Abstract
The experiment entitled “Effect of different implements for improving the productivity and quality of Sugarcane ratoons (Sacharum officinarum L.)” was conducted during Eksali, 2014 on red sandy loam soils of Agricultural Research Station, Basanthpur, Medak Dist. The treatment includes conventional and mechanical management practices of sugarcane ratoon laid in four replications.
The field performance of different ratoon implements (Disc off barrier, Ratoon manager, Mini rotoweeder, Ridger, Mini plough, Conventional plough and Harvester) was evaluated in three village viz., Basanthpur, Kalbemal and Madgi of Medak District. Among the three villages, Basanthpur village had recorded highest values for all the ratoon implements. The effective field capacity of the disc off barrier, Ratoon manager, Mini rotoweeder, Ridger, Mini plough, Conventional plough and Harvester in Basanthpur are 0.18 ha h-1,0.45ha h-1, 0.31 ha h-1, 0.04ha h-1,0.088 ha h-1, 0.02 ha h-1, 0.34 ha h-1 respectively , with a fuel consumption of 0.013m3ha-1,0.0152 m3ha-1, 0.018 m3ha-1,0.015 m3ha-1, 0.0125 m3ha-1 , 00 m3ha-1,0.020 m3ha-1respectively.
Biometric observations of growth parameters, yield attributes and yield were recorded and analysed. Accordingly, the effect of different implements on soil parameters and root growth was also recorded. Significantly highest and at par tiller number at 75 and 120 DAP, plant heights, millable canes, single cane weight, cane yield, sugar yield and cane girth(96.750, 162.91, 333.60, 102.280, 1.39, 148.46, 19.80,

2.97) were recorded in T6 (Improved method running with stubble shaver + disc off barrier + inter cultivation by tractor + mechanical harvesting) and T5(83.15, 152.07, 319.04, 99.643,1.36, 136.82,18.54, 2.88) (Improved method running with stubble shaver + intercultivation by tractor + manual harvesting) treatments. While, significantly lowest and at par crop parameters were noted with T1 (Conventional with manual shaving + inter cultivation by draught animal + manual harvesting) and T2 (Conventional with manual shaving + inter cultivation by tractor + manual harvesting) treatments.
Higher root mass of 205.69 – 211.36 g was recorded in T4, T5 and T6 treatments which involve the use of stubble shaver, disc off barrower and a ratoon manager. On the other side, the conventional treatments in which shaving was done manually has registered a root mass of 171.65 – 188.97 g. Maximum decrease of 1.38 gm cm-3 in bulk densitywas observed in T6 while the minimum was observed in T1. On the other hand, the pore space was maximum (38.85%) in T6 and minimum in T1 (31.62%).
The crop fetched maximum gross and net returns of Rs.385996 and 263108 ha-1 respectively due to T6. Whereas, the minimum gross returns of Rs. 275600 and 168820ha-1, respectively were obtained due to T1. Therefore, ratoon management with stubble shaving, disc off barring followed by intercultivation by tractor and mechanical harvesting was foundeconomical with a benefit cost ratio of 2.14 followed by T5 with a benefit cost ratio of 2.08.
