ABSTRACT The study aims to quantify the production costs of maize and sorghum crops under rainfed irrigated conditions for generation ethanol evaluate economic feasibility in different scenarios marketing price. Two experiments were carried out years 2019/2020 2020/2021, an experimental area at Federal University Santa Maria, RS, Brazil. experiment was strip plots, a randomized block design fou...

land evaluation is the process of predicting the land use potential on the basis of its attributes. at the present study the qualitative land suitability evaluation was investigated for specific cereal crops including irrigated wheat (triticum aestivum l.), mays (zea mays l.) and cotton (gossypium herbaceum l.), based on fao land evaluation frame works (1976, 1983 and1985), climatic and soil re...

This study is the first of its kind to quantify possible effects of climate change on rice production in Africa. We simulated impacts on rice in irrigated systems (dry season and wet season) and rainfed systems (upland and lowland). We simulated the use of rice varieties with a higher temperature sum as adaptation option. We simulated rice yields for 4 RCP climate change scenarios and identifie...

introduction climate change generally affect all economic sectors, but the agricultural sector is the most sensitive and vulnerable sector, because crops are highly dependent on climatic resource. according to the scientific evidences, climate change in the future, especially the combined effects of rising temperatures and rising co2 concentrations in the atmosphere and increase the likelihood ...

The purposeof this studywas to Analyzing factors that effecting on rangeland degradation. Statistical population of this research consisted of whole farmer in Pirtaj district (N= 1600); from that 120 farmer were selected as sample using cluster sampling. The main tool to collect data was a researcher made questionnaire that Content validity of the questionnaire was approved, by a panel of exper...

The rice land is linked to the climate change due to its methane emission potential. The systems of growing rice and associated soil and crop management practices that have evolved are varied and complex. However, from the methane emission point of view, water regime is a crucial parameter. According to IPCC guidelines the rice ecosystem need to be categorized into four strata for methane emiss...

A genome-wide association study explored the genetic basis of variation for drought tolerance and related traits in a Middle American diversity panel comprising 96 common bean ( L.) genotypes. The panel was grown under irrigated and rainfed conditions and single nucleotide polymorphism (SNP) data were used to explore the genetic diversity and ancestry of the panel. Varying levels of admixtures ...

for comparison the growth characteristics and quantitative and qualitative yield of two summer savory species (such as satureja khuzestanica and s. rechingeri) in response to rainfed and irrigated conditions, an experiment was carried out on the basis of split-plot design in completely randomized block design with three replicates in north of khuzestan during growing season of 2012-2013. irriga...

Rodents cause serious losses to crops in many different parts of the world. The house mouse (Mus domesticus, Schwarz and Schwarz 1943) is a serious pest to agriculture in Australia. The impacts of house mouse damage to crops in Australia were examined. Plagues of mice (>1,000 mice/ha) cause enormous economic and social stress to rural communities in Australia. The mouse plague in 1993/94 caused...
