Description A field experiment was conducted at Water Technology Centre, College farm, College of Agriculture, Rajendranagar, Hyderabad during Rabi, 2011-12 to study the “Effect of drip irrigation levels and mulching on tomato productivity”. The experiment was laid out in strip plot design with three drip irrigation levels as main treatments (viz., I1 - Drip irrigation at 1.0 E pan, I2 - Drip irrigation at 0.8 E pan, I3 - Drip irrigation at 0.6 E pan) and four mulches (viz., M1-bio-degradable mulch, M2-polythene mulch, M3-paddy straw and M4-no mulch) as sub treatments and were replicated thrice. The experimental soil was sandy clay loam in texture with low in available nitrogen, high in available phosphorus and potassium.
The plant height and dry matter production were maximum with drip irrigation scheduled at 1.0 E pan at all the growth stages and application of polythene mulch.
Significantly higher total number of fruits per plant, fruit yield per plant and total fruit yield was observed in drip irrigation scheduled at 1.0 E pan with application of polythene mulch (54.00 plant-1), (2.70 kg plant-1) and (36.78 t ha-1) while the less number of fruits (42 plant-1), yield plant-1 (2.10 kg) and fruit yield (27.25 t ha-1), respectively were observed with irrigation schedule at 0.6 E pan without mulch.
Total NPK content in tomato fruits and haulms at harvest was not significantly influenced by both irrigation levels and mulches. Significantly higher uptake of N, P and K was observed with drip irrigation scheduled at 1.0 E pan and was on par with drip irrigation scheduled at 0.8 E pan in both haulms and fruit. Similarly application of polythene mulch also recorded significantly higher uptake of NPK.
Drip irrigation scheduled at 0.6 E pan recorded higher water use efficiency (122.88 Kg ha mm-1). The least WUE was observed in drip irrigation at 1.0 E pan. On the other hand maximum WUE was recorded with application of polythene mulch (112.87 Kg ha mm-1) while the least was recorded with no mulch (94.88 Kg ha mm-1).
Drip irrigation scheduled at 0.6 E pan recorded the highest total soluble solids and ascorbic acid content and it was significantly superior to rest of the irrigation levels. Application of polythene mulch recorded significantly higher total soluble solids and ascorbic acid content at harvest and superior to rest of the mulch treatments. Drip irrigation scheduled at 1.0 E pan and application of polythene mulch recorded significantly higher juice content over other treatments. Significantly lower weed density and dry matter was observed with application of polythene mulch compared to all other mulches.
Maximum net returns (Rs. 1, 29, 551 ha-1) and B:C ratio (3.34) were associated with drip irrigation scheduled at 1.0 E pan while the least net returns (Rs.1, 10, 444 ha-1) and B:C ratio (2.93) were observed with drip irrigation scheduled at 0.6 E pan. Application of polythene mulch recorded maximum net returns (Rs. 1, 30, 999 ha-1) and B:C ratio (3.34).
From the present study, it can be concluded that drip irrigation scheduling at 1.0 E pan with application of polythene mulch will be the best combination for getting higher tomato fruit yield and net income under the present Agro climatic conditions of semi arid tropics.
