A study was conducted in an ongoing experiment under AICRP on micronutrients at nursery jhilli of RPCAU, research farm. The experiment consisted of thirteen treatments, of which twelve combinations were of four doses of zinc (Zn) (2.5, 5.0, 7.5 and 10 kg ha-1), three frequencies (only once, alternate year and every year) of application along with control with the no-zinc application. Rice and wheat crops were grown in succession with the recommended dosages of fertiliser viz. 120:60:40 of N: P2O5: K2O applied as Urea, DAP, and Potash, respectively. Surface soil samples (0-15 cm) were collected after the harvest of the wheat crop in the year 2018, i.e. after completion of six years of the experiment, and analysed for soil physical and chemical properties. The availability of nitrogen, sulphur, organic carbon content and aggregate stability increased, and the bulk density, phosphorous availability decreased with increasing doses and zinc application rates. No effect on soil availability of potassium, pH and EC. The treatment T7 i.e., application of zinc @ 7.5 kg Zn ha-1 in alternate year application was the best treatment with regards to yield of rice-wheat cropping (982.9 q ha-1) and also for good physical and chemical properties of the soil.

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.

At 15 sites in the cereal belt of New South Wales and Victoria, wheat after lupin or pea produced more biomass and had a greater nitrogen (N) content than wheat after wheat or barley; on average these crops assimilated 36 kg N/ha more. The improved wheat yield after lupin averaged 0 . 9 t/ha and after pea 0.7 t/ha, increases of 44 and 32% respectively. The responses were variable with site, year and legume. Soil available N was increased by both lupin and pea and the levels of surface inorganic N measured at the maturity of first year crops was often related to N in wheat grown in the following year. Of two possible sources of additional N for wheat after legumes, namely mineral N conserved in soil by lupin or pea (up to 60 kg N/ha) and the total N added in the residues of these legumes (up to 152 kg N/ha), both were considered significant to the growth of a following wheat crop. Their relative contribution to explaining variance in wheat N is analysed, and it is suggested wheat may acquire up to 40 kg N/ha from legume stubbles. Non-legume break crops also increased subsequent wheat yield but this effect was not as great as the combined effect of added N and disease break attained with crop legumes.

Ashes from agricultural biomass in agro-based industries have been found to have most of the plant nutrients except nitrogen and sulphur but are treated as waste material. The present study was conducted to evaluate the potential of biomass ashes as source of P and their effect on bioavailability of micronutrients in wheat crop. We conducted the pot experiment at glass house of the Department of Soil Science, Punjab Agricultural University, Ludhiana, India. The experiment consisted of combinations of four P sources [bagasse ash (BA), rice husk ash (RHA), rice straw ash (RSA), fertilizer P (Fert-P)] supplying P at three levels (10, 20 and 30 µg g-1) along with one zero-P control. This experiment was laid out in completely randomized design (CRD) having three replications. Application of P through RSA produced significantly higher grain yield (14.3 g pot-1) than BA (12.8 g pot-1) and RHA (12.9 g pot-1) but statistically at par with Fert-P (13.5 g pot-1). Grain Zn content decreased maximum than other micronutrients with application of P from all sources, hence maximum increased P/Zn ratio. Phosphorus applied from all the biomass ashes significantly increased biomass and yield over control. With increase in P application, micronutrients content in grain was significantly decreased, hence decreased bioavailability of micronutrients in wheat grain.

Zinc (Zn) is an essential micronutrient for growth and development of almost all organisms and its deficiency severely affects the health of plants, animals and humans. In order to investigate the enrichment of Zn in cereals a pot experiment was performed in two contrasting rice varieties viz., PD16 (zinc efficient) and NDR359 (zinc inefficient) under different levels of zinc regimes such as control (0 Zn), soil application (5 mg Zn/kg soil tagged with 3.7 MBq of <sup>65</sup>Zn/pot), foliar spray of 0.5% ZnSO<sub>4</sub> at 30, 60 and 90 days (925 KBq of <sup>65</sup>Zn/pot), soil application (5 mg Zn/kg soil tagged with 3.7 MBq of <sup>65</sup>Zn/pot) + foliar spray of 0.5% ZnSO<sub>4</sub> at 30, 60 and 90 days (925 KBq of <sup>65</sup>Zn/pot). Both varieties markedly differ in <sup>65</sup>Zn accumulation and grain Zn content. NDR359 showed poor translocation efficiency and accumulated relatively less <sup>65</sup>Zn in all the plant parts. In both rice varieties, highest concentration of Zn in dehusked grains could be obtained with soil application of Zn + foliar spray of zinc sulphate. Though NDR359, a zinc inefficient variety exhibited poor zinc translocation efficiency yet, it contained more Zn content in grains with husk and dehusked grains than PD16.

