Soil quality deterioration, especially in intensive cropping systems, has become a serious problem for crop productivity; consequently, strategies for sustainable crop production and soil health are urgently required. Experiments on fields were organized to investigate the impact of organic manures on crop productivity, soil physiochemical properties and soil water availability in a maize-based cropping system. The experiment consisted of five treatments, including organic manures (OM) and inorganic nitrogen, phosphorus and potassium (NPK) fertilizers applied separately and in combinations: NPK = 250-150-125 Kg/ha (recommended rate), farmyard manure (FYM) = 16 t/ha, poultry manure (PM) = 13 t/ha, NPK + FYM = 150-85-50 Kg/ha + 8.5 t/ha and NPK + PM = 150-85-50 Kg/ha + 7.0 t/ha. The results showed that the combination of OM with mineral fertilizers increased crop productivity, fertilizer use efficiency and yield sustainability indices over the treatments amended with sole application ...
Review Article INTEGRATED NUTRIENT MANAGEMENT-A NEED OF HOUR FOR SUSTAINABLE MAIZE YIELDS
International Journal of Agriculture Sciences, 2022
The integrated nutrient management (INM) focuses towards the maintenance and suitably adjusting the soil fertility besides providing the desirable plant nutrients for their growth and development so to have a sustained and regular yield without affecting the fertility and health of soil. It also plays an important role to cut down the requirement of the chemical fertilizers thereby helping to protect from the environmental pollution. For the maintenance of soil productivity and fertility the application of balanced dose of nutrients is an essential requirement which can be easily fulfilled with the application of inorganic fertilizers in combination with the organic manure that helps to reduce the dependency over inorganic fertilizers besides maintaining the desirable yield. The integrated nutrient management practices not only help to maintain the soil fertility but also helps to provide food security and enhancing the yield of the different crops hence provides a beneficial effect towards the growth and development of the agriculture sector. So, keeping in view the above facts an attempt has been made to review the importance of integrated nutrient management for improving the yield of maize crop.

Role of Integrated Nutrient Management for Sustainable Maize Production
International Journal of Agronomy, 2021
Boosting crop productivity can be attained through the application of inorganic fertilizer; however, safeguarding the environment for future generations is overbearing especially for continuous increase in the world population. Sustainable crop productivity might be attained through the judicious use of both organic and inorganic fertilizers. The substitution of parts of inorganic fertilizers with organic fertilizer could maintain and sustain soil productivity and improve crop productivity. This paper has reviewed the past research work carried out by various scientists. A comprehensive literature review revealed that integrated nutrient management enhances maize yield, nutrient uptake, and economic return compared with the sole application of organic and inorganic fertilizers.

In modern agriculture the integration of organic and inorganic fertilizers has been proved as the best technique to maximize the nutrient availability to crops for longer period of time and to minimize the essential nutrients loss from rhizosphere soil. However, most of the researchers and farmers are uninformed of that which is the best fertilizer integration ratio and what type of organic manure should be used for obtaining good fertile soil and economical crop yield. In response of the above question the present research experiment was carried out in in kharif season 2018 at Cereal Crop Research Institute (CCRI), Nowshera, KPK, Pakistan to investigate the performance of maize crop in response to different types of organic manures integrated with inorganic nitrogen fertilizer in distinct ratios based on % nitrogen (N). Total 9 treatments were used in the experiment such as T1 (Control=100%N from Urea), T2 (50%N from SSB+50%N from Urea), T3 (50%N from SCB+50%N from Urea), T4 (50%N from PL+50%N from Urea), T5 (50%N from FYM+50%N from Urea), T6 (25%N from SSB+75%N from Urea), T7 (25%N from SCB+75%N from Urea), T8 (25%N from PL+75%N from Urea) and T9 (25%N from FYM+75%N from Urea). The outcomes of the experiment revealed that all the treatments have significantly affected the kernel yield, plant height, 100 kernel weight and ear length while the number of kernel rows was non-significant. Treatments having 1:1 combination (T2, T3, T4 and T5) has far more better results as compared to 3:1 ratio combination (T6, T7, T8 and T9) and 1:0 ratio combination (T1). Among 1:1 treatment the overall performance of treatment T2 (50%N from soya bean straw biochar (SSB)+50%N from urea) was best of all increasing the kernel yield, plant height, 100 kernel weight, ear length and kernel rows per cob up to 54.5%, 15.2%, 16%, 17.7% and 8.1% respectively more than any other treatment. Hence integration of soya bean straw biochar with urea in 1:1 based on %N is advised for maximum yield and better growth performance of maize. Such studies on different cereal and leguminous crops under different soil and climatic conditions is recommended for vast spread application and authorization of results.

