ON-FARM EVALUATION THROUGH MODERN AND TRADITIONAL CULTIVATION PRACTICES OF POTATO PRODUCTION. Tabassum N, Haque MM, Bir MSH, Zaman MK and Shaha M

ABSTRACT

 The study was carried out using modern inputs against traditional inputs and practices for potato production were conducted in the different agro-ecological zones and agro-climatic locations of Bangladesh during 2011-2012. The selected study areas were brought under potato production with the different modern varieties of potato like Diamant (55%), Cardinal (30%), and Granola (15%). It was observed that the total cost of potato production (fixed cost and variable cost) varied from Tk. 132,180 to Tk. 148,735 per ha for modern to traditional cultivation practices. The major cost involvement for modern practices was observed in (a) seed (43.1%), (b) hired and family human labors (19.93%), (c) fertilizer (16.23%), and (d) pesticides (5.26%). And for traditional practices of potato the cost involvement was found (i) seed (46.46%), (ii) fertilizer (21.66%), (iii) hired and family human labors (10%) and (iv) pesticides (9.9%). The cost was comparatively low in modern practices than in traditional practices as it was found mainly due to adoption of recommended technology, appropriate dose and timely use of modern inputs and practices. The yield was found 26 t ha-1 in modern practices and 24 t/ha in traditional practices. The net profit was significantly higher in modern practices than traditional practices; the net profit in modern practices was found at Rangpur Tk. 98,079 per ha, Thakurgaon Tk. 72,741 per ha and Comilla Tk. 46,950 per ha. It was recommended from the study that the farmers will be economically benefited if they use modern inputs; adopt technologies; use quality seed of improved varieties at recommended dose; timely use of fertilizers and pesticides; timely application of irrigation; and appropriate crop management including weeding and other practices.

IMPACT OF YEAR ROUND VEGETABLE PRODUCTION MODEL (SAYEDPUR MODEL) IN RANGPUR REGION. Anwar MM, Khatun MUS, Ferdous MZ and Islam MK

ABSTRACT

 The study was conducted at the FSRD site, Lahirirhat, Rangpur and MLT site, Ulipur, Kurigram to assess the impact of homestead vegetable production model (Sayedpur model). A total of 60 farmers, 30 from FSRD site Lahirirhat, Rangpur and 30 from MLT site, Ulipur, Kurigram were selected as a sample of the study. Data were collected during April-May 2013. On an average, sample farmer produced 510 kg and 332 kg vegetables in 2013 using homestead vegetable production model at Lahirirhat and Ulipur, respectively whereas it was 96 kg and 78 kg in the above sites during 2007 and 2009, respectively. Gross margin was 448% higher in 2013 compared to 2007 Lahirirhat, Rangpur. Again, gross margin was 350% higher in 2013 compared to 2009 at Ulipur, Kurigram. The level of adoption for vegetable production on house roof, trellis and back yard were more than 60 percent in the both sites. Probit model showed that age of the farmers had negative influence on adoption of homestead vegetables production model. Contrary, farmers training, number of effective female labour and extension contact had positive influence on adoption that means probability of adoption of homestead vegetable production model would increase with the increase number of effective female labour, farmers training and extension contact. The change of socio economic parameters showed 20 to 70% for moderate change and 20 to 60% for average change. Non-availability of vegetables seed at sowing time and lack of technical knowledge were their main problems for homestead vegetable production.

EFFECTS OF DIFFERENT SOURCES OF PHOSPHORUS ON THE GROWTH AND YIELD OF BRRI DHAN29. Robbani MG, Hoque MA, Huda A, Bir MSH, Haque MM and Uddin MJ

