In tropical regions with dry winters, low plant biomass accumulation during the period between spring–summer crop cultivations can negatively impact soil resources and make no‐till (NT) system unsustainable. Incorporating palisadegrass [ Urochloa brizantha (Hochst. Ex A. Rich.) R.D. Webster] [syn. Brachiaria Rich) Stapf] in traditional grain production areas could improve quality for subsequent crops lead to positive effects on yield. The objective of this study was evaluate growing...

Intercropping corn ( Zea mays L.) with palisadegrass [ Brachiaria brizantha (Hochst. ex A. Rich) Stapf] can result in high amounts of residue and improve nutrient cycling. Long‐season hybrids will live longer, competing palisadegrass, which may reduce both forage biomass yields. This study, conducted the state São Paulo, Brazil, had objective evaluating concentration yield different maturity ratings as affected by intercropped well dry matter production. The experimental design was...

Intercropping of maize (Zea mays L.) with perennial forage, such as palisade grass [Brachiaria brizantha (Hochst. ex A. Rich) Stapf], provides large amounts biomass that can be used straw for no-tillage systems or pasture animal grazing. In addition, the use narrow row spacing may increase grain yield. However, it is important to evaluate intercrops at different avoid reductions in both and forage production. The objectives this field experiment during two growing seasons Brazil were...

<p>Precision agriculture (PA) is growing considerably in Brazil. However, there a lack of information regarding to PA adoption and use the country. This study sought to: (i) investigate perception growers service dealership about technologies; (ii) identify constraints adoption; (iii) obtain that might be useful motivate producers agronomists technologies crop production systems. A web-based survey approach method was used collect data from farmers services involved with several...

Intercropping sorghum [ Sorghum bicolor (L.) Moench] with tropical perennial grasses and using the appropriate rate of sidedress N application can maximize grain yield (GY) revenue improve land‐use efficiency (LUE). The effects monocropped (MS) or intercropped palisadegrass ( Urochloa brizantha cv. Marandu; SPG) guineagrass Panicum maximum Mombaça; SGG) rates 0, 50, 100, 200 kg ha −1 on leaf nutrient concentration, GY, revenue, LUE were investigated during three growing seasons at Botucatu,...

Water scarcity threatens global food security and agricultural systems are challenged to achieve high yields while optimizing water usage.Water deficit can be accentuated by soil physical degradation, which also triggers losses through runoff consequently erosion.Although health in cropping within the Brazilian Cerrado biome have been surveyed throughout years, information about erosion impacts its mitigation still not well understood; especially concerning role of system diversification...

Intercropping grain with forage crops bridges the gap between agriculture and sustainability. In tropical regions, grasses are increasingly being adopted as winter pasture intercropped in rotation maize to maximize food production. However, current recommendations for nitrogen (N) fertilizer application based on monocropped ( Zea mays ), best N management approach intercropping systems remains unclear. A field experiment was carried out three growing seasons [monoculture maize, palisadegrass...
