Estimating the spatial variability of various plant parameters during the growing season can assist in timely correction of stress conditions within a field. This research illustrates that the nitrogen reflectance index (NRI) developed to estimate plant nitrogen status can be used to estimate plant parameters and yield potential. The study was conducted on two experimental maize sites. Selected...

The study attempted to analyse the effects of age, pruning, and fertilizer application on tea yield and to derive a relation between yield and tea leaf area index (LAI). The study was motivated by the fact that tea yield has stagnated in Northeast India. To study the effects of age, pruning, and fertilizer application on tea yield, statistical analysis was applied to the data set collected at t...

Leaf shape, including leaf size, leaf dissection index (LDI), and venation distribution, strongly impacts leaf physiology and the forces of momentum exerted on leaves or the canopy under windy conditions. Yet, little has been known about how leaf shape affects the morphological response of trees to wind load. We studied eight Quercus species, with different leaf shapes, to determine the morphol...

this experiment was conducted to study the effect of plastic mulch on the growth and some physiological characteristics of two strawberry cultivars (paros and queen elisa) under drought stress. a factorial experiment was performed based on randomized complete block design with four treatments, including mulch, without mulch, normal irrigation (control) and deficit irrigation (-10 bar) with thre...

Effects of doses of gibberellic acid (GA3) were studied on the growth and performance of strawberry cultivar ‘Chandler’. GA3 was applied as foliar spray at three leaf stages @ 50, 75, 100 and 150 ppm. The applied GA3 @ 150 ppm significantly increased the plant height, leaf area index (LAI), crown size and fruit yield. However, this dose of GA3 (150 ppm) significantly decreased the shelf life an...

the seedbed preparation and cereal residue present due to limit of maize (zea mays l.) growing period are a major challenge in double cropping after winter cereals in iran as: shahrekord. in this research, effects of various seedbed preparation methods and crop residuea managements on vegetative growth and yield of forage maize (ksc 704) were studied in a barley-maize double cropping during 200...
