Boron deficiency in pastures and field crops
نویسنده
چکیده
Boron deficiency was first recorded in Australia in the 1930s in apple trees growing in Tasmania and New South Wales. Subsequently the deficiency was found in a wide range of pasture and crop plants. Crops with higher boron requirements such as lucerne, sunflowers, rapeseed, cauliflower and apples are most likely to respond to boron. Pine trees, which are commonly used in tree lots and as windbreaks, also have a high requirement for boron.

Soil Boron Extractions as Indicators of Boron Content of Field-grown Crops
BORON (B) is a micronutrient element that plants require in trace amounts.The concentration range in which plants exhibit neither deficiency nor toxicity symptoms is narrower for B than for any other nutrient element. Plants can experience both B deficiency and B toxicity in a single growing season (Reisenauer et al., 1973). In humid regions, rainfall can cause excessive leaching of B, and fert...
متن کاملZinc, boron and sulphur deficiencies are holding back the potential of rainfed crops in semi-arid India: Experiences from participatory watershed management
Little attention has been paid to the diagnosis of deficiencies of micronutrients such as zinc (Zn) and boron (B) and secondary nutrient such as sulphur (S) in rainfed systems. We evaluated Zn, B and S status of 1617 farmers’ fields in 14 districts of the semi-arid tropical India. Results showed that most of the soil samples were low to medium in organic carbon contents. Results also revealed t...

THERE is a restricted range of boron concentration in soil water that is beneficial to plants. At lower concentrations, plants exhibit boron deficiency, whereas at higher concentration, phytotoxicity occurs. The specific range of favorable response varies by species but has been characterized as 0.028 to 0.093 mmol L 1 for sensitive crops and 0.37 to 1.39 mmol L 1 for tolerant crops (Keren and ...
متن کاملRole of Boron in Vascular Plants and Response Mechanisms to Boron Stresses
To date, the primordial function of boron is its structural role in the cell wall through stabilization of molecules containing cis-diol groups (borate esters with apiose residues of rhamnogalacturonan II). Nonetheless, boron is a micronutrient also involved in a great variety of physiological processes in vascular plants. However the mechanisms underlying the various metabolic disorders caused...
متن کاملThe Role of Micronutrients in Crop Production and Human Health
The soils in Pakistan across 22 Mha cultivated area are predominantly alluvial and loessal, alkaline in pH, calcareous and low in organic matter. These factors are mainly responsible for nutrient fixation in soil and low availability to plants. Zinc (Zn) deficiency in Pakistan was the first micronutrient disorder recognised in early 1970s as a cause of hadda disease in rice. After identificatio...
