“…For example, Zareabyaneh and Bayatvarkeshi (2015) have already shown that the use of SRFs can help mitigate nitrate loss by up to 36% (Zareabyaneh and Bayatvarkeshi 2015). However, while much is known about the proper methods of applying SRFs in many agricultural plants (e.g., ; Rahman and Zhang, 2018;Ebrahimi et al, 2019;Nielsen et al, 2019), such information is limited for economically important forest tree species.…”

We investigated the effects of different placement methods of applying slow-release fertilizer on the growth and foliar nutrients of three contrasting tree species (i.e., fast-growing Betula platyphylla and Larix kaempferi and slow-growing Chamaecyparis obtusa) to provide implications for increasing their growth and survival in marginal forest lands. We applied 84 g pot -1 of solid compound fertilizer (SCF) at different positions: no fertilization (CON), subsurface placement (SCF s ), and bottom placement [35-cm depth (SCF b )] in a greenhouse condition. Results revealed that the height and RCD (root collar diameter) of the three species had the highest growth under SCF s . Total biomass across SCF s , SCF b , and CON ordered as follows 130, 72, and 28 g seedling -1 in B. platyphylla, 89, 38, and 27 g seedling -1 in L. kaempferi, and 61, 24, and 23 g seedling -1 in C. obtusa. In contrast, SCF b resulted in the highest root length across the treatments in all species. The root biomass allocation was also higher in SCF b (28%-40%) than that of SCF s (12%-24%). SCF s had higher N uptake in all species than the other treatments. In conclusion, SCF s has shown to be the most effective placement method of SCF application for increasing aboveground biomass and nutrient (N) acquisition, while SCF b was the placement effective for increasing root length and root biomass growth in all species. These results are relevant to the promotion of ecofriendly and cost-effective fertilization approach of increasing growth and survival of economically important forest tree species, especially in steep slope and erosion-prone areas or marginal forest lands.

“…The positive effects of organic fertilizers on the qualitative and quantitative characteristics of different plants have been emphasized in many studies (Lakhdar et al, 2011;D'Hose et al, 2014;Ebrahimi et al, 2019). It was reported that organic fertilizers increased activity of microorganisms in soil (Arancon et al, 2004) and improved soil physiochemical and biological properties, increased nutrient storage capacity (Arancon et al, 2005) and slow release of nutrients.…”

“…Cattle manure at low levels of plant density signi cantly increased dry ower yield probably through increased nitrogen release in soil (Motta and Maggiore, 2013). Some studies have shown that the application of organic fertilizers reduce the salinity effects and increase the uptake of phosphorus and nitrogen thus improve the qualitative and quantitative characteristics of plants (Sabahi et al, 2010;Ebrahimi et al, 2019). In a study, the effects of different levels of vermicompost (0, 5, 10, 15 and 20 t ha − 1 ) on the qualitative and quantitative characteristics of German chamomile (Matricaria chemmomilla) were investigated.…”

“…Organic fertilizers appear to be likely to increase the ower number per plant by supplying the plant with the micro nutrients (Motta and Maggiore, 2013). Organic fertilizers might enhance number of owers through improving soil microbial activities (Padmavathiamma et al, 2008;Ebrahimi et al, 2019), increasing water holding capacity (Shamsodin et al, 2007) and supplying more essential nutrients (Motta and Maggiore, 2013), increased photosynthesis and plant dry matter (Atiyeh et al, 2002;Ebrahimi et al, 2019), which eventually led to increased owering. The effects of different organic and biological fertilizers on the sa ower were studied and it was reported that vermicompost solely or combined with Nitroxin® and Nitrajin® biofertilizers improved the quality and quantity of the plant (Rezvani Moghaddam et al, 2013).…”

“…It was reported the application of organic fertilizers, especially vermicompost, on Calendula o cinalis L. resulted in a signi cant increase in the number of branches per plant and the ower number per plant (Rezaee and Baradaran, 2011). It was reported that application of vermicompost increased dry matter of tomato (Lycopersicum esculentum L.) also improved nitrogen uptake e ciency in organic tomato production (Ebrahimi et al, 2019).…”

Background: Employing of advanced statistical methods to quantify agricultural information has helped to carry out targeted planning to alleviate the problems of farmers, researchers and policy section. One of these exploratory methods, is multivariate statistical analysis that examines and models the relationship between variables. Considering the importance of Echium amoenum and its use growing trend in traditional medicine and the pharmaceutical industry, also the lack of information on the correlations between its yield and morpho physiological traits, the objective of this study was to determine the causality path in which the Echium amoenum characteristics affects the yield of Echium amoenum as regards of application of organic and chemical fertilizers under different plant densities.Results: The employed method revealed that organic fertilizers increased flower yield compared with the control. The flower yield as a result of application of compost, vermicompost and cattle manure were increased by 25, 28, and 27 percent compared with the control, respectively. The results of multiple regression showed that variables of plant height, shoot dry weight, flower number per plant were the main factors affected the flower yield. The relative contribution of shoot dry weight was 16 and 25 percent more than plant height and flower number per plant, respectively. Conclusions: Causality analysis identified that shoot dry weight per plant had indirect effect on flower yield in different paths, as mainly was imposed through plant height considering the path coefficients. this study suggests that optimum production of Echium amoenum with application of ecological inputs along with effective agronomical managements of the causal paths of flower yield forming, including increase in shoot yield and plant height could be achieved through an ecological cropping system with reduced costs and no health concerning due to agrochemicals residual.

Nitrogen accumulation and partitioning in field‐grown heirloom tomato cultivar Brandywine

Heirloom tomato (Solanum lycopersicum L.) are a high-value crop for organic vegetable growers. Tomato plants have a high N requirement and are adversely affected by insufficient, excessive, and poorly timed N fertilization. However, little information is available about N dynamics in heirloom tomato and whether their nutritional needs differ from those of hybrid fresh-market (HFM) tomato. The project's goals were to (a) develop seasonal N accumulation curves for the popular heirloom tomato cultivar Brandywine, (b) measure the N removed with the harvested fruits, and (c) determine whether N concentrations from recently matured leaves from adequately and underfertilized fields as well as N accumulation and partitioning fell within published thresholds for HFM tomato plants. We tracked the leaf N concentrations, growth, yields and N accumulation of organically grown Brandywine tomato in a 2-yr replicated field trial under low-and high-N availability treatments. We also collected leaf and fruit samples from fertilized and unfertilized plots on local commercial organic fields. Total N accumulation ranged between 25 to 45 g N per linear bed meter and did not differ with N treatment. The N removed with the harvested fruit averaged 1.14 kg Mg −1 fresh fruit across all sites and years and differed by site but not N fertility. On average, 70-80% of tomato N demand occurred between full bloom and early harvest. The observed N accumulation per unit yield, seasonal N accumulation pattern, and leaf sufficiency thresholds for Brandywine tomato were within the ranges published for HFM tomato varieties. INTRODUCTIONHeirloom tomato (Solanum lycopersicum, L.) can be one of the most profitable crops for California organic vegetable growers, but they also are expensive to grow and are subject to stringent aesthetic quality standards. Tomato yields and quality are known to be affected by the amount and timing of N fertilization (Scholberg, McNeal, Jones, et al.
