Artificially fabricated hydroxyapatite (HAP) shows excellent biocompatibility with various kinds of cells and tissues which makes it an ideal candidate for a bone substitute material. In this study, hydroxyapatite nanoparticles have been prepared by using the wet chemical precipitation method using calcium nitrate tetra-hydrate [Ca(NO3)2.4H2O] and di-ammonium hydrogen phosphate [(NH4)2HPO4] as precursors. The composite scaffolds have been prepared by a freeze-drying method with hydroxyapatite, chitosan, and gelatin which form a 3D network of interconnected pores.

Pulses are an important source of high quality protein complementing cereal proteins for pre-dominantly substantial vegetarian population of the country. Pigeonpea (Cajanus cajan (L.) Mill sp.) is the second most important pulse crop of India after chickpea and is grown for it’s grain as dhal and green seed as a vegetable. A field experiment was conducted at College of Agriculture, Vishweshwaraiah Canal Farm, Mandya during kharif 2017 to study the effect of foliar application of calcium nitrate, boron and humic acid on growth and yield of transplanted pigeonpea.

The effect of pre harvest spraying of calcium chloride (CaCl2) and calcium nitrate (Ca NO3) @ 0.5 and 1% on shelf life and quality attributes of mango cvs Dashehari and Amrapali was investigated. Pre harvest spray was carried out on fully grown mango trees prior to one month of harvesting following second subsequent spray, 15 days after of first one. Full ripe fruits of both the cultivars were packed in brown papers bags after washing and surface air drying and stored under ambient condition (36 ± 20C at 75 ± 3% RH).

Among the carbon sources, glucose supported highest weight of dried mycelium and maximum number of sclerotia formation followed by sucrose and maltose. The lactose supported least growth and also inhibitory for sclerotia formation. Out of four nitrogen sources, calcium nitrate supported highest weight of dried mycelium and maximum number of sclerotia followed by alanine. Urea exhibited inhibitory effect for sclerotia formation. In the vitamins, Thiamine supported highest weight of dried mycelium and maximum number of sclerotia followed by yeast extract.

A field trial was conducted at Regional Research station, NHRDF, Nashik in three consecutive years during Rabi 2014-15, 2015-16 and 2016-17 on onion variety Agrifound Light Red for the management of onion thrips by applying different doses of nitrogen as basal application. The result showed that, lowest mean thrips population (22.56 nymphs/plant) were recorded in without N (0 % Nitrogen), however, highest gross yield (306.89q/ha) was recorded in higher application of N (100% of the recommended dose as basal application through calcium nitrate).
