Abstract

The present investigation was conducted in the Experimental Farm, Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab during year 2023-24 with eight treatments comprising of different doses of integrated nutrients viz: T1 i.e., Control, T2 i.e., VAM (0.05 g/m2) + NPK (20:10:10 g/m2)T3 i.e., PSB (0.05 g/m2) + NPK (20:10:10 g/m2), T4 i.e., Azospirillum (0.05 g/m2) + NPK (20:10:10 g/m2) ,T5 i.e., VAM + PSB (0.05+0.05 g/m2) + NPK (20:10:10 g/m2), T6 i.e., VAM + Azospirillum (0.05 + 0.05 g/m2) + NPK (20:10:10 g/m2), T7 i.e., Azospirillum + PSB (0.05 + 0.05 g/m2) + NPK (20:10:10 g/m2), T8 i.e., RDF (40:20:20 g/m2), with three replications in randomized block design. The maximum plant height (41.72cm), number of leaves per stem (12.81cm), number of stems per plant (12.29), stem length (15.19cm), diameter of main stem (8.12mm), plant spread (33.13cm2), Leaf length (37.20cm), were recorded in T7 i.e., Azospirillum + PSB (0.05 + 0.05 g/m2) while minimum plant height (28.94cm), number of leaves per stem (8.14), number of stems per plant (6.92), stem length (9.18cm), diameter of main stem (5.59mm), plant spread (17.67cm2), was recorded under T1 i.e., control. T7 i.e., Azospirillum + PSB (0.05 + 0.05 g/m2) shows best results in number of flowers per plant (18.85) While minimum flowering attributes i.e., number of flowers per plant (6.44) was resulted in T1 i.e., control.

综合养分管理对变种菊花（Dendranthema grandiflorum）生长和开花的影响研究Pusa Shwet

本研究于 2023-24 年期间在旁遮普省法特加尔萨希布市马塔古杰里学院农业系的实验农场进行，共进行了八次处理，包括不同剂量的综合养分，即T1 即对照，T2 即 VAM（0.05 克/平方米）+氮磷钾（20:10:10 克/平方米），T3 即 PSB（0.05 克/平方米）+氮磷钾（20:10:10 克/平方米），T4 即、Azospirillum (0.05 g/m2) + NPK (20:10:10 g/m2) , T5 即 VAM + PSB (0.05+0.05 g/m2) + NPK (20:10:10 g/m2), T6 即、T7 即 Azospirillum + PSB（0.05 + 0.05 g/m2）+ NPK（20:10:10 g/m2），T8 即 RDF（40:20:20 g/m2），采用随机区组设计，三次重复。植株高度（41.72 厘米）、每茎叶片数（12.81 厘米）、每株茎数（12.29）、茎长（15.19 厘米）、主茎直径（8.12 毫米）、植株平展度（33.13 平方厘米）、叶片长度（37.20 厘米）在 T7（Azospirillum + PSB）和 T8（RDF（40:20:20:20 克/平方米））中最高、而 T1（即对照）的植株高度（28.94 厘米）、每茎叶片数（8.14）、每株茎数（6.92）、茎长（9.18 厘米）、主茎直径（5.59 毫米）、植株展开度（17.67 平方厘米）均为最低。T7 即 Azospirillum + PSB（0.05 + 0.05 g/m2）在单株花数（18.85）方面显示出最佳效果，而 T1 即对照的开花属性即单株花数（6.44）最低。
