A research on determınıng the effect of dıfferent ırrıgatıon methods ın reduced tıllage systems on some morphologıcal characterıstıcs and yıeld of sunflower

This comprehensive study explores the synergies between various irrigation systems and two conservation tillage strategies, namely decreased tillage, in the context of modern agriculture. The study focuses at the complex links between irrigation practises and crop results in order to improve farming sustainability. The approaches include a full field experiment combining a variety of irrigation technologies such as drip irrigation and sprinkler systems. This study looked into the effectiveness of drip irrigation and sprinkler irrigation in decreasing soil cultivation for a second crop of sunflowers after oat harvest. Statistical analysis and experimental design were used to determine the best drip and sprinkler systems. The ANOVA and Duncan's Multiple Range Test were used to compare the results. We also investigated and compared the efficacy of various irrigation schemes for field bud emergence in second-crop sunflower agriculture. The sprinkler irrigation system had the highest occurrence rate of 89.05%, followed by the drip irrigation system, which had an occurrence rate of 88.05%. Due to the seeds receiving moisture, the drip irrigation technique scored second in terms of germination rate when compared to the old method. No-till and low-tillage crops showed increased water content and emergence rates. There were statistically significant differences between the techniques in terms of plant height, stem diameter, head diameter, and productivity. The rainfall irrigation technique produced the tallest plants, whereas the drip irrigation system produced the shortest. The conventional technique had the largest head diameter, whereas the sprinkler irrigation treatment had the lowest. The difference in average sunflower output between approaches was significant, with spray irrigation generating the most (347.77 mg ha-1), drip irrigation producing the most (346.90 mg ha-1), and no irrigation producing the least (291.63 mg ha-1).
