Iron and Mn accumulation in sugarcane crop as influenced by resource based organic farming

A field trial was conducted at Organic Farm, Navsari Agricultural University, Navsari” during the years 2019-20 and 2020-21.  The objectives of study were (i) To find out the effect of available organic resource-based treatments on growth, yield and quality of sugarcane, (ii) To study the effect of available organic resource-based treatments on soil properties and (iii) To work out the economics. 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.). Among the Fe, Mn, content of cane and trash, Fe in 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.
