The production of the turnip (Brassica napus L.) in Ecuador, depends largely on the use of agrochemicals, whose indiscriminate use causes negative effects on the environment. Agricultural homeopathy has emerged as an ecological alternative to improve the health status of plants. In order to help improve the sustainable production of vegetables, the effect of two centesimal dynamics (7CH and 31CH) of three homeopathic medicines for human use was evaluated: Silicea terra (SiT), Natrum muriaticum (NaM) and Phosphoricum acidum (PhA ), on the germination, emergence and vegetative development of B. napus plants, applying a completely randomized 2×3+1 block design with three repetitions for the three stages of the crop. The variables evaluated during germination and emergence were: percentage of germination and emergence, length of stem and radicle, fresh weight of the aerial part and radicle, dry weight of the aerial part and radicle. The variables evaluated during vegetative development were: plant height, stem diameter, number of leaves, weight, leaf area and productive yield. Signif icant differences were recorded in all the variables and stages of development studied. The highest germination values corresponded to SiT-7CH and PhA-7CH (100%), surpassing the control group (83.5%). The PhA-7CH and NaM-31CH treatments stimulated stem growth in the germination stage (3.40 cm) and NaM-7CH root growth (4.07 cm) in the emergence stage. During the vegetative development, the plants with the highest production were those treated with NaM-7CH. The highest prof itability of the crop (71.33%), with a benef it / cost ratio of 1.7% was obtained with SiT-7CH. The results obtained suggest that agricultural homeopathy has potential in horticulture, since all treatments favorably influenced the response variables during germination, emergence and vegetative development of (Brassica napus L.).

The application of bioactive substances in a minimum dose is an alternative to reduce the application of harmful agrochemicals in agriculture, particularly vegetables. The objective of this research was to evaluate the effect of four homeopathic medicines during germination, emergence, and vegetative development of cucumber plants (Cucumis sativus L.). The experimental design included two centesimal homeopathic dynamizations (7CH and 13CH) of Silicea terra (SiT), Natrum muriaticum (NaM), Magnesia phosphorica (MaP), and Arsenicum album (ArA) and a control (water) treatment. A completely randomized 2 × 4 + 1 block design was used in three repetitions. The variables evaluated were rate and percentages of germination and emergence, stem and radicle length, and fresh and dry weight of the aerial part and radicle. Additionally, during the vegetative development the diameter of the stem and the number of leaves and flowers were evaluated. With ArA-13CH, significant differences in germination were observed (53.33%) and with NaM-13CH longer stem length (107.07 cm) during vegetative development, compared to the control group (78.63 cm). Radicle length showed significant differences with the application of SiT-7CH (49.59 cm) compared to the control group (28.6 cm). During germination the best result in the radicle fresh and dry weight was recorded when applying ArA-13CH. In emergence, the greatest fresh radicle weight was obtained with MaP-13CH, and the largest stem diameter, number of leaves and number of flowers were obtained with NaM. The results obtained confirmed that the evaluated homeopathic medicines positively affected the initial stage and vegetative development of cucumber (Cucumis sativus L.) under controlled conditions. This research represents an advance in agricultural homeopathy for the sustainable management of vegetable cultivation.

Aims: This study aimed to optimize the levels of gibberellic acid (GA3) and plant spacing on growth and yield of lettuce. Study Design: The experiment was laid out in Randomized Complete Block Design with three replications. Place and Duration of Study: Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka-1207, from November 2013 to January 2014. Methodology: The experiment consisted of two factors. Factor A- two levels of gibberellic acid (GA3,) application, viz. G1= 25 ppm and G2= 50 ppm in relation to a control G0 and factor B- four plant spacing viz. S1=15cm x 15cm, S2=20 cm x 20 cm, S3=25 cm x 25 cm and S4=30 cm x 30 cm. GA3 was applied twice as a foliar application by hand sprayer at 20 and 30 days after sowing. First, second and final harvesting was done at 25, 35 and 45 days after sowing respectively. Results: The growth and yield characters of lettuce showed significant variation for different levels of GA3 and plant spacing. Among GA3 levels, 25 ppm GA3 produced the maximum number of leaves (15.6), leaf area (283.9 cm2), fresh weight (91.6 g plant-1), dry weight (11.8 g plant-1), fresh yield (1794 g plot-1) and gross yield (12 t ha-1) at final harvesting compared to control where GA3 was not used. Under plant spacing, highest plant height (17.5 cm), leaf area (281.1 cm2), fresh weight (99.1 g plant-1) and dry weight (12.1 g plant-1) was revealed from wider spacing 30 cm x 30 cm followed by optimum spacing 25cm x 25cm. Meanwhile, closure spacing 15 cm x 15 cm showed maximum fresh yield (1710 g plant-1) and gross yield (15.5 t ha-1) due to higher plant density at final harvesting. Besides, lower chlorophyll content (0.43%) and the highest number of leaves (16.2) was found from 25 cm x 25 cm at final harvesting. So, optimum spacing 25 cm x 25 cm would be more suitable considering different points of view. Moreover, the treatment combinations 25 ppm GA3 with 25 cm x 25 cm exhibited highest benefit-cost ratio (2.04) than other treatments. Conclusions: It is concluded that the combinations 25 ppm GA3 application with 25cm x 25cm spacing would be optimum for better growth and yield of lettuce

