Summary

Wheat is the second most important cereal crop in Bangladesh and can be cultivated in a wide range of environments. Average yield remains low in comparison to other countries. So far very little work has been done within Bangladesh to develop a package of improved management practices to increase wheat yields.

The objective of this study was to assess which of the three tested wheat varieties achieves the best grain yield in the respective location. In addition this trial served as validation trial for a research station experiment to create location specific information which has been lacking.

Wheat varieties were Shatabdi, Prodip and BARI Go27[1] were tested in a randomized complete block design (n=54) on farms participating in SAF-BIN project in Baraigram (Natore district), Paba (Rajshahi district) and Patnitala (Naogaon district). Each variety was provided to 6 farmers/location. Cultivation practices following BARI[2] recommendations were applied. Data on grain yield (t/ha) was collected and data from earlier trials (n=9) conducted at Rajshahi University were used. Descriptive statistics and variance analysis (ANOVA) were performed for the factors variety, location, replication and variety*location.

In the field trials both variety and location had significant effects on grain yield. Across locations Prodip produced the highest grain yield (range 3-4.8t/ha) followed by BARI Gom 27 (2.5-4,5t/ha) and Shatabdi (1.5-5t/ha). Prodip achieved the highest grain yield in Baraigram (3.8t/ha) and Paba (4.1t/ha). But in Patnitala Shatabdi was the highest yielding variety with 4.2 t/ha. The significant effect of replication shows heterogeneity of the replicated plots.

Based on grain yield Prodip has been identified as most suitable variety for the farmers in Baraigram and Paba and Shatabdi for farmers in Patnitala.
