Drought is a major constraint to rice (Oryza sativa) yield and its stability in rainfed and poorly irrigated environments. Identifying genomic regions influencing the response of yield and its components to water deficits will aid in our understanding of the genetics of drought tolerance and development of more drought tolerant cultivars. Quantitative trait loci (QTL) for grain yield and its co...

1. Agriculture is the predominant user (75-80%) of the available freshwater resource in many parts of the world. At present most of the water used to grow crops is derived from rainfed soil moisture, with non-irrigated agriculture accounting for some 60% of production in developing countries. Although irrigation provides only 10% of agricultural water use and covers just around 20% of the cropl...

The semiarid lands of Northeast Brazil represent one the most densely populated regions country. Rainfall variability together with land degradation and large-scale poverty in rural areas makes this region vulnerable to droughts. Most agriculture is rainfed deficient rainfall leads severe drought impacts. In review, we examine different short- long-term strategies directed cope possible impacts...

The sustainability level of current rice farming practices in Thailand was assessed based on in-field data from interviewing 2000 farmers covering six varieties and their different production systems. Data were collected farmers’ characteristics activities according to the 41 requirements Sustainable Rice Platform (SRP) standard. SRP scores ranged 53 81%, with best performance by Khao Dawk Mali...

Corn (Zea mays L.) hybrid selection is one of the most important agricultural management decisions made by farmers. Both genetic yield potential and adaptation to local environment vary widely across corn hybrids, have a direct impact on input costs. This study compared performance hybrids with contrasting comparative relative maturity (CRM, referring their growth cycle), evaluate differences i...

The study aimed to estimate the level of yield gaps maize in major producing areas, point out causes farmers’ fields, and identify opportunities existing through management practices production Central Java. This is strategy for closing achieve food self-sufficiency agricultural land. Methods estimates should cover data sources on physical conditions (weather soil), practices, smallholder shape...

Tailored interventions in the tomato sector require current information on production and marketing systems along with constraints faced by stakeholders. We conducted this study to understand practices, stakeholders’ varietal preferences, market trends, challenges crop’s value chains. A multistage sampling method coupled a random walk was used identify survey locations 180 respondents across se...

With uncertainty in future irrigation water availability and regulations on nutrient application amounts, experimentally determined effects of “controllable” management strategies such as nitrogen (N), water, and their combination on crop water productivity (CWP, also known as crop water use efficiency) and actual evapotranspiration (ETa) are essential. The effects of various N application rate...
