Effects of Drought on Crop Yield Potential

Abstract

Article Info Drought is a recurrent feature of the climate, varying in intensity, duration, and frequency across the climatic spectrum. A drought can have substantial economic, environmental, and social impacts. Drought is a weather-related natural disaster. It affects vast regions for months or years. It has an impact on food production and it reduces life expectancy and the economic performance of large regions or entire countries. Conventional plant breeding attempts have changed over to use physiological selection criteria since they are time consuming and rely on present genetic variability. Tolerance to abiotic stresses is very complex, due to the intricate of interactions between stress factors and various molecular, biochemical and physiological phenomena affecting plant growth and development. High yield potential under drought stress is the target of crop breeding. In many cases, high yield potential can contribute to yield in moderate stress environment.

An Insider Within

“…Examples here are managing aspects of the researchers' insider or outsider status by highlighting those identities which facilitate rapport and data collection 60 as well as levelling power imbalances through cultivating a more reciprocal relationship with research participants by "locally institutionalizing" the knowledge acquired from the research. 61 Additionally, tackling the emerging limitations of insider status facilitated the implementation of grounded theory strategies that require the researcher to reserve their interpretations and allow the data to speak for itself.…”
