The experiment comprised two factors, viz. (A) foliar supplementation of N, and (B) Zn fertilizer management. Factor A had two levels, viz. (i) no N application (control) (N0), and (ii) foliar application of 2% urea solution at pod formation stage (N1). Factor B had four levels, viz. (i) no Zn application (control) (Z0), (ii) basal application recommended dose (RD) of Zn (Z1), (iii) foliar application of 0.5% ZnSO4.7H2O at pod formation stage (Z2), and (iii) basal application of 50% RD of Zn + foliar application of 0.5% ZnSO4.7H2O at pod formation stage (Z3). All growth parameters (leaf area, branch production and plant height), yield contributing characters (total number of pods m-2, number of fertile pods m-2, number of seeds m-2 and weight of 1000-seeds), and seed and stover yields were significantly affected by N fertilization. The highest values were recorded with foliar application of urea (2%) at pod formation stage. Zn management and the interaction of N and Zn management significantly affected the yield contributing parameters and yields of soybean. However, plant characters were affected neither by Zn nor the interaction. Basal application of 50% RD of Zn + foliar application of 0.5% ZnSO4.7H2O at pod formation stage produced the highest values for all yield contributing characters. Interaction of these N and Zn treatments was also found to be the best combination in terms of these parameters (Table 1). However, foliar N (2% urea) application coupled with a single foilar spray of 0.5% ZnSO4.7H2O at pod formations stage was as good as the previous combination and produced the statistically similar results in all these yield contributing characters. Therefore, for higher seed yield of soybean, 2% urea solution coupled with a single foilar spray of 0.5% ZnSO4.7H2O at pod formations stage is recommended.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73178911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was carried out across five locations (Shyampur and Godagari under Rajshahi district, Nachole at Chapainawabganj, Sapahar at Naogaon and Lalpur at Natore district in north-west Bangladesh) to assess GEI effects on grain yield and its components and to identify high yielding and stable genotypes of wheat for grain yield in the year of 2020-21. Combined analyses of variance for G and GEI were significant for almost all traits. Significant GEI suggested that the performance of genotypes was not consistent across locations, revealing strong influence of environments on the expression of phenotype for all traits. Average over five locations, genotypes G84 (3647 kg ha-1) and G76 (3576 kg ha-1) exhibited maximum values for grain yield and also produced similar tillers m-2 (SPM) and grains spike-1 (GPS) where difference between them was statistically insignificant thus appeared as leading genotypes for yield and production traits. Again, the genotypes G84 and G76 produced statistically insignificant maximum yield in all locations indicating that they are high yielding and wide adapted genotypes. The genotype G80 produced insignificant yield and other yield traits with G76 and G84 across the locations indicating its wide adaptability. However, G26, G69 and G77 with higher grain yield in Shyampur, G53 and G59 in Godagari ,G20 in Lalpur, G3 in Nachole and G8 in Sapahar proved their specific adaptability in particular locations. Among locations, Shyampur and Godagari were identified as highly productive locations in terms of grain yield and positive environmental index. Correlation analysis showed that grain yield had strong positive association with spikes m-2 (r = 0.92**), grains spike-1 (r = 0.72**) and TGW (r = 0.89**). On the basis of mean grain yield and higher positive phenotypic index for SPM, GPS, TGW and GY, G76, the genotypes G84,G76 and G80 were found as high yielding genotypes and thus could be recommended as important breeding materials in upcoming specific breeding program for drought prone north-west part of Bangladesh.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88334084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment consisted of two varieties viz., Beet Palong (V1), Red Ball (V2) and eight organic manures treatments viz., T0 (control), T1 (cow dung @ 15 t/ha), T2 (mustard oil cake @ 0.5 t/ha), T3 (vermicompost @ 10 t/ha), T4 (cow dung @ 7.5 t/ha + mustard oil cake @ 0.25 t/ha), T5 (cow dung @ 7.5 t/ha + vermicompost @ 0.5 t/ha), T6 (mustard oil cake @ 0.5 t/ha + vermicompost @ 10 t/ha), T7 (Cowdung @ 5 t/ha + Mustard oil cake @ 0.15 t/ha + vermicompost @ 3t/ha). The experiment was laid out in a split-plot design with three replications. There was a significant effect of varieties and organic manures on beetroot growth, yield and quality. The highest plant height (35.21 cm) was recorded on the Red Ball variety with Cowdung @ 5 t/ha + Mustard oil cake @ 0.15 t/ha + vermicompost @ 3t/ha (T7) treatment along with a large number of leaves (10.10), highest leaf length (24.33 cm) and breadth (16.03 cm). The root yield of the Red Ball variety was 35.82 t/ha, whereas the root yield of the Beet Palong variety was 25.68 t/ha. In case of organic manures, highest root yield (40.33 t/ha) was measured in T7 treatment whereas the lowest root yield (22.82 t/ha) was found in T2. In combination treatment, Red Ball variety with produced the maximum root yield (48.30 t/ha) in combination with T7 treatment whereas the Beet Palong variety produced the lowest root yield (15.37 t/ha) in combination with T0 treatment. Lower crack percentage (6.67%) and rotten percentage (3.33%) of beetroot were observed in the Red Ball variety (V2) in comparison to Beet Palong (V1). The maximum dry matter content (34.19%) was found in combination treatment V1T5 whereas the minimum dry matter content (16.08%) was observed in V2T0. Therefore, the study indicated that Red Ball variety (V2) in combination with Cowdung @ 5 t/ha + Mustard oil cake @ 0.15 t/ha + vermicompost @ 3t/ha (T7) along with recommended chemical fertilizer may be recommended for better and better quality of beetroot.