The aim of this study was to analyze the effects of molybdenum and inoculant application via seed treatment in soybean, and their role in the nitrate reductase enzyme activity, agronomic traits and physiological quality of the produced seeds. The experiment was conducted at the Federal University of Pelotas (UFPel), Rio Grande do Sul state, Brazil. The treatments were shaped by five doses of molybdenum (zero; 16; 32; 48; 64 g.100kg-1 of seeds) combined with the presence and absence of liquid inoculant (Bradyrhizobium japonicum), at a dose of 200 mL per 100 kg of seeds. The evaluations of nitrate reductase activity, agronomic traits and physiological seed quality were performed in the present work. The measured agronomic traits were: plant height, number of pods per plant, number of seed per plant and thousand-seed weight. Standard germination test was executed to evaluate the produced seed viability. First germination counting, accelerated aging test, cold test, plantlet shoot and root length, plantlet shoot and root dry mass, and field seedling emergence were utilized to measure the seed vigour. Molybdenum, both in presence and absence of inoculant, positively influenced the enzymatic activity, for both vegetative and reproductive stages. The addition of inoculant and molybdenum provided increase in the vigour of the produced seeds. The enzyme activity was positively correlated with the agronomic traits and vigour tests. The addition of inoculant and molybdenum in the seed treatment provides a better expression of nitrate reductase activity and vigour of the produced seeds.

“…This fact happened, possibly, due to the 30 DAE, the plant was in the period of flowering. The flowering period corresponds to the period of maximum nodulation, in other words, occurs at 30 DAE an establishment of the number of nodules, mainly in the main root, reflecting directly in its fresh and dry mass [22]. According to the results shown in Table 7, it can be verified that the residual dose of 80 kg·ha −1 of P 2 O 5 promoted higher number of pods per plant (NPP), but did not differ from the other doses, except for the control treatment.…”

Phosphate fertilizers when applied to the soil, besides being harvested by the crops, promote a residual effect that can be offered to subsequent crops. The objective of this research was to evaluate the residual effect of phosphate fertilization applied to maize cultivation on the successor crop, cowpea, in the Cerrado region in Maranhao. The research was carried out in the experimental area of Federal University of Maranhão (UFMA), located in the city of Chapadinha, MA (3˚44'30"S, 43˚21'37''W). The experimental design was in randomized blocks, with six treatments and four replications. The treatments were composed of the following residual P doses: 0, 60, 70, 80, 90, 100 kg·ha ) and a greater profit margin (US $326.26). Thus, it is feasible to grow cowpea in previously cultivated areas, in order to take advantage of residual phosphate fertilization.

“…Esta variable ha mostrado respuestas diferentes a la aplicación de Co y Mo en varias investigaciones. Por ejemplo, Milani et al (2008) en un estudio de fertilización foliar con Mo en soja, observaron que la altura de plantas varió significativamente entre los diferentes tratamientos aplicados. En contraste, Meschede et al (2004) no encontraron diferencias significativas para esta variable cuando aplicaron Mo y Co vía tratamiento de semillas y fertilización foliar.…”
