Crop density is a key agronomical trait used to manage wheat crops and estimate yield. Visual counting of plants in the field is currently the most common method used. However, it is tedious and time consuming. The main objective of this work is to develop a machine vision based method to automate the density survey of wheat at early stages. RGB images taken with a high resolution RGB camera ar...

In an effort to determine the biochemical markers for identifying genotypes before sowing for drought tolerance, changes in activities of antioxidant enzymes were determined in the seedlings of five drought-tolerant and five drought-sensitive wheat (Triticum aestivum L.) genotypes, each with different genetic background growing under normal and water deficit conditions induced by 6% mannitol. I...

In the area with terminal heat and drought stress such as Gonbad, allocation of produced dry matter to reproductive organs is of great importance. In order to evaluate the effect of different temperature and moisture regimes on dry matter distribution and harvest index ofcanola an experiment wasconducted at Agricultural Research Station of Gonbad during 2005-2007. The experiment was a RCBD arra...

Wheat (729.8 million tons) is second to rice as the main human food crop (FAO, 201415). In India, wheat is cultivated extensively in North-Western and Central zones. The area, production and productivity of wheat in India and Haryana during 2014-15 is 31.46 mha, 86.53 mt, 2749 kg ha -1 and 2.60 mha, 10.35 mt, 3980 kg ha -1 , respectively (Anonymous, 2014-15). Late sowing of wheat is a major pro...

In order to evaluate the effects of plastic bed mulch and sowing date on early maturity, growth and yield of Ahvazi-Okra and obtaining the highest production during the peak price period, an experiment was executed in Agricultural and Natural Resources Research Center of Khuzestan. The experiment was laid out as split plot design in RCBD with four replications. Four sowing dates including Feb. ...

Transplanting or pot culture has been mentioned as a promising approach to increase crop yield and decrease irrigation water use in recent years. Using simulation models to assess pot culture is a valuable way in investigating the effect on yield, water consumption and other properties of crops such as soybean. For this purpose, several pot culture levels (seedling sizes) plus direct sowing wer...

Irrigation is crucial to agriculture in arid and semi-arid areas and significantly contributes to crop development, food diversity and the sustainability of agro-ecosystems. For a specific crop, the separation of its irrigated and rainfed areas is difficult, because their phenology is similar and therefore less distinguishable, especially when there are phenology shifts due to various factors, ...
