“…The highest grain yield (3.54 t ha -1 ) was recorded in 20 cm × 10 cm spacing due to the highest number of effective tillers hill -1 and highest number of grains panicle -1 . This finding corroborates the findings of Saha et al (2020) who obtained the highest grain yield in 20 cm × 10 cm spacing in boro rice. Plant spacing also exerted significant effect on straw yield.…”

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from April to August 2019 to find out the effect of spacing of transplanting and nitrogen level on weed growth and yield performance of aus rice (cv. Binadhan-19). Four spacings of transplanting (25 cm × 15 cm, 25 cm × 10 cm, 20 cm × 15 cm and 20 cm × 10 cm) and four levels of nitrogen (control, 50% of RD, 100% of RD, 150% of RD and application of USG) were used in this experiment. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Nine weed species belonging to five families infested the experimental field. Among the nine species three were grasses, three were broad leaves and three were sedges. Paspalum scrobiculatum, Echinochloa crusgalli, Digitaria sanguinalis, Oxalis europaea, Monochoria vaginalis, Nymphaea nouchali, Cyperus difformis, Scirpus juncoides and Fimbristylis miliacea were the important weeds in the experimental plots. The highest weed density at 20 DAT (14.43) and 40 DAT (17.40) were obtained from spacing of 20 cm × 15 cm and 20 cm × 10 cm, respectively. Control treatment showed maximum weed densities (15.08 and 18.41, respectively) at both sampling dates. The highest weed density (16.67) was recorded from the treatment combination of 20 cm × 10 cm spacing with control treatment at 20 DAT and the highest weed density (19.66) was recorded from treatment combination of 20 cm × 10 cm spacing with 150% of RD of nitrogen at 40 DAT. Spacing of 20 cm × 10 cm gave the highest (3.54 t ha-1 ) grain yield compared to other spacings. The highest number of grains panicle-1 was found in 20 cm × 10 cm spacing compared to other spacings used in the study. The highest grain yield (3.89 t ha-1 ) was recorded from application of USG, which was significantly higher than other nitrogen levels. The 20 cm × 10 cm spacing produced the highest grain yield (4.41 t ha-1 ) with application of USG, whereas 20 cm × 15 cm with no nitrogen (control) treatment produced the lowest grain yield (2.39 t ha-1 ). So, it can be concluded that 20 cm × 10 cm spacing of transplanting with application of USG may be used for maximization of yield of Binadhan-19 in aus season.

“…The inherent features of the yield contributing characters of a crop play an important role towards the yield accumulation. Genotypes are considered as an innate factor having a lot of contributions to the production of the yield components and yield of a crop as a result of the interactions with the growing environment ( (Dass et al, 2017) which has a role in governing all of the components of plants needed for growth and yield (Saha et al, 2020). The optimum plant spacing helps both the aerial and underground parts of a plant to utilize the solar radiation and nutrient elements for ensuring the proper growth and development (Rahman et al, 2007;Bhowmik et al, 2012;Paul et al, 2017).…”

Plant spacing ensures uniform and optimum plant population and facilitates sufficient natural resources for crop growth which, in turns influences the crop yield positively. An investigation was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, during July to December 2017 to study the influence of plant spacing on the yield of double grained rice cultivar. The study comprised five spacing viz. 25 cm × 15 cm, 25 cm × 10 cm, 20 cm × 15 cm, 20 cm × 10 cm and 15 cm × 15 cm and two rice cultivars viz. a double grained rice cultivar and BRRI dhan49 and a double grained rice cultivar. It was laid out in a randomized complete block design with three replications. The double grained rice cultivar produced taller plant (155.65 cm), longer panicle (23.93 cm), higher 1000-grain weight (25.96) and higher straw yield (6.90 t ha-1), though the higher grain yield (3.68 t ha-1) was found in the test cultivar (BRRI dhan49). Planting at 20 cm × 15 cm produced the highest grain yield (3.70 t ha-1) which was at par with 25 cm × 15 cm, 25 cm × 10 cm and 20 cm × 10 cm while planting at 15 cm × 15 cm produced the lowest grain yield (3.13 t ha-1). The interaction of the double grained rice cultivar with all spacing combinations produced taller plants than the spacing combinations with BRRI dhan49. The higher grain yield (3.52 t ha-1) was found in the double grained rice cultivar with 20 cm × 10 cm spacing which was at par with the spacing of 20 cm × 15 cm and 25 cm × 15 cm, respectively; although BRRI dhan49 always produced the higher yield. The lowest grain yield (3.08 t ha-1) was recorded at the double grained rice cultivar with 25 cm × 10 cm spacing, however, the same treatment produced the highest biological yield (11.23 t ha-1) due to the highest straw yield (8.15 t ha-1). Hence, the spacing 20 cm × 15 cm might be recommended for the higher grain yield in the double grained rice cultivar Res. Agric., Livest. Fish.8(3): 273-279, December 2021
