The Role of Levels and Times of Application of Super Micro Plus Nanofertilizer on some Growth Characteristics and Stems Yield of Sugarcane Saccharum officinarum L.

Abstract A field experiment was carried out in one of the agricultural fields Muqdadiya region during season 2022-2023 to study role spraying with nanofertilizer called Super Micro Plus at levels (0, 1, 2 and 3) g/L as a first factor times (the beginning tillering stage, elongation maturity stage) second some growth characteristics stems yield sugarcane, variety Cp 89. The according completely randomized blocks design three replications, data were analyzed statistically, results showed following: 1. use level resulted significant increase number total stems, stem height, diameter, leaf area green leaves, they reached 57.8, 160.7 cm, 30.7 mm, 1126.1 cm /plant 10.1 leaf/plant respectively. It also caused an mean yield, reaching 61.5 tons/ha, 56.1 %. 2. stage 61.6, 31.8 1127.9 9.9 respectively, decrease it 155 cm. 53.6 tons/ha. 3. Spraying plants g / L highest 69.4, 33.1 1187.5 11.7 leaves plant And 153 achieved 66 tons ha, 67.5
