Abstract/ Executive Summary:

The study investigated the yield performance of transplant aman rice cv. BRRI dhan49 and boro rice cv. BRRI dhan29 under improved package of cultivation (TEGRA) as compared to farmers’ practice. TEGRA is a rice farming practice which includes use of quality seeds and healthy seedlings, transplanting with rice transplanter, use of herbicide, use of balanced fertilization and micronutrients, and preventive plant protection measures. The study during transplant aman season included two treatments on rice cultivation method viz. TEGRA package and farmers’ practice while in boro rice four treatments viz. TEGRA package, farmers’ practice with high inputs, farmers’ practice with medium inputs and farmers’ practice with low inputs. The yield and plant characters of both transplant aman and boro rice were significantly influenced by the TEGRA package of cultivation as compared to farmers’ practice. TEGRA package of cultivation as compared to farmers’ practice increased the grain yield by 18.3% in transplant aman rice and by 80% in boro rice with less cost of production as compared to farmers’ practice, which eventually resulted 23% increase in gross return and 400% in net return. As a result, the benefit cost ratio of TEGRA package was much higher (1.35 and 2.20 during transplant aman rice and boro rice, respectively) compared to that of farmers’ practice (1.07 and 1.30).

Commodity: Rice

Objectives:

The present study was conducted to evaluate the growth and yield performance of transplant aman rice cv. BRRI dhan49 and boro rice cv. BRRI dhan29 under TEGRA package of cultivation and compare with farmers practices

Methodology:

The study was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh during the transplant aman season (July to November) in 2014 and boro season (December to June) in 2014-15 to ascertain the yield performance of transplant aman rice cv. BRRI dhan49 and boro rice cv. BRRI dhan29 under TEGRA package of cultivation as compared to farmers’ practices. The study during transplant aman season included two treatments on rice cultivation method viz. TEGRA package and farmers’ practice, while during boro season the experiment composed of four treatments on rice cultivation methods viz. TEGRA package of cultivation, farmers’ practice with high inputs, farmers’ practice with medium inputs and farmers’ practice with low inputs. To know about the farmers’ practice for transplant aman and boro rice cultivation, a questionnaire was prepared and collected from 20 farmers selected randomly from the village Boira, Mymensingh Sadar, Mymensingh and their cultivation practices such as seed collection, seedling raising technique, age of seedlings during transplanting, fertilizing dose and crop protection measures were noted. The experiments were laid out in a Randomized Complete Block Design (RCBD) with five replications with the unit plot size 10 m X 12 m to facilitate the use of rice transplanter. For TEGRA package, the seedlings were grown in tray with growing media of soil, ash and compost mixture and seedlings were transplanted using mechanical transplanter with 30 cm X 16 cm spacing. Growing of seedlings in the media is required for machine transplanting of the seedlings For farmers’ practice, seeds were collected from the farmers and the seedlings were transplated manually with 25 cm X 15 cm spacing followed by the farmers. Intercultural operations like gap filling, irrigations etc. were done as and when necessary. At crop maturity data on yield contributing characters were collected. Then grain yield was converted at 14% moisture and straws sun dried properly and then weighed. Data collected on different parameters were statistically analyzed using software, (MSTAT) and mean comparisons were made by Duncan’s Multiple Range Test (Gomez and Gomez, 1984).

Achievement/Findings:

From the results of the study it could be concluded that TEGRA package of rice cultivation is advantageous in terms of yield and cost of production of both transplant aman and boro rice under Bangladesh context. The technology might play a very vital role in increasing rice production in the country if it is adopted at farmers’ level successfully at large scale and therefore requires more research in this area.
