“…Similarly, PE K ranged from 39.0 to 63.3 kg kg -1 observed in wheat is comparable to PE K range of 45.0 to 48.9 kg kg -1 recorded by [ 66 ] and PE K range of 49 to 96 kg kg -1 obtained by [ 61 ] and lower than the maximum PE K of 83.1 kg kg -1 recorded by [ 69 ]. Similar to our findings, the highest PE was recorded with the application of lower level of K [ 74 , 75 ].…”

Nutrient use efficiency is crucial for increasing crop yield and quality while reducing fertilizer inputs and minimizing environmental damage. The experiments were carried out in silty clay loam soil of Lalitpur, Nepal, to examine how different amounts of nitrogen (N), phosphorus (P), and potassium (K) influenced crop performance and nutrient efficiency indices in wheat during 2019/20 and 2020/21. The field experiment comprised three factorial randomized complete block designs that were replicated three times. N levels (100, 125, 150 N kg ha-1), P levels (25, 50, 75 P2O5 kg ha-1), and K levels (25, 50, 75 K2O kg ha-1) were three factors evaluated, with a total of 27 treatment combinations. Grain yields were significantly increased by N and K levels and were optimum @ 125 kg N ha-1 and @ 50 kg K2O ha-1 with grain yields of 6.33 t ha-1 and 6.30 t ha-1, respectively. Nutrient levels influenced statistically partial factor productivity, internal efficiency, partial nutrient budget, recovery efficiency, agronomic efficiency, and physiological efficiency of NPK for wheat. Nutrient efficiency was found to be higher at lower doses of their respective nutrients. Higher P and K fertilizer rates enhanced wheat N efficiencies, and the case was relevant for P and K efficiencies as well. Wheat was more responsive to N and K fertilizer, and a lower rate of P application reduced N and K fertilizer efficiency. This study recommends to use N @ 125 kg ha-1, P2O5 @ 25 kg ha-1 and K2O @ 50 kg ha-1 as an optimum rate for efficient nutrient management in wheat in mid-hills of Nepal.

Background: The negative effects of continuous use of chemical fertilizers on soil microbiology and agricultural sustainability are well established. The chemical fertilizers load in environment can be minimized by combined application of fertilizers and biofertilizers in crops like pulses which require less fertilizer-N and respond well to the use of biofertilizers. The objectives of the study were to see the effect of different biofertilizers in reduction of total fertilizer use and the response of field pea to combined application of chemical- and bio-fertilizers in terms of growth, yield and NUE.Methods: A field experiment was conducted during 2 consecutive rabi season of 2017-18 and 2018-19 at KVK, Chhatarpur, Jabalpur (Madhya Pradesh), India to evaluate the application of fertilizers and biofertilizers on growth parameter, nodulation, nutrient content and uptake, nutrient use efficiency, yield and economics of field pea. The experiment was laid out in randomized block design with five treatments in four replications. Treatments comprised of Control, Recommended dose (RD) of NPK (20: 60: 20 kg N, P2O5 and K2O/ha, respectively) (RDNPK), RDNPK + seed inoculation with Rhizobium @ 20 g/kg seed (RDNPK +R), RDNPK+R+phosphate solubilizing bacteria @ 20 g each/kg seed (RDNPK + R+PSB) and 75% of RDNPK + R+ PSB + potash solubilizing bacteria @ 5 kg/ha (75% RDNPK+ R+PSB+KSB). All other practices followed as per recommendation for the region and different observations and indices were recorded by following standard procedures.Conclusion: The application of 75% RDNPK+R+PSB+KSB was found best treatment among all others which resulted in highest grain yield (1682 kg/ha), protein content (23.1%), protein yield (388.5 kg/ha), net return (Rs. 46 623/ha) and B:C ratio (2.94). The nutrient use efficiency such as Partial Factor Productivity (PFP), Agronomic efficiency (AE), Physiological Efficiency (PE) and Economic Efficiency (EE) were also higher under combined application of fertilizers and biofertilizers. Thus, 75% RDNPK along with combined application of biofertilizers (R+PSB+KSB) may be applied for higher yield and return from field pea.

“…A declining pattern in AE was observed with raising N from 30 to 120 kg ha –1 ( Arduini et al, 2006 ) and 120 to 360 kg ha –1 ( Belete et al, 2018 ). Zemichael et al (2017) also reported decreasing trend in NUE traits with increasing doses of nutrients, explaining better performance with idea of supplying N at maximum absorption period resulting in higher biomass production while, supplying N at higher doses at planting time results in reduced uptake of N and S loses of nutrient with reduced efficiency.…”

Fertilization plays an irreplaceable role in raising crop yields; however, there are issues with unnecessary and blind use of chemical fertilizers, which raise the risk of contamination in the atmosphere. It is hypothesized that fertilization of nitrogen (N) and sulfur (S) will together improve the essential oil (EO) yield and composition of Tagetes minuta L. Thus, 2 years field experiment were carried out to evaluate the outcomes of N (0, 60, 90, and 120 kg ha–1) and S levels (0, 20, 40, and 60 kg ha–1) on T. minuta during 2018 and 2019. The growth, biomass, EO content and composition were influenced (P = 0.05) by N and S fertilization. N at 120 kg ha–1 and S at 60 kg ha–1 registered higher biomass (183.89 and 178.90 q ha–1, respectively) and EO yield (102.09 and 88.60 kg ha–1, respectively), than control. Stomatal density reduced significantly with increase of N and S levels, however, density of oil glands substantially increased with S at 40 and 60 kg ha–1. The major component of EO (Z-β-ocimene) significantly increased with 120 kg N ha–1 (42.59%) and 60 kg S ha–1 (42.35%), respectively. Available nutrients in soil and plant tissues substantially increased with N and S fertilization upto 120 and 60 kg ha–1, respectively. The highest nutrient use efficiency traits were recorded at 60 kg N ha–1 and 20 kg S ha–1. It was concluded that 120 kg N ha–1 and 40 kg S ha–1 can be proposed for T. minuta as a result of agronomic responses, which serves as a sustainable means of cropping.
