Aims: A study was carried out in the field aims to study the response of a calcareous soil cultivated by soybean to the application of K-silicate (K-Si), K-humate (K-H), and compost at application rates 50% and 100% of the recommended dose. Study Design: Complete randomized block design with three replicates. Place and Duration of Study: At El-Nubaryia Agricultural Research Station (latitude of 30° 30°N longitude of 30° 20°E) Agricultural Research Center (ARC), Nubaryia, Egypt (Summer seasons of 2018 and 2019). Methodology: Compost was mixed with surface soil a week before cultivation at application rates 3.75 and 7.5 kg plot-1 (3.91 and 7.81 t ha-1, respectively). Powder K-H was spread on soil at application rates 7.5 and 15 g plot-1 while aqueous solutions of K-Si; 8 and 16 mL L-1 for plot was sprayed on soil 30, 60, and 90 days after cultivation. Results: Results showed that soil moisture(SM, %) was increased by the 100% application rate in the order compost (20.6%) > K-Si (19.3%) > K-H (19.1%). A significant increase was found in the seed yield (kg ha-1) by 129.5%, 84.8% and 70.6% by compost, K-H and K-Si, respectively. Compost at 100% application rate showed the most significant increase in the available nitrogen N (mg kg-1) in soil by 104.4% followed by K-H (by 81.8%) then K-Si by 23.4%. Compost also showed the most significant increase in the N uptake from soil (kg ha-1 soil) by seeds and straw followed by K-H then K-Si. The nutrient use efficiency (NUE, %) and agronomic efficiency (AE) values decreased in the order K-H > K-Si > compost at 50% and 100% application rates. Conclusion: The quite smaller dose and ease of field application by spraying may make the K-H more agronomically efficient than K-Si and compost.

A field experiment was conducted at Regional Research Station, Karnal, CCS Haryana Agricultural University during spring 2017 to study on different planting method and nitrogen level on growth parameter and nitrogen use efficiency of sugarcane. The experiment was conducted in split plot design with three replications. The treatments comprises of four methods of planting viz. conventional planting at 75 cm (M1), half ridge open furrow irrigation planting at 75 cm (M2), wide bed and furrow paired row planting (M3) and wider planting (M4) at 120 cm and six different nitrogen levels viz. control (N1), 75 (N2), 100 (N3), 125 (N4), 150 (N5), 175 kg N ha-1 (N6). Germination count was significantly affected by planting methods at 30 and 45 DAP, however, it was found to be non significant among nitrogen levels. Neither the planting methods nor the nitrogen levels had any significant effect on nutrient use efficiency, brix, pol, juice purity and commercial cane sugar. Significantly higher sugar yield (11.9 t/ha) was recorded in wide bed and furrow paired row planting which was 22.7, 8.2, and 6.3 per cent higher than conventional, wider planting and half ridge open furrow method, respectively. Lower sugar yield (9.7 t/ha) was recorded in conventional method. Among nitrogen levels, sugar yield increases with successive increase in nitrogen application upto recommended dose of 150 kg N/ha.

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 field experiment was conducted at M/s.Rashtriya Chemicals and Fertilizers, Ltd., Mumbai, India, (RCF) experimental farm to evaluate the effect of ZnO Nanoparticles (ZnO NP) in combination with N: P: K (15: 15:15) complex fertilizer “Suphala” of RCF Ltd. on growth attributes of brinjal (Solanum melongena L) as well as nutrient use efficiency. The experiment was carried out in randomised block design with three replications. The first treatment (T-1), comprised of recommended dose of fertilizer (RDF), N: P: K (50:50:50), applied at the time of transplantation. The second treatment (T-2) was conducted with RDF in combination @ 2kg ZnSO4 (bulk)/ha. The third treatment (T-3) was added, N: P: K (12.5; 12.5; 12.5) in combination to ZnO NP @ 4500mg/ha. The forth treatment (T-C) was without any fertilizer. All treatments were given appropriate quantity of nitrogen per hectare as urea at the 30th day of transplantation. The combination N: P: K (12.5; 12.5; 12.5) and ZnO NP @ 4500mg/ha yielded 91% and 45.3% higher brinjal yield and biomass respectively than the treatment with only RDF. It was also observed that 38% and 21% higher yield and biomass respectively were recorded in the treatment where combination of RDF with ZnSO4 (bulk) over RDF was used alone. The results of field trials reveal that, there was synergistic effect of ZnO NP @ 4500mg per hectare with N: P: K complex fertilizer on growth attributes of brinjal as well as nutrient use efficiency.

