The field experiment cultivating wheat during the winter season from November 2014 to March 2015 was conducted in the “North Eastern Barind Tract Soils” at Kushadaha, Nawabganj, Dinajpur in Bangladesh. The wheat variety BARI Gom 26 was selected in focusing to evaluate the effects of organic amendments using poultry manure (PM) and cow dung (CD) on the growth, yield and nutrient uptake by the plant. The texture of the field soil was clay with acidic nature (pH 5.61). The trials comprise three treatments following a randomized complete block design (RCBD) replicated thrice. Results showed that significantly greater plant height, number of tillers per hill and straw yield were 98.10 cm, 3.66 and 5425 kg/ha respectively in receiving the treatment T2 than T3 (95.66 cm, 3.38 and 4483 kg/ha) and T1 (control). Spike length, 1000 grain weight and grain yield were 9.23 cm, 39.81 kg/ha and 3100 kg/ha respectively also higher in T2 treatment than T3 (8.76 cm, 38.51 kg/ha, 3091 kg/ha) with no statistical differences among them. Therefore, the treatment T2 (PM) comprised of poultry manure and NPK exhibited as the best treatment for producing the highest in all growth and yield parameters of wheat. In wheat grain, the content of N, P, K, S, Mg, Zn and B ranged from 1.080% to 1.380% N, 0.390% to 0.398% P, 0.780% to 0.840% K, 0.079% to 0.111% S, 0.181% to 0.187% Mg, 25.56 to 29.77 ppm Zn and 10.12 to 12.54 ppm B. Similarly in straw, nutrients content ranged from 0.220 to 0.300% N, 0.045% to 0.074% P, 0.970% to 1.250% K, 0.152% to 0.191% S, 0.097% to 0.101% Mg, 10.78 to 13.23 ppm Zn and 27.98 to 2989 ppm B. Therefore, organic amendment with 5-ton cow dung (CD) ha-1 with a recommended dose of NPK significantly increased the content of N, S, Mg, Zn and B in the grain and straw of wheat. Alternatively, the poultry manure treatment with NPK significantly increased the content of P and K in the grain and straw of

Agricultural Sciences 2017年第2期8卷 183-193页

作者： Abul Kalam Azad Humayun Kabir touria el-jaoual eaton Edward Binod Soren Department of Crop Science & Technology Rajshahi University Rajshahi Bangladesh Department of Horticulture Lincoln University of Missouri Jefferson City USA

Potatoes have to be stored after harvest for a shorter or longer period in order to maintain even supply to the market throughout the year for direct human consumption as well as for the processing industry. The present study focused on the storage potentialities of six exotic varieties of potato viz., Diamant, Cardinal, Granola, Felsina, Provento and Asterix at farmers’ condition. The experiment was conducted during winter (December to March) for cultivation, and spring and summer (March to August) for storage at Domar Foundation Seed Potato Production Farm, BADC, Nilphamari, Bangladesh. Results revealed that there were significant variations in storage behavior among the varieties of potato tubers. Asterix showed minimum weight loss (7.10%) which was statistically identical with Cardinal (7.85%) while it was maximum in Felsina (18.83%) followed by Provento (13.41%) during four months storage conditions practicing by farmers (farmers’ conditions). In respect of rotting, significantly highest degree was found in Felsina (18.72%) followed by Provento (15.01%) and the lowest was in Asterix (2.02%) identically similar with Granola (2.22%). The highest percentage of water loss was found in Provento (27.01%) and the lowest was recorded in Asterix (17.03%). Dormancy period and sprouts per tuber were found highest in Asterix (70 days and 9.67) while the lowest dormancy was in Diamant (56 days) and the lowest sprouting was in Granola (2.50). Asterix was found to produce significantly highest amount of dry matter content (20.50%) along with higher amount of edible stored tubers (80.21%) compared to those of other varieties at the end of four months storage. Under the same condition, Diamant was the second highest producer of dry matter (20%) which was statistically similar with Asterix, and had good storage ability that retained 69.07% edible tubers, whereas Felsina contained the lowest amount of dry matter (16%) and showed poor storage ability retaining 55.85% edible tubers

Growth and development of komatsuna (Brassica rapaL. Nothovar) in NFT (nutrient film technique) system, as influenced by natural mineral

引用

Agricultural Sciences 2013年第7期4卷 1-7页

作者： Abul Kalam Azad Katsumi Ishikawa Juan Carlos Diaz-Perez touria el-jaoual eaton Noriko Takeda Department of Horticulture University of Georgia Tifton USA Department of Plant Soil and Insect Sciences University of Massachusetts Amherst USA Laboratory of Biological and Environmental Systems Kochi University Nankoku-shi Japan

