Many assessments of crop yield gaps based on comparisons to actual yields suggest grain in highly intensified agricultural systems are at or near the maximum attainable. However, these estimates can be biased situations where below full potential. Rice US continue increase annually, suggesting that rice not In interest directing future efforts towards areas improvement is most easily achieved, we estimated potential and production systems, which amongst highest yielding globally. Zones...
Abstract Climate change is predicted to shift temperature regimes in most agricultural areas with changes expected impact yields of crops, including rice. These temperature‐driven effects can be classified into point stresses, where a event during sensitive stage drives reduction yield, or seasonal warming losses, raised thought increase maintenance energy demands and thereby decrease available resources for yield formation. Simultaneous estimation the magnitude each effect on has not been...
Accurate estimation of a crop's yield potential (Yp) is critical to addressing long-term food security via identification the exploitable gap. Due lack field data, efforts quantify crop typically rely on models. Using ORYZA rice model, we sought estimate Yp irrigated for two widely used varieties (M-206 and CXL745) in three major US rice-producing regions that together represent some highest yielding world. Three issues with model had be addressed achieve acceptable simulation Yp; first,...
Efficient management of rice (Oryza sativa) nutrition across soils ranging from organic to mineral varies widely because large contributions nutrients, including N, the indigenous supply. This study tested hypothesis that N supply (INS) would increase if soil carbon (SOC) content paddy increased, evaluated a wide range SOC content. The INS, defined as uptake omission plots, was estimated 54 plots over 3-yr period at two locations in Sacramento–San Joaquin Delta 6 232 g kg−1. Additionally, 10...
Core Ideas Dry pea yield, protein, and resistant starch varied greatly across Montana. Yield protein were mainly determined by environments. Resistant is controlled genetics to a great extent. Effects of drought index, growth period, seed size, weight on analyzed. Pea ( Pisum sativum L.) has long been an important component the human diet, providing excellent source protein. In addition its starch, especially (RS), received extensive attention in food industries recent years. We evaluated...
While our knowledge of the range survival that outmigrating juvenile Chinook Salmon experience in different routes Sacramento–San Joaquin Delta has increased recent years, few studies have focused on their during outmigration Yolo Bypass, Delta's primary floodplain. The Bypass floodplain provides valuable rearing habitat and growth benefits to fish flood efforts are underway improve access Toe Drain, its perennial navigation channel, under a broader flows river stages than is currently...
Abstract We introduce artemis, a new package for the R statistical programming environment designed to analyze quantitative polymerase chain reaction (qPCR) data from environmental DNA studies. The artemis directly addresses several challenges analyzing eDNA survey data, including censorship of generated by qPCR analysis. performance models is compared with commonly used regression approaches using both simulated and experimental data. demonstrate that in have favorable characteristics...
