Correction: In the last line of the abstract, the word 'increase' was replaced with the word 'reduced' on 25th November 2015. The correct sentence now reads "The application of PRH, Calsol and Magic Growth significantly reduced rice yield than that obtained with recommended fertilizer dose."AbstractInherent soil fertility and application of exogenous fertilizer generally affect rice yield. Fertilization would be soil fertilization or foliar feeding through leaf area. Plant growth promoting substances also improve plant performance through modulation of its growth and yield. The study was conducted at BRAC Agricultural Research and Development Center (BARDC), Gazipur. The aim of the study was to find out the growth and yield of Boro rice as influenced by plant revitalization hormone (PRH) and liquid fertilizer Calsol and Magic Growth during dry season 2012-13 using randomized complete block design with three replications. Treatment consists of; T1=Recommend fertilizer dose of NPKS and Zn (Control), T2=T1+ recommended PRH, T3=T2 + half of the PRH, T4=Half of doses of T1 + PRH, T5=PRH, T6=Recommended fertilizer dose of NPK with three N top dressed along with Calsol, T7=Recommended fertilizer dose of NPK with 1st and 3rd split of N application and along with three split of Calsol application, T8=Recommended dose of liquid fertilizer Magic Growth. The effect of different treatment combinations of PRH and liquid fertilizer Calsol and Magic Growth showed significant difference (p<0.05) in panicle m-2, unfilled grain panicle-1, total grain panicle-1, and grain yield. However, none of the treatments out yielded the existing fertilizer application method. The application of PRH, Calsol and Magic Growth significantly reduced (corrected on 25th Nov. 2015) rice yield than that obtained with recommended fertilizer dose.Bangladesh Rice j. 2015, 19(1): 33-39

The experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA) sub-staion, Tajhat, Ranpure, using potato-Boro-T. aman rice cropping pattern with an objective to evaluate the direct and residual effects of sulphur and zinc on the growth, yield and nutrient uptake by the crops. The surface soil was sandy loam texture, pH 6.3, organic matter 1.24%, available sulphur 6.62 ppm and available zinc 0.45 ppm. The experiment comprised of eight treatments for potato S15Zn2 (T2, T4 and T8, S8Zn1 (T5 and T6)and S0Zn0 (T1, T3 and T7), for boro rice S20Zn4 (T3, T5, T6 and T7) and S0Zn0 (T1, T3, T4 and T6). The experiment was laid out in a randomized complete block design with three replications. Average tuber yield of potato (var. cardinal) varied from 28.29 to 32.86 t ha-1 with the highest yield in S15Zn2 treatment (100% recommended dose) and the lowest was in the S0Zn0 treatment (control). In the second crop (Boro rice), growth and yield attributes, grain and straw yields responded significantly to S and Zn applied either in the first crop or in both crops. The average grain yield varied from 3.51 to 5.27 t ha-1 over the treatments. In the third crop (T. aman rice), the grain and straw yields responded significantly to S and Zn applied either in the first and second crop or in the third crops. The grain yield of T. aman rice varied from 2.96 to 4.46 t ha-1 over the treatments. The growth and yield contributing characters were also significantly influenced by the treatment. There was a significant direct and residual effect of the treatments on S and Zn uptake by the crops.DOI: http://dx.doi.org/10.3329/pa.v19i1.16987 Progress. Agric. 19(1): 33 - 38, 2008

A field experiment was conducted at Kalikapur village of Kaliganj upazila under Satkhira district in order to observe the effects of flooding duration and additional application of K and S on transplanted boro rice cv. Binadhan-8 during January - May 2013. The experiment was laid out in a split-plot design where the main plots comprised of five flooding levels viz. continuous flooding (W1), flooding for 10 days (W2), flooding for 20 days (W3), flooding for 30 days (W4), flooding for 40 days (W5), and the sub-plots of four additional (over the recommended dose) nutrients rates viz. S43 + K25 (T1), K38 (T2), S32 + K38 (T3), and K50 (T4), with three replications. The duration of flooding showed significant positive effect on the yield and yield components of boro rice cv. Binadhan-8. The highest values for plant height (106.8 cm), panicle length (28.4 cm), number of plants hill-1 (15.3), grain yield (4.8 t ha-1) and straw yield (6.5 t ha-1) were recorded in continuous flooding (W1) while these values were decreased with the decrease in the duration of flooding from 40 days to 10 days. Additional application of K and S also significantly influenced all of the parameters. Results revealed that the highest values for plant height (102.8 cm), panicle length (26.6 cm), plants hill-1 (15.4), 1000-grain weight (23.9 g), grain yield (4.8 t ha-1) and straw yield (6.1t ha-1) were obtained from T3 where S and K were applied @ 32 and 38 Kg ha-1 in addition to the recommended fertilizer rate. The interaction of flooding and nutrients significantly manipulated the yield and yield attributes. Due to interaction of flooding and nutrients, the highest growth and yield was observed in continuous flooding with S32 + K38 (W1T3). The results indicated that the flooding with fresh water and use of additional nutrients (K and S) had a remarkable effect in growing boro rice cv. Binadhan-8 in saline soils of Bangladesh.Res.

Boro Rice

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

For sustainable boro rice production in Bangladesh, a balanced fertilization to improve the current soil condition caused by mono-application of inorganic fertilizers and appropriate rice variety selection are very crucial. Therefore, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the boro season of December 2016 to May 2017 to evaluate the effect of integrated nutrient management on two boro rice cultivars. The varieties were BRRI dhan28 and BRRI dhan29 and eight kinds of nutrient management viz., control (no fertilizers), recommended dose of inorganic fertilizers (120-60-40 N, P2O5, K2O kg ha-1 + gypsum 60 kg ha-1 and ZnSO4 @ 10 kg ha-1), full dose of poultry manure @ 5 t ha-1, cowdung @ 10 t ha-1, poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of other inorganic fertilizers, cowdung @ 5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers, poultry manure @ 2.5 t ha-1 + 75% prilled urea and full dose of inorganic fertilizers, and cowdung @ 5 t ha-1 + 75% prilled urea and full dose of other inorganic fertilizers. The experiment was laid out in a split plot design with three replications. Result showed that, yield and yield components of boro rice were significantly influenced by variety, nutrient management and interaction of variety and nutrient management. In respect of grain yield, BRRI dhan29 produced the maximum yield (5.46 t ha-1). BRRI dhan28 showed poor performance with all characters and gave the minimum yield (4.07 t ha-1). In case of nutrient managements, the highest yield and yield component were obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers and produced the maximum grain yield (5.70 t ha-1). In the interaction of variety and integrated nutrient management, the highest grain yield (6.83 t ha-1) and straw yield (7.61 t ha-1) was obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers with BRRI dhan29 variety. So, BRRI dhan29 with 2.5 t ha-1 poultry manure + 50% prilled urea and full dose of the recommended inorganic fertilizers might be a promising practice for boro rice cultivation.
