“…In general, protein content was negatively correlated with eating quality because rice with a higher protein content had lower adhesiveness, glossiness, taste, and stickiness when cooked than rice with a lower protein content [43][44][45][46]. The results of the study indicate that the protein content of rice can be significantly influenced by the transplanting date, even when the same level of fertilizer is applied.…”

This study aimed to investigate how transplanting date affects the agronomic and grain quality traits of two early-maturing rice varieties. The experiment was conducted in the rice research field of Chungnam Agricultural Research and Extension Services in South Korea and rice materials were transplanted at intervals of approximately 15 days from 16 April to 16 July in 2019 and 2020. Results showed that agronomic and grain quality traits varied according to the transplanting date and earlier transplanting resulted in a longer period of days from transplanting to heading (DTH). The spikelet number m−2 was highly correlated with the milled rice yield (r = 0.963 ** for Jinbuol, r = 0.909 ** for Yeoreumi) and it significantly decreased as the transplanting date was delayed, which was leading to lower yield. The mean temperature during the grain filling stage had a negative correlation with head rice rate (r2 = 0.825 ** for Jinbuol, r2 = 0.803 ** for Yeoreumi) and the number of days from transplanting to heading showed negative correlation with protein content (r2 = 0.777 ** for Jinbuol, r2 = 0.833 ** for Yeoreumi). Therefore, increasing the number of days from transplanting to heading date can lead to higher milled rice yield and lower protein content and avoiding heading dates on 17 July can improve the appearance traits. As a result, it is suggested that early transplanting is advantageous to increase the milled rice yield and grain quality of early-maturing rice.

Implementing a cropping intensity program with rice cultivation four times a year (CI 400) can be achieved using early maturing varieties of rice. However, this development needs to pay attention to the adaptability of the varieties planted to ensure successful implementation. The adaptability approach is a combination of assessing stability and productivity potential. This concept has been developed and applied in several studies, including research on rice. However, this approach is considered less comprehensive because it is non-parametric and only focuses on one stability analysis. Therefore, a systematic integration of various stability analyses, including index methods, is needed to comprehensively assess adaptability, particularly for early-maturing rice in South Sulawesi. This region is characterized by a dynamic climate zone and is one of the top four highest rice producers in Indonesia. Meanwhile, this study aims to develop a comprehensive adaptability index and select the best early-maturing rice varieties, especially in South Sulawesi. The investigation was conducted in Bone, Soppeng, and Gowa over two seasons using a nested randomized complete block design, with organized replications in each environment (location-season). Additionally, there was a significant focus on the application of five early-maturing and two check rice varieties, with each factor repeated three times at each location, totaling 126 experimental units. The results showed that the adaptability index, by combining stability rank accumulation with yield min max standardization, was effective at assessing the yield potential and stability of early-maturing rice varieties in supporting CI 400. Inpari 13 had the best index value at 0.55, followed by Cakrabuana at 0.31; hence both were recommended as adaptive early-maturing rice varieties, especially in South Sulawesi.
