Litsea Cubeba

Mountain pepper (Litsea cubeba (Lour.) Persoon) is an important oil plant used as an ingredient in edible oil, cooking condiments, cosmetics, pesticides, and potential biofuels. Zinc and boron are essential micronutrients for plant growth. However, the effects of zinc and boron on the yield, yield component, oil content, and citral content in L. cubeba have not been determined. This study was conducted to evaluate the efficacy of the foliar application of zinc, boron, and multiple micronutrients (zinc + boron) on the yield, yield component, oil content, and citral content of three varieties (Fuyang 1 (FY1), Jianou 2 (JO2), and Jianou 3 (JO3)) of L. cubeba. Zinc sulfate (0.25%), boric acid (0.25%), and zinc sulfate (0.25%) + boric acid (0.25%) were sprayed on selected trees at five different times at full bloom and 28 days before harvest, once every seven days. The results indicated that Zn had a negative effect on the yield, yield component, oil content, and citral content of the FY1, JO2, and JO3 varieties compared to the untreated trees. B had positive effects on the yield, yield component, oil content, and citral content of the JO2 and JO3 varieties but not on those of the FY1 variety when compared to the untreated trees. The highest levels of yield, yield component, oil content, and citral content for all three varieties were obtained with the combined application of zinc sulfate + boric acid. Hence, the foliar application of multiple micronutrients (zinc + boron) is an effective method to improve the yield, oil content, and citral content in L. cubeba. In addition, the 100-fruit weight (HFW) was positively correlated with the yield, oil content, and citral content and could be used as a tool to select new cultivars with high yield, high oil content, and high citral content under zinc sulfate, boric acid, and zinc sulfate + boric acid applications in L. cubeba.

This study was carried out during 2017 and 2018 seasons, in order to investigate the effect of single and combined application of potassium sulphate (K2SO4), ferrous sulphate (FeSO4) and boric acid (H3BO3) on fruit physical, chemical properties and maturation of Wonderful pomegranate trees grown in sandy soil under Minia Governorate conditions. Results showed that increasing the concentration of K2SO4 from 0.5 to 1.5%, FeSO4 from 100 to 200 ppm or/and H3BO3 was very effective in fruit weight (g). While, the three examined compounds significantly decreased fruit cracked (%) and fruit sunburned (%) during the two experimental season. Application of the three examined compounds together significantly surpassed than untreated control or each compound alone terms of improved fruit physical and chemical properties, while, juice total acidity was significantly decreased. For producing favorable fruit physical properties of Wonderful pomegranate grown under sandy soil, it is necessary to spray the trees with mixture of potassium sulphate at 1.5%, ferrous sulphate at 200 ppm and boric acid at 100 ppm three times yearly during the fruit growth cycle.

The effect of zinc sulfate and zinc chelate on the leaf mineral content, yield and fruit weight of the peach variety Andross was investigated in a Greek orchard. Foliar application of a 25% zinc sulfate solution on 25 February and 2% zinc chelate solution on 20 May increased the zinc content of leaves and no toxicity was observed. In contrast, foliar application of 6% zinc sulfate and soil application of zinc sulfate at a rate of 200 g/tree on 25 February did not affect the zinc content of leaves. However, zinc sulfate applied to the soil at a rate of 200 g/tree significantly increased fruit yield. Statistically, the mean fruit weight and the susceptibility of fruit to Monilinia laxa did not differ between treatments. However, postharvest fruit susceptibility to M. laxa increased when fruit were dipped in a zinc chelate solution.

Water is essential for crops and plays a vital role in olive (Olea europaea) growth. Three irrigation treatments, rain-fed (CK), flood irrigation (FI), and drip irrigation (DI), were applied from late November to late May in a 2-year study (Nov. 2015 to Oct. 2017) on two olive cultivars, Coratina and Koroneiki. Shoot growth, flower and fruit characteristics, and olive and oil yields were measured. Compared with CK, FI had significantly higher values of vegetative growth, olive and oil yields, moisture content, and oil content. Although the fruit weight, pulp rate, and oil content with DI were the lowest, our results support that DI had the greatest positive effects on olive vegetative growth, flowers, fruit set, and olive and oil yields. It is suggested that DI in winter and spring is the best irrigation strategy for olive productivity in southwest China.

