Water spinach (Ipomoea reptans Poir) had been identified as a nutritious vegetable with high demand in Indonesia. Besides, this plant also has been evidenced to play an important role in environmental cleaning as phytoremediator. The study about the effect of organic fertilizers on the growth and yield of water spinach (Ipomoea reptans Poir) has been conducted in the Green House of Biology Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. The study aims to investigate the most effective type of fertilizers and the dose for water spinach’s (Ipomoea reptans Poir) growth and yield. A Completely Randomized Factorial Design was designed for the experiment with two factors and three repetitions. The first factor is the type of fertilizer (chicken manure, cow manure, and compost), and the second factor is the dose of the fertilizer (1:1, 2:1, and 3:1). The parameters such as plant height, number of shoots, number of leaves, fresh weight, dry weight, leaf’s total chlorophyll content, and water content were measured to evaluate plant growth and yield. The General Linear Model used SPSS 21 programs was applied to analyze the collected data. Study results revealed that cow manure increased plant growth and yield significantly with dose 2:1 as the finest treatment, followed by dose 3:1. Cow manure also increased total chlorophyll content (8.0574c mg. L-1), with the most suitable dose was 2:1 (8.2807 mg. L-1). The plant’s water content tended to be high in chicken manure (93%), and the lower water content was in cow manure with dose 3:1 (87.5%).

Field experiment on production systems of `Selva' day-neutral and `Totem' June-bearing strawberry was established in 1995 on the spring-killed cover crop mulched plots using randomized complete-block design. Seven soil cover treatments consisted of `Wheeler' rye (Secale cereale) and `Micah' and `Steptoe' barley (Hordium vulgare), `Micah' residue applied on soil surface, a wedge of perlite (artificial medium) placed next to strawberry row, perlite with `Wheeler' rye, and no treatment were used. During the early summer, cover crops were replanted between strawberry rows and mowed down after 6 weeks. In both cultivars, plant growth doubled during mid-summer, and `Micah'on surface produced better growth than the growth in other treatments. No significant difference was found on CO2 assimilation rate (mmol·m–2·s–1), leaflet length, and number of leaves and runners among treatments (P ≥ 0.1). Yield of `Totem' was ignored during the establishment year. In `Selva', `Micah' residue on surface produced 36% more crowns per plant and the greatest total yield than that of any other treatment. `Micah' on surface produced 50% more shoot biomass and 45% greater yield compared to `Micah' barley planted in the plot. Total `Selva' yield was 61% greater in perlite treatment than the yield in perlite with `Wheeler' rye and 31% greater than the control treatment. Comparison of `Selva' strawberry total yield and average fruit production between cover crops vs. control treatment using non-orthogonal contrast indicated no significant difference might suggests no detrimental interaction between cover crops and strawberry.

