“…The rice (Oryza sativa L.)-wheat (Triticum aestivum L.) system (RWS) occupying around 13.5 million hectares area in South Asia is the spine of social and economic growth of millions of people [1,2]. The RWS remains the mainstay of cereal production by contributing 23% of food grains [3]. However, the system has begun to show signs of fatigue with yield plateau and soil health decline.…”

The rice-wheat system (RWS), managed over 10.5 Mha in the Indo-Gangetic Plains of India suffers from production fatigue caused by declining soil organic matter, multi-nutrient deficiencies and diminishing factor productivity. We, therefore, conducted a long-term field experiment (1998–1999 to 2017–2018) in Modipuram, India to study the effect of continuous use of farmyard manure (FYM) as an organic fertilizer (OF), mineral fertilizers applied alone (RDF) and their combination (IPNS), as well as the inclusion of forage berseem (IPNS+B) or forage cowpea (IPNS+C) on crop yield, soil health and profits. The long-term yield trends were positive (p < 0.05) in all treatments except the control (unfertilized) in rice, and the control and RDF in wheat. Although the yields of rice, wheat and RWS were highest under IPNS treatments (IPNS, IPNS+B, IPNS+C), the maximum annual yield increase in rice (9.2%) and wheat (13.7%) was obtained under OF. A linear regression fitted to the yield data under different IPNS options revealed a highly significant (p < 0.001) annual yield increase in rice (5.1 to 6.6%) and wheat (6.8 to 7.7%) crops. Continuous rice-wheat cropping with RDF brought an increase in soil bulk density (Db) over the initial Db at different soil profile depths, more so at depths of 30–45 cm, but inclusion of forage cowpea or berseem in every third year (IPNS+B or C) helped to decrease Db, not only in surface (0–15 cm) but also in sub-surface (15–30 and 30–45 cm depth) soil. Whereas soil organic carbon (SOC) increased under OF, IPNS and IPNS + legume (B or C) treatments, it remained unaffected under RDF after 20 RW cycles. The inclusion of legumes along with IPNS not only helped to trap the NO3–N from soil layers below 45 cm but also increased its retention in the upper soil (0–15 cm depth). On the other hand, RDF had a higher NO3–N content in the lower layers (beyond 45 cm depth), indicating downward NO3–N leaching beyond the root zone. A build-up of Olsen-P was noticed under RDF at different time intervals. The soil exchangeable K and available S contents were maximal under OF and IPNS options, whereas a decline in DTPA extractable-Zn was recorded under OF. Overall, RWS economics revealed that OF treatment involved the maximum cost of cultivation (US$1174 ha−1) with the least economic net return (US$1211 ha−1). Conversely, IPNS + legume (B or C) had lowest cost of cultivation (US$707 to 765 ha−1) and a significantly higher (p < 0.05) net return (US$2233 to 2260 ha−1). The study, thus, underlines the superiority of IPNS over RDF or OF; the inclusion of legumes gives an added advantage in terms of production sustainability and soil health. Further studies involving IPNS ingredients other than FYM is needed to develop location-specific IPNS recommendations.

“…The effect of various treatments on straw yield could be arranged in order of T6>T3>T5>T4>T2>T1 and values were 91.75, 86.25, 79.25, 75.75, 70.75 and 62.00 q ha-1 respectively. "The beneficial effect of organic manure (FYM) on yield might be due to an additional supply of plant nutrients as well as an improvement in the physical and chemical properties of soil" Satish et al and Satyanarayana et al [4,6]. It is concluded that the application of 50% NPKS + 10 ton FYM ha-1 + Bio-fertilizers PSB + BGA not only produced a higher yield of rice but also enhanced soil fertility as compared to inorganic fertilizers alone.…”

