A field experiment was conducted at Bilpar village of Sunamganj district in Bangladesh during November 2016 to May 2017 to find out the effects of Triple Super Phosphate (TSP) fertilizer on the growth and yield of boro rice in haor areas. Two factors viz. varieties (BRRI dhan29 and BRRI dhan58) and six TSP fertilizer levels [F1- 85 kg TSP ha-1 (Farmers’ practice), F2- 142 kg TSP ha-1, F3- 127 kg TSP ha-1, F4- 112 kg TSP ha-1 (BARC recommended dose), F5- 97 kg TSP ha-1, F6- 82 kg TSP ha-1] were included in the experiment. The experiment was conducted in the farmers’ field and laid out in a RCBD with three replications. Data were taken on plant height and tillers hill-1 at 15 days intervals. The yield and yield contributing parameters were also taken at harvest. Plant height, number of total tillers, effective tillers hill-1, panicle length, sterile spikelets, 1000 grain weight, grain and straw yield varied significantly due to variety. BRRI dhan58 produced higher number of effective tillers (10.60) and grains panicle-1 (136.9) over BRRI dhan29. BRRI dhan58 produced higher grain yield (8.92 t ha-1) compared to BRRI dhan29 (7.27 t ha-1). All the studied parameters differed significantly with the application of TSP fertilizer except non-effective tillers hill-1. Application of 112 kg TSP ha-1 produced the highest number of effective tillers hill-1 (12.00) and the lowest in farmers practice (7.20). Fertilizer Recommendation Guide based TSP fertilizer (112 kg ha-1) produced the highest grain yield (8.80 t ha-1) of boro rice and the lowest grain yield (7.40 t ha-1) in farmers’ practice. Results of the study elucidated that TSP application at 112 kg ha-1 was effective to improve the rice productivity.

<p>New wetlands field generally has low productivity, so a technology is needed for improve productivity. New Superior Variety (NSV) is a technology that is considered easy to be adopted by farmers, so knowing a NSV that is able to adapt to the characteristics and conditions of new wetlands field is a must. The study of adaptive NSV on new wetlands field in Boven Digoel Regency is still limited so that the NSV recommendation for farmers is also still limited. The purpose of this study was to examine the growth and production of new superior varieties on the new wetlands fields in Boven Digoel Regency. The study was conducted on new wetlands in Asiki Village, Jair District during April-August 2019. Randomized Complete Block Design was employed with 3 replications using Inpari 36, Inpari 37, Inpago Rindang 1, Inpago Rindang 2 dan Inpara 8. The results showed different varieties perform different agronomy characters observed (plant height, number of tillers, panicle length, number of grains per panicle, filled grain, per panicle, empty grain per panicle and 1000 grain weight). Inpari 37 produced 5.3 ton/ha Dried Unhulled Rice, the highest production compared to other varieties, so that it could potentially be developed in Boven Digoel’s new wetlands field. Productivity may still be increased by improving soil fertility conditions.</p>

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.

The research work was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during aman season from July to December 2015 to study the effect of nitrogen fertilizer and weed management on the growth and yield of transplant aman rice cv. BRRI dhan46. The experiment consisted of four fertilizer treatments viz. 0 kg N ha−1 (N0), 40 kg N ha−1(N1), 80 kg N ha−1(N2) and 120 kg N ha−1(N3) and four weeding treatments viz. one hand weeding at 20 DAT (W1), two hand weedings at 20 and 35 DAT (W2), three hand weedings at 20, 35 and 50 DAT (W3), weeding by Japanese rice weeder twice at 20 and 35 DAT (W4) and unweeded control (W5). The experiment was laid out in the randomized complete block design with three replications. The highest plant height (113.00 cm), number of total tillers hill−1 (8.74), number of effective tillers hill−1 (6.18), panicle length (21.98 cm), number of grains panicle−1 (114.20), grain yield (4.00 t ha−1), straw yield (5.25 t ha−1) and biological yield (9.25 t ha−1) were recorded in N2 (80 kg N ha−1) treatment. The lowest plant height (106.00 cm), number of total tillers hill-1 (7.20), number of effective tillers hill−1 (5.00), panicle length (20.70 cm), number of grains panicle−1 (97.60), grain yield (3.52 t ha−1), straw yield (4.46 t ha−1) and biological yield (7.97 t ha−1) were recorded from N0 (No nitrogen fertilizer control) treatment. On the other hand, the highest grain yield 4.23 t ha−1 was observed in three weedings condition because of the highest number of effective tillers hill−1 (6.81), number of grains panicle−1(111.10). The highest straw yield (5.51 t ha−1) was also found in three weeding condition. The lowest grain yield (3.40 t ha−1) was recorded in W5 (unweeded control) treatment. The lowest straw yield (4.31 t ha−1) was also observed in W5 (unweeded control) treatment because of the smallest plant (106.97 cm) and lower number of total tillers hill−1 (7.20). Therefore, 80 kg N ha−1along with three hand weedings at 20, 35 and 50 DAT may be used for obtaining the highest grain and straw yields of BRRI dhan46J. Bangladesh Agril.

