A field study was carried out during rabi seasons in 2017-18 and 2018-19 after harvest of rice to reveal the residual effect of integrated nutrient management on nodulation, yield, quality and available nutrient status in soil after harvest of greengram at Instructional Farm of College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar. The maximum number of root nodules/plant at 30 DAS and 45 DAS in greengram (5.86, 6.19 and 12.49 and 12.94in 2017 and 2018 respectively) were recorded in the subplot treatment of 75% RDF+ rhizobium + PSB and lowest values were obtained in 75% RDF treatment. Similarly in main plot, residual effect of 50% RDF+50% RDN through FYM showed significantly higher number of root nodules/plant during both the years of study which remained at par with 75 % RDF+ Green manuring. Lowest values were obtained from only RDF treatment. Residual effect of 50 % RDF+50 % RDN through FYM showed significantly higher protein % (24.2 and 24) and protein yield (194.3 and 196.2) during both the years of study which remained at par with 75 % RDF+ Green manuring treatment. Residual effect of 75 % RDF+ Green manuring treatment recorded higher increase in soil organic carbon (4.87 g/kg), available N(225.7 kg/ha), Available P (26.2 kg/ha) and available K (296.0 kg/ha) than all other treatment combinations. The residual treatment 50% RDF+25% RDN through FYM recorded the lowest values of soil nutrient status after harvest of greengram. Similarly the sub plot treatment receiving 75% RDF+ Rhizobium+ PSB recorded significantly higher soil organic carbon (4.67 g/kg), available N(217.1 kg/ha), Available P (22.8 kg/ha) and available K (291.8 kg/ha) than 100% RDF and 75% RDF.

Integrated nutrient management (INM) is a widely recognized tool to ensure sustainable crop productivity while preserving soil fertility. The addition of organic manures in soil has been evidenced to improve soil characteristics, in addition to improving nutrient availability. The soil samples, with five treatment combinations of chemical fertilizers with farmyard manure (FYM), were collected from a 17-year-old field experiment conducted at PAU, Ludhiana to investigate the effect of INM on the buildup of organic carbon (OC), microbial community, soil nutrient status and improvement in soil physical properties under the maize–wheat cropping system. The INM technique enhanced the OC content (0.44 to 0.66%), available N (152.8 to 164.9 kg ha−1), P (22.8 to 31.4 kg ha−1) and K (140.6 to 168.0 kg ha−1) after 17 years. The DTPA-extractable and total micronutrients (Zn, Cu, Fe, and Mn) status also improved significantly with FYM supplementation. The organic source, coupled with inorganic fertilizers, improved the water holding capacity, total porosity, soil respiration, microbial biomass C, microbial biomass N, and potentially mineralizable N. However, pH, EC, and bulk density of soil decreased with the addition of FYM, coupled with chemical fertilizers.

An experiment was conducted to study the effect of integrated nutrient management in scented rice and its residual effect on pea under paira cropping system at Regional Research and Technology Transfer Station (RRTTS), Bhawanipatna, Kalahandi, Odisha during 2015-16 and 2016-17. Twelve treatment combinations comprising of T1 - FYM @ 10 t ha-1 + vermicompost @ 2.5 t ha-1 + neem cake @ 2.5 q ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T2 - STBFR (Soil test based fertilizer recommendation 75 : 30 : 20 kg N:P2O5: K2O ha-1), T3 - STBFR + FYM @ 5 t ha-1, T4 - STBFR + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T5 - STBFR + Zn @ 5 kg ha-1, T6- STBFR + S @ 20 kg ha-1, T7- STBFR + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T8- STBFR + FYM @ 5 t /ha + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T9 - STBFR + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T10 - STBFR + FYM @ 5 t ha-1 + Azospirillum @ 5kg ha-1+ PSM @ 5kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T11 - Farmers practice (only chemical fertilizer @ 40 : 20 : 20 kg N : P2O5 : K2O ha-1), T12 - STBFR + vermicompost @ 2.5 t ha-1 were tried in RBD with three replications. The soil of the experimental site was black cotton type having pH- 6.11 , O.C.- 0.72 %, E.C- 0.004 (dS m-1), available N -175.9 kg ha-1 (low), available P-36.7 kg ha-1 (medium) and available K- 283.6 kg ha-1 (high). Geetanjali was the test variety for rice and Azad Pea-1 for pea. Application of STBFR (75 : 30 : 20 kg N : P2O5 : K2O ha-1) + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 (T10) to medium duration aromatic rice (var. Geetanjali) produced higher rice grain yield (4065 kg ha-1) and pea seed yield (1044 kg ha-1) from aromatic rice -pea paira cropping system. However, application of STBFR + FYM @ 5 t ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 producing grain yield (3944 kg ha-1) and pea seed yield 977 kg ha-1 is another option. Application of STBFR (75 : 30 : 20 kg N : P2O5 : K2O ha-1) + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 (T10) recorded maximum gross return (Rs. 1,26,991 ha-1) , net return (Rs. 80,146 ha-1) and B : C ratio of 2.71. The increase in rice equivalent yield (REY) in this treatment was 51.4% higher than the farmer practice i,e., application of chemical fertilizers alone (40 : 20 : 20 kg N : P2O5 : K2O ha-1).

