“…Concerning p and k percentages, it observed that T 4 (50% inorganic N plus 50% compost and algae) significantly increased P% and K%(0.149, 0.159) and (1.31,1.38) than all other treatments in both studied seasons, respectively. The abovementioned results were in accordance with those obtained by Tatini, et al(1991) Saleh, et al (2006), Eman et al (2008), ElKhawaga (2012), Farouk etal. (2014 and Faissal etal.…”

During 2015 and 2016 seasons, Thompson Seedless grapevines were fertilized with organic fertilizer, compost, humic acid and bio fertilizer (Ascophyliumnodosum) algae. These fertilizers were used as a partial replacement for inorganic N fertilizer improving yield, lowering pollution and enhancing the efficiency of exportation to foreign markets. The obtained results indicated that application of N as 50% inorganic N plus50% organic N and algae 5ml / vine was the best management system for ensuring the best yield, number of clusters /vine and cluster weight, leaf mineral content and improving the chemical characteristics of berries as total soluble solids (TSS), total acidity (TA) and Tss /acid ratio and decreasing nitrate and nitrite content in the berries.

“…Enhanced root growth parameters can be attributed to the presence of humic acid in vermicompost and vermiwash. Humic acids have been known to enhance root growth (Tallini et al 1991) and nutrient uptake by increasing the root cell membrane permeability (Valdrighi et al 1996).…”

Purpose To study the organic production in two varieties of Linum (Linseed) crop using different proportions of vermicomposts and combination of vermiwash as an environment friendly substitute to chemical fertilizers for organic farming of Linseed. Method Vermicompost prepared from cattle dung was mixed in different proportions, i.e. 0, 20, 40, 60, 80, and 100% vermicompost v/v with soil and commercial potting media (Perlite, Peat and Coconut coir). To study the germination, vegetative growth, reproductive growth and yield in two varieties of Linum usitassimum L. LC-54 and LC-2063 were grown in a polyhouse for a 2 years trial. A total of 960 seedlings and 240 plants were studied for assessment of result in 24 treatments. Additional treatments with foliar application of 1:1 v/v vermiwash and recommended dose of inorganic fertilizer were done to determine and compare the role of vermicompost, vermiwash and inorganic treatment. Results Substituting soil with 60% (v/v) vermicompost in LC-54 and with 40% (v/v) vermicompost in LC-2063 improved the performance of seeds, root morphology and stem growth. Life cycle of crop was shortened in two varieties of Linseed raised under different treatments of vermicompost and vermiwash. Performance of LC-54 was better at 60% and that of LC-2063 was at 40%, which can be attributed to their genotypic differences. Vermicompost proportion above 60% was of no use at any stage of life cycle in both the varieties of Linum. Germination and yield were further improved when foliar application of vermiwash was integrated with vermicompost for nutrient management when compared with recommended chemical fertilizer treatment and control. Conclusion Bio-efficacy of vermicompost and vermiwash for production of organic Linseed crop has been well established with enhanced yield.

“…(1994) have reported promoted growth and nutrients uptake of plant due to the addition of HA. The plants take more mineral elements due to the better development of the root systems along with development of proliferate root hair and increasing surface area from branches and root hairs, which should increase the efficiency of the root in uptake of N,P and K (Valdrighi et al, 1996) In addition ,the stimulation of ion uptake in accompanied HA led many investigators to propose that these materials may affect membrane permeability (Zientara ,1983 andTattini et al,1991) . It is related to the surface activity of humic acid resulting from the presence of both hydrophilic and hydrophobic sites (Chen and Schnitzer, 1978).…”
