“…Maize being an exhaustive crop has high potential than other cereal crops and absorbs huge amount of nutrients during the growth stage from soil. Phosphorus is the second most crops limiting in most of soils [4]. It is essential for growth, consumption of starch and sugar, nucleus formation, photosynthesis, cell division and fat formation [4].…”

Intensive cropping pattern has deprived the soil of essential plant nutrients such as nitrogen (N), phosphorus (P) and potassium (K). This has resulted in lowering maize yield. P application control plant growth behavior. P is needed for utilization of sugar and starch, photosynthesis, cell division, nucleus and fat and albumen formation. K is well documented in protein synthesis, enzyme activation, stomatal movement, water relation and photosynthesis in plants. The aim of this study was to evaluate the impact of P and K on yield and yield components of maize. The experiment was carried out in randomized complete block design during 2014-15 at Agronomy Research Farm of Agriculture University Peshawar-Pakistan. Maize hybrid "Pioneer-3025" was use as a test crop. Experiment was composed of four levels of P (0, 60, 90 and 120 kg ha -1 ) and four level of K (0, 60, 90 and 120 kg ha -1 ). Result showed that P applied at 120 kg ha -1 increased rows ear -1 by 40%, grains row -1 by 18%, grains ear -1 by 41%, thousand grains weight by 8%, biological yield by 41%, stover yield by 34%, grain yield by 55% and harvest index by 10% over control. Similarly, K applied at 90 kg ha -1 increased rows ear -1 by 40%, grains row -1 by 15%, grains ear -1 by 36%, thousand grains weight by 8%, biological yield by 36%, stover yield by 25%, grain yield by 56% and harvest index by 15% over control. It is concluded that P at the rate of 120 kg ha -1 and K at the rate of 90 kg ha -1 should be applied for improved yield and yield component of maize in agro climatic conditions of Peshawar.

“…Peningkatan ini sejalan dengan penelitian Khan et al (2014) yang menyebutkan bahwa hasil jagung maksimum dimungkinkan dapat dicapai karena ketersediaan hara yang tepat selama durasi pengisian biji. Ketika unsur hara P ditemukan dalam dosis tinggi, maka dialokasikan pada bagian reproduktif yakni biji.…”

ABSTRAKUltisols merupakan tanah yang memiliki kandungan unsur hara rendah dan unsur hara P yang terikat pada Al dan Fe. Mikroorganisme pelarut fosfat (MPF) adalah kelompok mikroorganisme yang mampu untuk melepaskan P terikat sehingga dapat diserap tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi dosis pupuk hayati MPF dan pupuk P terhadap P-potensial, populasi BPF tanah dan hasil jagung (Zea mays. L) pada Ultisols Jatinangor. Percobaan dirancng dalam Rancangan Acak Kelompok yang terdiri atas sembilan perlakuan dan tiga ulangan. Perlakuan percobaan adalah pupuk SP-36 100 kg ha ). Hasil penelitian menunjukkan bahwa kombinasi dosis pupuk hayati MPF dan pupuk P berpengaruh nyata terhadap populasi BPF tanah dan hasil jagung, namun tidak berpengaruh terhadap P-potensial. Pemberian pupuk SP-36 dengan dosis 50 kg ha -1 dan 50 kg ha -1 pupuk hayati MPF merupakan kombinasi dosis terbaik.Kata kunci: pupuk hayati MPF, pupuk SP-36, P-potensial, populasi BPF, Jagung Total Phosphate Solubilizing Bacteria (Psb), Soil Potential P And Yield Of Maize (Zea mays. L) Affected By The MPF Application Grown On Jatinangor Ultisols ABSTRACTUltisol is low fertility soil and as low available P due to P fixation by Al and Fe. The phosphate solubilizing microbes (PSM) is the microbial group that enable realease fixed-P to soil solution and be absorbed by plant. This research was aimed to determine the effects of PSM biofertilizer and phosphate fertilizer dosage combination on soil potential P, total phosphate solubilizing bacteria (PSB) population and yield of maize (Zea mays L.) grown in Ultisols. This research used a Randomized Block Design that consist of nine treatments with three replications. The treatments were 100 kg ha -1 of SP-36 fertilizer, 50 kg ha -1 of PSM biofertilizer, SP-36 fertilizer (50 kg ha -1 and 100 kg ha ) repectively. The result showed that the combination of PSM and phosphate fertilizer dosage had significantly effect on PSB total population and maize yield, but did not not on potential P. This experiment suggested that SP-36 fertilizer with 50 kg ha -1 dosage and PSM biofertilizer with 50 kg ha -1 dosage is the best combination.