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.

Background: Applying inorganic fertiliser can boost crop output, but protecting the environment for future generations is burdensome, especially with the ongoing rise in global population. It is possible to achieve sustainable agricultural yield by using fertilisers, both organic and artificial, in a strategic way. Parts of inorganic fertilisers could be replaced with organic fertilisers in order to preserve and boost soil productivity and increase crop yield. Methods: The two year field experiment was conducted at experimental farm at Lovely Professional University, Phagwara, Punjab during the kharif season 2019-2020 to study the influence of integrated use of organic manures and inorganic fertilizers on physiochemical properties of soil and yield of maize in coarse loamy Typic Haplustept soil with 8 treatments treatments T 1-Control, T 2 (125:60:30) kg ha-1 , T 3-RDF +10 ton farmyard manure ha-1 , T 4-75% RDF+10 ton farm yard manure ha-1 +Vermicompost @ 2 ton ha-1 , T 5-75% RDF+10 ton farmyard manure ha-1 , T 6-50% RDF +10 ton farm yard manure +vermicompost@ 2 ton ha-1 + azotobacter ha-1 , T 7-50% RDF +15 ton of farmyard manure +azotobacter ha-1 , T 8-25 % RDF + azotobacter + vermicompost@ 2 ton ha-1 in RBD design with 3 replications. Result: The soil pH was found highest in T 2 (RDF (125:60:30) kg ha-1) (7.41) whereas highest EC was found in T 2-RDF (125:60:30) kg ha-1 (0.23 dSm-1). The highest bulk density found under T 1 (Control) (1.83 g cm-3) and porosity was highest in T 6 (50% RDF +10 ton farm yard manure + vermicompost@ 2 ton ha-1 + azotobacter ha-1) (36.66%). In T 6 (50% RDF +10 ton farm yard manure + vermicompost@ 2 ton ha-1 + azotobacter ha-1), the highest amount of nitrogen (312.3 kg ha-1), phosphorus (25.6 kg ha-1), potassium (285.33 kg ha-1) and organic carbon (5.6g kg-1) was found. In terms of yield parameters, the grain yield (4223 kg ha-1), straw yield (5266 kg ha-1), harvest index (41.53%) and 1000-seed weight (286.66 gm) was found highest in T 6 (50% RDF +10 ton farm yard manure + vermicompost @ 2 ton ha-1 + azotobacter ha-1). There are significant difference in all the treatements with respect to the physico-chemical properties of soil and yield paramters of maize.

Integrated use of organic and inorganic fertilizers has better effects on crop growth and yield components of crop as well as soil health than alone. The main objective of the study was to find out the impact of integrated nutrient management on yield and soil health in maize-wheat cropping system. The maize crop was harvested when cob sheath turned brownish and grains became hard and grains were separated from cobs by hand shelling. When wheat crop matured and dry plants from net-1 plot area were harvested and threshing was done by using wheat thresher and expressed as t ha. The soil samples were collected from different plots of the experimental field and were analysed for physical (bulk density, hydraulic conductivity) and chemical (organic carbon, available N, P and K) properties. Infiltration rate was measured at the experimental field with the help of double ring infiltrometer. Addition of NPK fertilizer along with organic manure and biofertilizers improved yield and increased organic carbon content, available N, P, K and infiltration rate and hydraulic conductivity of the soil while reducing bulk density. Application of 50% recommended dose of fertilizer + 50% recommended dose of nitrogen produced significantly higher maize grain yield and significantly higher wheat grain yields were recorded with the application of 100% recommended dose of fertilizer over control. Lowest bulk density, highest hydraulic conductivity and infiltration rate were recorded with the application of 37.5% recommended dose of fertilizer + 37.5% recommended dose of nitrogen + biofertilizer to wheat. Application of 50% recommended dose of fertilizer + 50% recommended dose of nitrogen to maize and application of 37.5% recommended dose of fertilizer + 37.5% recommended dose of nitrogen + bio fertilizer to wheat resulted in increased available N by 10.
