Agro-forestry is as relevent, meaningful and useful for Bay Islands as it is for any other part of country. Climate, topography, accessibility and cultivation condition of the islands are different than the rest of the country and so are the agro-forestry systems and some of them are quite specific to the islands. Large natural forest area, climate, topography, accessibility, local needs and land holding conditions strongly influence on fitness of agro-forestry systems for the islands. Suitable tree, shrub and herb species for different agro-forestry systems are mentioned.

This paper deals with the estimation of uncertainty of viscosity measurement of an epoxy-anhydride mix by Analog Brook Field Viscometer in line with the requirements of ISO 17025: 2005. The different factors as listed below contributing uncertainty in the viscosity measurement have been identified and total uncertainty of viscosity measurement by Brookfield Viscometer has been estimated.
1. Type A component of uncertainty
2. Type B component of uncertainty attributed to the following factors:
a. Uncertainty reported in the calibration certificate of the viscometer
b. Uncertainty arising from the accuracy and precision of Brook Field Viscometer.
c. Uncertainty arising from the variation of temperature during viscosity measurement
The expended uncertainty obtained in the viscosity measurement of the epoxyanhydride mix is 1.84 cP at a coverage factor 1.96 which for normal distribution corresponds to approximately 95% confidence level.

The Calcium oxide crystal possesses well developed structure of the NaCl-type and is divalent in nature. Oxides and silicates make up the bulk of the Earth's mantle and crust, and thus it is important to predict their behaviour. The elastic energy density for a deformed crystal can be expanded as a power series of strains using Taylor's series expansion. One can get this expansion starting from nearest neighbour distance and hardness parameter utilizing Coulomb and Born-Mayer potentials for face centred cubic crystal symmetry. The coefficients of the quadratic, cubic and quartic terms are known as the second, third and fourth order elastic constants (SOECs, TOECs and FOECs) respectively. When the values of second and third order elastic constants and density for any material at a particular temperature are known; one may get ultrasonic velocities for longitudinal and shear waves in different crystallographic directions which give important information about its anharmonic properties.The theory obtained is applied to get the higher order elastic constants for Calcium oxide crystal at different higher temperatures and the results obtained are presented graphically and discussed widely.

The efficacy of three bio-control agents viz., Trichoderma viride, Trichoderma harzianum and Pseudomonas fluorescens were evaluated against downy mildew of pearl millet in glasshouse as well as in field conditions at research farm, Rajasthan Agricultural Research Institute, Durgapura (Jaipur) during cropping seasons of kharif 2016 and 2017. The seed treatment with Trichoderma viride (@ 6 g/kg seed) followed by one spray of Pseudomonas fluorescens (@ 1 x 108 cfu/ml) 21 days after sowing significantly reduced the downy mildew incidence and increased the grain and fodder yield. Seed treatment with Trichoderma harzianum followed by one spray of Pseudomonas fluorescens (@ 1 x 108 cfu/ml) 21 days after sowing were the next in reducing the downy mildew incidence at significant level.Keywords
