Abstract :

Low rainfall and scarcity of irrigation water severely affect cultivation of vegetables. Therefore, efficient utilization of limited water for the best crop growth and development is of great concern. The hydrophilic polymers are regularly supplying water to the plant based on its need and are greater use in storing water about 100-300 times of their own weight. They can play a vital role in stress alleviation at appropriate time as needed by the plants. Hence this study was undertaken to assess the efficacy of hydrophilic polymers severally and in combination with organic and inorganic fertilizers on growth, yield and quality of tomato cv. CO3. The results revealed that the application of polymer TerraCottem 4.5 g per plant with recommended dose of manures and fertilizers (FYM 25 t + NPK 150: 100:50 kg + Azospirillium 2kg + Phosphobacteria 2 kg ha-1) followed by Polyvinyl alcohol 15.0 g per plant with recommended dose of manures and fertilizers improved the growth, yield and quality of rain fed tomato .
