The study evaluated the impact of treated wastewater on plant growth through the use of hyperspectral and fluorescence-based techniques coupled with classical biomass analyses, and assessed the potential of reusing treated wastewater for irrigation without fertilizer application. Cherry tomato (Solanum lycopersicum) and cabbage (Brassica oleracea L.) were irrigated with tap water (Tap), secondary effluent (SE), and membrane effluent (ME). Maximum quantum yield of photosystem II (Fv/Fm) of tomato and cabbage was between 0.78 to 0.80 and 0.81 to 0.82, respectively, for all treatments. The performance index (PI) of Tap/SE/ME was 2.73, 2.85, and 2.48 for tomatoes and 4.25, 3.79, and 3.70 for cabbage, respectively. Both Fv/Fm and PI indicated that the treated wastewater did not have a significant adverse effect on the photosynthetic efficiency and plant vitality of the crops. Hyperspectral analysis showed higher chlorophyll and nitrogen content in leaves of recycled water-irrigated crops than tap water-irrigated crops. SE had 10.5% dry matter composition (tomato) and Tap had 10.7% (cabbage). Total leaf count of Tap/SE/ME was 86, 111, and 102 for tomato and 37, 40, and 42 for cabbage, respectively. In this study, the use of treated wastewater did not induce any photosynthetic-related or abiotic stress on the crops; instead, it promoted crop growth.

“…The results of the present study are in accordance to the finding of Ramesh et al [41] who reported that the increase in the number of effective tillers and panicle per m -2 was mainly by the application of plant growth hormones. Jagathjothi et al [9] also observed that the number of productive tillers m -2 enhanced by the foliar spray of nutrients.…”

“…Micronutrients such as Zn, B, Fe etc.., which are required in trace amounts, influences the metabolism of plants by involving in enzyme activation. Foliar application of nutrients in rice enhanced plant height, number of tillers and significantly increased photosynthetic rate and dry matter production through translocation of carbohydrates to the sink [9,10].…”

Rice (Oryza sativa L.) is one of the major cereals and the staple food crops which is cultivated all over the world. In order to meet the growing demand of population, it is important to increase the productivity of crop. The productivity of crop is influenced by nutrients and growth hormones. With this background, a field experiment was conducted during the month of January-May 2023 at wetland farms, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to evaluate the effect of different foliar nutrients and growth regulators on growth, physiology, biochemical and yield attributes in rice. The experimental layout was Factorial Randomized Block Design (FRBD) with two varieties (CO55 and ADT 57). The treatments consisted of foliar spray of T1- Control (water spray), T2- Nutrio-hormonal consortia 1, T3- Nutrio-hormonal consortia 2, T4- Rice booster 1 and T5- Rice booster 2 given at the booting stage and 15 days after the first spray. Among the treatments, T5- Rice booster 2 significantly improved leaf area (1813.99 cm2, 2059.78 cm2), leaf area index (4.53, 5.15), crop growth rate (32.07 g/m2/day, 37.89 g/m2/day), chlorophyll index (37.60, 41.73), photosynthetic rate (27.15 µmol CO2 m-2 s-1, 30.04 µmol CO2 m-2 s-1), Transpiration rate (11.83 mmol H2O m-1 s-1, 14.20 mmol H2O m-1 s-1 ), soluble protein content (16.23 mg/g, 17.30 mg/g), nitrate reductase activity (98.15 µg of NO2/g/h, 112.47 µg of NO2/g/h) in ADT- 57 variety at both sprays, respectively. Foliar application of rice booster 2 (T5) resulted in higher number of productive tillers (23), number of spikelets per panicle (165.5), spikelet fertility (95.48%), 1000 grain weight (17.35g), grain yield/ plant (31.40g), grain yield/hectare (6694.32 Kg/ha), harvest index (45.44%) in ADT 57 and resulted in 15% yield increment over the control. Thus the present study concluded that the foliar application of rice booster 2 (T5) significantly improved the growth, physiology, biochemical and yield attributes in rice variety ADT 57.
