Lettuce (Lactuca sativa L.) is one of the vegetables that are commonly cultivated by using hydroponic systems. Some hydroponic systems require high current expenses in particular for the electricity in order to circulate nutrient solution e.g. in the water culture system – deep flow technique (DFT) -. Electricity costs can be reduced by changing from continuous nutrient flow to intermittent nutrient flow. The aim of this research was to investigate the effect of interval nutrient flow on growth and yield of lettuce. The experiment was conducted in Cirebon from February to April 2018. The experiment was arranged by using randomized complete block design with four treatments: (i) continuous nutrient flow (control), intermittent nutrient flow (nutrient flow during (ii) 15 minutes, (iii) 30 minutes, and (iv) 45 minutes). For each intermittent treatment, the nutrient flow was interrupted for 60 minutes. Each treatment was repeated four times. The result showed nutrient flow interval affected to plant height, shoot diameter, and leaf area at 35 days after planting (DAP). Meanwhile, leaves number, root volume, and fresh weight of harvested crops were not significantly different in all nutrient interval treatments. The highest plant height and shoot diameter were detected in the treatment (ii) nutrient flow during 15 minutes and interruption for 60 minutes, the results were not significantly different to the control – continuous flow treatment. It can be concluded the interval nutrient flow can be used as an alternative of the continuous flow of nutrient solution in hydroponically DFT.

Dois experimentos foram conduzidos concomitantemente em blocos casualizados com cinco repetições. Três cultivares de alface (‘Gloriosa’, ‘Robusta’ e ‘Tainá’) foram cultivadas no mesmo canal hidropônico, sob as seguintes interações: dois sistemas hidropônicos (NFT – técnica do fluxo laminar de nutrientes e DFT – técnica do fluxo profundo, ambos em tubos de PVC) e dois níveis de condutividade elétrica da água – CEa (0,3 e 5,3 dS m–1), no Experimento I; no Experimento II, os mesmos dois níveis de CEa e três intervalos de recirculações das soluções nutritivas (0,25; 2 e 4 h), apenas no sistema DFT. No Experimento I, em geral, os sistemas hidropônicos não promoveram mudanças significativas nas variáveis de crescimento e produção das alfaces. Para o Experimento II, foi viável adotar intervalos de recirculações das soluções de até 2 h (cultivar ‘Robusta’) e 4 h (cultivares ‘Gloriosa’ e ‘Tainá’) no sistema DFT em tubos. De modo geral, apesar das reduções no crescimento e produção da alface utilizando-se água salobra (CEa 5,3 dS m–1), não houve depreciação da qualidade visual do produto para comercialização.   Palavras-chave: Lactuca sativa L., cultivo sem solo, oxigênio dissolvido, salinidade, temperatura da solução nutritiva.     FREITAS, F.

LETTUCE CULTIVATION UNDER DIFFERENT RECIRCULATION INTERVALS OF THE NUTRIENT SOLUTION IN HYDROPONIC SYSTEMS USING BRACKISH WATER     2 ABSTRACT   This study aimed to evaluate the growth and production of lettuce using brackish water under different recirculation intervals of the nutrient solution in hydroponic systems. Two experiments were conducted concomitantly, in a randomized block design with five replicates. Three lettuce cultivars (Gloriosa, Robusta and Tainá) were grown in the same hydroponic channel, under the following interactions: between two hydroponic systems (NFT – Nutrient Film Technique and DFT – Deep Flow Technique, both in PVC tubes) and two levels of electrical conductivity of water – ECw (0.3 and 5.3 dS m–1), in Experiment I; in Experiment II, between the same two levels of ECw (0.3 and 5.3 dS m–1) and three recirculation intervals of the nutrient solution (0.25, 2 and 4 h), only in the DFT system. In Experiment I, in general, hydroponic systems caused no significant changes in the growth and production variables of lettuce. For Experiment II, it was viable to adopt recirculation intervals of the nutrient solution of up to 2 h (cultivar Robusta) and 4 h (cultivars Gloriosa and Tainá) in the DFT system in tubes. Generally, despite the reductions in growth and production of lettuce using brackish water (ECw 5.3 dS m–1), but without deleterious effects on the visual quality of the product for commercialization.   Keywords: Lactuca sativa L., soilless cultivation, dissolved oxygen, salinity, nutrient solution temperature.

