ABSTRACT An investigation was carried out on sandy loam soils of semi arid regions of southern Telangana to analyze the potential of drip irrigation along with mulch on fruit yield, water and nutrient use efficiency as well as economy. The treatments of present study were comprised of two levels mulching (M0-without mulch and M1 with mulching, respectively), with silver Polyethylene of 100 micron thickness were used and two levels of irrigation (I1 -75% and I2 100% ETc through drip). There were two levels of irrigation as main plot and two levels of mulching in the sub plot together constituting four treatment combinations with five replications under factorial randomized block design. Taking into account the scheduling of irrigation at different levels of ETc and mulching were used in the treatment combination: I1M0-75% ETc + No mulching, I1M1- 75% ETc + with mulch, I2M0- 100% ETc + No mulching and I2M1- 100 % ETc + with mulch. The study revealed that drip irrigation 100 % ETc along with silver polythene mulch showed better performance in terms of yield, water use efficiency, nutrient use efficiency as well as economics. Maximum yield of 89.11 kg tree-1 combination of 75 % ETc + with mulching has proven the maximum water use efficiency (5.54 g liter-1 water consumption) and fertilizers use efficiency (0.89 q kg-1 fertilizer application) however along with maximum net return of 400973. 90 ₹ ha-1, net return of 346873.90 ₹ ha-1 per hectare and B: C ratio of 7.41 was recorded in I2M1 (100 % ETc + with mulch). So the experiment suggests that drip irrigation along with mulch has the potential to provide greater benefit by optimizing the use of water resources. But the interaction of 75 % ETc + with mulching has proven the maximum water use efficiency (6.28 g liter-1 water consumption). |
