The experiment was laid out in factorial randomized complete block design with three replications. The treatment consisted of six foliar dozes viz. T 1 (Tap water as control), T 2 (0.10 % urea), T 3 (0.25 % urea), T 4 (0.40 % urea), T 5 (5 ppm planofix) and T 6 (10 ppm planofix) and three application frequencies viz. F 1 [20 days after sowing (20 DAS)], F 2 (30 DAS) and F 3 (20 and 30 DAS). Maximum foliage yield (6.94 t/ha) was recorded in 10 ppm planofix coupled with it’s twice application at 20 and 30 DAS which was closely followed the foliage yield (6.33 t/ha) by 5 ppm planofix with the same application frequency. The foliage yield was increased with the increase in urea concentration. The highest foliage yield (5.37 t/ha) was also recorded from twice application of urea and planofix at 20 and 30 DAS, respectively. Planofix 10 ppm with its twice application at 20 and 30 DAS gave the highest benefit-cost of ration 2.51. Int. J. Agril. Res. Innov. & Tech. 5 (1): 40-44, June, 2015
Effect of seed treatment and foliar spray of thiourea on growth, yield and quality of coriander (Coriandrum sativum L.) under different irrigation levels
A field experiment was conducted during the rabi 2011-2012 at research farm, College of Horticulture, Mandsaur (Madhya Pradesh) to study the effect of seed treatment and foliar spray of thiourea on growth, yield and quality of coriander (Coriandrum sativum L.) under different irrigation levels. The experiment consist three irrigation levels (in main plots) viz., (I 1 -one, I 2 -three and I 3 -six irrigations) and six thiourea treatments (in sub plots) viz., (T 1 -Control, T 2 -Thiourea 500 ppm seed treatment for 4 hours, T 3 -Thiourea 1000 ppm seed treatment for 4 hours, T 4 -Thiourea 500 ppm foliar spray at vegetative and flowering stages, T 5 -Thiourea 500 ppm seed treatment for 4 hours + Thiourea 500 ppm foliar spray at vegetative and flowering stages and T 6 -Thiourea 1000 ppm seed treatment for 4 hours + Thiourea 1000 ppm. foliar spray at vegetative and flowering stages). Both irrigation levels and thiourea treatments significantly influenced the growth, yield and quality attributes of coriander. Irrigation level I 3 and thiourea treatment T 6 resulted in significant higher plant height at 90 DAS, number of branches plant -1 , fresh weight of leaves plant -1 , dry weight of leaves plant -1, days taken to harvest, number of umbels plant -1 , number of umbellets umbel -1 , number of seeds umbel -1 , test weight, seed yield, straw yield, biological yield, chlorophyll content of leaves, essential oil content of seeds and net return. However days to 50 % flowering was non significantly affected by thiourea treatments. Maximum harvest index and cost: benefit ratio was also found with Irrigation level I 3 and thiourea treatment T 6.
Genotypic diversity in field isolates of Babesia bovis from cattle with babesiosis after vaccination.
OBJECTIVE
To determine whether particular genotypes of Babesia bovis were common to field isolates obtained from cattle properties in Queensland where the B bovis vaccine had apparently failed.


DESIGN
A comparative study of polymerase chain reaction genotypes in different populations of B bovis.


PROCEDURE
Two polymerase chain reaction assays were applied to analyse DNA extracts of B bovis vaccine (K, T and Dixie strains) and 27 field isolates from 24 properties where disease outbreaks had occurred despite the use of the vaccine. To evaluate the stability of the genotypes identified, 11 of the field isolates were inoculated into experimental cattle that had either been previously vaccinated with T strain or not vaccinated.


RESULTS
No particular genotype of B bovis was responsible for the problems observed in previously vaccinated herds. None of the isolates had genotypes identical to the vaccine strains used. No geographic trends among the genotypes were observed. Isolates that originated from the same property also had different genotypes. Blood passage of the 11 field isolates in either previously vaccinated or nonvaccinated cattle did not alter the original genotype.


CONCLUSION
No particular genotypes identified by the Bv80 and BvVA1 polymerase chain reaction assays could be associated with vaccine failures.
