Screening of Potato Varieties under Litchi Based Agroforestry System

Aims: To evaluate the performance of eight potato varieties and identify the best variety under litchi based Agroforestry system.

Study Design: The treatments were laid out with two factors RCBD following three replications.

Place and Duration of Study: Study was carried out at Agroforestry Research Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur during November 2014 to March 2015.

Methodology: There are two factors, factor A was two production systems; S1= Litchi + potato and S2=Potato sole cropping, another factor B was eight potato varieties; V1=Diamond, V2= Cardinal V3=Asterix, V4=Carage, V5=Lady Rosetta, V6=Granula, V7=Raza and V8=4.26R. Data are collected on plant height, leaf length, leaf breath, no. of leaf per shoot, no. of shoot per hill and yield ton/ha.

Results: The result of the experiment revealed that there was a significant effect of different variety and production systems on the growth and yield contributing characters of potato. Significant effect of eight potato varieties and production system was found on the plant height, leaf length, leaf breath, no. of leaf per shoot, no. of shoot per hill and yield. The highest tuber yield (18.88 tha-1) was recorded in Lady Rosetta potato variety whereas the lowest tuber yield (12.29 tha-1) was recorded in Diamond.

Conclusion: The suitability of the cultivation of different potato variety under litchi based Agroforestry systems may be ranked as Lady Rosetta> Granula> Asterix> Carage >Raza> 4.26 R > Cardinal > Diamond.
