Grain Yield Mapping: Yield Sensing, Yield Reconstruction, and Errors
Precision Agriculture, 2002Research findings are reviewed focusing on yield sensing methods, yield reconstruction, mapping, and errors. Yield sensing methods were explained and yield mapping process was briefly introduced. Grain flow through different combines was explained and the effects of combine dynamics on yield measurement accuracy were discussed.

Interrelationships between Panicle Weight, Grain Yield, and Grain Yield Components in Oat
Crop Science, 1991The value of panicle weight as a selection criterion for improving grain yield in oat (Avena sativa L.) is largely unknown. Panicle weight in oat combines two of the three primary yield components, spikelets per panicle and seed weight, into a single trait that is easy to measure. Three oat populations were evaluated in 1987 through 1989 for the effect

Screening Yield Monitor Data Improves Grain Yield Maps
Agronomy Journal, 2004Yield monitor data contain systematic and random errors, which must be removed for creating accurate yield maps. A general procedure for assessing yield data cleaning methods was applied to a new postprocessing algorithm in which six common types of erroneous yield monitor values were removed: (1) combine header status up; (2) start‐/end‐pass delays ...

Automated Grain Yield Behavior Classification
JOM, 2019A method for classifying grain stress evolution behaviors using unsupervised learning techniques is presented. The method is applied to analyze grain stress histories measured in situ using high-energy x-ray diffraction microscopy from the aluminum–lithium alloy Al-Li 2099 at the elastic–plastic transition (yield).

Grazed Wheat Grain Yield Relationships
Agronomy Journal, 1991AbstractIrrigated wheat (Triticum aestivum L.) in Texas is grown in early‐planted production systems that are grazed by stocker cattle (Bos spp.) and late‐planted nongrazed production systems. The objectives were to: (i) verify cultivar ✕ production system interactions for 11 cultivars in 1988 and (ii) better understand grain yield relationships using ...

Agronomy Journal, 2006
Rice (Oryza sativa L.) breeders have historically not included nitrogen utilization efficiency (NUE) as a selection criterion in breeding for cultivars, even though it has economic and ecological implications. This study examined the significance and magnitude of variation in N content, NUE, N translocation ratio (NTR), and grain protein concentration ...

Wheat yields: Doubling-up on grain numbers
Nature Plants, 2015Modulating the expression of two flowering-genes can be used to produce wheat spikes with modified spikelet arrangement and higher grain number.
