Effect of nitrogen levels and modified urea on growth and yield of pearl millet (Pennisetum glaucum L.) under rainfed condition

GANAPATI *, A. K. GUGGARI

Abstract


A field study was carried out to find out the effect of nitrogen levels and modified urea on growth and yield ofrainfed pearl millet during 2016 kharif at the Regional Agricultural Research Station, Vijayapur, Northern dry zone ofKarnataka (Zone-3). There were 15 treatment combinations involving three nitrogen levels (25, 50 and 75 kg ha-1) and fivemodified ureas viz., neem coated urea, tar coated urea, sulphur coated urea, vermicompost coated urea and normal urea.The experiment was laid out in a factorial randomised block design with three replications. The results revealed that,application of 75 kg N ha-1 recorded significantly higher grain yield (2878 kg ha-1), stover yield (5.32 t ha-1) and grain weightearhead-1 (42.0 g) compared to 25 kg N ha-1 (2296 kg ha-1, 4.00 t ha-1 and 38.5 g, respectively), however, it was on par with50 kg N ha-1 (2730 kg ha-1, 5.15 t ha-1 and 40.8 g, respectively). Net income and benefit cost were also higher with 75 and 50kg N ha-1 compared to 25 kg N ha-1. Among the modified ureas, neem coated urea recorded significantly higher grain yield(2965 kg ha-1), stover yield (6.13 t ha-1) and grain weight earhead-1 (41.4 g) compared to other modified ureas. Similarly,significantly higher net income and benefit cost ratio were recorded with application of neem coated urea (` 32316 ha-1 and3.32, respectively) as compared to application of normal urea (` 23317 ha-1 and 2.69, respectively) and other modifiedureas.