A field experiment was conducted during Kharif 2017 at Devanahalli village, Bengaluru rural district of Karnataka to evaluate the effect of different approaches of nutrient application on yield,  nutrient uptake and use efficiency by carrot (Daucus carota L.). The experiment was laid out in randomized complete block design replicated thrice with eight treatments comprisingT1 (STCR target 20 tha-1  through inorganics), T2 (STCR target 20 tha-1  through integrated), T3 (STCR target 25 tha-1  through inorganics), T4 (STCR target 25 tha-1  through integrated), T5 (RDF (75: 63: 50) N, P2O5, K2O kg ha-1+ FYM), T6 (LMH /STL + FYM), T7 (Farmers practice (92.6:159:0) N, P2O5 kg ha-1 + FYM), T8 (Absolute control).Results revealed that significantly higher root (27.51 t ha-1)  and shoot (16.48 t ha-1) yield were recorded in STCR target of 25 t ha-1 through   integrated approach. Similarly, higher total uptake of nitrogen, phosphorus and potassium  (297.07 kg, 57.48 kg and 253.81 kg ha-1, respectively) by carrot and the higher apparent recovery   efficiency (0.35, 0.08 and 0.58 kg kg-1 of N, P2O5 and K2O, respectively) and agronomic nutrient use efficiency (26.10, 12.37 and 48.25 kg kg-1 of N, P2O5 and K2O, respectively) were recorded in the same STCR target of 25 t ha-1 through integrated approach. However, the better profit was recorded (value cost ratio: 43.30) in STCR target of 25 t ha-1 through inorganics. The STCR target of 25 t ha-1 through integrated approach had the most positive effect for the carrot cultivation.

Abstract We conducted on-farm trials in the southern Guinea Savanna of Ghana in 2016 and 2017 to evaluate soyabean response to three fertiliser blends to guide farmers towards profitable adoption of appropriate phosphorus (P) fertiliser blend for improved soyabean production. Old YARA Legume (OYL), New YARA Legume (NYL) and Triple Superphosphate (TSP) fertiliser blends were evaluated. In both years, the P fertiliser blends were evaluated in a Randomised Complete Block Design with 20, 30, and 40 kg P ha-1 application rates together with control. P fertiliser application increased soyabean yields by 1070 kg ha-1. In 2016, fertiliser blend use efficiency (BUE) ranged from 2.9 kg grain per kg fertiliser blend applied with the NYL applied at 40 kg P ha-1 to 7.4 kg grain per kg fertiliser blend applied with the TSP applied at 40 kg P ha-1 with significant differences between treatments. In 2017, BUE ranged from 2.5 kg grain per kg fertiliser blend applied with OYL applied at 40 kg P ha-1 to 9.2 kg grain per kg fertiliser blend applied with the TSP applied at 40 kg P ha-1 with significant differences between treatments. However, P use efficiency did not significantly differ between the different treatments both in the 2016 and 2017 trials. In both 2016 and 2017 trials, the highest benefit cost ratio was attained at the lowest application rate for all the three fertiliser blends suggesting the need to review the current application rate of 30 kg P fertiliser ha-1 promoted in northern Ghana. Furthermore, the provision of credit and/or subsidy for farmers by the government is required to enable uptake and utilisation of fertilisers by farmers.

Background: The present investigation was concentrated to determine the nutrient uptake capacity of different varieties of rice (Oryza sativa L.) under delayed planting condition. The purpose of the study is to evaluate the nutrient content in straw and grain in different varieties of rice to understand the nutrient acquisition capacity. Methods: The experiment was conducted during kharif-2018 in a split plot design with three replications at Agricultural Research Farm, BHU, Varanasi with a combination of four rice varieties (HUR-3022, DRR-44, HUR-4-3 and HUR-105) as subplot factor and three dates of planting (06/09/2018, 13/08/2018 and 20/08/2018) as main-plot factor. Result: Among the varieties, DRR-44 was observed efficient for N, P and K absorption under timely planting conditions and recorded higher N content (1.01%) than HUR-3022 (0.91%) and HUR-105 (0.86%). The P (0.45%) and K (0.29%) content were observed highest for the variety DRR-44 on the first date of planting (06/08/2018). Maximum N, P and K uptake by grain and straw were recorded in DRR-44 followed by HUR-3022 and HUR-105. DRR-44 was also the highest grain and straw yielder. Thus, improved varieties of rice with higher nutrient use efficiency should be the priority for quality and higher yield of straw and grain of the crop.

