This study aimed to evaluate the residual effect of phosphorus sources and application techniques in the intercropping of forages during off-season crops. The experimental design was randomized blocks in a 4 × 2 + 1 factorial, being four sources of phosphorus [Bayóvar Reactive Phosphate (BRP), Monoammonium Phosphate (MAP), Simple Superphosphate (SS) and Triple Superphosphate (TS)], two application techniques (broadcasting and on rows) and an additional without phosphorus. The experiment was conducted during the off-season crop. The residual effect of phosphorus fertilization increased the growth and the production of biomass of forage sorghum regarding broadcast SS and TS sources. The lowest P contents in the tissue of plants fertilized with SS and TS may be attributed to the diluting effect, as it achieved the highest production of biomass. The application of TS favored a greater dry matter production in Brachiaria brizantha cv. Piatã. At the depth 0.00-0.05 m, there was a higher P content with the application of BRP. However, the production of biomass was low, a factor that may be related to an overestimation of P bound to Ca by the Mehlich-1 extractor. Under cultivation conditions, broadcast SS and TS had a higher residual effect.

“…In all treatments, except the control which had no P application, the highest levels of P were observed in the 0-10 cm layer compared with the 10-20 cm layer (Figure 2). Soil management with minimal mobilization and ways of applying phosphate fertilizers increase the accumulation of P on the soil surface over time, creating the problem of nutrient stratification (Barbosa, Arruda, Brod, & Pereira, 2015;Cade-Menun et al, 2015;Costa et al, 2009;Nunes et al, 2011;Scheiner & Lavado, 1998;Smith, Huang, & Haney, 2017;Sousa et al, 2016). Phosphorous accumulation in the 0-10 cm layer occurred because the sowing of grains (spring/summer crop) deposited the fertilizer up to a maximum depth of 0.10 m (Denardin et al, 2008), whereas for autumn/winter crops, the fertilizer effectively reaches depths of up to 0.05 m, in addition to the low mobility of P in the soil (Marschner, 2012;Rheinheimer & Anghinoni, 2001;Rheinheimer et al, 2008).…”

In soils with adequate levels of fertility, it is possible to manage phosphate fertilization aiming at the grain production system, instead of each isolated crop. The objective was to evaluate the effects of the management of phosphate fertilization, place and time, on the soil and leaf P content, and crop yield in grain production systems. An experiment was conducted at the farm level in the municipality of Nazareno, state of Minas Gerais, Brazil, for four years on soil with adequate level of fertility. The treatments consisted of the management of phosphate fertilization by broadcast or furrow and dose for each crop or for the production system (spring/summer and autumn/winter crops), being: Control = without phosphate fertilization; Conventional = phosphate fertilization in the furrow in each crop; BTP = phosphate fertilization of the grain production system to broadcast; TPS = phosphate fertilization of the grain production system in the furrow of the spring/summer crop; TPW = phosphate fertilization of the grain production system in the furrow of the autumn/winter crop. Soil P content was evaluated in the third year of implantation, and the crops yield every season crop (maize, soybean, common bean and wheat). The P content in the leaves of maize and soybeans were evaluated in the spring/summer crops. The application of the total dose of phosphate fertilization for both crops in the sowing furrow of the spring/summer or autumn/winter crops (TPS and TPW) promoted operational advantages and increased soil P content in the 0-0.20 m layer, without reducing the yield of the spring/summer crops. Leaf P content was not affected. The Conventional management (phosphate fertilization in the furrow in each crop) provide greater yield of common beans and wheat during autumn/winter crops, which are more subject to water restriction due to less rainfall, even without increasing the soil P content.

RESUMO - Entender como o manejo de aplicação de fertilizantes interfere no sistema produtivo é primordial para amanutenção do máximo aproveitamento da produtividade dos híbridos. Desta forma, o objetivo com este trabalho foiverificar a influência da forma de adubação de semeadura, feita a lanço ou localizada, na produtividade de grãos de 33híbridos comerciais de milho, em quatro diferentes safras agrícolas. Foram conduzidos quatro experimentos no municípiode Serra do Salitre, em Minas Gerais (MG), nos meses de novembro de 2015 e de 2016, janeiro e fevereiro de 2017 efevereiro de 2017. O delineamento experimental utilizado foi o de blocos completos casualizados com três repetições,com os tratamentos dispostos em esquema fatorial de 33 x 2, sendo 33 híbridos de milho e dois sistemas de adubação desemeadura: a lanço e localizada. Na análise conjunta da produtividade de grãos, ocorreram interações significativas entrehíbridos e safras, e também entre formas de adubação e safras. Apesar da interação significativa, o sistema de adubaçãolocalizada foi superior em ambas as safras avaliadas, considerando nível de significância de 5% pelo teste de Tukey.Mesmo com as condições climáticas menos favoráveis na segunda safra, a adubação localizada mostrou-se mais eficiente.Palavras-chave: adubação localizada, adubação a lanço, segunda safra, Zea mays L.EFFECT OF SOWING FERTILIZATIONON GRAIN PRODUCTIVITY OF MAIZE HYBRIDSABSTRACT - Understanding how the management of fertilizer application affects the production system is essentialto maximize the productivity of the hybrids. The objective of this study was to verify the effect of broadcasting andbanding fertilization on grain yield of 33 commercial maize hybrids in four different crop seasons. Four experimentswere carried out in Serra do Salitre, state of Minas Gerais, Brazil, in November 2015, November 2016, January andFebruary 2017. The experimental design was a randomized complete block with three replications, with treatmentsarranged in a 33 x 2 factorial scheme, 33 corn hybrids and two sowing fertilization forms, broadcast and bandapplication. The joint analysis of grain yield showed significant interactions between hybrids and crop seasons, andalso between fertilization systems and crop seasons. The unfolding of the interaction between the fertilization formsand crop seasons showed that the yield of grains in the band fertilization was superior compared to the broadcastfertilization, regardless the crop season evaluated. Even with the less favourable climatic conditions in the secondharvest, the band fertilization showed to be more efficient when compared to the broadcast fertilization.Keywords: broadcast fertilizer, band fertilizer, second crop, Zea mays L.
