Aims: To assess the suitability of short duration high yielding rapeseed-mustard variety(s) cultivation in the haor (wetland) areas. Study Design: Randomized complete block (RCB). Place and Duration of Study: Farmers’ field of Lalakhal, Jaintapur Upazila of Sylhet, Bangladesh during November 2014 to February 2015. Methodology: The treatments included in the experiment were seven rapeseed-mustard varieties viz.  i. Tori-7, ii. BARI sarisha-13, iii. BARI sarisha-14, iv. BARI sarisha-15, v. BARI sarisha-16, vi. advanced line Nap-205 and vii. BINA sarisha-4. Design of the experiment was randomized complete block (RCB) with three replications. Results: The results revealed that BARI sarisha-16 produced the highest seed yield (1.99 t ha-1), but it took the maximum days (92) to maturity. The variety BARI sarisha-15 produced the second highest seed yield (1.78 t ha-1) closely followed by BINA sarisha-4 (1.75 t ha-1) and BARI sarisha-13 (1.68 t ha-1). The lowest seed yield (1.53 t ha-1) was obtained from the variety Tori-7 which was statistically similar to that of BARI sarisha-14 (1.59 t ha-1) and Nap-205 (1.68 t ha-1). Tori-7 took the minimum days (74.7) to maturity while BARI sarisha-15 took 77.7 days. Conclusion: Variety BARI sarisha-15 could be a good option for haor areas for cultivation in medium low land before Boro rice after recession of rainwater, as it took less duration to maturity (77.7 days) with good seed yield (1.78 t ha-1).

An attempt was taken to transform Aman-fallow-Boro cropping pattern into Aman-rapeseed and mustard-Boro for three years beginning from Rabi 2011-12. Two components viz. Bangladesh Agricultural University, Mymensingh (BAU) and Bittohin Chashi Somaj Kallayan Sangstha (BCSKS) executed the programme under the leadership of BAU. Three upazillas viz. Mymensingh Sadar, Muktagacha & Haluaghat of Mymensingh district were under BAU component. Whereas, the upazillas Bagha of Rajshahi, Ishwardi of Pabna and Lalpur of Natore districts were under BCSKS component. A total of 1200 farmers (300+400+500 for 1st, 2nd & 3rd years) were taken into consideration to grow rapeseed and mustard in between Aman & Boro. Each of the farmers were provided with 1kg rapeseed and mustard seeds, necessary fertilizers, insecticide, fungicide & irrigation costs. Five rapeseed and mustard varieties namely BARI sarisha 14 & 15, BINA sarisha 4 & 7 and Unnata Tori 7 were used. Before rapeseed and mustard cultivation, all the farmers grew Aman rice &Boro rice after harvesting it. Among the five rapeseed and mustard varieties BARI sarisha 14 & 15, BINA sarisha 4 and Unnata Tori 7 were found to be suitable for the cropping pattern Aman-rapeseed and mustard-Boro. These varieties matured between 76.9 to 84.1 days. Per hectare seed yield of the varieties ranged from 1266.5 kg (Unnata Tori 7) to 1822.0 kg (BARI sarisha 14) with an average of 1544.6 kg. On an average per hectare cost of production, gross income & gross return from rapeseed and mustard were tk. 27770, 78180 and 50471, respectively. On an average, over three years gross income and gross return obtained from Aman and Boro rice were tk. 52,273 &22237 and tk. 71,138 & 30,935 per hectare, respectively. Thus, an additional income of tk. 50471 obtained by the farmers for growing rapeseed and mustard in between Aman & Boro over that of Aman & Boro only, and cropping intensity of the farmers raised into 300%.J.

