AbstractA field experiment was conducted to study the long-term effects of nutrient management practices on micronutrient concentrations in soil and their uptake by crops under a long-term rice–wheat cropping system. The treatments comprised different combinations of N, P, K, Zn and farm yard manure (FYM), used as nutrient management practices. After 25 years of continuous cropping, the higher grain yields and uptake of iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn) were obtained when FYM was applied along with mineral sources of nitrogen, phosphorus and potassium (NPK) when compared to mineral sources of NPK alone. The residual effect of FYM, applied to rice, on the yield of subsequent wheat was significant. The application of mineral NPK with FYM recorded higher diethylene triamine penta acetic acid extracted (DTPA)-Fe, Mn and Cu concentrations in the soil compared to any other treatment. The plots with Zn application showed higher DTPA-Zn concentration in the soil compared to any other treatments. The available Fe, Mn and Cu in the soil were higher than their critical limits and the soil was low in Zn where inorganic fertilizers were applied alone (without Zn). Integrated application of mineral NPK and FYM to the rice crop and mineral NPK to wheat was found to be the best nutrient management practice in producing higher yields of rice and wheat and improve long-term soil micronutrient concentrations.

A field experiment was conducted to evaluate the effect of land management practices and residual effect of nutrient management practices of rice on the performance of subsequent wheat crop in the rice-wheat cropping system in Agriculture and Forestry University (AFU), Rampur, Chitwan, Nepal during June 2018-March 2019. The experiment was executed in a split-plot, included two establishment methods viz. (i) conventional tilled dry direct-seeded rice followed by (fb) zero tillage wheat (CT-DDSR fb ZT) (ii) puddled transplanted rice followed by conventional tillage wheat (Pu-TPR fb CT) as main plot treatments, and four nutrient management practices: (i) 100% recommended dose (100% RDF; 150:45:45 and 80:60:40 kg N, P2O5, and K2O ha-1 respectively for rice and wheat), (ii) Residue retention @ 5 t ha-1 of wheat on rice fb residue of rice on wheat + 75% RDF of each crop (RR +75%RDF), (iii) Nutrient expert (NE) dose (140:56:53; 140:60:45 kg N, P2O5, and K2O ha-1 for rice and wheat respectively), (iv) Brown/green manuring of Sesbania in rice fb rice residue @ 3.5 t ha-1 in wheat +75% RDF of each crop (BM/GM fb R+75% RDF) as subplot treatments with three replications. The variety of wheat ‘Bijay’ was sown @120 kg ha-1 with spacing 20 cm × continuous. The data on phenology, yield, yield attributes, and economics were recorded and analyzed by R studio. The study revealed that none of the yield attributes and yield of wheat were significantly influenced by the establishment methods. Significantly more effective tillers (281.94 m-2) and grains per spike (44.48) and higher straw yield (5.95 t ha-1) were recorded under NE dose. The grain yield of wheat was 21% and 16% more under NE dose and BM/GM fb R+75% RDF respectively compared to 100% RDF. CT-DDSR fb ZT wheat had slightly less net returns (NRs. 4523 ha-1) than Pu-TPR fb CT-wheat. NE dose was the most profitable. Hence, rice establishment methods were indifferent but NE dose was the best nutrient management practice for better production and profitability for the wheat in the rice-wheat system.

SUMMARYIdentification of climate-smart nutrient management practices will overcome the ill effects of extreme climate variability on agricultural production under projected climate change scenarios. The rice–wheat cropping system is the major system used in India: using long-term yield data from Integrated Nutrient Management experiments on this system, the present study analysed trends in weather parameters and grain yield under different nutrient management practices. Twelve treatments with different combinations of inorganic (chemical fertilizer) and organic (farmyard manure (FYM), green manure (GM) and crop residue) sources of nutrients were compared with farmers’ conventional practices. A significant increasing trend was noticed for rainfall during the rice season at Kalyani and Navsari, of the order of 137·7 and 154·2 mm/decade, respectively. The highest increase in maximum temperature was seen at Palampur (1·62 °C/decade) followed by Ludhiana (1·14 °C/decade). At all the sites except Ludhiana and Kanpur, the yield of the rice–wheat system showed an increasing trend ranging from 0·08 t/ha/year in Jabalpur to 0·011 t/ha/year in Navsari, under the recommended dose of inorganic fertilizer application. A significant decreasing trend of 0·055 t/ha was found in Ludhiana. For most of the sites, a combination of half the recommended dose of inorganic fertilizer and either FYM or GM to provide the remainder of the N required was sufficient to maintain productivity. The top three climate-resilient integrated nutrient management practices were identified for all the study sites. Thus, the present study highlights the adaptive capacity of different integrated nutrient management practices to rainfall and temperature extremes under rice–wheat cropping system in distinctive agro-ecological zones of India.

The Mean

We analyzed data from a long-term rice-potato-groundnut cropping sequence to evaluate the effects of different nutrient management practices on yield trends, economics and soil fertility of the system. In this study, most of the organic and integrated treatments showed significantly higher mean system yield in terms of rice-equivalent yield (REY) of the 13th and 14th crop cyclethan that of with purely inorganic source. Highest mean rice-equivalent system yieldwas obtained in the treatment with 33% of recommended N each from FYM, vermicompost and Neem cake along with Azospirillum, Azotobacter, Rhizobium and PSB (14.96 t ha-1). In contrast with the yield result, purely inorganic treatment showed better performance compare to all other organic and integrated treatments from the economical point of view during last two 13th and 14 th cropping year. The organic nutrient-management packages increased the mean soil organic carbon and soil macronutrients (available N, P and K) at the end of 13th and 14 th cropping system cycle over the control (fallow land) and the buildup was maximum in the soil, applied with 33% of recommended N each from FYM, vermicompost and Neem cake along with Azospirillum, Azotobacter, Rhizobium and PSB (0.98%, 301.8, 61.1 and 173.3 kg/ha for organic carbon, N, P and K). The mean microbial population after thirteenth and fourteenth cropping year in terms of colony forming units increased in a higher rate in soils with organic nutrient supply system (bacteria 3.7 to 14.5 cfu g-1, fungi 3 to 12.3 cfu g-1) compared to the control as against the respective increases of 1.2 cfu g-1 and 1.8 cfu g-1 in the soils receiving nutrients through chemical fertilizers. Application of 33% of recommended N each from FYM, vermicompost and Neem cake along with Azospirillum, Azotobacter, Rhizobium and PSB was the best organic nutrient management practice compare to other studied management practices for rice–potato–groundnut cropping system in new alluvial zone of West
