When averaged across the three growing seasons of the study, regression analyses indicated that 25R47 had maximum yield at ~1,320,000 seeds/acre, close to the recommended rate of 1,400,000 seeds/acre (Table 1). In contrast, 25R62 had a maximum yield at ~ 1,030,000 seeds/acre, about 400,000 seeds/acre less than the current recommended rate (Table 1). Furthermore, this variety did not respond to ...
Photoactivation of plants by laser treatment is a promising direction in the development modern agricultural production. Treatment with radiation specified characteristics stimulates plants, formation generative traits and an increase yield. An approach based on use specialized installation mounted unmanned aerial vehicle (UAV) proposed to automate process photoactivation large cultivated areas...
the era of transgenic breeding or GMO technologies, the 21st century is silently turning to non-transgenic breeding or non-GMO technologies. Due to significant regulatory issues, cost of development and technology constraints, transgenic breeding technologies have been limited to a few crops grown on large acreages, i.e. about 10% of the available cultivated acres globally1. The promise of non-...
A study of equilibrium acreage allocation decisions at the farm and regional levels under risk aversion, yield uncertainty, and endogenous crop prices is undertaken in a two-crop, two-region setting. The main insight is that a partial specialization in one crop at a regional level may be an equilibrium dominant strategy relative to the more diversified crop mix produced on farm. This is due to ...
The acreage planted in corn and soybean crops is vast, and these crops contribute substantially to the world economy. The agricultural practices employed for farming these crops have major effects on ecosystem health at a worldwide scale. The microbial communities living in agricultural soils significantly contribute to nutrient uptake and cycling and can have both positive and negative impacts...
Agriculture holds a pivotal role in context to India, which is basically agrarian economy. Crop type identification is a key issue for monitoring agriculture and is the basis for crop acreage and yield estimation. However, it is very challenging to identify a specific crop using single date imagery. Hence, it is highly important to go for multi-temporal analysis approach for specific crop ident...
Biotechnology has been practiced by man since plants and animals were first domesticated thousands of years ago. Biotechnology in its most simplistic sense is the genetic modification of living organisms. Hence, all crop varieties grown today, including soybean, have had their DNA manipulatedthe essence of biotechnology. More recently, biotechnology implies a deliberate manipulation of the DNA...
Risk and uncertainty have an important role in determining farmers' goals and their decision making. Risk affects optimal use of inputs and production efficiency. Using production inputs especially new inputs is one of the effective factors in production risk hence, it is necessary to obtain information about inputs use risk in order to find solution to risk management. For investigating effect...
