“…Meanwhile, significant mean squares due to the interaction between genotypes and seasons were significant for all studied traits indicated that genotypes behaved differently in both summer growing seasons. These results are in line with those obtained by several investigators [6,8,9,10,11,24,25,26,27].…”

This work aimed at studying earliness, yield and photosynthetic parameters in some local and exotic rice resources. Twelve rice entries were used in the study including two from Bangladesh, one from Madagascar, three from Egypt, two from Korea and four from IRRI. These genotypes were evaluated during 2020 and 2021 seasons in RCBD using four replications at the Faculty of Agriculture, Moshtohor Experiment Station. Significant differences were found among rice entries for all studied traits in the two growing seasons. The genotype GZ 10686-1-2-2-1 was the earliest among all studied entries, while genotype PR 78 was the shortest among all entries. Entry IRRI 142 had the highest significant value for chlorophyll content comparing to Giza 179, panicle length was highest with the genotype SAIBORO 9361. The genotype Korea 27 expressed the best mean values for panicle weight, weight of 100 grain and grain yield plant -1 , while genotype IRRI 152 ranked the second best for grain yield plant -1 . Genotype GZ 10848-1-2-2-1 was the best for number of tillers plant -1 . Moreover, the genotype IRRI 152 exhibited the most desirable mean values for cuvette temp. and leaf diffusive, while genotype Korea 27 was the best for quantum sensor, stomatal conductance and Co2 assimilation rate in both seasons. For transpiration rate, the genotype AC 2882 expressed the best mean value, while Korea 47 gave the lowest value for this trait with significant difference from the variety Giza 179.

To clarify the agronomic and physiological characteristics of high‐yielding ratoon rice varieties, 14 rice varieties representing two types (high yield in ratoon crop [RH] and low yield in ratoon crop [RL]) were used as experimental materials. Compared with RL, the grain/leaf ratio of RH at the full heading stage in the main crop was lower. Also, the leaf area duration, net assimilation rate (NAR), crop growth rate (CGR), dry matter weight, photosynthetic rate of flag leaf, and root oxidation activity from the full heading to maturity stage in the main crop were higher. The leaf area index (LAI) and dry matter weight at maturity in the main crop were higher in RH than RL, whereas the rates of LAI attenuation, dry matter translocation and dry matter translocation efficiency (DMTE) from full heading to maturity, and harvest index (HI) in the main crop were relatively lower. The CGR, NAR, dry matter weight from full heading to maturity, and dry matter weight and root oxidation activity at maturity in the main crop were significantly and positively correlated with the yield of the ratoon crop. The rate of LAI attenuation and DMTE from full heading to maturity, grain/leaf ratio at full heading, and HI in the main crop were significantly and negatively correlated with the yield of the ratoon crop. Rational utilization of these agronomic and physiological characteristics would be helpful to screening and breeding high‐yielding rice varieties for ratoon production.

“…During in the Ninth Malaysia Plan period (2006–2010), the transformation of agriculture was focused on moving from traditional farming into modern and commercial agriculture, developing agriculture entrepreneurs, and familiarizing farmers and small landholders with all the new agronomic and modern farm management practices as contained in Good Agriculture Practice (GAP) (Guo et al 2020 ). The consolidation of small paddy farming was continued through the group farming concept in eight integrated paddy areas, and the ten metric tons per hectare (mt/ha) project was implemented throughout the period (Sarena et al 2019).…”

The COVID-19 pandemic resulted in more than 4.3 million confirmed cases and more than 2,90,000 deaths worldwide. It has also given rise to fears of an imminent economic crisis and recession. Social distance, self-isolation, and travel restrictions have led to a reduction in the workforce across all economical sectors and have led to a loss of many jobs. Schools have closed down, and the need for commodities and manufactured goods has decreased. On the other hand, the need for medical supplies has increased significantly. The food sector is also facing increased demand as a result of panic buying and storing food products. In response to this global outbreak, we summarize the socioeconomic effects of COVID-19 on the various aspects of the world economy. In Malaysia, the COVID-19 epidemic has checked the resilience of the agriculture sector. Especially the Malaysian paddy industry as country imports 30% of its overall consumption from different parts of the world. The real price of rice triplicating for the consumers, which was alarming for nations in this pandemic situation. The Government of Malaysia introduced the National Agrofood Policy 2011-2020 (NAP4) in 2010 as a guidance document for the implementation of agricultural sector development programs and projects in Malaysia. The NAP4 's 10-year term is to be finished by the end of 2020. Several sectors demonstrate substantial success after approximately 8 years of introduction, while the other classes often lag behind the goal and progress quite slowly. Agricultural sector performance is affected by many problems and challenges. In acknowledgment of the poor success of this field, the Ministry of Agriculture and Agri-Based Industry has launched new approaches, policies, and programs that can change the agricultural sector more rapidly. The new direction is aimed at ensuring national food security and boosting farm and revenues. The authorized government agency needs to revise the policy formulation where Malaysia needs to set stages to revolutionize and modernize the rice farming to address the problem faced by the paddy sector in this pandemic situation to adopt GF. In this study, the researcher focuses on the improvisation of the policy to increase the paddy production sustainably.
