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.

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.

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).

The experiment was carried out at the District Seed Farm, Adisaptagram, Hooghly (West Bengal), India during two consecutive winter seasons of 2011-12 and 2012-13 to find out optimum N dose of potato cultivars for getting higher yield as well as to identity efficient potato cultivars regarding N use. Average yield of potato cultivars increased significantly with increase in N supply up to 225 kg N ha-1, then tended to decrease slightly as nitrogen levels increased further. Tuber yield of cultivars Kufri Shailja and Kufri Jyoti was increased significantly with increase in nitrogen level up to 225 kg N ha-1 and further addition of N decreased yield. Yield of Kufri Himalini was increased with increase in N level up to 300 kg N ha-1 but the yield increment from 225 kg N ha-1 to 300 kg N ha-1 was not significant. Application of less N decreased average potato tuber yield by 5.3, 18.7 and 65.1% with 150, 75 and 0 kg N ha-1 respectively, compared to 225 kg N ha-1. Nitrogen use efficiency (NUE) decreased towards higher N levels for all cultivars. NUE of Kufri Himalini was higher at all N levels. The results revealed that irrespective of cultivar 225 kg N ha-1 was the optimum for getting higher tuber yield of potato and cultivar Kufri Himalini was the most efficient in case of N use.SAARC J.

Enrichment of staple food with zinc (Zn) along with solubilizing bacteria is a sustainable and practical approach to overcome Zn malnutrition in human beings by improving plant nutrition, nutrient use efficiency, and productivity. Common bean (Phaseolus vulgaris L.) is one of a staple food of global population and has a prospective role in agronomic Zn biofortification. In this context, we evaluated the effect of diazotrophic bacterial co-inoculations (No inoculation, Rhizobium tropici, R. tropici + Azospirillum brasilense, R. tropici + Bacillus subtilis, R. tropici + Pseudomonas fluorescens, R. tropici + A. brasilense + B. subtilis, and R. tropici + A. brasilense + P. fluorescens) in association with soil Zn application (without and with 8 kg Zn ha−1) on Zn nutrition, growth, yield, and Zn use efficiencies in common bean in the 2019 and 2020 crop seasons. Soil Zn application in combination with R. tropici + B. subtilis improved Zn accumulation in shoot and grains with greater shoot dry matter, grain yield, and estimated Zn intake. Zinc use efficiency, recovery, and utilization were also increased with co-inoculation of R. tropici + B. subtilis, whereas agro-physiological efficiency was increased with triple co-inoculation of R. tropici + A. brasilense + P. fluorescens. Therefore, co-inoculation of R. tropici + B. subtilis in association with Zn application is recommended for biofortification and higher Zn use efficiencies in common bean in the tropical savannah of Brazil.
