Response of yam varieties to soil moisture regime in Southwestern Nigeria

Priapism in southwestern Nigeria.

OBJECTIVES To determine the aetiology, pattern of presentation, treatment regimen and outcome of management of priapism in our environment and to compare our findings with previous studies in this country and elsewhere. DESIGN A 10-year retrospective study from January 1991 to December 2000. SETTING Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. PATIENTS AND METHO...

Observed timescales of evapotranspiration response to soil moisture

[1] The sensitivity of evapotranspiration (ET) to soil moisture storage plays an important role in the landatmosphere system. Yet little is known about its magnitude, or its dependence on vegetation, soil, and/or climate characteristics. Here we relate the sensitivity to the timescale of ET decay in absence of rainfall, and show that it can thus be derived from time series of ET alone. We analy...

Response of two soybean cultivars to moisture stress

An evaluation of ASCAT surface soil moisture products with in-situ observations in southwestern France

A long term data acquisition effort of profile soil moisture is currently underway at 13 automatic weather stations located in southwestern France. In this study, the soil moisture measured in-situ at 5 cm is used to evaluate the normalised surface soil moisture (SSM) estimates derived from coarse-resolution (25 km) active microwave data of the ASCAT 5 scatterometer instrument (onboard METOP), ...

Response of Two Indica Rice Varieties to Salt Stress

  Salinity is one of the most challenging problems that adversely affects growth and development of plants. Therefore, understanding of the mechanisms that enable plants to adapt to salinity stress will ultimately help in the selection of stress tolerant cultivars for exploiting saline soils. The main objective of this study was to examine the effects of NaCl on some physiological and biochemic...
