The present investigation was conducted to study the influence of integrated nutrient management on fertility build up in a Typic Haplaquept soil as well as its effect on yield and quality parameters of rapeseed (Brassica campestris L. var. yellow sarson). Treatments comprised of recommended doses of N, P and K fertilizers (RDF) in presence and absence of FYM along with different doses of S and Zn either alone or in combination. Results revealed that in general, available N, P, K, S and Zn in soil decreased with increase in the period of crop growth. Addition of FYM increased organic carbon content in soils (upto 104.98 g kg-1increase over initial value). Application of elemental S and Zn-EDTA increased SO4-2 content (upto 101.03 kg ha-1 increase over initial value) in S-treated and DTPA extractable Zn content (upto 0.3 mg kg-1 increase over initial value) in Zn-treated systems respectively. Combined application of higher doses of S and Zn along with FYM and recommended doses of N, P and K fertilizers increased N, P, K, S and Zn uptake by rapeseed crop. Highest seed yield (14.2 q ha-1) as well as oil (43.2 %) and protein contents (21.82 %) were recorded in rapeseed which received comparatively higher doses of S and Zn along with FYM and RDF.

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.

PurposeOne of the serious constraints for the integration of organics in soil fertility plans is the release and availability of nitrogen (N) to match the critical growth stages of a crop. The interplay between organic amendment characteristics and soil moisture conditions can significantly affect the nutrient release and availability, especially for dryland crops like wheat. In this study, the effects of integrated nutrient management strategies using diverse qualities of organic amendments on daily N mineralization and its availability to plants during the full growing season of the wheat crop were analyzed in a 10-year experiment.MethodsThe management included (1) F, inorganic fertilizers at 100% rate, compared to a reduced rate of inorganic fertilizers (55% N) supplemented with organic inputs via (2) GM, green manuring, (3) LE, legume cropping and its biomass recycling, (4) WS, wheat stubble retention, (5) RS, rice stubble retention, and (6) FYM, farmyard manure application, during the preceding rice season. Ion exchange resin (IER) membrane strips were used as plant root simulators to determine daily NH4+-N and NO3–-N availability in soil solution during the full wheat growing period.ResultsTotal available N for the full season was in the following order: GM (962 μg cm–2) > F (878 μg cm–2) > LE (872 μg cm–2) > FYM (865 μg cm–2) > RS (687 μg cm–2) > WS (649 μg cm–2). No significant differences were observed in NH4+-N availability throughout the cropping period as compared to NO3–-N which showed significant differences among management at critical crop growth stages.ConclusionLegume biomass incorporation (GM, LE) and farmyard manure (FYM) based management provided the most consistent supply equivalent to or even exceeding 100% inorganic fertilizers at several critical stages of growth, especially at tillering and stem elongation. Integration of organics in management increased nitrogen use efficiency 1.3–2.0 times, with cereal crop residue-based management having the highest efficiency followed by legume biomass incorporation.

To evaluate the effects of integrated nutrient management on growth and yield of BARI tomato-14 and soil fertility, a pot experiment was conducted in the net house of the department of Agricultural Chemistry of Bangladesh Agricultural University, Mymensingh during the period from October 2011 to April 2012. The experiment was laid out in a completely randomized design with 11 treatments and 3 replications. Treatments were control, RDCF100, 75% RDCF, 50% RDCF, 75% RDCF + PM2 t /ha, 75% RDCF + RS3 t /ha, 75% RDCF + PHRD, 50% RDCF + PM3 t /ha, 50% RDCF + RS5 t /ha, 50% RDCF + PHRD, PM3 t /ha + RS5 t /ha + PHRD. Among the treatments applied in combination of PM2 t /ha+ 75% of RDCF excelled in growth trends of morphological characters like plant height, number of branches plant- 1, number of leaves plant-1; available soil P and S. But sole application of RDCF100 recorded higher values for almost all morphological characters namely number of branches plant-1, number of leaves plant-1, fruit diameter, fruit weight plant-1 and yield of tomato following the same trend as seen in combined application of CF and PM. Among the plant hormone applied in combination, RDCF75% + PHRD showed the highest plant height. The more number of leaves plant-1, number of branches plant-1, yield and yield parameters as compared to other treatments were also significantly influenced by application of PH. Combined application of 50% of RDCF+RS5 t /ha increased exchangeable soil K. PM3 t /ha+ RS5 t /ha+ PHRD conserved more organic carbon and total soil N. Results showed that the integrated use of PM, RS along with CF increased the availability of nutrients throughout the growth period by maintaining the long term productivity for sustainable production of tomato.

