A field experiment was conducted during the Rabi season to find out the effect of organic manures, biofertilizers and micronutrients on growth, yield and quality of onion cv. NHRDF Red - 2. There were 13 treatments viz., T0 (Recommended dose of fertilizers), T1 Poultry manure, T2 vermicompost, T3 Azotobacter, T4 VAM, T5 Azotobacter+RDF (50%)+zinc, T6 Azotobacter+RDF(75%)+zinc, T7 VAM+RDF(50%)+boron, T8 VAM+RDF (75%)+boron, T9 RDF (25%)+VAM+poultry manure (50%)+Azotobacter+boron, T10 (RDF (25%)+VAM+vermicompost (50%)+Azotobacter+boron, T11 RDF (25%)+VAM+poultry manure (50%) Azotobacter+zinc, T12 RDF (25%)+VAM+vermicompost 50% Azotobacter+zinc and the experiment was laid out under RBD with three replications. The study clearly revealed that there were significant effects of various treatments on the growth, yield and quality attributes of onion. The number of leaves per plant (12.15), plant height (73.02cm), neck thickness (22.00mm), bulb length (6.46 cm), bulb diameter (7.20cm), yield (398.36 kg/ha-1) were recorded maximum in treatment T12 whereas T.S.S (14 °B), vitamin C (12.11mg/100g), total sugars (10.52%), reducing sugar (6.23%) and non-reducing sugar (4.28%) were found maximum in T10 treatment as compared to other treatment. However, T12 was good for higher yield improvement and T10 was the best for quality improvement among the all treatments under study, the application of T12 (RDF (25%)+VAM+Vermicompost 50% Azotobacter+Zinc) may be suggested for successful cultivation of onion in Lucknow.Keywords

Indian Rural Market has wide opportunities for emerging insurance sector This Research paper is a marl<et scan to seek opportunities of insurance sector in Potential Rural Indian market. This market Research was done in few Villages, near by Bikaner (Rajasthan) to find the opportunities of insurance sector in Rural Indian Ivlarket for upcoming years. Since the market has a very large population so research was done in 5 villages and 60 sample size was taken from each village. But on the other side this area has its own issues to deal with.
Issues involved in market research are to check awareness level of villagers about insurance, and to seek scope of growth for insurance sector in Indian rural market. Through this research it was tried to measure scope of penetration for insurance companies in rural market and strategies to promote insurance sector To capture rural market companies should understand the expectation and actual need of villagers as well as they should understand the emotions of villagers for long term succe

Advances in computer methods over the last two decades have accelerated research in engineering sectors because of high computing power. Micro-machining is a manufacturing domain that is widely utilized for producing miniature components where predictability is a concern. The current work emphasized developing and executing a user-defined constitutive flow and friction models to simulate the physical phenomenon of chip morphology, residual stresses, and cutting forces during orthogonal machining at the micro-scale. The proposed model integrates strain gradient and dynamic recrystallization effect using a user hardening subroutine written in Fortran for machining of Ti-6Al-4V in micron scale. Furthermore, a user defined friction subroutine was implemented at the tool-chip interaction. A comparison is made between the modelling results and experiments in terms of specific cutting energy (SCE) and residual stresses.Keywords