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84253190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was conducted in factorial design investigating the effect of two biochar particle sizes (less than 1mm and more than 2.8 mm) and three biochar amounts (1%, 2%, and 3% by mass ratio) on nitrate leaching in soil. Our findings revealed significant reductions in nitrate leaching upon the application of barberry biochar. The experimental treatments had a significant effect on nitrate concentration in leached water in both sampling stages. Although the initial sampling indicated non-significant variances between particle size, clear statistical differences emerged in the second sampling. The smaller biochar particle sizes (less than 1 mm) recorded greater reductions by 76.3% in nitrate leaching compared to larger ones (exceeding 2.8 mm) that resulted in 66.2% reduction. Our results indicated that a 1% weight of biochar produced the lowest leaching rate, with reductions of 79.7% in the first sampling and 82.6% in the second sampling. Finer biochar particle sizes (< 1mm) were the most effective at reducing nitrate leaching, which achieved to an 80.9% reduction. Overall, barberry biochar shows potential in mitigating nitrate pollution, enhancing soil quality, and promoting agricultural sustainability. It is important to consider the optimal biochar application rate and particle size to maximize its effectiveness in reducing nitrate leaching while minimizing any potential negative impacts on crop yield. Further research is required to optimize biochar application rates, particle sizes, and long-term effects in diverse agricultural systems. Implementing biochar as a soil amendment holds promise in improving soil health, water quality, and overall sustainability.","PeriodicalId":53074,"journal":{"name":"Fundamental and Applied Agriculture","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135311130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted to assess the effects of plant growth-promoting rhizobacteria on growth and nutrient assimilation of rice. METHODOLOGY: Seeds of transplant Aman rice (cv. BRRI dhan49) were collected from Bangladesh Rice Research Institute (BRRI). Pot experiment was conducted with rice plant inoculated with two PGPR isolates MQ1 (Zinc solubilizing, IAA producing, phosphate solubilizing and N2-fixing) and MQ2 (Zinc solubilizing, phosphate solubilizing and N2-fixing) with addition of three different levels of chemical fertilizers (FR0.0 no fertilizer, FR0.5 half of the recommended dose, FR1.0 full of the recommended dose of fertilizers) following Completely Randomized Design with three replications. Plant height at different days after transplanting, number of tillers hill-1 and biomass yield were recorded. Plant samples were analyzed for N, P, Ca, Mg, S, Fe, Zn, Mn, Cu and Cd contents. KEY FINDINGS: Rice plants inoculated with the PGPR both individually or in consortium along with different doses of fertilizers showed an improved plant growth and increased biomass production. Highest plant height (74.057±3.164 cm) and maximum number of tillers hill-1 (13.000±2.082) were recorded in PGPRMQ1RF1.0 treatment and the highest biomass production (10.275±0.541 t ha-1) was recorded in PGPRCONS.RF1.0. Nitrogen content and uptake of the individual PGPR treated rice plants was also found to be higher in comparison with the uninoculated control plants. Besides these iron and zinc content of the treated rice plants was also found to be higher in comparison with the uninoculated control plants. N (0.268±0.046), P (0.626±0.095), Fe (6.062094±A), Zn (1.237±0.197) and Mn (11.908±1.879) uptake were observed higher in PGPRMQ1RF1.0 treatment.

Two field experiments were conducted during the 2019 and 2020 seasons to study the effect of biochar (BC) as soil applications, compost tea (CT) as foliar applications, and their combination on the growth, yield, and essential oil composition of P. graveolens. The experimental design was a randomized complete block with three replicates. Three biochar rates (0, 5, and 10 t ha-1) and four compost tea concentrations (0, 0.1, 0.2, and 0.3 %) were assigned randomly in plots. Plants were harvested twice; i.e., on 1st May and 30th September, and the following data were recorded for each cut: plant height, leaf area index, fresh herbage yield, oil %, oil yield, and chemical constituents of essential oil. Results indicated that P. graveolens growth parameters and yield components at both cuts were significantly affected by biochar application and foliar application of compost tea, and a significant interaction of these two factors also occurred. All treatments gave significantly the best values of plant height, leaf area index, and fresh herbage yield in addition to essential oil % and oil yield, in comparison with the control treatment. Among treatments, the plants receiving biochar at 10 t ha-1 in combination with compost tea 0.1% could be the best choice. The numerical increase in the abovementioned parameters, in comparison with that of control treatment, reached 115.30, 79.59, 68.85, 66.67 and 181.42 %, in the first cut and 118.66, 80.04, 65.81, 66.67 and 176.35 % in the second cuts for the tested parameters, respectively.

The experiment was laid out in strip plot design with three replications. The treatment consisted of four varieties (Chaite-5, Hardinath-1, Hardinath 1-F1, and Hardinath-3) in horizontal plots and five levels of LCC-based N management practices (Pure LCC, 25% N (basal) + LCC, Recommended dose of fertilizer in three splits, Farmer’s dose, and no nitrogen) in vertical plots. The results showed that Pure LCC-based nitrogen management produced the highest grain yield (6.24 t ha-1) followed by 25% N basal +LCC (5.77 t ha-1). LCC-based treatments produced a significantly higher yield than recommended dose applied in three splits. The higher yield in pure LCC was because of higher yield attributes like effective tillers m-2, higher thousand-grain weight, lower sterility percentage, longer panicle length, and higher panicle weight. Hardinath-3 and Hardinath 1-F1 with pure LCC produced significantly higher yields than other treatment combinations. The spring rice varieties Hardinath 1-F1 and Hardinath-3 were high yielders than Hardinath-1 and Chaite-5. The higher yield of Hardinath-3 was due to higher number of effective tillers m-2, longer panicle length, and higher panicle weight. Similarly, the higher yield of Hardinath1-F1 was mainly due to higher thousand-grain weight and higher number of effective tillers m-2 as compared to other varieties except for Hardinath-3.
