Field experiment was conducted in 2013 2014 at Precision |
|
Farming Development Centre research farm, |
|
Tamil Nadu Agricultural University, Coimbatore. To study |
|
the effect of drip fertigation and plastic mulching on |
|
the plant |
|
growth and yield attributes of chilli (Capsicum annuum |
|
L). The experiment were laid out factorial randomized |
|
block |
|
design which included three fertigation levels 80, 100, |
|
and 120 per cent Recommended Dose of Fertilizers (RDF) and |
|
three different mulching treatments 25, 50 micron Black |
|
Plastic Mulch (BPM) and no mulch which were replicated |
|
thrice. In chilli maximum yield of 128 numbers of fruits |
|
plant-1 which is worked out as 12.27 t ha-1 was observed |
|
for the |
|
treatments T3. The total quantity of water applied |
|
uniformly to all the treatments was 75.83 litres as per |
|
the crop water |
|
requirement. Maximum water use efficiency observed in T3 |
|
(66.36 kg ha-1.mm-1). The maximum N, P and K fertilizer |
|
use |
|
efficiency of 109.95 kg ha-1, 164.94 kg ha-1 and 164.94 |
|
kg ha-1 respectively, were observed in T1. The highest |
|
benefit cost |
|
ratio was recorded under both T2 (BPM of 25 micron |
|
thickness with 100 per cent RDF) and T3 (BPM of 25 micron |
|
thickness with 120 per cent RDF). From economic viability |
|
point the T2 treatment registered results that were |
|
economically viable with highest profit. Increased yield |
|
in fertigation treatments might be due to better |
|
availability of |
|
plant nutrients and irrigation water throughout the crop |
|
growth period under drip fertigation system. |
