Abstract | Inorganic and organic fertilizer are important resources for rice production in Takeo
Province. Management of these resources was different among the farmers and between the
recommendation rate . This study was undertaken to examine the trend in inorganic and
organic fertilizer, perception of how inorganic and organic fertilizer effect the farm field and
the rice crop, management practice, and analysis why farmers adopt or reject innovation. The
survey results indicated that The popular kind of fertilizers used in the province were urea, 16-
20-0. Urea usually applies as a top dressing, while 16-20-0 usually applies as a basal
application. Farmers having large farm, higher saving, and higher economic status tend to use
low rate of fertilizer. The rate of fertilizer was high for dry season rice compared to wet
season rice. Most of fertilizers used in the province were from private sector. Only a very
small proportion was from government. Organic manure available in the farm was only
farmyard manure (FYM). FYM available in the farm was not adequate for rice cultivation. A
large proportion of cultivated area received little or no FYM. Farmers tend to apply FYM to
nursery, some to income- generating crops and the remaining was applied to the field.
Farmers perceived that inorganic and organic fertilizer have a good effect to rice crops and
the combination of them provides a better effects than applying separately. Management of
FYM and animal urine were rather poor in term of collecting, storing and incorporating to the
field. FYM usually applies before land preparation. Farmers adoption to fertilizer
recommendation was minimal due to lack of farm resource; information; extension, training
and credit service; farmers' knowledge; lack of rainfall and irrigation water. For improvement
of the situation recommendations have been provided. |
