture of chelated and mineral fraction. In order to achieve the objective atomic absorption spectroscopy was coupled with ion chromatography. The method offers a specific, reliable technique for determination of chelated zinc in fertilizers. In the first step chelation was broken down with concentrated sulphuric acid treatment and total zinc contents were determined by atomic absorption spectroscopy. In second step, non-chelated (mineral) portion of zinc was determined by ion chromatography using cation column and conductivity detector. Chelated zinc was calculated by subtracting non-chelated (mineral) fraction from total zinc contents.

The effect of S application on soil sulfur (SO4-S) contents was investigated in different textured soils. The samples from eight soil series viz. Missa, Rajar, Qutbal, Guliana, Tirnaul, Rawal, Rawalpindi and Qazian of Pothwar area were collected and analyzed for physico chemical characteristics. Only two soil series i.e. Missa and Rajar had satisfactory (11-30 mg kg-1) S contents at upper soil depth while the rest were deficient (<10 mg kg-1) in sulphur. The highest SO4-S content (15.2 mg kg-1) was recorded in Missa soil, bearing clay loam, while lowest (5.4 mg kg-1) in Qazian soil bearing loamy sand soil texture at upper (0-15 cm) soil depths. The three soils deficient in SO4-S viz. Guliana, Rawal, Qazian, were selected for a pot experiment. Sulfur was applied @ 0, 5 and 15 kg S ha-1 using gypsum and ammonium sulphate (AS) as sources. The highest biomass (14090 kg ha-1) was observed with AS @ 15 kg S ha-1 application. The post harvest soil analysis revealed that the S application significantly increased soil SO4-S contents; the highest 9.49 mg kg-1 was observed where gypsum @ 30 kg S ha-1 was applied. The application of gypsum and AS @ 30 kg S ha-1 increased SO4-S contents by 8.5 and 7.60 % over control, respectively. The highest mean SO4-S contents (6.40 mg kg-1) were observed in Guliana soil having silt loam texture while lowest (4.64 mg kg-1) in Qazian soil. The results concluded that well drained, light textured soils in high rainfall areas have low SO4-S content and require S fertilization for optimum crop production. © 2010, Soil Science Society of Pakistan.

Different analytical procedures are being employed in the world to quantify the chelated portion in a Zn-EDTA fertilizer. Agriculture Department, Government of the Punjab is following Shahid́s analytical method in this regard. This method is based on Ion-chromatography (IC) that separates the mineral zinc (Zn) from an adulterated Zn-EDTA fertilizer sample i.e. mixture of mineral and chelated Zn fractions. To find out its effectiveness and suitability, this comparative study was carried out by analyzing adulterated, non-adulterated Zn-EDTA standard and Zn-EDTA samples taken from market in thrice following three methods namely Shahid́s (IC) analytical method, Atomic Absorption Spectrophotometric (AAS) method based on the principle of precipitating the mineral Zn fraction at high pH value by using alkali solution of suitable concentration and analysis of filtrate containing only chelated fraction and Association of Official Analytical Chemists (AOAC) method FM-841 respectively. Adulterated Zn-EDTA samples were prepared by mixing of known quantity of mineral Zn with chelated Zn-EDTA standard. The results showed that Shahid́s analytical method and AAS method, both successfully estimated the chelated fraction. The AOAC FM-841 method was insensitive to put a ceiling on the mineral fraction hence did not furnish the reliable results. The Shahid́s analytical method was selected being equally effective to produce reliable results both for solid and liquid Zn-EDTA samples. The AAS method was comparable in only liquid samples.

Soil characteristics of Chakwal district were evaluated through physical and chemical analyses. Representative soil samples received/collected from farmers fields were analyzed for texture, electrical conductivity (EC), pH, organic matter (SOM), available phosphorus (P) and potassium (K) contents. Texture of the soils varied from sandy loam to loam. About 97% soils had EC values within the normal range (< 4 dS m-1). The pH values of 64% soils ranged from 7.0 to 8.7 with an average of 7.9 and 6% soils had pH > 8.5. About 86% soils were poor in SOM and P, only 11% samples had satisfactory level of SOM (> 0.86%) and P (>7.0 mg kg-1) contents. The K status of most of soils (68%) was in satisfactory range. The frequency distribution indicated that most of the soils of Chakwal had SOM content in the range of 0.4-0.6%, P in the range of 2.1-4.0 and K in the range of 81-120 mgkg-1. The nutrient index values of Chakwal soils in respect of SOM and P were poor, whereas satisfactory for potassium. © 2012, Soil Science Society of Pakistan.

Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K ha-1 was applied as urea and murate of potash (MOP) respectively. Chemical composition of wheat plants showed that all the parameters were significantly improved by addition of P except the Phosphorus concentration (%) in wheat straw and potassium conc. (%) in wheat grain. Similarly Phosphorus uptake was increased with the increased level of phosphorus application. It was concluded from the study that different sources and levels of phosphorus has significant effect on the NPK contents of wheat and total P uptake by wheat plants. Among all the sources and levels of phosphorus, 80kg P ha-1 as single superphosphate (SSP) showed superiority over triple superphosphate (TSP), nitrophos (NP) and diammonium phosphate (DAP) on phosphorus deficient soil of Balkasr area of Tehsil Chakwal.

It can be said that the quality of the environment has become of increasing interest for many developed countries especially during the last one or two decades. It is important to know what has been the influence of human activity (especially industry, agriculture, etc.) upon the quality of the main components of the environment.Soil as one important part of the environment is more complicated as it includes organic and inorganic components and which involves comparing the monitoring with other environment components (i.e. monitoring of air, water, etc.).
