This research was carried out in 2014 and 2015 to assess the effects of salicylic acid (SA)(0 and 1 mM) and abscisic acid (ABA) (0 and 50 µM) on essential oil content and yield ofajowan (Carum copticum L.) organs under different irrigation intervals (I1, I2, I3, I4: irrigationafter 70, 100, 130 and 160 mm evaporation, respectively). Plants were sprayed by SA and ABAat vegetative and reproductiv...

The relationship between arbuscular mycorrhizal fungi (AMF) and their associated bacteriacan be has great importance for sustainable agriculture especially in the case of highlymycorrhizal plants such as linseed. To evaluate the possible effect of AMF in association withphosphate solubilizing bacteria (PSB) on linseed plants, a 2-yr factorial experiment wasconducted based on a randomized comple...

In order to study the effects of weeding and plant density on forage yield of two sorghum cultivars, an experiment was conducted in 2011 at Bahonar University of Kerman Research field station. The experiment was designed as a randomized complete block with a factorial-split treatment arrangement and with three replications. Treatments were included four levels of weeding (whole season wedding, ...

Chemical fertilizers have important role in modern agriculture, and in the other hand led to rigid environmental pollution. Urea fertilizer is one of the most widely used and least expensive nitrogen fertilizers in Iran. Since it is high solubility in water a significant of it, if irrigation or precipitation is heavy, easily washed and led to change to change the quality of groundwater, rivers ...

We propose techniques for accurate and computationally viable estimation of timing yield using circuit-level Monte Carlo simulation. Our techniques are based on well-known variance reduction approaches from Monte Carlo simulation literature. By adapting these techniques to the yield estimation problem, one can reduce the number of Monte Carlo samples required in order to estimate yield within a...

This study was conducted Ismailoglu grape type (Vitis vinifera L.) and its vine which was aged 15 was grown on its own root in a vegetation period of 2013 in Nevşehir province in Turkey. In this research, it was investigated whether the applications of Control (C), 1/3 cluster tip reduction (1/3 CTR), shoot tip reduction (STR), 1/3 CTR + STR, TKI-HUMAS (TKI-HM) (Soil) (S), TKIHM (Foliar) (F), T...

We employ transient absorption spectroscopy to record the absorption spectrum of photogenerated charge carriers in Cu2O. We have found that CO2 reduction in Cu2O is limited by fast electron-hole recombination. The deposition of RuOx nanoparticles on Cu2O results in a twofold increased yield of long-lived electrons, indicating partially reduced electron-hole recombination losses. This observatio...

A field experiment was conducted during 2001-2003 to evaluate the effect of water stress on the yield and yield components of four rice cultivars commonly grown in Mazandaran province, Iran. In northern Iran irrigated lowland rice usually experiences water deficit during the growing season include of land preparation time, planting, tillering stage, flowering and grain filing period. Recently d...

Dairy buffalo is the major source of milk production kept under peri-urban, low input production system. There is no practice of feeding animals according to requirements; exposing them to nutritional deficiency with the onset of pregnancy. It leads to a decline in milk yield, which compels the farmers to keep the animals un-bred. The present work was conducted to document, the post-conception ...
