  The mechanism of "seed to seedling infection" of blight disease caused by Ascochyta rabiei (Pass.) Lab., was studied while growing naturally infected chickpea seeds and healthy seeds artificially inoculated with pathogen inoculum. The disease symptoms appeared on young seedlings within a week after emerging from soil. The seedling infection was due to contact of growing point to the pathogen inoculum from infected seeds during the process of shoot differentiation under the ground. Based on the observations of disease symptoms on the seedlings from contaminated seeds, it is concluded that contamination of plumule with pathogen inoculum during germination appears to be a major mechanism by which the pathogen transmission occurs on aerial parts of the plants.

  Concerns over increased phosphorus (P) application with nitrogen (N)-based compost application have shifted the trend to P-based composed application, but focusing on one or two nutritional elements does not serve the goals of sustainable agriculture. The need to understand the nutrient release and uptake from different composts has been further aggravated by the use of saline irrigation water in the recent scenario of fresh water shortage. Therefore, we evaluated the leachability and phytoavailability of P, N, and K from a sandy loam soil amended with animal, poultry, and sludge composts when applied on a total P–equivalent basis (200 kg ha–1) under Cl (NaCl)- and SO42– (Na2SO4)-dominated irrigation water. Our results showed that the concentration of dissolved reactive P (DRP) was higher in leachates under SO42– than Cl treatments. Compost amendments differed for DRP leaching in the following pattern: sludge > animal > poultry > control. Maize (Zea mays L.) growth and P uptake were severely suppressed under Cl irrigation compared with SO42– and non-saline treatments. All composts were applied on a total P–equivalent basis, but maximum plant (shoot + root) P uptake was observed under sludge compost amendment (73.4 mg DW–1), followed by poultry (39.3 mg DW–1), animal (15.0 mg DW–1), and control (1.2 mg DW–1) treatment. Results of this study reveal that irrigation water dominated by SO42– has greater ability to replace/leach P, other anions (NO3), and cations (K+). Variability in P release from different bio-composts applied on a total P–equivalent basis suggested that P availability is highly dependent on compost source.

  Leeching has enjoyed a good reputation in the past where it had been used in various ailments from fevers to flatulence. The present day scientists have limited its role and the leeching nowadays is being used only in microsurgeries to relieve the venous congestion. This study was designed to explore the possibility of revival of the leech therapy (leeching) which is still being used traditionally as therapeutic agent in various ailments. Leeching is not the outcome of the medieval period but has been in use during the times when there was no concept of the disease and medicament. The earliest clearly documented record of leeches being used for remedial purpose appears in a painting in an Egyptian Tomb of around 1500 BC. The journey of the leech therapy reached its zenith in 17th and 18th century AD in Europe while as during the Arab era the leeches were used medicinally but only for the bloodletting. During the 17th and 18th century AD there was shortage of leeches in certain European countries due to its rigorous use. During early 20th century AD when germ theory was put forward and medical fraternity believed that every disease has its origin from germs and the era of antibacterial therapy gained a pace, the leech therapy was considered the myth of the past. It was in 1970`s that the leech therapy was revived by only limited to the microsurgeries to relieve venous congestions. During the 21st century there were certain studies when the leeches were tried in certain ailments like arthritis etc. and the Food and Drug Authority of USA (FDA) gave permission for sale and use of leeches in USA but limited its use in microsurgeries and plastic surgeries only. The aim of this study was to explore different diseases where the role of leech therapy can be seen and clinical trials can be started in this direction. Although the researchers in Regional Research Institute of Unani Medicine, Srinagar, Kashmir, India working under the aegis of Central Council for Research in Unani Medicine started the clinical trials for leech therapy in frost bite way back in 1999, but there are certain unexplored areas where leech therapy can prove beneficial and need is to take up the studies on other disease on larger sample size.

  Tropical fodder legumes not only provide superior fodder but also increase the soil fertility due to nitrogen fixing bacteria. For production of fodder during summer, three exotic fodder species, Lablab purpureus, Vigna umbellata and Macroptilium lathyriodes imported from Plant Introduction Station of U.S.A. were evaluated for quality and yield. These crop species were observed carefully and described morphologically. Herbage yield was more than cowpea and significant among all the species, hence could be used as forage crop. Crude protein, ether extract and crude fibre were higher in Macroptilium, whereas herbage yield was significantly higher in lablab bean. Correlation coefficients were different for various crop species which revealed that improvement might be possible through collection and selection for desirable traits, especially in lablab bean which exhibited high correlation between herbage yield and quality characters.

  Very few studies have been conducted regarding the role of diet in the disease activity in joint disorders. None of such studies have been conducted so far in this direction in Asian countries in general and in India in particular. The objective of the study was to see the influence of the diet and fasting on the disease activity in musculoskeletal disorders. The possible influence of diet on chronic arthritis is difficult and controversial issue. A number of epidemiological studies have examined the role of diet in the aetiology of rheumatoid arthritis. Many patients with arthritis believe that diet has an influence on disease activity and report the aggravation of symptoms associated with certain diets. The study was a questionnaire based survey of the patients with joint disorders who attended the Out Patients Department of Regional Research Institute of Unani Medicine, Srinagar Kashmir India. The survey was conducted on 100 patients consisting of 85% osteoarthritis patients and 15% rheumatoid arthritis patients. The 80% of rheumatoid arthritis patients believed that diet has some role in disease activity and 53% of osteoarthritis patients believed the aggravation of symptoms with certain diets. On the whole red meat was found to be major constituent of diet which aggravated the symptoms in 80% of rheumatoid arthritis patients and 41.1% osteoarthritis patients. Influence of fasting during the month of Ramadan was also recorded and it was observed that 61% of rheumatoid arthritis patients had relief during fast while as 49.3% of osteoarthritis patients had relief in symptoms during the fasting. The details are discussed in the paper. It is concluded that certain diets have definite role to play on the disease activity in joint disorders and fasting has some effect on the severity of the disease.

  A study was conducted at Livestock Research and Development Station, Animal Analytical Laboratory Dir Lower Khyber Pakhtunkhwa (KPK) Pakistan to document the phenotypic and Morphometric characteristic of Achai cattle. Total 18 pure Achai Cattle were selected in the study. Phenotypic characteristic were recorded visually. Majority (88.50%) of the study Achai color have reddish brown coat color with white face but those animals were also included in the study that have radish brown color with or without white spotted face, gray muzzle, radish and white eye lashes. Physical characteristic (color of coat, muzzle, face, eye lash, horns, hump, udder hooves and tail switch) were recorded visually while morpho-metric measurements (heart girth, body length, height at withers, horn length, ear length, neck length, hoof circumference and tail length) were recorded by using measuring tape and vernier caliper. Mean body, face, ear, horn, rump and tail length was 112±4.78, 42±0.502, 19±0.469, 17±0.874, 33±0.481 and 75±1.332 centimeter, respectively. Mean width of head and shoulder was 12±2.937 and 89±0.2711, respectively. Mean circumference of neck and abdominal was 68±1.03 and 168±2.159. Mean chest girth was 142±0.978 and rump height was observed 103±4.16 accordingly. The average body weight of adult Achai cow recorded was 203.81±6.17 kg. The average birth and weaning weight was recorded 13.90±0.80 and 48.0±5.00 kg, respectively. It was concluded that Achai is a small size breed of Khyber Pakhtunkhwa Pakistan having short stature, radish brown color and fully adapted to the hilly areas of the province.
