Abstract :

A field experiment was conducted to evaluate the influence of PPFMs on growth and yield of foxtail millet under water deficit conditions during Rabi season. PPFM was applied to the crop by soil application at the time of sowing and foliar application at 30 & 45 days after sowing. Application of PPFMs enhanced chlorophyll and proline content and also enhanced the plant growth. Plant height and leaves per plant was increased due to application of PPFM. Numbers of leaves per plant were more in the treatment where PPFM was applied both to soil as well as to the foliage at 30 and 45 DAS. Chlorophyll (3.04) and Proline (285 µ moles/g of fresh weight) content increased due to application of PPFM both to soil and foliage at 30 DAS and 45 DAS. Panicle emergence was advanced by 8-10 days due to application of PPFM. The grain yield was increased due to application of PPFM, however foliar spray was more effective than soil application. Highest grain yield was recorded in the treatment where PPFM was applied both to soil as well as to the foliage. This study clearly showed increased growth, yield and drought resistant attributing factors.
