Effect of Foliar Sprays on Seed Yield and Economics of Niger [Guizotia abyssinica (L.f.) Cass]

Abstract

Field experiments were conducted on niger cv.GA.10 (Deomali) in red sandy to clay loam soils of RRTTS, Semiliguda, Koraput (Odisha) during kharif seasons of 2008, 2009 & 2010 to find out suitable combination of soil and foliar application of nutrients (urea and di-ammonium phosphate) for maximizing growth and seed yield. Nine treatments consisting with different nutrient management were tested in randomized block design with three replications. The results revealed that, foliar applications of Urea and DAP gave better performance regarding growth and yield attributes. Highest seed yield (417.2 kg/ha), net monetary return (Rs. 4247.00/ha) and benefit-cost ratio (1.51), recorded with application of 100% RDF + foliar application of 2% Urea twice at flowering and capitula formation stage (T 4 ) followed by T 5 (RDF + foliar spraying of 2% DAP twice at flowering and capitula formation stage) i.e. seed yield 387.7 kg/ha, net monetary return Rs. 3277.00/ha and benefit-cost ratio 1.39.

Growth analysis in groundnut (Arachis hypogea L.) as influenced by Foliar nutrition

“…Hence, it reduces the flower drop and ultimately enhances pegging and pod development. These results are in conformity with the findings of Shashikumar et al (2013) and Dalei et al (2014).…”

“…Therefore, better availability and uptake of nutrients could be assigned as the proper reason behind the significant increase in dry matter production and its accumulation in foliar spray treatments. The similar observations were made by Shivakumar Malladada (2005) and Dalei et al (2014).…”

Effect of Water Soluble Fertilizers on Yield, Oil Content and Economics of Groundnut

“…Therefore, better availability and uptake of nutrients could be assigned as the proper reason behind the significant increase in dry matter production and its accumulation ultimately reflected in yield parameters. Similar results were reported by Shivakumar [22] and Dalei [23]. Sulphur uptake was positively correlated with oil yield (0.96 **).…”

Effect of plant growth regulators and fertilizer spray on growth and yield of Niger[Guizotia abyssinica (L.f.) Cass]

“…Foliar application of Urea and DAP gave better performance regarding growth and yield attributes (Dalei et. al 2014) [2] . Foliar application of 19:19:19 results in increase in the yield (Gutte et al, 2018) [3] .…”
