Evaluation of Argentine wild sunflower biotypes for drought stress during reproductive stage [PDF]
, 2012 As in several regions where sunflower production has moved to areas with limiting water availability, the search for water-stress tolerant genotypes has been intensified. Helianthus annuus ssp. annuus L.

The Role of Iron in Drought Tolerance
, 2023 Küresel iklim değişikliğiyle birlikte artan hava sıcaklığı ve düzensiz yağış rejimi tüm dünyayı kuraklık tehlikesiyle karşı karşıya bırakmaktadır. Önemli bir abiyotik stres kaynağı olan kuraklık, mahsulün kalitesini ve verimliliğini azaltmakta, dünya çapında gıda güvenliğini tehdit etmektedir.

American Journal of Agricultural Economics, EarlyView.Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Subsoiling with straw return optimizes the maize root system and water productivity
Agricultural Water ManagementLong-term conventional tillage exacerbates subsoil compaction, restricting root penetration and water and nutrient uptake. Although subsoiling is known to mitigate plough pan formation, the interactive effects of tillage and straw return on root system ...

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Selection indices to identify drought-tolerant grain sorghum cultivars. [PDF]
, 2017 Twenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block ...
