Nitrogen (N) availability and soil microbiota exert significant impacts on plant metabolic systems yield. Different studies have indicated that yield nitrogen use efficiency (NUE) of pearl millet (Pennisetum glaucum L.R.Br.) can be improved by the inoculation N-fixing bacteria. However, interactive effects different N sources bacteria growth, productivity, NUE been less explored. Therefore, ind...

Aonla or Indian gooseberry (Emblica officinalis Gaertn) has become the important fruit crop of arid and semi–arid region of the country because of its hardy nature that makes it suitable to grow in varied edephoclimatic conditions of such regions. The major constraints are moisture stress and inherently poor soil fertility. The uses of mulches help to reduce water consumed (Keramat et al., 2011...

Use of chemical fertilizers have lead to decline in fertility and productivity besides causing deficiency and imbalance of macro and micronutrients. The use of chemical fertilizer and pesticide has posed a serious threat to the environment and resulted in the repercussions on the ecosystem. The chemical residues in the food products are causing injury to human beings and cattle population. Use ...

The effects of nitrogenous (inorganic) fertilisers, organic manures and blue-green algae (BGA) biofertiliser on mosquito populations (Diptera: Culicidae) were studied in rice fields of Madurai, Tamil Nadu, south India, with particular attention to Culex vishnui Theobald, Cx. pseudovishnui Colless and Cx. tritaeniorhynchus Giles, the vectors of Japanese encephalitis (JE). The application of urea...
