In the present study, fumonisin B1 (200 ppm) and ochratoxin A (2 ppm) were fed alone and in combination to day old Japanese quail chicks for 21 days to evaluate renal ultrastructural changes. The severity and intensity of renal ultrastructural changes varied with the type of treatment, and predominant and consistent lesions were found in the proximal convoluted tubule (PCT) lining cells. Distortion and dilatation of cisternae of endoplasmic reticulum leading to the formation of vesicular and tubular structures was a consistent finding noticed in the fumonisin B1-fed group. Ochratoxin A treatment revealed characteristic changes in the epithelial brush border of PCTs with blunting and variable loss of microvilli. Reduced number of mitochondria with mitochondrial pleomorphism (round, oval, curved, elongated, dumbbell, banana, pear, and tennis racket) was almost a consistent finding noticed in the ochratoxin A treatment group. Ultrastructural changes in the combination fed group were almost similar to those noticed in the individual treatment groups but were of a higher intensity. Or in other words, we can say that on simultaneous exposure, fumonisin B1 potentiated the toxic effects of OTA on renal ultrastructure. © 2012 Springer-Verlag London Limited.

This paper outline the indigenous technical knowledge (ITK) possessed by farmers of Kathua district of Jammu & Kashmir, India, which is largely dependent on the traditional/indigenous animal husbandry practices for treatment of animals. The study was aimed to document various ITKs related to healthcare management of dairy animals and to validate the ITKs practiced for pneumonia treatment. Data were collected through personal interviews and focus group discussions with selected group of the Dogra, Gujjars and Bakarwals community members. Altogether 25 plants were recorded which are used by the local people in formulation of different traditional medicines for curing 20 types of livestock diseases and ailments. Validation of ITKs was done through Quantification of Indigenous Knowledge (QuIK) method developed by Anne K de Villiers (1996). The Indigenous practices for pneumonia treatment were perceived better than Modern Veterinary Drug (MVD) due to ease in availability, less side effects and low cost. The potential of herbal plants validated in this study can be taken up for experimental validation and concerted efforts are called for conservation of such plants. © 2016, National Institute of Science Communication and Information Resources (NISCAIR).

A tractor operated, three point hitch mounted cotton precision planter was developed for variable rate application of fertilizers at different depths along rows of seed placement. The developed planter creates two bands (each 25 cm wide) of tilled soil at 67.5 cm centre to centre distance by rotary tillage. It is capable of placing fertilizers in variable proportions and depths of placement in each band of tilled soil. The fertilizer application on both sides of a crop row always remains constant. After fertilizer placement the tilled band of soil is leveled and is followed by seed placement at the centre of tilled band by an inclined plate metering mechanism ensuring that two water soaked cotton seeds are dropped per hill. The plant spacing has been set at 90 cm. All these operations were completed in single pass operation. The planting with the planter resulted in to significantly higher germinated hills over manual planting. There was overall 15.01% increase in germinated hills with planting with precision planter in comparison with manual planting. The field capacity and fuel consumption were in the range of 0.36 to 0.37 ha/h and 3.89 to 4.28 l/h, respectively. An experiment on planting with precision cotton planter for placement of fertilizer at different depths and proportions comprising of seven treatments (i.e. placement of 70% of fertilizers at 15 cm & 30% at 25 cm depths; placement of 50% of fertilizers at 15 cm & 50% at 25 cm depths; placement of 70% of fertilizers at 10 cm & 30% at 20 cm depths; placement of 50% at 10cm & 50% at 20 cm depths, placement of 100% of fertilizers at 10 cm depths; placement of 100% of fertilizers at 15 cm depth and broadcasting of 100% of fertilizers) were conducted at two locations The placement of 70 and 30% of the recommended fertilizer at 10 and 20 cm depths, respectively gave significantly high seed cotton yield (27.37 q/ha) than manual planting with broadcasting of fertilizer (22.99 q/ha).

There is continuing need to develop improved cultivars with traits that can be determined in various generations. To identify traits that can facilitate selection of productive progenies in late-segregating generations, elite F5 progenies of okra [Abelmoschus esculentus (L.) Moench] along with the open-pollinated variety Varsha Uphar were investigated for the extent of genetic variability and correlation among various characters related to fruit and seed yield. Number of fruit, average fruit weight, fruit length, and internodal distance were important for developing genotypes for higher fresh fruit yield. For high seed yield, genotype-pertinent characters were average fruit weight, fruit length, seed number/fruit, seed weight/fruit, 100 seed weight, and shelling percentage. Most characters exhibited moderate heritability, indicating that high fresh fruit and seed yields can be selected through simple selection but not with high reliability in okra. Number of branches/plant, internodal distance, numbers of seed/fruit, stalk length, and fresh fruit yield confer the preponderance of variation that needs to be considered in late-generation selection in okra. Yield characters, number of fruits/plant, fruit length, and average fruit weight were major contributors to fresh fruit yield. For seed yield increase, fruit number, dry fruit weight, number of seed/fruit, and 100 seed weight were associated and need to be considered in developing genotypes for higher seed yield. © 2012 Copyright Taylor and Francis Group, LLC.

