“…At present, agriculture is under huge pressure because of the growing demand for enhanced production in tune with the ever-increasing human population. On the other side, degradation and pollution of natural resources, global warming as well and climate change-associated abiotic and biotic stresses are causing negative impacts on farm productivity (Sairam et al, 2023;. Under these contexts, present agriculture should be climateresilient where ecologically hardly crops are to be chosen.…”

Background: Under the present context of global warming and climate change, the choice of an ecologically hardy crop is having prime importance. Nutrient management is an important approach for improving crop growth and productivity. Among all the nutrients, nitrogen helps in the overall growth of the plant. Nitrogen helps to synthesize chlorophyll and thereby supports building the protein units that enhance plant growth. As nitrogen is highly mobile, it is lost through different ways such as volatilization, leaching, nitrification, etc. Split application of nitrogen through proper scheduling is an important approach to reduce nitrogen loss as well as to improve nitrogen use efficiency. Hence, the investigation was conducted to find out how the scheduling of nitrogen is affecting pearl millet growth and productivity. Methods: The present study was conducted in kharif season of 2022 on pearl millet at Post Graduate Experimental Farm, M. S. Swaminathan School of Agriculture. The experiment was carried out in randomized complete block design with 3 replications and 9 treatments, namely, T1: control, T2: 50% basal RDN, T3: 100% basal RDN, T4: 50% basal RDN + 50% at 30 DAS, T5: 50% basal RDN + 25% at 30 DAS and 45 DAS, T6: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 95%, T7: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 90%, T8: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 85%, T9: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 80%. Result: The results showed that the application of 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 95% gave the maximum growth, yield, and income was also significantly higher with this application. So, it could be recommended to the farmers for growing pearl millet during kharif season in southern Odisha to achieve higher growth and productivity.

“…Despite adverse environmental conditions, plants can experience stress and may adjust itself by slowing down their growth [1]. Given climate change and population growth, increasing agricultural productivity is critical, with a projected 70 per cent rise in output needed by mid-century to meet global demands amid significant climate variability impacting horticultural crop production [2].…”

In recent decades, the global demand for vegetables has surged alongside population growth. However, biotic and abiotic stresses increasingly hinder seed germination, growth and yields. Plant growth regulators (PGRs) acting as chemical messengers are crucial in regulating plant development and responses to environmental stresses. Key phytohormones like abscisic acid, ethylene, salicylic acid and jasmonic acid play pivotal role in stress responses of vegetable crops. These hormones enable plants to sense and adapt to adverse conditions such as drought, salinity and extremities of temperatures. Through enzyme activation and hormone synthesis, plants enhance their resilience to stressors. The growth regulators initiate/activate a cascade event either on their own or by evolving a cross - talk within them that final recruits various transcription factors those in turn activate or suppress a variety of genes. The vital role of PGRs in mitigating stress impacts on vegetable crops, highlighting their potential in agricultural sustainability in future.

“…The use of nitrogen fertilizers in a judicious way ensures maximum herbage harvest of superior quality [15]. Nonetheless, its overuse should be avoided [24]. Nitrogen conveys the dark green coloration in plants and stimulates stem and leaf growth as well as promoting the growth and elongation of roots.…”

Most arid and semiarid areas are bare and greatly infested with intrusive wild species. Buffel grass (Cenchrus ciliaris L.) and Sudan grass (Sorghum sudanense Piper.) are the supreme drought-tolerant grasses that are commonly grown in dry regions. Besides water, nitrogen (N) is a vital element limiting the growth, yield, and herbage quality of such grasses since it has key roles in physiological and biochemical functions in plants. Hence, this study aimed at assessing the performance of Buffel and Sudan grasses under nitrogen fertilization in Mandera County. This study comprised a field trial laid as a split plot in a randomized complete block design with grasses being assigned to the main plots, whereas N rates (0, 35, 70, 105, and 140 kg N ha−1) occupied the subplots. Data were collected on growth parameters (plant height, leaf length, number of leaves per plant, leaf width, stem girth, and tiller number), yield parameters (shoot weight, root weight, and aboveground biomass yield—DBY), and quality attributes (acid detergent fiber—ADF, crude protein—CP, and neutral detergent fiber—NDF). Across the seasons, plant height progressively increased with increasing N rates up to a maximum of 141 and 246 cm for Buffel grass and Sudan grass, respectively, which were associated with a 105 kg N ha−1 rate. Nonetheless, there was no noteworthy enhancement in plant height (142 and 246 cm) with an additional upsurge in N fertilizer rate to 140 kg N ha−1 relative to the one of 105 kg N ha−1. Regarding the leaf length, Sudan grass had longer and wider leaves at all treatment levels than the Buffel grass. Plant height, leaf length, width, and the number of leaves per plant increased with increasing N level up to the rate of 140 kg N ha−1, though this was not statistically different from the rate of 105 kg N ha−1 for both kinds of grass. The results revealed that Sudan grass contained higher crude protein than Buffel grass at all levels of treatments (10.33 and 8.80% at the rate of 105 kg N ha−1, respectively). More so, crude protein content was found to be higher in plots where N application was performed than in the control plots. There were great associations between the dependent variables (DBY, ADF, NDF, and CP) and independent variables (plant height, leaf length, No. of leaves, leaf width, stem girth, and No. of tillers), with the coefficient of regression ranging from 0.56 to 0.96 for Buffel grass and 0.59 to 0.96 for Sudan grass. Findings from this study indicate that for optimal growth, yield, and nutrient content benefits, Buffel and Sudan grasses ought to be grown using nitrogen fertilizer at a 105 kg N ha−1 rate.
