The goal of this work was to evaluate the storage effects under different temperatures, relative humidities (RH) and packaging types on the seed physiological quality and pod moisture content of Arachis pintoi cv. BRS Mandobi. The fruit of this herbaceous, perennial, leguminous species consists of an indehiscent pod containing a single seed, which is not dehulled for planting purposes. Pod samples presenting an initial 5.8% moisture content and stored under atmospheres presenting 30, 50, 70, 80 and 90% RH at 21±2 °C reached, respectively, the following equilibrium moisture content (EMC): 5.1±0.3%, 6.2±0.2%, 7.4±0.3%, 8.5±0.2% and 11.6±0.4%. Pod components (pericarp and seed) differed from one another in terms of EMC when stored under the same RH?s; on an average, the pericarp EMC was 4.2% higher than that of the seed. A drastic physiological quality reduction was observed in seeds contained in pods that presented a 6.9% moisture content when storage temperature was raised from 21±2 °C to 30±3 °C. The physiological quality of seeds was preserved for a longer time in semi-permeable packages; this contributed either to maintain low EMC?s or to delay reaching higher pod EMC?s, depending on the RH under which they were stored. |

Crop rotation associated with the use of cover crops promotes the introduction of crop residues to the soil, with direct and indirect effects on theavailability of plant nutrients, especially nitrogen (N). The objectivesof this study wereto estimate the N utilization from15N-ureaand cover crop residues (labelled with 15N)of maizecropsgrown in succession,andevaluate the effectsof the isolated and combined use of cover crops and urea on maize plant height, yield components,andgrain yield, grownunderano-tillage system. Field researchwas conductedin anOxisol (Rhodic Haplustox), Cerrado (Savannah) phase. The experimental design was a randomized block with 20 treatments and four replications in a 5x4 factorial scheme. The treatments were four cover cropsspecies: sunnhemp (Crotalaria juncea L.), pigeon pea (Cajanus cajan(L.) Millsp), green velvetbean (Mucuna prurens),and millet (Pennisetum glaucumL.) + spontaneous vegetation (fallow in the off-season),combined with four N rates: 0, 30, 90,and 150 kg ha-1, applied at the sowing and topdressingstages. The results showed that legume covercropsprovided maize grain yieldsequivalent tothe applicationof 80-108 kg ha-1N as urea. TheureaN utilizationby the maize was at an averageof43.5% of the appliedamount.The results indicatethat cover crops, particularly legume cover crops,are an important source of N to non-legume cereals.Legumes used as cover crops can replace nitrogen fertilizers of more than 80 kg ha, which is both environmentally and economically viable for corn production.
