“…This agrees with the known inhibitory effects of cytokinins on root growth in wheat and other plants (Stenlid, 1982). However, while Kelpak contains the natural cytokinin zeatin and its derivatives (Featonby-Smith and van Staden, 1983;Finnie and van Staden, 1985;Nelson, 1985), the growth regulator used in this study was the synthetic cytokinin BA. As the metabolism ofzeatin can be different to BA and other synthetic cytokinins (Letham and Palni, 1983) it is difficult to exclude completely the possibility that the cytokinins in Kelpak were in some way affecting the wheat.…”

“…Although artificial cytokinins may be more cost-ly to apply to wheat crops than fertilizers, inexpensive seaweed concentrates and extracts contain relatively high concentrations of natural cytokinins (Featonby-Smith and van Staden, 1983;1984a, b;Finnie and van Staden 1985;Tay et al, 1985;. Furthermore, studies on barley and wheat have shown that early applications of seaweed concentrates can increase spikelet number and yield (Featonby-Smith and van Staden, 1987;Nelson and van Staden, 1986).…”

The effects of the seaweed concentrate 'Kelpak' on the growth and yield of wheat grown under conditions of varying K supply were investigated. Kelpak had no significant effect on the yield of wheat receiving an adequate K supply, but significantly increased the yield of K stressed plants. The increase in yield was caused by an increase in both grain number and individual grain weight. Although the beneficial effects of seaweed concentrates have often been attributed to their cytokinin content, several lines of evidence suggested that this group of plant growth regulators may not be solely responsible for the observed effects of Kelpak on wheat. Irrespective of the physiological mechanism of action, Kelpak would appear to have considerable potential for increasing yield in K stressed wheat and may therefore reduce the requirement of wheat for K fertilization.

“…increased crop yield and plant vigor to withstand adverse environmental effects (Featonby-Smith & Van Staden, 1983). Significant increase in the yield of crops due to foliar application of seaweed extracts has been reported in the literature (Aurthur et al, 2003;Zodape et al, 2008;Rathore et al, 2009).…”

The effect of seaweed liquid fertilizer (SLF) of Sargassum myriocystum on germination, growth and biochemical constituents of Vigna mungo was studied. Different concentrations (5%, 10%, 25%, 50% and 75%) of SLF were prepared using distilled water. A total of 100 seeds were soaked for each SLF concentration for a 24-h period and were later placed in various Petri plates and watered regularly. Water-soaked seeds were used as controls. Resumen Utilización de extractos del alga Sargassum myriocystum como estimulante de plántulas de Vigna mungo (L.) HepperSe estudió el efecto de un fertilizante líquido de algas marinas (SLF) preparado con Sargassum myriocystum sobre la germinación, crecimiento y componentes bioquímicos de Vigna mungo. Se introdujeron 100 semillas durante 24 h en diferentes concentraciones (5%, 10%, 25%, 50% y 75%) de SLF (en agua el control), se colocaron en placas de Petri y se regaron con regularidad. La germinación fue del 98% para las semillas introducidas en SLF al 10%. La longitud de los brotes (21,13 cm plántula -1 ), longitud de la raíz (12,19 cm plántula -1 ), peso fresco y peso seco (3,910 y 0,320 g plántula -1), clorofila (0,547 mg g -1 peso fresco) y contenido en carotenoides (0,359 mg g -1 peso fresco) fueron las mayores en esta concentración. Adicionalmente, esta concentración produjo el mayor contenido de proteínas (1,898 y 1,508 mg g -1 peso fresco), aminoácidos (0,370 y 0,306 mg g -1 peso fresco), azúcares reductores (6,031 y 3,448 mg g -1 peso fresco), azúcares totales (8,414 y 7,055 mg g -1 peso fresco), actividad α-amilasa (1,403 y 1,380 μg min -1 mg -1 proteína) y actividad β-amilasa (1,099 y 1,029 μg min -1 mg -1 proteína) de brotes y raíces, respectivamente. Por tanto, el SLF produjo una mejor respuesta a bajas concentraciones, mientras que con concentraciones más altas se obtuvo una respuesta decreciente.Palabras clave adicionales: biofertilizantes; fertilizantes líquidos de algas marinas; lenteja negra.

“…They contain all major and minor plant nutrients including bio-control properties; they also contain organic compounds such as auxins, gibberellins and precursors of ethylene and betaine that impact plant growth [7]. Beneficial effects from the use of seaweed extracts as natural regulators have induced increased crop yield and plant vigor to withstand adverse environmental effects [8]. Bean (Phaseolus vulgaris L) is a major food legume and an important source of protein in many countries.…”
