RESUMEN
India is called a home for spices and also involved in the export. Chilli is an indispensable spice, essentially used in every Indian cuisine due to its pungency, taste, appealing odour and flavour. Quality seed is a key component for the successful agriculture, where the main objective is each seed should germinate and produce a vigorous seedling which ensures higher seed yield, productivity and also better storability to achieve good yield in the coming season. To achieve all the above said traits, the seed technologists have developed seed enhancement techniques. Seed enhancement techniques are post-harvest treatment of seeds to enhance the seed germination and seedling growth by facilitating the delivery of seeds with other materials at sowing time. This enhancement technique includes hydration treatments like seed priming and seed encapsulation like seed pelleting, which impacts significantly on seedling emergence and establishment. In this experiment study was conducted different priming treatments, seeds primed with KNO3 @ 1%, 2% and 3% and seeds primed with GA3 @ 50 ppm, 100 ppm and 150 ppm, the seeds treated with KNO3 @ 1% showed highest germination percentage, root, shoot, seedling length, seedling dry weight and seedling vigour index I and II which was followed by GA3 @ 50 ppm. Acknowledge of proper priming techniques in order to improve the germination in the seeds.
RESUMEN
The relevance of Water in human life and agro-ecosystems has been extensively illustrated for decades around the globe. Despite the reality that the earth is mostly surrounded by water, its utility has been limited to domestic consumption and agricultural purposes. Thus, tweaking water usage in agricultural systems has been a tricky problem in order to meet the requirements of the growing population and to obtain more crop yield per drop of water in agriculture. In this review, an attempt has been made to revisit the methods available to improve water use efficiency in agriculture.
RESUMEN
The experiment was conducted to study the comparative performance and blast disease screening 80 diverse rice cultivars including land races, obsolete varieties, modern cultivars and released varieties, local prevailing cultivars and advanced breeding/varietal lines as AICRIP testing trials for two successive seasons during Kharif-2021 and Kharif-2022 at AHRS Ponnampet, Karnataka- India, The results from ANOVA revealed that, MSS due to genotypes, were significant (p<0.01 and p<0.05) for all the yield traits studied. GYKH was varied from 270.65-6039.89, while 940.17-6039.88 with mean grain yield Kg/ha of 3596.01 and 3483.92 kg/ha during Kh-21 and Kh-22. High GCV and PCV with high heritability coupled with high GAM were observed for GYKH, while the remaining traits revealed low to medium GCV and PCV, heritability coupled with low to medium GAM. Correlation analysis revealed that significant and positive association was observed for PH, DFF, PL and GYKH. PCAs revealed that PC1, PC2 and PC3 showed 32.45%, 29.66% and 14.83% of contribution with 76.94% of total variation during Kharif-21 and 33.20%, 29.67% and 14.33% of contribution with 77.20% of variation for the studied traits during Kharif-22 respectively. Field screening of leaf and neck blast under natural hot spot area among 80 diverse genotypes resulted in identification of resistant sources as KPR-1, KPR-2, KHP-5, Mud-1014, IET-28515 and Kajajaya with promising yield performances.
