African Leafy Vegetables

African leafy vegetables (ALVs) are nutrient dense and can contribute to crop and dietary diversity, especially in water-stressed environments. However, research on their productivity under limited water availability remains scant. The objective of the study was to evaluate growth, physiology and yield responses of three ALVs (Vigna unguiculata, Corchorus. Olitorius and Amaranthus cruentus) and a reference vegetable (Beta vulgaris var. cicla) to varying water regimes [30%, 60% and 100% of crop water requirement (ETc)]. Field trials using a randomised complete block design, replicated three times, were conducted over two summer seasons, 2015/16 and 2016/17. Leaf number, plant height, chlorophyll content index (CCI), chlorophyll fluorescence (CF), and yield were measured in situ. For A. cruentus and C. olitorius, water stress (30% ETc) was shown to produce a lower yield, although leaf number, plant height and chlorophyll content index were unaffected, while for B. vulgaris, leaf number and yield were reduced by water stress. For V. unguiculata, CF, CCI, plant height, leaf number, and yield were not affected by water stress, indicating its suitability for production in water scarce environments. Using 60% ETc was suitable for the production of A. cruentus, C. olitorius and B. vulgaris var. cicla, whereas 30% ETc is recommended for V. unguiculata. The yield results of V. unguiculata indicate that it performs better, while the yield of A. cruentus and C. olitorius is comparable to that of B. vulgaris under similar conditions, indicating potential for marginal production.

Maize hybrids contrasting for drought tolerance differ during the vegetative stage. Drought is the main constraint on maize production in developing nations. Differences during development between genetic materials of maize grown under water restriction suggest that the plant can be improved with a view to its adaptation. In maize, sensitivity to water stress can occur at any stage of its phenological development. However, few studies report its effects on the vegetative phase of the cycle. On this basis, this study was conducted to examine how shoot and root-system indices are expressed in cultivation under water deficit as well as determine which indicators best explain the difference between hybrids in the evaluated water regimes. Commercial seeds of hybrids BR1055 and DKB-390 (drought-tolerant) and BRS1010 (drought-sensitive) were germinated in PVC tubes (1.0 m × 0.1 m) in a randomized complete block design, in a 3 × 2 factorial arrangement. The experiment was developed in a greenhouse where two water regimes were tested: no water stress and with water stress from the VE stage. The soil consisted of quartz sand mixed with a commercial fertilizer. Stem and root traits were evaluated up to the V5 growth stage. Relative chlorophyll content, leaf temperature, stem length, phenology, shoot dry biomass, root length, root dry biomass, root surface area, root volume and D95 were responsive to water deficit. The parameters that allowed the distinction between the hybrids in water the regimes were relative chlorophyll content, leaf temperature, phenology and average root diameter.

 RESUMO - O objetivo do trabalho foi avaliar o desempenho agronômico e econômico na cultura do milho verde submetida ao uso de bioestimulantes na presença e ausência de fungicida. Dessa forma, dois experimentos foram conduzidos em anos distintos, em delineamento experimental de blocos ao acaso com três repetições, em arranjo fatorial 4x2. O primeiro fator correspondeu à combinação de bioestimulantes (Ausência, MC Cream, MC Extra, MC Cream+MC Extra) e o segundo fator à presença e ausência de fungicida (piraclostrobina + epoxiconazole). Foi avaliado o peso de espigas verdes, a altura de plantas, diâmetro de colmo, teor de clorofila e severidade de doenças, além da viabilidade econômica dos tratamentos. Os Bioestimulantes, na ausência de fungicida, foram eficientes para aumentar o peso das espigas verdes, altura de plantas, e o teor de clorofila. Na presença do fungicida os bioestimulantes aumentaram o diâmetro de colmo e reduziram a severidade de doenças. Os investimentos em insumos elevaram os custos de produção, porém a rentabilidade foi compensada pelo aumento da renda bruta. Em situação de baixa disponibilidade hídrica, o bioestimulante MC Extra foi o mais viável economicamente para a cultura do milho verde.Palavras-chave: fitossanidade, produtividade, renda líquida, Zea mays L. EFFICIENCY OF BIOSTIMULANTS AND FUNGICIDE IN THE AGRONOMIC AND ECONOMIC CHARACTERS OF GREEN CORN  ABSTRACT – The objective of this work was to evaluate the agronomic and economic performance of the green corn crop, subjected to the use of biostimulants in the presence and absence of fungicide. Two experiments were conducted in different years using a randomized block design with three replications, in a 4x2 factorial arrangement. The first factor corresponded to the combination of biostimulants (Absence, MC Cream, MC Extra, MC Cream + MC Extra) and the second factor was the presence and absence of fungicide (pyraclostrobin + epoxiconazole). Green ear weight, plant height, stem diameter, chlorophyll content and severity of diseases were evaluated, as well as the economic viability of the treatments.In the absence of fungicide, biostimulants were efficient to increase the green ear weight, plant height, and chlorophyll content. In the presence of the fungicide, biostimulants increased stem diameter and reduced disease severity. Investments in inputs increased production costs, but profitability was offset by the increase in gross income. In a situation of low water availability, the biostimulant MC Extra was the most economically viable for the green maize crop.Keywords: plant health, productivity, net income, Zea mays L.

