Screening of different tomato varieties in saline areas of Bangladesh
M.A. Siddiky
International Journal of Agricultural Research, Innovation and Technology : IJARIT , 2012,
Abstract: A field study was conducted to screen out a number of Bangladeshi Tomato (Lycopersicon esculentum L.) varieties for salinity tolerance. Three levels of salinity were 2.0-4.0 dS m-1, 4.1-8.0 dS m-1 and 8.1-12.0 dS m-1. Significant varietal and or salinity treatment effects were registered on plant height, leaf area, plant growth, yield, dry matter plant-1, Na+ and Cl- accumulation in tomato tissues. Variety BARI Tomato 14, BARI Hybrid Tomato 5 and BARI Tomato 2 consistently showed superior biological activity at moderate salinity (4.1-8.0 dS m-1), based on dry matter biomass production thus displaying relatively greater adaptation to salinity. Under saline condition, all plant parameters of tomato varieties were reduced compared to the control except number of fruits of BARI Tomato 14, BARI Hybrid Tomato 5 and BARI Tomato 2. Thus, BARI Tomato 14, BARI Hybrid Tomato 5 and BARI Tomato 2 can be regarded as a breeding material for development of new tomato varieties for tolerance to salinity in saline areas of Bangladesh.

N. K. Halder,Md. Rafiuddin,M. A. Siddiky,R. Gomes
Pakistan Journal of Biological Sciences , 2007,
Abstract: The field study of B and Zn on Gladiolus was conducted at Floriculture Farm of HRC, Gazipur and RARS, Jessore during 2005-2006. The objective was to evaluate the response of B and Zn and to find out the optimum dose of the same for production of gladiolus. It appeared in studied data reveals that B and Zn made promising response to the growth and floral characters of gladiolus. It was also noticed in the tables that B and Zn both either in single or in combination exerted tremendous effect on the yield and quality of gladiolus. However, with subsequent addition of higher rates of B and Zn progressively increased the selective growth and flower characters to some extent and beyond the further increment of the dosage declined the results noticeably. It is also reported that gladiolus is highly responsive to chemical fertilizers. The sixteen treatment combinations included in the study noted that B and Zn at the rate of B2.0 Zn4.5 kg ha-1. along with blanket dose of N375 P150 K250 S20 kg and CD 5 t ha-1 exhibited the best performance in flower production and stretched the vase life of flower. The studied parameters like plant height (79.83 and 87.61 cm), length of spike (71.2 and 67.33 cm) length of rachis (48.86 and 45.08 cm) and leaves number (10.77 and 9.87/plant) significantly responded to the combined application of boron and zinc at the rate of B2.0 Zn4.54 as compared to other treatment combinations. Floral characters like floret number (12.85 and 12.45/spike), floret size (9.76x8.93 and 10.28x9.77 cm) and weight of stick (36.73 and 45.12 g) also significantly influenced by said treatment (B2.0 Zn4.5 kg ha-1) which was markedly differed over rest of treatments combination. Similar trend was noticed as well in single application of B and Zn with increase rates.

N.K. Halder,M. A. Hossain,M.A. Siddiky,N. Nasreen
Journal of Agronomy , 2007,
Abstract: A field trial was conducted at Calcareous Brown Floodplain Soils of Jessore Regional Agriculture Research Station during the rabi seasons of 2000-2001 and 2001-2002. The objectives were to evaluate the response of wheat varieties to different levels of Boron and to find out the optimum dose of B for maximizing yield of wheat viz protiva, Gourab and Sourav and four levels each of B (0, 1.0, 2.0 and 2.5 kg ha-1) along with a blanket dose of N120P45K80S20Zn2 kg ha-1 and cowdung 5 t ha-1 taken in the study. Results showed that variety protiva along with 2 kg B ha-1 produced significantly highest yield in both the years of study. The said treatment gave the highest mean seed yield (5.3 t ha-1) by 66% increase over the boron control (B0). In case of single effect, all the varieties tested did not contribute significantly to the yield variation. Through the variety protiva was found to be superior as compared to other two varieties. On the other hand, boron either in combination or single greatly contributed to the yield. However, the highest mean yield (4.8 t ha-1) was recorded in 2 kg B ha-1 which was significantly 45% higher over boron control. In regression analysis, a linear but quadratic relationship was also observed between grain yield and level of B. It indicated beyond that dose, the seed yield might be declined with every successive dose of B.

