“…Significant and higher number of effective tillers / hill was found with SWI, may be due to adequate space provided to the root to function at its maximum and uptake nutrients efficiently leading to increase in photosynthesis and effective tiller count. Similar results were reported by Mithilesh and Abraham [24]; Debbarma et al [25]. Further, significant and higher number of effective tillers / hill was with the application of Azospirillum due to phytohormones, antibacterial and antifungal compounds which stimulate root system and change in root morphology which in turn affect assimilates of nutrients thus influence the development of reproductive structures.…”

An experiment was carried out in the field during rabi season 2022-23 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.). The experiment was conducted to determine the response of wheat crop to different planting methods and biofertilizer application. There were nine treatments in the experiment, each replicated thrice and it was laid out in Randomized Block Design. The results showed that System of Wheat Intensification in combination with Azotobacter and Azospirillum recorded significant and higher plant height (101.93 cm), number of tillers / hill (12.91), plant dry weight (24.53 g), number of effective tillers / hill (9.78) and number of grains / spike (58.76). Whereas, Raised bed in combination with Azotobacter and Azospirillum significantly increased Leaf area index (3.66) and Crop growth rate (17.42 g/m2/day) compared to other treatments.

“…[ 34 ] reported that the leaf area index of wheat didn’t show any significant variation. However, they observed that PAR interception was statistically more in both sole wheat and wheat intercrop grown under 4 m × 8 m. While in the current study, square planting in wheat under SWI production system improves the effective tillers due to better utilization of the resources like moisture, nutrients, solar radiation, and leaf orientation, which increases photosynthesis and tiller expression [ 35 , 36 ]. Thus, square planting also helps to reduce the weeding time and encourages mechanical weeding resulting in lower weed flora and higher growth and yield attributes in wheat crop [ 37 , 38 ].…”

Intense cultivation with narrow row spacing in wheat, a common practice in the Indo-Gangetic plains of South Asia, renders the crop more susceptible to lodging during physiological maturity. This susceptibility, compounded by the use of traditional crop cultivars, has led to a substantial decline in overall crop productivity. In response to these challenges, a two-year field study on the system of wheat intensification (SWI) was conducted. The study involved three different cultivation methods in horizontal plots and four wheat genotypes in vertical plots, organized in a strip plot design. Our results exhibited that adoption of SWI at 20 cm × 20 cm resulted in significantly higher intercellular CO2 concentration (5.9–6.3%), transpiration rate (13.2–15.8%), stomatal conductance (55–59%), net photosynthetic rate (126–160%), and photosynthetically active radiation (PAR) interception (1.6–25.2%) over the existing conventional method (plant geometry 22.5 cm × continuous plant to plant spacing) of wheat cultivation. The lodging resistance capacity of both the lower and upper 3rd nodes was significantly higher in the SWI compared to other cultivation methods. Among different genotypes, HD 2967 demonstrated the highest recorded value for lodging resistance capacity, followed by HD 2851, HD 3086, and HD 2894. In addition, adoption of the SWI at 20 cm × 20 cm enhanced crop grain yield by 36.9–41.6%, and biological yield by 27.5–29.8%. Significantly higher soil dehydrogenase activity (12.06 μg TPF g-1 soil hr-1), arylsulfatase activity (82.8 μg p-nitro phenol g-1 soil hr-1), alkaline phosphatase activity (3.11 n moles ethylene g-1 soil hr-1), total polysaccharides, soil microbial biomass carbon, and soil chlorophyll content were also noted under SWI over conventional method of the production. Further, increased root volumes, surface root density and higher NPK uptake were recorded under SWI at 20×20 cm in comparison to rest of the treatments. Among the tested wheat genotypes, HD-2967 and HD-3086 had demonstrated notable increases in grain and biological yields, as well as improvements in the photosynthetically active radiation (PAR) and chlorophyll content. Therefore, adoption of SWI at 20 cm ×20 cm (square planting) with cultivars HD 2967 might be the best strategy for enhancing crop productivity and resource-use efficiency under the similar wheat growing conditions of India and similar agro-ecotypes of the globe.

“…organic sources of nutrients increased economic stability and returns, the cost of cultivation of wsheat crop recorded numerically higher (₹ 64,235.00/ha) value for the treatment of application of SWI + Vermicompost (4 t/ha) + Panchagavya 3% + Jeevamrut 500 l/ha and numerically minimum cost of cultivation was recorded with application of SWI + Poultry manure (5 t/ha) + Panchagavya 3% + Jeevamrut 500 l/ha (₹ 46,835.00/ha). Numerically highest gross return (₹1,44,000.00/ha), net return (₹ 95,940.00/ha), and B: C ratio (1.99) were obtained with the application of Row sowing + Poultry manure (5 t/ha) + Panchagavya 3% + Jeevamrut 500 l/ha among all the treatments [9][10][11].…”

The study was conducted at the certified organic experimental farm of SHUATS Model of Organic Farm (SMOF) at NAI, Prayagraj, in the winter rabi season of 2020-21. The primary objective was to scrutinize the nuanced impact of diverse sowing methods and organic manures on the yield attributes of wheat (Triticum aestivum L.). This comprehensive investigation consisted of nine treatments, each replicated three times and arranged in a randomized block design. Noteworthy findings emerged, revealing that Row sowing coupled with Poultry manure (5 t/ha), Panchagavya 3% FS, and Jeevamrut 500 l/ha FS resulted in the tallest plant height (78.30 cm). Moreover, the optimal combination of SWI with Poultry manure (5 t/ha), Panchagavya 3% FS, and Jeevamrut 500 l/ha FS exhibited the highest number of tillers per plant (10.53) and the maximum dry weight per plant (18.00 g/plant). Better yield performance, however, was achieved by Row sowing in conjunction with Poultry manure (5 t/ha), Panchagavya 3% FS, and Jeevamrut 500 l/ha FS, where it not only showcased the highest grain yield (3.16 t/ha) and straw yield (4.48 t/ha) but also demonstrated superiority in gross return (Rs. 1,44,000.00/ha), net returns (Rs. 95,940.00/ha), and an impressive benefit-cost ratio of 1.99. These outcomes underscore the paramount importance of precision in agricultural practices for achieving enhanced productivity and economic viability.
