“…The incorporation of green gram residues along with inorganic fertilizers resulted in a significant rice yield increase of 13% over IORA [31]. The highest yield of 4.68 Mg ha −1 in wheat crop was recorded when 50% N (nitrogen) of the recommended dose of fertilizer treatment was replaced with FYM in the rice crop [32].…”

Over years of intensive cultivation and imbalanced fertilizer use, the soils of the Indiansubcontinent have become deficient in several nutrients and are impoverished in organic matter.Recently, this region has started emphasizing a shift from inorganic to organic farming to managesoil health. However, owing to the steadily increasing demands for food by the overgrowingpopulations of this region, a complete shift to an organic farming system is not possible. The rice–wheat cropping system (RWCS) is in crisis because of falling or static yields. The nations of thisregion have already recognized this problem and have modified farming systems towardintegrated nutrient management (INM) practices. The INM concept aims to design farmingsystems to ensure sustainability by improving soil health, while securing food for the populationby improving crop productivity. Therefore, this paper was synthesized to quantify the impact androle of INM in improving crop productivity and sustainability of the RWCS in the context of theIndian subcontinent through meta-analysis using 338 paired data during the period of 1989–2016.The meta-analysis of the whole data for rice and wheat showed a positive increase in the grainyield of both crops with the use of INM over inorganic fertilizers only (IORA), organic fertilizersonly (ORA), and control (no fertilizers; CO) treatments. The increase in grain yield was significantat p < 0.05 for rice in INM over ORA and CO treatments. For wheat, the increase in grain yield wassignificant at p < 0.05 in INM over IORA, ORA, and CO treatments. The yield differences in theINM treatment over IORA were 0.05 and 0.13 Mg ha−1, respectively, in rice and wheat crops. Thepercent yield increases in INM treatment over IORA, ORA, and CO treatments were 2.52, 29.2, and90.9, respectively, in loamy soil and 0.60, 24.9, and 93.7, respectively, in clayey soil. The net returnsincreased by 121% (INM vs. CO) in rice, and 9.34% (INM vs. IORA) and 127% (INM vs. CO) inwheat crop. Use of integrated nutrient management had a positive effect on soil properties ascompared to other nutrient management options. Overall, the yield gain and maintenance of soilhealth due to INM practices over other nutrient management practices in RWCS can be a viablenutrient management option in the Indian subcontinent.

“…In addition, the increase in soil nutrient levels may rely on the type of organic compost added to the soil. The importance of organic compost in enhancing the availability of different soil nutrients may be attributed to several reasons, including the fact that organic compost usually stimulates soil microbial activities and their biomass, thereby enhancing the release of organic nutrients, such as nitrogen and phosphorus, in the soil [18,64]; organic compost acts as a nutrient source, wherein the different inherited ions of organic composts are released into the soil during decomposition and after application in the soil [73]; organic compost can increase cation exchange capacity, which is a very important indicator for retaining nutrients and making them available to plants [25,65]; organic compost releases ions to the soil at a slow and consistent rate, which prevents ions from leaching into ground water [74]; organic compost produces organic acids that have a positive effect in reducing the pH of calcareous soil, which help in releasing phosphorus by the solubilizing action of native soil phosphorus [75,76]; the humic and fulvic acid that are released from organic compost can improve the status of nutrients in the soil by chelating them with phenol and carboxylic groups [77].…”

The primary goal of integrated nutrient management (INM) strategies is to substitute a portion of chemical fertilizers with a more sustainable and environmentally safe organic compost in order to mitigate soil degradation, improve crop production, and protect the environment. Therefore, the present study was conducted to assess the impacts of different INM practices, namely full-dose NPK (T1), compost of cow manure at 5 t ha−1 (T2), compost of poultry manure at 5 t ha−1 (T3), compost of mixed sheep and camel manure at 5 t ha−1 (T4), 50% NPK combined with the mixture of the three types of composts at the rate of 5 t ha−1 (T5) or 10 t ha−1 (T6), and mixture of the three types of composts at the rate of 10 t ha−1 (T7), 15 t ha−1 (T8), or 20 t ha−1 (T9) with or without biofertilizers for each treatment on several physiochemical and biological proprieties of soil and final grain yield of field crops after 2 years of field-scale experiments. The results showed that all INM practices generally significantly (p < 0.05) improved the initial values of all tested soil physiochemical and biological proprieties, whereas improvement was more prominent for the plots treated with T5–T9, compared with those treated with T1–T4. Seed inoculation with biofertilizers also significantly (p < 0.05) increased different soil proprieties by 2.8–12.0%, compared to that of the non-inoculation treatment. Principal component analysis revealed that most soil chemical properties were closely associated with T5–T6 treatments, while most soil physical and biological properties appeared to be more related to T7–T9 treatments. Our results indicated that recycling agricultural wastes into new productive composts and integrating it into appropriate INM practices as shown in T5–T9 treatments may induce favorable changes in soil properties and improve crop production under arid conditions even in the short term.

“…Basmati rice, being a long duration and late-maturing variety, ultimately causes a delay in sowing of wheat. About 40% nitrogen, 30-35% phosphorus, 80-85% potassium, and 40-50 % sulfur (S) present in vegetative parts of a plant which rice acquired during its growth period (8,9) All nutrients which are present in rice straw are lost due to burning (10). This results in severe air pollution and loss of nutrients and organic matter (11).…”

Rice wheat cropping system prevailed in more than fifty percent areas of rice belt of central and upper Punjab. In this area yield of wheat is curtailed every year due to late harvesting of rice crop. In addition to this, lack of machinery for direct sowing of wheat into combine harvested rice is a major limitation for timely wheat sowing due to presence of heavy straw load dropped by the combine harvester. A field experiment was planned and executed during two consecutive years 2017-18 and 2018-19 at Agronomic Research Station Farooqabad to evaluate the various stubble management techniques for the sowing of wheat in a rice-wheat cropping system. The Experiment consist of four treatments Happy seeder (Zero tillage), conventional sowing without burning of rice stubble, Rotavator two times, and Conventional sowing with the burning of rice stubble. The trail was arranged as a Randomized Complete Block Design with four replications having a net plot size of 8 m x 20 m. The Treatments have significant effects on Plant height, Number of productive tillers, 1000- grain weight, and grain yield. Maximum plant height (94.74 and 94.25 cm), numbers of productive tillers/m2 (324.00 and 322.25), 1000-grain weight (36.35 and 36.20 g), grain yield (3780 and 3613 kg/ha), and benefit-cost ratio (2.54 and 2.43) were recorded from the treatment happy seeder (Zero tillage) during both years respectively. It is concluded that the sowing of wheat with a happy seeder (Zero tillage) is an appropriate technique in the rice-wheat cropping system by protecting the environment and soil health from the burning of rice stubbles.
