“…The use of TSE as irrigation water is a promising alternative to meet the water and nutritional demand of plants (Gonçalves et al 2017). It can completely eliminate the need for nitrogen fertilization, as well as the majority of potassium fertilization in crops, which leads to greater yield than that with mineral fertilization (Fortes Neto et al 2013;Santos et al 2017a). The application of TSE increases soil fertility (Rosa et al 2017), and does not detract it from its physical properties (Andrews et al 2016), especially in regions with high crop yield due to humid climates.…”

maximum leaf area index (LAI), panicles per square meter, number of grains per panicle, grain mass, grain yield (GY), and biomass yield (BY). In order to define the NDVI critical limits, NDVI values were generated as a function of relative BY in four phenological stages; NDVI values at 90% and 110% of relative BY were considered critical. Maximum GY (5.775 kg.ha-1) and BY (20,731 kg.ha-1) of white oats were achieved with TSE-induced nitrogen rates of 45 kg.ha-1 and 88 kg.ha-1 , respectively. NDVI readings were highly correlated (greater than 0.85) with growth and yield of white oats. In this study, we defined the critical NDVI limits of white oats and obtained maximum precision at the phenological stage 10.5.4.

The present study aimed to evaluate the residual effects of the application of biofertilizer and mineral fertilizer on sward structure and morphological components of Panicum maximum cv. Massai. The experimental design comprised randomized blocks with six treatments consisting of increasing doses of swine biofertilizer (0, 10, 20, 30 and 40 Mg ha-1) and mineral fertilization (150 kg N ha-1, 33 kg P ha-1), with four replicates. The variables analyzed were pasture height, light interception, leaf area index, forage mass and morphological components. Plant height responded linearly and positively to biofertilizer levels in the three evaluations. The highest averages for light interception (51.63%) and leaf area index (1.64) were observed for the 240 days (40 Mg ha-1). Dry leaf mass was influenced by the increase in biofertilizer dose, with increments of 39.68%, 25.07% and 44.66% for the 240, 300 and 360 days, respectively, when compared to the control treatment. Mineral fertilization promoted lower mass of dead material and lower leaf area index but did not differ from biofertilizer for the other variables. The residual effect of swine biofertilizer was greater than that of mineral fertilization, with a minimum use of 20 Mg ha-1 a practical agronomic recommendation.

Because of climatic problems in the Brazilian semi-arid region, it is of fundamental importance to seek a culture that considers water scarcity and available natural resources. Thus, a randomized block design, with subdivided plots and six replications, was carried out in the experimental area of the treatment and wastewater reuse station of the Milagres Settlement, Apodi, Brazil, with the objective of evaluating cultivation of herbaceous cotton (Gossipyum hirsutum) fertigated with domestic sewage treated in a semi-arid environment. Two cultivation cycles were carried out, and the cotton plants were fed with three different solutions containing treated domestic sewage (TDE) plus supply water (PSW), to supply the crop evapotranspiration (ETc) (100% PSW – control, 50% PSW + 50% TDE and 100% TDE), with and without phosphate fertilization in pre-planting. The contribution of nutrients to the soil and plant growth were analyzed. The results indicated that the wastewater presents potential fertilizer, reaching to the soil amounts of some nutrients exceeding the cotton’s needs, when 100% of the ETc was supplied via fertigation with domestic effluent, resulting in an increase in the growth rates of the plants. There was no interaction between the percentages of wastewater and phosphate fertilization in pre-planting. Phosphorus alone promoted significant variation only in the first cycle, indicating that there is a residual fertigation effect with domestic effluent on the nutrient supply.
