Weed Infestation

An experiment was carried out at the Agronomy Field laboratory of Bangladesh Agricultural University, Mymensingh during the period from November 2015 to March 2016 to study the effect of cultivar and seed rate on weed infestation and crop performance of wheat. Three wheat cultivars viz. BARI Gom 22, BARI Gom 23 and BARI Gom 24 and four seed rates viz. 80, 100, 120 and 140 kg ha-1 were taken as the experimental treatment. The experiment was carried out in randomized complete block design (RCBD) with three replications. The cultivar and seed rate significantly influenced weed infestation and crop performance of wheat. The dry weight of weeds under cultivar BARI Gom 24 was the lowest (4.18 g m-2) compared to other cultivars. The lowest dry weight of weed was recorded in the seed rate of 120 kg ha-1 (3.67 g m-2) and the highest one (6.69 g m-2) was produced under the seed rate of 80 kg ha-1. The highest number of effective tillers plant-1 (4.05), total number of tillers plant-1 (4.53), number of grain spike-1 (19.85) and grain yield (1.56 g) were produced by BARI Gom 24. BARI Gom 24 produced the highest grain yield (1.56 t ha-1) which was as good as BARI Gom 22 (1.40 t ha-1). BARI Gom 24 produced the highest grain yield with 100 kg seed rate and also a good competitor against weeds. Seed rate was a reliable factor where increasing seed rate reduced the intensity of weed infestation and weed dry weight production. In conclusion, cultivation of BARI Gom 24 at the rate of 120 kg ha-1 seeds may be cultivated for higher grain yield. Res. Agric., Livest. Fish.8(1): 1-8, April 2021

An experiment was carried out at the Agronomy Field laboratory of Bangladesh Agricultural University, Mymensingh during the period from November 2014 to March 2015 to study the effect of cultivar and seed rate on weed infestation and crop performance of wheat. Three wheat cultivars viz. BARI Gam 24, BARI Gam 25 and BARI Gam 26 and five seed rates viz. 80, 90, 100, 110 and 120 kg ha-1 were considered as the experimental treatment. The experiment was carried out in Randomized Complete Block Design with three replications. The cultivar and seed rate were significantly influenced on weed infestation and crop performance of wheat. The dry weight of weeds in cultivar BARI Gam 26 was the lowest (9.24 g m-2) compared to other cultivars. The lowest dry weight of weed was recorded in the seed rate of 120 kg ha-1 (7.57 g m-2) and the highest one (16.14 g m-2) was produced in seed rate of 80 kg ha-1. The highest plant height (93.27 cm), number of effective tillers plant-1 (3.69) and 1000-grain weight (44.51g) were produced in BARI Gam 25. The highest number of spikelet spike-1 (18.12) and grains spike-1 (34.51) were produced by BARI Gam 26. BARI Gam 26 produced the highest grain yield (2.51 t ha-1) which was as good as BARI Gam 25 (2.48 t ha-1). BARI Gam 26 produced the highest grain yield with 100 kg seed rate and also a good competitor against weeds. Seed rate was a reliable factor where increasing seed rate reduced the weed dry weight production. In conclusion, cultivation of BARI Gam 26 @100 kg ha-1 seeds may be cultivated for higher grain yield.Progressive Agriculture 27 (1): 20-26, 2016

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to December 2014 with a view to finding out the effect of variety and level of nitrogen on the yield performance of fine aromatic rice. The experiment consisted of three varieties viz. Kalizira, Binadhan-13 and BRRI dhan34, and six levels of nitrogen viz. 0, 30, 60, 90 kg N ha-1, USG 1.8 g 4 hills-1 (55 kg N ha-1) and USG 2.7 g 4 hills-1 (80 kg N ha-1). The experiment was laid out in a randomized complete block design with three replications. Variety, level of nitrogen and their interaction significantly influenced the yield of aromatic rice. The highest grain yield (3.33 t ha-1) was obtained from Binadhan-13 followed by BRRI dhan34 (3.16 t ha-1) and the lowest grain yield was found in Kalizira (2.11 t ha-1). In case of N, the tallest plant (140.3 cm), highest number of effective tillers hill-1 (11.40), grains panicle-1 (152.8), and grain yield (3.32 t ha-1) were obtained when fertilized with USG 1.8 g 4 hills-1 and the lowest values were found in 0 kg N ha-1. Therefore, Binadhan-13 fertilized with USG 1.8 g 4 hills-1 (55 kg N ha-1) appeared as the promising practice for appreciable grain yield.J. Environ. Sci. & Natural Resources, 9(1): 41-45 2016

