TL;DR: In this paper, the literature pertaining to the different aspects of fertigation and irrigation scheduling are reviewed and it is observed that irrigation and fertigation scheduled at 75% ET and 75% RDF, respectively could be a good alternate for saving water and nutrients with enhanced nutrient uptake, growth, yield and quality of crops.
Abstract: The primary objective of this review study was to determine the best irrigation and fertilizer scheduling practice in order to achieve maximum yield with maximum water and fertilizer use efficiency and highest nutrient uptake. It is found nutrient use efficiency could be as high as 90 per cent in fertigation as compared to 40 to 60 per cent in conventional methods. The amount of fertilizer lost through leaching can be as low as 10 per cent in fertigation whereas it is 50 per cent in the traditional system. It is observed that irrigation and fertigation scheduled at 75% ET and at 75% RDF, respectively could be a good alternate for saving water and nutrients with enhanced nutrient uptake, growth, yield and quality of crops. In this paper, the literature pertaining to the different aspects of fertigation and irrigation scheduling are reviewed.

TL;DR: A field study was conducted to evaluate the effect of irrigation and fertigation scheduling through drip irrigation in tomato (Solanum lycopersicum L.) during Rabi season of 2015-16 at Rajasthan College of Agriculture, MPUAT, Udaipur as discussed by the authors.
Abstract: Drip irrigation technique has proved its superiority over other methods of irrigation due to direct application of water and nutrient in the vicinity of root zone. A field study was conducted to evaluate the effect of irrigation and fertigation scheduling through drip irrigation in tomato (Solanum lycopersicum L.) during Rabi season of 2015-16 at Rajasthan College of Agriculture, MPUAT, Udaipur. There were three irrigation levels and five fertilization levels in split-plot design with three replications. Nutrient content in plant and fruit was found higher under the application of drip irrigation at 100 % PE (I1) and at 100 % RDF through fertigation (F1). Maximum nutrient uptake by tomato i.e. nitrogen (166.83 kg ha-1), phosphorus (41.59 kg ha-1) and potassium (183.08 kg ha-1) was recorded with treatment combination of drip irrigation at 75 % PE (I2) + 75 % RDF through fertigation + 2 foliar spray of 1 % urea phosphate (F3). Similarly, significantly maximum yield and growth attributes i.e. fruit yield (201.25 q ha-1), plant height (67.43 cm) and number of branches (12.33) were registered with treatment combination of drip irrigation at 75 % PE and 75 % RDF through fertigation + 2 foliar spray of 1 % urea phosphate. Drip fertigation method has proved to be very significant in improving nutrient uptake which finally resulting in enhancement of growth and yield of tomato crop.

TL;DR: In this article, a semi-solid byproduct which is obtained from wastewater treatment plants and treated as waste in developing countries like India where it remains deposited near municipal solid waste treatment plants.
Abstract: biomass carbon, enzyme activity INTRODUCTION The rapidly increasing human population and urbanization have led to the production of domestic and industrial waste in large amounts (Sharma and Dhaliwal, 2019). Sewage sludge is a semi-solid byproduct which is obtained from wastewater treatment plants and treated as waste in developing countries like India where it remains deposited near municipal solid waste treatment plants. It poses a great environmental threat when no management strategy is adopted for proper sludge disposal. Despite the widespread assumption that sewage sludge (SS) is a problem, its management as a valuable organic resource has become essential for sustainability. Moreover, SS is a potential source of nutrients that may be applied to agricultural lands (Bourioug et al., 2017). It may be used as an organic fertilizer that produces a favourable crop yield and it may even replace mineral fertilizers but only when it does not pose any risk to soil quality and human health (Ahmed et al., 2010). Its excessive use can also cause heavy metal toxicity in soils and plants (McGrath et al., 2000). Sewage sludge is relatively inexpensive in comparison to mineral fertilizers and has a higher amount of organic matter and plant nutrients, particularly nitrogen, phosphorus, potassium, calcium, and micronutrients (Jezierska-Tys and Frąc, 2009). It improves the physical, chemical, and biological properties of the soil (Aranyos et al., 2016; Meena et al., 2016). © 2020 Institute of Agrophysics, Polish Academy of Sciences

TL;DR: In this article , the impact of domestic sewage sludge (SS) on yield parameters and soil nutrient status under the pearl millet-wheat system using saline irrigation was evaluated.
Abstract: The present two-year experiment (2017-19) evaluated the impact of domestic sewage sludge (SS) on yield parameters and soil nutrient status under the pearl millet-wheat system using saline irrigation. The field study consisted of three irrigation treatments [canal water (0.35 dS/m); saline water (8 and 10 dS/m)], and five fertilizer treatments [control, SS (5 t/ha), SS (5 t/ha)+50% recommended dose of fertilizers (RDF), SS (5 t/ha)+75% RDF and 100% RDF]. The results revealed a significant reduction in the biological yield and yield attributes, and protein content of both crops with increasing salinity levels of irrigation water during both the years. However, all these parameters recorded significantly highest values under 100% RDF which was statistically at par with SS (5 t/ha) + 75% RDF treatment. The soil available sulphur (S) was significantly increased with 8 and 10 dS/m EC of saline water over canal water (0.35 dS/m) irrigation. But, SS (5 t/ha) + 75% RDF obtained 36.7 and 22.3% higher available S over control and 100% RDF, respectively. No significant effects were made in DTPA-extractable micronutrients (Fe, Mn, and Cu) with saline irrigation except Zn, which was reduced under saline environment. SS added treatments obtained higher micronutrient concentration over control. Hence, SS incorporation has proven useful in sustainable crop production and improved micronutrient availability in the soil.

