(HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR., 2009-07) RAHMAN, MD. MIZANUR; Prof. Dr. Md. Mamunur Rashid
An investigation was carried out at Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of 2008-09 to explore the possibility of controlling Alternaria blight of mustard caused by Alternaria brassicae and A. brassicicola. A promising mustard variety BARI-9 was used in this investigation. A total of eight management practices viz., aqueous radish root extract (1:1), aqueous radish root extract (1:2), petroleum ether radish root extract (1:1), petroleum ether radish root extract (1:2), BAU-Biofungicide(0.2%), Iprodione2 spary (0.25%)and Iprodione-3 (0.25%)spary including a control (plain water spray) were applied as foliar spray. The Alternaria symptom wass appeared on lower leaves at 27-days old plants and spraying were started from the time of disease initiation with 7 to 14-day interval. Among the treatments, Iprodione-3-spray showed superior performance in controlling Alternaria blight of mustard. Iprodione-3 spray reduced leaf area diseased, siliqua area diseased, percent plant infection, percent leaf infection, percent siliqua infection and number of spot per siliqua by 69.92%, 66.41%, 35.08%, 65.17%, 80.13% and 57.23%, respectively and increased seed yield by 55.68% over control. The second best performance against Alternaria blight was obtained from Iprodione-2 spray. Radish root extracts was sprayed with 7-day interval. Other than Iprodione, petroleum ether radish root extract (1:1) performed best in controlling the disease. Spray of petroleum ether radish root extract (1:1) reduced leaf area diseased, siliqua area diseased, percent plant infection, percent leaf infection, percent siliqua infection and number of spot per siliqua by 34.87%, 44.39%, 20.07%, 27.33%, 34.07% and 39.13%, respectively and increased seed yield by 35.93% over control. BAU-Biofungicide was sprayed twice with 14-day intervals and also showed significant result next to radish root petroleum ether extract (1:1) and increased seed yield by 25.64% over control. Regarding the economic consideration, iprodione-2 spray gave the maximum return (BCR=3.57) while the control treatment showed the lowest return (BCR=0.82). Petroleum ether radish root extract (1:1) as eco-friendly management practice exhibited good performance next to Iprodione (BCR=1.96). In laboratory investigation with Thin Layer Chromatography (TLC) of petroleum ether radish root extract towards antifungal compounds showed one distinct compound and mixture of compounds. The distinct compound showed high Ry value indicate non-polar type. Therefore, it may be concluded that Alternaria blight of mustard can be controlled with petroleum ether radish root extract (1:1) as foliar spray reducing maximum disease incidence and providing satisfactory higher seed yield in the sense of environmental pathology.

(Department of Agricultural Botany, 2008-12) RAHMAN, MD. MIZANUR
A pot experiment was conducted at the Iangladesh InsLitute ol Nuclear ALricutture. Mvrnensingh, during September to November 2007 to investigate flower production, tiowering pattern, reproductive eliieienev. yield attributes and their relationship with seed yield in 10 munghean genotypes. The experiment was laid out in a Completely Randomized Design with Ibur replications. High yielding genotypes produced greater number ol opened flowers (range 34.2-45.0 plani1 ) having longer flowering duration (range 15-I8 days) than the low yielding ones. In contrast, low, yielding genotypes produced fewer opened flowers (range 16.1-2] .0 Plant) and also .4   showed shorter flowering duration (range II - IS days) except M13-46 (21 days). I ugh yielding genotypes had higher flower production rate over time than the low yielding ones and maximum flower production occurred within 10-12 days after flowering started. 1-lowever. high yielding genotypes had inferior performance in reproductive eliieicncy (range 52.6-61 .4Q/0) than in low yielding ones (59.5-812%) indicating that there Was a scope of increasing yield by improving the reproductive efficiency in high yielding genotypes in rnungbean. Iligh yielding genotypes maintained increased teal area. TDM. increased flowers and pod numbers plani'. In contrast, low yielding genotypes produced shorter and narrower plant canopy, tower flowers and pods plani'. Seed yield had highly significant and positive correlation with pod number (r = 0.89**) and pod number depended on leaf area (r = 0.75**), TDM (r = 0.84**). raceme (r 0.76*) and flower number (r 0.87*t). Genotypes ML3-l7 and ?v113-35 showed better perlormance in respect of growth, reproductive, yield and yield contributing characters.
