Comparative yield performance study of some mustard mutants at Rangpur region of Bangladesh

ABSTRACT

The present research was conducted at the farmer’s field of Rangpur during Rabi season 2018-19 to investigate the growth and yield performance of mustard mutants. The experiment was arranged in a randomized complete block design consisting of two mustard mutants (viz. MM-35, MM-36, MM-37 and BINA Sarisha-7) as treatment and replicated thrice. All the growth, yield attributes and yield were substantially influence among the mustard mutants except the phenological parameters. Results of the experiment showed that the highest plant height in BINA Sarisha-7 (142.87 cm) and MM-36 was found better in respect of maximum seed yield (1.75 ton/ ha), number of branches (3.87), 1000-seed weight       (3.11 g). Besides this, MM-37 showed the maximum number of seeds siliqua-1. Therefore, findings of this study suggested that MM-36 would be suitable for better productivity and recommended for cultivation at Rangpur region in Bangladesh.

Vegetative performances of BARI hybrid maize-7 as influenced by nitrogen doses and irrigation frequencies

ABSTRACT

A field study was conducted to assess the interaction effects of irrigation and nitrogen rates on hybrid maize yield. The research was conducted during December 2013 to April 2014 at the farmer field Tabaria area of Natore District in Bangladesh. The experiment consists of (i) two irrigation treatments viz. no irrigation and three irrigation and (ii) two nitrogen levels viz. no nitrogen use and 230 kg Nha-1.The experiment was laid out in a split plot design with three replications having 12 unit plots with 20 m2 sized. The interaction effect of irrigations and nitrogen levels significantly influenced the studied vegetative performances of BARI hybrid maize-7, where the growth attributes increased with increasing irrigation and nitrogen levels in all cases.

Introduction The crop maize is gaining popularity in the country very quickly due to its high yield potential. Maize acreage and production have an increasing tendency with the introduction of hybrid since 1993 (Karim      et al., 2010). The population growth in Bangladesh puts great pressure on the country’s food production. As regard food, cereal is still staple one for Bangladeshi people. In terms of human consumption maize also occupies the third position after rice and wheat in the country (HIES, 2005).The country is importing a huge amount of maize with the increasing demand from poultry and other feed industries. Therefore, maize has gained an increasingly important attention by the government. Now days, there are many organizations who are working for increasing maize production in Bangladesh. Maize production increased significantly during the last decade and still there is a large demand-supply gap. Local production cannot meet the demand and hence imports fill that gap. The growth of maize production did not spread all over the country though there are potential and still now is mainly concentrated in the north and north-western part of Bangladesh. However, Maize has high yield potential and responds well to different management practices. Among various management practices, irrigation and nitrogen play a significant role in realizing the maximum potential of the crop. Irrigation scheduling is the technology for applying the proper amount of water at the right time. Reasons for using irrigation scheduling are to reduce water applications, energy consumption and deep percolation of water below the crop root zone. Water is further required to provide constant turgor pressure that supports the plant and facilitates cell enlargement after cell division has been initiated. Hence, plant growth and survival depend on adequate water availability. Hence, the present study was therefore, undertaken to determine the optimum level of irrigation schedules and nitrogen rates for enhanced growth of maize in Bangladesh.

Effect of sowing method on jute seed yield at Kishoreganj and Patuakhali districts of Bangladesh

ABSTRACT

An experiment was conducted two consecutive locations at Jute Research Regional Station (JRRS), Kishoreganj and Jute Research Sub Station (JRSS), Patuakhali to find out the seed yield at different sowing methods. Three popular varieties e.g., BJRI Tossa Pat-8 (Robi-1), O-9897, JRO-524 and three sowing methods e.g., direct seeding, top cutting and seedling transplanting and methods were used as experimental treatments. The experiment was carried out RCBD with three replications. Results revealed that the highest seed yield was produced (690, 681Kg ha-1) in Robi-1 and (667, 697 Kg ha-1) from direct seeding method in both Kishoreganj and Patuakhali, respectively.

