Abstract
The current study, "Impact of nano-DAP on growth and development of cabbage," was carried out in 2021–2022 at the Department of Horticulture's Experimental Farm at A.A.U., Jorhat. RBD was used to set up the study. The treatments followed were T1 (Untreated control), T2 (100% RDF of N & K), T3 (100% RDF of 130:80:80 kg/ha), T4 (T2 + ST with nano-DAP @ 5 ml/ltr), T5 (T2 + ST@ 10 ml/ltr), T6 (T2 + 1 FS of nano-DAP @ 6 ml/ltr at 25-30 DAT), T7 (50 % P, 100% N & K + FS nano-DAP @ 2 ml/ltr at 25-30 DAT), T8 (25% P, 100% N & K + FS nano-DAP @ 4 ml/ltr), T9 (T2 + ST @ 5 ml/ ltr + FS nano-DAP @ 6 ml/ltr), T10 (25% P, 100% N & K + ST @ 5 ml/ ltr + FS nano-DAP @ 4 ml/ltr), T11 (50% P, 100% N & K + ST @ 5 ml/ ltr + FS nano-DAP @ 2 ml/ltr), T12 (25% P, 50% N & 100% K + ST @ 5 ml/ ltr + FS nano-DAP @ 4 ml/ltr) and T13 (50% P, 50% N & 100% K + ST @ 5 ml/ ltr + FS nano-DAP @ 2 ml/ltr).Investigation was done comparing the results of the nano-DAP treatments with the suggested fertilizer dosage. The results revealed that the maximum plant spread and number of non-wrapper leaves was observed in T3 (17.12 cm) and (7.67) at 30 DAT whereas in T3 (34.77 cm) and (16.83) at 60 DAT.The highest leaf area was recorded in T3 (107.56 sqcm) at 30 DAT and at 60 DAT (226.54 sqcm), although at 30 DAT, the maximum leaf fresh weight was recorded in T7 (4.40 g) although in T3 (12.46 g) at 60 DAT. The maximum number of days (88.30 days) to harvest was taken by T5. Thus, the investigation suggests that nano-DAP can reduce the amount of inorganic fertiliser applied while maintaining the potency of the crop.