CORRECTION: Due to a number of formatting and layout issues, the PDF of this paper was replaced on 10th October 2016.The most sensitive stages of Boro rice against the low temperature are agronomic panicle initiation (API), reduction division (RD) and flowering/anthesis. The critical low temperature is growth stage specific. The time and intensity of the critical low temperature during Boro season has a direct impact on the growth and yield of a crop. Therefore, it is necessary to understand the probability of the critical low temperature with respect to the growth stages to have a good planning for safe harvest. Long term weekly low temperature data have been used to estimate the probability of falling low temperature on those stages and the return period was computed. The growth durations of 1- and 30- November seeded Boro rice crop from 45-day-old seedling of BRRI dhan28 (short duration) and BRRI dhan29 (long duration) are considered to observe the probability. A Boro crop encountering critical low temperature is appeared to suffer from cool injury. The extent of cool injury depends on the nature and duration of low temperature and diurnal change of low (night) and high (day) temperature. The critical low temperature for a rice crop at API, RD and anthesis are 18, 19 and 22°C, respectively. Boro rice is grown between November and May. The low temperature occurs from October to early March. There is, therefore, the probability of low temperature occurrence from the crop establishment to the flowering stage is a great concern. The probability of experiencing stage-wise critical temperature approaches to 100% for early established and short duration crop. However, the late established and long duration crop has the probability little less than the early and short duration crop. In a study it has been observed that short duration BRRI dhan28 having 64.6% sterility to yield 2.5 t ha-1 and BRRI dhan29, 40.8% sterility to yield 6.5 t ha-1. The percentages of corresponding sterility for late established crops were 35.9 and 32.8%. Irrespective of growth duration, the yield is affected a little of the late established crop. Despite low temperature along with the reproductive phase, the late established crop is quite safe due to the parallel high (day) temperature (31-35°C). The high maximum temperature appears to play an important role through the alleviating effect of low temperature. But for early-established particularly short duration variety could not escape the low temperature at some of its sensitive growth stages as the high temperature appears to stay a several degree low (27-29°C) at that time. The low level of high temperature is appeared to drag down the low temperature to aggravate the growth and development of a crop. Therefore, not only the variation of high temperature of the day but also the variation of critical low temperature might have some role in alleviating effect of cool-injury. The periodic return of critical low temperature (10-15°C) during the reproductive stage may occur every year or every alternate year depending on the time across the cropping season and the region as well. Therefore, the critical low temperature, the high temperature during the low temperature period, periodic return of the critical low temperature with respect to growing region and concerned factors should be a consideration for planning a Boro crop.Bangladesh Rice j. 2015, 19(2): 19-27

An experiment was conducted in five farmers’ field in Dingaputa haor of Purba Tetulia village, Mohangonj Upazila in Netrakona district during the period from 20 July 2010 to 15 May 2011. The objective of the study was to determine the feasibility of growing short duration vegetable and oil crops in seasonal fallow of Boro rice-Fallow-Fallow cropping patterns in terms of both combined yields and economic performance. Six short duration vegetables such as potato, red amaranth, stem amaranth, spinach, radish and mustard were the first crops and Boro rice (var. BRRI dhan28) was the second crop. Thus there were six types of cropping patterns Potato-Boro rice- Seasonal flood, Red amaranth-Boro rice- Seasonal flood, Stem amaranth-Boro rice- Seasonal flood, Spinach-Boro rice- Seasonal flood, Radish-Boro rice- Seasonal flood and Musturd-Boro rice- Seasonal flood. The agronomic productivity (rice equivalent yield t ha-1) of the cropping patterns Potato-Boro rice- Seasonal flood, Red amaranth-Boro rice- Seasonal flood, Stem amarnth-Boro rice- Seasonal flood, Spinach-Boro rice- Seasonal flood, Radish-Boro rice- Seasonal flood and Mustard-Boro rice- Seasonal flood were 22.42, 15.47, 17.04, 17.79, 22.11 and 11.56 t ha-1, respectively with economic productivity (gross return Tk ha-1) of 364162.50, 251712.50, 276900.00, 292012.50, 359125.00 and 187850.00, respectively and the benefit cost ratio of 1.88, 1.52, 1.65, 1.69, 1.75 and 1.12, respectively From diversification practices in Dingaputa haor ecosystem Potato-Boro rice- Seasonal flood and Radish-Boro rice- Seasonal flood cropping patterns were found to be the most dominant cropping patterns in economic terms.

