PHYSICOCHEMICAL CHARACTERISTICS OF SOME TOMATO VARIETIES (Lycopersicon esculentum Mill) AS INFLUENCED BY SEACING, STAKING AND PRUNING.

Abstract

Marglobe and S-12 varieties gave heavier fruits than H S. 101. Widest spacing also produced significantly heavier fruits than other spacings. Pruned plus staked plants produced fruits of greater weight. In Marglobe and S 12, pruning and staking induced higher weight per fruit The effect of pruning in increasing the weight per fruit was enhanced due to wider spacing Maximum and minimum number of I grade fruits were obtained from Marglobe and S-12, respectively. Maximum number of l grade fruits were from S-12. Maximum and minimum II grade fruits were obtained from HS 101 and $-12 respectively. As the spacing increased I grade fruits were also increased Staking and pruning also increased the I grade fruits. Staking and pruning tended to increase the juice percentage in fruits. Staking and pruning appeared to increase the acidity. Tomato pulp of S-12 variety contained relatively higher reduc- ing sugar Staking and pruning appeared to increase the total sugar. Vitamin C content was significantly lower in Marglobe than H.-S 101 and S-12. Widest spacing (60 x 60 cm³) significantly increased the Vitamin C over the other spacings (45 x 45 cm² and 45 x 30 cm³). Pruned and staked plants produced fruits of significantly higher Vitamin Cover plants.
