There is a growing need to increase global crop yields, whilst minimising use of resources such as land, fertilisers and water. Agricultural researchers use ground-based observations to identify, select and develop crops with favourable genotypes and phenotypes; however, the ability to collect rapid, high quality and high volume phenotypic data in open fields is restricting this. This study dev...

In a pot culture experiment, the root length density, potassium concentration in crop, and total K uptake by wheat (Triticum aestivum var. HD 2285) at different growth stages (CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage) were determined. Wheat crop was grown in 72 pots containing 4.5 kg of three types of soils, namely Alfisol,...

The aim of this study was to predict crop growth of year-round cut chrysanthemum (Chrysanthemum morifolium Ramat.) based on an empirical model of potential crop growth rate as a function of daily incident photosynthetically active radiation (PAR, MJ m-2 d-1), using generalized estimated parameters of the expolinear growth equation. For development of the model, chrysanthemum crops were grown in...

To evaluate the effects of biofertilizers on some physiological growth indices of a soybean cultivar (M9) under water stress condition, a study was carried out in a split plot randomized complete block design in three replications at research station of Bu Ali Sina University, Hamedan, Iran in 2012. The main plots consisted of three levels of irrigation after 50, 100 and 150 mm evaporation from...

 The factors that determine the success of the crop is water content in the soil profile explored by the roots, where soil and management condition affect the storage and availability. Because of the sites defined by the altimetry and crops predecessors affect the behavior of water content stored in the soil available for plants.  The aim of this work was to analyze the relationship between d...

In order to study of quantitative and qualitative yield, chlorophyll content and some growth indices of wheart (Triticum aestivum L.) in response to seed inoculation with plant growth promoting rhizobacteria (PGPR) at different levels of soil salinity, a factorial experiment based on randomized complete block design with three replications was conducted at Research Greenhouse of Faculty of Agri...

Accurate and timely information on rice crop growth and yield helps governments and other stakeholders adapting their economic policies, enables relief organizations to better anticipate and coordinate relief efforts in the wake of a natural catastrophe, and provides technical backbone of an insurance solution where risks of yield losses from the rice smallholders are transferred to the insuran...

Growth indices are useful for interpreting plant reaction to environmental factor. Using Growing Degree Days (GDD) for estimating the phonological growth stages is more valid instead of calendar time. In order to study effect of salinity on growth analysis in three different plantago species, a greenhouse experiment was conducted in Vali-e-Asr University of Rafsanjan in 2009. The study was carr...

introduction lentil with about 28 percent protein occupies the second after soybean. it is one of the major crops in developing countries as a complement to cereals and is an excellent source of protein and amino acids in the diet. results of studies shown that for most crops, including lentil, the occurrence of drought stress in some phenology stages cause irreparable damages to yield. therefo...
