experiment was conducted in 2011 to evaluate the efficacy of reduced herbicide rates in combination with false seedbed for selective weed control in common bean. the experiment was carried out with a completely randomized factorial design. factors were herbicide dose (post-emergence application of imazethapyr at the rates of 0, 25, 50, 75, and 100 g a.i. ha-1) and seedbed preparation (false see...
In order to evaluate the growth indices of sugarcane in different irrigation systems, weed control treatments and correlative associations with quantitative and qualitative traits of sugarcane, an experiment was conducted as split plot based on randomized complete block design (RCBD) with three replications in 2020 at Sugarcane Development Research and Training Institute of Khuzestan, Ahwaz, Ir...
sowing date is the most important factor in physiological and morphological characteristics with positive effects on plants. to evaluate the effect of sowing date and weed interference on yield and yield components of red beans cultivars a factorial split plot experiment in randomized complete block design with three replications was carried out in the research field of zanjan university. main ...
Smallholder farmers in southern Africa have reported on increased labour requirements for hoe weeding due to high weed infestations in conservation farming (CF) fields. However, CF proponents claim that weed pressure and labour requirements for weeding decrease within the first three years under the recommended CF practices. An observational study was carried out during the 2008/09 cropping sea...
abstract field experiment was conducted to evaluate the effects of sowing date, crop density, and weed interference on yield and yield components of chickpea in lorestan province during 2005-06. the experimental was a randomized complete block design by factorial arrangement with 4 replications. the experiment had 3 factors: sowing date at 2 levels (autumn, and winter), crop density at 3 levels...
