This study was conducted in six major apple growing areas of the Kargil region during 2009 and 2010; pheromone traps were evaluated for the monitoring and mass trapping of the codling moth. Monitoring the population dynamics of Cydia pomonella in 2009 revealed that the first catch was observed on 21 May, the highest on 11 June, and the lowest on 13 August at all of the locations. The dynamics were similar, but the population was lower in 2010. Climatic variables were more or less similar in both of the years. So, effective monitoring for the codling moth is essential and was highest in Hardas and lowest in Gongma during 2009 and highest in Shilikchey and lowest in Poyen in 2010. © , Copyright © Taylor & Francis Group, LLC.

Estimation of root water uptake and water movement in plants is crucial to quantify transpiration and hence the water exchange between land surface and atmosphere through plants. Present paper is aimed to illustrate and discuss how mathematical modeling can be used for understanding of plants and, in particular, plant-soil interactions. Soil water movement due to root water uptake is a key process for plant growth and transport of water in the soil plant system. There are different root water uptake models which can be used for estimation of moisture uptake by plants. The accuracy of moisture uptake prediction by plants depends on selection of proper mathematical models. Root uptake models are available in different forms i.e. linear, nonlinear, and exponential. In this paper, a detailed review of the most commonly used models which are suitable for the estimation of moisture uptake by plants in different agro-climatic regions is presented. Further, an effort has been made to compare the performance of different widely used models under controlled condition and future research needs are outlined. © 2014 © 2014 Indian Society for Hydraulics.

The present study was conducted to estimate the variation in herbaceous community features in terms of diversity, species richness and distribution pattern in the two different ecosystems i.e., site I (pastureland) and site II (forest) in the lower Dachigam National Park of Kashmir, Himalaya. The pasture site is located outside the National Park and is under grazing were as forest site is located inside the National Park and is protected. The study was done on seasonal basis and the results revealed higher trend for diversity(H') at both sites during summer season (site I = 3.03, site II =2.92). However, dominance index was inversely related to diversity index(H') (site I = 0.06 and site JJ = 0.07). Richness index showed maximum value in spring (4.12, site II) and summer (3.70, site I). Equability or evenness index obtained higher value in summer (0.94, site I) and winter (0.96, site II). Comparatively on an average site II showed higher trend in Shannon diversity (site I = 2.435, site II = 2.655), richness index (site I = 2.652, site II = 3.297) and equability index (site I = 0.852, site II = 0.915). The frequently occurred dominant species during prominent season based on IVT at site I were Cynodon dactylon, Salvia moorcroftiana and Thymus serphyllum at site II were Arthraxon prinoides, Fragaria nubicola, Poa annua, Poa sp. and Viola indica. The abundance to frequency ratio (A/F) indicated most of the species performed contiguous pattern of distribution. A seasonal picture depicted contagious> random distribution pattern while regular distribution was reported almost negligible. The study concluded that seasons have great influence on species diversity. During spring and summer season an increase in species diversity was observed which declined as autumn and winter approached mainly due to dry environmental conditions, slow growth rate and other climatic factors. © 2010 Asian Network for Scientific Information.

Soil water movement due to root water uptake is a key process for plant growth and transport of water in the soil plant system. The accuracy of prediction extraction rate by plants depends on selection of proper mathematical models. The water uptake by plant roots has been simulated both at the microscopic and macroscopic levels. The microscopic approach requires detailed information about the dynamic geometry of the plant root system that is practically not available. In the macroscopic approach, a sink term, representing water extraction by plant roots is included in the dynamic water flow equation and the spatial and temporal uptake is controlled by the soil moisture and the plant demand. Different pattern of moisture uptake including constant, linear and exponential are available in various models. Relevant literature points out that a non-linear, exponential and logarithmic macroscopic root water uptake model is popular due to their improved prediction efficiency. In this paper most commonly used models which are suitable for the estimation of moisture uptake by plants in different agro-climatic regions are reviewed and a field study of macroscopic model has been given. Model predicted soil-moisture parameters i.e., moisture depletion, moisture status at various depths and soil moisture profile in root zone are compared with experimental results. © 2013 Elsevier B.V.

