Ecological benefits associated with plant growth-promoting rhizobacteria (PGPR) inoculants offer a promising integrated nutrient management option to counteract plant nitrogen (N) deficiency. We performed field experiments to evaluate the effect of integrated N fertilizer regime involving chemical N fertilizer (CNF) and N-enriched compost (NEC), either alone or combined with selected PGPR (Pseudomonas aeruginosa) on sunflower seed quality, N use efficiency (NUE) and soil fertility during 2014-2015. We found that integrated N biofertilizer application resulted in significantly higher seed oil concentration, fatty acid composition, and harvest index in both cropping years. Greater effects on N yield efficiency (NYE), N use efficiency (NUE), N physiological efficiency (NPE), and photosynthetic N use efficiency (PNUE) were recorded in nitrogen-enriched compost+PGPR inoculant (NECPI) treatment followed by chemical N fertili-zer+PGPR inoculant (CNFPI) treatment. Statistically significant differences were observed in linoleic and linolenic acid, NYE, and NUE for treatment year interaction, thus, suggesting that the integrated N biofertilizer approach facilitates the efficient N use by sunflower for improving yield and seed quality. Moreover, we also found considerable enhancement of soil N fertility after two consecutive cropping years of sunflower. The enhancement of seed quality, N use efficiencies, and soil N fertility through integrated N biofertilizer application emphasizes the importance of balanced crop N nutrition, ensuring sufficient N supply to sunflower with adequate N balance in soil for the next crop. Overall, combination of PGPR with NEC amendment may optimize N uptake efficiency and reduce N fertilizer losses, which is necessarily required for the sustainable sunflower production.

“…Such a significant correlation resulted from the significant increase in response to growing EC that resulted in both an increased number of corms above 25 mm and uptake of specific nutrients, following the order K 2 O > P 2 O 5 > CaO > N > MgO. Specific indications on the existing relationship between corm size and use efficiency of specific nutrients (e.g., N and P) were recently provided [39]. Accordingly, this shall be considered when designing a fertilization plan specifically targeting the production of reproductive corms.…”

Defining Optimal Strength of the Nutrient Solution for Soilless Cultivation of Saffron in the Mediterranean

Saffron is traditionally cultivated in soil as a semi-perennial crop, although the feasibility of crop production is today constrained in Europe due to both agronomic and socioeconomic factors. Accordingly, interest has been increasing concerning its possible cultivation within protected environments through adoption of soilless cultivation technologies. The aim of the present study was to optimize nutrient solution features in the soilless cultivation of saffron corms. The trial was conducted in a greenhouse at Almeria University. Saffron was grown in 15-L pots filled with perlite. Three fertigation treatments were used, obtained by a linear increase of all nutrients of one standard in order to reach an electrical conductivity (EC) of 2.0 (control, EC2.0), 2.5 (EC2.5) and 3.0 (EC3.0) dS·m−1. Measurements included determinations of shoot length, corm yield, as well as nutrient uptake from the nutrient solution and concentrations within plant tissues. The nutrient solution with the highest EC (EC3.0) allowed obtaining three to five times more corms above 25-mm diameter. The increasing EC had a significant effect on the increase of macronutrient uptake, except for NO3− and NH4+ and resulted in a general increase of nutrient concentrations in tissues, such as corms and roots. Both macronutrient uptake and accumulation in plant tissues were highest under EC3.0. Nutrient uptake was significantly correlated with production of larger corms due to higher horizontal diameter.

“…Nitrogen is one of the main chemical elements required for plant growth and photosynthesis (Cechin and de Fatima Fumis, 2004;Salvagiotti et al, 2009), therefore plays a major role in achieving the maximum economic yield of saffron (Chaji et al, 2013;Kirmani et al, 2014;Koocheki and Seyyedi, 2015). In addition, by considering the particular role of phosphorous in cell division, ATP generation, chlorophyll synthesis (Schachtman et al, 1998) and plant reproductive growth (White and Veneklaas, 2012), as well as saffron yield improvement (Naghdi Badi et al, 2011), study on phosphorus and nitrogen uptake is essential to better understand the changes in corm yield of saffron.…”

A greenhouse research experiment was conducted. The experiment was arranged in factorial layout based on a completely randomized design. The mother corm size (0.1 vermicompost 10 t levels (foliar application and no application) were assigned as the first Based on the results, with increasing mother corm size, formation of small corms (0.1 medium (4.1 applied. Moreover, foliar application increased daughter corm yield in medium and larger size corms. Phosphorus and nitrogen concentration in daughter corms increased with increasing the size of mother corm phosphorus and nitrogen conc on account of cattle manure application improve corm number than rather corm weight.
