Abstract

A present field investigation was entitled was conducted at the instructional farm of Barrister Thakur Chhedilal, College of Agriculture and Research Station, Bilaspur (C.G.) during kharif season 2021-22. The experimental treatment consists three drip irrigation levels at I1: 100 % PE, I2: 80 % PE, I3: 60 % PE and control plot (I4) with surface irrigation and same as three levels of nutrient management with F1: 100 % RDF through soil application, F2: 100 % RDF through water soluble fertilizer (WSF), F3: 75 % RDF through WSF and farmer control. The turmeric cultivar Narendra was used and each treatment was replicated thrice in strip plot design. A major problem associated with drip irrigation systems is the clogging of emitters, Clogging can reduce emission rates and cause poor uniformity of water application. Clogging also increases the maintenance costs, as it becomes necessary to check, repair or replace clogged emitters and other components. Chemical treatment and proper filtration of water was prevent or correct emitter clogging. The results of experiment show pre harvest observation viz., plant height, number of leaves, dry matter production and crop growth rate and post-harvest observation viz., number of mother and finger rhizome, length and girth of mother and finger rhizomes, rhizome yield (t ha-1) and irrigation observation viz., water expense, water expense efficiency (WEE) and number of irrigations in turmeric. Under drip irrigation level treated with 100 % PE (I1) and fertigation level at 100 % RDF (F2) through water soluble fertilizer in turmeric were found significantly superior among entire treatments with regard of above specified character. Irrigation level I3 and nutrient management F1 observed significantly inferior among entire treatments. Drip irrigation scheduling with 100 % PE in every two days and WSF through drip irrigation with 100 % RDF, is recommended for obtain maximum turmeric production (25.10 t ha-1 and 25.88 t ha-1), maximum net returns (Rs 1079480 ha-1 and Rs 1116074 ha-1) and Benefit: cost ratio (6.15 and 6.27) together with WEE (72.31 Kg ha-mm-1) and 77.21 Kg ha-mm-1) in drip irrigation systems.

Conclusion

In the drip irrigation levels it was concluded that 100 % PE (I1) and 80 % PE (I2) found equally effective in terms of growth characters (plant height, number of leaves, dry matter production, crop growth rate) and yield parameter (number of mother and finger rhizome, weight of mother and finger rhizomes plant-1) and as compared to other drip irrigation and surface irrigation. In nutrient management, 100 % RDF through WSF was superior increase of growth characters (plant height, dry matter production, crop growth rate) and yield parameter (number of mother and finger rhizome, weight of mother and finger rhizomes plant-1). Drip irrigation level at 80 % pan evaporation (at alternate days) and nutrient management at 75 % RDF applied through water soluble fertilizer is recommended to achieve maximum turmeric yield 25.49 t ha-1, net return Rs 1097777 ha-1 and Benefit: cost ratio 5.67 and WEE 74.76 kg ha-mm-1, under drip irrigation.
