Effect of tendu (Diospyros melanoxylon RoxB.) leaf vermicompost on growth and yield of French bean (Phaseolus vulgaris L.)

Abstract

Background Tendu (Diospyros melanoxylon RoxB.) leaf is widely used in India in the form of wrapper for making a crude smoking stick popularly known as ''Beedi''. Solapur city of Maharashtra state has large number of small beedi making units. Large quantity waste from these industries in the form of trimmed leaf residues is available as feed material for preparation of vermicompost. The present investigations were aimed to study effect of vermicompost prepared from such novel leaf residues as the tendu leaves on the growth and yield of Phaseolus vulgaris under greenhouse conditions. The seeds of French bean were sown in cement pots containing soil alone (control), soil with various concentrations of vermicompost alone, soil with various concentrations of urea only and different admixtures of vermicompost and urea. Results The study revealed that the seed germination, shoot and root length, shoot and root fresh weights, shoot and root dry weights, thousand grain weight and grain weight per plant increased significantly (p B 0.05) compared to control due to application of vermicompost when used at proper proportions. Thus, the growth and yield parameters were significantly (p B 0.05) greater in T 2 (75 % N through vermicompost) than in T 1 (100 % N through vermicompost) and T 3 (50 % N through vermicompost). Many growth parameters of T 1 were lower than those in the control indicating some deleterious effect of vermicompost at higher concentrations. The combined application of tendu leaf vermicompost and urea increased the growth and yield of Phaseolus vulgaris significantly (p B 0.05). The maximum grain yield was due to combined application of vermicompost at 25 % N through vermicompost plus 75 % N through urea. Conclusions The pot trial experiments suggested that the quantity of chemical fertilizer for French bean could be reduced by 25-50 % due to combined application of vermicompost and chemical fertilizer. However, application of tendu leaf vermicompost alone at higher concentrations may reduce growth parameters and yield of P. vulgaris.

Cultivable bacterial diversity and early plant growth promotion by the traditional organic formulations prepared using organic waste materials

“…This might be due to the presence of plant growth inhibitors, acidic pH (5.6) and nutrients in undiluted 100 % PG. In line with this, Kadam and Pathade (2014) also showed the negative effect of higher concentration of vermicompost application on French bean growth compared to lower concentration of compost application. There were no consistent positive results for plant growth improvement on dilution of original organic formulations, except for 100 % PG.…”

Effects of Solid and Liquid Vermicompost Application on Bean Growth and Common Bacterial Blight Disease in Different Growth Medium

“…In contrast, Zaller (2006) could not determine an effect of foliar application of aqueous vermicompost extracts to different tomato varieties under field conditions, in terms of plant growth and nutrient content. On the other hand, thorough vermicompost studies were found to show increase in fresh and dry weight of the Chard (Aksu et al, 2017), Bean (Kadam and Pathade, 2014) and Lettuce (Adiloğlu et al, 2018) and improvement of yield and clorophyll content in for lettuce (Kibar, 2018). In general, it is seen that Vermicompost forms may exhibit different effects according to plant type, application method and target.…”

The Effect of Vermicompost Enriched with Ulva Lactuca on Germination of Cucumber Seeds

“…Among these, stimulated seed germination in various plant species such as mung beans (Karmegam et al 1999), tomato plants (Atiyeh et al 2000b;Zaller 2007), petunia (Arancon et al 2008) and pine trees (Lazcano et al, 2010a) kg/da applications with 93.3%. In another study, lettuce, pea, wheat, tomato, cabbage and radish plants and ornamental plants were first germinated in small pots containing vermicompost obtained from animal wastes, and then they were surprised (Edwards et al 1988).…”