A field experiment was conducted at Mithapur Farm, Patna Campus of the Rajendra Agricultural University, Bihar, India, with rice (cv. Mahsoori) and wheat (cv. UP 262) during 1992–96 in order to assess the integrated effect of chemical fertilizer (NPK) with farmyard manure (FYM) and blue-green algae (BGA) on grain yield and nutrient availability on a Typic Haplaquant. Both rice and wheat yields continued to increase significantly with increasing NPK level up to 100% of the recommended rate. However, maximum yields of rice and wheat were obtained where the recommended rate of NPK was applied along with FYM and BGA. The organic carbon content of the soil decreased up to the rate of 50% of the recommended NPK, either alone or in combination with FYM, BGA, or FYMM+BGA. Available soil nutrients were enhanced up to rates of 75% of the recommended NPK dosage, alone or with FYM, BGA, or FYMmp;plus;BGA, compared with initial values. The maximum build-up of available N, P, and K was measured under integrated use of 100% NPK along with FYM and BGA.

Long-term effect of nitrogen substitution (25 to 50%) through different organics, viz., FYM (farm yard ma-nure), GM (green manure) and WS (wheat straw) on crop yield, nutrition and physico-chemical properties of soil was studied under rice-wheat system. The data of long term experiment revealed that maximum grain yield of 46.83 qha-1 in wheat was obtained when 100% RDF applied through mineral fertilizers after 50% N of RDF being substituted with FYM in rice. Grain yield of wheat declined under control and sub-optimal fertilizer inputs (50% or 75% recommended fertilizer NPK), whereas positive yield increment was observed under treatments receiving organic supplements. The analysis of soil samples showed that soil pH reduced from initial value of 7.40 to 7.22, organic carbon build-up from 0.46% to 0.76%, available N from 194.00 to 225.95 kgha-1 available P2O5 from 23.60 to 49.54 kgha-1 and available K2O from 155.00 to 189.95 kgha-1 However, available Sulphur and DTPA-Zn increased from 7.74 to 14.41 kg ha-1 and 0.75 to 1.37 mg kg-1 respectively due to long-term (29 years) integrated nutrient management practices under rice-wheat system in alluvial soil. In conclusion, substitution of 50% and 25% N of RDF to rice through organics either FYM / Green manure / Wheat straw significantly increased the crop yield and nutrient uptake of wheat as well as build up the organic carbon, available N, P2O5, K2O, Sulphur, DTPA extractable Zn, Cu, Fe and Mn of post harvest soil after 29 years of the experiment.

The field experiments were conducted in Agronomy Department Farm, College of Agriculture, Dapoli. Dist. Ratnagiri during Kharif seasons to study the “Nutrient status of soil after the harvest of pigeonpea as influenced by Intigrated nutrient Management”. Results showed that available N and P content of soil after harvest of pigeonpea were improved due to all the nutrient management treatments over their respective initial values. Application of 75 % RDF + Two foliar sprays of nutrients (Potassium nitrate 1% + DAP 1% + Boron 500 ppm at flowering and 20 days after first spray) + Biofertilizers (Rhizobium +PSB) and RDF + Biofertilizers (Rhizobium + PSB) remained at par and both the treatments significantly improved the available N and P status of soil after harvest of pigeonpea crop over rest of the nutrient management treatments. the values were rather higher compared to their initial levels indicating the increased production of pigeonpea without reduction in soil fertility.

