本调查于2010-11年和2011-12年在Pantnagar的Govind Ballabh Pant农业技术大学的花卉种植示范中心进行。试验采用简单随机区组设计（RBD），设3个重复，25个处理，分别为生物肥料（固氮菌、光合细菌和KSB）、无机肥料及其组合。施用3/4 N、P、K+固氮菌+PSB + KSB（T24）对提高株高效果最好（112.84 cm），现蕾（7.31天），穗发芽所需天数（87.28天）、小花大小（10.22 cm）、穗长（109.27 cm）、穗轴长（52.6 cm）、叶绿素含量（70.98 SPAD）、光合速率（17.73 μ mol/m225）。而以3/4thN、P、K+固氮菌+光合细菌（T15）处理的叶片数和第一小花开放所需天数最多。3/4 N、P、K+固氮菌+ KSB（T18）处理花期最长。3/4 N、P、K+ PSB + KSB（T21）处理穗部气孔导度最大。
The present investigation was carried out at Model Floriculture Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, during 2010-11 and 2011-12. The experiment was conducted in simple Randomized Block Design (RBD) with three replications and twenty five treatments consisting of biofertilizers (Azotobacter, PSB and KSB), different levels of inorganic fertilizers, and their combinations. Application of 3/4th N, P and K+ Azotobacter +PSB + KSB (T24) was found most effective in enhancing plant height (112.84 cm), bud emergence (7.31 days), days taken to spike emergence (87.28 days), size of florets (10.22 cm), length of spikes (109.27 cm), rachis length (52.6 cm), chlorophyll content (70.98 SPAD), photosynthetic rate (17.73 μmol/m225). However, maximum number of leaves and days taken for opening of first floret were obtained when plants were fertilized with 3/4thN, P and K+ Azotobacter + PSB (T15). Maximum duration of flowering was obtained with application of 3/4th N, P and K+ Azotobacter + KSB (T18). Treatment 3/4th N, P and K+ PSB + KSB (T21) resulted in maximum stomatal conductance of spikes.
