Abstract/ Executive Summary:

To increase the production yield gap to be reduced to some extent. A study was conducted to determine the contribution of different crop management factors in narrowing the yield gap at farmer’s filled of FSR&D site, Moison, Kapasia during Boro season. Objective of this study was to determine the contribution of different crop management factors in narrowing the yield gap at farmers level. The result showed that in boro season, BRRI recommended management practices produced significantly higher yield which was about 47% higher than the farmer’s practice. An yield advantage of about 31% could be attained by using quality seed + recommended fertilizer while there were 25 and 9.9% higher than farmer’s practice when recommended fertilizer and quality seeds were used, respectively.

Keywords: Rice, Yield gap, Quality seed, Recommended management practice, Farmers practice

Location: Kapasia, Gazipur

Start Date: 01-07-2005

End Date: 30-06-2006

Program Area: Farming System

Non-commodity: Management

Objectives:

To determine the contribution of different crop management factors in narrowing the yield gap at farmers level

Methodology:

Yield gap of rice exists between researcher and farmer’s plot which is attributed to many factors, such as quality seed, use of over-aged seedlings, delayed planting, imbalanced fertilizer use, poor management practices and socioeconomic factors. A study was conducted to determine the contribution of different crop management factors in narrowing the yield gap at farmer’s filled of FSR&D site, Moison, Kapasia during Boro 2005-06. Three dispersed farmers’ filled were selected for this study. Each farmers’ filled was considered as one replication. Five management options were: i) Farmer’s practice (FP), ii) FP + quality seed (Qs), iii) FP + Recommended fertilizer (RF), iv) FP + QS + RF and v) All BRRI recommended management practices.

Achievement/Findings:

Yield and yield contributing characters were significantly affected by different management practices. BRRI recommended management practices produced significantly higher yield which was about 47% higher than the farmer’s practice. The result of the study revealed that an yield advantage of about 31% could be attained by using QS + RF (quality seed + recommended fertilizer) while there were 25 and 9.9% higher than FP (farmer’s practice) when recommended fertilizer and quality seeds were used, respectively.
