    Are Fertilizer Use Returns Optimal In Kenyan Farms?

    Background information While many approaches, such as nutrient omission trials, have been shown to be beneficial in adjusting fertilizer recommendations such as nitrogen (N) fertilizer-based rates, severe nitrogen deficiencies persist across Kenyan farms. These can be attributed under application of N, or N loss. A large amount of the applied N is lost due to […]

    Integrated Soil Acid Management (ISAM) Approaches For Increased Soil Nitrogen Availability and Productivity

    In many places of the world, soil acidity is a substantial constraint to soil productivity. Sodium, aluminum, manganese, and hydrogen ion toxicity, as well as deficits in critical elements such as nitrogen, calcium, magnesium, phosphorus, and molybdenum, all contribute to plant growth suppression. Agricultural management practices have increased shifts in soil pH, raising concerns about […]

    22.5 Bags Of Maize From 0.42 Acres – Hope For Farmers Across The Country

    The trials team certainly had high expectations for their Nakuru Maize Variety Trial, but this extraordinary average yield certainly opened their eyes. The Nakuru site is just one of the 8 sites across the country that we’ve test varieties in different climates over the past 12 months. Had we grown the top-yielding variety in this […]

    Get The Best From Sunflowers & Herbicides

    Sunflowers are a fantastic crop for Kenya and can provide extra income for farmers in the off-season as well as many rotational benefits to the soil. But to get top yields it is crucial to check on your herbicides and keep the crop free from weed competition for the first 6-7 weeks. Good planting ensures […]

    Fall Armyworm Update – 22nd July 2020

    For the past three seasons growers have been reporting Fall Armyworm in the tips of cobs from silking right through to maturity, with damage at harvest similar to the photo below. Fall Armyworm numbers have clearly been on the decline since they first arrived in 2017, with some exceptions, and this year they appear to […]

    Choosing Wheat Varieties For That Big Crop

    With malting barley plantings down considerably this year, many farmers will be growing extra acres of wheat to make up for the area lost. But what varieties should you grow to manage the risks of a big wheat area? Robin Still yields very well in our trials, and most importantly of all is consistent across […]

    Is Fall Armyworm Falling Away?

    Think Agronomy 15th May 2020 If you set out to collect several hundred Fall Armyworm larvae for an experiment, I can tell you that it is a long task, which seems to take longer each year. Sure, if you look for them they are easy enough to find in fields that have perhaps not received […]

    Weed Control in Maize Farming

    As crops progress through the growth stages, weed control in maize up to 7-8 leaf stage is crucial to avoid yield loss. There are a number of maize herbicide options on the market, so we explore their strengths and their weak points… Stellar Star Stellar Star is very strong on Gallant Soldier, Datura and Mexican […]

    Maize Plant Populations

    Maize plant population and seed rate comparison data from our maize variety trial sites has been very enlightening. Last week we looked at the results of our Cropnuts Maize Variety Trials in 2019 and highlighted how some maize varieties perform very differently at higher plant populations. Within the Variety Trials last year at every site, […]

    Latest Insights From Our Crop Field Trials

    Importance of Molybdenum & Cobalt On Legumes Looking back through some of our legume crop field trials which have focused mainly on peas, the use of molybdenum and cobalt on the seed has consistently shown improvements in nodulation and yield. We know how important molybdenum is on legumes and brassicas in most Kenyan soils so […]

    Crop Fungicide Guide

    Fungicides are biocidal chemical compounds used to kill parasitic fungi or their spores. Fungi can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit. Fungicide Classification Fungicides are mostly known by their brand names. But when you want to get scientific about farming, it’s important to understand a bit more about which ones to use in different crops, and […]
