Global food demand is increasing rapidly, as are the environmental impacts of agricultural expansion. Here, we project global
demand for crop production in 2050 and evaluate the environmental impacts of alternative ways that this demand might be
met. We find that per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a
similarly increasing function of per capita real income since 1960. This relationship forecasts a 100–110% increase in global crop demand from 2005 to 2050.

Zinc (Zn) is the most important micronutrient required for sustainable crop production, particularly for rice and wheat crops. Therefore, on-farm trails (OFTs) were conducted at seventeen different locations during 2006-08 to evaluate the direct and residual application effect of Zn, applied through zinc sulphate heptahydrate under rice-wheat (RW) cropping sequence.

Investigations and experience on truth of natural plant life surrounding us revealed that 1) soil is living, 2) health of cattle influences biodiversity as well as recycling of biomass and 3) quality of water. It is "soul" content of alternate farming.

Stagnating yields, negative impact on environment, soil health and farmers' economy were some of the side effects of green revolution and provided fuel to search new and unexploited areas to ensure increased productivity through eco-friendly or evergreen farming.

For centuries, traditional agricultural systems have contributed to food and livelihood security throughout the world. Recognizing the