“…"Rice is the only cereal crop that can grown for long periods of time in standing water, 57% of rice is grown in irrigated land, 25% on rainfed Introduction lowland, 10% on the upland, 6% in deep water, and 2% in tidal wetland. As the land area decrease with time, increasing land use intensity with inadequate and imbalanced use of chemical fertilizers with little or no use of organic manure caused severe fertility deterioration resulting in stagnating or even declining crop productivity" (Shormy et al 2013) [4,5].…”

The present study conducted entitled, “Effect of Integrated use Organic manure and Bio-fertilizers on crop productivity under Rice (Oryza sativa L.) crop". Involved field trial conducted during Kharif season of year 2016-17 followed by laboratory analysis of the plant and soil samples in the Department of Soil science & Agriculture Chemistry, Udai Pratap Autonomous College, Varanasi (U. P). All grasses were removed from the experimental plots and soil samples have been taken from each replication plots at 30 DAT, 60 DAT and at harvesting. The experiment was conducted under randomized block design (RBD) with six treatment combinations. Treatments were replicated thrice making the total number of 18 plots. The effect of various treatments on dry matter production could be arranged in order of T6>T3>T5>T4>T2>T1 and the values were 70.25, 62.15, 59.45, 43.40, 41.25 and 35.59 gm-1 row length, respectively. Application of fertilizers alone or in combination with F.Y.M increased grain and straw yield of rice significantly over control. Further, the yield was significantly superior under the use of organic manure and bio-fertilizers over the sole use of chemical fertilizers. On the basis of data, the superiority of the treatments may be arranged as T6>T3>T5>T4>T2 and T1. Like dry matter yield, rice grain and straw yield was also highest in treatment where 50% NPK was substituted through FYM to rice crop. The integrated use of fertilizers with FYM and bio-fertilizers might have added huge quantity of organic matter in soil that increased grain and straw yield. In general, higher number of tillers (15.25 m-1 row length), plant height (92.50 cm), dry matter at 60 DAT (70.25 gm-1 row length), grain yield (46.25 Qha-1 ) and straw yield (91.25 Qha-1 ) obtained with T6 treatment followed by T3>T5>T4>T2>T1 (control).

“…Soil test based NPK application in the soil also recorded higher available nitrogen content in the soil as the initial soil nitrogen content comes under low category (186 kg ha -1 ), hence under this treatment 30 % extra nitrogen was applied to soil. Hence, percent contribution from fertilizer will be higher than soil source in any other treatment, besides higher amount of N applied at 60 DAS as split might maintain a higher amount of nitrogen in the soil [13]. Critical observations of the data at different stages of crop revealed that soil available nitrogen declined from 15 DAS to 60 DAS and then it increased slightly in after harvest [14].…”

A field experiment was conducted at College Farm, Agricultural College, Polasa, Jagtial, Professor Jayashankar Telangana State Agricultural University. The study was aimed at identifying the effect of integrated nutrient management on nutrient availability in soil. The field experiment was laid out in a randomized block design with nine treatments replicated thrice. The treatments includes T1: 100% Recommended dose of Fertilizer (RDF), T2: 100% RDF + FYM (Farm Yard Manure), T3: 100% RDF + FYM + Biofertilizer consortium, T4: 75% RDF, T5: 75% RDF + FYM, T6: 75% RDF + FYM + Biofertilizer consortium, T7: Soil Test Based (STB) NPK, T8: 75% STB NPK + FYM and T9: 75% STB NPK + FYM + Biofertilizer consortium. The results of the experiment revealed that integrated nutrient management significantly influenced the availability of various nutrients at different stages of the crop. Significantly higher nitrogen and its inorganic fractions, phosphorous, potassium and sulphur availability was recorded with the integrated application of 75% STB + FYM + Biofertilizer consortium which was comparable with an application of Soil Test Based NPK, 100 % RDF + FYM + Biofertilizer consortium, and 75% STB NPK + FYM. The lower available nitrogen, phosphorus, potassium, sulphur, ammonical and nitrate nitrogen were recorded under the treatment of 75 % RDF.
