Disentangling the Roles of Plant Water Status and Stem Carbohydrate Remobilization on Rice Harvest Index Under Drought [PDF]

Rice, 2023
Background Harvest index is an important component of grain yield and is typically reduced by reproductive stage drought stress in rice. Multiple drought response mechanisms can affect harvest index including plant water status and the degree of stem ...

Field and in-silico analysis of harvest index variability in maize silage. [PDF]

Front Plant Sci, 2023
Maize silage is a key component of feed rations in dairy systems due to its high forage and grain yield, water use efficiency, and energy content. However, maize silage nutritive value can be compromised by in-season changes during crop development due to changes in plant partitioning between grain and other biomass fractions. The partitioning to grain

Inheritance of harvest index in common bean [PDF]

Crop Breeding and Applied Biotechnology, 2018
The aim of this study was to verify if the harvest index (HI) of common bean is higher in modern lines, to verify if its estimate varies with the cycle of the plant and environmental conditions, and to obtain information concerning its genetic control ...

Diversity increases yield but reduces harvest index in crop mixtures. [PDF]

Nat Plants, 2021
Resource allocation to reproduction is a critical trait for plant fitness (1,2). This trait, called harvest index in the agricultural context (3,4,5), determines how plant biomass is converted to seed yield and consequently financial revenue from numerous major staple crops. While plant diversity has been demonstrated to increase plant biomass (6,7,8),

Crop management techniques to enhance harvest index in rice [PDF]

Journal of Experimental Botany, 2010
A major challenge in rice (Oryza sativa L.) production is to enhance water use efficiency (WUE) and maintain or even increase grain yield. WUE, if defined as the biomass accumulation over water consumed, may be fairly constant for a given species in given climate. WUE can be enhanced by less irrigation.

Linking phenology, harvest index, and genetics to improve chickpea grain yield. [PDF]

J Exp Bot
Abstract Phenology is critical to crop adaptation. We grew 24 chickpea genotypes in 12 environments to analyse: the environmental and genotypic drivers of phenology; associations between phenology and yield; and phenotypes associated with allelic variants of three flowering related candidate loci ...

Sink Strength Maintenance Underlies Drought Tolerance in Common Bean

Plants, 2021
Drought is a major limiter of yield in common bean, decreasing food security for those who rely on it as an important source of protein. While drought can have large impacts on yield by reducing photosynthesis and therefore resources availability, source

Determination of Damage Index of Olive Fruit (Koroneiky variety) in Different Harvesting Methods and Times in Golestan Province [PDF]

Journal of Agricultural Machinery, 2019
Introduction Olive is one of the plants, that has been cultivated for long in Iran. The average extracted oil is about 65 kg per tree. Four to five kg olives give approximately one liter oil.

Characterization of Young Shoot Population, Yield, and Nitrogen Demands of Tea (Camellia sinensis L.) Harvested under Different Standards

Horticulturae, 2022
The quality of green tea is greatly influenced by the harvest standards for young shoots. The present field experiment was conducted to characterize the young shoot populations, yields, and nitrogen (N) demands of tea plants subjected to four different ...

Analysis of Solanaceae Species Harvest-organ Growth by Linear Increase in Harvest Index and Harvest-organ Growth Rate [PDF]

Journal of the American Society for Horticultural Science, 2005
Crop growth simulation models have been mainly developed to simulate final yield reliably. Thus, a main challenge in these models is the definition of a stable method for expressing the growth of harvested organs (e.g., fruit, seed, tuber, etc.).