Global Concern

Imbalanced use of fertilizers for agricultural production has now become a global concern. As a result, studies on how to use efficient methods to reduce nutrient applications at the same time increasing or maintaining crop yield, reducing nutrient losses and improving nutrient use efficiency are imperative. Accordingly, a pot study was conducted to evaluate whether zeolite application might improve selected soil properties, nitrogen use efficiency during maize cultivation. Among all treatments, irrespective of the nitrogen level, NUE (N recovery and agronomic use efficiency of N) showed an increasing trend with the increase of zeolite levels, nitrogen levels and their combination. The highest N recovery and agronomic NUE was obtained in N200Z7.5 (Nitrogen @ 200 kg ha-1 + Zeolite @ 7.5 t ha-1), was on par with N200Z5 (Nitrogen @ 200 kg ha-1 + Zeolite @ 5 t ha-1). N uptake by maize at harvest was highest in N200Z7.5 (Nitrogen @ 200 kg ha-1 + Zeolite @ 7.5 t ha-1).

Timing nutrient application to periods of high nutrient demand could increase nutrient use efficiency and reduce the potential for fertilizer leaching or runoff. However, current recommendations for field nursery and landscape ornamentals (extension publications) suggest fertilizing in late fall and early spring despite research with perennial fruit crops that demonstrates low uptake potential during those times. Research is needed to resolve this apparent conflict. Application rates for woody ornamentals, established in the 1960s and 1970s, also need reexamination in the light of environmental concerns.

Nanoscience coupled with nanotechnology emerged as possible cost-cutting approach to prodigal farming and environmental clean-up operations. Hence there is a need for a more innovative fertilizer approach that can increase the productivity of agricultural systems and more environmental friendly than synthetic fertilizers. The trial was laid out in randomized complete block design with 11 treatments in three replications. The field experiment was carried out at Main Agricultural Research Station, University of Agricultural Sciences, Raichur during Kharif seasons of 2019 and 2020. In this research, we studied the recent development and potential benefits derived from the use of nanofertilizers (NFs) in modern agriculture. Nanofertilizers facilitate slow and steady release of nutrients, thereby reduce the loss of nutrients and enhance the nutrient use efficiency. In the present study, the nanofertilizers such as IFFCO nanonitrogen (nano N), IFFCO nanocopper (nano Cu), IFFCO nanozinc (nano Zn) and IFFCO sagarika were sprayed to the maize crop in different combinations with recommended dose of fertilizers. Among the different combinations of nanofertilizers with recommended dose of fertilizers the treatment T11 [50% N, 100% PK, 0% Zinc + 2 sprays of IFFCO nano N (4ml/l) mixed with IFFCO Sagarika (2 ml/l)] showed significant effect on the growth and yield parameters with maximum yield of 58.90 q/ha and highest B:C of 2.99. Whereas, treatment T10 [50% N, 100% PK, 0% Zinc + 2 sprays of IFFCO nano N (4ml/l) mixed with nano Zn (2 ml/l) and IFFCO nano Cu (2ml/l)] was found superior with regard to management of Turcicum leaf blight disease with minimum of 18.20 per cent severity.

The use of carbon nanoparticles (CNPs) as a fertilizer synergist to enhance crop growth has attracted increasing interest. However, current understanding about plant growth and soil response to CNPs is limited. In the present study, we investigated the effects of CNPs at different application rates on soil properties, the plant growth and nutrient use efficiency (NUE) of corn (Zea mays L.) in two agricultural soils (Spodosol and Alfisol). The results showed that CNPs affected corn growth in a dose-dependent manner, augmenting and retarding growth at low and at high concentrations, respectively. The amendment at the optimal rate of 200 mg CNPs kg−1 significantly enhanced corn growth as indicated by improved plant height, biomass yield, nutrient uptake and nutrient use efficiency, which could be explained by the higher availability of phosphorus and nitrogen in the amended soils. The application of CNPs largely stimulated soil urease activity irrespectively of soil types. However, the responses of dehydrogenase and phosphatase to CNPs were dose dependent; their activity significantly increased with the increasing application rates of CNPs up to 200 mg kg−1 but declined at higher rates (>400 mg kg−1). These findings have important implications in the field application of CNPs for enhancing nutrient use efficiency and crop production in tropical/subtropical regions.
