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.

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?

•Ask your Agronomist: You can grow these food crops with saline water
•Ask your Agronomist: Go for crop specific fertilisers for good yields
•Ask your Agronomist: When to apply foliar fertiliser for best results
•Ask your Agronomist: Use manure and mineral fertiliser for best results

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.


                           WHAT OF THE FAILED GREENHOUSES?

……Now we have Nunua ploti na greenhouse!!!!!!!

Before making any coments, i beg to direct my opinions on the following articles ,i dont mean they are not worth,but since they are in the public domain,why not disect the information?

With an investment of only ksh 120,000 one is “guaranteed” a return of ksh 1Million per annum! Farming then must be really lucrative! mathematically,one would only have to invest ksh 240.000 into two greenhouses to be assured of ksh 2M within the year,alternatively,secure a loan of ksh 600,000 with a repayment period of 4years ,invest in the greenhouses (4 of 8by 15M) and within a season,as per the links 1 he/she will repay the loan fully and continue leaving DEBT FREE!

I doubt,if any small scale farmer can ever break even by planting Onions in a miniature greenhouse or rather an 8M by 15M greenhouse

a farmer testiony as per this link is also encouraging and mouth watering ,


Agroinfokenya has come across so many greenhouses across the country that have now turned to be stores,the school greenhouse projects have been key into ensuring the teachers have a place where the students can store their school bags during exams! (why on earth does a reputable company construct a tunnell in the coastal region with No ventilation?!!

as you Drive,cycle,or walk home… many greenhouse structures do you see?  of all these,how many ,on closer look do you see a crop in it?….of all the ones with a crop in it,how many do you gauge have a serious crop in it?

We at Agroinfokenya pose the Quesion…What is the driving factor behid the failures of these projects? what are the companies involved in these projects doing to avert these? how many farmers have lost their investments as a result of the basic information provided to only encourage the farmer to Buy the structure?

The social media is awash with ”many would be millionaires” seeking buyers for their structures with a QUICK sale message,many have been demoralised yet many are still optimistic that something can be done in the right way,giving the right information and not just giving information TAILORED to Make sales.

we call upon the companies involved in these projects to MIND the customers,Mind the farmers as well as Protect the farmer investment by giving the right information at the right time and at the right costs.. after all,if the farmers fail,the sustainability of the projects /business is at risk as farmers will not Buy more.

We believe that proper attention is not offered to the small and medium scale farmers compared to the large scale farms ,after all,very few large scale farms have these problems due to unlimited access to information from these companies .

we at agroinfokenya seek to have the right information,we seek to convey this to the public without well,we seek to have the farming comunity shout at the top of their voice that It is NOT as it is said BUT as you want t to be..

we trust that with openess and honesty as displayed by such companies …,farmers will feel safe in the hands of professionals.

quoting from  ”TRUE,There is  MONEY in greenhouse farming. But it is not easy money, as the aggressive sellers of greenhouse technology would want farmers to believe.”

Kindly share your experiences , photos of FAILED greenhouses as well as those prospering to our page






Agriculture is Dynamic….very dynamic.I still picture a recent scenario where a farmer visited a shop in Nakuru and was seeking to be given AMBUSH, scenes of farmers coming to the shops with notes from agronomist prescribing some chemicals eg Bayleton(which have since been replaced by a different molecule by Bayer crop science) have not escaped my eyes too.

These indicate that each and every person involved in the industry has to be updated by the emerging trends to remain relevant either in the market or in the farm!

Agroinfokenya prides itself of a goup of agronomist with experience in several fields  as well as experience of agricultural dynamics agross the different regions/areas in the country.

we therefore seek your support in ensuring we diseminate the information we have in conjunction with the challenges faced by the farmer to the public for knwledge growth by sending us an email to>  with your questions,sugestions,advice or any relevant article you deem necesary for the general farmer domain.

kindly NOTE that agroinfokenya  does not accept any academic plagiarism ,thus any article from a member shall be duly acredited to him/her whereas any plagiarised material WIll NOT be published unless credit isgiven to the author.

if we dont have the full information you specifically need,we will link you to the people to answer



Our attention is directed to a recent post on social media (Twitter) (facebook)by  some concerned graduate in agriculture in kenya regarding unemployment.

The comments made by most people were eye catching and i beg to refer to some of them.

Noah M. M. Nasiali I think the problem is too much research and yet the practical part is not being managed.

What if you all formed an organisation to work with farmers to offer agronomic support.

Have an Uber-style working.
Get farmers to pay for services rendered either monthly or per season.

Epuri Lebasha Mr . Noah M. M. Nasiali I absolutely agree with you. I don’t know of the “don’t want to be employed in farms thing” coz over here, there is ideally more emphasis jn practical learning. 60% of EARTH U students go back to the farm etc. And an agronomist should be a farm lover anyway. Kenya Association of Agronomists still have miles to go. They ought to be maskio and macho of wakulima as well and farmers would never feel a negatively targeted group.

Agroinfokenya feels that the current system doesnt give the agricultural students an opportunity to realize exactly what it means to be “studying Agriculture or any related course,it ,to some extent demean the profession.

Why should the agricultural students get internship in goverment institutions where they are tasked with arranging files?

By giving the proffesion the attention it requires,then in no way will the graduates be seeeking for employment but will be seeking for employees.


Having some of the curent team of agronomists being victims of the system inadequacy in attention focus to the nobble profesion,the suggestion to have the agriculture students seek to get internship/attachment to both medium, small as well as large scale farms later on will inject into them the desire to be the change agents in the sector.Unfortunately,most of us want to get internship only in firms where we will be paid but not where we are given the opportunity to have a hands on experience in the farm.

After clearing college,how many of you will want to be employed as farm managers,how many will want to directly go to the farm and start production? how many will want to go to the office in a tie? if you are thinking of the later,then you better think Bet  ALREADY SAID IT

To the Institutions

Why cant we throw away the box and think without it being near us,the normal “project ” by the students which sometimes are not aligned to the current development in the sector can be restructured to have the funds dedicated to the students who can direct these into leasing a farm,planting the crop of their choice as well as managing this up to the market level .this will definately give the students a hands on experience in the sector where they may enjoy the money as well as hear the experience of their collegues who lost it during their presentations.
