Dynamics of chitosan based NPK-nanofertilizers in greenhouse cucumber production system

Abstract

Aim: To study the effect of NPK-nonofertilizers on growth, reproductive and yield parameters as well as nutrient recovery efficiency in greenhouse cucumber. Methodology: The performance of greenhouse cucumber cultivar KPCH-1 was studied using six treatments namely 100% RDF(90:75:75 kg ha-1) through water soluble fertilizer (WSF), 60% RDF as nanofertilizer, 50% RDF as nanofertilizer, 40% RDF as nanofertilizer, 30% RDF as nanofertilizer and absolute control. Growth, reproductive and yield parameters of greenhouse cucumber as well as nutrient use efficiency were assessed during cropping period. Results: The plants administered with 60% RDF through nano-fertilizer showed12.07%, 11.85% and 15.72% higher increase in leaf area at 30 and 60 DAS as well as at final harvest, respectively, over 100% RDF through WSF. The greenhouse cucumber fertigated with 40% RDF as nanofertilizer recorded maximum number of pickings and number of fruits per vine accounting for maximum increase in marketable yield compared to WSF. The cucumber plants administered with 40% RDF as nano-fertilizers also recorded maximum apparent N, P and K recovery efficiency. Interpretation: Nano-fertilizers have ability of controlled release of desired nutrients at their site of action. Despite of lower concentration, higher yield obtained at 40% nano-NPK fertilizer was associated with high nutrient recovery by nanofertilizers.

Utilizing Urea–Chitosan Nanohybrid for Minimizing Synthetic Urea Application and Maximizing Oryza sativa L. Productivity and N Uptake

“…The previous investigations have focused only on the interaction mechanism between urea and chitosan nanoparticles, which are known as urea chitosan nanohybrid (CS-urea NH), and not only on the plant's response to this hybrid fertilizer. However, the mixtures of NPK synthetic fertilizers and CS NP hybridization were investigated for enhancing growth and productivity of wheat [28], cucumber; Cucumis sativus L. [29], and potato; Solanum tuberosum L. [30]. Until now, the application of urea chitosan nanoparticles in paddy fertilization practices has remained unexplored or limited.…”

Effect of Organic Nano-NPK Formulation on Fruit Yield and Quality in Banana Cv. Nendran (Musa AAB)

“…According to Jubeir and Ahmed (2019), using nano fertilizers and NPK enhances the vegetative and fruit characteristics of date palm. The greenhouse cucumber fertigated with 40% RDF as nano fertilizer recorded maximum number of pickings and number of fruits per vine accounting for maximum increase in marketable yield compared to water soluble fertilizers (Modi et al 2021). Benefits of nanoparticle application in fruit crops include fruit productivity, quality and shelf life through their positive effects on anatomical, morphological, physiological, physicochemical and molecular traits (Sharma et al 2021) The utilization of nanotechnology in fruit crops especially banana still remains unexplored.…”
