A field experiment was conducted with four wheat varieties Raj4134, HD2733, NW 1014 and K9006 for characterization of heat stress tolerance traits under heat stress condition. Heat stress was induced by delayed sowing of 35 days from normal date of sowing so that grain filling stage of wheat could experience severe heat stress. Data related to plant height, chlorophyll content, starch content a...

Knowledge of the nitrogen nutrition status vine is essential for long-term management its with aim producing high-quality grapes. Measurement chlorophyll index a fast, non-destructive and relatively inexpensive method that provides good approximation during growing season. Several meters are available on market, each using own measurement unit. With popularizing use meters, interpretation thres...

Rice leaves display lateral asymmetry around the midrib, and the narrow side exhibits higher leaf area-based nitrogen concentration (Na) and soil plant analysis development (SPAD) values than the wider side. However, the difference in the relationship between the SPAD of each side and Na of the corresponding lateral half, and the optimal position along the leaf blade for SPAD measurements are n...
