Aims: The study aimed to investigate the physiological behaviour of cupuaçu tree progenies subjected to water deficiency; Study Design: The experimental design was completely randomised, in a 2x7 factorial scheme (2 water regimes: with and without water deficiency and 7 cupuaçu tree genotypes), totalling 14 treatments with 5 replications; Place and Duration of Study: The experiment was carried out from March to November 2016, in a greenhouse of Embrapa Eastern Amazon in the municipality of Belém, State of Pará, Brazil, located at the geographic coordinates 01º 27' of South Latitude and 48º 30' of West Longitude; Methodology: The following parameters were evaluated: predawn water potential (Ψpd), water potential of xylem (Ψx), stomatal conductance (GS), transpiration (E), photosynthesis (PS), internal carbon concentration (CI), internal and external carbon ratio (CI/CA), chlorophyll a (Chl a), b (Chl b), total (Chl total), anthocyanin (ANT), carotenoids (CAR), instantaneous carboxylation efficiency (ICE), and water-use efficiency (WUE). The variables were submitted to multivariate analysis; Results: Two distinct groups were resulted. Group 1 retained the treatments with water deficiency and group 2 retained the control treatments. This result occurred because the water conditions were different. The MC1 was influenced by PS because photosynthetic pigments are essential for photosynthesis. PS, GS, Chl total, Chl a, CAR, CI, CI/CA, Ψpd, Ψx, E, and ICEresulted with greater intensity in the control treatments, and with less intensity in the genotypes submitted to water deficiency; This behaviour is because of water deficiency that reduces photosynthesis. The MC2 was influenced by Chl b, ANT, and WUE. In water deficiency, the distinction in the physiological behaviour of cupuaçu tree progenies occurs in relation to the progenies that did not undergo water stress; Conclusion: The cupuaçu tree progenies under water restriction condition have a positive effect on water-use efficiency.

Composting is a useful way of transforming livestock waste into organic fertilizer, which is proven to increase soil nutrient levels, and thus crop yield. Remains from production and slaughter of small ruminants can become a source of important elements for plant growth, such as N, after microorganism-driven decomposition.The aim of this investigation was to evaluate the effects of this compost on soil fertility and on the nutritional status and yield of the corn crop. The experiment was conducted in a Haplic Luvisol in a randomized block design with six treatments and five application rates of the organic compound in Mg ha-1: 3 (half the standard rate), 6 (standard rate), 9 (one and a half times the standard rate), 12 (twice the standard rate), and 24 (four times the standard rate) and an additional treatment with mineral fertilizers (110, 50 e 30 kg ha-1 of N, P2O5 and K2O, respectively), with four blocks. Evaluations were performed for two harvests of rainfed crops, measuring soil fertility, nutritional status, and grain yield. The compost increased P, K, Na and Zn values in the 0.00-0.20 m layer in relation of mineral fertilization in 616, 21, 114 and 90 % with rate 24 Mg ha-1 in second crop. Leaf N, Mg, and S contents, relative chlorophyll content, and the productivity of corn kernels increased in 27, 32, 36, 20 e 85 %, respectively, of low rate (3 Mg ha-1) to high rate (24 Mg ha-1) with of application of the compost. Corn yield was higher with application of organic compost in rate of 24 Mg ha-1 than mineral fertilizer combination in second crop.