This study aims to determine the differences in the growth response of green curly lettuce to the differentiation treatment of LED lighting with different spectrum in indoor hydroponics. The research was conducted from October to November 2017. The experimental design used was experimental with 1 lighting factor with 5 levels, there are sunlight (P0), LED 20% blue: 80% red (P1), LED 80% blue: 20% red (P2), 50% blue LED: 50 % red (P3), and 100% white daylight (P4). Observational variables included plant height, leaf number, leaf area, leaf color, total wet weight, leaf wet weight, wet root weight and dry weight of the plant. The result of this experiment showed that LED irradiation have affect the treatment are plant height, leaf number, leaf area, chlorophyll content, fresh weight of harvest, root length, and dry weight of brackets. While those that have no significant effect are the wet weight of the roots. The results showed that between LED irradiation treatment L1, L2, L3, and L4 showed that treatment L2 with 80% blue spectrum composition: 20% red showed better growth based on: high plant, chlorophyll content, and root length. Treatment with L4 with white LED showed better growth based on the number of leaves, leaf area, fresh weight of harvest, root wet weight, and dry weight of total biomass. The results below the sunlight better than the LED irradiation treatment, because the intensity of LED far low and lack of controlled environmental conditions technology and management for growing lettuce. In all of LED treatment still looked etiolation because light intensity was not optimal yet.

Growing vegetable crops such as lettuce, on Ultisol soil has several obstacles, such as insufficient organic matter and nutrients in the soil. The provision of biochar and POC leri or organic fertilizer from rice washing liquid is expected to be a long-term and sustainable solution. This study was intended to test the addition of biochar to the growing media and the application of leri on lettuce cultivation. This study used a factorial Randomized Block Design (RAK) method. The first factor was the application of biochar to the planting medium (M), which consisted of M1: Ultisol without biochar and M2: Ultisol + 30 g biochar. The second factor was the administration of liquid organic fertilizer (LOF) leri (P), with 5 treatments consisting of P0: without giving LOF leri, P1: giving LOF leri without fermentation once a week, P2: giving LOF leri without fermentation twice a week, P3: giving fermented LOF leri once a week, P4: giving fermented LOF leri twice a week. The results of this study were tested statistically by analysis of variance, with the F test; if there was a significant difference, it was continued with the BNJ test (Honest Significant Difference) at a 0.05 level. The results showed that the best treatment of LOF leri in increasing lettuce growth and yield was 25% fermented LOF leri given 2 times a week, at 250 mL per lettuce plant. As a single treatment the best growing media was M2 (Ultisol soil + 30 g of biochar) with a plant height of 25.80 cm and the leaf number of 12.83; whereas the best LOF leri treatment was P4 (fermented LOF leri given twice a week), with a plant height of 30.27 cm and leaf number of 14.42. Based on whole plant fresh weight, the best treatment was the M2P4 (Ultisol + biochar growing medium and fermented LOF leri given week), which was 185.99 g per plant.

Water stress in sweet corn plants due effect of climatic events, such as El Niño, is difficult to monitor, leading to considerable losses. Silicon (Si) as an exogenous resistance elicitor may reduce water stress effects. The relationship between sweet corn plant age and its development, under induced water stress and leaf potassium silicate applications were evaluated. This work was carried out with the hybrid Tropical Plus®, in a randomized factorial block design with 15, 30, 45 and 60 kPa as soil water tensions in plots and potassium silicate doses (0, 6, 12 and 24 L ha-1) in subplots. Stem diameter, plant height and leaf number per plant were evaluated at 30, 45, 60, 75 and 90 days after seeding. Root length was measured on the 90th day after seeding. Sweet corn plants submitted to water stress conditions and Si application showed an age-dependent response. Water stress did not decrease stem diameter, plant height and number of leaves per plant sprayed with Si. Root length was longer with 60 kPa soil water tension. Silicon reduced negative impacts of water stress on sweet corn plants.
