Abstract
The main objectives of the experiment were to evaluate the effect of DAP and nano-DAP along with basal fertilizers on growth and yield of upland rice. The study was conducted in randomized block design with three replications. The experiment was carried out at Instructional Farm, College of Agriculture, Vellayani, Kerala during November 2022 to February 2023. The study consisted of (4×2)+1 treatments with two factors. The first factor was levels of recommended dose of nutrients (N) with four levels (n1 : 100 per cent N and P; n2 : 75 per cent N and P; n3 : 50 per cent N and P; n4 : 25 per cent N and P). Second factor was foliar fertilizers (F), included two levels (f1 : 2 per cent DAP at AT and PI stage; f2 : 0.2 per cent nano-DAP at AT and PI stage). Plant height, tillers per square metre, leaf area per hill, leaf area index, flag leaf area per hill and total dry matter production were significantly higher in full recommended dose of nutrients. Leaf area per hill, leaf area index, leaf area duration and flag leaf area per hill were higher with DAP treatment. Higher value of leaf area per hill, leaf area index, leaf area duration, flag leaf area per hill, total dry matter production, grain and straw yield were recorded in full dose of fertilizer along with DAP treatment. Considering the growth attributing factors and yield, the application of 100 per cent N and P along with 2 per cent DAP application was the best treatment combination.