Eight treatment combinations comprising of K1: RDF i.e.,120:60:60 kg N:P2O5:K2O ha-1 (1/3rd N each at transplanting (TP), active tillering (AT) and panicle initiation (PI), K2:50 % RDF (1/3rd N each at TP, AT and PI) + FYM 5 t ha-1, K3:75 %RDF (1/3rd N each at TP, AT and PI) + FYM 5 t ha-1 , K4:100 % RDF (1/3rd N each at TP, AT and PI) + FYM 5 t ha-1, K5:100% RDF (½ N at TP, ¼th N at AT, ¼ th N at PI) + FYM 5 t ha-1 , K6:100 % RDF (¼th N at TP, ½ N at AT, ¼ th N at PI) + FYM 5 t ha-1, K7:50% RDF (1/3rd N each at TP, AT and PI) + FYM 10 t ha-1 and K8: FYM 5 t ha-1 + Vermicompost (VC) 2.5 ha-1 + Azospirillum 5 kg ha-1 + PSB 5 kg ha-1 were applied to hybrid rice var. Ajay grown under SRI method during kharif season and during rabi season mustard was grown taking the eight kharif season plots as main plot and three nutrient management practices viz., R1:100% RDF (40:20:20 kg N:P2O5:K2O ha-1), R2: 50% RDF + Azotobacter and R3-control (no fertilizer) in sub-plot and replicated thrice. The results revealed that application of 100% RDF + FYM 5 t ha-1 to rice registered significantly higher grain (7545 kg ha-1) and straw yield (7241 kg ha-1) of rice and higher seed yield (806 kg ha-1), stover yield(1423 kg ha-1), harvest index (36.3%) of subsequent mustard crop and system rice equivalent yield (9629 kg ha-1). Application of 50% RDF with BF to mustard recorded higher soil organic carbon and pH than RDF and control. The decrease in bulk density was more in the plots applied with 50% RDF+10t FYM to kharif rice (1.38 Mg m-3) and 50% RDF + BF to rabi mustard (1.41 Mg m-3). The available N, P and K content of soil increased to 237.6, 17.1 and 374.9 kg ha-1 from its initial value 148.2, 12.7 and 352.4 kg ha-1, respectively, at the end of second year with application of 50% RDF + BF to mustard.

A field experiment was conducted during kharif 2011 on experimental farm of the College of Post Graduate Studies (CAU–Imphal), Umiam (Meghalaya) to evaluate the effect of integration of green manuring, FYM and fertilizers as integrated nutrient management (INM) practices on growth and developmental behaviour of quality protein maize cultivar QPM 1. The data revealed that comparatively higher amount of primary nutrients were added in green manured maize plots in comparison to non green manured treatments. Green manuring also left a positive response on plant height, CGR, RGR leaf area, and dry matter accumulation in plants though the difference between green manured and non-green manured treatments was at par. Treatments 75 % RDF + 5 t FYM ha-1, 50 % RDF + 7.5 t FYM ha-1, 100 % RDF ha-1 and 75 % RDF + 2.5 t FYM ha-1 recorded significantly higher values of all the above said growth parameters over 50 % RDF + 5 t FYM ha-1 and control treatments. At all stages of observations, the maximum dry matter was associated with RDF (recommended doses of fertilizers) which was at par with 75 % RDF + 5 t FYM ha-1, but significantly higher over the plant dry weight recorded from all remaining treatments. A Significant difference in CGR at 30 – 60 and 60 – 90 DAS stage and in RGR at 90 DAS - harvest stage was observed due to various combinations of recommended dose of fertilizer with different doses of FYM. Number of days taken to attain the stages of 50% tasselling, silking and maturity did not differ significantly due to green manuring. However, treatment 75 % RDF + 5 t FYM ha-1 took significantly lesser number of days for these stages than other treatment combinations. The superiority of the treatment 75 % RDF + 5 t FYM ha-1 indicated a possibility of substituting 25% of RDF with 5 t FYM ha-1 without any loss in dry matter accumulation in plants of the quality protein hybrid maize in mid-hill ecosystems of Meghalaya.
