Timing and Rate of Phosphorus Application Influence Maize Phenology, Yield and Profitability in Northwest Pakistan
Phosphorus (P) is the second most important crop nutrient after nitrogen that increases productivity and profitability of maize (Zea mays L.) on P deficient soils in Northwest Pakistan. The objective of this study was to find the best level and time of P application for higher maize (cv. Azam) productivity and profitability. Field experiment was conducted at the Research Farm of Khyber Pakhtunk...

متن کاملPotential for Successional Theory to Guide Restoration of Invasive-plant-dominated Rangeland
Ecologists are searching for models, frameworks, and principles that provide a bridge between theory and the practice of restoration. Successional management has been proposed as a useful model for managing and restoring invasive-plant-dominated rangeland because it provides a framework in which ecological processes can be manipulated by managers to achieve a desired plant community. Succession...
متن کاملOn the Optimal Frequency and Timing of Control Points in a Project’s Life Cycle
The dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. Collection of information about the performance of projects at control points costs money. The corrective actions that may need to be taken to bring the project in line with the plan also costs money. On the other hand, penalties are usually...
متن کاملTiming of seasonal migration in mule deer: effects of climate, plant phenology, and life-history characteristics
Phenological events of plants and animals are sensitive to climatic processes. Migration is a life-history event exhibited by most large herbivores living in seasonal environments, and is thought to occur in response to dynamics of forage and weather. Decisions regarding when to migrate, however, may be affected by differences in life-history characteristics of individuals. Long-term and intens...
