The nitrogen (N) fertilizers are markedly lost as ammonia volatilization from alkaline soils and hence is deemed as major cause of lower N utilization by field crops. The current study explored possible measures to reduce N loss from applied fertilizer and enhance its availability to wheat crop grown on alkaline soil. The treatments involved Zinc-c...
Low wheat production is linked to soil degradation, low organic matter, temperature variation, and nutrient depletion in soils of semiarid regions. Nitrogen is mostly applied as urea to meet crop requirements; however, excessive N application may pollute the environment and contaminate groundwater. The current studies explored possible ways for dec...
The present study aims to enhance the morpho-phsyiological traits, effective utilization of phosphorus and potassium, nutritional quality, and maize productivity using combinations of inorganic and organic amendments in alkaline calcareous soil. The inorganic fertilizers were applied as control (PK 0), recommended PK (PK R), and 75% of PK R (PK R75...

Azolla
is a free-floating hydrophyte fern grown in temperate and tropical regions. The specialized dorsal leaves of the fern possess cavity that harbors cyanobacteria capable of fixing atmospheric nitrogen (N) through biological processes. It is either incorporated into the soil before rice transplanting or grown as an inter-crop with rice crop. It...

Leaves of Calendula officinalis belonging to the family Asteraceae, were evaluated for phytochemical, antioxidant and cytotoxic studies. The leaves of Calendula officinalis were extracted by maceration with different polarity solvents such as n-hexane, chloroform, ethylacetate, n-butanol and 80% methanol. The qualitative analysis of phytochemicals...