Various growth regulators have been used to improve the quality of different fruit crops. Foliar spray of macro and micronutrients play an important role in vegetative growth, yield and fruit quality. In the present study, the influence of foliar application of growth regulators and nutrients on fruit splitting and fruit quality was evaluated. For that purpose, Naphthaleneacetic acid (NAA), Potassium nitrate (KNO3) and Boric acid (H3BO3) at the rate of 40 ppm, 1% and 0.3% were used respectively. Spray of chemicals were applied in 2nd and 8th week from full bloom to yield in pomegranate cultivar ‘Golden pearl’. The experiment was designed under Randomized Complete Block Design (RCBD) comprised with seven treatments and replicated thrice. Fruit splitting was reduced (48.68%) significantly with application of KNO3 + Boric acid, while maximum fruit size (60.26 cm2), fruit weight (84gm), fruit grain weight (136.38gm), total soluble solid (TSS) 12.52% and yield (21.9kg/plant) were observed in KNO3 + Boric acid. Moreover, peel weight was increased in control (60.66 gm) and minimum was observed in 48.62 gm in KNO3 + Boric acid. Finally, it is concluded KNO3 %+ Boric acid reveled best results against fruit splitting % and other fruit quality parameters. These findings show that application of KNO3+ Boric acid significantly influences fruit quality of pomegranate when fruit are in the beginning stages of growth and development.

This investigation was conducted during the 1991, 1992, and 1993 seasons to study the effect of different concentrations and number of sprays urea and/or boric acid on yield and berries quality of Red Roomy grapevines. Two, three, four, or five sprays for both urea at 0.5% 1%, or 1.5% and /or boric acid at 0.1%, 0.2%, or 0.3% in addition to the control treatment were applied. Combined sprays of urea and boric acid was preferable in increasing the number of clusters, yield per vine, berry set parentage, fertility coefficient. weight, length and shoulder of cluster, weight and dimensions of berry, total soluble solids, total sugars, and total anthocyanins in grapes and in reducing the percentages of cracked and shot berries and the total acidity compared with the single application of both. Spraying urea at 1.0% in combined with boric acid at 0.2% four times (i.e., at growth start, first bloom, immediately after berry set, and at 30 days later) is recommended for achieving high yield and fairly good berries quality in `Red Roomy' grape vines.

Experiments were conducted for two consecutive years during 2017-19 to study the effect of organic manures, PGPR and micronutrients on yield and quality of ajwain seed. Farm yard manure (FYM) and vermicompost (VC) were used as organic sources at 50% and 75% recommended dose of nitrogen (RDN) as basal dose. PGPRs namely Azospirillum lipoferum, Bacillus megaterium and Frateuria aurantia were used for seed priming. Micronutrients namely ZnSO4 and Fe2SO4 were applied thrice as foliar application @ 0.5% first before flowering, second at 50% flowering and third during grain formation. The results revealed that highest number of umbels plant-1, umbellets umbel-1, number of fruits umbellet-1, seed yield plant-1, seed yield hectare-1, straw yield, biological yield, test weight of seeds and essential oil yield were recorded with the application of 50% RDN through VC, which was on par with 50% RDN through FYM, seed priming with Azospirillum and foliar application of zinc with respect to their individual effect. Maximum essential oil content, fixed oil content and thymol content were also observed in case of application of 50% RDN through VC, seed priming with Azospirillum and foliar application of zinc individually. Highest Benefit Cost Ratio (BCR) of 3.33 was recorded with combined application of 50% of RDN through FYM along with seed priming with Azospirillum and foliar spray of Zn at 0.5%. The integrated use of organic manures, PGPRs and micronutrients could also exert significant influence on yield and quality of Ajwain. It was observed that highest seed yield, yield attributing characters and essential oil yield  and quality parameters were recorded with combined application of 50% of RDN through vermicompost along with seed priming with Azospirillum and foliar application of zinc which was statistically on par with application of 50% of RDN through FYM  along with seed priming with Azospirillum and foliar application of zinc.
