Yield trial of BINA released sesame varieties at Kishoreganj district of Bangladesh

An experiment was done during the period of Kharif-I (Summer) season 2023 at Pakundia upazilla of Kishoreganj district in Bangladesh to explore the yield performances of sesame varieties developed by Bangladesh Institute of Nuclear Agriculture (BINA). Three replications of a Randomized Complete Block Design (RCBD) were used, where Binatil-1, Binatil-2, Binatil-3 were the different variations. The experiment’s findings showed that the genotypes significantly differed in terms of days to maturity, plant height, number of developed branches, number of pods, length of pods, pod breadth, seeds contain per pod, weight of 1000 seeds and yield of seeds. Binatil-1 contained the tallest plant (106.00 cm), whereas Binatil-3 was the shortest plant (78.50 cm). It was noted that Binatil-2 had the greatest number of plant-1 branches (5.05), whereas Binatil-1 had the least amount (2.20). Additionally, Binatil-3 displayed the highest number of plant-1 pods (96.76) whereas Binatil-1 provided the lowest amount (50.72). Binatil-1 had the largest pod  (3.62 cm), whereas Binatil-3 had the smallest (2.63 cm) size. It was noted that Binatil-1 displayed the greatest number of seeds in pod-1 (78.35). The highest 1000-seed weight was recorded in Binatil-2 (3.18 g), whereas the lowest weight was in Binatil-1 (2.92 g). The variety Binatil-2 had the highest seed yield (1.38 ha-1), whereas Binatil-1 had the lowest (1.25 ha-1). Among the cultivars, Binatil-3 matured in the fewest days (88), whereas Binatil-2 required the most days (96). Overall, Binatil-2 gave the significant growth and yield performance in Kharif-I (summer) season trial. Furthermore, it will be useful for Bangladesh to choose sesame genotypes with high yield potential and future breeding stock.

Optimizing zinc and boron requirements for the T. aman -boro rice cropping pattern

The intensification of agricultural land use, along with the cultivation of modern crop varieties, has witnessed a significant upswing in Bangladesh. Unfortunately, this surge has taken a toll on soil fertility, leading to the emergence of deficiencies in both macro- and micro-nutrients for crops. In light of these concerns, a study was conducted to assess the impact of applying zinc (Zn) and boron (B) on the yield of T. Aman and boro rice while determining the optimal Zn and B application rates for the T. Aman – boro cropping pattern in AEZ 9. Soil samples from the experimental site were collected and subjected to analysis for fundamental soil properties, including pH and organic matter content, macronutrients such as nitrogen (N), phosphorus (P), potassium (K), and sulfur (S), as well as micronutrients like Zn and B. All analyses were conducted in accordance with established standard methods. For T. Aman, there were four treatments, denoted as (T1:  Zn0B0, T2:  Zn2B1.5, T3:  Zn4B2, andT4:  Zn6B3), while six treatments were applied to Boro rice, named T1.1 (Zn0B0), T2.1 (Zn2B2), T2.2 (Zn0B0), 3.1 (Zn4B2), T3.2 (Zn0B0) and T4.1 (Zn0B0), with subscripts indicating the application rate in kg per hectare. Each treatment was replicated three times, and consistent rates of nitrogen, phosphorus, potassium, and sulfur were applied to all plots. Zn and B treatments were imposed during both the first and second crop cycles, as indicated above, with Zn being supplied as ZnSO4 and B as H3BO3. The results indicate that applying Zn @4 kg ha-1 and B @ 2 kg ha-1 to the first crop, or Zn@2 kg ha-1 and B      @2 kg kg ha-1 for both the first and second rice crops, can yield the highest grain production in the rice-rice cropping pattern.

Study and research conducted in the world happiest country-Finland including observations and evaluations on social cultural political agricultural technological natural and environmental situations for 9-years (1976-84) as first Bangladesh people

Introduction

After Iceland, Finland is the northen most country in the world, where one-third of total length lies on the north of Artic circle. The country’s northern most point is Utsjoki (70°5¢ 30² N), southern most point is Tulliniemi (58°48¢ 30² N), westernmost point is Koltapahtaniemi, Lapland (20°33¢ 27²E) and easternmost point Virmajarvi of Ilomantsi (31°35¢ 20² E). Finland’s frontier is 3,600km, land 2,571 km, 586 km land boundary with Sweden, 716 km with Norway and 1,269 km with Russia. The highest length covers 1,160 km and width 540 km, with surface area 3,37,032 sqkm, where land coverage 305,475 sqkm and water body 31,557 sqkm. The land area is formed during and after the final stage of last Ice age mostly due to movement of icesheets. Then part of the surface bed rocks turned into soils due to weathering and disintegration processes. Finland is known as low lying fairly flat country, break down of bed rocks for thousands of years with altitude 152m above sea level. Altitudes devides Finland into two-lowlands and uplands. Land is the highest point (1,328m) i.e. Haltiatunturi. One third Finland has 9.4% inland water i.e. 31.55 sqkm. There are 55-75 thousand lakes in Finland with mean depth of 7m covering 3,00,000 km lake shore. The largest lake Saima that is 35th largest in the world (4,400 sqkm) and 5th largest in Europe. Here coastline covers 20,000. There are rather few rocky islands along with west coast. Finland territorial limit runs 4 nautical miles from the coast Finland lies in the snow and forest zone characterized by cold damp winters and warm summers. The summer temp. varies from 13°-17°C with maximum of 30°C, average rainfall 700mm (southwest) and 400mm in the northwern zone (Lapland) where 30-40% rainfall comes as snow. Snow cover starts in Oct/Nov. and continues to mid-summer/April. In Lapland snow covers continues until June each year. The snow last for 70-100 days in south west Finland, 160-190 days in eastern zone and then 200-210 days in the north (Lapland). The water ways freezes in Oct-Nov. in northern side sea in December and continues until May-June (Lapland). The longest day in the south in hrs. and shortest 6 hrs. but in Lapland enjoys nightless night in summer (70°N), sun never sets for 73 days but in winter it never rises for 51 days.