Journal of Agronomy , 2007,
Abstract: A field experiment was carried out at Calcareous Brown Floodplain Soil of Regional Agricultural Research Station, Jessore during the two consecutive seasons of 2000-2002. The objectives were to evaluate the effect of boron on the yield of mustard and to screen out the suitable variety (s) tested against different boron levels for maximizing yield of mustard in the study area. Four varieties of mustard viz., BARI Sharisha-6, 7, 8 and 9 and 4 levels each of boron (0, 1.0, 1.5 and 2.0 kg ha-1) along with a blanket dose of N120P35K65S20Zn5 kg ha-1 and cowdung 5 t ha-1 were taken in the study. Results revealed that BARI Sharisha-6 integrated with 1.5 kg B ha-1 was found to be superior to all other treatment combinations. The highest mean seed yield (1.96 t ha-1) was recorded with the said treatment by 25.64% yield increase. Among the 4 tested varieties of mustard, BARI Sharisha-7 showed a good performance and produced the highest mean yield (1.77 t ha-1) as compared to other varieties used. On the other hand, boron at the rate of 1.5 kg ha-1 individually increased the highest seed yield by 58.83%, over boron control (Bo). However, from regression analysis, a positive but quadratic relationship was observed between seed yield and boron levels.

Asian Journal of Plant Sciences , 2007,
Abstract: The filed study was carried out at Horticultural Research Farm, BARI, Joydebpur during two consecutive seasons of 2004-05 and 2005-06, respectively to evaluate the response of Binjal to each levels of B (0, 0.75, 1.50 and 2.25 kg ha-1) and 4 levels of Mo (0, 0.75, 1.50 and 2.25 kg ha-1) were used in the study for treatment combination. A combined blanket dose of N P K S and CD at the rate of 120:45; 100:20 kg and 5 t ha-1 were also mixed up in all the treatment plots. It is evident from both first and second year results that B and Mo either in single or in combination made significant response to the yield and yield attributes of brinjal in B-Mo deficient soil of experimental site. Boron produced significantly higher yield 76.52 t ha-1 and 26% yield increase over B control (Bo). Similarly, Molybdenum also made positive response to the yield of brinjal. All the studied parameters were significantly influenced by applied molybdenum up to 1.50 kg ha-1. However, the highest brinjal yield (82.24 t ha-1) was recorded with Mo at the rate of 1.50 kg ha-1 and beyond that the yield declined steadily. The 88% yield increase was also noticed in the same treatment. Interaction effect of B and Mo was found to be highly responsive to the yield and yield components of brinjal. However, the highest yield (91.67 t ha-1) was recorded with B-Mo combination at the rate of B1.50 Mo1.50 kg ha-1 and 166% yield increase over B-Mo control (B0 Mo0) treatment in 2nd year due to well management practices and favorable agro-climatic condition compared to the first year result.

Asian Journal of Plant Sciences , 2007,
Abstract: A field study was conducted at Brown Hill Soils (Eutrochrepts) of South Eastern Hilly region at Hill Tracts Agricultural Research Station, Ramgarh, Khagrachari during the Kharif seasons of 2004-2005 and 2005-2006, respectively. The objective was to evaluate the response of ginger (cv. local) to B and Zn fertilization and to find out the optimum dose of Zn and B for maximizing yield of ginger in Hilly Region. Four levels of B (0.1, 2 and 3 kg ha-1) and Zn (0, 1.5, 3.0 and 4.5 kg ha-1) along with combined blanket dose of N180 P50 K120 S20 and CD5 t ha-1 were taken in the experiment to study. It is evident from studied data revealed that Zn either in single or in combination with B made significant effect on ginger production in micronutrient deficient soils. However boron produced 46.72% higher yield in first year and 89.92% higher yield in second year over boron control (Bo) whole calculated 23.72 and 52.26% higher yield than that of Zinc in two consecutive years. The integrated effect of B and Zn was found to be highly significant and markedly influenced the rhizome yields and other yield attributes of ginger. The boron (3 kg ha-1) and zinc (4.5 kg ha-1) individually produced rhizome yield 23.5 and 25.8 t h-1 and 20.4 and 22.3 t ha-1 in three consecutive years of 2004-2005 and 2005-2006, respectively. However, integration of Zn and B at the maximum level (B3.0 Mo4.5 kg ha-1) significantly produced the highest ginger yield (25.5 and 26.8 t ha-1) and 125 and 143% yield increase over Boron-Zinc control (Bo Zno) in two successive years of study. Similarly, the highest net economic return Tk.7, 52.030 and Tk. 804000 and the highest marginal rate of return (MRR) 484 and 548%, respectively were obtained with the application of B at the rate of 3 kg ha-1 and Zn at the rate of 4.5 kg ha-1 which was found to be economically profitable for ginger production in South-Eastern Hilly region.

