Abstract

Foliar application is the most efficient method of correcting nutrient deficiencies and increasing crop yield and quality. Nano-fertilizers have a regulated release kinetics to specific sites, making them a smart delivery system. Therefore, a field experiment was conducted at farmer's field of Panjappalli village, Dharmapuri district, Tamil Nadu, India during 2021. To find out the effect of nano zinc and boron on growth and yield of cabbage, the experiment was laid out in randomized block design with 12 treatments replicated thrice. Foliar sprays of micronutrients were given as zinc sulphate @ 0.5%, borax @ 0.25%, nano zinc @ 24 and 30 ppm through Zn EDTA, boron @ 160 and 200 ppm through solubor. The results showed that treatments of irrigation 1.0 PE+100% RDF through fertigation + nano zinc @ 30 ppm through Zn EDTA + boron @ 200 ppm through solubor significantly registered the maximum plant height (31.3 cm), plant spread (61.66 cm), number of non-wrapping leaves (22.83) and leaf area (1618 cm2) at 90 DAT. The same treatment had recorded the highest yield attributes head diameter (18.62 cm), head length (13.53 cm), head volume (1449 cc), head weight (1376 g/plant), yield/plot (74.55 kg) and yield (58.47 t/ha). Therefore, the present investigation concluded that for the better production value of cabbage, application of irrigation @ 1.0 PE+100% RDF through fertigation + nano zinc @ 30 ppm through Zn EDTA + boron @ 160 ppm through solubor was done.
