N. Heydari; F. Taran Iranica Journal of Energy and Environment 2024. doi:10.5829/ijee.2025.16.02.08

Other claims from this paper (11)

Intervention effect Climate change has adversely affected wheat yield, especially rain fed wheat in Iran and elsewhere.
Observation Some studies report wheat yield changes greater than the 10-14% estimate.
Mechanism Temperature increase and heat stress are identified as the most important factor in wheat climate impacts.
Intervention effect Climate change can reduce the wheat crop growth period.
Intervention effect Climate change can reduce the planting-to-flowering period.
Intervention effect Climate change can shorten the seed filling period.
Intervention effect Climate change can reduce the flowering-to-maturity and seed production period.
Recommendation Adaptation measures include heat-tolerant, low-water-requirement cultivars, longer-growing cultivars and planting date changes.
Recommendation Adaptation measures include improved on-farm water management, residue management and increased soil organic matter.
Recommendation Wheat adaptation strategies should focus on reducing temperature and heat stress effects, especially at critical growth stages.
Recommendation Climate effects on strategic crops should be mainstreamed and prioritized in national and sub-national research, especially in Iran, to ensure food security.

Other claims from this paper (10)

Intervention effect Foliar fertilizer treatments significantly increased yields at some of six responsive sites.
Intervention effect Foliar fertilizer treatments significantly decreased yields at some of six responsive sites.
Intervention effect The 3–8–15 fertilizer caused no leaf damage.
Intervention effect Other fertilizers caused little or no leaf damage.
Association Leaf damage was not clearly related to yield decreases.
Intervention effect Foliar fertilization seldom increased tissue N–P–K composition, nutrient uptake, or photosynthesis at R2.
Intervention effect Foliar fertilization seldom increased plant weight at R2.
Association A combination of nutrient availability, vegetative growth, and rainfall explained 27% of variation in yield response.
Association Positive yield responses tended to occur when soil or weather reduced plant growth and nutrient availability.

Biomass Production and Hydrological/Water Quality Impacts of Perennial Crop Production on Marginal Land

Qingyu Feng Purdue e-Pubs (Purdue University System) 2013

Other claims from this paper (13)

Observation The watershed contains 641 km2 of marginal land, 23% of its area.
Observation Converting all marginal land to switchgrass could produce 45 million gallons of bioethanol.
Observation Converting all marginal land to Miscanthus could produce 57 million gallons of bioethanol.
Observation Switchgrass production would not support the assumed 50 million gallon biorefinery.
Observation Miscanthus production could support the assumed 50 million gallon biorefinery.
Intervention effect Conversion to the two crops significantly affected hydrology and water quality at marginal land scale.
Observation At watershed scale, the hydrologic and water quality impact could be insignificant.
Association Switchgrass has greater total ET loss than Miscanthus because of non-growing-season evaporation.
Intervention effect Soil erosion would fall under switchgrass and Miscanthus conversion.
Intervention effect Mineral and organic nitrogen and phosphorus would fall with reduced fertilization for biomass production.
Intervention effect Early-season nitrogen in surface and subsurface flow tended to rise following conversion of grass and forest land.
Association Miscanthus reduced soil erosion more than switchgrass.
Association Miscanthus reduced nutrient loss more than switchgrass.
