“…This could be due to increased sunlight availability following the in-situ incorporation of sunnhemp at 45 DAP, as well as possibly increased nutrient availability. This result is consistent with Udayakumar (2003) findings. Planting at 180 cm in single row planting resulted in reduced tillers in all treatment combinations.…”

“…This finding is in conformity with the findings of Guru (1997). Similar findings of increased number of millable canes due to green manuring were also reported by Jayapaulet al (2000), Udayakumar (2003), Roodagi (2001), Manimaran et al(2009) and Ombase et al (2018). Among the sixteen treatment combinations, planting sugarcane at 150 cm in double rows and intercropping with sunnhemp (M2S4) produced the highest number of millable canes (110.90×10 3 and 93.13×10 3 ha -1 during 2016-17 and 2017-18, respectively).…”

Field experiments were carried out at the Sirugamani, Sugarcane Research Station of Tamil Nadu Agricultural University India in 2016-17 and 2017-18. The studies were designed to optimize crop geometry and identify a suitable intercrop for a novel planting technique of the sustainable sugarcane initiative. Sixteen treatment combinations (intercrops and crop geometries) were replicated three times in a strip plot design. Four crop geometries such as 150 x 60 cm single row planting, 150 x 60 cm double row planting, 180 x 60 cm single row planting, and 180 x 60 cm double row planting were assigned to the main plot. The subplot, on the other hand was earmarked for sugarcane-based intercropping, which included sole sugarcane, sugarcane + greengram, sugarcane +blackgram and sugarcane +sunnhemp. The intercrops were grown in an additive series, with three rows of sugarcane planted at 150 cm and four rows planted at 180 cm row spacing. The crop received an average of 730.3 mm of rain over the trial period. The soil at the research site was a well-drained clay loam with low, moderate, and high nitrogen, phosphorus, and potassium availability, respectively. A surface drip fertigation system was used to schedule the fertilizers and irrigation to the crops. By observing cane yield and yield-attributing characteristics at harvest, the impact of crop geometry and sugarcane intercropping in the sustainable sugarcane initiative method was investigated. In comparison to the majority of sugarcane-based intercropping, sugarcane+sunnhemp intercropping produced significantly more tillers at 120 days after planting i.e.150.60 × 10 3 and 88.88 × 10 3 tillers ha -1 , respectively, in 2016-17 and 2017-18. Furthermore, growing sugarcane+sunnhemp intercropping yielded more millable canes (89.90× 10 3 and 1.43× 10 3 ) and cane equivalent yield (138.92 and 139.04 t ha -1 ) in 2016-17 and 2017-18. The 150×60 cm double row planting of sugarcane was found to be the best among the four crop geometries, yielding the highest cane equivalent yields of 132.85 and 152.56 tha -1 during plant I and plant II crops.
