Desenvolvimento Inicial de Plantas de Eucalyptus Platyphylla Submetidas A Níveis de Salinidade

The objective of this study was to evaluate the behavior of morphological Eucalyptus platyphylla when subjected to five levels of soil salinity. The research project was conducted in a greenhouse at the experimental area of the Department of Agricultural Engineering of the FCA / UNESP, Botucatu-SP, utilizing plastic pots filled with soil containing NaCl concentrations, in sufficient quantities to raise the level of electrical conductivity. The experiment was conducted in randomized blocks in factorial scheme 5 x 4, 5 electrical conductivities (1.41, 2.50, 4.50, 6.45 and 8.33 dS m-1) and four repetitions. The results showed that soil salinity did not significantly affect the following parameters: height, green mass and dry matter of shoot, and root and leaf area of the plants.

Resposta da alface à aplicação de biofertilizante sob dois níveis de irrigação

The use of biofertilizers is interesting for agriculture as being an economical alternative as well as it is environmentally friendly by using organic waste and reducing the application of mineral fertilizers. The aim of this study was to evaluate the effect of biofertilizer doses of bovine origin (biodigester effluent) applied on the ground and two levels of irrigation on lettuce. The experiment was conducted under protection of a greenhouse in pots, applying to the soil different doses of biofertilizer of bovine origin obtained from anaerobic reactor (10, 20, 40 and 60 m3 ha-1) and mineral fertilizer as a witness in two irrigation levels calculated at 50 and 100% of reference evapotranspiration. The lettuce plants were analyzed in their: Height, leaves number, crown diameter, fresh weight and dry weight of shoots. The biofertilizer treatments showed better results than the mineral fertilizer and has increased with increasing doses of biofertilizer, the highest dose (60 m3 ha-1) showed the best results in all variables. For dry, mineral fertilization showed higher values. The irrigation levels had no effect on plant growth.

Efeito do manejo e de níveis de lodo de esgoto na fertilidade do solo após tres aplicações

The agricultural use of sewage sludge as organic fertilizer is considered nowadays as on alternative of disposal, in the end of the residue in addition to possible environmental problems, it's using can decrease the mineral fertilizers and avoid provide organic matter to the soil. The objective of this study it was to evaluate the parameters of soil fertility under different managements and doses of sewage sludge after the third application of the residue. The experiment was carried out in São Manuel - SP, with the cultivation of sunflower in two consecutives cycles, followed by wheat and triticale without application of the residual, and in the following year with the application of sewage sludge and cultivated the black oats. It was adopted a randomized complete block design, consisting of six treatments and five repetitions defined as follows: T0 - without fertilization; T1 - mineral fertilizer nitrogen according to crop need, T2 - 50% of N from sewage sludge and 50% in mineral form, T3 - 100% of N from sewage sludge, T4 - 150% of N from sewage sludge, T5 - 200% of N derived from sewage sludge. Soil samples were collected in the end of the trial of oats. There were an increase in the levels of P, H + Al, CEC and OM, B, Cu, Fe, Mn, Zn as a function of increasing dose of sewage sludge. To V% and pH were decreased the values in the proportional soil to the increase of sludge dose until 24 and 22 t ha-1, respectively and after increasing the pH and V%.

Características agronômicas do feijão caupi inoculado em função de lâminas de irrigação e de níveis de nitrogênio

The aim of this study was to evaluate the effect of different irrigation depths and nitrogen levels on the agronomic characteristics of inoculated cowpea. The experiment was arranged in splitplots, with the levels of nitrogen in the plots and the depth of irrigation in the splitplots, in a randomized block design, with two repetitions. The irrigation depth corresponded to 578 mm (L1), 512 mm (L2), 429 mm (L3), 299 mm (L4) and 240 mm (L5), and the nitrogen levels of 0, 30, 60 and 90 kg ha-1 of N. The nitrogen levels showed significant effect on the yield components of cowpea. The irrigation depth showed significant effects on productivity of bean cowpea, with the depth of 426.21 mm estimated for obtaining the maximum productivity of 2820.03 kg ha-1.
