ABSTRACT
An experiment was conducted under farmer’s field of Shyampur sugar mills area, Rangpur under Active Tista Floodplain (AEZ-2) soils of Bangladesh during the cropping seasons of 2013-2014 and 2014-2015. For this study the performance of six released sugarcane varieties viz. Isd 32, Isd 33, Isd 35, Isd 36, Isd 37 and Isd 38 with chickpea. Most of the studied parameters showed significant differences in both seasons. The results revealed that the highest cane yield of 88.41 tha-1 and 92.43 tha-1 was recorded from Isd 37 + chickpea combination followed by Isd 32 + chickpea Isd 38 (80.09 and 79.73 tha-1) and Isd 38 + chickpea (77.54 and 82.52 tha-1) in 2013-2014 and 2014-2015. The highest BCR 2.39 and 2.58 was found also from the combination Isd 37 + chickpea which followed by Isd 32 + chickpea (2.23 and 2.28) and Isd 38 + chickpea (2.17 and 2.36) in 2013-2014 and 2014-2015. Considering the total cost and economic return, different factors associated with production system and farmers’ growing chickpea intercrop with sugarcane varieties Isd 37, Isd 32 and Isd 38 might be recommended at Active Tista Floodplain soils.

Introduction

Sugarcane (Saccharum officinarum L.) is a vegetative propagated perennial crop. It is a high value cash crop and plays vital role in improvement of socio economic condition of farming community, industry and trade situation. It is cultivated in many of the world countries with Brazil as a major producer followed by India, China, Thailand, Pakistan and Mexico (FAOSTAT, 2013). The average cane yield can be improved by adopting improved package of technology and developing high yielding varieties through different breeding techniques (Memon et al., 2004). Intercropping is the practice of cultivating two or more crops simultaneously on the same piece of land per year (Guleria and Kumar 2016) and have many advantages over sole cropping. Intercropping systems result in improved production efficiency, complementary use of resources, weed control, better nutritional quality and higher economic returns (Iqbal, et al., 2019). The growth of sugarcane is slow in early stages and it takes about 3-5 months to establish the full canopy. In early stage of growth, some short duration crops viz: mustard, lentil, potato, onion, tomato, garlic, chickpea and coriander can be grown as intercrop in the vacant spaces between two rows of sugarcane (Alam et al., 2008). On global basis, Chickpea (Cicer arietinum) is the third important pulse crop after dry beans and dry peas in Bangladesh. Intercropping results in an increased farm income and better utilization of resources. The farming community can get inspiration and higher net returns from this system (Akhtar et al., 2010). Considering the fact, a study was undertaken at farmers’ field to evaluate performance of those newly released varieties under rain fed condition with chick pea as intercrop
