Abstract
This study was conducted in seasons of 2014/2015 and 2015/2016 at Shandaweel Agriculture Research Station, Sohag, Egypt. The experimental design was randomized complete block design (RCBD) with three replications. The treatments were (1) Non-fertilization, (2). Control treatment (120, 45, 25 kg/fed NPK), (3). Humic acid+ 100% NPK, (4). Potassin +100% NPK, (5) Calfruit + 100% NPK, (6) Humic acid+ Potassin +100% NPK, (7) Humic acid+ Calfruit + 100% NPK, (8) Potassin + Calfruit + 100% NPK, (9) Humic acid+ Potassin + Calfruit, (10). Humic acid+ Potassin + Calfruit + 25% NPK, (11) Humic acid+ Potassin + Calfruit + 50% NPK (12) Humic acid+ Potassin + Calfruit + 75% NPK. Application of Pot.+Cal.+HA+75%NPK, produced the highest values of plant height at 90 and 120 DAT in both seasons and plant dry weight, bulb dry weight at 120 DAT in both seasons. While, Non-fertilization treatment gave the lowest values of plant height, bulb diameter, fresh plant weight, leaves fresh weight, bulb fresh weight, plant dry weight, leaves dry weigh, bulb dry weigh at 90 and 120 DAT and number of days to maturity in the two seasons. Generally, treatment of Pot.+Cal.+HA+75% NPK attained the highest values of total bulbs yield, bulb diameter, TSS%, D.M% in both seasons.
