Naseer) at the research farm of Arid Zone Research Institute, Dera Ismail Khan during two successive winter seasons, 2007-08 and 2008-09. The treatments consisted of HA alone (3 kg ha-1 or 1.5 kg ha-1) and in combination with full (60:40 kg ha-1) and half (30:20 kg ha-1) the recommended rates of NP f...

Three different rates of humic acid as 0, 5 and 10 kg ha-1 with three different P sources as nitrophosphate (NP), single superphosphate (SSP), and di-ammonium phosphate (DAP) at a recommended rate of 90 kg P2O5 ha-1 were applied. Soils amended with different P fertilizers with and without HA showed mix trend in AB-DTPA extracta...

However, the least days (85.22) to flowering were observed in planting medium amended with potting soil and largest bulblets (2.14cm) were found in compost amended sandy soil. As far as the effect of bulb size is concerned, maximum days to flowering (97.44), plant height (43.29cm), number of leaves (24.54), number of florets (19.17), bulblets plant-1 (24.30) and bulblet diameter (2.08 cm) were produced by growing large size...
