[email protected]     1 RESUMO   O ajuste de estratégias de adubação aliadas ao manejo racional da irrigação para o uso sustentável da água na produção de tomateiro destinado ao processamento industrial pode contribuir com a cultura do tomate. Avaliou-se a influência da adubação organomineral e de lâminas de reposição deficitária aplicadas via gotejamento sobre o crescimento e a produtividade do tomateiro industrial. Conduziu-se um experimento em campo utilizando a cultivar de tomateiro industrial BRS Sena. Utilizou-se delineamento experimental de blocos completos casualizados, em esquema fatorial (4 x 2), sendo quatro lâminas de irrigação (55, 70, 85 e 100% da ETC) e fertilizantes (organomineral e mineral). A irrigação utilizada foi por gotejamento e realizada diariamente de acordo com a evapotranspiração de referência (ET0). Avaliou-se: altura de plantas, diâmetro do caule, número de ramos laterais, número de frutos por planta, produtividade, produção de frutos planta-1, percentual de frutos defeituosos, massa fresca frutos defeituosos, percentual de podridão mole nos frutos, percentual de lóculos abertos, percentual de escaldadura nos frutos, percentual de broca grande nos frutos, percentual de podridão apical nos frutos, diâmetro longitudinal médio, diâmetro equatorial médio, sólidos solúveis totais, massa fresca de frutos e massa seca de frutos. A aplicação de fertilizante organomineral proporcionou maior produção de frutos por planta e maior diâmetro de frutos. As características biométricas correlacionaram-se entre si. A produção de frutos por planta e a produtividade aumentam linearmente com o incremento da taxa de reposição da evapotranspiração diária do tomateiro.   Palavras-chave: Solanum lycopersicum L., organomineral, reposição de água deficitária, manejo da irrigação ALMEIDA, M.

REPLENISHMENT OF WATER AND FERTILIZATION WITH ORGANO-MINERAL IN THE GROWTH AND PRODUCTION OF INDUSTRIAL TOMATO.     2 ABSTRACT   The adjustment of fertilization management strategies associated with the rational management of irrigation for the sustainable use of water in the production of tomato destined for industrial processing can contribute to tomato crops. The objective of this study was to evaluate the influence of organomineral fertilization and replacement of deficient depths applied by drip irrigation on the growth and yield of industrial tomato. An experiment was conducted in field using BRS Sena industrial tomato cultivar. A randomized complete experimental block design was used in a factorial scheme (4 x 2), with four irrigation depths (55, 70, 85 and 100% ETC) and fertilizers (organomineral and mineral). The irrigation used was by drip system and performed daily according to the reference evapotranspiration (ET0). The following items were assessed: plant height, stem diameter, number of lateral branches, number of fruits per plant, productivity, plant-1 fruit production, percentage of defective fruits, fresh mass defective fruits, percentage of soft rot in fruits, percentage of open lobes, percentage of fruit scald, percentage of large fruit borer, percentage of apical rot in fruits, average longitudinal diameter, average equatorial diameter, total soluble solids, fresh fruit mass and dry fruit mass. The application of organomineral fertilizer resulted in higher production and diameter of fruits per plant. Biometric characteristics correlated with each other. Fruit production per plant and productivity increased linearly with the increase in the replacement rate of daily evapotranspiration of tomato.   Keywords: Solanum lycopersicum L., organo-mineral, deficit water replacement, irrigation management

The objective of this study was to evaluate the productivity and quality of melon fruits as a function of the dose and time of application of biostimulant in the conditions of the semi-arid region of Paraíba. The experiment was carried out at the Federal University of Campina Grande, campus of Pombal - PB, Brazil, in a randomized block design in a 4 x 5 split plot scheme, with doses of biostimulant (0; 0.5; 1.0; 1, 5 and 2.0 L ha-1) and in the subset of the biostimulant application times (15; 20; 25 and 30 days before harvest - DAC), in four replications. Characteristics related to fruit production and quality were evaluated. There was no interaction between the factors of dose and application time of the biostimulant in any of the evaluated characteristics. Thus, the highest estimated values of number of fruits per plant, fruit mass and total melon production were obtained with the application of doses ranging from 0.9 to 1.5 L ha-1 and at the time of application it varied from 22,5 to 23.6 DAC. The content of soluble solids increased 5.5% when the biostimulant dose of 2.0 L ha-1 was used and 4.4% when the product was applied 15 days before harvest.

