Effect of water soluble fertilizers through drip irrigation on yield attributes of marigold crop

R Snehitha, CH Sneha, D Lakshmi Kalyani, P Sravani and T Sumanth
Drip irrigation is an irrigation method that saves water and provides the most economical method of applying fertilizer by utilizing fertilizer injectors that operate without any external power supply. Fertigation use soluble fertilizer that flow directly towards the plant root zone through the drip system, drip emitters or micro sprinkler system. A liquid fertilizer solution or soluble fertilizer is injected into the system at the desired rate. Proper application of fertilizers through different source play a vital role enhancing vegetative growth and quality flower production. The field experiment was conducted to study the effects of fertigation on growth parameters of African marigold in the farm, College of Agricultural Engineering, Madakasira, Anantapuram district nearest to Karnataka state border, which is geographically situated at 13°56’56.7” N latitude, 77°18’42” E longitude and at an altitude of 641 m above the mean sea level in the Southern Agroclimatic Zone (Zone IV) of Andhra Pradesh. The annual rainfall of Madakasira is 508 mm. Due to water scarcity, the available water resources should be very effectively utilized through water saving irrigation technologies. African marigold is a popular flower crop grown throughout the world on commercial scale. Marigold stands first among the loose flowers in Goa and its requirement increases in many folds on special occasions like Ganesh Chathurthi, Dussera, Diwali, weddings etc. The soil was collected and analysed in Regional Agricultural Research Station (RARS), Tirupathi and water for irrigation is taken from bore existed at College of Agricultural Engineering, Madakasira was tested. The experiment field with 810 m2 (18x 45m) installed with drip irrigation system was selected for experimentation. The field was divided into 6 sub plots and laid out in randomised block design with different doses of water soluble fertilizers given through drip with following treatments viz., T1 – Control (no fertilizers), T2 – 100% RDF (Recommended Dose of Fertilizers) through conventional (Urea, SSP, MOP) fertilizers, T3 – 100% Nitrogen through drip, T4, T5 and T6 – 100%, 75% and 50% RDF through water soluble fertilizers. The yield attributes like number of flower buds, number of flowers, flower surface area, fresh weight of flowers, no of pickings, no of flowers per kilogram and flower yield per plot were studied. The average number of branches, flower buds and maximum flower sizes were highest in T4 100% RDF and lowest was observed in T1– Control (no fertilizers). The highest yield was recorded in T4 followed by T5, T3, T2, T6, and T1.
