(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2014-07) Islam, M. S.; Noman, A. A.; Bhuiyarr, M. S. R.
An investigation was performed for assessment of genotype-environment interaction and stability of the 10 promising genotypes of Chilli on plant height, root length, individual fruit weight, fresh weight of shoot, oven dry weight of shoot and fruit yield per plant with ten promising chilli (Capsicum frutescens L.) genotypes. The experiment was laid out in randomized complete block design with three replications and four environments. The combined analysis of variance showed that the mean sum of square due to Genotype (G), Environment (E) and G x E interaction were significant for all the characters studied here suggesting presence of significant variation among the genotypes and environments. The additive main effects and multiplicative interaction (AMMI) biplot for yield clearly indicated that Env-3 (Urea + TSP + MOP + Boric Acid) and Env-4 (only Cow dung) were poor and Env-I (Urea + TSP + MOP + Gypsum+ ZnO) and Env-2 (Urea + TSP + MOP + Cow dung) were found to be rich and favourable due to high inputs for chilli production. Where, Env-2 (Urea + TSP + MOP + Cow dung) was found highly favourable for chilli production. The stable genotypes found were BD-2059 and Bogura Jatt, exhibited moderate mean yield and could be adopted for general cultivation. Kalo Dhawna morich, Bogurar Lomba Morich and Bullet exhibited comparatively higher mean yield but were unstable across the environments and can be recommended to cultivate in rich environments.

The experiment was conducted during October, 2009 to March 2010 at the Horticulture Research Farm of Sher-e-Bangla Agricultural University, Sher-e Bangia Nagar, Dhaka to determine the response of organic manure on yield, quality and economic benefit of broccoli. The experiment included 16 treatments with 4 levels of cowdung manure (0, 10, 20 and 30 tlha) and 4 levels of mustard oil cake (0, 300, 400 and 500 kg/ha) were used to study the effect of these on broccoli production. All treatments showed significant influence on days to curd initiation, primary curd diameter, stem diameter, primary curd weight, number of secondary curds per plant, weight of secondary curds. dry matter content of curd. curd yield but it did not show any significant effect on chlorophyll a and b content in leaves. moisture(%), protein (%) ascorbic acid content of curd. The maximum curd yield per hectare (15.27 tlha) were found from the C2M2 (20 tlha cowdung + 400 kg/ha mustard oil cake) treatment and the minimum curd yield (8.07 tlha) was obtained from the control.

(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2014-07) Jahan, M. S.; Akhter, R.; Aftabijjaman, M.; Sarker, M. A. W.; Beg, M. A. H.
Elevated level of groundwater arsenic (As) in Bangladesh has resulted as a massive calamity of exposing a large population to health risk and affecting livelihood and sustainable development of the country. The extensive use of arsenic contaminated groundwater in irrigation poses a potentially long term detrimental effect to human health as well as it is an environmental hazard. Arsenic is spreading in various ways in the environment and creating various hazards. This study was performed to detect the level of arsenic concentration in animal feed chain. Grass and Water hyacinth samples of two commonly used animal feeds were collected from arsenic contaminated areas of Faridpur district. After collection, the samples were prepared by a series of steps such as, washing, drying and digestion; finally arsenic was determined by atomic absorption spectophotometric method. For this purpose the FJ-HG-AAS (Flow Injection Hydride Generator Atomic Absorption Spectophotometer) method was used. The arsenic absorbed by the animal feed (grass and water hyacinth) samples was determined. The mean arsenic concentration in Grass and Water hyacinth were 0.397±()'o75 ppm (n=20) and 0.365±O.035 ppm (n=20), respectively. In this study it was found that the level of arsenic both in Grass and Water hyacinth is greater than that of the maximum permissible level in drinking water (0.05 ppm, WHO). This study was performed to detect the level of arsenic in animal feed of As contaminated area of Faridpur district.
PROFITABILITY ANALYSIS OF HYV BORO RICE UNDER DIFFERENT TENURE SYSTEMS IN JHENAIDAH DISTRICT OF BANGLADESH
(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2014-07) Pervin, L.; Yasmin, F.; Begum, R.; Rahman, R.
An attempt has been made in this study to examine the profitability of Boro rice producing farms according to these three tenure groups such as owner, cash tenant and crop share tenant farmers. About 90 sample farmers, 30 owner farmers, 30 cash tenant farmers and 30 crop share tenant farmers were selected for the present study. The field survey was conducted over the period from July-September, 2014. The average gross returns per hectare were Tk. 108933.00, Tk. 119079.50 and Tk. 117368.48 in owner, cash tenant and crop share tenant farmers respectively. Gross return was higher of cash tenant farmer than other farmer but the total cost of production was higher in owner farmer and cash tenant farmer so their net return is lower than crop share tenant farmer. It was observed that per hectare net return was Tk. 14296.78. 27285.54 and 38615.72 for the owner. cash tenant and crop share tenant farmers respectively. Which indicates that crop share tenant farmer earned more profit than the other farmers.

(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2014-07) Alam, M. J.; Beg, M. A. H.; Hossain, M. M.
Moringa (Moringa oleifera Lam. moringaceae) is a highly valued plant that is mostly cultivated in the tropics and subtropics. It is used for food, medication and industrial purposes. The objective of the study was to assess the nutritional value of Moringa leaves and to determine the effect of supplementing Moringa oleifera leaves (MOL) on growth performance, carcass and non-carcass characteristics of Black bengal goats. The dried leaves had crude protein levels of 30.3%. Thedried leaves had the following mineral contents: calcium (3.65%), phoshorus (0.3%), magnesium (0.5%), potassium (1.5%), sodium (0.164%), sulphur (0.63%), zinc (13.03 mglkg), copper (8.25%), manganese (86.8 mglkg), iron (490 mglkg) and selenium (363 mg/kg). The fiber content was neutral detergent fibre (NDF) (11.4%), acid detergent fibre (ADF) (8.49%), acid detergent lignin (ADL) (1.8%) and (acid detergent cellulose (ADC) (4.01 %). The condensed tannins had a value of 3.2%, while total polyphenols were 2.02%. In the other hand, a total of 36 castrated goats aged 8 months, with a mean initial weight of 7.63±O.8 kg, were randomly divided into three diet groups with twelve goats in each. The duration of the trial was 90 days. All goats received a basal diet of grass ad libitum and mixed basal diet (200 g/day each). The MOL groups were fed additional lOOg (MOLl) and 200 g (MOLZ) of dried M. aleifera leaves, respectively. The third group (Control) did not receive any additional ration. The attained average daily weight gain for goats fed MOLl, MOL2 and Con were 103.3, 101.3 and 43.3 g, respectively (p<0.05). Higher (P<0.05) feed intakes observed were in MOL2 (491.5 g) and MOLl (490.75 g) compared with Con (404.5 g). The hot carcass weight was higher (p<0.05) for MOL2 (7.18 kg) and MOLl (7.14 kg) than for the Con group (5.46 kg). The dressing percentage in MOL2 (50.8%) and MOLl (50.0%) were higher (P<0.05) than that of the Con (44.9%). The growth performance and carcass characteristics of MOL2 and MOll goats were not different. Moreover the experimental result reveal that MOL has a cholesterol lowering effect and no lesion has been identified in the gastrointestinal mucosa of the parasitized animals fed on MOL mixed diet. Feeding MOL improved the growth performance and carcass characteristics of goats in an almost similar way, which indicates that M. oleifera could be used as a supplement or additives in goats.
