A target region amplified polymorphism marker for fertility restorer gene rf1 and chromosomal localization of rf1 and rf2 in cotton
Cytoplasmic male sterility (CMS), a maternally inherited trait characterized as an inability to produce functional pollen, is an important biological system for economically producing hybrid seed to enhance crop yield and studying cytoplasmic and nuclear gene interactions. In cultivated tetraploid cotton (Gossypium hirsutum L.), male fertility in two systems CMS-D2 and CMS-D8 is restored by two ...

Can pulse crops play a role in mitigating greenhouse gases from North American agriculture?
The atmospheric buildup of greenhouse gases (GHGs) is a serious environmental issue. Globally, agricultural activities are an important source of anthropogenic GHGs, contributing 20% of the annual atmospheric increase. Management choices largely determine if agricultural soils will be a source, a sink, or will be neutral with respect to GHG net flux. The proportion of agricultural land that is ...

Cuphea nitrogen uptake and seed yield response to nitrogen fertilization
Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton, PSR23) is an oilseed crop that is a rich source of medium-chain fatty acids. Progress has been made on improving cuphea agronomically, but little is known about N fertility requirements for optimum cuphea production. The objective of this study was to determine the N necessary for maximizing seed yield and oil content. Experiment 1 was ...

Cover Crop and nitrogen effects on maize productivity in no-tillage systems of the Brazilian Cerrados
Cover crops in direct seeding mulch-based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. We hypothesized that cover crops would optimize N supply to the maize ...

Seeding rate and planting arrangement effects on growth and weed suppression of a legume-oat cover crop for organic vegetable systems
Winter cover crops can add soil organic matter, improve nutrient cycling, and suppress weeds in organic vegetable systems. A 2-yr study was conducted on organic farms in Salinas and Hollister, CA, to evaluate the effect of seeding rate (SR) and planting arrangement on cover crop density, ground cover, and cover crop and weed dry matter (DM) with a mixed cover crop. The mix contained legumes (35% ...

The Importance of Leaf Area Index (LAI) in Environmental and Crop Research
Leaf Area Index (LAI), which is used as a measure in hundreds of studies on forests, crops, climate and the environment, is calculated as half the area of all leaves per unit area of ground. It is measured as the leaf area (m2 ) per ground area (m–2) and is unit-less. So, a plant with a LAI of 2 has an amount of leaves that can cover a given area two times. LAI is calculated for a plant or ...

Variable Rate Technology: What is it and what are the Benefits?
Every day, as ag professionals, the focus is on the day-to-day needs of the farm, regardless if you’re a farmer, a retailer, advisor, or service provider. We all think about how to answer questions like which seed will perform the best this year, will commodity prices will be favorable, or will this year finally be another golden year like 2008… But, one of the biggest questions is a ...

Getting seed to smallholders needs a business approach
A locally owned, alternative model of supplying affordable seed is working for Africa’s framers, says Joe DeVries. Smallholder farmers in Africa — mostly women — wage silent battles against the elements and other forces beyond their control to feed their families, their villages, their countries. They have historically taken the lead in feeding Africa and are destined to ...

Modern Miracles
When a technology comes along that unlocks a new way of thinking about an old problem, we marvel at it as a “modern miracle.” Growing up in Ireland, I know that memories of the Great Potato Famine still run deep. Today, Irish farmers know how fungicides have helped ensure that potato late blight remains a distant memory. Agriculture has come a long way since the nineteenth century, ...

Make the Most Out of Each Farmable Acre
Variable rate technology increases production and manage costs while reducing waste We farm in a time where working smarter, rather than harder, is essential to running a successful, sustainable business. There’s an incredible push in agriculture today for you to balance economics on the farm with environmental practices that keep farmland healthy for generations to come. The key to ...

Growing Industrial Hemp - Risks and Rewards
In 2013, Colorado became the first state in the US to legalize industrial hemp. The 2014 Farm Bill granted US farmers the right to cultivate hemp in states where production is legal and established hemp pilot research programs nationwide. Industrial hemp is grown for food, feed, fuel, building materials, and more. Traditional hemp, grown for mass market products such as textiles and bioplastics, ...

Managing fertilizer’s salt effect in drought
During drought or dry conditions, salinity and pH levels can change quickly in the soil. While the forecast shouldn’t entirely dictate how you manage your farm, understanding and performing the best farming practices when adding seed-placed nutrients can help save your yields when the rain fails to ...

One crop, two ways, multiple benefits
Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

Soil phosphorus
As I "dig" deeper into the soil microbial world I am amazed how much we understand but few utilize what we do know. The word is getting out that if we let the soil microbes thrive and multiply by feeding our soil degradable plant and organic material the microbes will give our plants and crops back the nutrients they need. We are now finding that by adding fertilizers directly in the inorganic ...

How seed-placed fertilizer may hurt your crops if not applied carefully and attentively
Placing fertilizer within the seed row has been long-standing practice for many farmers across the prairies. Having those nutrients close to the seed makes it easily accessible by the plant, and can help the crop out of the ground and into the sun. Potash fertilizers and other nutrients, such as phosphate, are immobile fertilizers, meaning they don’t travel more than a half-inch through ...
