An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from November 2010 to May 2011 to study the effect of variety and rate of nitrogen on the performance of Boro rice. The experiment comprised three varieties viz., BRRI dhan28 (V1), BRRI dhan29 (V2) and BRRI dhan45 (V3); and five rates of nitrogen viz., control (N0), 50 kg  (N1), 100 kg (N2), 150 kg  (N3)and 200 kg  (N4) N ha-1. The experiment was laid out in a randomized complete block design with four replications. The growth analysis results indicate that the tallest plant (80.88 cm) and the highest number of total tillers hill-1 (13.80) were observed in BRRI dhan29 at 70 DATs and the highest total dry matter (66.41 g m-2) was observed in BRRI dhan45. The shortest plant (78.15 cm) and the lowest number of tillers hill-1 (12.41) were recorded from BRRI dhan45 and the lowest dry matter (61.24 g) was observed in BRRI dhan29. The tallest plants (84.01 cm), highest number of tillers hill-1 (14.06) and the highest dry matter (69.58 g m-2) were obtained from 200 kg N ha-1. The tallest plants (86.48 cm) and maximum dry matter (72.30 g m-2) were recorded from BRRI dhan28 with 200 kg N ha-1 and BRRI dhan45 with 200 kg N ha-1, respectively. The highest number of tillers hill-1 (15.14) was obtained from BRRI dhan29 with 50 kg N ha-1. The harvest data reveal that variety had significant effect on total tillers hill-1, effective tillers hill-1, non-effective tillers hill-1, panicle length, grain yield, straw yield and harvest index. The highest grain yield (4.84 t ha-1) was recorded from BRRI dhan29. The results of the experiment also indicate that total tillers hill-1, effective tillers hill-1, grains panicle-1, sterile spikelets panicle-1, grain yield, straw yield and harvest index were significantly affected by levels of nitrogen, while plant height, panicle length, 1000-grain weight were not significantly affected by levels of nitrogen. The highest grain yield (5.58 t ha-1) was obtained from 200 kg N ha-1. Interaction effect of variety × 200 kg N ha-1 produced the highest grain yield (5.82 t ha-1). From the results of the study it may be concluded that BRRI dhan29 rice may be cultivated with 200 kg N ha-1 for obtaining higher yield in AEZ 9 of Bangladesh.Progressive Agriculture 26:6-14, 2015

The experiment was conducted at the Agriculture Field laboratory of Noakhali Science and Technology University, Noakhali, Bangladesh during the period from December 2020 to February 2021 to observe the effect of different levels of nitrogen (N) and phosphorus (P) fertilizer on growth and yield of lettuce. The experiment comprised of two factors. Two inorganic fertilizers like different level of nitrogen and phosphorus viz; nitrogen-control 0 kgha-1 (N0), 100 kgha-1 (Nı), 150 kgha-1 (N2) and 200 kgha-1 (N3) and phosphorus-control 0 kgha-1 (P0), 50 kgha-1 (P1), 62.5 kgha-1 (P2) and 75 kgha-1 (P3). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Application of different levels of nitrogen and phosphorus significantly influenced the plant height, leaves number plant-1, leaf area, fresh leaf yield plant-1, gross yield, and dry matter content of lettuce. The maximum plant height, leaves number plant-1, leaf area, fresh leaf yield plant-1, gross yield and dry matter content were obtained with the application of 200 kg N ha-1. On the other hand, with the application of 75 kg P ha-1 the maximum plant height, leaves number plant-1, leaf area, fresh leaf yield plant-1, gross yield and dry matter content were found. In case of different treatment interaction, N3P3 (200 kg N ha-1 + 75 kg P ha-1) produced the highest gross yield (32.2 tha-1) and the lowest gross yield (16.11 tha-1) found from control treatment.

Maize is one of the promising crops for foods, green forage and industrial uses. There is lot of research about maize regarding various aspects in Bangladesh. However, no published review report on the present status, problems and prospects of maize production in Bangladesh has been found. In this review, we provided intensive information to increase maize production and profitability in Bangladesh from all the available resources i.e., journal article, book, proceeding and electronic sources. This paper showed that maize cultivation was more profitable in Bangladesh and indicated some problems with maize cultivation as well as suggested some recommendations to improve maize production. Understanding all the facts about this paper will boost to maize production in Bangladesh and assist to researchers to choose advance topics about the improvement of maize cultivation.

The experiment was carried out to investigate the effect of rhizobium inoculum and phosphorus fertilization on nodulation, growth, and yield of soyabean cv. Binasoybean-2 at the area of Chamberkella, East Subarnachar Upazila, Noakhali, Bangladesh, from mid-January to first week of May 2018. Four levels of Rhizobium inoculation viz: 0, 25, 50 and 75 g kg-1 and four levels of phosphorus viz: 0, 18, 36 and 54 kg P ha-1 were applied. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The effect of interaction of different combinations of Rhizobium inoculation and phosphorus rates showed regular trend, although their effects on some of studied growth, and yield parameters were insignificant but most of the growth and yield parameters were significant. Among sixteen treatment combinations the highest grain yield (2.217 t ha-1) was obtained from the treatment combination of 50 g kg-1 Rhizobium inoculation and 36 kg ha-1 phosphorus which was statistically identical with 50 g kg-1 Rhizobium inoculation with 18 kg ha-1, the lowest yield (1.367 t ha-1) was recorded with control treatment.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University to observe the effect of sowing methods and weeding regimes on the yield of sesame. The experiment comprised of two factors. Two methods of sowing i.e., broadcasting and line sowing (S2), and six weeding regimes- control (T0), weed free (T1), one hand weeding at 15 DAS (T2), two hand weedings at 15 and 30 DAS (T3), three hand weedings at 15, 30 and 45 DAS (T4) and application of Panida (Pendimethalin) herbicide (T5) at 3 DAS. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Almost all the yield characters of sesame were affected significantly due to sowing methods, weeding regime and their interaction. Result showed that the l ine sowing showed better performance regarding plant height (100.40 cm), number of branches (4.983) plant–1, number of capsules plant–1 (47.82), number of seeds capsule–1 (69.66), 1000–seed weight (2.96 g), seed yield (956.90 kg ha–1), stover yield (2167.0 kg ha–1), biological yield (3123.00 kg ha–1) and harvest index (31.45%) than that of broadcasting method. Also weed free treatment had the highest plant height (101.90 cm), highest number of branches (5.00) plant-1, highest capsule (47.08) plant–1, heaviest 1000–seed weight (3.28 g), highest number of seeds capsule–1 (76.22), highest seed yield (974.30 kg ha–1), stover yield (2947.0 kg ha–1) and biological yield (3922.0 kg ha–1) as compared to other treatments while unweeded plot had least significant effect among the whole yield and yield attributes of sesame. In case of interactions, both weed free treatment and herbicidal effect with line sowing methods produced the highest plant height, number of branches and capsules plant–1, seeds capsule–1, seed yield, stover yield and biological yield (109.80 cm, 5.967, 56.57, 81.53, 1054.0 kg ha–1, 3139.0 kg ha–1 and 4193.0 kg ha–1, respectively) as compared to other interaction combinations. The results of the study reveal that the weed free treatment along with line sowing would be the proper technique for higher production of sesame. But line sowing along with application of Panida herbicide would be the best combination for obtaining higher yield of sesame since it is not feasible for the farmers to keep their field weed free throughout all the growing periods.
