Effect of micro irrigation on growth, yield and quality of sardar guava under semi arid conditions of Rajasthan
Keywords:
Drip irrigation, guava cv. L-49, semi-arid, Sardar guavaAbstract
A field experiment on guava (Psidium guajava L.) cv. Sardar was carried out at Department of Horticulture, Udaipur. There were seven treatments i.e., drip irrigation at 25%ET through 2drippers/ plant per day (T1), irrigation at 50% ET through 3 Drippers/plant daily (T2), irrigation at 75% ET through 4 drippers/plant daily (T3), irrigation at 25% ET through 2 dripper/plant on alternate day (T4), irrigation at 50% ET through 3 dripper/plant on alternate day (T5) and irrigation at 75% ET through 4 dippers plant on alternate day (T6) and conventional flow irrigation at 0.75 CPE (T7). Plants were planted at a spacing of 6x6metre under randomized block design with three replications and age of plant three years. Result revealed that the irrigation at 75% ET through 4 dippers per plant per day (T3) exhibited significantly higher plant height (350 cm), canopy volume (24.83 cubic metre), fruit weight (135g) and per plant yield (14.89 kg). While, in quality wise highest TSS in T3 (irrigation at 75% ET through 4 drippers/plant daily) and vitamin C content in control (T7).
