Description M. Sc. (Ag.) Thesis, Agronomy
The present investigation entitled “Effect of integrated nutrient management on growth and yield of wetland rice (Oryza sativa L.)” was conducted at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India during rainy (Kharif) season of 2012 with a view to test the comparative performance of different NPK management treatments viz. Control, 100% RDF (120-60-60 kg ha-1) , 50% RDF + 25 % RDN as FYM , 50% RDF + 50 % RDN as FYM, 75% RDF + 25 % RDN as FYM and three levels of bioinoculants i.e. azospirillum , BGA and combined use of azospirillum + BGA. The factorial experiment was laid out in Randomized Complete Block Design with five NPK management practices and three levels of bioinoculants replicated thrice consisting a total of 15 treatment combinations. Various observations were recorded during the course of investigation including growth characters, yields attributes and yield as affected by NPK management and bioinoculants. Growth parameters were recorded at various phenological stages starting from 30 DAT followed by 60, 90 DAT and at harvest which included plant height, number of tillers hill-1, dry matter accumulation hill-1 and leaf area index (LAI). Similarly number of yield attributes like panicle length, grains panicle-1, panicle weight, test weight, grain and straw yield were also noted to assess the effect of treatments. On the basis of the above results the following conclusions may be drawn. Rice variety HUBR-2-1 responded favorably to the NPK application @ 75% RDF + 25% RDN as FYM for achieving higher yield in Varanasi region. The combined application of azospirillum + BGA is most suitable for increasing rice productivity. The integration of moderate NPK 75% RDF + 25% RDN as FYM with azospirillum + BGA proved most remunerative.