ABSTRACT

 An experiment was carried out at Mymensingh during the period from February to June 2011 to study the effects of different sources of phosphorus on the growth and yield of BRRI dhan29. The experiment was designed with six treatments and laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatment combinations were T0: control (No P), T1: 100% P from Triple super phosphate (TSP), T2: 100% P from Di-ammonium phosphate (DAP), T3: 100% P from compost, T4: 50% P from TSP + 50% P from compost T5: 50% P from DAP + 50% P from compost. All the plots received P from different sources @ 25 kg/ha except control. Application of different sources of P resulted in a significant increase in yield contributing characters of BRRI dhan29. The effect of DAP was more pronounced than that of TSP or compost. Application of P also significantly increased the grain and straw yields of rice. The highest grain (5.19 ha-1) and straw (7.11 t/ha) yields were observed by the addition of P from DAP while the lowest grain (3.95 t/ha) and straw (4.20 t/ha) yields were observed in control treatment where no P fertilizers were added. Results also indicate that application of DAP caused a remarkable increase in grain and straw yields of rice. Application of P from different sources led to an increase in NPKS contents and uptake by rice. In most cases, DAP resulted in a higher nutrient uptake by rice crop. DAP can be used as a better source of P fertilizer compared to TSP or compost for rice cultivation in Bangladesh.

ABSTRACT

The experiment was conducted at the MLT (Multi Location Testing) site, Gobindogonj, Gaibandha to observe the performance of BARI released aroid varieties (BARI Panikachu1, BARI Panikachu2, BARI Panikachu3 and local)  in the two consecutive kharif seasons (2010-11 to 2011-12). Among the tested varieties, BARI Panikachu1 gave the highest stolen yield (22.73 and 23.75 t/ha during two consecutive years) which differed significantly from other varieties. The lowest stolen yield (10.81 and 12.81 t/ha) was recorded from local variety in two successive years. In case of rhizome yield, the highest yield was found from BARI Panikachu3 (22.94 and 23.98 t/ha) and the lowest (13.26 and 13.69 t/ha) was obtained from local variety during two successive years. Similarly, the highest gross return (Tk. 309440 and 323840  per ha) and gross margin (Tk. 144440 and 166260 per ha) were obtained from BARI Panikachu1 whereas, those items were the lowest from local variety in two successive years.

EFFECT OF BIOCHAR, POULTRY LITTER, COWDUNG AND VERMINCOMPOST ON YIELD OF LENTIL. Hadiuzamman Mohammad, Mia Shamim, Ahmed Sultan, Abuyusuf M and Biswas Purnendu

ABSTRACT

Biochar amendment to soil considered to be sustainable technology as it increases crop yield along with Corban sequestration. Biochar can be produced many different ways resulting variable qualities. Biochar production using low cost technologies is one of the important issues to be addressed for its extension in developing countries. A low cost biochar stove has been developed and biochar has been produced. To validate stove derived biochar’s effectivity, an experiment was conducted in compared to three organic manures i.e. poultry litter, cowdung and vermin-compost in two variety i.e. BARImusu4 and BARimusur7. BARImusur7 yielded higher (seed yield 920.80 kg/ha) than BARImusur4 (seed yield 900.40 kg/ha). Among the organic matter amendment, biochar resulted in similar yield (1060 kg/ha) in comparison to vermin-compost (972 kg/ha) and poultry litter treatment (988 kg/ha). However, it was higher than cowdung (689 kg/ha) Biochar in combination with BARImusur7 provided the best yield (1120 kg/ha). The higher yield might be manifested due to higher water regime and biological nitrogen fixation in the biochar amended plot.

EFFECT OF WEED CONTROL ON THE YIELD AND YIELD COMPONENTS OF JUTE. Alam MS, Chowdhury AKMSH, Islam MR, Zaman F, Hoshain S and Islam MS

