Mechanical transplanting and urea fertilizer deep placement into soil simultaneously with a walk behind type mechanical transplanter increased yield and benefit of wetland rice (Oryza sativa L.) cultivation in Bangladesh CIGR Journal
Hossen, Md. Anwar; Kamruzzaman, Md.; Islam, Md. Monirul; Rahman, Mohammad Abdur; Kabir, Md. Shahjahan.
AbstractA research was conducted to evaluate the BRRI developed rice transplanter cum prilled urea applicator (RTPUA) during Boro 2017-2018. Urea fertilizer deep placement mechanism successfully incorporated in the walk behind type rice transplanter (ARP-4UM). Engine power available at high rpm (more than 1800 rpm of the walking type rice transplanter) was conveyed to the applicator with the arrangement of a belt-pulley, worm gearing, shaft-bearing, chain-sprocket and bevel gear with engage-disengage facility resulting 22 rpm of the applicator main shaft considering transplanting speed of the transplanter. Impellor type mechanism was connected with the main shaft of the applicator to dispense the prilled urea fertilizer to the output channel. Field...

Effects of inundation period and tillage option on field performance of self-propelled rice transplanter CIGR Journal
Hossen, Md. Anwar; Hossen, Md. Anwar; Hossain, Md. Mosharraf; Bell, Richard W; Haque, Md. Enamul.
Manual transplanting of rice seedlings in puddling condition is a common method of crop establishment in the irrigated rice systems of Asia though it is time consuming. Rice transplanters are outmost need to overcome the labor crisis in the peak transplanting periods. But, self-propelled transplanter requires an ideal field conditions to obtain better performance. Hence, a self-propelled rice transplanter (Model: DP480 and S3-680) was evaluated in clay loam (CLS), loam (LS) and sandy loam soil (SLS) during the irrigated dry season (Boro) of 2012-13 and 2013-14 under three inundation periods of 12, 18 and 24 hrs and three tillage options as strip tillage (ST), zero tillage (ZT) and conventional tillage (CT) to identify a suitable inundation period and...

IDENTIFICATION OF PUDDLING SETTLING PERIOD OF VARIOUS SOIL TEXTURE FOR MECHANICAL RICE TRANSPLANTING CIGR Journal
Al Mamun, Muhammad Rashed; Islam, Md. Amirul; Lucky, Afroja Kabir; Hossen, Md. Anwar.
Primary satisfaction in seedling transplanting is a successful procedure of transplanting with mechanical rice transplanter. For rice cultivation puddling is generally done for a better transplanting. The study was conducted to characterize the optimum puddling settling period for various soil texture. The plots were prepared by following all the possible operations to provide a favorable field condition. Each plot was transplanted at eight different times for settling period of four to thirty two hours in clay, sand and silt textured soil. Primarily 76 hills in each plot, average planting depth 6 cm and seedlings density was found seven from each field. The transplanting performance character was found in different values. It was observed that percentage...
