Abstract

A field experiment was conducted during rabi seasons of 2019-20 at Instructional Farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner to study the response of Barley (Hordium vulgare L.) to different sources of phosphorus in Arid Region of Rajasthan The treatments comprising of 12 combinations of phosphorus sources viz., PROM, DAP, SSP, PROM + DAP (1:1), PROM + SSP (1:1), DAP + SSP (1:1), PROM + DAP (2:1), PROM + SSP (2:1), DAP + SSP (2:1), PROM + DAP (1:2), PROM + SSP (1:2) and DAP + SSP (1:2). The experiment was laid out in randomized block design with three replications. The results revealed that application of PROM + DAP (2:1) recorded significantly higher plant height at 60 DAS and at harvest, dry matter accumulation at 30, 60, 90 DAS and at harvest, crop growth rate at 30-60 and 60-90 DAS, relative growth rate at 30-60 DAS and 60-90 DAS, total number of tillers m-1 row length, number of effective tiller m-1 row length, grains spike-1, spike length, test weight grain, straw and biological yield, phosphorus content in grain and straw, nitrogen and phosphorus uptake by grain, straw and their total uptake but remained at par with PROM + SSP (2:1), PROM + DAP (1:1) and PROM + SSP (1:1). However, crop growth rate at 90 DAS-at harvest was higher with DAP + SSP (1:2). Highest net return (` 44273 ha-1) with B:C ratio of 2.42 was also obtained under application of phosphorus as PROM + DAP (2:1)

Conclusion

Application of PROM + DAP (2:1) is remunerative in maximizing the yield of barley on loamy sand soils of Agro-climatic zone I-C. This treatment significantly provided the higher grain yield (3621 kg/ha) and net returns (` 44273/ha). However, these results are only indicative and it requires further experiment to arrive at good consistent as well as final conclusion