ABSTRACT

 The experiment was conducted at Mymensingh from March to August, 2011 to find out the effect of jute species, weed control method and their interaction on the fibre yield and yield components of jute. The experiment comprised of two species viz., i) Deshi jute (Corchorus capsularis): CVL-1 (V1) ii) Tosha jute (Corchorus olitorious): O-9897 (V2) and six weeding regimes viz., i) no weeding (W0), ii) One weeding on 15 day after sowing (W1), iii) Two weeding on 15 and 30 DAS (W2) iv) Three weeding on 15, 30 and 45 DAS (W3) v) Whip super 9 EC @750 ml/ha on 15 DAS (W4) and vi) Whip super 9 EC @750 ml/ha on 15 DAS and one weeding on 30 DAS (W5). The experiment was laid out in a randomized complete block design (RCBD) with three replications. Results revealed that variety had significant effect on all the characters under study. Deshi jute (CVL-1) showed significantly higher values over the Tosha jute Corchorus olitorious (O-9897) except the plant height. Highest fiber yield was obtained from Deshi jute (1.686 t/ha) while Tosha jute contributed the yield of 1.37 t/ha. The fiber yield was recorded 1.93 t/ha at three weeding followed by 1.72 t/ha in case of two weeding treatments. Deshi jute (CVL-1) with three weeding produced better fiber yield (2.11 t/ha) followed by two weeding in combination with Deshi jute (CVL-1). The lowest fiber yield (0.95 t/ha) was produced by Tosha jute (O-9897) with no weeding treatment. Results suggested that Deshi jute (CVL-1) along with three weeding will be the best possible combination for obtaining maximum fiber yield of jute.

INTERACTION EFFECT OF WATER MANAGEMENT AND DIFFERENT LEVELS OF ARSENIC CONTAMINATION ON BRRI DHAN29. Rana S, Ahmmed S, Debnath MR, Biswas SK and Haque SMA

ABSTRACT

The experiment was carried to study the effects of different water management practices on growth, yield and arsenic content of BRRIdhan29 at different levels of soil added arsenic. Total As content of the soil was 22.5 µg/g. Three levels of As viz. 0, 10 and 20 µg/g (on soil basis) were added to soil. The source of As was Na2HAsO4.7H2O (sodium arsenate).  Three water management practices viz. continuous standing water, water saturated condition and alternate wetting-drying condition were imposed to the rice plants growing in pots after 14 days of transplanting. Thus there were 9 treatment combinations viz. As0 × saturation condition, As0 x continuous standing water, As0 × alternate wetting-drying, As10 × saturation condition, As10 × continuous standing water, As10 x alternate wetting-drying, As20× saturation condition, As20 × continuous standing water, and As20 × alternate wetting-drying. The interaction effects of different levels of As and water management practices were significant regarding number of total tillers per pot, plant height, panicle length, filled grains per panicle, 1000-grain weight, grain and straw yields and As concentrations in rice grain and straw. The grain yields obtained under different water management practices from control pots which was much higher compared to the As treated pots. The highest grain yield was obtained under alternate wetting-drying condition in As control pots. There was no grain formation under saturated soil condition with 20 µg/g As added pots. Arsenic toxicity to rice was reduced when grown under alternate-wetting drying condition compared to other two methods of water management. The toxicity was more when plants were grown under moisture saturated condition. When BRRI dhan29 plants were grown with 10 µg/g As added condition, all the three water management practices produced statistically different grain yields. Alternate wetting-drying and continuous standing water practices with 20 µg/g added As produced identical grain yields but such yield was much lower compared to those observed in As control pots.

EFFECTS OF DIFFERENT LEVELS OF ARSENIC CONTAMINATION ON BRRI DHAN29. Rana S, Islam MR, Ahmmed S, Miah MAM and Haque SMA

ABSTRACT

A experiment was conducted in a net-house at Mymensingh to study the effects of different water management practices on growth, yield of BRRI dhan29. Total As (Arsenic) content of the soil was 22.5µg/g. Three levels of As viz. 0, 10 and 20 µg/g (on soil basis) were added to soil. The source of As was Na2HAsO4.7H2O (sodium arsenate). The different rates of As application significantly decreased yield and yield contributing characters of BRRI dhan29. On the other hand As concentrations of grain and straw increased significantly due to added As to soil. The rice straw had much higher As concentration than the rice grain. There was significant variation in grain As and straw concentrations among the water management practices at a particular level of As level. Alternate wetting-drying practice of water management showed the lowest grain As concentration compared to other management practices at all levels of As addition to soil. Grain As concentration ranged from 0.37 µg/g when plants were grown without any As addition under alternate wetting-drying condition to 1.52 µg/g in soil treated with 20 µg/g As and under continuous standing water condition. The straw As concentration ranged from 3.66 µg/g obtained from alternate wetting-drying condition in As control pot to 13.5 µg/g in continuous standing water condition with 20pm As addition.
