“…Under the conventional system, cultural practices of transplanting of older seedlings at three to four seedlings/hill, continuous flooding of the field throughout crop would have resulted in poor root growth with quicker root degeneration (Chakraborty et al, 2017). Nirmala et al (2021) reported that conventional method of rice production yield was reduced up to 55% compared to SRI methods. Thus, adaptation of rice production technique like SRI, DSR, and TPR (mechanical) with AWD in rice ecology may enhance overall productivity along with resilience to climate change (Lal et al, 2020;.…”

IntroductionConventional rice production techniques are less economical and more vulnerable to sustainable utilization of farm resources as well as significantly contributed GHGs to atmosphere.MethodsIn order to assess the best rice production system for coastal areas, six rice production techniques were evaluated, including SRI-AWD (system of rice intensification with alternate wetting and drying (AWD)), DSR-CF (direct seeded rice with continuous flooding (CF)), DSR-AWD (direct seeded rice with AWD), TPR-CF (transplanted rice with CF), TPR-AWD (transplanted rice with AWD), and FPR-CF (farmer practice with CF). The performance of these technologies was assessed using indicators such as rice productivity, energy balance, GWP (global warming potential), soil health indicators, and profitability. Finally, using these indicators, a climate smartness index (CSI) was calculated.Results and discussionRice grown with SRI-AWD method had 54.8 % higher CSI over FPR-CF, and also give 24.5 to 28.3% higher CSI for DSR and TPR as well. There evaluations based on the climate smartness index can provide cleaner and more sustainable rice production and can be used as guiding principle for policy makers.

“…SRI practices create more favorable conditions for plant growth by (a) minimizing inter-plant competition, with seedlings planted singly, not in clumps, and with wide spacing between them, (b) starting with very young seedlings if establishing the crop by transplanting, taking care to minimize trauma to plant roots, while (c) creating healthier soil conditions, by (i) managing water so as to avoid anoxic soil conditions and also water-stress, (ii) active surface soil aeration during mechanical weeding, and (iii) increasing organic soil amendments (Thakur and Uphoff, 2017;Thakur et al, 2020;Mishra et al, 2021). Grain yields from SRI plants are generally 25-100% higher than from non-SRI rice crops (Nirmala et al, 2021;Shah et al, 2021;Thakur et al, 2022). In a number of ways, rice plants grown with SRI methods show superior morphological and physiological characteristics (Thakur et al, 2011;Thakur et al, 2023).…”

The system of rice intensification (SRI) is an extensively-researched and increasingly widely-utilized methodology for alleviating current constraints on rice production. Many studies have shown physiological and morphological improvements in rice plants induced by SRI management practices to be very similar to those that are associated with the presence of beneficial microbial endophytes in or around rice plants, especially their roots. With SRI methods, grain yields are increased by 25-100% compared to conventional methods, and the resulting plant phenotypes are better able to cope with biotic and abiotic stresses. SRI management practices have been shown to be associated with significant increases in the populations of certain microorganisms known to enhance soil health and plant growth, e.g., Azospirillum, Trichoderma, Glomus, and Pseudomonas. This article evaluates the effects of applying Trichoderma as a model microbe for assessing microbial growth-promotion, biological control activity, and modulation of gene expression under the conditions created by SRI practices. Information about the molecular changes and interactions associated with certain effects of SRI management suggests that these practices are enhancing rice plants’ expression of their genetic potentials. More systematic studies that assess the effects of SRI methods respectively and collectively, compared with standard rice production methods, are needed to develop a more encompassing understanding of how SRI modifications of crops’ growing environment elicit and contribute to more robust and more productive phenotypes of rice.

“…Its pivotal role in ensuring national food security cannot be overstated. However, as we look towards the future, the imperative to further augment rice production becomes apparent, driven by the escalating food demands in the face of fierce competition for limited agroresources, especially productive land and water [2].…”

The way agricultural commodities' prices behave indicates how prices occasionally fluctuate between markets [1]. Comprehensive analysis provides valuable insights into the dynamics of paddy prices in Gujarat, emphasizing the importance of considering both short-term fluctuations and long-term trends. The findings contribute to a better understanding of market behaviour, aiding stakeholders in informed decision-making within the agricultural sector. In order to provide farmers with the knowledge of how much prices fluctuate over time in commodity markets and so increase their revenue, a ten-year study on the price behaviour of paddy was conducted inside the borders of the state of Gujarat (2009-2019). In order to gather statistics, three paddy markets in the state of Gujarat were specifically chosen based on the paddy arrivals that were highest. The trend diagram of the wholesale prices' yearly index number showed constant price fluctuations across the study period. Cuddy Dell Valle Index (CDI) was calculated to measure the instability in yearly and monthly prices. Based on the investigation, it was determined that paddy displayed a poor stability index within their respective marketplaces. The trend in paddy prices was measured using the linear and quadratic models. For paddy markets, the coefficient of multiple determination (R2) was greater than 70%. Thus, it can be said that a significant portion of the changes in paddy prices over the chosen study period can be attributed to the linear model. In keeping with the quadratic trend, the markets for paddy, or Ahmedabad and Gandhinagar, also showed a positive coefficient of the quadratic term, or T2. Comparing the quadratic and linear model for the markets of paddy the quadratic model performed better in Gandhinagar than the linear model did in Ahmedabad and Surat. Compound rate of increase in annual prices were analysed by exponential model. The rates of growth in the prices of Paddy in Ahmedabad, Surat, and Gandhinagar were 5.80 percent, 5.84 percent, and 4.68 percent, respectively. To separate seasonal variation from the original composite data, a multiplicative model was applied. To arrive at the twelve-month total of 1200 points, these ratios were averaged for each of the twelve months for the whole period. The Ahmedabad market's paddy produced the highest coefficient of seasonal variation (25.84 percent).