Asian Journal of Plant Sciences , 2007,
Abstract: A field study on mustard was conducted in Non-Calcareous Dark Grey Floodplain Soil (AEZ-1) at Rajbari, Dinajpur during the rabi seasons of 2000-2001 and 2001-2002. The objectives were to find out the optimum dose of boron and to evaluate a suitable variety for maximizing the yield of mustard. Four varieties viz., BARI Sarisha-6, BARI Sarisha-7, BARI Sarisha-8 and BARI Sarisha 9 integrated with four levels each of boron (0, 1.0, 1.5 and 2.0 kg ha-1) along with a blanket dose of N120 P35 K65 S20 Zn5 kg ha-1 and cowdung at the rate of 5 t ha-1 were tested in the study. The interaction effect of variety and boron had a significant response on the yield components of mustard. The highest seed yield (2.23 t ha-1) was recorded in BARI Sarisha-6 with 2 kg B ha-1 in the second year (2001-2002), while in the first year (2000-2001), the recorded yield was 1.51 t ha-1 which was statistically significant over the boron control (B0). However, the highest mean seed yield (1.87 t ha-1) was obtained from the same treatment combination by 35.5% yield increase in both the years of study. Though the individual effect of boron and variety were found to be more pronounced than interaction. Here, BARI Sharisha-6 and 2 kg B ha-1 separately augmented highest seed yields of mustard (1.91 and 1.98 t ha-1) for both the years of study when a blanket dose of other fertilizers were ensured. In regression analysis, the linear relationship between seed yield and the levels of boron was observed in the mean seed yield of two consecutive years of study. It meant beyond the level, the seed yield might be declined due to the toxic effect of excess dosage of boron.

Journal of Biological Sciences , 2007,
Abstract: The field study of Zn and B on the yield of turmeric was carried out at Brown Hill Soils (Eutrochrepts) of South Eastra Hilly region of at Hill Tracts Agricultural Research Station, Ramgarh, Khagrachari during the Kharif seasons of 2001-2005 and 2005-2006, respectively. The objective was to evaluate the response of turmeric to Zn and B fertilization. Four levels of B (0, 1, 2 and 3 kg ha-1) and 4 levels of Zn (0, 1.5, 3.0 and 4.5 kg ha-1) oxide were included in the study. A combined blanket dose of N130P35K8S20 kg and CD 5 t ha-1 were also mixed in all the treatment plots. It was evident from two years study that both Zn and B either in single or in combination had significant effect on the growth and yield attributes of turmeric in Zn-B deficient soil at experimental site. Boron produced approximately 11.0 and 18.19% higher yield than Zinc in both the years. However, the highest turmeric yield (21.4 and 25.5 t ha-1) was recorded with the maximum B level (B3.0 kg ha-1) which was 79.58% higher over B control (B0). While Zn produced 28.57 and 66.43% higher yield compared to Zn control (Zn0) treatment. However, the integrated effect of Zn and B was und to be highly responsive and markedly dominated the turmeric yield and their yield attributes. The highest rhizome (turmeric) yield (27.5 and 28.9 t ha-1) was recorded with the combination of Zn and B at the rate of 4.5 and 3.0 kg ha-1 and 170% higher yield over Zn-B control treatment (Zn0B0) in 2nd year and 145% in first year. It was also revealed from the economic analysis that same Zn-B combination gave the highest gross margin Tk. 422704 and Maximum Rate of Return 1557% (MRR) which was economically profitable r turmeric production in hilly region.
Laparoscopic plication of the linea alba as a repair for diastasis recti – a mesh free approach
A.H Siddiky,C.R Kapadia
Journal of Surgical Case Reports , 2010,
Abstract: Diastasis recti is a common occurrence in multiparous women (1), caused by repeated stretching of the abdominal wall by the gravid uterus. A small proportion of patients have a persisting weakness which may be symptomatic and present to the surgeon. We would like to present a case which, thus far, has had a successful outcome from laparoscopic plication of the linea alba without mesh. The benefits of this approach are as for any laparoscopic versus open technique, most notably improved recovery time, reduced pain and wound infection. Furthermore, avoidance of a mesh negates the risks associated with insertion of a foreign body.

Saudi Medical Journal , 2012,
Abstract: Objective: To investigate the possible role of radiate ligament in idiopathic scoliosis. Methods: This study was designed as a case-control study adapted to cadavers. Eighteen human cadavers, 12 males and 6 females of Caucasian race, with a mean age of 55 years were studied at the Department of Anatomy, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia from November 2010 to February 2012. Among the studied subjects, 15 were with normal spines, and 3 were scoliotic. The upper and lower bands of radiate ligaments were identified and measured. All cadavers were examined grossly. Scoliotic cadavers were also examined radiologically. Results: The present study revealed that the mean of the lengths of the upper bands of radiate ligaments, on the concave side, in each scoliotic cadaver showed a highly significant shortening compared with that of the upper bands of the corresponding segments in cadavers with normal spines, while no significant change was detected when comparing those of the lower bands to normal values. Conclusion: The study suggested a possible relationship between radiate ligament shortening and the etiology of idiopathic scoliosis.
