Abstract/ Executive Summary:

In course of improving crop production systems, screening for improving varieties for new areas is necessary to address thesoil and environment. Hence, a total of seven separate field trials were conducted at farm farmer's field in Sylhet areas for the two consecutive crops seasons of 2017-18 and 2018-19, respectively to evaluate the performance of improved varieties with the existing cultivars at farmers' field. Each experiment was laid out in randomized complete block design with six dispersed replications. The unit plot size was varied with experiments. The result showed that improved varieties of different crop sviz., lentil („BARI Mosur-6), black gram (BARI Mash-3), chickpea (BARI Chola-6); potato (Diamant), turmeric (BARI Holud-4), maize (BARI Hybrid Maize-9) and flower gladiolus (BARI Galdiolus-4) performed better under the soil and climatic conditions of Sylhet region.

Keywords: Maize, Potato, Gladiolus, Turmeric, Lentil, Chickpea, Linseed, Acidic soil

Location: Surma-Kushiyara Floodplain of Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Non-commodity: Performance

Objectives:

To evaluate the yield performance of improved varieties of aforesaid crops with the existing cultivars at farmers' field of the Sylhet region.

Methodology:

A total of seven separate trials were conducted at farmer's field in Sylhet areas for two consecutive crops seasons of 2017-18 and 2018-19 to evaluate the performance of improved crop varieties with the existing cultivars at farmers' field. The study areas are located at Latitude 24°29' N and Longitude 91°39' E under the Surma-Kushiyara Floodplain of Bangladesh. The soil of experimental plots was non-calcareous gray with low organic matter content (1.23%), low soil pH (4.5-5.4), very low total N (0.06%), low content of P (9.46), K (0.14) and S (10.07) whereas Zn (1.13) and Boron (0.51) medium and optimum, respectively. Each experiment was laid out in randomized complete block design with six dispersed replications. The unit plot size was varied with the experiments. The average climatic data of Sylhet shows that the mean annual minimum temperature is 11.55 ⁰C and the mean annual maximum temperature is 34.23 ⁰C and the annual mean temperature nearly 17.54 ⁰C. Rainfall of the area is uni-modal, usually occurring during April to October, and total annual rainfall reached to 4217 mm; whereas in January, no rain at all and the lowest amount of rainfall occurred in December followed by November. However, in the rest of the months, total rainfall was ranged from 100 to just below 800 mm. Rainfall increased gradually from March and continued up to October.