Potassium determination in seven distinguish soils of different AEZ and its impacts on rice yield

ABSTRACT

An incubation study was continued in the net house of the Department of Soil Science, Bangladesh Agricultural University, Mymensingh during Boro season (31 December 2013 to 10 March 2014) to judge the distribution of native and added K in soils and its effect on rice. Seven soil samples viz: BAF (Brahmaputra Alluvial Flooded), BANF (Brahmaputra Alluvial Non-flooded), LBT (Level Barind Tract), GTF (Ganges Tidal Floodplain), OHPP (Old Himalayan Piedmont Plain), NEBT (North Eastern Barind Tract) and MT (Madhupur Tract) were collected from six different AEZs of Bangladesh. In this study, the water soluble, exchangeable and non-exchangeable K of the different soils ranged from 2.30 to 23.40, 27.30 to 163.80 and 234.0 to 877.50 mg kg-1, respectively in non-treated samples. The addition of 100 mg K per kg soil increased the different forms of K. The percent increase here 12.30 to 73.33 for water soluble K, 6.42 to 78.75 for exchangeable K and 6.9 to 35.0 for non-exchangeable K over the initial status. The dry matter yield of different non-treated and treated pots ranged from 2.08 to 4.4 and 3.77 to 5.48 g pot-1. The highest dry matter yield was found in LBT soil for non-treated pots and the lowest in BAF. In case of treated soil, the highest dry matter yield found in OHPP and the lowest in GTF soil.

Effect of seed rate and nitrogen doses on yield performances of lentil

ABSTRACT

An experiment was conducted at the agronomy field of Bangladesh Agricultural University, Mymensingh to determine the effect of seed rate and fertilizer doses on yield components of lentil (Lens culinaris Medic). The experiment was laid out in randomly complete block design (RCBD) with three replications. Three doses of nitrogen fertilizer, viz. N1= 25 kg/ha, N2= 40 kg/ha, N3= 55 kg/ha and two seed rate, viz., S1= 35 kg/ha, S2= 45 kg/ha were used as experimental treatments. Result revealed that the highest yield (1.067 tha-1) was found in higher seed rate (S2-45 kgha-1). On the other hand, medium fertilizer dose (40 kgha-1 urea dose) confirmed the highest yield (1.1083 tha-1) of lentil. Furthermore, the highest lentil yield (1.20 tha-1) was recorded in S2N2 interaction. The study also concluded that yield was positively correlate with plant height, number of branches per plant and number of pods per plant but negatively correlate with days to maturity.

Introduction Lentil (Lens culinaris) is an important food source for the people especially in the subcontinent (Singh and Singh, 2014). It is originated mainly from the eastern Mediterranean Egypt, Greek & Asia then Hindukush Mountain in India and later stage in Africa, America & Europe (Al-Khayri et al., 2019).  It is rich in proteins and contains high concentrations of essential amino acids like isoleucine and lysine, as well as other nutrients like dietary fiber, folate, vitamin B1, and minerals (Rozan et al., 2001). Research showed that it contains 25% protein, 60% CHO, 4.5% fat and 11% water which are comparatively higher than the other pulse crops (Singh et al., 2016). It is grown as a sole crop and may be inter-cropped with wheat, mustard and chickpea (Biswas et al., 2020). Although lentil requires fertilizers however, it also plays important role to fix nitrogen to soil from the atmosphere (Suryapani et al., 2012). Bangladesh is an over populated country and cultivable land is decreasing day by day creating major problems for food. To get higher production from the available cultivable land resources, feasible conditions for cultivation are needed and the importance of nutrients in plant growth and yield are well known (Shrivastav et al., 2020). Nitrogen is one of the essential plant nutrients, which can augment the production to a great extent. Again, seed rate has a positive effect on total yield as well as with the net profit return (Boyer et al., 2020). Reports showed that combination of seed rate with fertilizer can increase the yield as well as protein content of barley and wheat seed (Walsh and Walsh, 2019). So, this experiment was undertaken to understand the combine effect of seed rate and nitrogen doses on the growth and yield of lentil.
