“…The first two extracted PCs had eigenvalues higher than one and contributed 92.42% of the total diversity for combined data during normal and drought irrigation conditions. These findings were consistent with [37,39,71]. The PC1 accounted for 77.92% of the total variance of all analyzed variables, followed by PC2 and PC3.…”

The main constraint on rice cultivation in the Mediterranean area is the limited irrigation and its large water consumption. In addition, rice is very sensitive to drought conditions because of drought stress on morpho-physiological traits and yield reduction. The application of salicylic acid (SA) has been noticed to be very effective in alleviating the adverse effects of drought stress on rice. The current investigation was conducted as a split-split arrangement under a randomized complete block design with two lowland rice cultivars (Giza177 and Giza179) and SA as a foliar application at four concentrations (0, 400, 700, and 1000 µM) under normal and drought conditions. The results showed that plant growth, leaf photosynthetic pigments, yields, and the most studied traits were significantly affected by irrigation (I), cultivar (C), and SA concentration (p ≤ 0.05 or 0.01). The interaction effect of I × C × SA was only significant on the carotenoids content (p ≤ 0.05). The reduction in grain yield and most studied traits was more pronounced under drought conditions. The Giza179 proved to be a drought-tolerant cultivar under all SA concentrations under drought conditions, while Giza177 was a drought-sensitive cultivar. The application of 700 µM SA gave the best grain yield in both rice cultivars under drought conditions compared to other SA concentrations. Grain yield for normal irrigation (Yp) and drought stress (Ys) conditions were highly positively correlated with indices of the mean productivity (MP), geometric mean productivity (GMP), stress tolerance index (STI), yield index (YI), yield stability index (YSI), drought resistance index (DI), harmonic mean (HM), and golden mean (GOL). While they are highly negatively correlated with the indices of the stress susceptibility index (SSI), tolerance index (TOL), yield reduction ratio (YR), stress susceptibility percentage index (SSPI), and abiotic tolerance index (ATI). It could be concluded that SA, as a growth regulator, could be used to alleviate the harmful effect of inadequate water availability in soil on rice cultivars as well as to improve the growth, water productivity, and grain yield.

“…Thus, PC1 can be the basis in the weighting of the selection of variables such as genotypes and SA concentrations under both conditions. In other studies of rice, PC1 contributed the highest variance proportion with 51.10%, 57.65%, 58.83%, and 96.46% of the total variability [37][38][39]71], respectively.…”

“…This approach summarizes in detail all the important characteristics of plants in supporting their yield potential. It also becomes essential since an assessment based solely on the yield will confer a high error (Araya-Alman et al, 2019;Laraswati et al, 2021;Zafar et al, 2021). Grain yield is a quantitative and polygenic character which cannot be separated from environmental influences and interactions (Kassahun et al, 2013;Fellahi et al, 2018;Farid et al, 2020).…”

The evaluation of a cultivation technology would be more efficient when the technology assessment is based on various approaches like conventional morphological approaches, the use of drone’s normalized difference vegetation index (NDVI) imaging, and participatory plant breeding (PPB). The recent study aimed to assess the effectiveness of the combination of morphological approaches, drone imaging, and participatory plant breeding in selecting the best corn cultivation technology package. This research conducted in a randomized complete block design (RCBD) with one factor from March to December 2021 at the Village Taroang, Takalar Regency, South Sulawesi, Indonesia. The factor is 40 cultivation technology packages. The treatments were replicated three times, thus having 120 experimental units. For plant participation, the investigations were conducted with 56 farmers on their corn fields through quantitative surveys in the targeted area. For NDVI, the observation was recorded 70 days after planting using a DJI Inspire two unmanned aerial vehicles equipped with a multi-spectral camera. Based on the results of the study, the combined strategy of different approaches like morpho-physiological, drone’s NDVI, and participatory plant breeding is found effective in evaluating the corn production technology. The yield, plant height, percentage of net yield, and cob weight were good selection criteria for the morphology approach in evaluating corn cultivation. The NDVI could be recommended in helping the morphology evaluation and PPB, especially in a large-scale evaluation. Based on a combined assessment of the different approaches, the maize cultivar Pioneer-27 combined with ‘Legowo’ spacing technology, NPK fertilizer ratio of 200:100:50, KNO3 at the rate of 25 kg, and application of biofertilizer 'Eco farming' @ 5 cc L-1, was recommended as the best corn production technology package in the Village Taroang, Takalar Regency, South Sulawesi, Indonesia.

Image-based phenotyping in selecting drought- and salinity-tolerant rice lines is a potential approach to complement other selection criteria. This study aimed to determine tolerance response and selection criteria on drought and salinity stresses based on a morphological and image-based phenotyping character. The experiment, set up in a screen house of the Department of Agronomy, Faculty of Agriculture, Hasanuddin University, Indonesia, consisted of a nested randomized complete group design. The nested replication included stressed environments with two factors and three repetitions. The level of environmental stresses comprised the first factor, i.e., normal (without NaCl and PEG), salinity (60 and 120 mM NaCl), drought (10% and 20% PEG), and combination of drought-salinity (10% PEG + 60 mM NaCl). The second factor entailed the rice genotypes. Observations of the morphological and image-based phenotyping characters ensued. The results indicated that salinity stress had a wider diversity than drought stress, while the multiple stresses had a relatively stable variety compared with single stress. Morphological and image-based phenotyping character increased precision in assessing the tolerance or adaptability of rice to drought stress, salinity, and its combination. The morphological characters that can serve as rice selection criteria in a combination of drought-salinity stress included the shoot and root fresh weights and the root length. As for the image-based phenotyping character, the shoot phenotype width can serve as the selection criterion. Image-based phenotyping characters, especially the shoot phenotype area, were recommended as criteria for precise selection in assessing rice genotypes’ potential tolerance and adaptability to drought stress, salinity, and its combinations.
