How to achieve high crop yields

January 28th, 2019 / Daily Monitor, Uganda

B4FA Fellow, Michael Ssali writes:

The ideas in today’s sharing about how to achieve high crop yields are mainly drawn from the “Think Agronomy” newsletter published by the Kenyan-based Centre of Excellence for Crop Rotation. 

In a simple experiment last year it was possible to produce 11.84 tonnes of barley from one …

CRISPR-edited rice plants produce major boost in grain yield

May 29th, 2018 / Purdue Agricultural News

A team of scientists from Purdue University and the Chinese Academy of Sciences has used CRISPR/Cas9 gene-editing technology to develop a variety of rice that produces 25-31 percent more grain and would have been virtually impossible to create through traditional breeding methods.
The team, led by Jian-Kang Zhu, a distinguished professor …

Does GMO corn increase crop yields? 21 years of data confirm say ‘yes’

February 20th, 2018 / Genetic Literacy Project, US

The analysis of over 6,000 peer-reviewed studies covering 21 years of data found that GMO corn increased yields up to 25 percent and dramatically decreased dangerous food contaminants. The study, published in Scientific Reports, analyzed field data from 1996, when the first GMO corn was planted, through 2016 in the …

Use of CRISPR systems in plant genome editing: toward new opportunities in agriculture

November 30th, 2017 / Emerging Topics in Life Sciences, UK

Initially discovered in bacteria and archaea, CRISPR–Cas9 is an adaptive immune system found in prokaryotes. In 2012, scientists found a way to use it as a genome editing tool. In 2013, its application in plants was successfully achieved. This breakthrough has opened up many new opportunities for researchers, including the …

Scientist’s tips on better banana yields

June 20th, 2017 / Daily Monitor, Uganda

B4FA Fellow Lominda Afedraru reports:
Dr Kenneth Akankwasa from Uganda’s National Agricultural Research Laboratories (NARL), takes us through the good agronomy practices.
• When preparing the field, farmers are expected to plant seedlings free of pests and disease.
• The site should have deep well-drained and fertile soils, preferably rich in organic matter …

Irrigation boosts banana yield by 30% in Kenya

April 4th, 2017 / Farmbiz Africa

Farmers, who regularly irrigate bananas, can boot the weight of the fruit by more than 30 per cent.
More than 90 per cent of famers in Kenya- especially in Nyanza and Central regions- do not know bananas have to be irrigated like other horticultural crops for high yields. Read …

Raising crop productivity in Africa through intensification

March 14th, 2017 / Agronomy, Switzerland

The population of Africa will double in the next 33 years to reach 2.5 billion by 2050. Although roughly 60% of the continent’s population is engaged in agriculture, the produce from this sector cannot feed its citizens. Hence, in 2013 alone, Africa imported 56.5 million tons of wheat, maize, and …

Agriculture in Africa: Potential versus reality

February 23rd, 2017 / How we made it in Africa

With more than 60% of its 1.166 billion people living in rural areas, Africa’s economy is inherently dependent on agriculture. More than 32% of the continent’s gross domestic product comes from the sector.
However, agricultural productivity still remains far from developed world standards. Over 90% of agriculture depends on rainfall, with …

How to grow more cassava

January 26th, 2017 / The Conversation, UK

Cassava is one of the most efficient producers of carbohydrates and energy among all food crops. It can produce more than 250,000 calories per hectare per day, compared to 176,000 for rice, 110,000 for wheat and 200,000 for corn.
But despite its widespread consumption, cassava yields have not improved in a …

Yield gaps – social aspects

January 12th, 2017 / Claudia Canales, B4FA

Yield gaps, the difference between actual production and what is potentially achievable under optimum growing conditions, are greatest in the poorer parts of the world, and these regions are also the ones that are predicted to be most vulnerable to the combined pressures of increases in population, the effects of …
