Mixed Planting with Legumes Modified the Water Source and Water Use of Pearl Millet

Pearl Millet Growth as Affected by Phosphorus and Water

The interaction of soiil water and P supply is of paramount importance to pearl millet [Penniseturn gluucum (L.) R. Br.] growth in Sahelian Africa due to unreliable rainfall and low soil P availability. This study was conducted to quantify the growth response of pe:ul millet to water supply and P under conditions analogous to the Saliel in terms of climatle and soil. Millet was grown for 84 d i...

Impacts of Drought Stress and Planting Methods on Sweet Corn Yield and Water Use Efficiency

Abstract Seasonal drought is the most important factor to limit the production of maize in the world. Using a split plot design, a two year field experiment was conducted to determine the effect of limited irrigation regime on yield, yield components and water use efficiency of sweet corn (Zea mays var. saccharata). Responses of three sweet corn varieties KSC403, Merit and Obsession to three di...

Legumes are different: Leaf nitrogen, photosynthesis, and water use efficiency.

Using robust, pairwise comparisons and a global dataset, we show that nitrogen concentration per unit leaf mass for nitrogen-fixing plants (N2FP; mainly legumes plus some actinorhizal species) in nonagricultural ecosystems is universally greater (43-100%) than that for other plants (OP). This difference is maintained across Koppen climate zones and growth forms and strongest in the wet tropics ...

Constitutive water-conserving mechanisms are correlated with the terminal drought tolerance of pearl millet [Pennisetum glaucum (L.) R. Br.]

Pearl millet, a key staple crop of the semi-arid tropics, is mostly grown in water-limited conditions, and improving its performance depends on how genotypes manage limited water resources. This study investigates whether the control of water loss under non-limiting water conditions is involved in the terminal drought tolerance of pearl millet. Two pairs of tolerant x sensitive pearl millet gen...
