“…The probable reason for minimal 1000 grain weight (g) is shortening of grain filling duration which reduced seed weight. Results supporting our findings were also quoted by Alam et al (2012) and Hussain et al (2013), who also suggested a significant performance of different transplantation date on 1000-grain weight (g) in rice.…”

O n universal based, rice crop is planted on region of 153 million hectares among whole production of 672 million tons. China is the biggest grower of rice, the total production is 196 million tons and after that India is the 2nd biggest rice producer in the world within 133 million tons, while Indonesia produced sixty four million tons, Bangladesh forty seven million tons, Vietnam thirty eight million tons & Myanmar thirty two million tons. However, in Pakistan rice is grown on 2.3 million hectares area by means of total production of rice in Pakistan is 7.2 million tons (FAOSTAT, 2017). Pakistan is among from those countries which are producing and exporting very good quality fine rice. In our country rice Abstract | Climate change has emerged as the most prominent global environmental issues and there is a need to evaluate its impact on agriculture. It is need of the hour to determine suitable transplanting time for rice in this changing climate scenario to have better yield. The experiment was conducted to study the response of transplanting dates and seedlings densities on fine rice variety "Super Basmati" at Agronomic Research Farm, Faculty of Agriculture, Gomal University, Dera Ismail Khan during 2017. The experiment was laid out in a Randomized complete block design with three replications, because of two factors and four levels of each; split plot design was carried out. Main plots were assigned seedlings hill -1 viz. 1, 2, 3 and 4 seedlings, while sub-plots were of four different transplanting dates i.e. 18 th July, 25 th July, 1st August and 8 th August. Data was recorded on flag leaf area (cm 2 ), chlorophyll content (μ g cm -2 ), plant height (cm), number of fertile tillers hill -1 , number of unfertile tillers hill -1 , panicle length (cm), spikelet fertility (%), number of grains panicle -1 , 1000-grain weight(g), biological yield (kg ha -1 ), grain yield (kg ha -1 ), benefit cost ratio (BCR) and Harvest index (%). Seedling density showed significant differences for traits such as unfertile tiller hill -1 , while transplanting dates also indicated significant differences for biological yield, grain yield, plant height, spikelet fertility (%), 1000-grain yield and number of unfertile tiller per plant. Seedling densities and transplanting dates interaction also showed significant differences for various parameters under study. Data revealed that 3 seedlings hill -1 transplanted on 18 th July gave maximum grain yield (4700 kg ha -1 ) and benefit cost ratio (2.70). Therefore, fine rice variety "Super Basmati" is recommended for transplanting on 18 th July by using 3 seedling hill -1 under the environmental conditions of Dera Ismail khan.

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.
