EFFECT OF TREE SEAWED EXTRACTS APPLICATION ON GROWTH AND YIELD OF KIDNEY BEAN (Phoseolus vulgaris L .)

Abstract

An experiment was conducted at vegetable crops farm of plant production Department ,Technical Instiute of Mosul during spring season of 2010 to study the effect of seed soaking , plant spraying , and seed soaking with plant spraying with three seaweed extracts (Hypertonik , Marvel and Algaren) 1 ml/ L . conc . on growth and yield of kidney bean plants .The experiment included ten treatments conducted in RCBD with three replicats . The results showed that applaying seaweed Algaren with 1 ml/ L . conc . by the three methods (seed soaking , plants spraying and seed soaking with plants spraying) increased significantly vegetative growth and yield characteristic and the treatment of seed soaking with plant spraying was gave the highest plant length (48.21 cm),leaf area (960.3 cm2 .) , chlorophyll content (38.52 SPAD unit ), dry weight (49.52 gm .) ,early flowering (53.01 day) . number of pods per plant (27.82 pads), pod weight (4.98 gm .) plant yield (102.62 gm .) and total yield per donum (1831 kg .) . Also applying marvel extract increased significantly plant length , leaf area , chlorophyll content , early flowering , number of pods per plant , pod weight , plant yield and total yield compared with control treatment .
