Results of an orchard trial with new clonal sweet cherry rootstocks established at Holovousy and evaluated in the stage of full cropping

open access: yesHorticultural Science, 2007
Ten clonal dwarf or semi-dwarf rootstocks were evaluated in a trial that was established in the spring of 1999 at Holovousy. Lapins cv. was used as a scion tester for all these rootstocks; five of them were tested also by Regina cv.

Improving Intrinsic Water-Use Efficiency and Crop Yield

open access: yesCrop Science, 2002
Greater yield per unit rainfall is one of the most important challenges in dryland agriculture. Improving intrinsic water‐use efficiency (WT), the ratio of CO2 assimilation rate to transpiration rate at the stomata, may be one means of achieving this goal.

Flood-tolerant rice reduces yield variability and raises expected yield, differentially benefitting socially disadvantaged groups. [PDF]

open access: yes, 2013
Approximately 30% of the cultivated rice area in India is prone to crop damage from prolonged flooding. We use a randomized field experiment in 128 villages of Orissa India to show that Swarna-Sub1, a recently released submergence-tolerant rice variety ...
