Abstract:

Water is precious and water scarcity is the major cause of drought. Indian agriculture primarily depends on irrigation facilities and drought is threatening when the country’s population is increasing rapidly. Due to climate change, drought adversely affect on agricultural production by lowering the produce. An experiment was conducted to assess the impact of PPFM (Pink Pigmented Facultative Methylotroph) and PGRs on alleviating the drought stress effects on tomato through root characters, yield and quality. Pot culture experiment was carried out in tomato variety PKM 1 with foliar spray of PPFM (1%), PPFM (2%), PPFM (3%) and growth regulators like brassinolide (1 ppm), salicylic acid (100 ppm), benzyl amino purine (100 ppm) and gibberellic acid (10 ppm) under drought condition created based on field capacity of soil. 50 per cent field capacity was maintained throughout the growth period for induction of drought and 100 per cent field capacity maintained as absolute control. The study indicated that the PPFM and PGRs could be effectively improving drought tolerance capacity of tomato crop under drought. Among the PGRs and different concentrations of PPFM used, PPFM (2%) was found to superior in improving root characters and yield. The highest root length of 25.9 cm was registered by PPFM (2%) which has the ability to protect the plant under drought. Foliar spray of 2% PPFM recorded highest specific leaf weight (5.96) followed by 100 ppm salicylic acid (5.66). The higher fruit yield of 552.9 g was maintained by PPFM (2%) followed by brassinolide (509.4) under drought. PPFM (2%) registered it s supremacy on higher lycopene content (5.92) followed by brassinolide (5.88).
