ABSTRACT

 The study was conducted to investigate the effect of biofertilizer on wheat variety Zardana production at four locations of -1 -1 Balochistan. Biofertilizer (Azospirillum A1-Q + N 45 kg ha , P O 30 kg ha ) was 2 5 used to substitute for half of the Nitrogen (N) and phosphorus (P) fertilizer -1, application rates as compared to a high fertilizer treatment (N 90 kgha P2 5 O -1 60 kgha ). The high mineral fertilizer and biofertilizer + half mineral fertilizer treatments were compared with a control treatment (no fertilizer). Significant grain yield were measured at all sites, although, at all sites both fertilizer treatments apparently out yielded the control and the biofertilizer + half mineral fertilizer treatment out yielded the high fertilizer treatment by 220- -1 1180 kgha . Fresh yields differed significantly at all sites. At Mastung field, -1 both fertilizer treatments out yielded the control by 3000 kgha and at Quetta (Aghbarg field-2) the biofertilizer + half mineral fertilizer treatment out -1 yielded the others by over 3000 kgha . The results proved that the application -1 -1 of biofertilizer in combination with N 45kgha and P O 30 kgha increased 2 5 fresh yield from11% to 59% and suggested increases in grain yield of 20-46% as compared with control treatment.
