Broccoli (Brassica oleracea L.) is an important winter vegetable under the cole groups, which has great market potential in India and Gulf countries. The climatic condition of Terai region of West Bengal is highly suitable for broccoli cultivation that argued for the possibility of getting more net profit of the farmers from cultivation of this high valued crop. But due to the micronutrient deficiency in the soil of terai region, broccoli not gives good return for this reason the experiment was done to give a recommendation to the farmers for better yield. The present experiment was carried out to examine the effect of boron, zinc and molybdenum on broccoli (cv-green magic) with sole doses of these three micronutrients were fixed 0.3% for borax, 0.5% and 1.0% zinc sulphate as per and 0.03% and 0.05% per ammonium molybdate solutions as sole as well as their combined treatments on the yield and growth parameters of the broccoli. Among the sole treatments, application of zinc showed significantly higher effect on leaves per plants, leaf area, total chlorophyll content of the leaf and ascorbic acid content in the head. Significantly higher plant height showed by the treatments 0.03% Mo+1% Zn (59.10cm) and 0.05% Mo + 1% Zn (59.05cm), respectively. Irrespective of the treatments Zn had significantly positive influence in increasing the number of leaves per plant, especially at 0.5% dose. Significantly highest ascorbic acid was recorded at i.e., 61.54mg/ 100g of fresh head weight along with this significantly highest leaf area were recorded at combination treatment of 0.3%, 0.03% Mo and 0.5% Zn (454.35 cm2) and sole treatment of 0.5% Zn (452.33 cm2). Combination of 0.3% borax, 0.03% ammonium molybdate and 0.5% zinc sulphate were recorded to be best for most of the traits.

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.

Iron-base alloys containing 8-11 wt.% Si, 4-8 wt.% Al, known as “Sendust” alloys, show excellent soft magnetic properties. These magnetic properties are strongly dependent on heat treatment conditions, especially on the quenching temperature following annealing. But little has been known about the microstructure and the Fe-Si-Al ternary phase diagram has not been established. In the present investigation, transmission electron microscopy (TEM) has been used to study the microstructure in a Sendust alloy as a function of temperature.An Fe-9.34 wt.% Si-5.34 wt.% Al (approximately Fe3Si0.6Al0.4) alloy was prepared by vacuum induction melting, and homogenized at 1,200°C for 5 hrs. Specimens were heat-treated in a vertical tube furnace in air, and the temperature was controlled to an accuracy of ±2°C. Thin foils for TEM observation were prepared by jet polishing using a mixture of perchloric acid 15% and acetic acid 85% at 10V and ∼13°C. Electron microscopy was performed using a Philips EM 301 microscope.
