“…Following closely behind were the genotypes Sukara Dhan 1 and Him Palam Dhan 1, which exhibited similar yields. Similar finding indicating significantly higher values of biological yield of rice under conventional tillage have also been reported by other workers [ 21 , 38 , 49 ].…”

“…The increased straw production observed in conventional tillage can be attributable to several factors, including better root growth, improved nutrient availability and uptake, and elevated photosynthetic activity, in comparison to natural farming practices. Similar finding indicating significantly higher values of straw yield of rice under conventional tillage have also been reported by other workers [ 21 , 49 , 50 ]. Upon further analysis of the data, it becomes evident that the implementation of the natural farming strategy led to a notable decrease in straw output.…”

“…The observed variations among the genotypes with respect to this metric can be ascribed to their genetic constitution. Similar differences among different rice genotypes were also reported by number of workers [ 37 , 43 , 48 , 49 ].…”

“…The variations in harvest index observed among different genotypes can be ascribed to the genetic composition of these kinds. Other workers have also reported significantly higher harvest index with conventional tillage [ 21 , 43 , 49 ] as compared to other tillage methods.…”

“…Moreover, the sufficient availability of nitrogen and phosphorus is believed to have played a role in facilitating an enhanced and effective translocation of photosynthates to the grains, resulting in the development of larger and heavier grains, and thus, an elevated 1000-grain weight. Other workers have also reported significantly higher 1000-grain weight with conventional tillage [ 43 , 48 , 49 ] as compared to other tillage methods.…”

Background The rice-wheat cropping system is the prevailing agricultural method in the North-Western states of India, namely in the Indo-Gangetic plains. The practice of open burning of rice residue is frequently employed for expedient land preparation, but it has significant adverse impacts on both the environment and human health. These include the emission of greenhouse gases, loss of nutrients, elevated concentrations of particulate matter (PM), and disruption of the biological cycle. This research aims to investigate the implementation of effective management strategies in the rice-wheat cropping system, namely via the use of tillage-based crop cultivation techniques, stubble retention, and integration approaches. The objective is to enhance soil health features in order to augment crop yield and improve its attributes. Results The research was carried out using a split plot experimental design, consisting of three replications. The main plot consisted of four different cultivation methods, while the subplot included three genotypes of both rice and wheat. The research demonstrates the enhanced efficacy of residue application is significantly augmenting soil nutrient concentrations compared to standard tillage practices (P < 0.05). This was accomplished by an analysis of soil nutrient levels, namely nitrogen (N), phosphorus (P), potassium (K), and organic carbon (OC), at a depth of 0–15 cm. The implementation of natural farming, zero tillage, and reduced tillage practices resulted in decreases in rice grain yields of 34.0%, 16.1%, and 10.8%, respectively, as compared to conventional tillage methods. Similarly, the implementation of natural farming, zero tillage, and reduced tillage resulted in reductions in wheat grain yields of 59.4%, 10.9%, and 4.6% respectively, in comparison to conventional tillage practices. Conclusion Regarding the individual crop genotypes investigated, it was continuously observed that Him Palam Lal Dhan 1 and HPW 368 displayed considerably greater grain yields for both rice and wheat during the two-year experimental period. Furthermore, when considering different cultivation methods, conventional tillage emerged as the most effective approach for obtaining higher productivity in both rice and wheat. Additionally, Him Palam Lal Dhan 1 and HPW 368 exhibited superior performance in terms of various crucial yield components for rice (such as panicle density, grains per panicle, panicle weight, and test weight) and wheat (including effective tiller density, grains per spike, spike weight, and 1000-grain weight).
