Introduction

Roots and tubers, notably potatoes, cassava, sweet potato
and yam are among the most important crops.
They play a critical role in the global food system,
particularly in the developing countries (Ochieng’, 2007;
Rosegrant et al. 2000).
Potato being an important food crop in Kenya employs
over 2.5 million people along it value chain (Songa, 2010).
The potato market in Kenya lacks a well defined structure
and it faces various limitations that require urgent redress.
Potatoes are mainly consumed when boiled, fried or
mashed.
Urban inhabitants are the major potato consumers.

Beyond farms, potato industry employs thousands as market
agents, transporters, processors and vendors.
Crop value at consumer prices is more than KSh.10
billion/year (currently 1 USD = Ksh. 78).
Fresh potato market is a major source of raw materials for
processors; the small-scale crisps processors in Kenya.
The processors often complain of scarcity of good quality
raw potato tubers.
An explanation has not been given from the producers or
sellers’ point of view.
This study aimed to characterize potato sellers in terms of
location, volume of sale, customer base, sources of
information, variety most traded, demand and supply
variations and handling practices by the traders.
Materials and Methods

This study was carried out between March and April 2010.
Nairobi and Nakuru cities were purposively selected for the
study since they have large number of markets that sold
potatoes intended for processing.
The sellers’ sample size was determined according to Nassiuma
(2004).
A total of 169 potato sellers were surveyed, data was collected
using a structured questionnaire.
Data were analyzed using SPSS version 11.5.
Chi-squire analysis was performed to check if there were any
hidden relationships.
Results and discussions
• 25 % of the respondents were located in Nakuru town and 75 %
in Nairobi.
• 70 % depended on fresh potato trade as the only source of
income compared to 30 % who also had additional sources.
• The average daily sales was 200 kg; in monetary value ranging
from Ksh. 5000-31,500. (currently 1 USD = Kshs. 78).
• Traders acquired fresh potatoes in 110 kg bags at average price of
Kshs. 1, 650; range Kshs. 800-4500.
• Use of extended bags: 20-180 kg at KSHs. 1,000 -6,000 reported.
• The traders then sold the fresh potatoes in the same units or
repackaged them into smaller units.

The unit sale and average costs of fresh (ware) potatoes are in
Table 1.
Prices are significantly (P ≤ 0.05) low during high supply
(harvesting) and highest during low supply seasons.
Demand varied highly (99 %) with seasons and was significantly
(P ≤ 0.05) correlated (r= - 0.96) to the supply (Figure 1).
The main customers were individuals who bought the produce
for home consumption.
Other customers included wholesalers and small-scale processors
(23 %) and outside catering (21 %); kiosks and supermarkets were
the least buyers at 3 and 0 %, respectively.

Varieties traded were Cangi (42 %), Tigoni (27 %), Dutch
Robjyn (8 %), Roslin Tana (8%) , Nyayo and Meru (4 %).
Sources of information on improved technologies and
available varieties in the market were found to be varied
(Figure 2).
Researchers need to improve their relationship with traders
in post-harvest handling and storage of fresh potatoes.
60 % stored fresh (ware) potatoes for 1-3 weeks in gunny
bags at their premises.
Most traders exposed potatoes to sunlight oblivious of the
danger posed by greening the produce.
Most traders (89 %) reported storage losses due to rotting
(69 %) and greening (31 %) while 11 % reported no loss.
Care is needed on selecting potatoes, green ones ought to be
avoided (Kabira and Lemaga, 2006).

Conclusions and recommendations






A majority of fresh potato sellers were located in Nairobi
while a few were in Nakuru.
A large number of respondents traded in potatoes as the
only source of income.
Demand for fresh potatoes by customers is highly
dependent on seasons being low during the harvesting
seasons.
Most traders stored fresh potatoes for short periods in
gunny bags at their premises; losses due to rotting and
greening were reported.
Traders lacked proper skills of handling and storage of
fresh potatoes which are needed to prevent such losses.
The gap in potato handling and storage skills could be
bridged through appropriate training of the traders.
