A field experiment was conducted to optimise the organic, inorganic and biofertiliser needs for sustained productivity of maize (Zea mays L.). Seven treatments comprising all possible combinations of chemical fertilizer, organic manure (vermicompost, FYM) with and without biofertilizer (Azospirillum and PSB) were laid out in randomized block design with three replications. Different nutrient management practices (organic, inorganic and combined sources of nutrients) significantly influenced the yield attributes, yield and economics of maize crop. Application of 100 % RDF (T1:180-60-50 kg N, P2O5 and K2O ha-1) resulted in significantly higher cob length, girth (17.7 cm, 16.8 cm), cob weight (225 g), no. of kernel rows cob-1 (12.9), no. of kernels row-1 (24.2), kernel weight cob-1 (5207 kg ha-1), kernel yield (5207 kg ha-1) and stover yield (6751 kg ha-1) which was significantly superior over the rest of the nutrient management practices and it was followed by 50% RDF + Vermicompost @ 1t ha-1 + Azospirillum @ 5 kg ha-1 + PSB @ 5 kg ha-1 (T7) and it has given a remarkable yield attributes, kernel (4683 kg ha-1) and stover yield (6394 kg ha-1) which is in turn in parity with 50% RDF + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 +PSB @ 5 kg ha-1 (T6) and significantly superior to rest of the treatments. The highest net returns (₹ 59920 ha-1) and benefit-cost ratio (2.97) were recorded under 100% RDF (T1) followed by application of FYM @ 10 t ha-1 + Azospirillum @ 5 kg ha-1 + PSB @ 5 kg ha-1 (T6) which has registered a B:C ratio of 2.81 which might be due to comparatively better increase in yield with lesser cost over other treatments. Integration of biofertilizer (T6 and T7) has triggered the nutrient uptake mechanism and shown a notable performance in improving yield structures, yield and economics. Long run adoption of combined use of fertilizers and organics expected to match and even excel the sole fertilizer based production strategy.

Field experiment was conducted at Breeder Seed Production farm of Mahatma Phule Krishi Vidyapeeth, Rahuri for two consecutive kharif seasons of years 2010 and 2011 to find out most efficient and economic combination of different organic and inorganic sources of nutrients to increase the productivity of hybrid maize (Zea mays L.) without deteriorating the soil qualities. Application of 25% recommended dose of fertilizers (RDF) in combination with biofertilizers (Azotobacter chroococcum+ phosphate solubilizing bacteria), green manuring with sunhemp and incorporation of compost @10 t/ha improves soil physicochemical properties (viz. decrease in alkaline pH by 0.4, bulk density by 0.04 g/cm and increase in infiltration rate by 0.65 cm/hr). This was also responsible for improving the nutrient status of soil in respect of organic carbon, available N and available P2O5 which were increased by 0.14%, 4.4 kg/ha and 11.7 kg/ha, respectively over the initial nutrient status of soil.

A field experiment was conducted during the winter season of 2013 at a main research field of the School of Agriculture Lovely Professional University, Phagwara, Punjab (India) to study the influence of integrated nutrient management on growth and yield parameters of maize (Zea mays l.) as well as soil physico-chemical properties. The growth parameters (plant height and leaf area) were found to be highest under INM (Integrated Nutrient Management) of poultry manure (PM) or farm yard manure (FYM)and recommended dose of fertilizers (RDF) which are statistically on par but comparatively higher than T₁ (100% RDF). The yield parameters (number of grains per cob, cobs weight per plant, Test weight and stover yield) were significantly higher under INM compared to T₁ (100% RDF). Furthermore, post harvest soil physico-chemical properties (organic carbon and available nitrogen) were significantly improved under T₃ (5t PM + 50% RDF), whereas soil available phosphorus was recorded maximum under T₅ (5t PM + 100% RDF) compared to control and rest of the treatments combination. Therefore, the integration of 50% RDF along with either 5 t/ha FYM or PM or both resulted in maximum maize productivity on par compared with sole used of 100% RDF.
Effect of Biofertilizer and Nutrient Levels on Yield and Nutrient Uptake by Maize (Zea mays L.)
Annals of Agri Bio Research
Low soil fertility is one of the bottlenecks to sustain agricultural production and productivity in India. Nutrient mining by intensive cropping systems and inadequate supply of nutrients have aggravated the situation. Integrated nutrient management (INM) options utilize available organic and inorganic nutrients for sustainable agricultural production and productivity. A field experiment was conducted during kharif at Fertilizer Research Station of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, India. The aim of this study was to see the effect of graded doses of nitrogen with and without Azotobacter inoculation on yield and nutrient uptake by maize crop. Grain yield increased with increasing levels of nitrogen, and maximum grain yield of 4.3 Mg/ha was obtained by use of 150 kg N/ ha with FYM @ 5 t/ha and Azotobacter inoculation. Significant uptake of nitrogen, phosphorus and potassium was recorded under application of 150 N kg/ha over the control. Protein co...

Soil nutrient studies under integrated nutrient management in baby corn (Zea mays L
The Pharma Innovation Journal, 2018
In race towards high production and profit from agriculture, the farmers are adopting abnormal production technologies like heavy and injudicious use of chemical fertilizers that have reduced the factor productivity due to negative effect on soil fertility status. Therefore, it's an urgent need to optimize the integrated nutrient management in different crops including baby corn. The present study was thus carried out during Kharif season 2015 at the Instructional Dairy Farm (IDF), Nagla, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Uttarakhand to study soil nutrient status under the effect of integrated nutrient management. The experimental design was Randomized Block Design with 11 treatments consisting of sole application of NPK fertilizer, sole application of Azotobacter and Azospirillum, and application of Azotobacter and Azospirillum along with NPK fertilizer. The different integrated nutrient management practices had significantly equal organic carbon, however the highest value was recorded at application of 100% NPK and 100% NPK+Azot+Azos. Significantly highest available N and K content was recorded at 100% NPK+Azot+Azos whereas available P was recorded significantly highest at 75% NPK+Azot+Azos in soil after crop harvest. Higher apparent nitrogen and potassium balance was recorded at 100% NPK+Azot+Azos while apparent phosphorus balance was found highest at application of 75% NPK+Azot+Azos. Application of biofertilizers also had better apparent nutrient balance than alone application of chemical fertilizers. The bacterial population differed significantly by different integrated nutrient management practices. The highest bacterial population was recorded at 100% NPK+Azot+Azos followed by 75% NPK+Azot+Azos but both remained non-significant with each other. INM thus showed positive effect on soil chemical and biological properties, and so maintained positive nutrient balance in soil.
