In order to evaluate the effect of foliar application of humic acid on yield and yield components of red bean cultivars this experiment was conducted at Agricultural Research Station of Arak in 2014. The experiment was in split plots Completely Randomized Block Design (CRBD) with three replications. Three level of humic acid i.e. 0, 1.5 and 3 liters per hectare in main plots and three cultivars of red bean i.e. Derakhshan, Goli and D81083 were in sub plots used as treatments. Results of study revealed that line D81083 along with 3.0 liters per hectare of humic acid application shows superiority over the other treatments and showing 13622 kg per hectare final biomass yield. Among various tested cultivars, the lowest biomass yield (10311.1 kg/hectare) was obtained from Derakhshan cultivar without humic acid application. Further, amongst various tested doses of humic acid, highest seed yield (4253.7 kg/hectare) was reported from the cultivar line D81083 at 1.5 liter per hectare of humic acid application while the lowest yield obtained in Derakhshan without humic acid. Results of current study revealed relationship between bean cultivars and humic acid application and interaction of these two affect the yield and yield attributes of red bean.
This experiment was carried out to evaluate the effect of halt irrigation and bio fertilizer on plant yield, seed nutrients content, relative water content (RWC) and chlorophyll index (SPAD) of Goli genotype of red bean (Phaseolus vulgaris L.), based on split plot design with three replications during two years of 2014-2015 at Arak, Iran. Halt irrigation was in main plots by four levels of control (full irrigation), halt irrigation in vegetative stage, at flowering stage and pod filling stage and four bio fertilizer were in sub plots, including: control (no bacteria), Phosphorus Solublizing bacteria (PSB), potassium solublizing bacteria (KSB) and concurrent use both of PSB and KSB. Analysis of variance showed that no significant effect of years but the effect of halt irrigation treatments was significant on plant yield, N, P, K and Zn percentage of seed, relative water content (RWC) and chlorophyll index (SPAD). Halt irrigation reduced plant yield by 67.81% in comparison to full irrigation during flowering stage. In the study, physiological characteristics such as RWC, N, P, K and Zn contents were also reduced significantly with halt irrigation at flowering stage than its effects on other stages of the crop. Also other characteristics was significantly reduced in this study with halt irrigation that this reduction in flowering stage was more than other stages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
