  • Ultrathin silicon nitride SiNx membrane suspended on a silicon wafer is a popular twodimensional platform in MEMS applications. The unsupported membrane has a low thermal conductivity, is electrically insulated, and very robust against mechanical impact. Remarkably thin, it is difficult to fabricate and manipulate. Recently equipped with a dual chamber system for plasma enhanced chemical vapor deposition (PECVD) and reactive ion etching, we calibrate it to deposit silicon nitride Si3N4, silicon dioxide SiO2, and to dry etch these materials.

  • An on –farm trial was conducted on various farmers field in different villages of Araria district during financial year 2016-17. This trail was conducted to overcome weed infestation during cultivation of chilli in farmers field. It leads to reduction in yield; quality of produce is inferior as compared to better quality produce, increased the cost of cultivation due to manual hand weeding by laborers and reduced the benefit cost ratio. The trial was conducted in randomized block design with three treatments and ten replications.

  • One of the easiest and efficient way of water conservation to solve drinking water scarcity is rooftop water harvesting. To evaluate the performance of the first flush with micromesh filter system, inflow and outflow of the rooftop water samples were analysed for pH, EC, TDS, SAL and TSS parameters. In general, the PH, electrical conductivity, and TDS of the roof water samples were within the drinking water standards and the first flush with micromesh filter system was found to reduce TDS values.

  • An investigation was carried out on sandy loam soils of tarai regions of Uttarakhand to analyze the potential of drip irrigation along with mulch technically as well as economically. The treatments of the study were comprised of four irrigation levels (0.3, 0.4, 0.5 and 0.6 P.E) with mulch (silver/ black-100 micron) and non-mulch conditions along with control (100% P.E). The study revealed that drip irrigation along with mulch showed better performance in terms of yield, water use efficiency as well as economics. Maximum yield of 18.72 t/ha along with maximum net return of Rs 213990.
