Severe water shortage in many parts of the world has caused enormous yield losses in rice. To continue feeding the increasing number of people who are dependent on rice as staple food, there is a need to address the problem on water shortage. One possible solution may be the application of alternate wet and dry (AWD) water management in rice production. This experiment was conducted to evaluate the growth and yield performance, as well as the profitability of selected lowland rice varieties under AWD water management. An experimental area of 450m2 with Umingan clay loam soil was laid out in randomized complete block design (RCBD) with three replications. Each replication was subdivided into six treatment plots with an area of 20m2 (5m x 4m) each. The treatments were: T1 – Masipag 45 (M45), T2 – Matatag 6 (M6), T3 – Masipag 129-2 (M129-2), T4 – Pinili-1, T5 -SL-8H and T6 – PSBRc-18 (check variety). Results showed that number of days from planting to heading and maturity, fresh straw yield (t ha-1), number of productive tillers per hill, number of filled grains per panicle and grain yield (t ha-1) differed significantly among treatments (p<0.05). Pinili-1 headed and matured the earliest and produced the highest fresh straw yield (t ha-1). However, M-129-2 and Matatag 6 had the highest number of productive tillers per hill, number of filled grains per panicle and total grain yield (t ha-1) which surpassed that of PSBRc18 (check variety). Masipag129-2 and Matatag 6 also gave the highest net profit of Php 23,805.00 per hectare.

For better rice productivity there is a need to address the problems on water shortage and nutrient management. This study was conducted to evaluate the growth and yield performance and the interaction effect between water and fertilizer applications on irrigated lowland rice (NSIC Rc218); to determine the relationships of other plant characters which are contributory to yield; and to assess the cost and return of irrigated lowland rice production ha-1 as influenced by water and fertilizer applications. Two methods of water application were evaluated and results showed that alternate wet and dry methods (AWD) were able to save 19.02% of the total water received by the rice plants compared to continuous flooded condition. Grain yield of irrigated lowland rice (NSIC Rc218) was significantly (p<0.05) increased by 1.84 t ha-1 which is higher by 35% when applied with recommended inorganic fertilizer at the rate of 100-60-60 kg N, P20 and K20 ha-1 (T2) than that of unfertilized plants (T1). Correlation analysis showed that grain yield is positively correlated to the number of productive tillers panicle, panicle length (cm), % filled spikelet panicle-1, weight of 1000 grains (g) and LAI but not on the number of spikelets panicle-1. Plants applied with 100-60-60 kg N, P20 and K20 ha-1 (T2) and those applied with 75% RRIF + 25% RRVC (T4) generated the highest net income of PhP 66,915.00 ha-1 and PhP 60,440.00 ha-1 respectively, than unfertilized plants of PhP 40,375.00 ha-1.

The experiment was accomplished during the period from November 2018 to May 2019. It was completed in a randomized complete block design (RCBD) with three replications. The treatments assigned in a factorial arrangement of 2 × 4, with 2 varieties of rice (V1-BINA dhan 8, V2- BINA dhan 10) and 4 integration of vermicompost, biochar, and urea (T1: Vermicompost-2.5 t ha-1, T2: Vermicompost-2 t ha-1+ Biochar 0.5 t ha-1, T3: Vermicompost-1.5 t ha-1+ Biochar 1 t ha-1 and T4: Vermicompost-1.5 t ha-1 + Urea-150kg ha-1/0.15 t ha-1). Data were collected to analyze growth and yield contributing characters of boro rice. All the parameters were not statistically significant to differ. According to variety highest grain (3.73 t ha-1) and straw (2.8 t ha-1) yield was found from BINA dhan 10 in comparison with BINA dhan 8. In case of integrated application of vermicompost, biochar and urea, superior grain and straw yield were obtained from T4: Vermicompost-1.5 t ha-1 + Urea-0.15 t ha-1 whereas lowest grain yield (3.01 t ha-1 recorded from integrated application vermicompost and biochar. In combine maximum grain (4.92 t ha-1) and straw (4.40 t ha-1) yield was noted from BINA dhan 10 alone with integrated application of vermicompost and urea whereas the lowest data (grain: 2.50 t ha-1; straw: 1.64 t ha-1) was found from BINA dhan 8 along with vermicompost and biochar.

Boro Rice

An experiment was conducted to find out the effect of variety, date of transplanting and its interaction on the growth and yield performance of high yielding Boro rice. The experiment comprised five varieties viz., BRRI dhan28, BRRI dhan58, BRRI dhan67, BRRI dhan69, BRRI dhan74 and five dates of transplanting viz., 15 December, 30 December, 15 January, 30 January and 15 February. The experiment was laid out in a randomized complete block design with three replications. Results revealed that growth parameters, crop characters, yield components and yield were significantly influenced by variety, date of transplanting and their interactions. The leaf area index (LAI) and dry matter production hill-1 were highest in BRRI dhan69 when transplanted on 15 January whereas the lowest value was found in BRRI dhan28 when transplanted on 15 February. The number of effective tillers hill-1 (11.80), number of grains panicle-1 (130.90), 1000-grain weight (22.07 g), grain yield (4.96 t ha-1) and straw yield (6.64 t ha-1) were highest in BRRI dhan69 whereas corresponding lowest values were recorded in BRRI dhan28. The crop transplanted on 15 January produced the highest number of effective tillers hill-1 (12.81), highest number of grains panicle-1 (131.20), heaviest 1000-grain weight (21.93 g), highest grain yield (5.36 t ha-1) and highest straw yield (7.71 t ha-1). In case of interaction, the highest grain (5.90 t ha-1) and straw yields (7.87 t ha-1) were recorded in BRRI dhan69 transplanted on 15 January whereas the lowest grain and straw yields were recorded in BRRI dhan28 transplanted on 15 February. Therefore, it can be concluded that BRRI dhan69 along with 15 January transplanting appears as the promising combination in terms of grain and straw yields.

