Abstract/Description: | A field experiment was carried out during spring-summer of 2006 and 2007 at Indian Institute of Vegetable Research, Varanasi. The treatments comprised 4 levels of surface irrigation (4, 7, 10 and 12 days intervals) and 2 level of mulch (pea straw mulch at 12.5 tonnes/ha and ‘no mulch’). Significant differences on morpho-physiological and yield attributes were observed in various irrigation treatments and organic mulches. Irrigation scheduled at 4-day interval exhibited maximum fresh pod yield of okra (15.03 tonnes/ ha) with higher leaf water potential, (0.91 MPa), relative water content in leaves (83%), photosynthetic rate (14.10μmole CO2/m2/s1) and stomatal conductance (351.9 mmol H2O/m2/s1). Higher chlorophyll concentration index was recorded in 4 or 7-day irrigation intervals. Pea-straw mulch significantly enhanced the plant height, number of nodes/plant, number of pods/plant, pod weight and fresh pod yield over non-mulched. Significant improvement was observed in plant physiological parameters and soil water content under pea straw mulch. Irrigation at 10-day interval along with pea-straw mulch exhibited maximum water-use efficiency (455.72 kg/ha-cm). Significant reduction in weed population (65.4%) and considerable water savings (29.6%) was recorded with use of pea-straw mulch over no mulch. |
