Deficit irrigation as a limiting factor for growth, affects the plant's yield characteristics. Therefore, The aim of this study was to investigate the effect of cultivation type: monoculture tomato (T), monoculture basil (B) and intercropping (50T:50B), and different moisture levels including four irrigation periods based on soil field capacity (FC): irrigation without water stress in the root zone 0.85‒1FC, and deficit irrigation levels of 0.7‒0.85FC, 0.5‒0.7FC and 0.3‒0.5FC, with a factorial arrangement (with two factors) in a completely randomized design and a total of 12 treatments in three replications. Plant characteristics including greenness index, stomatal conductance, leaf area index, leaf temperature and fresh and dry weights were measured. Based on the results, the highest fresh and dry weights of aerial part of the tomato were obtained in 0.7‒0.85FC treatment with intercropping (349.73 and 69.42 g per plant) and their lowest values were obtained in the irrigation level 0.3‒0.5FC with monoculture (204.66 and 40.42 g per plant). Tomato leaf area index was not significantly decreased up to water stress level of 0.5‒0.7FC. For basil, the highest fresh and dry weights of the plant (91.71 and 16.39 g per plant) and leaf area index (1845.99 cm 2 per plant) were obtained in monoculture, and at non-stress level and 0.7‒0.85FC, respectively. Tomato was dominant in intra-specific competition with basil and significantly influenced basil yield. Finally, according to the results of this study intercropping of basil and tomato and water level up to 50% of field capacity resulted in reduction of water loss and increased fruit yield of two plants by considering consumed water.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129781171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seaweed extract, as a biofertilizer, enhances plant resistance against abiotic stresses via accelerating seed germination, root growth enhancement and uptake of plant nutrients. The present research was carried out to investigate the effects of foliar spraying of Ascophyllum nodosum seaweed extract on physiological and biochemical characteristics of basil ( Ocimum basilicum L.), Shahre-ray local cultivar, under drought-stress conditions, as a factorial experiment, based on completely randomized design with three replications. Experimental factors included drought stress (full irrigation (control), irrigation holding at first stage of flowering, irrigation holding at 50% of flowering) and foliar spraying of different concentrations of seaweed extract (0, 0.5, 1 and 2 g/L). Control plants were sprayed with distilled water. Results indicated that as drought-stress intensity was increased, morphological traits such as number of lateral shoots, fresh and dry weights of plant, number of leaves, leaf area, root dry weight and biochemical parameters such as chlorophyll a , chlorophyll b , total chlorophyll, carotenoid content and relative water content of leaves were reduced, while free proline content of leaves and electrolyte leakage from cell membranes were increased. Foliar spraying of 2 g/L seaweed extract significantly reduced the effects of drought stress on basil plants. In general, the results of this research indicated that exogenous application of seaweed extract enhanced basil plant growth under drought-stress conditions via increasing proline content, osmotic adjustment, inhibition of chlorophyll degradation and decreasing the electrolyte","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121960162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to determine the effect of humic acid on some morphological and physiological characteristics and uptake of elements by strawberry ( Fragaria ananassa Duch. cv. Sabrina) under salinity stress, a greenhouse factorial experiment was conducted with three factors including two treatment methods of humic acid application (spray and drench), three humic acid levels (0, 300 and 600 mg/L) and three salinity levels (0, 20 and 40 mM NaCl) in a completely randomized design with four replications. Results revealed that in the salinity level of 40 mM, the dry weights of shoot and root were reduced by 36.65 and 26.85 percents compared to control. With increasing the salinity level, the Na + concentration increased and the K + , Ca 2+ and Mg 2+ concentrations in leaves and roots decreased. In the presence of 40 mM NaCl in external media, application of 600 mg/L humic acid increased root Ca 2+ concentration by 65 %. However, application of humic acid mitigated the Na + concentration in leaves and roots and improved the Fe 2+ and Zn 2+ concentrations. According to the results of this study, application of humic acid (especially at 600 mg/L) ameliorated the deleterious effects of salt stress in strawberry cv.

Capitata) in floating system. The experiment was conducted as completely randomized design, with 8 treatments and 3 replications, in Research Greenhouse of Shahrekord University. Treatments (different concentrations of Ca and N (mg/L) in the nutrient solution) included T 1 (N60 + Ca80), T 2 (N80 + Ca80), T 3 (N100 + Ca80), T 4 (N120 + Ca80), T 5 (N120 + Ca160), T 6 (N160 + Ca160), T 7 (N200 + Ca160) and T 8 (N240 + Ca160). Results showed that there was no significant difference between treatments for number of leaves; but significant differences were observed in tipburn percent, leaf and root fresh weight, leaf and root dry weight, and stem length and diameter. The highest head weight, length and diameter of stem, and root and leaf dry weight were observed in T 1 (N60 + Ca80), T 2 (N80 + Ca80) and T 3 (N100+ Ca80) treatments. The weight of head in different treatments varied from 218 to 326 g/plant. Increasing the N concentration to more than 100 mg/L decreased the yield. Higher yield was obtained in 80 mg/L Ca concentration as compared to 160 mg/L. The tipburn occurrence of the treatments varied from 10.5 to 42.5 percent. The lowest tipburn occurrence was observed in T2 and T6 (N:Ca=1) treatments; while it was highest in T1 and T5 (N:Ca=0.75) treatments. Leaf analysis showed that significant difference was observed among the treatments with respect to N and Ca content. The T2 treatment (N80 + Ca80) was the best due to its high yield and lower tipburn incidence.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114269732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
