Zn and Cu accumulation in sugarcane crop as influenced by resource based organic farming

A field experiments was conducted at Organic Farm, Navsari Agricultural University, Navsari” during the years 2019-20 and 2020-21. The experiment was conducted using the RBD (factorial concept) with three replications. Two factors were tested in which one factor was spacing (S1: 90 cm and S2: 60 - 120 - 60 cm paired row with dhaincha green manuring) and another factor was compost levels (M1: NADEP compost @ 100 % RDN, M2: NADEP compost @ 75 % RDN, M3: NADEP compost @ 50 % RDN and M4: NADEP compost @ 25 % RDN + sugarcane trash @10 t/ha + jeevamrut @ 2000 l/ha.). Zn and Cu content of cane and trash, were affected significantly by the compost treatments in pooled analysis. Significantly higher content of these nutrients was observed in treatment M1 as compared to remaining treatments.
