Nutrient management in wheat (Triticum aestivum L.) under partially reclaimed coastal salt affected soil of south Gujarat

An experiment was conducted at Coastal soil salinity research station, Navsari Agricultural University, Danti during rabi seasons of 2016-17 and 2017-18 to study the effect of different levels of fertilizer on yield and nutrient uptake of wheat under partially reclaimed coastal salt affected soil of South Gujarat. The pooled results revealed that organic manures and fertilizer levels treatments influenced significantly the plant population at harvest, yield attributes, yield and economics of wheat crop. Application of FYM @ 10 t ha-1and higher dose of fertilizer i.e.120% RDF (216-108-00 kg NPK ha-1 ) treatment recorded significantly higher values of the growth parameters like plant height at 60 DAS (47.2 and 47.3cm), at harvest (87.3 and 87.4 cm), total tillers m-1 (110.3 and 110.9 cm), yield attributes like effective tillers (105.2 and 106.2 cm), spike length (8.5 and 8.8 cm) , spikelets spike-1 (12.8 and 13.4 ) grains spike-1 (29.2 and 29.1) etc., grain yield (3931 and 3896 kg ha-1 ) and straw yield (5246 and 5323 kg ha-1 ) of wheat crop. The net returns ha-1 (Rs. 51569 and Rs. 51468) and BCR (2.28 and 2.29) were maximum under FYM @ 10 t ha-1 and 120% RDF treatments, respectively. | Nutrient management in wheat (Triticum aestivum L.) under partially reclaimed coastal salt affected soil of south Gujarat
