Benzoxazolin-2(3H)-one (BOA) is a well known allelochemical that is being explored for its herbicidal activity. However, not much is known about its effect on crop plants. The present study investigated the effect of BOA on germination and early growth of four vegetable crops viz. Pisum sativum L., Raphanus sativus L., Brassica oleracea L. var. botrytis and Brassica oleracea L. var. capitata. A...
متن کاملSpatial variability of some soil properties for site specific farming in northern Iran
Evaluating agricultural land management practices requires knowledge of soil spatial variability and understanding their relationships. Spatial distributions for fourteen soil physical and chemical properties were examined in a wheat field in Sorkhankalateh district, in Golestan province, Iran. 101 soil samples at the distances of 5m, 10m and 20m as nested grid were collected at the depth of 0-...
متن کاملEffect of Incorporation of Crops Residue into Soil on Some Chemical Properties of Soil and Bioavailability of Copper in Soil
Objective: Returning crop residue to the soil exerts favorable effects on physical and chemical properties of soil. In fact, the plant residues can affect soil conditions such as pH and important role in soil fertility and cycling of elements in the soil may have. In addition to the role of the organic matter from decomposition of crop residue in increasing the concentration of micronutrients i...
