    Abstract: Aim: In arid and semi-arid areas recycling of water may have a greater impact on future usable water supply than any of the other technologies aimed for increasing water supply. Efforts have been taken on maximizing the benefit and minimizing the detrimental effects on people or the environment due to continuous usage of treated wastewater. Hence, the current experiment was aimed to study the effect of treated wastewater in combination with organic and inorganic nutrients on bajra napier hybrid grass on yield and quality parameters. Study Design: The field experiment was conducted using secondary treated wastewater, manure and inorganic nutrients in Bajra Napier hybrid grass variety CO(BN) 5 with a strip plot design and four replications. Place and duration of study: The experiment was conducted in Veterinary College and Research Institute, Orathanadu, Thanjavur, Tamil Nadu, during 2018-19 (10.62ᵒ N latitude and 79.26ᵒ East longitude). Methodology: The five ratios of irrigation water were used in horizontal factor treatments and four different nutrient combination treatments were allotted in the vertical factor. The plot was divided into 27 m2 with 2 m space between the plots. The two budded setts of bajra napier hybrid grass variety CO (BN)-5 were planted at 60 x 50 cm spacing. The flood irrigation and nutrients (basal and top-dressing) were applied as per the treatments. Results: The use of treated wastewater for irrigation combined with manure and inorganic nutrients significantly increased the total green and dry fodder yields. Irrigation treatment with treated wastewater alone + 100% inorganic nutrients (I5N1) recorded significantly higher total green and dry fodder yields of 431.0 and 76.7 t ha-1 yr-1, respectively, than all other treatment combinations. Irrigated with groundwater alone (control) without nutrients (I1N4) recorded the lowest total green and dry fodder yields (222.5 and 47.6 t ha−1 yr-1, respectively). The average crude protein content of all total cuttings was significantly higher (13.53%) in I5N1 than all other treatments. On the other hand, the average crude fibre content (28.03%) was significantly lower in the treatment I5N1 as compared to irrigated with groundwater without nutrients (31.18%). Conclusion: The perennial fodder crop Bajra Napier hybrid grass variety CO (BN) 5 cultivated under-treated wastewater combined with manure and inorganic nutrients increased the total green and dry fodder yields with beneficial proximates. The use of treated wastewater for fodder cultivation helps conserve groundwater and effectively utilize available nutrients in treated wastewater.

    Abstract: Aim: The current study focuses on the threats to the environment and human health that relate to using treated wastewater produced from the municipal sewage treatment plant of Orathanadu for irrigation purposes. Study Design: For this purpose, samples were taken monthly from the outflow wastewater and grouped into seasons. Place and Duration of study: Municipal sewage treatment plant located at Orathanadu, Tamil Nadu, during 2019. Methodology: The treated wastewater quality parameters such as pH, EC, total dissolved solids, total suspended solids, five days biological oxygen demand, chemical oxygen demand, and sodium adsorption ratio were measured monthly and grouped season-wise. Results: In treated wastewater, the minimal mean electrical conductivity values, total dissolved solids, five days biochemical oxygen demand, chemical oxygen demand, and sodium adsorption ratio were 0.81 dS m-1, 515.20 mg L-1, 25.50 mg L-1, 14.85 mg L-1, and 1.59, respectively. The suitability for irrigation based on the Sodium Adsorption Ratio (SAR) was calculated with standard equations and found experimentally as 1.59, 1.62, 1.59 and 1.56 during winter, summer, monsoon and post-monsoon seasons, respectively. To assess water suitability for irrigation, irrigation water classes are utilized for salinity hazard (EC) and sodium hazard (SAR), and samples were C3-S1 class in all four seasons. Furthermore, the data indicated a slight to moderate restriction on using this treated wastewater in irrigation due to chloride hazards. Conclusion: The results showed that treated wastewater meets national and international irrigation criteria and that treated wastewater can be used without restriction in light and medium-textured soils and in clay soils with leaching and drainage.

    Abstract: Controlled release nitrogen fertilizers could be an excellent management approach for improving nitrogen fertilizer efficiency. The present study aimed to investigate the effect of coated urea fertilizers to increase nitrogen uptake and utilization of maize. The nitrogen use efficiency of maize from various biodegradable polymer-coated urea fertilizers, such as palm stearin coated urea (PSCU), pine oleoresin coated urea (POCU), and humic acid coated urea (HACU), was determined in a pot culture experiment conducted at the Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore, during 2021. The coating materials have been coated on urea with different coating thicknesses, viz., PSCU - 5, 10, 15%, POCU – 2, 4, 6%, and HACU - 5, 10, 15%. Among all the treatments, T11: HACU 15% produced highest grain yield (72.0g plant-1) followed by T7: POCU 4% (69.7 g plant-1) and T4: PSCU 10% (69.0g plant-1). In terms of dry matter production, T10: PSCU 10% produced maximum dry matter (186.5g plant-1), followed by T11: HACU 15% (186.2 g plant-1), and T7: POCU 4% (185.3g plant-1). The nitrogen uptake by the maize plant was higher in T7: POCU 4 % (1.62g plant-1), followed by T11: HACU 15% (1.59 g plant-1) and T4: PSCU 10% (1.59g plant-1). Irrespective of treatments, the highest nitrogen utilization by the maize crop was found in T7: POCU 4% (73.9%) followed by T4: PSCU 10% (71.1%) and T11: HACU 15% (70.9%) treatments. When compared to uncoated urea fertilizer, all coated urea fertilizers outperformed uncoated urea fertilizer in terms of grain yield, dry matter accumulation, and nitrogen uptake. To improve the nitrogen use efficiency, coated urea fertilizers prove to be a promising alternative to uncoated urea fertilizers.