The effect of 15- and 30-cm row spacings and 1.5, 3.0, 6.0 and 12.0 kg ha−1 seeding rates on growth characteristics, as measured by growth analysis, of summer rape (Brassica napus L.) was studied under southern Manitoba growing conditions. Growing degree days (GDD) was used in the growth analysis formulae as a measurement of time. Over all seeding rates, summer rape grown in rows spaced 15 cm apart produced more dry weight (W), a greater leaf area index (LAI) and a greater leaf area duration (LAD) than when grown in rows spaced 30 cm apart. The 15-cm row spacing treatments had a higher crop growth rate (CGR) and a greater net assimilation rate (NAR) than the 30-cm row spacing treatments. Summer rape grown at seeding rates of 6.0 and 12.0 kg ha−1 had a greater W, LAI and LAD during vegetative development than summer rape grown at seeding rates of 1.5 and 3.0 kg ha−1. This was primarily due to increased plant density. After flowering there were no differences for W, LAI and LAD attributable to differences in seeding rates. Summer rape grown at seeding rates of 6.0 and 12.0 kg ha−1 had a lower CGR and NAR during flowering than that grown at 1.5 and 3.0 kg ha−1 seeding rates indicating that plants produced from lower seeding rates were more photosynthetically efficient than plants produced from higher seeding rates.Key words: Brassica napus, growth analysis, row spacing, seeding rates, rape (summer)

Agrochemical use in horticultural cultivations generates negative effects, thus the need for searching to decrease or eliminate its use by means of other less toxic techniques. Agricultural homeopathy represents an alternative for ecological agriculture, impacting positively in cultivation development. The effect of four homeopathic medicines for human use were assessed in two centesimal dynamizations (7CH and 13CH) [(Silicea Terra (SiT), Natrum muriaticum (NaM), Zincum phosphoricum (ZiP) and Phosphoricum acidum (PhA)], and a control treatment (distilled water) on tomato plant germination, emergence, and initial development. The treatments were established under a randomized complete block design with three repiclates. Germination and emergence rate and percentage and morphometric variables (plant height, radicle length, dry and wet weight) were assessed, including the variables in stem diameter and wet and dry leaf weight, number of branches, leaves, and buds in the vegetative development stage. Signif icant differences were observed in all the morphometric variables assessed in function of the different development stages, homeopathic medicines, and their different dynamizations. During germination, greater growth in stem length was observed with ZiP-7CH (5.5 ± 0.98 cm) compared to the control group (4.3 ± 1.10 cm). During the emergence stage, the treatments SiT-7CH (6.6 ± 1.11 cm) and ZiP-7CH (5.9 ± 1.41 cm) increased stem length signif icantly whereas with PhA-7CH, the best effects were obtained in the variables assessed during the vegetative development stage, LT (94 ± 8.31 cm), leaf number (No hojas) (131 ± 27.71), fresh stem biomass (BFT) (17.20 ± 2.45 g), wet leaf biomass (BFH) (30 ± 7.72 g), dry leaf biomass (BSH) (2 ± 0.61 g), fresh root biomass (BFR) (10 ± 6.26 g), dry root biomass (BSR) (1 ± 0.43 g), and number of flower buds (No H) (6 ± 7.10). The homeopathic medicines applied impacted positively during the initial and vegetative development stages of tomato under controlled conditions. This research study represents and advance in the sustainable management of tomato cultivation.
