A crop height model (CHM) can be an important element of the decision making process in agriculture, because it relates well with many agronomic parameters, e.g., crop height, plant biomass or crop yield. Today, CHMs can be inexpensively obtained from overlapping imagery captured from unmanned aerial vehicle (UAV) platforms or from proximal sensors attached to ground-based vehicles used for reg...

cultivation of high efficacy crops in resource utilization, especially with higher water and radiation use efficiencies is one of the important strategies to achieve the goals of sustainable agriculture. align with these guidelines and in order to estimate light extinction coefficient and radiation use efficiency of sesame a split plot arrangement of two factors based on randomized complete blo...

Use of phosphate-solubilizing bacteria (PSB) as inoculants has concurrently increased phosphorous uptake in plants and improved yields in several crop species. The ability of PSB to improve growth of aerobic rice (Oryza sativa L.) through enhanced phosphorus (P) uptake from Christmas island rock phosphate (RP) was studied in glasshouse experiments. Two isolated PSB strains; Bacillus spp. PSB9 a...

Crop insurance is a viable solution to reduce the vulnerability of smallholder farmers to risks from pest and disease outbreaks, extreme weather events, and market shocks that threaten their household food and income security. In developing and emerging countries, the implementation of area yield-based insurance, the form of crop insurance preferred by clients and industry, is constrained by th...

A biofilm is an aggregate of microorganisms in which cells adhere to each other on a surface. The biofilm forming capacity of five isolate of streptococcus species were tested by microtitre plate assay. The assay was optimized in LB broth for 48h incubation, fixing of cells by heat and staining using solubilizing solution. The optimized microtitre plate assay can be effectively used for the ass...

In this paper, an approach to assessing ecological suitability of crop growth was developed using GIS, through a case study of maize planting in Jilin Province, in the northeast China, in order to improve the accuracy and objectivity of the evaluation, promote the rationality of crop distribution, and increase the efficiency of the agro-resource utility. Climate and soil conditions in the regio...

Cropping sequence diversification provides a systems approach to reduce yield variations and improve resilience to multiple environmental stresses. Yield advantages of more diverse crop rotations and their synergistic effects with reduced tillage are well documented, but few studies have quantified the impact of these management practices on yields and their stability when soil moisture is limi...

hargraves-samani method is one of the methods for calculating plant evapotranspiration that needs minimum meteorological data. in order to evaluate et-hs model in determining sugar beet crop water demand in isfahan, an experiment was conducted at research field of department of agriculture, khorasgan branch, islamic azad university, isfahan, iranin 2005. the study was based a randomized complet...

A crop can be represented as a biotechnical system in which components are either chosen (cultivar, management) or given (soil, climate) and whose combination generates highly variable stress patterns and yield responses. Here, we used modeling and simulation to predict the crop phenotypic plasticity resulting from the interaction of plant traits (G), climatic variability (E) and management act...

Microbial amendments have received considerable interest in sustainable agriculture for enhancing crop productivity, improving soil quality, and reducing inputs of chemical fertilizers and pesticides (Hussain et al., 1999). Microbial amendments are also known as biofertilizers, biodynamic fertilizers or microbial inoculants, which are comprised of living microorganisms that can function as chem...