To evaluate the effect of Zinc fertilizer on performance of wheat cv. BARI gom30, an experiment was carried out at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2015 to March 2016. The experiment comprised four levels of Zinc (Zn) viz., 0, 1.5, 2 and 2.5 kg/ha. The experiment was laid out in a randomized complete block design with three replications. Application of Zinc (Zn) plant height, number of total tillers/plant, number of effective tillers/plant, spike length, number of fertile spikelets/spike numbers of sterile spikelets/spike number of grains/ spike, grain yield and straw yield were found significant. But there was no significant effect of the treatment on 1000-grain weight. The highest number of total tiller/plant (4.42), number of effective tillers/plant (3.92), number of grains/spike (47.70), 1000-grain weight (47.73 g), grain yield (5.06 t/ha), straw yield (6.21 t/ha) was obtained from 2 kg Zn/ha. The highest plant height (94.08 cm), spike length (9.92 cm), number of fertile spikelets/spike (19.59) and sterile spikelets/spike (3.22) and harvest index (46.16%) were recorded at 0 kg Zn/ha respectively. The control treatment indicated the lowest value for the yield attributing characters except the number of sterile spikelets/spike. Grain yield was found to be significantly and positively correlated with number of grains/spike and straw yield. It is recommended that application of 2 kg Zn/ha is the best for maximum yield of BARI gom30.

Forty advanced breeding lines of rice were studied during T Aman season (rainfed ecosystem) for finding out selection indices, variability and character association for grain yield and its components. All the tested characters were found showing significant variation. The highest genotypic, environmental and phenotypic variances were found in filled grains/panicle followed by plant height. High heritability associated with high genetic advance were obtained in panicles/hill, plant height, filled grains/panicle, 1000-grain weight and grain yield. Genotypic correlation coefficients were higher than the corresponding phenotypic correlation coefficients in most of the cases. Panicle length, panicles/hill and filled grains/panicle showed significant positive correlation with grain yield. Path analysis revealed that filled grains/panicle, panicles/hill and 1000-grain weight had positive and highest direct effects on grain yield. Moreover, panicle length had highest indirect effect on grain yield through filled grains/panicle. Discriminant function analysis revealed that a progressive increase in the efficiency of selection was observed with the inclusion of additional character in the selection index. Among the single variable indices, filled grains/panicle showed maximum relative efficiency over the straight selection for grain yield. The highest relative efficiency was observed with index involving seven characters, days to maturity + panicle length + panicles/hill + plant height + filled grains/panicle + 1000-grain weight + yield (t/ha). However, some of 3-traits, 4- traits, 5- traits, and 6- traits indices were also equally good.DOI: http://dx.doi.org/10.3329/bjpbg.v20i1.17015

This research aims to determine the real interaction between bokashi dose treatment and spacing models on the growth and yield of paddy plants. The study used a 3 x 3 factorial with 3 replications. The first factor was the spacing model which consists of 3 levels, namely J1 = tile spacing model (20 x 20 cm), J2 = Jajar Legowo 4:1 (20 cm x 40 cm x 10 cm), and J3 = Jajar Legowo 2:1 (20 cm x 40 cm x 10 cm). The second factor was the dosage of bokashi fertilizer which consists of 3 levels, namely P1 = 5 tonnes per hectare, P2 = 10 tonnes per hectare, and P3 = 15 tonnes per hectare. The research discovered that there was an interaction effect on plants aged 45 days after planting as well as an increase in yield in the form of an increase in grain weight per plant clump. Model treatment also had a significant effect on plant height at the age of 15 and 30 days after planting. In addition, there were also changes in the number of tillers, productive tillers, seeds per panicle, panicle length, and grain weight per plot for all observed ages. The 4:1 legowo row model treatment resulted in the best growth and production of paddy fields, while the highest production was produced by the legowo row 2:1 treatment. Bokashi dosage treatment was 15 tons per hectare.Isi artikel ini bertujuan mengetahui adanya interaksi yang nyata antara perlakuan dosis bokasi dan model jarak tanam terhadap pertumbuhan dan hasil tanaman padi.

