The current study was carried out using data of the Nucleus Herd and Community Herd of Red Chittagong Cattle (RCC) established through USDA funded Red Chittagong Cattle project under the Department of Animal Breeding and Genetics, BAU, Mymensingh. Data on 151 calves and 75 lactating cows were analyzed. The estimated heritability values were 0.45 ± 0.05 for birth weight, 0.48 ± 0.05 for weaning weight, 0.41 ± 0.08 for pre-weaning daily gain, 0.47 ± 0.06 for lactation length, 0.43 ± 0.07 for lactation milk yield and 0.35 ± 0.09 for average daily milk yield. The highest Breeding Value (BV) were for birth weight (3.2 kg), weaning weight (24.46 kg), pre-weaning daily gain (82.39g), lactation length (52.25 days), lactation milk yield (186.04 kg) and average daily milk yield (0.66 kg). The minimum and maximum phenotypic index values by using phenotypic parameters were for growth traits (1196.24 and 4713.24) and milk production traits (8573.93 and 40670.81). The minimum and maximum genetic index values by using breeding values were for growth traits (1812.49 and 2870.21) and milk production traits (-1812.49 and 2870.21). All the estimated index values can be used in animal selection and breeding programs for RCC improvement and similar index selection can be applied for other indigenous cattle development programs in Bangladesh or elsewhere.

Potato cultivars grown in Bangladesh have low levels of general resistance to late blight. As such, most commercial potato farmers rely on fungicide applications for control of Phytophthora infestans, the causal agent of late blight. Management of late blight of potato requires an integrated approach that includes rotation with non-hosts, resistant cultivars, cultural practices, and fungicides. The study on efficacy of some new fungicides against late blight disease of potato was conducted at ARS, Alamnagar Rangpur during rabi season 2010-2011 to select suitable fungicides against late blight of potato. Thirteen different fungicides were tested and all the tested fungicides showed significantly better performance over control. Considering percentage disease incidence T4,T6 and T12 showed better performance than all other treatment. In case of T4,T6 and T12 treatment disease reduction was more than 80 % over control. Significantly the highest tuber yield 25.5 t ha-1was obtained from T3  which was statistically similar to the yield of T2,T5 , T6, T9, T10, T11and T12  treatment whereas the lowest tuber  yield 14.5 t ha-1 was obtained from control treatment. Field experiment was conducted from 2010 to 2011 to investigate the comparative efficacy of the fungicides. In the field, applications of fungicide that preceded the largest incremental increase in disease incidence provided the best control of disease or increased yield.Progressive Agriculture 26 (2): 103-108, 2015

Abstract:The experiment was conducted in medium highland at Dacope, Khulna during rabi season of 2010-11. The aim of the study was to observe the effect of integrated use of bio-slurry along with inorganic fertilizer on the performance of water melon grown in AEZ 13. The experiment was laid out in a randomized complete block design with four replications. Three fertilizer doses viz. T 1 : Soil test based inorganic fertilizer dose for high yield goal (HYG), T 2 : Cowdung bio-slurry @ 5t/ha + IPNS basis inorganic fertilizer dose for high yield goal and T 3 : Farmers' practice (average of 20 farmers surveyed) were taken as treatment. Results showed that yield and yield contributing characters of water melon were significantly influenced by the treatments. The highest fruit yield (44.50 t/ha) was recorded in cowdung bio-slurry@ 5 t/ha + IPNS basis inorganic fertilizer dose (T 2 ) followed by T 1 (40.27 t/ha). The lowest yield (35.20 t/ha) was obtained from farmers' practice. Economic analysis also revealed that the gross return (Tk. 534000.00/ha) and gross margin (Tk. 427515.00/ha) were higher in T 2 . Benefit-cost ratio (BCR) was also higher in T 2 (5.01).
