Maize silage Easy to establish and reliable, maize produces a very palatable and high-energy silage provided that it is well chopped and ensiled properly. Typically over 11 Mj of metabolisable energy per kilo, it is a great way of storing crop to feed for livestock later. The main drawbacks are that it needs to be […]

As we approach the potato planting season, good planning is essential to achieve the best from the crop and maximise your profits. We take a look at the steps to consider: Number 1 is certified seed; you do not need the crop to be held back by diseases such as Blackleg, Black Dot, and Rhizoctonia […]

Legumes for a crucial part of the crop rotation on many levels, adding valuable soil nitrogen, reducing root diseases such as Take-all and Fusarium in cereals, improving soil structure and allowing control of grass weeds such as Brome and Ryegrass. Something that I have seen first-hand over the last few years in Kenya is the […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 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, […]

Choosing the right variety is important for any crop, but with a crop like maize where there is just so much choice, where do you start? Last season we carried out four fully replicated maize variety trials in the highland areas; in Timau, Rumuruti, Nakuru and Eldoret to independently compare a range of maize varieties […]

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 […]

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 […]
