  Cashew is the best income earning plantation crop of south eastern tropical regions in the coastal sandy and alluvial soils. Cashew has received adequate research attention in vegetative propagation, but its improvement for higher yields and high-density planting is still a necessity. To reach this milestone in research, an attempt was made twice experimentally at the cashew research station in Bapatla to identify the best method out of two techniques of soft-wood grafting (SWG) developed with different aged rootstocks of BPP-5 and scionsticks of BPP-6 cultivar under eight shade providing structures with a control in light, temperature and relative humidity for a period of seven months in three replications. The results revealed that a lesser aged (35-45 days old) rootstock with less number (only two) of leaves was prolific to give sufficient foliage after successful graft union using SWG under HDPS (high density polythene sheet) shade nets and low-cost structure like trench and a structure with coconut fronds. Significant differences were observed for all the growth traits except for height. These structures were providing a partial shade of 10 to 50 percent with success in sprouting (65.58%) and graft-take (50.1-59.81%) in a short period of time. All these structures with high success percentage provided more than 80 percent photosynthetically active radiation to the SWGs. Major achievement is attributed to identification of (1) reduced age of rootstock at 35 days for Bapatla method and 45 days for Puttur method (2) a prior requirement of shade for 20 days (3) a low-cost structure like shallow trench was suitable for microclimate required for successful SWG in cashew in our region. In this study, the rootstock BPP-5 was potential for producing more than 80 percent of successful SWGs made during the study period. For the establishment of new orchards with high density planting, genetically competent, prolific scion cultivars with high yield potential like BPP-6 were essential, though identification of its dwarfing rootstock is still a lacuna in cashew research.
