 ABSTRACT

A field experiment was conducted during 2015-16 and 2016-17 at Regional Sugarcane and Rice Research Station, Rudrur to study the effect of drip fertigation on yield and water productivity of sugarcane. The test variety ‘93 V 297’ was planted in wider rows (150 cm). The experiment was designed with four treatments viz., drip fertigation with 75% RDF (F1), drip fertigation with 100% RDF (F2), drip fertigation with 125% RDF (F3) and surface irrigation with soil application of RDF (F4). The results revealed that, drip fertigation with 125% RDF showed 26 % increase in cane yield of plant crop, 47 % increase in cane yield of ratoon crop over surface irrigation with soil application of fertilizers. The higher net returns of Rs.79,584/- and Rs.78,851/- obtained with plant and ratoon crop, respectively with drip fertigation @125% RDF over surface irrigation with soil application of fertilisers. The drip irrigation used less quantity of water (1236 mm) and saved 20 % water over surface irrigation method. The highest water productivity (13.6 and 7.6 kg m-3) recorded with 125 % RDF which was 40 and 83 % higher over surface irrigation with soil application of fertilizers in plant and ratoon crops, respectively. Hence, Drip fertigation with 125% RDF through water soluble urea and MOP applied at weekly intervals starting from 45 DAP to 180 DAP was found suitable for productive sugarcane cultivation in Northern Telangana Zone.

Key words: Drip Fertigation, Nitrogen, Potassium, Sugarcane, Water Productivity.
