Consistent use of high RSC water may deteriorate the physical properties of soil and increases pH and SAR of soil. Continuous use may reduce germination / the establishment of seedling, retards plant growth and leads to a significant reduction in yield. Therefore, a field experiment in microplots was displayed at research plot in St. John’s College, Agra to study the effect of sodic water on th...

investigating the decomposition of crop residues using woodborn and soilborn saprophytic fungi this experiment was conduceted to evaluate the effect of some fungi on decomposition of crop residues. crop residues from rice, wheat, cotton, canola and soybean were inoculated with pleurotus ostreatus, phanerochaete chrysoporium, aspergillus niger and trichoderma viride in vitro. after 30 days, hemi...

Energy crops can provide a sustainable source of power and fuels, and mitigate the negative effects of CO2 emissions associated with fossil fuel use. Miscanthus is a perennial C4 energy crop capable of producing large biomass yields whilst requiring low levels of input. Miscanthus is largely unimproved and therefore there could be significant opportunities to increase yield. Further increases i...

Is the crop economically feasible (profitable)? The most comprehensive way to determine if an alternative crop is economically feasible is to complete an enterprise budget. The enterprise budget is a projection of the manager’s estimates, and is a tool to estimate net profit by estimating revenues and subtracting operating and ownership costs associated with a particular crop. To create an ente...

Reuse of saline subsurface drainage water for irrigation has been identi®ed as a potential option for managing drainage volumes and sustaining crop productivity in California's San Joaquin Valley. Soil surface structural instability, crusting and poor stand establishment may, however, be constraints in drainage reuse systems. The objective of this ®eld study was to evaluate the effectiveness of...

This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. The authors suggest agronomic practices, including tillage practices, rotations, and input management options that can ameliorate important constraints and sustainably improv...
