Abstract/ Executive Summary:

There was significant difference in tiller, millable cane and pol % cane. In case of tiller production, the highest tillers (166.30 × 103 ha-1) were found in T3 (166.30 × 103 ha-1) treatment ( T1 + Fungicide spraying) followed by treatment T8, T7, T6 and T3 while the lowest was in treatment T1 (129.00 × 103 ha-1). The maximum number of millable canes were observed in treatment T8 (143.90 × 103 ha-1) followed by treatment T7, T6, T5, T4 and T3 and the lowest was in T1 (121.40 × 103 ha-1) treatment. The highest cane yield (66.88 t ha-1) was obtained from T8 (T1 + Trash mulching + Fungicide spray + Urea spraying) treatment and the lowest yield (59.75 t ha-1) was recorded from T1 treatment. The highest pol % cane (10.64 %) was found T2 treatment (T1 + Trash mulching) and the lowest (8.06 %) was recorded from T1 treatment. The overall result suggested that existing ratooning practice with trash mulching + fungicide spray + urea spraying was performed better and these technologies might be used for large scale adoption in farmers field.

Objectives:

i) To increase ratoon cane yield by trash management ii) Enhancing the germination of ratoon cane through fungicide and urea spraying iii) To increase sugarcane production as well as economic benefit.

Methodology:

Treatments: T1 : Existing ratooning practice (control) T2 : T1 + Trash mulching T3 : T1 + Fungicide spraying T4 : T1 + Urea spraying T5 : T1 + Trash mulching + Fungicide spraying T6 : T1 + Trash mulching + Urea spraying T7 : T1 + Fungicide spraying + Urea spraying T8 : T1 + Trash mulching + Fungicide spray + Urea spraying Plot size : 8m x 8m Replications : 3 Design : RCB Cane Variety : Isd 34 Gross area : 0.20 ha Fertilizer application : As per recommendation Irrigation and cultural practices : As and when required Data to be collected: 1. Germination/Establishment ( %) of stubble. 2. Tiller population at 120, 150 and 180 DAT. 3. Millable cane stalks at harvest. 4. Unit stalk weight, height, girth, internodes 5. Cane yield at harvest. 6. Pol % cane at harvest
