ABSTRACT
An experiment was conducted in different farmer’s field conditions at Joypurhat, Jamalpur, Hobigonj and Barishal during the cropping season of 2016-2017. The study was undertaken with a view to evaluating the performance of three sugarcane genotypes viz. I 124-07, I 133-07 and I 149-08 against standard variety Isd 36.The findings of the study revealed that the highest number of tiller (379.20 x103 ha-1) was found at Jamalpur while the lowest was recorded at Barishal (89.25 x 103 ha-1). The highest millable cane was produced at Jamalpur (158.20 x 103 ha-1) and the lowest (75.50 x 103 ha-1) was recorded at Barishal. Among four locations, the highest mean cane yield was recorded at Barishal (123.28 tha-1) while the lowest cane yield was obtained at Hobigonj (52.71 tha-1). Highest brix % 22.36 was also recorded at Hobigonj whereas the lowest brix % was recorded at Jamalpur (18.00%).
Key words: Performance, genotypes, farmers’ condition.

Introduction

Sugarcane (Saccharumofficinarum L.), a vegetative propagated perennialplant is a cash crop and main source of raw material for production white sugar and gur in Bangladesh. Itis cultivated in mainly in Brazil followed by India, China, Thailand, Pakistan and Mexico (FAOSTAT, 2013). In Bangladesh, on an average 4.5 million metric tons of sugarcane is produced annually from 0.12 million hectares of land. In addition, presently average cane yield in Bangladesh is around 46 tha-1 with average recovery of sugar is around 7.0% which is quite low in comparison to other sugarcane growing country (Islam et al. 2017). The sugarcane yield of a particular variety depends upon the heredity potential of the genotype and the environment where it is exposed during the course of its life cycle (Yadava, 2003). Variety of a crop plays an important role as regards to the yield and quality; sugarcane is no exception. Sugar industries in Bangladesh continuously need high yielding and high sugar varieties. After a considerable period of cultivation sugarcane varieties show a tendency to decline in yield and vigor. It is an obscure and puzzling problem to scientists, growers and processors. To maintain high yielding, it is necessary to replace varieties every few years with new genotype. It is necessary to ensure the performance of a promising clone in particular locations before recommendation. So, the present study was undertaken to ascertain the performance of promising genotype to requirement for varietal improvement in Bangladesh.
