Zusammenfassung:Field experiment was conducted during rabi season of 2009-10 and 2010-11, to study the effect of application of different sources organic manure and micro-nutrients on growth, productivity and quality of potato (Solanumtuberosum L.) grown under alluvial soil. The different sources of organic and micronutrients were integrated into 8 possible treatments viz. RDF (NPK @ 200 :150 :150 kg ha-1) , 50% of RDF + well decomposed FYM @ 10t ha-1, 50% of RDF + Well powder neemcake @ 0.5t ha-1,RDF+ Zinc sulphate @ 20kg ha-1as soil application, RDF + ammonium molybdate @ 1kg ha-1as soil application, RDF + sodium tetraborate @ 1kg ha-1as soil application, RDF + tuber soaking with 40g inc sulphate + 10g ammonium molybdate + 10g sodium tetraborate, RDF + foliar spray of 1% KnO3 salt. All the treatments resulted in improvement of growth and tuber yield characteristics, out of these treatments where organic sources of nutrient were integrated registered significantly maximum effect. Highest leaf area index, leaf area duration, dry matter production, tuber bulking rate and tuber yield in potato were recorded in the treatment 50% recommended dose of NPK + 10t FYM ha-1, while the lowest was observed in 100 % inorganic fertilizer treatment (RDF). Organic treatment were also in favour of producing medium and large size tuber, whereas, micronutrient were in favour of producing extra large size tuber. Highest value of starch and reducing sugar content were also recorded under the treatment where the crop received organic manure.
