RESEARCH FINDINGS

Varietal evaluation and the All India Co-ordinated Research Project.

Objective:

To study the performance of early and midlate maturing varieties.

Inference:

Fourteen varietal trials comprising of six initial varietal trials and eight advanced varietal trials involving 86 entries (38 early and 48 mid-late) were conducted. The advanced varietal trials were conducted for two plant and one ratoon seasons.

In the early duration segment, entries such as Co 09004 and 10027 and in the mid-late duration segment, CoM 11085 performed better than the standards CoC 671 and Co 86032.

Response of sugarcane varieties to planting dates and stages of harvest..

Objective:

To study the performance of sugarcane varieties to dates of planting and stages of harvest.

Inference:

Under the agro climatic conditions of Northern Karnataka, CoC 671 and Co 86032 continued to perform better when planted from August to January. 

While, for February planting, the new variety Co 07015 was found best. Harvesting at 14 months gave the best cane and sugar yield.

Performance of new sugarcane varieties for commercial cultivation..

Objective:

To study the performance of new clones for yield and quality parameters.

Inference:

In the first plant crop, Co 14012 recorded highest cane yield and CCS yield followed by Co 14024. 

Co 2012-293 and Co 11015 recorded higher sucrose %. The study is in progress.

Evaluation of energy canes..

Objective:

To study the performance of energy canes.

Inference:

In the second plant crop, SBIEC 14006 energy cane variety recorded significantly higher cane yield and fibre % over other varieties.

Intercropping in wide row spaced sugarcane grown under drip irrigation..

Objective:

To study the performance of intercrops in sugarcane planted in wide row spacing.

To study the effect of intercrops on the nutrient status of the soil.

Inference:

Total productivity of the inter cropping systems showed that sugarcane at 1.2 m + green pea followed by ratoon + cucumber produced higher combined cane yield (187 t/ha) along with 9.0 /ha of green pea and 44 /ha of cucumber.

Higher net returns were obtained in sugarcane at 1.2 m + onion followed by ratoon + watermelon. Higher B:C ratio was observed in sugarcane at 1.2 m + onion followed by ratoon + cucumber and sugarcane at 1.2 m + green pea followed by ratoon + watermelon.
