| Summary, etc. |
The present study ‘growth and yield analysis of top worked cocoa (Theobroma cacao L.) plants’ was conducted during October 1994 to March 1996 at the College of Horticulture, Vellanikkara, Trichur. A total of 590 top worked cocoa plants of two age groups, top worked with 29 high yielding clones were utilised for the study. Observations of 143 top worked plants of first set were taken for a period from April 1994 to March 1996 which corresponds to a lapse of 36 to 66 months after top working. Those of second set were taken for the early period of bearing, from April 1995 to March 1996 which corresponds to a lapse of seventeen months after top working. Stock effect on the performance of top worked plants was measured in terms of pre – experimental girth (a year prior to top working) and pre experimental yield (two year period prior to top working) of these plants prior to top working. Differences in growth vigour as a factor influencing yield was judged by assessing leaf area index. There were large differences in the yield of top worked clones both between and within plants of the same clone. The interclonal differences explainable as due to genetic factors were more than intraclonal differences. There were also large intra clonal plant to plant difeerences in yield. Part of this intraclonal variation was attributed to stock effect. However, this stock effect persisted only in the early years. One of the important factors responsible for the intraclonal differences in yielding ability was the differences in growth vigour as judged by leaf area index. Clones that were identified as scions superior for top working were GII -19.5, GVI – 51, GI-5.9,M-16.9 and GVI-68. Top worked plants come to bearing in about a year after the operation and as much as 44 per cent of the pre-experimental yield was recovered after seventeen months. The extent of yield advantage after yield stabilisation was 92 per cent. |
