The Analysis of Topping Results of Faba Bean Varieties (Vicia faba L.) by Using Logistic Nonlinear Regression Model [PDF]

open access: yesIkufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2017
Growth analysis is a valuable method to quantify crop growth, development and production. Because, parameters of nonlinear regression models have significant physiological meanings, it was decided to study the effect of topping and variety on crop growth

Determination of crop evapotranspiration of tea (Thea sinensis) using weighing lysimeter for the Nilgiris

open access: yesJournal of Agrometeorology, 2009
A long term experiment (1996-2001) was conducted for determining crop evapotranspiration (ETc) of tea (Thea sinensis) using weighing type lysimeter at the Central Soil and Water Conservation Research and Training Institute-Research Centre (CSWCRTI-RC ...

Soybean Yield Formation Physiology – A Foundation for Precision Breeding Based Improvement

open access: yesFrontiers in Plant Science, 2021
The continued improvement of crop yield is a fundamental driver in agriculture and is the goal of both plant breeders and researchers. Plant breeders have been remarkably successful in improving crop yield, as demonstrated by the continued release of ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The Growth Analysis of Corn (Zea mays L. cv. SC 604) With Different Fertilizers Application [PDF]

open access: yesIkufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2013
To investigate the responses growth indices of corn (Zea mays L. cv. SC 604) to using plant growth promoting rhizobacteria (PGPR) and phosphate solubilizing microorganisms (PSM) and rhizobacteria, a field experiment was conducted during 2008.

Climate change impact on China food security in 2050 [PDF]

open access: yes, 2012
Climate change is now affecting global agriculture and food production worldwide. Nonetheless the direct link between climate change and food security at the national scale is poorly understood.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Management of Plant Growth Regulators in Cotton Using Active Crop Canopy Sensors

open access: yesAgriculture, 2018
Factors affecting cotton development present spatial and temporal variability. Plant growth regulators (PGR) are used to control vegetative growth, promote higher yields, better fiber quality, and facilitate mechanical harvest.