Food security is the crucial global issue, especially in developing countries like Pakistan. Since edible oil is an essential food item, its persistent paucity in the country and huge import for meeting domestic requirements, has attained it second largest import item after petroleum products. The aim of present study is qualitative and quantitative evaluation of newly developed short duration and drought tolerant canola quality Brassica juncea lines ZBJ-06012 and ZBJ-08051 to overcome the unfavorable edible oil situation in the country. Thirteen lines were evaluated in randomized complete block design (RCBD) for seed yield, oil quality, maturity period and drought tolerance under different agro-climatic zones both in irrigated and arid areas across the Punjab province at eight locations in Micro Yield Trials during Rabi season 2012-13 and 2013-14. Presently, grown non-canola mustard varieties Khanpur Raya and Anmol Raya were used as check varieties. Brassica napus cultivars Punjab canola and Faisal canola were also included in the trials for comparison study of mustard and rapeseed genotypes. Data for all traits under observation was analyzed through Principle Component Analysis (PCA) to evaluate the best performing lines in irrigated as well as in rain fed areas. Principal Component Analysis showed first 2 PCs having Eigen value >1 explaining 76.4% and 72% of the total variation at irrigated areas and rain fed areas respectively. The mean seed yield was also compared by Least Significant Difference (LSD) test to study the significance at 5% probability level. Canola quality B. juncea lines ZBJ-06012 and ZBJ-08051 have shown good adaptability, early maturity, non-shattering, disease and drought tolerance traits with high yield potential in comparison with presently grown Brassica napus cultivars ?Punjab Canola? and ?Faisal Canola?. Due to these prominent features, these lines have a great scope for motivating farmers to grow canola quality B. juncea when compared with B. napus and non-canola B. juncea. Future challenges demand further development of high yielding, short duration and aphid tolerant mustard cultivars having high oil content and canola quality. There is a great potential of exploiting genetic variability in the existing B. juncea material to achieve the aforesaid goals by using conventional plant breeding techniques.

This experiment was carried out to breed promising brown anther type male sterile lines of carrots having the desirable characteristics of higher seed yield and stable phenotypic expression of male sterility. Brown anther type male sterile lines used for this experiment had been derived from the male sterile sources selected from the seed multiplication plots of Shin Kurota cultivar in 1972. Brown anther type male sterile lines are, in general, good seed yielders but frequently show unstable phenotypic expression of male sterility as compared to petaloid type male sterile lines. Through several years of selection for male sterile lines and plants, brown anther type male sterile lines with good seed-yielding potentials and stable phenotypic expression similar to petaloid type were developed. Outline of the breeding scheme, potential benefits of these newly bred MS lines, etc. will be discussed.

The experiment was conducted in the Boro season of 2016-17, at Bangladesh Rice Research Institute (BRRI) farm under the Agro Ecological Zone (AEZ 28) Modhupur Tract. CN6 is a high spikelet bearing early maturing advanced line of rice but low in spikelet fertility. Supplemented nutrient management was examined to increase its spikelet fertility. Five treatments were used in this experiment. The treatments were as follows: T1 = BRRI recommended fertilizer dose + MgO @ 0.05%, T2 = BRRI recommended fertilizer dose + 60 g MoP + 60 g elemental S (80% wp) + 20 g ZnSO4, T3 = BRRI recommended fertilizer dose + Boron @ 5 ppm, T4 = BRRI recommended fertilizer dose + Copper @ 5 ppm) and T5 = BRRI recommended fertilizer dose alone. The experiment was conducted in Randomized Complete Block design with three replications. The results revealed that Treatment T3 (BRRI recommended fertilizer dose + Boron @ 5ppm) produced the more number of grains per panicle with an average of 201 which is 19.9% higher number of grains per panicle over the BRRI recommended fertilization under the treatment of T5. However, higher grain yield were recorded in treatment T3 compare to the control treatment T5 (BRRI recommended fertilization). Taken together, our results suggested that BRRI recommended fertilization alone with supplemented nutrient management, especially boron, significantly increased the spikelet fertility of the CN6 advanced line of Boro rice resulting higher yield.

An experiment was conducted at farming system research and development (FSRD) site, Jalalpur and multi location testing (MLT) sites, Zokigonj and Moulvibazar during 2013-2015 to evaluate the suitable varieties (genotypes) of French bean for maximize the seed yield of the farmers. The experimental design was a randomized complete block (RCB) with 6 dispersed replications. Eight bush bean genotypes were tested of which 3 were developed by BARI (var. BARI Jharsheem-1, BARI Jharsheem-2, BARI Jharsheem-3), five local accessions: Local-1(black), Local-2 (white colour with chocolate spot at hylum), Local-3 (coffee colour), Local-4 (coffee colour with few chocolate spots) and Local-5 (black with chocolate colour spots). The seed yields were varied significantly among the genotypes. All the local French bean lines performed better and produced higher seed yields compared to BARI developed varieties. The maximum seed yields 2.66, 3.48 and 2.05 t ha-1 was produced by Local-4 and Local-5 at Jalalpur, Zakigonj and Moulvibazer, respectively. So, Local-4 and Local-5 variety as the most promising one due their relatively good plant vigor and high seed yield potentiality.Bangladesh Agron. J. 2016, 19(1): 37-44
