    EFFECT OF FERTILIZER MANAGEMENT AND MULCHING ON THE GROWTH AND YIELD OF LETTUCE
    (Sher-e-Bangla Agricultural University Research System, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, 2007-07) Ali, M. A.; Farooque, M. A.; Akand, M. H.; Solaiman, A. H. M.
    The experiment consisted of four levels of fertilizers and manure treatments viz. control, Cowdung 23.14 t/ha, chemical fertilizer (Urea 352 kglha, TSP 180 kglha and MP 158 kglha) and organic + inorganic fertilizer(cowdung 11.5 t/ha, Urea 177 kglha, TSP 62 kglha and MP 63 kglha) and four different mulching treatments viz., no mulch, rice straw, water hyacinth and black polythene mulch. Organic + inorganic fertilizer treatment gave maximum plant height (27.40 ern) and maximum number of leaves (24.6) per plant at 50 DAT during period of final harvesting. At the final harvest, the maximum fresh weight of leaves per plant (454.6 g), leaf area (411.5 em'), gross yield (46.01 t/ha), marketable yield (45.46 t/ha), percentage of dry matter content (11.24), percentage of fibre content (2.65) were recorded from organic + inorganic fertilizer treatement which was significantly superior to all other fertilizer treatments. Mulching treatments also showed a significant difference on plant height, number of leaf (at all dates of observation), leaf area, leaf yield per plant, percentage of fibre content, percentage of dry matter content, gross yield marketable yield per hectare at final harvest. The maximum values were in plants hight (25.61 ern), numbers of leaves (22.77), fresh leave weight (424.96 g) per plant, leaf area (393.2 crrr'), gross yield (26.01 t/ha) markatable yield (45.26 t/ha), percentage of dry matter (11.29) and percentage of fibre content (2.66) at final harvest. Different levels of organic + inorganic fertilizer as well as mulching had also significant combined effects on different parameter studied. Maximum plant height (29.13 ern), number of leaves per plant (26.00), fresh weight of leaves per plant (496.20 g), gross yield of leaves (50.27 t/ha) marketable yield (49.62 t/ha), percentage of dry matter of leaves (12.25) and percentage of fibre content (3.1) at final harvest (at 50 DAT) were observed in the treatment combination of organic + inorganic fertilizer with black polythene mulch. The best performace was obtained from treatment combination of organic + inorganic fertilizer with black polythene mulch that was considered to be the best combination of fertilizer management and mulching for maximising yield of lettuce.

    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