The effect of soil solarization on physical, chemical and biological properties of soil was studied, along with the response of cauliflower seedlings following solarization. Nursery beds were covered with transparent polyethylene sheet and soil temperature and moisture were recorded. Soil samples were collected five times for analysis. Three cauliflower nurseries were raised at 30-day intervals; germination was recorded 10 days after sowing and seedling length 30 days after sowing. The maximum temperature in solarized soil ranged from 40.2-47.2°C, with an increase of 5.2° to 9.9°C over non-solarized soil. There was a conservation of 5.48% moisture in solarized soil as compared with non-solarized. Solarization significantly increased electrical conductivity, organic carbon, nitrogen and potassium over pre-solarized soil. The mean pH, EC, Ca, Mg, N, P, K and C recorded in solarized soil was higher than in non-solarized. Soil solarization reduced the population of fungi from 25.68 x 104 to 4.8 x 104, bacteria from 20.28 x 106 to 5.66 x 106, actinomycetes from 31.60 x 105 to 4.40 x 105, and reduction in population was recorded even after 90 days, when compared with non-solarized soil. Solarization effectively reduced (>97%) population of plant parasitic and free living nematodes. Cauliflower seedlings in solarized soil had a better vigor index than non-solarized soil. Present findings reveal that soil solarization could be exploited for nutrient management and soilborne pests control, with a better vigor index of vegetable nursery. © 2013 Springer Science+Business Media Dordrecht.

The total phenol content, peroxidase and polyphenol oxidase enzyme activities and the total protein profile in tomato cultivars (Lycopersicon esculantum Mill.), tolerant and susceptible to Fusarium wilt disease was studied. The tolerant cultivars of tomato viz., FEB-2, FEB-4, FloraDade and NF-31 had significantly higher phenol content as well as peroxidase and polyphenol oxidase activities than the susceptible ones (Sel-7, Sel-18 and Punjab Chhuhara). The maximum peroxidase activity was recorded in the resistant cultivar, Flora Dade (02.073unit/ml) and minimum in the susceptible cultivar,Sel-18 (0.241unit/ml). Major differences in soluble protein banding pattern were observed in the susceptible and resistant cultivars. The hierarchical cluster analysis was performed using NTSYS-pc(V.1.8) software. The dendrogram using the average linkage between the groups, showed proximity of resistant cultivars viz., FEB-4,FEB-2, Flora Dade and NF-31 to the wild species with respect to similarity of banding patterns. The three susceptible cultivars viz., Sel-7, Punjab Chhuhara and Sel-18 were grouped separately.

Ten genetically diverse okra genotypes were taken for the present investigation. All possible single crosses excluding reciprocals were made among these parents and all the 10 parents and 45 F 1s were sown in a randomized block design with three replications. Observations recorded on quantitative traits showed considerable genetic variability. High heritability estimates were recorded for plant height, fruit width, fruit length, number of fruits per plant and weight of fruit per plant in both parents and F 1 generation. Genetic advance and genetic gain varied from 0.13 to 79.62 and 3.03 to 37.14, respectively. On the basis of correlation studies, fruit width was negatively correlated with fruit length (- 0.792) and positively correlated with weight of fruits per plant (0.662). Fruit length was positively correlated with weight of fruit per plant (0.703). Fruit width, fruit length, number of fruit per plant and weight of fruits per plant are most desirable characters, which affect the yield and such characters should be taken into consideration while making selection for overall improvement.

Pathomorphological alterations of chicken coccidiosis in Jammu division were undertaken in both organized and backyard chickens during the year 2010-2011. A total 240 intestines were examined from both organized farms and backyard chickens for histopathological studies. Out of 240 samples processed, 48 samples were found to be positive for coccidiosis with a prevalence of 20%. Coccidiosis was initially diagnosed on the basis of faecal examination and confirmed by the presence of sporulated oocysts and pathomorphological alterations in intestines. Eimeria species were identified by morphometry. Five Eimeria species identified were Eimeria tenella, E. necatrix, E. maxima, E. acervulina and E. mitis. Histopathological lesions revealed loss of epithelial tissue, congestion of blood vessels which indicate disruption followed by haemorrhage, severe muscular oedema and necrosis of submucosa of intestine and caecum. There was loss of intestinal villi, disruption of caecal mucosa and clusters of oocysts seen. There was massive infiltration by heterophils and mononuclear cells. Several merozoites, schizonts and microgametes were found in the epithelial cells.
