The aim of this work was to characterize the spatial variability of the atributes of soil and plants in severely-eroded areas. The experimental plot had dimensions of 45 by 65 m, and was divided up into a grid with regular spacing of 5 m between points, making up a rectangle of 10 columns and 14 lines, totaling 140 points. The contents of macro and micronutrients were determined in the plants, plus dry mater and height of the Crotalaria juncea. The atributes of plants and soil thickness were distributed over the area in a well-defned spatial structure, with an adjustment of the spherical and Gaussian models, making an exception for calcium. Soil thickness demonstrated the locations with an accelerated process of erosion and displayed a clear spatial relationship with plant height and dry mater of the C. juncea and with the foliar macro and micronutrients.
O objetivo desse trabalho foi caracterizar a variabilidade espacial de atributos de solo e de plantas em áreas severamente erodidas. A parcela experimental teve a dimensão de 45 por 65 m e foi dividida em uma malha com espaçamento regular de 5 m entre pontos, sendo um retângulo de 10 colunas e 14 linhas, totalizando 140 pontos. Foram determinados os teores de macro e micronutrientes nas plantas, matéria seca e altura da Crotalaria juncea L. Os atributos das plantas e a espessura do solo distribuem-se na área em estudo com uma estrutura espacial bem definida, com ajuste dos modelos esférico e gaussiano com exceção para o cálcio. A espessura do solo demonstrou os locais com o processo de erosão acelerado e apresentou forte relação espacial com a altura de planta e matéria seca da C. juncea e, com os macros e micronutrientes foliares.

The economics of coffee plantations is intrinsically linked to pruning, which can improve the canopy architecture and thereby increase productivity. However, recommended pruning times on conilon coffee plantations have been made on an entirely empirical basis. In this study, by evaluating growth, photosynthetic gas exchanges, starch accumulation and crop productivity, the effects of pruning at different times between harvest and flowering were investigated for six conilon coffee clones with distinct stages of fruit maturation (early, intermediate and late). Clones with an early maturation stage were pruned at four different times: 0, 30, 60 and 90 days after harvest (DAH). Intermediate clones were pruned at 0, 30 and 60 DAH, and late clones were pruned at 0 and 30 DAH. Overall, the rates of shoot growth and net photosynthesis, the stomatal conductance and the crop yield were not affected by the pruning treatments in any of the clones. In addition, pruning times did not affect the concentrations of starch or the photochemical efficiency of photosystem II. The carbon isotope composition ratio was marginally affected by the treatments. These results suggest that the pruning time after harvests is relatively unimportant and pruning operations can be scheduled to optimise the use of labour, which directly impacts the production costs of coffee. |