The cultivation of komatsuna (Brassica rapa L. Nothovar) was carried out hydroponically using a nutrient film technique (NFT) system inside a greenhouse, applying a quartz porphyry (QP) treated nutrient solution. Quartz porphyry is a natural mineral containing many substances that easily ionize with water to improve water quality. Different growth attributes of komatsuna such as leaf length, leaf width and plant fresh weight increased in plants that received QP treated nutrient solution. The coefficient of variation was smaller for QP treated nutrient solution plants when compared to the control. High light intensity, long duration of solar radiation and higher temperatures in the summer (July-Aug.) promoted plant growth compare to winter (Dec.-Feb.). In contrast, plants grown in the winter accumulated more fresh weight compare to plants grown in the summer. Results also showed that the rapid exchange of ion in the nutrient solution due to the QP treatment enabled the solution to maintain the ion balance, and thus plants grew uniformly and vigorously. The cations Na+ and Ca2+ and the anions Cl- and were dominant and made the media saline. There was a decrease of Na+ ion concentration in the recirculating nutrient solution (NFT) due to ion exchange by QP. Results suggest that water treatment with QP could be used for production of high quality vegetables.

The investigation was carried out in focusing the genetic variability for different traits of wheat influenced by heat tolerance mechanism to find out relationships among phenological, physiological and yield contributing traits. Spring wheat cultivar of 25 genotypes were selected and cultivated under late sowing condition at the Regional Wheat Research Institute, Shympur, Rajshahi, Bangladesh from December, 2016 to April, 2017. Significant variability among the genotypes exposed for different traits related to heat tolerance. Results showed that the genotypes G24, G10, G01, G13, G16, G25 and G14 ranked as better category considering maximum number of traits in mean performance indicating their tolerance to heat stress under late sowing condition. Phenotypic variances (σg2) of all traits were greater than those of genotypic variances (σg2). The same trends were also found in their co-efficient of variances. The phenotypic co-efficient of variances (PCV) of all traits were greater compare to those of genotypic co-efficient of variances (GCV) and their values were closer to each other.

Yield and Fruit Quality of Tomato as Influenced by Calcium and Mulching in Rooftop Cultivation

引用

Agricultural Sciences 2019年第7期10卷 893-902页

作者： Md. Abul Kalam Azad Mohammad Shafiqul Islam Md. Isrfil Hossen touria el-jaoual eaton Department of Crop Science and Technology Rajshahi University Rajshahi Bangladesh Cooperative Extension and Research Lincoln University of Missouri Jefferson MO USA

The experiment conducted in containers known as pot placed on rooftop of a building using noncalcareous grey terrace soil was carried out from October, 2012 to March, 2013 at Kazla, Motihar, Rajshahi, Bangladesh to investigate the influences of calcium and mulching practices on yield and fruit quality of tomato. The study was laid out in a split-split plot design with three replications. The trials comprised three factors: 1) three tomato varieties viz, BARI F1Tomato-5, BARI F1Tomato-6 and BARI F1Tomato-7;2) four levels of calcium (Ca) treatment (40 ppm, 60 ppm, 80 ppm, 120 ppm) and 3) mulching practices. Results of the experiment revealed that fresh yield of tomato was significantly increased by applying mulching practices due to conservation of soil moisture by mulches and therefore, reduced Ca-deficiency symptoms. The highest number of fruits per plant and fresh yield were obtained from the variety BARI F1Tomato-5. The same trend of yield and yield contributing parameters were likely to be better by using T3?treatment (80 ppm) than those of other treatments. In contrast, BARI F1Tomato-7 variety in control treatment without mulching practice gave poor quality and yield of tomato. Results suggested that BARI F1Tomato-5 variety receiving 80 ppm calcium treatment with mulching condition exposed better quality, yield and yield contributing characters of tomato. However, the T3?treatment (80 ppm) with mulching would be recommended as the best combination to grow BARI F1Tomato-5 for the farmers in Bangladesh.

