In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irrigation after 60, 120 and 180 mm cumulative evaporation from pan class A) set as main plots and nitrogen rates (0, 60,120 and 180 kg N ha-1) set as sub plots. The results showed that increasing irrigation interval from 60 to 180 mm cumulative evaporation reduced flower number per m-2, biomass yield and plant height 65.6, 69.3 and 8.3%, respectively. Also in comparison with control, irrigation after 120 and 180 mm evaporation reduced flower dry yield 16.2 and 72%, respectively. However, the highest WUE was related to irrigation after 120 mm evaporation (0.161 and 0.788 kg m-3 for dry flower and biomass, respectively). Nitrogen fertilizer utilization significantly increased flower yield, flower number, biological yield, WUE and plant height, but there was not any significant difference between 120 and 180 kg N ha-1 treatments. Interaction of irrigation and nitrogen on all traits was not significant. Totally, the results indicated that treatment of irrigation after 120 mm evaporation with 120 kg N ha-1 application is suitable for marigold cultivation in Birjand

Five carnation cultivars (‘Grand Salam’, ‘Nelson’, ‘Kaly’, ‘Cinderella’ and ‘Tempo’) were evaluated with respect to growth, yield and quality characteristics under lath house conditions at Kala Shah Kaku Research Station, Directorate of Floriculture, Lahore during 2011. Among the cultivars studied, maximum plant height was recorded in carnation cultivar ‘Grand Salam’ (78.66 cm) closely followed by ‘Kaly’ (78.23 cm) and ‘Cinderella’ (77.96 cm). Number of shoots was highest in cultivars ‘Tempo’ (6.3) and ‘Nelson’ (6.2). Maximum stem thickness was observed in ‘Nelson’ (6.21 mm) and minimum in ‘Grand Salam’ (3.63 mm). Maximum number of internodes per stem were found in ‘Nelson’ (12.66) followed by ‘Kely’ (11.33) and ‘Grand Salam” (11.00). Highest flower yield per plant was recorded in cultivars ‘Tempo’ (6.4) and ‘Nelson’ (6.33). Maximum number of flowers per square meter were recorded in cultivar ‘Nelson’ (198.3) followed by ‘Tempo’ (189.6). Hence it can be concluded that cultivars ‘Nelson’ and ‘Tempo’ were found superior with respect to growth and flower yield characteristics under lath house conditions.

This study was conducted during 2008-2009 to investigate the influence of different organic nutrient combinations on yields and quality of strawberry cv. Kurdistan in Iran. The experiment comprised of five organic nutrient treatment combinations including the recommended dose of N, P and K through chemical fertilizer as control. Treatment N2 (manure+Azotobacter+ woodash+phosphorus solubilizing bacteria+oil cake) improvedsignificantly quality of fruit about diameter (3.11cm), length (3.95 cm), volume (20.397 cm3), weight (11.11g), total sugars (7.95%), total soluble solids (TSS) (9.01o Brix), acidity (0.857), TSS: acidity ratio) (11.12) and yields (238.95 g/plant).

In order to study on effect of plant density and nitrogen on yield and yield components of Visia faba (faba bean), the experimental design was implemented by randomized complete block with three replications at 2010- 2011 in Lahijan. The experimental factors were three plant density (25×25 cm, 35×35 cm and 45×45 cm) and four nitrogen fertilizer (0, 20, 40, 60 kg ha-1). In this experiment, features such as seed yield, weight of 100 seeds, the number of pod per plant and harvesting index were measured. The results showed that the effect of plant density and nitrogen were significant on seed yield but were not significant on weight of 100 seeds and the no. of pod per plant. The highest seed yield was obtained in 25×25 cm plant density. Also with increasing of N up to 60 kg ha-1, harvesting index increased. The interaction effect of plant density and nitrogen on seed yield was significant and 25×25 cm plant density and 40 kg ha-1 nitrogen had shown the most effective on seed yield. But the interaction effect of plant density and nitrogen on other features hadn’t significant.

To study the effect of different substrates on growth and yield of gerbera, this experiment was carried out as randomized completely block design with 14 treatments and 3 replications. Treatments were as fallowing: fine sand, peat+fine sand (25%+75%), peat+fine sand (50%+50%), perlite+peat (75%+25%), perlite+peat (50%+50%), perlite+peat (25% +75%), perlite+peat+expanded clay (25%+70%+5%), perlite+peat+ expanded clay (50 %+25%+25%), perlite+peat+expanded clay (25%+50%+25%), perlite+expanded clay (50%+50%), cocopeat, cocopeat+ perlite (75%+25%), cocopeat+perlite (50%+50%), coco peat+perlite+ expanded clay (50%+25%+25%), plants were fertilized with a same nutrient solution. Results showed that the growing medium containing perlite+ peat+expanded clay (25%+70%+5%) was the best treatment. In this substrate, flower number, flower diameter, shoot diameter, stem neck diameter, flower height and vase life showed significant difference among growing media.
