EFFECT OF BORON AND ZINC FERTILIZATION ON CORM AND CORMEL PRODUCTION OF GLADIOLUS IN GREY TERRACE SOILS OF BANGLADESH (Pages : 85 - 89)

Field trial of corm and cormel production of gladiolus was carried out at Floriculture field of Horticulture Research Centre, BARI, Gazipur during rabi seasons of 2005-2006 and 2006-2007, respectively. The objectives were to evaluate the response of B and Zn on corm and cormel production and to find out the optimum dose of B and Zn for maximizing yield of bulbs for Gladiolus cultivation. Treatments comprising each four levels of B (0, 1, 2 and 3.0 kg/ha) and four levels of Zn (0, 1.5, 3.0 and 4.5 kg/ha) along with blanket dose of N375, P150, K250, S20 and CD 5 t/ha were used in the study. It was felt in the study that B-Zn integration contributed more than their single applications. The interaction effects of B and Zn @ B2.0, and Zn4.5 kg/ha significantly contributed to the yield of individual corm weight (26.07 g and 27.58 g) and number of cormels (9.78 and 14.43) and weight of cormels/plant (31.94 g and 51.67g) than other B-Zn combination along with control (B0Zn0). Single application of B and Zn also contributed to the yield parameters but their response was not pronounced as their integration performed. Download
