Abstract:

The experiment was carried out to “Study of effect of level of fertigation through drip irrigation on yield and Calculation of nutrient use efficiency of Marigold crop in different treatments” November 03 to January 19 at college of Agricultural engineering, Madakasira, Anantapur, (dist). The objective was to work out the four different levels of marigold and to compare the performance of yield, quality parameters, and nutrient use efficiency. The experimental field with 570 m2 (19 x 30m) installed with drip irrigation system was selected for experimentation. The field was divided into 4 sub plots. Each subplot has dimensions of 19 x 7.5 m. Each subplot was allocated with 16 laterals. For each lateral 64 marigold seedlings were transplanted at 40cm spacing. Each plot was planted with the experiment was a Complete Randomized Design (CRD) with 4 treatments. Inca II variety of marigold crop was selected for experimentation. Inca II variety plants have less height and more number of short branches and are majorly used for growing as cut flowers, land scalping in lawns and gardens. The highest yield was recorded in T1 followed by T3, T2 and T4. The highest contribution of yield was by T1 as 36% of total yield of experimental plot. Next highest yield was observed in T3 as 25% followed by T2 as 24%. Lowest yield was observed in T4. The highest nitrogen use efficiency was observed in T2 followed by T4 and T3. The highest phosphorus use efficiency was observed in T2 followed by T1, T4 and T3. The highest potash use efficiency was observed in T2 followed by T1, T4 and T3. It clearly shows that the nutrient use is high if the fertilizer was applied through drip irrigation. It has also reveals that the requirement of fertilizer is also less through drip irrigation.
