<p><span>A field experiment was conducted to evaluate yield and some qualitative characteristics of four cultivars of sweet basil treated with different levels of nitrogen fertilizer. The experiments were located on the Agricultural Research Station of Khorramabad, Iran, during the 2016-2017 growing season. Treatments were arranged in factorial split-plot-in time in randomized complete block design with three replications. Experimental treatments were four cultivars of sweet basil (<em>Ocimum basilicum</em> ‘Italian Large Leaf’, <em>O. basilicum</em> ‘Mobarakeh’, <em>O. basilicum</em> ‘Cinnamon’ and <em>O. basilicum </em>‘Thai’), three levels of nitrogen fertilizer (0, 100 and 200 kg ha<sup>-1</sup> urea) and three harvests. The highest total dry mass (3482.4 kg ha<sup>-1</sup>) was related to ‘Italian Large Leaf’ with the application of 200 kg ha<sup>-1</sup> urea at the second harvest. The maximum (26.79 kg ha<sup>-1</sup>) essential oil yield belonged to 100 kg ha<sup>-1 </sup>urea. The highest concentrations of main constituents of essential oil, except methyl chavicol, 1,8-cineole and methyl cinnamate were obtained by control (without nitrogen fertilizer). Italian Large Leaf cultivar and application of 100 kg ha<sup>-1</sup> urea are recommended to access an acceptable agricultural yield and essential oil yield in sweet basil under the environmental condition similar to Khorramabad</span></p>

Trees sampled from a loblolly pine mid-rotation fertilization trial were used in this study. The study was laid out in a randomized complete block design with four levels of nitrogen fertilizer as treatments: control (000N), 112 (112N), 224 (224N), and 336 (336N) kg/ha of nitrogen, with each treatment replicated in 4 blocks. Two trees were destructively sampled from each plot giving a total of 32 trees. Bolts 0.6 m in length were collected from each tree (3 bolts per tree); with the midpoint of each bolt at heights of 2.4, 7.3 and 12.2 m from the base of the tree (each bolt represented the midpoint of standard 4.9 m saw logs). Static bending samples with dimensions 25 by 25 by 406 mm (radial, tangential and longitudinal dimensions respectively) were cut from the bolts that included the 25 mm of wood produced immediately following fertilization. Data on modulus of elasticity (MOE, stiffness) and modulus of rupture (MOR, strength) were collected from clear static bending samples. Based on the analysis of variance, no significant treatment effect was observed on MOE and MOR. However, MOE and MOR decreased in wood produced immediately after fertilization for trees which received the highest level of fertilization (336N). A decreasing trend in MOE and MOR with height was also present.

An experiment was conducted during 2015-2016 as a split factorial in a randomized complete block design (RCBD) with three replications. Experimental factors were nitrogen fertilizer at four levels 0, 50, 100 and 150 kg/ha as the main factor and two types of green manure. Alfalfa (Medicago sativa) and secale (Secale montanum) in two states (use and non-use) were considered as sub-factors. Medicago sativa and Secale montanum were cultivated as green manure in September 2015 and returned into the soil by ploughing at the fall of 2015. Thereafter, Mentha piperita was planted and the crop was taken care of in order to collect the samples. The highest increase of peppermint essential oil percentage and essential oil yield in different treatments resulted from the application of 150 kg/ha of pure nitrogen with 0.35% and 45.60 kg/ha, as well as the use of M. sativa with 0.43% and 55.80 kg/ha, the use of S. montanum with 0.44% and 49.50 kg/ha, respectively. The highest essential oil percentage and essential oil yield were recorded under the influence of the double interaction use of 150 kg/ha of pure nitrogen and use of green manure of M. sativa with average 0.62% and 80.30 kg/ha, respectively. The triple interaction of experimental factors on traits tested showed that nitrogen treatment of 150 kg/ha with M. sativa and S. montanum produced the highest percentage of essential oil and essential oil yield of average 0.73% and 91.65 kg/ha, respectively.

Abstract Intercropping is an important and sustainable cropping practice in agroecosystems. Intercropping is a planting technique that farmers and gardeners can use to promote beneficial plant interactions and increases in biodiversity, enhanced production and lower economic risk. In the search for sustainable agricultural methods for medicinal plants, fenugreek and dill plants were intercropped at different additive (1:20, 1:40 and 1:60) and replacement (1:1, 1:2 and 1:3) series, at the Research Farm of the Faculty of Agriculture, University of Tabriz, Iran. Field experiment was arranged as split plot based on randomized complete block design in three replicates. Dill umbels were harvested at flowering, pasty and complete ripening stages. Results showed that among harvesting times, pasty stage had maximum essential oil percentage, essential oil yield and harvest index of essential oil, whereas among intercropping patterns, 1:1 and 1:20 treatments had the maximum values. Fenugreek as a medicinal, forage and legume crop promote dill essential oil yield and harvest index and could be an effective plant in intercropping systems.

ABSTRACT: The objective was to estimate the wood yield and essential oil content in three clones of eucalyptus that were planted in four contrasting arrangements and intercropped with sorghum. Eucalyptus clones MA2001 (Eucalyptus camaldulensis x E. tereticornis), A144 (Eucalyptus urophylla x E. grandis), and GG100 (Eucalyptus urophylla x E. grandis), were planted in single rows (10x2m), double rows (2x3+15m and 2x3+20m); and, triple rows (2x3x2+10m) in a randomized, complete block design experiment with four replicates. Our results demonstrated that planting spacing did not influence the essential oil yield or diameter at breast height in the clones. However, higher density plantings were shown to result in higher fresh weight of branches and leaves per plant. MA2001 grew taller, produced higher quantity of fresh biomass of branches and leaves per plant and volume of wood per hectare, and yielded more essential oil yield than the other clones. We concluded that MA2001 is the most suitable of the clones tested here for cultivation in water deficit conditions.

