Abstract:
A field experiment was conducted to evaluate the growth, yield, nutrient uptake and economics of wheat (Triticum aestivum L.) in rice – wheat cropping system under the combined use of soluble fertilizer and sea weed extract with the recommended dose of N, P and K and 75% dose of NPK at KVK Farm of Haidergarh, Barabanki (U.P.) during 2019-20 and 2020-21 in collaboration of IFFCO. Soluble NPK and sea weed extract (Sagarika) turned into provided through IFFCO. Application of recommended dose of NPK (RDF) with three spray of soluble fertilizer NPK @ 1.5% + sea weed extract @ 2. Five ml/litre of water + seed remedy with VAM (vesicular arbuscular mycorrhiza) at par with one hundred% of advocated dose + 3 spray of soluble NPK @ 1.5% and a hundred% of Recommended dose + three spray of soluble NPK @ 1. Five% + tank combined extract of sea weed @ 2.5 ml/litre of water recorded highest fertile tillers, no of grain, take a look at weight, grain and straw yield over rest of the treatment examined. Application of 75% NPK of advocated dose with three spray of soluble NPK tank mixed with sea weed extract + seed treatment with VAM at par with by using 75% of endorsed dose + 3 spray of soluble NPK @ 1.5% tank blended with extract of sea weed@ 2.5 ml/litre of water recorded significantly higher grain and straw yield than software of encouraged dose of NPK failed to produce equal yield to application of 100% recommended dose of NPK. Application of VAM in combination of soluble fertilizer at 75% RDF increased the yield by 10.8% while combined use of VAM and sea weed extract increased the grain yield 24.3% over combination of soluble fertilizer at 75% RDF. Application of sea weed extract in combination of soluble fertilizer at 75% RDF registered 17.4% higher yield over combination of soluble fertilizer at 75% RDF. Highest net return (Rs. 75279) and B: C ratio (2.57) recorded with recommended dose of NPK (RDF) + 3 spray of soluble fertilizer N P K @ 1.5% + sea weed extract @ 2.5 ml/litre of water + seed treatment with VAM followed by 100% of Recommended dose + three spray of soluble NPK @ 1.5% +VAM and a hundred% of Recommended dose + 3 spray of soluble NPK @ 1. Five% + sea weed extract.
