Stress Induced Physiological Alteration of Leaf Relative Water Content, Leaf Proline and Yield of Cotton under Rainfed Agro Ecosystem
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2018, Vol 8, Issue 4
Abstract
Field experiments were conducted at the Regional research station, Aruppukottai, Tamil Nadu during rabi season of 2017-18with the test variety SVPR - 2. To study the effect of in-situ water harvesting, stress management practices on physiological parameters of Relative Leaf Water Content (RLWC), Proline and Seed cotton yield of cotton under rain fedagro ecosytems. The experiments were laid out in split plot design replicated thrice. The main plot treatments consisted of different Insitu water harvesting measures viz., Broad bed and furrows, Ridges and furrows and Compartmental bunding. The subplot comprises stress management practices viz., Soil application of push hydrogel @ 5 kg ha-1 , Soil application of push hydrogel @ 5 kg ha-1 + foliar spray of 1% KCl, Soil application of push hydrogel @ 5 kg ha-1 + foliar spray of 5% Kaolin, Soil application of push hydrogel @ 5 kg ha-1 + foliar spray of PPFM @ 500 ml ha-1,Soil application of push hydrogel @ 5 kg ha-1 + foliar spray of Salicylic acid 100 ppm and Control. The results of this study showed that Broad bed and furrow and Soil application of push hydrogel @ 5 kg ha-1 + foliar spray of PPFM @ 500 ml ha-1 recorded higher RLWC, seed cotton yield and lower values of the Proline content.