Abstract In order to evaluate flower yield and essential oil content of Rosa damascena, 49 landraces were studied in a randomized complete block design with three replications in Sanandaj (Iran) during 2004-8. An analysis of variance revealed significant differences (p ≤ 0.01) for the number of flowers per plant, flower and petal weight, flower and petal yield per plant, essential oil ratio and essential oil yield per plant among landraces (G), years (Y) and for landrace × year (GY). The landraces of FA1, KR2, KR3, FA2, AR1 and YZ2 with 3291.9, 2526.4, 2298.7, 2239.8, 2077.6 and 1978.7 kg ha−1, respectively, produced the highest flower yield and the landraces of IS3, IS2, KR2, IS4 and FA2 with 413.25, 378.11, 364.31, 315.30 and 296.10 g ha−1, respectively, produced the highest essential oil among all of the landraces. In accordance to this, cluster analysis also classified high flower and essential oil yield landraces in distinct groups at an 87% similarity. According to the results, most landraces that originated from temperate, warm temperates and arid regions such as the FA2, YZ2 and Isfahan group of landraces produced higher flower yield and essential oil than those from cool, cool temperate, semi-arid and humid regions. Taking into consideration flower yield and essential oil, the landraces of KR2, YZ2, IS3, IS2 and FA2 with 2526.4, 1978.7, 1659.8, 1663.2 and 2239.8 kg ha−1 flower yield, respectively, and 364.31, 265.31, 413.25, 378.11 and 296.10 g ha−1 essential oil, respectively, produced the highest flower yield and essential oil content among the landraces and are recommended for semi-temperate and cool areas.

The quantitative yield and essential oil percentage and composition of two important savory species in response to various fertilizers were explored in a field experiment as a factorial study based on a randomized complete block design with three replications in north Lorestan, Iran, in 2017–2019. The first factor was assigned to three mycorrhizal fungi (Funneliformis mosseae, Rhizophagus irregularis, and Glomus fasciculatum), phosphate biofertilizer (Baravar-2), fish manure (800 kg/ha), cattle manure (20 t/ha), vermicompost (5 t/ha), and a control (no fertilization); the second factor was assigned to two savory species, including Satureja khuzestanica and S. rechingeri. The results of the combined analysis of variance for the second and third years showed that the simple effects of fertilizers and species were significant on all recorded traits, except for some constituents of the essential oil. Among the mycorrhizal fungi, R. irregularis and S. khuzestanica outperformed S. rechingeri in all traits, except for essential oil content and yield. The interaction between year and species was significant for all traits. The essential oil content of S. rechingeri in the third year (5.1%) was 18% higher than that of S. rechingeri in the second year (4.3%) and 41% higher than that of S. khuzestanica in the third year (3.6%). According to the results, the foliar application of vermin compost at a rate of 5 t/ha can contribute to the sustainable production of both savory species, improving their growth and essential oil yield.

To evaluate the effect of head pruning and different nutritional systems (chemical, biological and integrated) on yield and seed oil content in medicinal pumpkin (Cucurbita pepo L.), an experiment was conducted in Kermanshah/Iran during the 2013 growing season. The experimental treatments consisted of two levels - no head pruning, control (Co) and head pruning (C1) allocated to the main plots. Four levels of different fertilizing systems - control (without fertilizer) (T0), chemical (T1), biological (a combination of nitrogen fixing bacteria, Azospirillum brasilense and Glomus mosseae) (T2), and integrated fertilizing system (biological fertilizer + 50% chemical fertilizer) (T3) were assigned to the sub-plots. The experimental treatments were arranged as a split plot based on a randomized complete block design with three replications. The results showed that the highest percentage of seed oil was obtained (37%) in the integrated nutritional system along with the head pruning treatment. The highest grain yields of 53 and 50 g per square meter were obtained in integrated and chemical fertilizing systems, respectively while no pruning was applied. The highest fruit yields of 3,710 and 3,668 kg per hectare were produced by chemical and integrated fertilizing systems, respectively. The biological nutrition system required more time to demonstrate its positive effect on the growth and yield of medicinal pumpkin.

Taro (Colocasia esculenta L. Schott) is a plant that has an excellent economic and healthy value, as well as a great potential development of Bengkulu coastal area. That is because taro has wide adaptability, and can be consumed both as a staple food and healthy food alternative. This research was conducted to study the vegetative growth of two cultivars of taro given four different doses of nitrogen. This study applied a Randomized Complete Block Design (RCBD) with two factors. The first factor was the cultivar of taro consisted of two levels, namely Taro Satoimo (T1) and the Taro Local (T2). The second factor was the doses of nitrogen fertilizer which consisted of four levels namely: N0 = 0 kg / ha (control), N1 = 50 kg / ha (2.6 g, N2 = 100 kg / ha, and N3 = 150 kg / ha. Thus, obtained eight treatment combinations. Each treatment was repeated three times to get 24 plots. The results showed that based on increased vegetative growth, the cultivar Satoimo has a faster response than local cultivar. Satoimo has demonstrated another advantage because it produced some leaves and number new shoot. The best dose of nitrogen fertilizer on the vegetative growth of taro in the coastal area of Bengkulu is 150 kg/ha.