Effect Of Age

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh during the period from July to October 2016 to study the effect of age of seedling on the yield and yield contributing characters of short duration Aman rice cultivars. The study consisted two factor A: Variety- three- i)    BINA dhan7 (V1),   (ii) BRRI dhan56 (V2) and (iii)  BRRI dhan62 (V3); and factor B: Number of seedlings hill-1- (i)   Single seedling  hill-1 (S1), (ii)  Two seedlings  hill-1 (S2) and (iii) Three seedlings  hill-1 (S3). The experiment was laid out in a randomized complete block design with three replications. The highest grain yield was obtained from the cultivar BINA dhan7 which was statistically identical with BRRI dhan56 and this was the consequences of higher number of total and effective tillers hiil-1 and highest number of grains panicle-1. Grain yield was not significantly affected by the number of seedlings hill-1 but numerically the highest grain yield was recorded from single seedling hill-1. From the interaction it is observed that grain yield was not significantly affected by the interaction of cultivar and number of seedlings hill-1. But numerically the highest grain yield was recorded from the interaction of BRRI dhan56 × single seedling hill-1. From the economic analysis it is observed that the highest BCR (1.64) was recorded from single seedling hill-1 in BRRI dhan56 which was close to single seedling hill-1 in BINA dhan7 and the lowest BCR (103) was obtained from two seedlings hill-1 in BRRI dhan62. From the results of the study it may be concluded that BRRI dhan56 with single seedling hill-1 might be cultivated in AEZ-9 for obtaining higher yield and higher economic return in Aman season.Progressive Agriculture 28 (4): 279-286, 2017

Yield And Yield Components

A field experiment was laid out in order to evaluation of effects water stress on yield and yield components of wheat cultivars in Lorestan province in Islamic Azad University, Boroujerd branch, Iran at 2014. The experiment was laid out in a split-plot design based on randomized block design with three replications. Treatments were irrigation in five levels such as 1: four period irrigation after anthesis, 2: three period irrigation after anthesis, 3: two period irrigation after anthesis, 4: one period irrigation after anthesis and 5: control in main plots and  three wheat cultivars (Shiraz, Pishtaz and Bahar) in sub plots.  The results showed that, the effect of water stress, cultivar and interaction between them on all parameters were significant at 1% level. The height of Pishtaz cultivar was taller than other cultivars. The Pishtaz cultivar with one period irrigation after anthesis had the highest number of spike per square and Bahar cultivar with one period irrigation after anthesis had the lowest number of spike per square. However, 1000- grainwas decreased in water deficit treatment.  However, the Pishtaz cultivar with four period irrigation had the highest plant dry weight and grain yield and Bahar cultivar non irrigation treatment after anthesis had the lowest plant dry weight and Shiraz cultivar in non-irrigation treatment had the lowest grain yield. The results showed that yield and yield components of common wheat decreased with increasing of water deficit and for increasing in grain yield of wheat complete irrigation are needed. However, Pishtaz cultivar had a highest grain yield and dry matter production. Then we can increase grain yield and production of wheat with cultivation of Pishtaz cultivar and avoid of water stress.DOI: http://dx.doi.org/10.3126/ijls.v9i5.12707

The present study was carried out to determine the contribution of main stems and tillers to the total yield of two wheat cultivars (Triticum aestivum L.), Cocoraque and BH-1146, under two water treatments: a) normal field conditions, and; b) irrigation, in Londrina, PR, Brazil. The experiment was an eight replication randomized complete block design with treatments arranged in split-plots. Data on total grain yield, main stem grain yield, tillers grain yield, the ratio between tiller and total grain yield, yield components and other 17 traits were collected. The cultivar BH-1146 had a higher total grain yield in relation to Cocoraque under normal field conditions; i, e., under water stress. Main stem grain yield responded positively and significantly to irrigation which was the main cause of increased yield in both cultivars. The tiller grain yield contributed little to the total yield.

