    ECO-FRIENDL Y MANAGEMENT OF SHOOT AND FRUIT BORER (Earias vittella FAB.) USING BOTANICALS AND BIO-CONTROL AGENT
    (Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2011-07) Afroz, R.; Rahman, M. M.; Ali, M. R.
    A study was conducted at the Sher-e-Bangla Agricultural University, Bangladesh during May 2011 10 August 20 II to evaluate the effectiveness of botanicals and parasitoid for the management of okra shoot and fruit borer (Earias vittella Fab.). The experiment was laid out in a Randomized Complete Block Design (RCBD) comprising eight treatments viz., TI ; Neem oil @ 4mlll of water sprayed at 7 days interval, T2; Neem seed kernel extract @50 g/l of water sprayed at 7 days interval, TJ; Neem leaf extract @ 200gll of water at 7 days interval, T. ; Trichogramma evanescens @ 0.5g1plot at 7 days interval, T, ; Trichogramma evanescens @ 0.25g1plot at + neem oil @ 4mlll of water sprayed at 7 days interval, T6 ; Trichogramma evanescens @ 0.25g1plot + neem seed kernel extract @ 50gll sprayed at 7 days interval, T7; Trichogramma evanescells @ 0.25g1plot + neem leaf extract @ 200gll of water at 7 days interval, Ts ; Untreated control. Among the treatments T, (Spraying of neem oil @ 4mlll of water + release of Trichogramma evanescens egg parasitoid @ 0.25g1plot at 7 days interval) performed the best in terms of percent reduction of shoot infestation (96.50), flower bud infestation (83.33%) and fruit infestation by weight (86.90%).

    GROWTH AND YIELD OF LETTUCE (Lactuca sativa L.) AS INFLUENCED BY POTASSIUM
    (Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2009-07) Akand, M. H.; Shaha, M. K.; Afroz, R.; Rahman, M. A.; Ali, M. A.
    Two factorial Randomized Complete Block Design experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka-I 207, during the period from November 2006 to March 2007 to study the effect of different levels of potassium viz: no potassium (KII), 120 kg K,Olha (K ,), 130 kg K10lha (K1) and 140 kg K10 Iha (K.1)on the growth and yield of lenuce. The experiment was conducted with seven replications. Application of different doses of potassium showed significant differences among yield and different yield contributing characters. The highest plant height (21.08 em), number of leaves (26.4 I), leaf length (23.29 ern), leaf breadth (22.04 em), fresh weight of plant (325.82 g), dry matter content (12.32%) and yield (27.14 t/ha) were recorded from 130 kg K,Olha (K,) and control treatment gave the lowest results