Rice is an important food for humans. In the world, for food purposes white-grain rice varieties are mainly used, but there are varieties in which kernel pericarp is of red, brown, purple or black color. Such rice is more beneficial for health promotion. The current paper has presented the results of genetic analysis of the inheritance of a number of variable quantitative traits in rice hybrid populations of the first and third generations obtained by the hybridization of the varieties ‘Kuboyar’ and ‘Gagat’. The variety ‘Kuboyar’ is medium-sized, with a compact erect panicle, an oval caryopsis and white pericarp. The variety ‘Gagat’ is tall, with a long drooping panicle, a long kernel and black pericarp. The work was carried out on the territory of the OP ‘Proletarskoe’ of the Rostov region in 2018–2020. The analysis of the inheritance of some quantitative traits that have a direct impact on the rice productivity made it possible to establish new inheritance regularities. According to the trait ‘plant height’ there has been identified partial dominance of the largest values of the trait in the hybrids F2 and F3. Allelic differences of 3 pairs of genes were identified in parental forms. The trait ‘panicle length’ showed overdominance of the trait in F2, it was absent in F3, and there were digenic differences in parental forms. The trait ‘number of spikelets per panicle’ demonstrated overdominance of large values and positive transgression. According to the trait ‘1000-grain weight’, the hybrids of both generations were split by the digenic scheme in a ratio of 1:4:6:4:1. There was no dominance in the trait ‘kernel length’; the initial varieties had differences in 2 pairs of genes. According to the trait ‘kernel width’, there was identified incomplete dominance of smaller values, and there was monohybrid split. There have been selected the best plants F3 with a black pericarp, average values of the traits ‘plant height’, ‘panicle length’, ‘1000-grain weight’ and an increased number of grains per panicle for the further breeding process.

Management of applied nitrogen in rice field is one tool that could lead to increase in rice yield, but often ignored by most farmers. The experiment was carried out from April to July 2015 at the Agronomy Field Laboratory of Patuakhali Science and Technology University, Dumki, Patuakhali to find out the influence of different nitrogen management and variety on the yield performance of transplant Ausrice. The study consisted of four levels of nitrogen viz. Control (without N), 30 kg N ha-1, 60 kg N ha-1 and urea super granule @ 52 kg N ha-1 and four Transplanted aus rice varieties viz. KaliHitta, ChaitaBoro, Abdul Hai and Gota IRRI, and was laid out in a split-plot design with three replications. The levels of nitrogen were assigned in the main plot and varieties were allocated in the sub-plots. Nitrogen management, variety and their interactions exerted significant (P ≤ 0.05) influence on plant characters, yield contributing characters and yield of transplanted Aus rice. In the case of nitrogen management, the tallest plant was 161.60 cm, maximum leaf area index(2.97, the highest number of effective tillers hill-115, longest panicle 24.30 cm with the maximum number of filled grains as94.73, 1000-grain weight gave 29.97 g. Grain yield of 2.48 t ha-1 were obtained from USG @ 52 kg N ha-1 and the shortest plant height of 136.90 cm with lowest leaf area index of 1.78, lowest number of effective tillers hill-1 (8.43), shortest panicle (18.84 cm) with the lowest numbers of filled grains panicle-1 (53.18), 1000-grain weight (24.33 g) and grain yield (1.40 t ha-1) were obtained in control (N1=O, kg N ha-1). Among the varieties, ChaitaBoro gave the tallest plant height (151.60 cm) and maximum leaf area index (2.54). While the highest number of effective tillers hill-1 (12.20), longest panicle (22.42 cm) with the maximum number of filled grains panicle-1 (73.50), highest 1000-grain weight (27.41 g) and highest grain yield (2.39 t ha-1) were recorded from Gota IRRI than other varieties. In case of interaction, Gota IRRI Fertilized with USG at 52 kg N ha-1 produced the highest number of effective tillers hill-1 (16.87), panicle length (25.13 cm), number of grains panicle-1 (105.70) and grain yield (3.13 t ha-1). The lowest number of effective tillers hill-1 (8.13), lowest panicle length (17.47 cm) with minimum numbers of filled grains 47.67) and grain yield (1.12 t ha-1) were produced by the interaction of control (N1=O, kg N ha-1) and Kali Hitta. So, cultivation of transplant Aus rice (Gota IRRI) appeared to be the best performance with USG @ 52 kg N ha-1 and recommended to the end users.
