“…Improper water and nutrients management are the two main factors that adversely affect the growth and crop productivity under moisture stress (drought) condition in the Khyber Pakhtunkhwa (province of Pakistan [2]. Balance fertilization is essential for improving crop growth [3], increasing yield and harvest index [4], grain quality [5,6], fertilizer use efficiency [7] and profitability [8][9][10][11].…”

“…The S content in AS could be responsible for the early maturity in the maize genotypes as compared with urea and CAN having no S in them. In our previous study Amanullah et al confirmed that that the free S in SSP enhanced PM in maize as compared to DAP (Di-ammonium phosphate) and NP (nitrophos) having no free S [19].…”

“…However, urea has been considered to be less effective than other N fertilizers, due to N loss by ammonia volatilization, especially when used on soils of high pH or low CEC [16]. Our previous research work [19] on maize response to different phosphorus (P) fertilizers sources indicated that plots applied DAP (di-ammonium phosphate) produced heaviest seeds than SSP (single super phosphate) and NP (nitrophos), while application of SSP resulted in early PM and lowest TSW than urea and NP. Among the maize genotypes, the maize hybrid (P-3025) had significantly (P ≤ 0.05) higher TSW (259.5 g in Y1 and 282.3 g in Y2) than the two local cultivars (Azam and Jalal) in both years (Table 3).…”

“…Já Narang, Singh e Singh (1989) relataram aumentos na massa de 100 grãos com adubação fosfatada. Amanullah et al (2009), avaliando diferentes fontes de P, relataram aumentos na massa de 100 grãos e na produção de grãos com fosfatos solúveis. Entretanto, todos estes experimentos foram instalados em condições limitantes de P, enfatizando o efeito do adubo fosfatado nos componentes de produção quando existe a deficiência deste elemento.…”

“…A cultura do milho tem apresentado resposta a fontes de P para produção de biomassa (ERNANI;STECKLING;BAYER, 2001;CORRÊA et al, 2005;BATISTA et al, 2009) e componentes de produção (NARANG;SINGH, SINGH, 1989;MALHI;KHATTAK, 2009;RIVÉRA-HERNANDEZ et al, 2010), havendo superioridade dos fosfatos solúveis em relação aos naturais.…”