In the savanna soil of Nigeria, micronutrient deficiency was not noticed in the past but with the intensification of agriculture over the years, crop exploitation of soil available nutrients, crop removal and adverse cultural practices of farmers have led to the incidence of micronutrient deficiency with negative effect on growth, yield and quality of crops. To enhance micronutrient availability, use and use efficiency to crops, a field experiment was set up on sorghum at Samaru in the Northern Guinea Savanna of Nigeria with foliar Algifol (Alg) nutrients solution and NPK. The objectives of the studies were: To test the effectiveness of the nutrient solution and NPK on growth and yield of sorghum in the Nigeria savanna and to determine optimum rates of application of the nutrient solution on sorghum under a tropical condition. The treatments were four levels each for the nutrient solution, NPK and a combination of both as ½Alg, 1Alg, 1½Alg and 2Alg at the rate of [5:10:15:20ml) of the concentrated solution to 10 litres of water per hectare and 64:32:30 kgha-1 N, P2O5 and K2O being therecommendation for sorghum in the Northern Guinea Savanna. Data were collected on plant height, plant girth, panicle yield, grain yield and stover. The treatments were laid in a Randomized Complete Block Design (RCBD) with three replications. The results showed that plant height and girth were highly significant (P < 0.01) at 9 weeks after planting (WAP) and as well as stover. Head and grain yield were positively and highly significantly correlated (r = 0.69** and 0.62**) with dry matter yield (DMY) indicating a positive relationship amongst the plant parameters in response to treatments. Co-application of the nutrient solution with NPK had greater nutritional efficiency on sorghum in the savanna than their sole application since the nutrient solution is deficient in major plant nutrients.Keywords: Nutrient solution, northern guinea, complementary application and tropical environment.

A pots experiment was conducted at the Department of Biology/College of Education for Girls/University of Anbar during Autumn season of 2018-2019 to study the effect of the salinity irrigation water and spray by humic acid in some of morphological, physiological, growth and yield traits of wheat cv. IPa. The experiment was randomized complete block design (RCBD) with three replications. The first factor was assigned for irrigation by saline water at four level (S0, S1, S2 and S3), while the second factor was the foliar spraying of humic acid in three level (0.0, 1.0 and 1.5 g l-1). The results showed that there was significant reduction in plant height, vegetative dry weight, biological yield and chlorophyll leaves content when the plants were irrigated by saline water approached to 41.09 cm, 0.747 g, 0.849 g plant-1 and 38.67 SPAD, respectively at salinity level of 8.3 ds m-1 compared with the plants which irrigated by fresh water. The total carbohydrates were significantly decreased at the treatment of 8.3 ds m-1 reached 18.71 mg g-1. Spray levels humic acid achieved a significant increase in plant height, dry weight of the vegetative part, biological yield and chlorophyll leaves content sprayed at 1.0 and 1.5 g l-1 compared to no sprayed. Nitrogen concentration was significantly increased, while both phosphorus and potassium were decreased in the vegetative parts of wheat as the salinity of irrigation water increased. However, the increase of humic acid levels led to significant increasing in nitrogen, phosphorus and potassium concentration.

AbstractThis study aimed at determining shoot and root characteristics of cassava as affected by root yield and the influence of soil moisture on vegetative growth and yield. Thirty cassava genotypes were evaluated for morphological and physiological characterization in three locations in Nigeria: Ibadan, Mokwa and Zaria. Randomized complete block design was used with four replicates. Studies on the pasting properties of the genotypes were also carried out. Data were collected on plant height, stem girth, stay-green ability, garri and fresh root weight. Genotypes differed significantly (P < 0.05) across and within locations for shoot and root characteristics. Across locations, genotype 011663 had the highest plant height (132.4 cm); 30572 had the largest stem girth (8.6 cm); and 010040 was the best stay-green (2.2). Genotype 011086 had the highest number of roots per plot (95.7), 950289 had the highest fresh root yield (24.3 t/ha), and 990554 had the highest percentage of dry matter (35.2). Trends in root yields across locations were Ibadan (28.9 t/ha), Mokwa (20.3 t/ha), and Zaria (8 t/ha). Five genotypes IITA-TMS-IBA950289, 010034, 990554, 011807, and 980581 had negligible interactions with the environment and so have broad adaptation and are considered stable; and two clones 011807 and 950166 were found to be the best for pasting properties. Breeding strategies that consider root size, total root number, harvest index, dry matter, with applications for household foods and industrial uses, will be an effective and efficient way to select genotypes for high yield.