An experiment was conducted in the Agriculture Field Laboratory, Noakhali Science and Technology University (NSTU) to evaluate the effects of age of seedlings on the yield and growth performance of transplanted Aus (T. Aus) rice variety from April 2019 to July 2019. The experiment was carried out assigning four age of seedlings (T1 = 22-day old, T2 = 24-day old, T3 = 27-day old, T4 = 30-day old) and two rice varieties (V1 = BRRI dhan83, V2 = BRRI dhan65). The experiment was laid out in a Randomized Complete Block Design with three replications. In case of variety, the highest plant height (102.108 cm), the highest grain yield (2.643 t/ha), and the highest harvest index (32.317%) were obtained in BRRI dhan83 where the lowest plant height (87.804 cm), the lowest grain yield (2.431 t/ha) and the lowest harvest index (32.068%) were obtained in BRRRI dhan65. The age of seedlings had significantly affected total tillers/hill, effective tillers/hill, panicle length in T. Aus rice variety. The highest plant height (98.16 cm), straw yield (6.122 t/ha), the maximum number of effective tillers/hill (15.347) were obtained in 24 days old seedlings. The highest grain yield (2.634 t/ha) was obtained from 27 days old seedlings, and the highest harvest index (33.88%) was obtained from 22 days old seedlings. The lowest grain yield (2.429) was obtained from 24 days old seedlings, and the lowest panicle length (13.753 cm), harvest index (30.467%), and the minimum number of effective tillers/hill (13.753) were obtained from 30 days old seedlings. The lowest straw yield (5.075 t/ha) and plant height (93.16 cm) were obtained from 22 days old seedlings. In case of interaction, the highest plant height (104.667 cm) and the harvest index (34.86%) were observed in BRRI dhan83 at 27 days old seedlings. The highest straw yield (5.805 t/ha) was observed in BRRI dhan65 at 30 days old seedlings. The maximum number of effective tillers/hill (18.519) was observed in BRRI dhan83 at 24 days old seedlings. The highest grain yield (2.94 t/ha) was observed in BRRI dhan83 at 22 days old seedlings. The lowest plant height (80.67 cm) was observed in BRRI dhan65 at 27 days old seedlings. The minimum number of total tillers/hill (17.01) was observed in BRRI dhan83 at 22 days old seedlings; lowest panicle length (20.78 cm), the minimum number of grains/panicle (68.07) were observed in BRRI dhan65 at 24 days old seedlings; 1000 grains weight (22.76 g), the lowest grain yield (2.18 t/ha) were observed in BRRI dhan83 at 24 days old seedlings; the lowest straw yield (4.54 t/ha) was observed in BRRI dhan65 at 22 days seedlings old and lowest harvest index (29.09%) were observed in BRRI dhan65 at 30 days old seedlings. Based on the above results, it may be concluded that almost all of the yield and yield contributing characters of T. Aus rice performed best under the interaction between age of seedlings 22 days old seedlings and the variety BRRI dhan85.

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from July to December 2011 to evaluate the effect of variety and placement method of urea super granule (USG) on the yield performance of T. aman rice varieties. The experiment consisted of three aman rice varieties viz., Pajam, BR11, BRRI dhan40 and four placement methods viz., broadcasting method of prilled urea (PU), USG placement by hand, by BAU USG applicator and by BARI USG applicator. The experiment was laid out in a randomized complete block design with four replications. The highest value of grain yield (5.13 t/ha), straw yield (5.90 t/ha) and biological yield (11.04 t/ha) were found in BR11. On the other hand, the lowest grain yield (3.54 t/ha) was produced in variety Pajam. The highest grain and straw yields (5.13 and 5.21 t/ha, respectively) were obtained from the hand placement method of USG. Regarding the interaction of variety and USG placement method, BR11with hand placement method appeared as the best method among others. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21183 J.

Given the high costs of agricultural production, especially due to the price of fertilisers, particularly nitrogen, the use of inoculants to supply nitrogen to soybean crops is a widely recommended practice. The objective of this study was to evaluate the feasibility of applying inoculants through seed and planting furrow in soil previously cultivated with soybean and Brazilian native “cerrado” biome soil under greenhouse conditions. Seven treatments were tested: 1) inoculation via seed (inoculant + fungicide + micronutrient), 2) treatment via seed (fungicide + micronutrient), 3) control (only seed), 4) inoculation via furrow-dose 1 (recommended dose), 5) inoculation via furrow-dose 2 (twice the recommended dose), 6) inoculation via furrow-dose 3 (three times the recommended dose) and 7) inoculation via furrow-dose 1 + seed inoculation. We evaluated plant height, fresh and dry matter weight of the aerial part and nodules, number of total, viable and non-viable nodules, number of pods per plant and grain yield. Inoculation was more effective when used in cerrado soil, but soybean performance in treatments without inoculation was higher in previously cultivated soil. Application through furrow proved to be a viable practice due to the similarity of the results obtained with the traditional application by seed.