In 1978 there were 4,513 thousand or 4.5 million people in Finland and in 2000 total population was 4.747 million; and recently in 2023 it was observed/estimated to 5.5 million people in Finland. There are more than 90 large to small cities in Finland. Here 14 cities with approximate thousand, population (in brackets) in 1980s are listed here: (1) Helsinki (488), (2) Tampere (166), (3) Turku (165), (4) Espoo (126), (5) Vantaa (125), (6) Lahti (95), (7) Oulu (93), (8) Pori (80), (9) Kuopio (73), (10) Jyvaskyla (63), (11) Kotka (62), (12) Vaasa (54), (13) Lapperanta (54), (14) Joensuu (44).

Study on yield potential of some promising sesame genotypes at Pabna district of Bangladesh

ABSTRACT

An experiment was done during the period of Kharif-I (summer) season 2023 at Pabna district in Bangladesh to explore the yield and factors affecting yield of two sesame varieties developed by Bangladesh Institute of Nuclear Agriculture (BINA) against a local one. Three replications of a Randomized Complete Block Design (RCBD) were used where Atshira, Binatil-3, Binatil-4 were the different variations. The experiment’s findings showed that the genotypes significantly differed in terms of days to maturity, height of plant, number of developed branches, number of pods, length of pods, pod breadth, seeds contain per pod, weight of      1000 seeds and yield of seeds. Atshira contained the tallest plant (105.20 cm), whereas Binatil-3 contained the shortest plant (79.53 cm). It was noted that Binatil-4 had the greatest number of plant-1 branches (5.17), whereas Atshira had the least amount (2.12). Additionally, Binatil-3 displayed the highest number of pods plant-1 (95.66) whereas Atshira provided the lowest amount (51.75). Atshira had the largest pod (3.23 cm), whereas Binatil-3 had the smallest (2.48 cm). It was noted that Atshira displayed the greatest number of seeds in pod-1 (76.28). The highest thousand seed weight was recorded in Binatil-4 (3.25 g), whereas the lowest thousand seed weight was in Atshira (2.85 g). The variety Binatil-4 had the highest seed yield (1.36 ha-1), whereas Atshira had the lowest (1.21 ha-1). Among the cultivars, Binatil-3 matured in the fewest days (86), whereas Binatil-4 required the most days (95). At Binatil-4, significant growth and yield performance was found from Kharif-I (summer) season trial. Furthermore, it will be useful for Bangladesh to choose sesame genotypes with high yield potential and future breeding stock.

Knowledge based universal methodology for strengthening of scientific research, writings and publications

ABSTRACT

More reading of related journal articles, writing 2-3 times or more for building a sound scientific article for journal, involvement minimum course work, develop project work and dealing with project, come to touch with a good/renowned scientist and all these are the universal guideline for buildings successful scientist and philosopher. There successful schematic models are the pillars of research covering a strong publication in journal.

Key words: Guideline, scientist, research, philosopher, article publication, journal.

Guideline and suggestions given by renowned scientists and philosophers regarding research and writing of scientific articles for publication in journal

  • Academic teaching and research or research building with professional career is a God gifted award where human strong desires and activities work as a single factor.
  • According to Japanese Professors and scientists good researchers are those they must work most of the times in field, lab. or research related activities where past academic good/strong career is not the factor/criteria for the sound researchers.
  • More involvement in research, more writings and publications make a man true researcher, and ultimately a great one as strong/renowned scientist and/or philosopher.
  • Here two factors work uniformly like knowledge based research (KBR) or research based knowledge (RBK) are important to establish as renowned/great researchers, scientists and philosophers.
  • Dr. H. Brown (author of more than 800 publications) Prof. of Chemistry, Indiana University, USA, was awarded the Nobel Prize in 1979 who was good friend of my supervisor Prof. Paasivirta, Dept. of Chemistry, Univ., Jyvaskyla, Finland. During taking of Nobel Prize in December 1979, he visited our Dept. of Chemistry, (then there I was a PhD student) where I personally discussed about the success and failure of research and building career as good researcher. Prof. Brown then congratulated me for my new invention and discoveries of pesticide residual works and some of my analytical methods for detection of metabolites and residues for food safety against hazardous pesticides in 1976-79. He concluded with few words, “Minimum class load (5-10%), and maximum involvement lab./field/other research (80-90%) and writing and publications (>90%) are the best criteria for developing a perfect/successful researcher where standard journals are encouraged”.
  • Paasivirta (renowned scientist, more than 500 publications, nominated 2-3 times for Nobel prize (unofficial) where his supervisor in Finland was awarded the Nobel Prize in 1943, worked with him at his Dept./lab. at Jyvaskyla, Finland; replied me in 1980 regarding handling of good research and to be good researcher-minor class load for MS/PhD courses, most of the time involvement in research, reading, writing and publishing of articles in journals, participation and presentation of articles related confs./seminars” where I published 30-35 articles in Inter. Journals and participations of more than 20 conferences with him in 1976-84 at different universities of Finland, Norway, England and Ireland.
