FAO’s water-driven crop growth simulation model, AquaCrop, was calibrated and validated for cassava (Manihot esculenta Crantz). Existing datasets, used in similar published works, were shared covering several years regions (Colombia, Nigeria Togo). Different varieties tested the case of Colombia a single variety (TME-419) Togo. Overall biomass simulations resulted an R2 0.96 RMSE 1.99 tonne DM/...

The effect of mycorrhiza fungi was studied on growth and yield of potato (Solanum tuberosum L.) in Fereidoonshahr, Esfahan, Iran during 2013 growing season. The experiment treatments were arranged in a factorial design based on a complete randomized block design with three replications. Four phosphorus fertilizer levels of 25%, 50% 75% and 100% P recommended with two levels of Mycorrhiza: with ...

Emissions of nitrogen oxides (NOx) from aircraft cause air quality degradation and climate change. Use ultra-low sulfur fuel along with post-combustion emissions control results in a net benefit 304 USD per metric tonne jet burned.

in order to find the superior genotypes and high yielding potato varieties, the experiment was carried out on 33 introduced potato genotypes and varieties based on a complete randomized block design with four replications, in which a number of morphological characteristics were investigated. results of analysis of variance on the recorded traits revealed that the studied genotypes were signific...

In this paper we develop methods to investigate the efficiency of alternative contracts for Carbon (C) sequestration in cropland soils, taking into account the spatial heterogeneity of agricultural production systems and the costs of implementing more efficient contracts. We describe contracts being proposed for implementation in the United States and other countries that would pay farmers for ...

this study examined the environmental impacts of irrigated and rainfed barley agroecosystems of iran based on nitrogen levels by using lca methodology during 1999-2013. four steps includung goal definition and scoping, inventory analysis, life cycle impact assessment and integration & interpretation were considered. impact categories were acidification, eutrophication and global warming. functi...

this study aimed at evaluating some quantitative and qualitative properties of potato as one of the main commercial products in iran. to this end, a split plot experiment on the basis of randomized complete bloke design with silicone and iron was carried out in jiroft as one of the commercial area of planting potatoes. the main factor included different levels of silicon (0, 10, 20, 30 mm.l-1) ...

This study was performed in order to determine the distance of isolation for the seed potato production from ware potato in three regions of Ardabil, Namin and Nir. The experiment was carried out in a randomized complete block design (RCBD) with five distances (100, 200, 300, 400 and 500 meters from ware potato) and three replications with Super Elite (SE) class of Agria potato cultivar from wa...

The economic, social and environmental costs of food waste are being increasingly recognised. Food waste consists of both edible and inedible components. Whilst wastage of edible food is problematic for obvious reasons, there are also costs associated with the disposal of the inedible fraction to landfill. This is the third in a series of papers examining the costs of food waste throughout the ...
