Effect Assessment of Kelpak Sl on the Bean Yield (Phaseolus Vulgaris L.)

Abstract

Biostimulators applied in the cultivation of plants stimulate the processes of life and increase their hardiness to stress conditions, contributing to greater and better quality of yield. One of them is Kelpak SL obtained from brown seaweed species Ecklonia maxima. The aim of experiment carried out was to assess a potential effect of Kelpak SL on bean (Phaseolus vulgaris L.) cultivar Aura yield. The trial was carried out during 2010-2011 years on the experimental field of Institute of Agricultural Sciences The State School of Higher Education in Chełm. Treatments with Kelpak were carried out in 2 different concentrations (0.2 % and 0.4%) and in two application frequencies (one application in the 2-3 leaves stage or two applicationsfirst in the 2-3 leaves stage and second at the beginning of the bean's blooming). Received results were compared with the control where Kelpak was not applied. The number and the weight of seeds, the number of pods and the weight of thousand seeds per 1 m 2 were recorded. The beneficial effect of seaweed extract of Ecklonia maxima on the yield of beans (Phaseolus vulgaris L.) was demonstrated. The highest number and weight of seeds and number of pods were obtainment in the combination of once application with 0.2 % solution of Kelpak SL in 2010 and once application with 0.4 % solution of Kelpak SL in 2011. Application of Kelpak SL significantly increased number and weight of seeds and number of pods compared with the control where Kelpak SL was not applied.

Effects of seaweed extract on yield and protein content of two common bean (Phaseolus vulgaris L.) cultivars

“…The improved bean yield observed in this research is confirmed by numerous studies concerning the effect of seaweed extracts on the yield of various crops. In the case of legumes, Ecklonia maxima extract was found to have a positive effect on white bean (Phaseolus vulgaris L.) yield (Kocira et al, 2013). Although the present study, in which a significant increase in the number and weight of grains as well as in the number of pods were obtained after Kelpak SL application, confirms the above observation, the response of the cultivars was shown to depend on biostimulant concentration.…”

“…The use of Ecklonia maxima extract, which contains natural PGRs, in growing crops beneficially affects their growth and yield, in particular under biotic and abiotic stress conditions (Papenfus et al, 2012;Stirk et al, 2014;Rengasamy et al, 2015a). This is confirmed by numerous studies conducted on horticultural and agricultural crops (Ambika and Sujatha, 2016;Calvo et al, 2014;Kavitha et al 2008;Kocira et al, 2013;Saravanan et al 2003 (Kavipriya et al, 2011;Kumar and Sahoo, 2011;Latique et al, 2013;Rathore et al, 2009;Raverkar et al, 2016;Thirumaran et al, 2009;Zodape et al, 2010). Nevertheless, to date only few studies have confirmed the positive effect of using seaweed extracts on the chemical composition of crops (Latique et al, 2013;Raverkar et al, 2016;Sosnowski et al, 2015).…”

“…Ecklonia maxima extract (Kelpak SL) is a biostimulant which is environment-friendly and safe and which contributes to improve yield and quality of many crop plants (Calvo et al 2014;Kocira et al, 2013;Kocira et al, 2016;Sosnowski et al, 2015). As shown in the study by Rengasamy et al (2015b), the positive effect ofKelpakon plants is probably associated with eckol (phlorotannin) contained in it, which possibly acts through the synergistic effects with other plant growth hormones.…”

Organic seaweed nano powder effect on growth and yield attributes of pigeonpea

“…Cytokinins in vegetative plant organs are associated with nutrient partitioning; whereas in reproductive organs, high levels of cytokinins may be linked with nutrient mobilization. This was conformity with Kocira et al (2013) in bean and Sugnathi (2014) in sunflower. 1% concentration of Caulerpa racemosa has proved increase in yield, growth and biochemical content in Vigna mungo (Abhilash et al, 2013).…”

Evaluation of germination capacity and selected biometric parameters (length and dry weight of roots and coleoptile) of sunflower seeds (Helianthus annuus) after application of preparations containing effective microorganisms (EM)

“…Among the most important biopreparations containing algae Bio-Algeen 90 and Kelpak SL should be mentioned, based on humic acids -Humiplant and Rosahumus and on effective microorganisms (EM) i.e. EM-1, EM-4 (Augustynowicz, et al, 2008;Boligłowa and Gleń, 2008;Ertekin, 2011;Grzesik, et al, 2012;Javaid and Bajwa, 2011;Klama, et al, 2010;Kocira, et al, 2013;Matysiak, et al, 2012;Naqvi, et al, 2000).…”