A field investigation was conducted during the kharif season of 2012 at the experimental farm of School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema Campus, Nagaland. Sole and combined applications of different organic nutrient sources viz., FYM, vermicompost, pig manure, rhizobium and PSB (Phosphate Solubilizing Bacteria) were evaluated in order to optimize organic nutrient management for green gram under rainfed conditions. Results showed that the combined application of rhizobium + PSB + vermicompost @ 0.7 t/ha was found to be the most responsive nutrient management practice recording significantly higher crop growth and yield attributes and ultimately recording the highest seed and stover yields of 369 and 989 kg/ha respectively. Soil available N and K status after harvest as well as seed and stover NPK uptake was found to be significantly higher with combined application of organic manures viz., vermicompost and FYM along with biofertilizers rhizobium and PSB.

The integrated use of chemical and organic fertilizers can help in sustainable and environmentally sound nutrient management of soils. A study was conducted in the farmer’s field of Godaghari, Rajshahi from February to May 2012 to investigate the effect of integrated nutrient management on nutrient uptake by rice cv. NERICA 10 and economization of inputs. Six treatments viz. T1 = Control, T2 = RFD for MYG + cowdung @ 5 t ha-1, T3 = RFD for HYG, T4 = RFD for HYG + cowdung @ 5 t ha-1, T5 = RFD for HYG + cowdung @ 5 t ha-1 based on IPNS, and T6 = RFD for HYG + 10% excess fertilizer of HYG were used. The experiment was laid out in a randomized complete block design with three replications. Results showed that the uptake of N, P, K, S, Ca and Mg by both grain and straw of rice were statistically significant due to use of integrated nutrient management. The highest nutrient uptake was recorded from the treatment T5 and the lowest value was obtained from control. Combined application of cowdung @ 5 t ha-1 along with recommended chemical fertilizers based on IPNS was more economic compared to other treatments because maximum benefit cost ratio was calculated from this treatment. The overall results suggest that integrated nutrient management can be used as an alternate option of chemical fertilization to achieve maximum yield, nutrient uptake and cost of return for rice cv.

A field experiment was conducted in Vertisols at Bijapur during 1994-96 to study the effect of tillage practices and integrated nutrient management on winter sorghum yield and soil nutrient availability. The increase in winter sorghum yield with deep tillage over medium and shallow tillage was 27 and 57% in 1994-95 as compared to 18 and 34% in 1995-96. Deep tillage resulted in 22 and 45% higher yield as compared to medium and shallow tillage in the pooled data. This was mainly due to conservation and increased availability of moisture and nutrients, i.e. N, P and K. The higher availability of nutrients in the topsoil (0-0.15 m) as compared to the subsoil (0.15-0.30 m) was due to the application of nutrients in the topsoil layer and the higher rate of mineralization. Among the organic materials applied, Leucaena loppings at 2.5 t ha-1 led to a significantly (9%) higher yield (1636 kg ha-1) over vermicompost (1500 kg ha-1) and was on par with farmyard manure (1572 kg ha-1) in the pooled data and during both years of the study. The higher percentage increase in grain yield with Leucaena application was due to the better moisture conservation and availability of major nutrients, i.e. N, P and K. Winter sorghum responded significantly to N application at 25 kg ha-1 in 1994-95, whereas in 1995-96 and in the pooled data the response varied up to 50 kg N ha-1. In the pooled data, the grain yield increased by 17 and 24% with the application of 25 and 50 kg N ha-1 compared with the control. The higher yields obtained with the application of nitrogen were due to the better availability of nutrients, especially N, as these soils are low in available N.

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).
