it is very important to test and evaluate the performance and ability of new-design machinery in comparison with available ones. based on this, a tractor front-mounted rice reaper was compared and evaluated with tiller- mounted and self-propelled reapers. field experiments were conducted to determine forward speed, field capacity, harvesting losses, labor and costs. experiments were conducted b...

To increase crop yield per unit of scarce water requires both better cultivars and better agronomy. The challenge is to manage the crop or improve its genetic makeup to: capture more of the water supply for use in transpiration; exchange transpired water for CO2 more effectively in producing biomass; and convert more of the biomass into grain or other harvestable product. In the field, the uppe...

Reducing water losses in agriculture needs a solid understanding of when evaporation (E) occur and how much is used through crop transpiration (T). Partitioning ecosystem T however challenging, even more so it comes to short-statured crops, where many standard methods lead inaccurate measurements. In this study, we combined biometeorological measurements with Soil-Plant-Atmosphere Crop (SPA-Cro...

Interactions between plants and insect herbivores are important determinants of plant productivity in managed and natural vegetation. In response to attack, plants have evolved a range of defenses to reduce the threat of injury and loss of productivity. Crop losses from damage caused by arthropod pests can exceed 15% annually. Crop domestication and selection for improved yield and quality can ...

Investment in the agricultural sector is important because this sector greatly affects the realms of providing food independence and security, employment, sustainable development, and environmental preservation. So, this study investigated the socio-economic impacts (direct and indirect effects) of the investment development policy on the agricultural sector and its sub-sectors in Iran in 2011 ...

Carleton (1) established that high temperature has caused 59,300 suicides during 1987–2013 in India and for temperatures above 20 °C, a 1 °C increase in a single day’s temperature causes ∼70 suicides in the country. The author argues that high temperature stimulates suicides through a crop-damaging agricultural channel as the temperature deviations above the 20 °C threshold in growing season ar...