A field experiment using various levels of phosphorus, farmyard manure (FYM) and biofertilizers was undertaken at Udaipur during 2001–02 and 2002–03 to observe the direct effect of the treatments on the yield and micronutrient uptake of soybean and their residual effect on the yield and micronutrient utilization of a subsequent wheat crop. The results revealed that the seed/grain yield of soybean and wheat significantly increased with the application of increasing levels of P, FYM and biofertilizers. The integrated use of P, FYM and biofertilizers was able to replace 20 kg P 2 O 5 ha −1 to soybean and 10 kg P 2 O 5 ha −1 to wheat.The application of increasing levels of P, FYM and biofertilizers significantly enhanced the uptake of Zn, Cu, Mn and Fe by soybean and wheat. Among the biofertilizers, dual inoculation with phosphate-solubilising bacteria (PSB) + vesicular arbuscular mycorrhiza (VAM) gave the best performance. The integrated use of P levels and biofertilizers significantly improved the Zn and Fe uptake of soybean. The highest Zn and Fe uptake (125.77 mg kg −1 and 562.03 mg kg −1 , respectively) was recorded with the combined use of 40 kg P 2 O 5 ha −1 + dual inoculation. The application of FYM and P levels resulted in a significant improvement in the organic carbon, CEC, available N and P, porosity and hydraulic conductivity of the soil after the wheat harvest. Among the biofertilizers, dual inoculation led to maximum soil-available P. Phosphorus application gave a significant decrease in the DTPA-extractable Zn and Fe content of the soil after the harvest of wheat. FYM application significantly enhanced the DTPA-extractable Zn, Cu, Mn and Fe contents of the soil.

A field experiment was conducted during the rabi season of 2013-14 and 2014-15 at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur to evaluate the integrated nutrient management on nutrient concentration. The experiment was comprising sixteen  treatments viz. T1- control, T2- 100% RDF,T3- 100% RDF+S, T4- 100% RDF+S+Zn, T5- 100% RDF + S + Zn + bio-fertilizer (Azotobactor+ P.S.B.), T6- 100% RDF + 25% N through F.Y.M., T7- 100% RDF + 25% N through FYM + S, T8- 100% RDF + 25% N through FYM + S + Zn, T9-100% RDF. + 25% N through F.Y.M. + S + Zn + bio-fertilizer  (Azotobactor+ P.S.B.), T10-100% RDF + 25% N through vermi compost, T11- 100% RDF + 25 % N through vermicompost + S + Zn + bio-fertilizer (Azotobactor+ PSB), T12- 75 % RDF T13- 75 % RDF + 25 % N through FYM T14- 75% RDF + 25% N through vermi compost, T15-75% RDF + 25% N through FYM + S + Zn + bio-fertilizer (Azotobactor+ P.S.B.) and T16- 75% RDF + 25% N through vermi compost + S + Zn + bio-fertilizer (Azotobactor+ P.S.B.). Contents of N, P, K, S and Zn. Increased linearly and non-significantly except N content in grain and straw and Zn content at all the stages of crop growth in comparison to control. Highest concentration of N, P, K, S and Zn at late tillering, milking and at harvest in grain and straw was recorded with T11 (100% R.D.F. + 25% N through vermicompost+S + Zn + bio- fertilizers (Azotobactor+P.S.B.) followed by T9 (100% R.D.F. + 25% N through F.Y.M. + S + Zn+bio-fertilizers   (Azotobactor+P.S.B.) and minimum at control (T1) during both the years. Integration of sulphur, zinc, bio-fertilizers, FYM and vermicompost with 100% RDF and 75% RDF treatments also influences N, P, K, S and Zn content at all the stages of crop growth during both the years. It was also observed that integration of sulphur and zinc showed higher increases and its content also increase the concentration of others nutrients higher with 100% RDF treatments in comparison to 75% RDF treatments. The higher concentration of N, P, K, S and Zn to be attributed to higher availability and synergistic effects of these nutrients to each other at all the stages of crop growth.

A field experiment was conducted during rabi seasons of2017-19 at Panwari village, Agra (U.P.) to assess the effect of integrated potassium management on growth, yield and uptake of nutrient in wheat (Triticum aestivum). The experiment was laidout in a randomized block design with seven treatments and three replications. The results revealed that increasing levels of K fertilizers increased the growth and yield attributes up to 90 Kg K2O ha-1 over control. But the growth and yield attributes 0f wheat were maximum with the application of 150 Kg N + 60 Kg P2O5 + 60 Kg K2O + 5 t FYM ha-1. Increasing levels of NPK fertilizers increased the yield of wheat grain and straw over control. The maximum yield of grain(5.48 t ha-1) and straw(9.60 t ha-1) were recorded with N150P60K60FYM5. The increases in grain and straw yield with this treatment were 44.2 and 29.7% over control, respectively. The crop quality in respect of content and yield of protein increased significantly with conjoint use of fertilizers and maximum values were recorded with 150 Kg N + 60 Kg P2O5 + 60 Kg K2O + 5 t FYM ha-1 treatment. Increasing levels of NPK fertilizers up to N 150 P 60 K 90 also resulted in higher uptake of NPK by the crop and highest uptake of N, P, K and S by wheat crop was recorded with N150 P60 K60 FYM5 and the lowest in control. The soil organic carbon, available N, P and K content also improved with N150 P60 K60 FYM5 over control and lowest values of these parameters were recorded in control.
