Title: GROWTH AND YIELD ANALYSIS OF TOMATO (SOLANUM LYCOPERSICUM) VARIETIES AS INFLUENCED BY TRAINING, IRRIGATION INTERVAL AND POULTRY MANURE USING CORRELATION COEFFICIENT
DEPARTMENT OF AGRONOMY, INSTITUTE FOR AGRICULTURAL RESEARCH, AHMADU BELLO UNIVERSITY, ZARIA&NBSP;
A field study was conducted to study growth and yield analysis of tomato (Solanum lycopersicum) varieties as influenced by training, irrigation interval and poultry manure using correlation coefficient during 2007/2008, 2008/2009 and 2009/2010 dry seasons at the Irrigation Research Station Kadawa farm of the Institute for Agricultural Research, Ahmadu Bello University Zaria in the Sudan savannah zone of Nigeria. The treatments consisted of staking method (staked and un staked), three irrigation intervals (10, 15 and 20 days), two tomato varieties (Petomech VF and UC 82B) and three poultry manure rates (0, 6 and 12 tones ha1 ) The treatments were factorially laid out in a split plot design and replicated three times. The result indicated a positive relationship between fresh yield and yield character such as fresh fruit weight /plant, number of fruits per plant and fruit diameter. In addition, most of the growth components that includes plant height, number of branches per plant and LAI correlated positively with the fresh yield of the crop in all the seasons. In the combined mean a positive and highly significant correlation was observed between fresh yield and fresh weight per plant (0.79**), fruit diameter (0.34**) and LAI (0.13*). The combined contribution showed a greater and positive contribution on the fresh yield by fruit diameter via LAI, plant height via number of branches and number of fruits via plant height. Other combined associations were negative with greater contribution by plant height via LAI. It is therefore concluded that LAI had strong relationship with all growth parameters that influenced developments of yield components. The path coefficient shows that LAI and fruit weight per plant had greater direct contribution to yield in all the three seasons and combined mean on both varieties. Therefore a breeding programme to improve fresh fruit yield should be directed to these components especially number of branches per plant and fruit diameter.