Irrigation associated to reduction on planting spaces between rows and between coffee plants has been a featured practice in coffee cultivation. The objective of the present study was to assess, over a period of five consecutive years, influence of different irrigation management regimes and planting densities on growth and bean yield of Coffea arabica L.. The treatments consisted of four irrigation regimes: climatologic water balance, irrigation when the soil water tension reached values close to 20 and 60 kPa; and a control that was not irrigated. The treatments were distributed randomly in five planting densities: 2,500, 3,333, 5,000, 10,000 and 20,000 plants ha-1. A split-plot in randomized block design was used with four replications. Irrigation promoted better growth of coffee plants and increased yield that varied in function of the plant density per area. For densities from 10,000 to 20,000 plants ha-1, regardless of the used irrigation management, mean yield increases were over 49.6% compared to the non-irrigated crop.

Among the problems faced by the melon crop in the state of Rio Grande do Norte, northeastern Brazil, the effect of water and soil salinity is considered one of the key factors to limit fruit production and quality. The aim of this work was to study the effects of using irrigation waters with different salinity levels on yield and quality of fruits of the yellow melon hybrid Mandacaru. A randomized complete block design was used with five treatments (irrigation water salt concentrations: 0.54, 1.48, 2.02, 3.03, 3.9 dS m-1) and four replications. The effects of these concentrations were evaluated through, number of marketable fruits per plant, marketable and total fruit yield, average marketable fruit mass, soluble solids content and pulp firmness. Increment in water salinity level negatively influenced crop yield. The 3.9 dS m-1 salinity level caused yield losses of 20.31%, due to the reduction of fruit number per plant. The highest soluble solid content and the highest pulp firmness values were estimated to occur at salinity levels 2.09 and 3.5 dS m-1, respectively.

Drip irrigation technique has proved its superiority over other methods of irrigation due to direct application of water and nutrient in the vicinity of root zone. A field study was conducted to evaluate the effect of irrigation and fertigation scheduling through drip irrigation in tomato (Solanum lycopersicum L.) during Rabi season of 2015-16 at Rajasthan College of Agriculture, MPUAT, Udaipur. There were three irrigation levels and five fertilization levels in split-plot design with three replications. Nutrient content in plant and fruit was found higher under the application of drip irrigation at 100 % PE (I1) and at 100 % RDF through fertigation (F1). Maximum nutrient uptake by tomato i.e. nitrogen (166.83 kg ha-1), phosphorus (41.59 kg ha-1) and potassium (183.08 kg ha-1) was recorded with treatment combination of drip irrigation at 75 % PE (I2) + 75 % RDF through fertigation + 2 foliar spray of 1 % urea phosphate (F3). Similarly, significantly maximum yield and growth attributes i.e. fruit yield (201.25 q ha-1), plant height (67.43 cm) and number of branches (12.33) were registered with treatment combination of drip irrigation at 75 % PE and 75 % RDF through fertigation + 2 foliar spray of 1 % urea phosphate. Drip fertigation method has proved to be very significant in improving nutrient uptake which finally resulting in enhancement of growth and yield of tomato crop.

Solanum Lycopersicum L

Tomato (Solanum lycopersicum L.) is a broadly consumed fruit vegetable globally. It is one of the research mandate vegetable of the National Horticultural Research Institute (NIHORT), Ibadan, Nigeria. The institute’s contains diverse collections of tomato accessions and wild relatives, without utilization information for the African continent. With the decline in diversity and potential of cultivars, a robust tomato breeding pipeline with broad genetic base that eliminates redundancy in the development of lines with desired horticultural traits is paramount. This study evaluated the mean performance and variations of thirteen wild tomato accessions obtained from the C.M. Rick Tomato Genetic Resource Center, University of California, Davis, USA, evaluated for agronomic, nutritional and physicochemical traits under a rain forest zone in Nigeria. The accessions were planted and grown in three replications with randomized complete block design. Agronomic traits, physicochemical and nutritional parameters were measured and analyzed. There was significant (P < 0.001) variation among accessions for all traits measured. Accession LA0130 was separated from others by cluster analysis and was outstanding for its unique attributes which include: fruit yield parameters, total soluble solids, acidity and content. The principal component analysis suggests fruit yield related traits, acidity and contributed most to the variation among the 13 accessions. The results obtained can be used to breed materials adapted to a rain forest . These wild tomato accessions have genes with desirable agronomic, nutritional and physicochemical traits that could be into breeding lines to improve commercial tomato varieties.

