Rice is the most important and crucial to ensuring food and dietary energy security in most developing countries and is the staple food of more than half of the world's population. This study was conducted to identify the seed rate of hybrid rice varieties for mechanical transplanting during Boro (irrigated dry season), 2021-22 season at BRRI research field, Gazipur. Slender grain type BRRI hybrid dhan3, BRRI hybrid dhan5, Ishpahani hybrid dhan6, and BRRI dhan89 were used in the study. The same growth medium was used to establish mat-type seedlings on plastic trays (280 × 80 × 25 mm) at seed rates of 80, 90, 100, 110, and 120 g•tray −1 . Walk-behind type 04 rows rice transplanter (Daedong, model-DP 488) was used during transplanting in the field at the set of the plant to plant spacing of 140 mm while line-to-line spacing was fixed to 300 mm. The result depicted that regardless of the variety, seedling density increased linearly as seed rate increased, except for the 21 days following sowing. However, the seedling density of BRRI dhan89 decreased after the seed rate of 100 g•tray −1 due to mortality. The seedling height of the BRRI hybrids dhan5 and Ishpahani hybrid dhan6 was significantly higher than that of the BRRI hybrid dhan3 and BRRI dhan89. After 21 days, the seedling height decreased significantly with the increase in seed rate. For the seed rates of 100, 110, and 120 g•tray −1 , identical numbers of hills per unit area and plants per hill were observed. On the other hand, regardless of the variety, the percentage of missing hills considerably decreased with the increased seed rate. The yield of the BRRI hybrid dhan5 variety was significantly higher at the seed rates of 100 and 110 g•tray −1 , although the yield of the Ishpahani hybrid dhan6 variety was comparable. In terms of yield among the four varieties, BRRI hybrid dhan5 gave a higher yield followed by Ishpahani hybrid dhan6 while BRRI dhan89 gave a lower yield compared to the hybrid varieties irrespective of the seed rate. However, a

“…The productivity and efficiency of land and labour can be enhanced with effective mechanization. The need of the hour is to enhance the production and export of rice by making it globally competitive making full use of the available technologies to their maximum potential (Basir et al, 2020). Adopting innovations and modern technologies can help in boosting crop yield.…”

We conducted this study to analyze the adoption of Mechanical Transplanting of Rice (MTR) in one of the prominent rice-producing districts Gujranwala of Punjab, Province. Rice has been a significant source of income in this area. A total of 220 rice growers, were selected using the non-probability method of selection from Wazirabad and Kamoki tehsils of district Gujranwala. Selected respondents were interviewed face to face on a structured questionnaire which was pre-tested and validated before final data collection. Collected data were analyzed using Statistical Package for Social Sciences (SPSS). Results were distributed into three sections (i) demographic profile, (ii) relative advantage of MTR and (iii) constraints analysis. Demography unveiled that young age farmers had less inclination towards rice growing, although the majority of respondents had formal education, had ownership of their lands and farmers were irrigating rice crops using tube well. As for as relative advantage was concerned, MTR relatively produced a high extent in terms of effectiveness (X̅ = 4.04, SD=0.62) due to high efficiency, less labour intensive, and high yield. Mandatory use of lesser land levellers, maintenance issues of MTR, unskilled labour and inadequate training for the farmers were prominent consents aced by the MTR user. This study urges more technical backstopping from the concerned institutions to foster the adoption of MTR on the farm level.
