Aims: The objective of this work was to evaluate the effect of nitrogen fertilization on the production of Tamarindus indica L. seedlings irrigated with saline water. Study Design:  A randomized complete block design was used in a 4 x 4 factorial scheme, whose factors were the electrical conductivity levels of the irrigation water. Place and Duration of Study: The work was conducted under protected environment conditions (greenhouse) at the Federal University of Campina Grande, Center for Agro-Food Sciences and Technology, Campus of Pombal-PB, Brazil, in the period from January and March 2017. Methodology: Effects of doses of 0, 100, 200 and 300 mg of nitrogen (N) dm-3 and electrical conductivity levels of the irrigation water (ECw) (0.3, 2.1, 3.7 and 5.2 dS m-1) on growth of Tamarindus indica L. have been studied. Results: The growth of the seedlings was reduced by the increase of the electrical conductivity of the irrigation water, however, irrigation with ECw water of 2.15 dS m-1, promotes acceptable reductions of 10% in the morphology of the tamarind tree. Conclusion: The use of nitrogen fertilization with urea did not attenuate the deleterious effects of irrigation water salinity or promoted improvements of the quality of the tamarind seedlings.

ABSTRACT The objective of this work was to evaluate the growth of sugar-apple seedlings under irrigation management with saline water in a substrate with soil amendment. Treatments were obtained from the arrangement between polymer doses (0, 0.2, 0.6, 1.0 and 1.2 g dm-3) and levels of irrigation water electrical conductivity (0.3, 1.1, 2.7, 4.3 and 5.0 dS m-1), associated with irrigation frequencies (daily and every alternate day), and two additional treatments to evaluate container volume (1.30 and 0.75 dm3), using a randomized complete block design, with four replicates. At 120 days after sowing, the variables substrate salinity, stem diameter, plant height, number of leaves and Dickson quality index were determined. Data were submitted to analyses of variance, regression and contrast. Substrate salinity increased with the increase in irrigation water electrical conductivity and polymer doses. Growth and quality of the seedlings were reduced with increasing irrigation water salinity, and highest values of the variables were obtained in seedlings under daily irrigation. Container with larger volume led to higher growth. The use of hydrated polymer at the adopted levels had no effect on growth and quality of seedlings, requiring further studies. To produce sugar-apple seedlings with better quality, irrigation frequency should be daily and water electrical conductivity should be lower than 2 dS m-1.

Abstract Most potato farmers in Indonesia select the small tubers at harvest for planting in the following season, the so-called farmers’ practice (FP). This propagation method is cheap, but the small tubers may come from less healthy plants, which increases the build-up of diseases with accelerated yield decreases over the seasons. Alternatively, farmers may identify healthy plants within the growing season and select those for propagation, the so-called positive plant selection method (PPSM). An experiment was carried out to evaluate the effects of PPSM compared to FP on yields in the following season in the two main potato growing areas of West Java, i.e., Pangalengan and Garut. Generations G2 and G3 of cv. Granola and one generation of the imported cv. Atlantic were used. Selected seeds using PPSM and FP were planted in the second season in a randomized complete block design. Results show that yields of seeds selected through PPSM were significantly higher compared to seeds selected through FP, over both locations, on average, 7.4, 5.5 and 1.2 ton ha−1 for Granola G2 and G3, and the Atlantic, respectively. These yield increases represent an increase in the gross revenue of 30.8 to 51.8 million IDR ha−1 for Granola and 1.9 to 7.8 million IDR ha−1 for Atlantic at a farm gate price of 7,000 and 6,500 IDR kg−1, respectively. This study confirms that PPSM is superior to FP and improves the quality of the farms saved seeds.

Culture Development

Vegetable development and productivity are influenced by several factors, including the nutrient amounts available. Providing adequate nitrogen favours vegetative growth and promotes increased productivity, in addition to providing greater succulence and improving leaf quality. This work evaluated the effect of nitrogen doses and sources on arugula culture development and productivity. The experiment was conducted on the experimental farm at the State University of Goiás, Ipameri campus, in the municipality of Ipameri, Goiás state (GO). The experiment used a 2 × 5 factorial randomized complete block design, with two sources (normal urea and coated urea), five nitrogen doses (0, 60, 120, 180 and 240 kg ha-1 of N) and four replicates. Plant height, stem diameter, leaf number, fresh shoot matter, dry shoot matter and productivity were evaluated. The results obtained here suggest that nitrogen sources do not influence arugula culture development, but nitrogen doses influence the arugula culture’s productive characteristics.

ABSTRACT The salinity of water and soil reduces the growth and production of crops, especially the fruit trees, such as papaya. Thus, it is necessary to obtain management alternatives for cultivation under these conditions. Therefore, the objective of this study was to evaluate the growth and phytomass of papaya cultivated under irrigation with saline water and organic fertilization. An experiment was set up using a randomized block design, with the treatments distributed in a 5 x 2 factorial scheme, consisting of five levels of salinity of irrigation water (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and two levels of organic fertilization (10 and 20 L of bovine manure per plant), with three replications, totaling thirty experimental plots. Growth variables of papaya were evaluated. Papaya plants were negatively affected by irrigation water salinity, with a greater effect on the number of leaves and on dry phytomass of leaves, with no effect of bovine manure levels.