Nur-Alam Siddquie Department of Crop Science and Technology Faculty of Agriculture Rajshahi University Rajshahi Bangladesh Cooperative Extension and Research Lincoln University of Missouri Jefferson City USA Senior Scientific Officer Bangladesh Agricultural Research Institute Shyampur Rajshahi

The research work was undertaken to identify the extent of genetic diversity in different parameters of wheat related to heat tolerance mechanism. Performances of currently available 25 spring wheat genotypes were studied at the Regional Wheat Research Institute, Shyampur, Rajshahi during the winter season of 2016/2017. All these genotypes (25) were grouped into five clusters on the basis of non-hierarchical clustering parameters viz. cluster I (G2, G5, G6, G16, G20), II (G4, G7, G9, G11, G12, G17), III (G10, G24), IV (G1, G13, G19, G21) and V (G3, G8, G14, G15, G18, G22, G23, G25). These groups were arranged into five (5) pairs of clusters viz. cluster I and III;II and III;II and V;III and IV;IV and V considering their similar potentiality of different traits. Results revealed that the maximum number of genotypes (8) was found in cluster V while cluster III comprised minimum genotypes (2). The inter-cluster distance was higher than intra-cluster distances. The highest and second highest eigenvalues belonged to spike/m2 (25.23%) and spikelets/spike (20.18%) respectively, along with positive canonical values in both the vectors 1 and 2 for these two traits identified them as major traits by exposing their highest potential toward genetic divergence. Cluster III produced the highest spike/m2 (388.8), grain/spike (48.1), plant height (89.5 cm), SPAD (54.2), yield (2799 kg/ha) and biomass (7758.1 Kg/ha) with lowest heading days (64.7 days), maturity days (98.7 days), canopy temperature at vegetative stage (21.7°C) and canopy temperature at grain filling stage (22.4°C).

Different aspects of micropropagation through meristem culture for the production of virus indexed source plants, in vitro tuberization and field evaluation of the in vitro regenerated plants were studied on four commercial cultivars of potato (Solanum tuberosum L.) viz., Diamant, Cardinal, Shilbilati and Lalpakri. The investigation was conducted at Rajshahi, Bangladesh from December 2010 to March 2012 to produce virus-free potato plantlets through meristem culture, shoot multiplications with root induction as well as their acclimatization and evaluation of morphological characters and tuber yield under field condition. Shoot tips of 25 - 30 day old field-grown plants of above mentioned four cultivars were used for meristem isolation. After isolation, meristems of these varieties of potato were cultured on “M” shaped filter paper bridge in Murashige and Skoog (MS) liquid medium. Four different treatments of media formulations viz. 0.1 mg/L KIN + 0.1 mg/L GA3, 0.1 mg/L KIN + 0.5 mg/L GA3, 0.5 mg/L KIN + 0.1 mg/L GA3 and 0.5 mg/L KI

引用

Natural Science 2021年第9期13卷 381-391页

作者： Md. Abul Kalam Azad Tazuddin Ahmed touria el-jaoual eaton Md. Mukhtar Hossain Md. Kamrul Haque Edward Binod Soren Department of Crop Science & Technology Rajshahi University Rajshahi Bangladesh Cooperative Extension and Research Lincoln University of Missouri Jefferson MO USA

A wheat variety BARI Gom 26 was cultivated with an objective of evaluating the effects of macro/secondary nutrients as S and Mg, and micro nutrients as B and Zn on yield, yield contributing traits and nutrient uptake status by the crop. The field experiment was con-ducted in the “North Eastern Barind Tract Soils” at Kushadaha, Nawabganj, Dinajpur, Bangladesh from November, 2014 to March, 2015. The surface soil was clay in texture, having pH 5.61, organic matter 1.58%, total N 0.10%, available P 7.03 ppm, exchangeable K 0.11 meq/100g, available S 2.57 ppm, exchangeable Mg 0.55 meq/100g, available Zn 1.30 ppm, available B 0.08 ppm. The experiment was designed with five treatments laid out in a randomized complete block design (RCBD) with three replications. The treatments were T1: NPK (control), T2: NPK + S, T3: NPK + S + Mg, T4: NPK + S + Mg + Zn and T5: NPK + S + Mg + Zn + B. All plots of wheat received 100 kg N/ha, 30 kg P/ha and 70 kg K/ha as basal dose. The secondary and micro nutrients doses were 15 kg S/ha, 6 kg Mg/ha, 2.5 kg Zn/ha and 1.5 kg B/ha. Results revealed that the plant height, tillers/hill, 1000-grain weight, yield of grain and straw, uptake of some specific nutrients in grain and straw were signifi-cantly influenced by all the treatments, though these treatments did not show any identical effect on spike length, content of P and Mg in wheat. Significantly highest amount of 1000-grain weight, yield of grain and straw weight of wheat were obtained in applying T2 treatment that employed the addition of S with recommended dose of NPK. Significant positive effects were also observed for the rest parameters in receiving the treatments composed of secondary and micronutrients (T3, T4, and T5). The highest concentration of nutrient uptake N, P, K and S in grain and straw of wheat were also obtained due to the application of T2 treatment. In the case of Mg, the maximum uptake was recorded in T4 where Mg was added as a component of this treatment. In contrast
