Intercropping of Pea and Kheshari as Vegetables and Fodder Crop with Dwarf Type Sunflower Variety

To find out the optimum row arrangement of pea and khesari as intercrop with sunflower for higher productivity and return, a field experiment of intercropping pea and khesari with sunflower was conducted in Oilseed Research Centre, BARI, Gazipur during rabi season of 2020-21 and 2021-22. Six treatments were T1= Sole sunflower, T2 = One row of gardenpea in between two normal rows of sunflower (50 cm x 25 cm), T3 = Two rows of gardenpea in between two normal rows of sunflower, T4 = One row of kheshari in between two normal rows of sunflower (50cm x 25cm), T5 = Two rows of kheshari in between two normal rows of sunflower & T6= Broadcast kheshari in between two normal rows of sunflower. Although intercropping reduced sunflower yield but total productivity was increased due to addition of pea and khesari yield. Total productivity in terms of sunflower equivalent yield (SEY) (7.02 t ha-1 and 6.64 t ha-1 during 2020-21 and 2021-22 respectively) was found to be highest from T3 (two rows of pea in between two normal rows of sunflower treatment while the lowest (1.80 t ha-1 and 1.72 t ha-1) in T1 (sole sunflower) for both the years. Highest benefit cost ratio (BCR) (4.0 and 3.80 in 1st and 2nd year respectively) was recorded in T2 treatment (one row of gardenpea in between two normal rows of sunflower) with highest gross margin (Tk. 263905 ha-1 and Tk. 244012 ha-1).

Eight sunflower inbred lines were crossed in 8×8 diallel fashion (without reciprocal) and 28 F1 were developed at Oilseed Research Centre (ORC), Bangladesh Agricultural Research Institute (BARI), Gazipur in Rabi season, 2018. All F1 and their parents were planted in Rabi season 2019 to estimate general combining ability (GCA) and specific combining ability (SCA) effects for yield and yield attributes. The highly significant mean squares for genotypes for all the studied characters indicating wide variability in the parental materials. The highly significant GCA effects for stem diameter, days to maturity, number of seeds/head, 1000-seed weight and SCA effects for days to 50 flowering, days to maturity, head diameter, number of seeds/head, 1000-seed weight and seed yield were observed. The greater ratio of GCA/SCA implies the predominance of additive gene effect for all the studied characters. The parents, P1, P2, P3, P6 and P8 were found as good general combining parents for short duration, early maturity, lodging resistant, and 1000 seed weight. Crosses with the best SCA effects for some characters were found from the interaction of low × low, high × low, low × high or high × average combining parents. Further investigation on superiority and stability of good combining parents and hybrids over different years and locations is needed. Key words: Sunflower, Griffing’ method, general combining ability (GCA), specific combining ability (SCA).

Effect of different dosage of EMS on germination, survivability and morpho-physiological characteristics of sunflower seedling

Abstract To find out the effect of EMS dosage on sunflower variety BARI Surjamukhi-2, different EMS concentrations were compared at the molecular biology laboratory (MBL), Oilseed Research Centre (ORC), Bangladesh Agricultural Research Institute (BARI), Gazipur. A total of 10 seeds were treated with each treatment and % germination, % survival and early seedling growth was investigated. Decreased % germination was found with the increasing dose of EMS for all the treatment compared to the control, except for T 4 (0.6% EMS) treatment where a 100% seed was found to be germinated. With an exception of treatment T 4, a decreasing trend of % survivability with the increasing dose of EMS was observed. The gradual reduction with the increasing dose of EMS were observed for most of the studied characters such as leaf area, number of internodes, internode length, fresh and dry weight of leaf, dry weight of shoot, and fresh and dry weight of root in comparison to non-treated control seedlings. However, stimulatory effect with lower dosage of EMS was observed for shoot length in T 2 (0.2% EMS), root length in T 3 (0.4% EMS), and stem fresh weight in T 2 over control. Based on a quadratic regression analysis, using % survivability data, LD50 was calculated and optimum EMS dose was found 0.5%. Hence, the optimized EMS dose of 0.5% may be used to develop large scale desirable mutant of sunflower variety BARI Surjamukhi-2.

Comparative Effectiveness Of Neem Extracts And Synthetic Organic Insecticide Against Mustard Aphid

Effectiveness of different doses of neem extracts and a synthetic organic insecticide against mustard aphid was studied in the experimental farm of the Oilseed Research Centre, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur, during two consecutive years 2010-2011 and 2011-2012 for the control of mustard aphid. Eight treatments were evaluated against mustard aphid under field condition. The maximum aphid population was (180 per plant) observed at the pod formation stage of mustard crop. Among the treatments, Malataf (Malathion 57EC) @ 2ml/l significantly reduced the highest aphid population (93.75%) over pretreatment which produced the highest seed yield (1440 kg/ha) of mustard. The neem leaf extracts reduced 63.16-72.55% aphid population in mustard while neem seed extract reduced 73-81% aphid population over pretreated plants in both the years. Among the different doses of neem extracts, the highest aphid population reduction over pretreatment (81%) was recorded from 50g neem seed per litre of water treated plots with high MBCR (3.88) followed by 75g neem seed/l treated plots having reduction of 80% and MBCR 3.78.

