The monkey business hurts our health

PHI(pre-harvest interval)-Refers to the time one needs to wait before utilizing/eating/harvesting a crop already sprayed by the chemical
RI(Repeat interval)-refers to the time one needs to wait before a repeat spray of the pesticide.
in the most simplest term……..
PHI-is an indication of the time taken for the poison to be less harmfull to the human body
RI-an indication of the time taken for a chemical to be less harmfull to the pest
Some farmers think that a chemical with a shrt PHI are less effective – this is not very true!
Both PHI and RI are indicated on the chemical.the most contentios one for the farmer is the RI
Farmers ask:If the pest pressure is High, do i really need to adhere to the RI?
which is importand to observe? RI or PHI?
My take: RI if not so well observed will eat into your ROI
PHI if not observed will eat into our health
what is your take?


“It is like shooting your customer once he leaves your shop’’-Amstrong nyarigu(agribusiness student at Laikipia University)
Recent survey by agroinfokenya team has founfd that farmers are engaged in a dangerous practice,dangerous in the sense that it puts US (me,you and him/her) at risk.
The overuse of pesticides witnessed is either being done unknowingly,in the fear of loosing their investment to the pests and diseases or due to unproffesional advise in the quest to make sales by the agrodealers.
It is important for every agripreneur to, not only steer the wheel of agri-investment towards the profit road but also look into the ethical side-mirror and avoid the overlaps that are in the longtime destructive to the consumer health-do not kill your clients after the first sale!
It is prudent for any farmer to not only rely on the spoken word but also read the instructions carefully;this will not only help in achieving the the above mentioned ,but also shield the farmers from unnesesary costs which dig deep into their ROI.

It is advisable to try and compare your crop protection costs if you are doing crop X (eg Water melon) with your farmer friend doing the same crop in the vicinity.Asking yourself questions such as….why are your costs difference so huge? Can work wonders.
Agroinfokenya team of agronomists can always be contacted for any clarification on crop protection strategies including alighning your current crop protection callender to manage your costs.
Do you have any experiences on this?

Ask your Agronomist: Your sorghum yield should grow if you follow this fertiliser regime

Friday July 21 2017

Catherine Wanja, a sorghum farmer in Embu County samples the sorghum crop planted in her farm which is used as a demonstration plot, during a past farmers’ field day. Sorghum can tolerate drought conditions better than other crops due to its well developed roots and small leaf surface area which has a waxy layer and folds inwards during high temperatures to reduce transpiration.

In Summary

•Sorghum requires deep well drained fertile soils.
•Sorghum can tolerate drought conditions better than other crops due to its well developed roots.
•Topdressing fertiliser should be applied when the crop is knee-high.
•Production for sorghum varies with variety ranging from 8T for Gadam and 12t for Serena.


Q: I have been growing sorghum for the past two years but my production has been really low. I have tested my soils and results show I have good soils for sorghum but production is below 1,000kg per acre. Please help me improve my production.

Kennedy Magambo

Thanks for your enquiry, Mr Magambo. Sorghum is slowly becoming a crop of interest due to the fact that it can adapt very well in many regions of Kenya.

Sorghum can be used as food (either as grain or flour) or for brewing beer. The two are the driving force of many farmers adapting sorghum in Kenya, and the returns are good when production is equally great.

Now that we have farmers who are thinking agri-business and looking at making money from sorghum cultivation, we can now look slightly deeper into sorghum production.

What nutrients are key in sorghum production, and is fertiliser use in sorghum production important?

Growth Requirements

Sorghum requires deep well drained fertile soils. This will enhance root growth and expansion for better uptake of moisture in the soil, the best soil pH being 5.4 – 8.4.

Seedings should be done when soils are moist enough to enhance uniform germination.

High temperatures do affect flower initiation and development, which in turn affects overall sorghum production.

Sorghum can tolerate drought conditions better than other crops due to its well developed roots and small leaf surface area which has a waxy layer and folds inwards during high temperatures to reduce transpiration.

Fertiliser Requirements
For optimal yields, it is important to understand the requirements of the crop. Sorghum requires several key nutrients for maximum productivity.

These are Nitrogen(N), Phosphorus(P), Potassium(K), Sulphur(S), Magnesium(Mg), Zinc (Zn), Calcium(Ca) and to some extend Manganese(Mn) and Copper(Cu).

Farmers should apply NPK fertiliser with at least six combinations of the above nutrients (including the NPK) for maximum production.

NPK fertilisers with ratios (N=20-24, P=9-11.5, K=4.5-7) including S, Mg, and Zn give the best combination ratio for sorghum production.

Fertiliser application for NPK is best done in two splits for better yield production. The recommendation would be to do a rate of 75kg per acre at planting and 50kg per acre at topdress.

Topdressing fertiliser should be applied when the crop is knee-high.

In every crop planted, please ensure you use certified seeds and follow good agricultural practices in order to realise maximum benefit of investing in high quality fertiliser.

Production for sorghum varies with variety ranging from 8T for Gadam and 12t for Serena.

I wish you the best as a farmer and please invite me for a cup of uji made from sorghum after the harvest.

Anyone with an eagle eye on the social media platforms advocating for agricultue development must have noticed one trend of late….. The increase of silence and the reduction of posts inclusive of farm selfies.
Talking to several individuals,it seems the realities of agriculture has struck ,and the strong willed enterpreneurs are still soldering on in silence whereas the Quick -cash-netters are scampering for financial safety having exhaused a good percentage of the resources allocated for the veture before the ‘Mind-inserted profit making Exell formulas could materialize”.
On the other end,all the ‘Know it all Agronomists not in tandem with the realities seem to have gone silent after the vagaries of weather superceeded their technical expertise,not that they have Exited the groups,but ,they too are following the coments with neither a ‘F’ nor a Like in the comments….they have let their eyes do the talking.
Times have been tough yes,But it seems the finger licking moment for some is also here-Ask those selling watermelons now…if they are honest,they would say that they wish the current scenario remains constant.
A roasted cob of maize on the roadside is now at 50kes in kiboko as well as ksh 50 in limuru!! the farmgate price is now mouth watering!,this means that,the Fall army worms have favoured some farmers pockets and accounts!
As seen in one of the posts in a leading agro group,one member sought to count the farmers still going strong by them ‘raising up their hands’ with a like or a comment……..what happened next….your guess is as good as mine
As always,we encourage farmers to DO FARMING and NOT to TRY farming.
We encourage all farmers soldiering on to SOLDIER ON as the future is bright.
