Abstract:
The experiment was conducted to evaluate the "Study on growth, yield and yield contributing characters of tomato varieties in rainfed area" during October 2013 to March 2017 at the experiment field of Kalikapur, Baraigram Upazila, Natore and laboratory of Crop Science of Technology, Rajshahi University, Bangladesh. Four different experiments were conducted and laid out in Randomized Complete Block Design with three replications. Four tomato varieties BARI-2, BARI-8, BARI-14, and BARI-15 were used as planting material. A series of experiment were laid out in order to develop suitable variety, better management practices and to get high quality tomato production to overcome the adverse condition. Experiments were conducted mainly effect on staking and non-staking, pest and disease management practices, pruning and non-pruning & organic and inorganic fertilizer combination level of growth, yield and yield contributing characters of tomato variety. In case of quality tomato production, the results revealed that the plant height, number of leaves, number of branches per plant, number of fruits per plant, yield ton per hectare were significantly influenced by treatments except few cases. Results revealed that the effects of Staking and Non-staking and their co-ordinate interactions of tomato have been investigated and produced the highest yield (54.85 t/ha) was observed in staking practices and the highest yield was found (63.03 t/ha) in combination and vitamin C content highest in fresh stage (30.00 mg/100gm) as obtained from the treatment S1V1 (S1= Staking; V1= BARI-2). The effects of pest and disease management practices produced the highest yield (53.26 t/ha) was observed in C1 (Chemical use) and very closest yield was found (50.88 t/ha) in NL1 (Neem leaf extract & Bordeaux mixture). The treatment combination of pruning and non-pruning practices observed the maximum yield (53.25 t/ha) in used pruning practices and the highest yield was found (61.43 t/ha) in the treatment P1V1 combination (P1= Pruning; V1= BARI-2). On the other hand, among different organic and inorganic fertilizer combination the highest yield of tomato (57.47 t/ha) was found in treatment T2= ½ Cow dung + ½ chemical fertilizer (7.5ton/ha + Urea-250kg/ha, TSP-200kg/ha, MOP-100kg/ha) with variety BARI-2 (Ratan) followed by poultry litter and chemical fertilizer.
