Impacts of drought-tolerant maize varieties on productivity, risk, and resource use: evidence from Uganda
Weather variability is an important source of production risk for rainfed agriculture in developing countries. This paper evaluates the impacts of the adoption of drought-tolerant maize varieties on average maize yield, ...
Effect of Ppd-1 photoperiod sensitivity genes on dry matter production and allocation in durum wheat
Understanding the effect of genetic factors controlling flowering time is essential to fine-tune phenological development and to maximize yield. Thirty-four spring durum wheat genotypes classified in five allelic combinations ...
Differential productivity response of rain fed sorghum (Sorghum bicolor L.) genotypes in relation to graded levels of nitrogen in Kellem Wollega zone of Ethiopia, East Africa
(International Journal of Life Sciences, 2015)
Field experiment was conducted at Haro Sabu Agricultural Research Center using three sorghum genotypes (Lalo, Chemada and Local) during the rainy cropping season of 2014 with an objective to determine the effect of nitrogen ...
Genetic gains in wheat in Turkey: winter wheat for dryland conditions
Wheat breeders in Turkey have been developing new varieties since the 1920s, but few studies have evaluated the rates of genetic improvement. This study determined wheat genetic gains by evaluating 22 winter/facultative ...
Improvement in water productivity without yield penalty of direct seeded rice under Micro Irrigation Systems and tillage options in Indo- Gengetic Plain of India
Declining water table in alarming rate is major challenge of sustainability of rice in South Asia. To address this challengea field experiment was conducted from kharif 2012 and 2013 on a loam soil to evaluate the performance ...
Response of bread wheat to rate and timing of nitrogen application in marginal rainfall zone in Ethiopia
(African Crop Science Society, 1994)
Nitrogen fertilizer rate by timing trials were conducted on bread wheat (Triticum aeslivum L) in peasant farmers' fields during two annual cropping seasons for three years in a drought-prone district of southeastern Ethiopia. ...
Synthetic hexaploid wheat: yesterday, today, and tomorrow
(Elsevier; Chinese Academy Of Engineering, 2018)
In recent years, wheat yield per hectare appears to have reached a plateau, leading to concerns for future food security with an increasing world population. Since its invention, synthetic hexaploid wheat (SHW) has been ...
