Abstract
A balanced nutrition for enhanced nutrient use efficiency is important to achieve potential crop yield. A deficiency of secondary and micronutrients is known to impair growth and quality of oil seed crops such as sunflower. The present study examined the effect of foliar application of nano-scale zinc particles in combination with boron on the growth and yield attributes of sunflower cv. RFSH-130 in a controlled environment. The treatments comprised foliar application of different nanoparticles (ZnS @ 400 ppm and ZnO @ 1000 ppm) and conventional ZnSO4@ 5000 ppm at 35 and 55 DAS. Further, these were combined with or without spray of boron @ 0.5% at 40 DAS. The sizes of the green synthesized nanoparticles of ZnS and ZnO in the presence of a biopolymer, chetosan were 60 and 38 nm respectively. ZnS and ZnO in nano formulations were absorbed by sunflower foliage to a greater extent compared to bulk ZnSO4. The results revealed that green synthesized ZnS and ZNO nanoparticles enhanced the growth and yield of sunflower.
Highlights
Can augment the supply of edible oils considerably [1]
There are reports indicating that nano scale zinc oxide particles increased stem and root
Oilseed crops constitute a major part of nutrition in human beings and globally, sunflower (Helianthus annuus L.) ranks second next to soybean among annual field crops grown for edible oil
Summary
A composite soil sample was collected and the area, promote better absorption and translocation even soil was air dried and sieved through 2 mm mesh. The at low concentrations have proved to be effective in initial properties of soil were analyzed following standard enhancing plant growth, development and yield of oil seed crops. Similar results with the use of nano ZnS protocols