Irrigation management associated with other banana agricultural practices can provide an increased productivity and improved fruit quality. This study assessed the productive characteristics of banana genotypes under different irrigation water depths. The experiment was conducted at the experimental area of the School of Agronomy (EA/UFG) in Goiânia, GO, Brazil. The experimental design was a split-plot randomized block design, in which four irrigation water depths (30, 65, 100, and 135% of crop potential evapotranspiration, ETpc) composed the plots and three genotypes (‘FHIA 18’, ‘Grande-Naine’, and ‘Prata’) the subplots, with a spacing of 2.5 × 1.6 m. During the experimental period (first production cycle), the total precipitation was 1719.20 mm. Characterization of genotype development and yield was performed with the following assessments: bunch mass (kg), number of hands, stalk mass (kg), fruit diameter of the second hand (mm), fruit length of the second hand (cm), mass of the second hand (kg), number of fruits of the second hand, total number of fruits, and number of damaged fruits. The cultivar ‘FHIA 18’, differently from the others, showed a significant response to irrigation water depths on productivity. In the genotypes ‘Grande-Naine’ and ‘Prata’, an influence of irrigation was observed only on external and visual characteristics of fruit (diameter, length, and number of damaged fruits). In the genotype ‘Prata’, the irrigation water depth of 965 mm allowed fruit production with a larger diameter. Fruit length in the genotype ‘Prata’ increased linearly as water depth increased. The use of irrigation promoted a reduction in the number of damaged fruits in the genotypes ‘FHIA 18’ and ‘Grande-Naine’.

This experiment was conducted to study the effect of irrigation intervals on growth, yield and its components and some of the chemical characteristics of the soil after the harvest of quinoa (Chenopodium quinoa willd) plant. Three treatments were used as follow: T1 (twice irrigation every week, which is the common in the region), T2 (once irrigation every week) and T3 (twice irrigation every two weeks) using in a randomized complete block design with four replicates. The crop coefficient (Kc) value differed according to the stage of growth where the results showed that the T2 treatment gave the highest mean in all the studied traits followed by the T3 treatment in all traits except the number of seed/m2. The results also confirmed that the increase in water reduced the agronomic traits such as harvest index, number of seeds and yield of seeds and straw/m2. Also it showed that the pH values in soils were not significantly affected by irrigation, while Ec significantly affected. Correlation coefficient was negative with the most traits and low with the number of grain (0.34) under overall studied treatments which confirms that quinoa is a plant that needs limited amounts of irrigation water. On the other hand there was positive strong correlation between the harvest index and grain yield (0.92). The results showed that moisture stress treatments increased the concentration of the ionic, NH4-N and NO3-N significantly compared to soils which do not have moisture stress (T1, T2). We assume that the development based on Kc during growth-stages helps in irrigation management and provides precise water applications for quinoa plant. These results indicate that the water requirements of quinoa plant are limited and that quinoa plant growth is not affected by the lack of irrigation water on the crop and its qualities.

Tomato (Solanum lycopersicum L.) is an important vegetable in the country which is consumed both raw and as processed product. This study aimed to evaluate the growth, yield, postharvest qualities and profitability of aquaponically grown tomato supplemented with different nutrient solutions. The study was laid out in Randomized Complete Block Design with 8 treatments replicated 3 times. Tomato fruits were first harvested 60 days after transplanting with 100 percent survival rate. Early flowering of tomato plant was observed when applied with VSU liquid nutrient formulation (VSU-LNF) with node number ranging from 13.33-14.00 bearing the first flower. Growth parameters such as plant height, number of lateral shoot, root length and fruit size are stimulated by the application of VSU liquid nutrient formulation and in combination with ferments. This also resulted to high number and weight of marketable fruit in tomato plant. Carotenoid and chlorophyll contents of the fruits were higher in aquaponically grown tomato supplemented with fermented kuhol (Pomacea canaliculata L.). Free radical scavenging activity was found highest in the fruit of tomato grown in aquaponic system supplemented with combined VSU liquid nutrient formulation with fermented malunggay (Moringa olifera). However, vitamin Cand sugar content of tomato fruits were found highest when supplemented with combine VSU liquid nutrient formulation and fermented kuhol. No significant differences were obtained on firmness, percent weight loss, respiration rate at 2 and 4 weeks after storage, titratable acidity, fruit nitrogen, pH of fruit, oxidation reduction potential, electrical conductivity and total dissolved solids. On the other hand, higher moisture content of the tomato fruits were observed with the application of VSU liquid nutrient formulation and in combination with ferments. Therefore, high yield was produced with the application of VSU liquid nutrient formulation which resulted to higher net return. Aquaponically grown tomato supplemented with VSU-LNF produced lesser yield but with considerable net return.