Growth and yield responses of pepper (Capsicum annuum L.) hybrid Nathalie to a bovine vermicompost leachate Resumen El pimiento (Capsicum annuum L.) es una hortaliza muy apreciada en el mundo por sus propiedades nutritivas, sus aplicaciones médicas y como condimento a los alimentos. En Ecuador se cultiva en varias provincias, y en todos los casos se utilizan altas cantidades de fertilizantes químicos sintéticos. Una opción es el empleo de bioestimulantes orgánicos que permiten producciones limpias. Este trabajo tuvo como objetivo investigar las respuestas del crecimiento y el rendimiento del pimiento híbrido Nathalie a la aplicación de un lixiviado de vermicompost bovino (LVCB). Se ensayaron seis tratamientos experimentales: suelo sin fertilizar, fertilizante químico YaraMilaTM ComplexTM, y tres diluciones de LVCB (1:10, 1:20 y 1:30 v/v). Las variables del crecimiento evaluadas fueron la altura de las plantas, el diámetro del tallo, la cantidad de hojas y el contenido de clorofilas totales a los 15, 30 y 45 días después del trasplante. Las variables del rendimiento (longitud, circunferencia y peso de los frutos) se midieron en cuatro cosechas. Se calculó el rendimiento estimado por hectárea a partir del peso total de los frutos de las cuatro cosechas y el área ocupada por las plantas muestreadas. No se observaron diferencias significativas en las variables del crecimiento y el contenido total de clorofilas entre los tratamientos experimentales. Los rendimientos estimados de todas las diluciones de LVCB fueron similares a los obtenidos con fertilizante químico y superaron al suelo sin fertilizar. Los resultados obtenidos sugieren que el uso de LVCB puede convertirse en una alternativa sostenible para la producción de pimiento sin contaminar el medio ambiente. Palabras clave: pimiento; Capsicum annuum L.; bioestimulantes. Abstract The pepper (Capsicum annuum L.) is a vegetable highly prized in the world for its nutritional properties, medical applications and as a condiment to food. In Ecuador it is grown in several provinces, and in all cases high amounts of synthetic chemical fertilizers are used. One option is the use of organic biostimulants that allow clean productions. This work aimed to investigate the growth and yield responses of the Nathalie hybrid pepper to the application of a leachate of bovine vermicompost (LVCB). Six experimental treatments were tested: unfertilized soil, YaraMilaTM ComplexTM chemical fertilizer, and three dilutions of LVCB (1:10, 1:20 and 1:30 v/v). The growth variables evaluated were the height of the plants, the diameter of the stem, the amount of leaves and the total chlorophyll content at 15, 30 and 45 days after transplantation. The yield variables (length, circumference and weight of the fruits) were measured in four crops. The estimated yield per hectare was calculated from the total weight of the fruits of the four crops and the area occupied by the sampled plants. No significant differences were observed in the growth variables and the total chlorophyll content between the experimental treatments. The estimated yields of all dilutions of LVCB were similar to those obtained with chemical fertilizer and exceeded the soil without fertilizing. The results obtained suggest that the use of LVCB can become a sustainable alternative for pepper production without polluting the environment. Keywords: pepper; Capsicum annuum L.; bioestimulants.

Knowledge of the minimum rate of glyphosate required to eradicate sugarcane ratoons can reduce the amount of herbicide used. To confirm this hypothesis, this study aimed to investigate the tolerance of different sugarcane cultivars to chemical eradication, at different glyphosate rates. The experiment was conducted in a randomized block design in a split-plot scheme, with four replications. The sugarcane cultivars (IACSP94-2094, IACSP94-2101, IACSP93-3046, IACSP94‑4004, IAC86-2480, and RB72454) were allocated in plots and the glyphosate rates (0, 1,440, 2,160, 2,880, 3,600, and 4,320 g ha-1), in the sub plots. The traits evaluated were signs of poisoning symptoms; total chlorophyll content, plant height, percentage of dead tillers, and dry weight of the plants. At 45 days after application (DAA), the glyphosate rate of 1,440 g a.e. ha-1 eradicated the cultivars IACSP94-2094 and IACSP94-2101, as well as RB72454 with application of 2,160 g a.e. ha‑1. Application of glyphosate 2,880 g a.e. ha-1 eradicated both IACSP93-3046 and IAC86-2480 and glyphosate 3,600 g a.e. ha-1 eradicated IACSP94-4004. The most tolerant cultivar was IACSP94‑4004, eradicated at the rate of 3,600 g. a.e. ha-1. This confirms the hypothesis that knowing the cultivar's tolerance leads, in practice, to a smaller amount of herbicide applied to the environment, which also reduces production costs.

Abstract Many of the world’s findings indicate the positive effect of earthworms on soil parameters, and consequently, on the formation of phytomass of cultivated plants. In our experiment we studied: A) the influence of soil itself, soil mixed with vermicompost in a ratio of 9:1; B) the influence of earthworms number (genus Eisenia foetida, 10 and 20 individuals per pot) supplied to soil mixed with vermicompost in the ratio of 9:1 on the dynamics of changes in the weight of radish roots, the total chlorophyll content in leaves and the selected qualitative parameters of the roots. The results obtained showed that one tenth proportion of vermicompost from the total weight of soil substrate caused the statistically significant increase in the total chlorophyll content in leaves, the increase in yield of radish roots, the reduction of the vitamin C content and the increase of nitrate content in the roots. The impact of earthworms on the chlorophyll content in leaves and on the root weight was negative. The addition of 10 individuals of earthworms into 20 kg of substrate (soil + vermicompost) resulted in the increased content of vitamin C and the decreased content of nitrates in the radish roots. Twenty earthworms added to vermicompost, compared to vermicompost alone, did not affect the vitamin C content and reduced the nitrate content.
