INTRODUCTION PROMOTION OF IMPROVED NARROW CRIB USING LOCAL MATERIAL FOR MAIZE STORAGE AS A REMEDY AGAINST POSTHARVEST LOSSES IN MAIZE PRODUCTION PRESENTED BY ANTI STEPHEN ON BEHALF OF GROUP 2B
Postharvest management in maize production plays a vital role in agriculture. • Improper postharvest management causes loss of considerable quantity of maize produce. • This results in the sizable gap between gross production and net availability of maize. • Absolute lack of postharvest management also causes crisis in maize production. • However, there are a number of ways of managing postharvest lost in maize production.
But the cost of implementation is another factor of difficulties. • Besides, the most affordable and improved method of reducing postharvest lost in maize production is the narrow crib. • Narrow crib is a type of granary used to dry and store corn for a longer period of time. • It is the cheapest method of reducing postharvest loss in maize production. • It can be constructed using locally available resources where the peasant farmer can afford.
OBJECTIVES The main objectives of promoting the use of improved narrow crib are: • To store maize for a longer period. • To reduce the cost of postharvest management in maize production. • To dry and allow frequent air circulation.
To reduce pest infestation of harvested maize. • To reduce losses after harvesting. • To sell maize at the right time for better price. • To increase supply throughout a specific year. • To enhance better quality food.
IMPLEMENTATION The implementation procedure of the study is as follows: • Training the farmers on the factors to consider when selecting site for crib construction with the group. • Teaching the farmers on the importance of narrow crib construction
Taking the farmers through the procedure of construction. • Pictorial demonstration on narrow crib construction. • Speaking the language that is best understood by the farmers.
MATERIALS The following materials are needed for the construction: • Strong fogged sticks • Strong splitted bamboo • Rail guards
Ropes/nails • So lignum • Earth chisel and cutlass • Tape measure • Marker
PROCEDURE • Dug holes of about 0.5m • Treat the fogged sticks and bamboo against weevil attacks • Put fogged sticks of 2.5m in the holes that is, 1m high from the ground • Put 3.5m sticks which form the structure of the crib with the sticks which form the platform in the 0.5m hole. • Use the bamboo to form the platform of the crib
Cover the sides of the structure with bamboo from the platform upwards to roof level.
Provide a good space for easy loading and off-loading in the crib. • Use rodent guard on all the sticks from the ground forming the crib stacked. • Width of crib should be 1.5m wide and length 6m long. The length however depends on the quantity of the grains to be stored.
