Vector Quantized Spectral Clustering applied to Soybean Whole Genome Sequences [PDF]

arXiv, 2018
We develop a Vector Quantized Spectral Clustering (VQSC) algorithm that is a combination of Spectral Clustering (SC) and Vector Quantization (VQ) sampling for grouping Soybean genomes. The inspiration here is to use SC for its accuracy and VQ to make the algorithm computationally cheap (the complexity of SC is cubic in-terms of the input size ...

Effect of risk and incentives on contracts: The case of farm operators in Iowa

Agribusiness, EarlyView.
Abstract Longitudinal data on Iowa landowner–operator contracts are used to examine how the mean, variance, and skewness of expected farmland returns affected contract terms from 2008 to 2019. To control for unobserved operator risk preferences and ability as a fixed effect, the sample includes operators with multiple contracts.

Supply chain risk in grain trading: Inventories as real options for shipping grain

Agribusiness, EarlyView.
Abstract Integrating trading and logistics is an important challenge in commodity trading. Trading and logistics are strategic decisions and are integral to most commodities including grain shipping by rail, in addition to other modes (barges, ocean shipping). There are substantial risks, such as the ordering and placement of rail cars.

Soybean pod and seed counting in both outdoor fields and indoor laboratories using unions of deep neural networks [PDF]

arXiv
Automatic counting soybean pods and seeds in outdoor fields allows for rapid yield estimation before harvesting, while indoor laboratory counting offers greater accuracy. Both methods can significantly accelerate the breeding process. However, it remains challenging for accurately counting pods and seeds in outdoor fields, and there are still no ...

An investigation of the price discovery role of futures markets: A dynamic time warping analysis of the United States corn markets

Agribusiness, EarlyView.
Abstract Futures markets are critical to price discovery and often dominate spot markets. We analyze the linkages between daily corn futures and spot prices in the United States using dynamic time warping. This nonparametric pattern recognition technique has several advantages over traditional time series methods.

Impacts of geopolitics and policy on Latin American biodiversity and water resources

Agribusiness, EarlyView.
Abstract Latin America is a major agricultural producer with important natural resources. Efforts have been made to protect sensitive areas but are hindered by agricultural trade disruptions outside the control of individual countries due to globally integrated crop markets.

A Leaf-Level Dataset for Soybean-Cotton Detection and Segmentation [PDF]

arXiv
Soybean and cotton are major drivers of many countries' agricultural sectors, offering substantial economic returns but also facing persistent challenges from volunteer plants and weeds that hamper sustainable management. Effectively controlling volunteer plants and weeds demands advanced recognition strategies that can identify these amidst complex ...

Relationship of soybean and soybean meal quality

, 2020
Since the mid-1970s, the U.S. acreage for growing soybean, the average soybean yield per acre, as well as the average soybean meal production per year have been increasing; however, the U.S. has continued to lose world trade share for those commodities since the mid-'70s.

The Relationship Between Interest Rates and Agricultural Commodity Price Dynamics

Agribusiness, EarlyView.
ABSTRACT The U.S. Federal Reserve has undertaken several interest rate interventions in the past decade. This study explores the relationship between U.S. corn and soybean prices and Federal Reserve monetary policy interventions, in the short and long run.

Examining the Impact of Row Planting on Labor Use for Sustainable Food Production Among Maize Farmers in Rural Ghana

Agribusiness, EarlyView.
ABSTRACT Smallholder farmers are reverting to traditional production methods due to the high opportunity costs and unintended consequences of new technologies. This study focuses on row planting technology, which is labor‐intensive and slow without mechanized operations.
