Abstract: Field experiments were conducted during rabi season of 2017-2018 and 2018-2019 at College farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari to study the “Effects of tillage practices and fertility levels on growth, yield and quality of sugarcane (Saccharum officinarum L.) under South Gujarat conditions”. Total sixteen treatment combinations consisting of four treatment of tillage practices T1: Cultivation with cultivator, T2: Sub soiling (45 cm depth & at 2 m distance in square) + Cultivation with cultivator, T3: Deep ploughing (22.5) + Cultivation with cultivator T4: Rotavator + Cultivation with cultivator and four treatment of fertilizer levels F1: 75% RDN (187.5 N kg/ha), F2: 100% RDN (250 N kg/ha), F3: 125% RDN (312.5 N kg/ha), F4: 150% RDN (375 N kg/ha) was laid out in Split Plot Design with three replications. The sugarcane cultivar used in the study was Co N 13073.
Germination of sugar cane setts at 30 & 45 DAP and girth of millable cane at harvest were not differed significantly during both the years due to different tillage practices. While, plant height, number of tillers, number of internode, single cane weight, millable cane length and millable canes per hectare were found significantly higher under treatment the T2 (Sub soiling 45 cm depth & at 2 m distance in square + Cultivation with cultivator). While, treatment having cultivation with cultivator (T1) recorded significantly lower growth parameters and yield attributes than rest of the treatments during both the years as well as in pooled result.
The results of present investigation further revealed that growth and yield attributing characters, viz germination of sugar cane setts and girth of millable cane at harvest were not differs significantly during both the years due to different fertilizer levels. While, plant height, number of tillers, number of internode, single cane weight, millable cane length, millable canes per hectare, cane yield were found significantly higher under the treatment 125% RDN (F3) followed by the fertility level 150% RDN (F4). However, treatment 75% RDN (F1) recorded lowest value of all growth parameters and yield attributes during both the years as well as in pooled analysis.
Treatment T2 (Sub soiling 45 cm depth & at 2 m distance in square + Cultivation with cultivator) registered maximum gross realization (₹ 4,87,243/ha) and net realization (₹ 3,79,832/ha) with B:C ratio of 3.54. While, the lowest gross realization (₹ 3,73,651/ha) and net realization (₹ 2,70,240/ha) with B: C ratio of 2.61 was obtained under T1 (Cultivation with cultivator) treatment. The highest gross realization (₹ 4,72,537/ha), net-realization (₹ 3,69,535/ha) and B:C ratio (3.52) were obtained with the treatment F3 (125% RDN). While, the lowest gross realization (₹ 3,78,049/ha), net realization (₹ 2,70,755/ha) and B:C ratio (2.62) was obtained under the treatment F1 (75% RDN).
