the objective of this study was to determine the allowed and desired limits for heavy soils of texture (clay loom), as it has operational capability (friability), these limits were 6.34 mm for planting and 10.62 mm for harvesting in each raining or irrigation episode. we determined some factors that affect soil wetness and water content as follow: the amount and severity of rain, the condition ...

In order to investigate the effect of planting date and sowing method on ear yield, water use efficiency and some physiological characteristics of sweet corn, an experiment was carried out as a split plot based on a randomized complete block design with three replications in Yasouj, south-west of Iran. Planting date consisted of five levels (4 May, 19 May, 4 June, 19 June, 5 July) and considere...

Soaking potato tuber pieces for 15 min in 8,000 mug/ml of oxamyl just before planting reduced the number of Globodera rostochiensis cysts that developed on potato roots, but this treatment was phytotoxic. Five foliar applications of 1.12 kg a.i./ha of oxamyl or carbofuran at 10-day intervals beginning when 90% of the plants had emerged suppressed increase in G. rostochiensis densities. Similar ...

For estimation of grain yield in wheat, Normalized Difference Vegetation Index (NDVI) is considered as a potential screening tool. Field experiments were conducted to scrutinize the response of NDVI to yield behavior of different wheat cultivars and nitrogen fertilization at agronomic research area, University of Agriculture Faisalabad (UAF) during the two years 2008-09 and 2009-10. For recordi...
