Abstract
In the present study, comparative advantages were computed to check on the existing status of cultivation practices with the precision farming practices. The study would be helpful to the tomato industries to manage their supply chain effectively by minimizing the cost and increasing the marketing efficiency and thereby enhancing their profit. Study was conducted in the Department of vegetable crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu from 2007 to 2010. Field experiments were conducted in two different fields of villages at Saragapalli, Krishnagiri district to obtain the best results from harvesting of tomatoes at three different maturity stages from two different farming systems. Harvested fruits were transported from Hosur to Coimbatore. The treatment F2M1 (Harvesting at mature green stage of precision farming tomato) was found to be better because the lowest enzymatic activities with increased shelf life of 28.50 days. Key words: Maturity stages, tomato, precision farming, post harvest, shelf life.
Highlights
Tomato is known for its rapid deterioration and poor shelf life due to diverse factors such as thin fruit peel, low firmness, slow rate of conversion of sugars, high pH, high rate of deterioration and high ethylene production
Field experiments were conducted in two different fields of villages at Saragapalli, Krishnagiri district to obtain the best results from harvesting of tomatoes at three different maturity stages from two different farming systems
Consequent to the introduction of precision farming system to Tamil Nadu, India, nearly 80% of the area under tomato was brought under this system and nearly 20% alone being cultivated under conventional system
Summary
Tomato is known for its rapid deterioration and poor shelf life due to diverse factors such as thin fruit peel, low firmness, slow rate of conversion of sugars, high pH, high rate of deterioration and high ethylene production. In order to sustain the productivity and profitability of tomato in the years to come, both the post harvest management of produce and supply chain management need to be studied together to address the issues of post harvest loss and to maximize the farmer’s share of consumer price. In this context, the present study on comparative study of maturity stages influenced by tomato growing under different production systems was taken up with the objective to study the effect of maturity stages as the elements of post harvest management of tomatoes grown under conventional and precision system of farming. It is a refinement of good whole field management, where management decisions are adjusted to suit variations in resource conditions
