Nanoscience coupled with nanotechnology emerged as possible cost-cutting approach to prodigal farming and environmental clean-up operations. Hence there is a need for more innovative fertilizer that can increase the productivity of agricultural systems friendly than synthetic fertilizers. The trial was laid out in randomized complete block design 11 treatments three replications. field experime...

Phosphorus (P) deficiency in soil limits crop yields and can be managed by P fertilizers. But mere applying fertilizers alone may not effective justifying its bioavailability. At present global reserves are declining an increasing way which urges us to find out alternatives. Thus, the work was taken prepare phosphocompost using water hyacinth (Eichhornia crassipes) as feedstock, termite, normal...

Pigeon pea (Cajanus cajan (L.) Mills.) is one of the major grain legume crops grown in the tropics and sub-tropics and accounts for about 5% of world legume production. It is the fifth prominent pulse crop in the world and second most important pulse crop after chickpea in India. India is ranking first having about 90% of the world area and 85% of production. Organic farming in recent years gai...
