ABSTRACT
During August 2014 to May 2015 and May 2015 to February 2016, a field experiment was conducted at College of Agriculture, Thiruvananthapuram, Kerala to study the performance of tannia intercropped in coconut gardens. Split plot design with four replications were used for study. The four main plot treatments were conventional tillage followed by pit system (l1), conventional tillage followed by mound system (l2), deep tillage followed by pit system (l3) and deep tillage followed by mound system (l4). The sub-plot treatments were combinations of three soil conditioners (S1- control, S2- coir pith, s3- rice husk) and two nutrition systems (n1- INM and n2- organic nutrition). Results of the experiment revealed that the performance of tannia in terms of growth and yield were improved by adopting deep tillage with planting done in pits. By using coir pith as soil conditioner and by providing organic nutrition in split doses at 2MAP, 4 MAP and 6 MAP higher biometric characters and yield was obtained.
