Initial height of pasture deferred and utilized in winter and tillering dynamics of signal grass during the following spring

Tillering dynamics during regrowth in the spring (September to December 2009) on signal grass (Brachiaria decumbens cv. Basilisk) pastures deferred in the beginning of April 2009 is evaluated. Four pasture heights were evaluated at the beginning of deferment (10, 20, 30 and 40 cm). The experimental design consisted of completely randomized blocks with two replications. Rise in pasture height at the beginning of deferment decreased the appearance rate, increased the mortality rate and reduced the survival rate, the balance between appearance and mortality and the stability index of the tiller population at the beginning of the spring. Pastures deferred at initial height of 30 and 40 cm presented relatively stable tiller appearance rate between the beginning and end of spring. However, these pastures presented greater mortality rate, lower survival rate, lower balance between appearance and mortality and lower stability index of the tiller population at the beginning of spring when compared to rates at the end of spring. Pastures managed with shorter initial heights (10 and 20 cm) provided more tissue renewal in the subsequent growth season after their utilization in the winter.

Bactérias promotoras de crescimento e adubação nitrogenada no crescimento inicial de cana-de-açúcar proveniente de mudas pré-brotadas

The objective of this work was to evaluate the effects of the inoculation with plant growth-promoting bacteria on the formation of sugarcane pre-sprouted seedlings, originated from individual buds, and to quantify the initial growth of these seedlings in association with nitrogen application, in a low fertility soil. Two experiments were carried out: one in greenhouse conditions, with a time span of 50 days, and the other in vases under field conditions, with a time span of 180 days. In both experiments, a randomized complete block design was used with a factorial arrangement of 2x3, in the first experiment - with or without inoculation, and with three quantities of bud reserve -, and of 2x2x4, in the second one - with or without inoculation, with or without nitrogen, evaluated in four times: at 45, 90, 135, and 180 days. The inoculant had effect on the initial growth of the pre-sprouted seedlings, increasing sprouting speed and dry matter accumulation on roots and shoots, regardless of the bud reserve amount. In the second experiment, the inoculant increased the initial growth of shoots and root system up to 180 days after transplantation, increasing height, tillering, stalk diameter, dry matter production of stalks and straw, and root length, regardless of nitrogen application. The inoculant has a positive physiological effect on plant growth.
