EFFECT OF FERTILIZERS AND IRRIGATION ON GROWTH AND YIELD OF KOHLRABI (Pages : 28 - 43)

An experiment was carried out at the Horticulture Farm, Bangladesh Agricultural University, Mymensingh, during the period from November, 2005 to February, 2006 to investigate the effects of irrigation and fertilizer on growth and yield of Kohlrabi. The experiment consisted of three levels of irrigation at an interval of 7, 14 and 21 days and six fertilizer treatments namely (i) cowdung @ 15 t/ha, (ii) poultry manure @ 9.4 t/ha, (iii) Urea-TSP-MOP @ 326-218-201 kg/ha, (iv) Urea-TSP-MOP-Gypsum @ 326-218-201-55.6 kg/ha, (v) Urea-TSP-MOP-Gypsum-Borax @ 326-218-201-55.6-9.52 kg/ha and (vi) Urea-TSP-MOP-Gypsum-Borax-Zinc Sulphate @ 326-218-201-55.6-9.52-20 kg/ha and was laid down in split plot design with three replications. The plants irrigated at 7-day intervals produced the highest (43.59 t/ha) marketable yield while the lowest (16.80 t/ha) yield was recorded in the treatment of irrigation at 21- day intervals. The highest yield of kohlrabi (35.43 t/ha) was obtained from treatment of Urea-TSP-MOP-Gypsum-Borax-Zinc Sulphate @ 326-218-201-55.6-9.52-20 kg/ha and minimum yield (21.20 t) were found when cowdung @ 15 t/ha was applied. The highest yield per hectare (51.48 t) was obtained from irrigation at 7-day intervals with Urea-TSP-MOP-Gypsum-Borax-Zinc Sulphate @ 326-218-201-55.6- 9.52-20 kg/ha fertilizers. Download
