Assessment of Improved Variety of Tuberose (Polianthes tuberosa) Prajwal for Yield and Economics in Western Parts of Chittoor District of Andhra Pradesh

Abstract

The present study was conducted during 2015–2018 for three years to assess the performance of high yielding tuberose variety Prajwal for western parts of Chittoor district of Andhra Pradesh. The improved variety Prajwal was plated along with local variety Hyderabad single as check in 0.2ha each in the fields of five farmers at Ayyavaripalli and Chinnagangulavaripalli villages during June 2015 and continued for three years. The results revealed that among the two varieties Prajwal recorded significantly higher number of spikes per plant (2.86 no./plant), number of flowers per spike (46.9 no./spike), flowering duration of spike (16.55d), spike length (105.88cm), flower weight per spike (55.31g), 100 flower weight (91.80g), flower yield per plant (165g) and flower yield per hectare (17.7t/ha). The economic parameters viz., benefit cost ratio (2.22), marginal benefit cost ratio (26.5) and relative economic efficiency (12.92) were recorded more in Prajwal than Hyderabad single. The Prajwal variety showed superiority over Hyderabad single and found suitable for western parts of Chittoor district of Andhra Pradesh.