An experiment was carried out in the Entomology Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh to determine the efficacy of six botanicals and four chemical insecticides for controlling rice hispa, Dicladispa armigera during the period of July to December 2013. In conducting the experiment BR11 rice variety was selected where ten treatments namely six botanicals such as Neem oil, Mahogany oil, Mixture of Neem and Mahogany oil, Bishkatali leaf extract, Pitraj leaf extract and Mixture of Bishkatali and Pitraj leaf extract and four chemical insecticides Sevin85SP, Advantage20EC, Cup50EC, Kinalux 25EC  were laid out in the Randomized Complete Block Design (RCBD). Overall leaf infestation by rice hispa and infestation by adults and grubs separately were recorded at different time intervals. In addition to these, overall effect of pest infestation on the grain yield of rice was also examined. Among the six botanicals, Neem oil was most effective in controlling rice hispa, as overall leaf infestation was 21.20% and the infestation by adults and grubs were 14.43% and12.57%. On the other hand, among chemical insecticides, maximum efficacy was found under the treatment of Sevin 85SP where minimum leaf infestation was 9.22%, infestation by adults and grubs were 5.88% and 5.00% respectively. In case of yield, Sevin 85SP (4.62 ton/ha) showed the best efficacy in comparison to other treatments. Therefore, application of Sevin 85SP (3.46ml/L) and Neem oil (2ml/100ml) were examined as the best options in controlling rice hispa. So, it could be recommended to use Sevin 85 SP and Neem oil for the management of rice hispa.Progressive Agriculture 28 (2): 64-72, 2017

Pot experiment was conducted in a randomized complete block design with three replication and six treatments in the screenhouse of Soil Science Division, Khumaltar during the year 2003 and 2004. The objective of the experiment was to find out the effect of vermicompost in combination with or without soil and mineral fertilizers on the yield and other attributes of chickpea. The results showed an encouraging effect of vermicompost application on the plant height, root length and biomass dry weight of chickpea when vermicompost was applied in equal ratio with soil (5 kg each/pot) and 10:20:15 kg N: P2O5:K2O kg ha-1. Vermicompost with equal ratio of soil (5 kg each/pot) also produced the highest mean grain yield of 10.6 gm per pot. However, no significant treatments effects were observed for root length and straw weights of the chickpea.Nepal Agric. Res. J. Vol. 9, 2009, pp. 49-55DOI: http://dx.doi.org/10.3126/narj.v9i0.11641

Nitrogen Rates

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to examine the effect of number of seedlings hill‑1 and rate and time of nitrogen application on the yield of late transplant Aman rice (cv. BR23). The experiment comprised three levels of number of seedlings hill-1 viz. 2, 4, and 6, three nitrogen rates viz. 0, 60 and 120 kg N ha-1 and three levels of time of nitrogen application viz. nitrogen application in two equal splits at 15 DAT and early tillering stage (ET); nitrogen application in three equal splits at 15 DAT, ET and panicle initiation (PI) stage; nitrogen application in four equal splits at 15 DAT, ET, PI and flowering (F) stages. The experiment was laid out in a randomized complete block design with three replications. Number of effective tillers hill‑1, grain yield and straw yield were the highest when 6 seedlings were transplanted hill‑1 while all yield contributing characters, grain and straw yields were the highest at 120 kg N ha-1. In case of interaction, the highest grain yield was recorded in combination of 6 seedlings hill-1 × 120 kg N ha-1 and 120 kg N ha-1 × three times of nitrogen applications (15 DAT + ET + PI). The highest number of effective tillers hill-1 and grain yield were recorded in 6 seedlings hill-1 × 120 kg N ha-1 × three times N application (15 DAT + ET + PI) and thus this practice appears as the promising one for late transplant Aman rice ( cv. BR23) cultivation.Int J Appl Sci Biotechnol, Vol 3(4): 692-698
