Journal of Biological Sciences , 2001,
Abstract: The present studies were made on the performance of six imported cultivars and one local selection of almond strain at the Horticultural Research Station, Soan Valley Nowshera, Khushab during 1997 to 1999. Local selection almond strain gave a little earlier bloom while all other cultivars were late. However, all tested cultivars matured at the same time during second week of July. Jordonela, Non-perial, Neplus-Ultra, Vesta and Mission are thin shelled while local selection kernel percentage were produced by Jordonela and minimum in Mission and local selection. Is medium thick shell. Maximum nut length, nut thickness, kernel length, kernel weight and kernel percentage were produced by Jordenela and minimum in Mission and local selection. Yield in terms of number of fruit per tree and nut weight per tree was maximum in Nepus-Ultra followed by Non-Perial and Jordonola. Kernel breadth was maximum in Mission. On the basis of overall performance, qualitatively Jordonola performed the best and quantitatively Nepus-Ultra and Non-perial were found better.

Journal of Biological Sciences , 2001,
Abstract: The present studies were carried out on four walnut cultivars viz Hartley, Payne, Sorrento and Odom at the Hill Fruit Research Sub-Station, Lower Topa, Murree during 1999-2000. Vigorous plants were noted of Odom cultivar. Similarly Odom nuts were significantly larger in size having 36.70 mm length and 35.65 mm diameter as compared to the minimum size (29.50 mm length x 27.54 mm diameter) in cv. Sorrento. Weight of the fruit kernel and kernel percentage was maximum in Odom and minimum in Payne. Nuts of Odom cv. Mature in the first week of October while all other cultivars in second week of October Significantly highest number of fruits/tree (205) and weight (2.07 Kg) was attained in Odom and least in other cultivars. Conclusively Odom cultivar of walnut is recommended fro early maturity, large and heavy fruit and the maximum yield.
Effect of Chemical Fertilizers in Combination with Manure on the Physico-chemical Characters of Loquat at Lower Altitude of Murree Hills
Muhammad Akram Nasir,Shafqat Ali Syed,Muhammad Afzal,Shakeel Ahmed
Journal of Biological Sciences , 2001,
Abstract: During 1997, maximum weight of the fruit (16.46 g), weight of flesh (14.46 g), seed size in length and diameter (1.81x1.30 cm) and least acidity (0.65 %) was observed in the fruit obtained from the trees which were applied with nitrogen in combination with phosphorus and potash. The trees where no fertilizer was applied, produced the smallest fruit of low quality. The use of potash has significantly reduced the acidity of pulp. But the fertilizer could not affect the T.S.S. contents. Whereas, during the year 1998, the fertilizers significantly increased the T.S.S. contents against untreated plants. Hence, 1 kg of nitrogen in combination with 0.75 Kg phosphorus and 0.50 Kg potassium alongwith 40 Kg of F.Y.M. per tree is recommended for full grown loquat plants.
Role of Canal Lining on Groundwater Fluctuations: A Modeling Simulation Approach for Jaalwala Distributary, Bahawalnagar  [PDF]
Muhammad Hammad Atique Khan, Muhammad Usman Saleem, Sajid Rashid Ahmad, Nasir Ahmad, Shahid Jamil Sameeni, Muhammad Akram, Muhammad Farooq
Open Journal of Applied Sciences (OJAppS) , 2017, DOI: 10.4236/ojapps.2017.75019
Abstract: Jaalwala Distributary was selected to see the consequences of concrete lining on the underlying saline groundwater table. Its middle and tail portions were concrete lined whereas the head portion was still unlined. Visual MODFLOW 2011.1 was used to simulate the effects of concrete lining on saline groundwater in two-dimensional format. Simulation results showed a gradual rise of electrical conductivity (EC) up to 7000 μS/cm and decline in water table depth to nine feet (2.74 m). It observed negligible inflows from the distributary through its western boundary due to formation of a permanent barrier in the way of seepage of any kind. Results have further predicted that freshwater layer available beneath the Jaalwala Distributary (before its lining) will finish ultimately and the below present saline water also move upward to take this vacated place. Hence it was concluded to line the canals of saline water areas from their sides which will not only protect them from erosion but canal water theft as well.
Standardization of rootstock for almond propagation in pothohar area
Muhammad Akram,Nasir M.Z. Nawaz,A. Baksh,M.A. Summrah
Pakistan Journal of Biological Sciences , 2000,
Abstract: This experiment was conducted at the Horticulture Research Station, Noeshera, Soany Valley, Khushab during 1997-98. Various rootstocks viz, Wild apricot (Hari), peach and almond were tested for almond scion on the basis of their effect on grafting success, scion thickness, stock thickness and height of grafted plants. Maximum grafting success (69.33) stock and scion girths (4.35 and 4.07), plant height (45.0 cm) when almond scion was grafted on almond stock during 1997. Almost similar trend was noted during 1998. However, peach rootstock performed better than Hari rootstock during both years. Conclusively almond rootstock is recommended for almond propagation in the Pothohar tract.
Performance of Some Early Maturing Apple Cultivars at High Altitude of Murree Hills
Muhammad Akram Nasir,Attiq Akhtar,Shakil Ahmad,Hafiz Riaz Ali Shah
Journal of Biological Sciences , 2001,
Abstract: The present studies were carried out on four high chilling early maturing cultivars viz. Saharni, Beauty of Bath, Early McIntosh and Loxton Epicure at Hill Fruit Research Station, Sunny Bank, Murree during 1990-2000. Early McIntosh fruits were significantly larger in size index (62.28) as compared to minimum size index (55.12) in Loxton Epicure. Fruit weight was maximum (108.12 gm) again in early McIntosh and minimum (74.98 gm) in Loxton Epicure. All the cultivars bloom at the same time during the second week of April. However Loxton Epicure mature early as compared to other cultivars. Significantly highest number of fruit/tree (352) and weight (26.39 kg) was attained by Loxton Epicure and least in other cultivars except Early McIntosh which was at par to Loxton Epicure. Maximum TSS were noted in Saharni and Early McIntosh while minimum in Loxton Epicure and Beanty of Bath. All other cultivars were attractive in colour with sweet aromatic taste except Loxton Epicure which was acidic. Although Loxton Epicure, McIntosh and Beauty of Bath gave more production but Saharni is recommended for attractive colour and sweet aromatic laste.

Irfan Hafeez, Saqib Nasir, Samreen Zahra, Muhammad Aamir, Zahid Mahmood, Adnan Akram
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2017, DOI: 10.4236/jmmce.2017.51004
Abstract: A rapid and simple process has been developed for the recovery of antimony metal from stibnite ore of Kharan area (Balochistan) of Pakistan. The ore was characterized by X-ray diffraction (XRD) technique and found to contain 66% stibnite i.e. antimony sulfide (Sb2S3). The process parameters for the extraction of antimony were optimized on laboratory scale by varying reaction temperature from 900 - 1000, reaction time from 20 - 80 minutes and flux concentration was varied from 5 - 25 weight percent of the reaction mixture. The metal thus recovered with optimum conditions was evaluated by X-ray fluorescence (XRF) technique and was found to be more than 94% pure. The recovery yield calculated on the basis of stibnite present in the ore was 98.52%.
