Pedological characterization of soils is key for land resource planning and development of soil management interventions for improving agricultural productivity. A study was conducted in University Farm to examine soil morphological, physical and chemical attributes for land use planning and determining area specific soil management strategies. A detailed soil survey was conducted using a free survey method. Three profile pits were dug at the upper, middle and lower slope positions. Hoe and hand trowel was used in collecting soil samples from identified genetic horizons. The collected soil samples were then air-dried, crushed gently and stored in well labeled polythene bags. The processed soil samples were then taken to the laboratory for analysis following standard procedure to determine the physical and chemical properties of each soil sample. The results indicated that the soils are deep to very deep and most of the soils are predominantly weak-red to pale-red in colour (7.5R 4/3 – 10R 7/3), while soil structure is observed to be dominantly sub-angular blocky in all the profiles. The dry, moist and wet consistencies across slope were predominantly hard soft, friable, non-sticky non plastic, slightly sticky and slightly plastic respectively. The result of the soil particle size distribution indicated that the values of sand, silt and clay ranged from 17.6% to 69.6% (mean=46.26%), 6.40% to 64.4% (mean=39.3%) and 12% to 26% (mean=16.43%) respectively. The soils were generally found to be sandy loamy to silty-loamy in texture, while bulk density value was found to be low ranging from 1.19 to 1.66g/cm3. The mean pH ranged from 5.52 – 5.73 and termed to be moderately acidic in reaction. The mean organic carbon, total nitrogen and available phosphorus content obtained in this study ranged from 0.27 – 0.33mg/kg ,0.02 - 0.03g/kg and 6.82 – 6.94mg/kg respectively. The exchangeable bases (Ca, Mg, K and Na) were generally found to be medium to high. Management practices....

Improving water use efficiency is a vital strategy for addressing future water scarcity. Irrigation is a wide-ranging practice using every drop of water for crop production through suitable practices. Since irrigation plays a key role in global water availability by impacting water productivity, a field experiment was conducted in DL3 agro ecological region during the yala season of 2018 using drip and basin irrigation methods to evaluate the effect of deficit irrigation practices on growth, yield and water use efficiency of onion. Four treatments; water application through drip irrigation at 150%, 100% and 70% of crop water requirement and basin irrigation as control were designed. Water application at 100% of crop water requirement gave significantly higher onion yield as compared to 70% of crop water requirement and basin irrigation treatment. Also yield from 70% of water application and basin was not significantly different. The onion irrigated at 100% recorded 22.3% of increase in yield over basin method of irrigation. But, irrigation water use efficiency was found highest with drip irrigation at 70% of water application and lowest with basin irrigation. The amount of water saved at 150%, 100% and 70% under drip method was 13.8%, 31.12% and 50.8% respectively over basin method and this would be sufficient to irrigate additional area of onion crop earning better economic returns as compared to basin irrigation method. When consider the irrigation water use efficiency 70% of water application was the best irrigation practice compared to basin irrigation. Hence, the study suggests farmers in the dry region having limited amount of water for irrigation, should adopt drip method with combination of deficit irrigation rather than practice of basin irrigation methods.

This study was aimed to investigate the immunostimulatory and hepatoprotective effects of different levels of herbs extracts like Withania somnifera, Liquorice,Alium sativum and Berberis lycium used to investigate the improvement in immunity and liver function at Agricultural University Peshawar, Pakistan. For this experiment two hundred and forty (240) chicks were randomly assigned in to four major groups A, B, C and D. Each group was further divided in to two sub-groups. Each subgroup was replicated three times carrying 10 chicks per replicate. One of the subgroups was vaccinated against ND (New castle disease), IB (Infectious bronchitis) and IBD (Infectious Bursal disease) according to schedule.Group A was kept as control, while B, C and D were treated with Withania somnifera , Licorice, Alium sativum and Berberis lycium extract at the rate of (5gms + 2.5gms + 2gms + 8gms), (10gms + 5gms + 3gms + 9gms), (15gms + 7.5gms + 4gms + 10gms) gm/lit of water respectively. AST (Aspartate amino transfarase) and ALT (Alanine amino transfarase)was significantly (P<0.05) reduced in group B than rest of the groups, while serum protein and alkaline Phosphatase was significantly (P<0.05) affected in group B as compared with other groups. Chicks were reared in cages in an open sided house. The data was recorded for immunostimulant and hepatoprotective effect. ND, IBD and IB was significant (P<0.05) higher in group B.It is concluded that Withania somnifera, Licorice, Alium sativum and Berberis lycium) extract @ of (10gms + 5gms + 3gms + 9gms) gm/L of water could be effectively utilized to improve immunity and liver function.
