“…The availability of Fe ions, and other elements such as N, K, Ca, Mn, Zn, for enhancing the plant photosynthetic activity, and the leaf chlorophyll content and color (Netto et al, 2005;Dordas and Sioulas, 2008) has been claimed by several authors using commercial and non commercial products in the cultivation of several plant species, such as tomato (Sánchez Sánchez et al, 2009Siminis et al, 1998, onion seedlings (Bettoni et al, 2014), cowpea (Neri et al, 2002a), and chrysanthemum plants (Fan et al, 2014). Other authors have reported data showing the close relationship between leaf chlorophyll content, and plant growth and yield (Enriquez et al, 2004;Ciganda et al, 2009).…”

Soluble bio-based substances (SBS) isolated from municipal biowastes and a commercial Leonarditebased product were applied as substrate drench or as foliar spray to grow the ornamental hybrid Euphorbia x lomi. The SBS were found more powerful than the commercial Leonardite product in enhancing plant photosynthesis, growth and aesthetic effect, improving flower quality, and optimizing water use efficiency. Enhancement factors of plant performance indicators by SBS ranged from 1.3 to 8.6 relatively to the control plants, and from 1.2 to 4.5 relatively to plants treated with the commercial Leonardite product at equal applied dose. The environmental and economic implication of these results for agriculture, the management of urban wastes, and the chemical industry are discussed.

“…Plants with a high leaf chlorophyll content would be expected to have enhanced photosynthesis and hence enhanced ability to form carbohydrates. Many studies have reported that increased chlorophyll concentrations in plant leaves, achieved by improved nutrition, are correlated with higher yields in agricultural and horticultural crops (Wood et al 1992;Kararurt et al 2009;Fan et al 2014). It is possible that a beneficial Trichoderma-crop association results in growth enhancement of the plants via promotion of photosynthesis as indicated by the high chlorophyll content and leaf area observed in Tri-1 and Tr-2 treatments.…”

Suada IK. 2017. Short Communication: The potential of various indigenous Trichoderma spp. to suppress Plasmodiophora brassicae, the pathogen of clubroot disease on cabbage. Biodiversitas 18: 1424-1429. On the island of Bali, cabbage (Brassica oleracea L.) is a vegetable that has high economic value especially for farmers who cultivate it as a cash crop. However, the clubroot disease caused by the microbial pathogen Plasmodiophora brassicae decreases its productivity. Much effort has been expended in attempts to decrease the pathogen attack by use of synthetic fungicides, however, this has not had much success; more over such pesticide applications generate environmental pollution. Therefore, biological control using Trichoderma or other organisms antagonistic to the pathogen is an attractive alternative. The purpose of this study was to find, isolate and identify Trichoderma spp. able to decrease the disease incidence and increase plant growth. Twelve indigenous Trichoderma isolates were tested on cabbage plants grown in polybags containing local soil media culture treated with the Trichoderma inocula at a concentration of 1.5x106 CFU per polybag. The results showed that three Trichoderma isolates, i.e. T. hamatum-1, T. harzianum-1, and T. harzianum-2, were able to decrease the clubroot disease and increase cabbage growth as well.

“…The seaweed extracts used as biostimulants in grapevine increased the chlorophyll content, yields and berry weight (Sabir et al 2014). Fan et al (2014) described that the foliar application of humic acid improved the leaf area, net photosynthesis rate and the chlorophyll content in chrysanthemum compared with those of control plants. Regarding the results obtained Data presented as mean ± standard deviation.…”

Foliar sprays with humic acid derived from vermicompost at a concentration of 50 ml•L-1 induced a significant increase in the total leaf area, yield and total soluble solids. For several measurements performed in plants we found no significant difference between grapevines treated with HA T2 and those with HA T3. The experimental results in the present study confirm that foliar application with humic acid may improve growth, yield, and berry quality attributes of grapevine.