Annual and growing season (1 May to 30 September) extreme daily values of maximum temperature, minimum temperature and precipitation were estimated from these scenarios on fine grids (0.5° latitude × 0.5° longitude) and from direct daily global climate model (GCM) outputs on coarse grids (~2.8° latitude × 2.8° longitude for CGCM3, 2.5° latitude × 3.75° longitude for HadCM3, and ~1.865° latitude × 1.875° longitude for ECHAM5/MPI-OM and CSIRO-Mk3.5). Compared with the corresponding values from direct GCM outputs, the extremes from daily climate scenarios generated by the AAFC-WG provided more detail at the finer spatial scale. Although the spatial patterns of the changes in climate extremes were often similar, actual values of the extremes from localized scenarios may be more reliable than those from direct GCM outputs since climate extremes under the present climate were not often realistically reproduced by the GCMs studied here. It is understood that the actual values are important as they provide the basis for climate change impact studies and the development of adaptation strategies.

Identifying Essential Test Locations for Oat Breeding in Eastern Canada

The oat (Avena sativa L.) breeding program at the Eastern Cereal and Oilseed Research Centre of Agriculture & Agri‐Food Canada has the responsibility to breed new oat cultivars for producers in eastern Canada, which includes Ontario, Quebec, and the Atlantic provinces. A 3‐yr multilocation test was conducted to understand the genotype × location interaction patterns and the relationships among test locations in eastern Canada. A genotype + genotype × environment interaction biplot analysis of yield data revealed three distinct oat mega‐environments in eastern Canada: (i) northern Ontario, (ii) southern and eastern Ontario, and (iii) Quebec and Atlantic Canada. To breed for all mega‐environments, initial yield screening must be conducted at locations representing each of these mega‐environments. Based on the relationships among test locations, six essential test locations were identified: three in Ontario, two in Quebec, and one in Atlantic Canada. Testing at all six locations appeared to provide a good coverage of the whole oat‐growing area in eastern Canada. Based on these findings, a breeding and test strategy was developed. This includes conducting initial yield screening at three locations in Ontario, Quebec, and Atlantic Canada, followed by a formal yield test at all six essential test locations. Specifically adapted genotypes selected from this test will then be tested in the Registration Tests in their respectively adapted subregions.

Since climate change impact models may be more sensitive to changes in climate extremes than to changes in climate means, there is a need to know the capability of stochastic weather generating techniques in reproducing climate extremes. An evaluation of 2 stochastic weather generators, namely LARS-WG and AAFC-WG, is presented in this study, from the perspective of reproducing observed climate extremes. Extreme daily values (highest daily maximum temperature, lowest daily minimum temperature and maximum daily precipitation) were analysed on a monthly and annual basis, as well as for the growing season (1 May to 30 September), for 9 stations across Canada. The evaluation was based on statistical tests for basic statistical properties and return values derived from fitted generalised extreme value distributions. Results showed that the weather generators LARS-WG and AAFC-WG could reproduce statistical properties of the extreme values of daily precipitation satisfactorily, including 10, 20 and 50 yr return values. However, the performance of the weather generators in reproducing extreme daily values of temperatures was not as good as for precipitation, especially that of LARS-WG. The deficiency in reproducing extremely low temperatures was also more noticeable than extremely high temperatures for LARS-WG. The mismatches of return values were often caused by a more extreme value estimated from synthetic data than that derived from observations.

Registration of ‘CDC Mindon’ Barley

‘CDC Mindon’ (Reg. No. CV‐337, PI 651860; CN107350; Canadian Food Inspection Agency [CFIA] Reg. No. 6224, Canadian PBR Appl. No. 07‐5903) is a two‐row spring feed barley (Hordeum vulgare L.) developed at the Crop Development Centre (CDC), University of Saskatchewan, Saskatoon, SK, Canada, with collaboration by Agriculture and Agri‐Food Canada at the Brandon Research Centre, Brandon, MB, Canada, and the Eastern Cereal and Oilseed Research Centre, Ottawa, ON, Canada. CDC Mindon was tested in CDC yield trials as SB00106 in 2000–2003 and in the Western Canadian Cooperative Two‐Row Barley Registration trial as TR04378 during 2004 and 2005. CDC Mindon was registered for production in western Canada as it has demonstrated good agronomic performance combined with good kernel quality and, of greater significance, enhanced resistance to Fusarium head blight (incited by Fusarium graminearum Schwabe) with lower deoxynivalenol accumulation in combination with tolerance to spot blotch [incited by Cochliobolus sativus (Ito & Kuribayashi) Drechs. Ex Dastur]. CDC Mindon is also resistant to the barley smuts (incited by Ustilago spp.).
