“…Among the varieties tested, highest plant height at all the growth stages was recorded in Inglongkiri which might be due to the genetic character of the variety (Table 1) as plant height depends on genetic makeup of a plant and environmental conditions. A similar findings was reported by Asif et al (2014), Ramachandra et al (2015) and Kannan et al (2015). Leaf Area Index was recorded highest in 1 st April sown crop and sowing date significantly affected this physiological parameter.…”

“…L) Varieties in Assam was followed by variety Inglongkiri and this is probably due to more effective tillers/m 2 and higher length of panicle exhibited by CR-Dhan 203 over rest of the varieties and also might be due to variation in genetical character of the variety. The significant differences in yield attributes among the rice varieties have also been reported by Brar and Bhullar (2013), Dawadi and Chaudhary (2013), Ramachandra et al (2015), Kumar et al (2015) and Tiwari (2015). The crop sown on 1 st April produced higher values in all the attributes and yield followed by 16 th March sown crop.…”

Background: Rice (Oryza sativa L.) is the major cereal crop grown in India. Rice plays a pivotal role in the socio-cultural life of the people of Assam. The main objective of this study to investigate the influence micro climatic indices in relation to crop growth and yield of upland rice varieties with different dates of sowing in Assam. Methods: A field experiment was carried out at Instructional cum Research Farm, Assam Agricultural University, Jorhat during autumn season of 2017. The experiment consisted of four micro-climatic regimes (M) along with four different rice varieties (V). Result: The results of the experiment revealed that micro climatic indices viz., canopy temperature, growing degree days, soil moisture content, soil temperature, light intensity, depth of ground water table associated with 1st April sown crop recorded positive effect on growth and yield parameters in terms of plant height, leaf area index, number of filled grains per panicle, test weight, harvest index and grain yield (3004 kg/ha), followed by the micro-climate associated with 16th March sown crop. Among the varieties evaluated, CR-Dhan 203 recorded the highest grain yield of 2860 kg/ha and was significantly superior to that of other varieties except Inglongkiri.

“…The LSD test revealed that the variations in grain yield among planting dates and genotypes were statistically significant at a level of (P<0.05). These studies, along with the data presented here, highlight the importance of selecting an appropriate sowing date for rice crops to maximize their potential performance and yield (Wang et al 2021& Ramachandra et al, 2015.…”

Rice (Oryza sativa L.) is a vital food crop that holds a significant position in the world's economy. It ranks third globally in terms of production, following wheat and maize. Moreover, rice serves as the staple food crop for approximately two-thirds of the world's population. The planting date has a significant impact on rice productivity. When rice is sown under optimal conditions, including favorable air and soil temperatures and adequate soil moisture, the crop's performance shows a notable improvement. Nonetheless, planting rice too early can expose the crop to cold temperatures, which may result in poor germination, low seedling vigor, and seedling mortality. Conversely, planting too late can lead to reduced yields and grain quality since the critical reproductive phase coincides with the peak of summer heat, negatively affecting rice grain yield and quality. During the Khaif season of 2022, the field experiment was conducted at the Rice Research Center (RRC) Dokri. The experiment was laid out in split plot design containing three sowing dates’ viz. 30thJune, 15thJuly and 30thJuly in main plots and four rice genotypes viz. NUYT-M-11, NUYT-M-8, NUYT-M-10 and Latify (check) as sub plot treatments. Nevertheless, rice crops sown on June 30th demonstrated markedly superior performance compared to other sowing dates. These crops exhibited a plant height of 97.27 cm, 19.18 tillers per plant, a panicle length of 20.11 cm, a seed index of 29.82 g, a biological yield of 8964 kg/ha, a grain yield of 5330 kg/ha, and a harvest index of 84.11%. The interaction between genotypes and sowing dates significantly influenced the observed plant height, tillers per plant, panicle length, seed index, biological yield, grain yield, and harvest index. Among the genotypes, NUYT-M-11 sown on June 30th displayed the highest values for these parameters.

Shortage of water in rice cultivation is major problem in India. To safeguard and sustain food security in India, it is quite important to increase the productivity of rice under limited water resources. To investigate the performance of rice cultivars under the best method of irrigation and system of cultivation in new condition an experiment was conducted to study the "productivity and water use efficiency of rice (Oryza sativa L.) cultivars under different irrigation regimes and systems of cultivation" on clay loam soils of Indian Institute of Rice Research (IIRR), Rajendranagar, Hyderabad, Telangana during the kharif seasons of 2017 and 2018. The treatment comprised of two irrigation regimes viz., AWD and saturation as main plot treatments, three establishment methods viz., system of rice intensification, drum seeding and TP as subplot treatments and four cultivars namely DRR Dhan 42, DRR Dhan 43, MTU-1010 and NLR-34449 as sub-sub plot treatments summing up to 24 treatment combinations laid out in split-split plot design with three replications. Among the irrigation regimes, AWD irrigation practice recorded higher grain yield (5755, 5952 and 5854 kg ha-1 in 2017, 2018 and pooled means, respectively) than saturation. Among the different systems of cultivation, the SRI recorded significantly higher grain yield (5953, 6129 and 6041 kg ha-1 during 2017, 2018 and in pooled means, respectively) over the TP method. Among the different rice cultivars, DRR Dhan 43 registered remarkably higher grain yield than other cultivars during 2017 and 2018.
