EFFECTS OF DRIP IRRIGATION AND MINERAL FERTILIZATION ON YIELD AND ANATOMY OF DWARF BEAN
Field experiments were conducted in 2000-2001 on sandy soil to assess the influence of micro-irrigation and various doses of mineral fertilizer on some anatomical features of dwarf bean. Irrigation caused an increase of colenchyma thickness, also of mesophyll diameter of the biggest vascular bundle, but decreased the layer of sclerenchyma in bean stalk. Similar effects were found as result of fertilization: increased thickness of epidermis with cuticula, mesophyll, sclerenchyma and diameter of the stalk. Leaves of irrigated bean were thicker, and the diameter of the biggest mesophyll cell was larger. As result of high doses of fertilizer the leaves developed larger vascular bundles, longer stomatal cells, and thicker colenchyma and sclerenchyma. Neither irrigation nor fertilization affected noticeably the anatomy of bean pods. The yield of dwarf bean seeds increased as result of irrigation and mineral fertilizer by 6% and 40% respectively. The largest crop from irrigated plots was obtained under the influence of 360 kgha1, whereas for the not irrigated plots the dose of 240 kg NPK proved best.