Soil quality assessment provides a tool for evaluating the sustainability of soils under different crop cafeterias. Our objective was to develop the soil quality index for evaluating the soil quality indicators under different cropping systems in northwest Himalaya-India. Composite soil samples were taken from the study area from different cropping systems which include T1 (forest soil control), T2 (rice-oilseed, lower belts), T3 (rice-oilseed, higher belts), T4 (rice-oats), T5 (rice-fallow), T6 (maize-oats), T7 (maize-peas), T8 (apple), T9 (apple-beans), and T10 (apple-maize). Physical, chemical, and biological soil indicators were determined, and it was found that soil enzyme activities involved in nutrient cycling were significantly higher in forest soils, which were reflected in higher levels of available pool of nutrients. Carbon stocks were found significantly higher in forest soil which was translated in improved soil physical condition. Principal component analysis (PCA) was performed to reduce multidimensionality of data followed by scoring by homothetic transformation of the selected indicators. Pearsons interclass correlation was performed to avoid redundancy, and highly correlated variables were not retained. Inclusion of legumes in the apple orchard floor recorded highest soil quality rating across the treatments. Cereal-based cropping systems were found in lower soil quality rating; however, the incorporation of peas in the system improved soil health.

Pheromone traps with different doses of disparlure [(Z)-7,8-epoxy-2-methyloctadecane] were tested for a local strain of the Indian gypsy moth (Lymantria obfuscata) at Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir (India). Disparlure at 500 μg dose proved to be effective in trapping gypsy moth populations. The first adults were caught on the third week of June in 2007-2009 with peak catches a week later. Catches in disparlure-baited traps at all dosage levels (0.5, 50 and 500 μg) were significantly higher as compared to control traps. The regression equation revealed strong (99%) correlation between moth catches and applied doses. The accumulated degree day model predicted 65.31 to 117.97 heat units for larval hatch and 794.66 to 928.15 heat units for adult emergence. The principal component analysis showed significant variability between weather variables and adult L. obfuscata population. © 2015 Akadémiai Kiadó, Budapest.

Background & Objectives: Alloxan & streptozotocin are used for inducing diabetic models. Their combination has been used to reduce the individual chemical dosage and minimize the side effects. Present investigation was aimed at studying pre-diabetic clinical changes induced by low doses of Alloxan-STZ cocktail in rabbits. Materials and Methods: New Zealand White rabbits, 1-1.5 kg body weight, were administered alloxan (@50 mg/kg b.w.) and STZ (@ 35mg/kg b.w.) cocktail, as single intravenous dose. Blood glucose levels were monitored (0 h, 20 min, 1 h, and then hourly up to 9 h) and clinical signs noted. Rabbits surviving up to 9 hours were given glucose therapy. Results: The cocktail caused immediate transient hypoglycaemia, followed by hyperglycaemia, and then progressively severe hypoglycaemia. Hypoglycaemia caused characteristic behavioural alterations from lethargy, through aesthesia, muscular weakness to recumbency. Severely affected rabbits revealed intermittent convulsions and died in coma. Conclusion: Low dose Alloxan-STZ cocktail induced triphasic immediate response in rabbits. The behavioural changes reflected glycaemic status serving as a guide for institution of glucose therapy.

Chilli is an important cash crop and India is the largest grower, consumer and exporter of dry chillies and other products to over 90 countries around the world. This crop suffers heavy losses in yield due to many diseases especially dieback and fruit rot diseases the frequent epiphytotics of the diseases in the Kashmir valley. During the past few years and extend of damage infelicated necessitated us to generate basic information on the important aspects like status, variability, hostrang and integrated management of the disease. Thus, the present study was undertaken to know the behavior of the disease and biology of the pathogen so as to device better managemental practices of the diseases to avoid losses. The objectives of the study were carried out as per the latest methodologies adopted by various workers in the world. Pathogenic behavior of twenty isolates of C.capsici, developed from fruits of chilli, was established following Koch's Postulates. Colonies varied in their cultural behavior ranging from cottony to fluffy, mostly suppressed with regular to irregular margins. Colour of colonies ranged between white to grey. Growth rate of isolates was between 32.0-67.5 mm. Morphological studies of isolates revealed variations in their colour, size, shape, acervuli production, setae size and shape, conidia. Average conidial size varied from 2.23-33.6 μm and average setae size varied from 4.48-177.21 μm. On the basis of disease reaction expressed by differential hosts, ten groups (races) of C. capsici were identified. The group 1 comprised of isolates Cc-1, Cc-15 whereas group 2 included the isolate Cc-2, Cc-6, Cc-16. The Cc-3, Cc-10 were included in group-3 whereas group-4 included the isolate Cc-18, Cc-20, Cc-12, Cc-9. The group 5 comprised of isolates Cc-13, Cc-14. The group 6 comprised of Cc-17, Cc-19. The group 7 comprised of isolates Cc-5, Cc-11. Similarly, the isolate Cc-7 was clubbed under group 8. © 2013 Academic Journals Inc.