TL;DR: The potential for generations of multiple electron-hole pairs by a single photon number, i.e., generation of multiple charge carriers, demonstrates the ability to get beyond the theoretical limitations of a single conversion capability as mentioned in this paper .
Abstract: Due to its ideal optoelectronic qualities for photovoltaic response, quantum dot solar cells are termed as solar cells of the third generation. Opportunities for dimensions and adaptability formation make QDs suitable suction devices to match the broad spectrum of the sun effectively. The potential for generations of multiple electron-hole pairs by a single photon number, i.e., generation of multiple charge carriers, demonstrates the ability to get beyond the theoretical limitations of a single conversion capability. Quantum solar dots show a dynamic efciency of up till Twelve percent energy, remarkably similar to their solar dye-sensitive counterparts. Although, the efciency of the Quantum Dot Solar Cells lags behind the standard solar single-junction photovoltaic. We'll talk about the rst emergence of quantum solar dots in minimalist terms in this review. The study will also look at how critical building blocks are being developed and features like the several interoperability areas in the Quantum Dot Solar Cell, movement of charge transporter, and re-integration into all different visual connections, which affect the efciency of power conversion. Additionally, carrier multiplication's fundamental notions and numerous exciton production are discussed in terms of their inuence on the efcient quantum dot solar cells conversion.

TL;DR: Oluwagbayide et al. as discussed by the authors presented the effects of water stress on crop yield and water productivity of two local varieties of pepper (Capsicum spp.) under various drip irrigation regimes in Southwest Nigeria.
Abstract: This research presents the effects of water stress on crop yield and water productivity of two local varieties of pepper (Capsicum spp.) under various drip irrigation regimes in Southwest Nigeria. Study Design: The study was conducted during the 2018 and 2019 cropping seasons at the Teaching and Research Farm of Agricultural and Bio-Environmental Engineering of Federal Polytechnic, Ilaro, Nigeria. The experiment was a 2 x 4 factorial experiments arranged in a randomized complete block design (RCBD) with two varieties of pepper (Capsicum chinense and Capsicum frutescens) and four drip irrigation regimes: 100%, 75%, 50% and 25% of actual crop evapotranspiration (ET100, 75, 50, 25) and Original Research Article Oluwagbayide et al.; JEAI, 42(8): 131-143, 2020; Article no.JEAI.61423 132 replicated four times. The experiment was repeated in the second year late season. Water was applied from 3 weeks after transplanting (WAT) after which growth parameters, crop water productivity and crop yield were monitored and subjected to statistical analyses. The water productivity, crop yield and other crop growth parameters such as plant height, number of leaves, fruit length and weight were higher during the two seasons for the two pepper varieties under ET100 and ET75 irrigation regimes compared with ET50 and ET25 respectively. A significant difference (p<0.05) was observed in the growth parameters in all the treatments. However, there was no significant difference (p>0.05) in the water productivity components for ET100 and ET75 irrigation regimes. The best water productivity was observed for the ET75 drip irrigation regime. Therefore, the ET75 regime was recommended for the two pepper varieties to ensure sustainable cultivation and production of the two varieties in the study area.

TL;DR: The five Rs of nutrient stewardship are a mnemonic device used to emphasize accuracy and precision for nutrient management to apply the (1) right source of fertilizer at the (2) right rate at (3) right time in the (4) right place with the (5) right irrigation method.

Place, dean for UF/IFAS Extension. The five Rs of nutrient stewardship is a mnemonic device used to emphasize accuracy and precision for nutrient management to apply the (1) right source of fertilizer at the (2) right rate at the (3) right time in the (4) right place with the (5) right irrigation method (Liu et al. 2019). Depending on state or region, the irrigation point may be omitted, leaving the four Rs of nutrient stewardship. Florida has many sandy soils that may result in mineral leaching, and this leaching may be impacted by irrigation scheduling (Waddell et al. 2000; Zhang et al. 2002). Therefore, this fifth R is imperative for sustainable nutrient management for commercial crop production. These main points of nutrient management (source, rate, time, place, irrigation) may help enhance sustainability by reducing pollution from nitrate leaching, nitrogen loss through ammonia volatilization, and climate change from soil greenhouse gas emission (Liu et al. 2015).

TL;DR: In this paper, the fertilizer prescription equations for tomato (Solanum lycopersicum L.) under drip fertigation on an alfisol were derived by following Ramamoorthy's Inductive cum targeted yield model.
Abstract: Soil test crop response (STCR) correlation studies under Integrated Plant Nutrition System were conducted in the western agro-climatic zone of Tamil Nadu during 2020-2021 to devise the fertilizer prescription equations for tomato (Solanum lycopersicum L.) under drip fertigation on an alfisol. The equations were derived by following Ramamoorthy’s Inductive cum targeted yield model. The nutrient requirement of N, P2O5 and K2O for producing one quintal of tomato fruit was found to be 0.22, 0.11, 0.27 kg respectively. The per cent contribution of nutrients were 37.93, 46.73 and 29.53 of N, P2O5 and K2O from soil (Cs) and 47.84, 31.12 and 74.13 of N, P2O5 and K2O from fertilizers (Cf) respectively. Two organic sources were applied viz., FYM (Farm Yard Manure) and Biocompost and the per cent contribution of nutrients from FYM were 38.36, 13.22 and 52.17 of N, P2O5 and K2O and from biocompost were 43.34, 10.90 and 57.00 of N, P2O5 and K2O respectively. Fertilizer adjustment equations were formulated for STCR-NPK alone, STCR-IPNS (FYM) and STCR-IPNS (Biocompost) by applying the basic parameters such as NR, Cs, Cf, Cfym, Cbiocompost. A ready reckoner of fertilizer doses for a set of soil test values at yield targets 80 and 90 t ha-1 was computed. The findings also showed that the adoption of STCR-IPNS could save more fertilizers.
