| Popis: | The present study was conducted during 2017-18 to 2019-20 for three (3) years to assess the performance of high yielding tuberose variety Arka Prajwal in Nellore district of Andhra Pradesh. The improved variety Arka Prajwal was planted along with local variety (Suvasini) as check in 0.2ha each in the fields of five farmers at Veguru and Leguntapadu villages of Kovurumandal of Nellore district during the year 2017 and continued for three years. The results revealed that among the two varieties Arka Prajwal recorded significantly higher number of spikes per plant (1.86 no./plant), number of florets per spike (31.88 no./spike), 100 Nos florets weight (173 g), flower yield per plant (102.46 g) and flower yield per hectare (8.75 t/ha). The economic parameters viz., benefit cost ratio (2.84), marginal benefit cost ratio (22.28) and relative economic efficiency (2.80) were recorded more in Arak Prajwal than Local variety. The Arka Prajwal variety showed superiority over Local variety and found suitable for Nellore district of Andhra Pradesh. Extension gap (yield gap) refers to the difference between demonstration plot yield and actual yield (farmers practice) and it was 4.64 t ha-1. There was 25.78 per cent reduction in yield as compared to demonstration plots yield. A sizable total yield gap of 13.36t ha-1 was observed and it accounted for 74.22 per cent. |
