| dc.description.abstract | A field experiment was conducted during kharif 2011 to study the effect of fly ash on growth, physiological and biochemical traits and yield in groundnut [Arachis hypogaea (L.)] at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The experiment consisted of eleven treatments consisting different combinations of fly ash with inorganic fertilizers, FYM, Gypsum, Zn, Fe and Borax. The experiment was laid out in randomized complete block design with three replications. Growth and development parameters i.e., plant height, number of branches, leaf area and total dry matter were significantly highest with T7 (40 t of fly ash/ha along with Recommended dose of NPK (RD NPK) and 50% gypsum, Zn and Fe) at all growth stages. Chlorophyll content and nitrate reductase activity were also significantly higher with the application of T7 (40 t of fly ash/ha along with RD NPK and 50% gypsum, Zn and Fe) Among the different combination of Fly ash application T7 (40 t of fly ash/ha along with RD NPK and 50% gypsum, Zn and Fe) recorded significantly higher pods per plant (41.17), 100 kernel weight (43.26 g), shelling percentage (76.35%), yield per plant (18.74 g), higher pod yield (3617.4 kg ha-1) and harvest index (42.34 %) compared to other treatments. However, T7 was on par with T10 (RDNPK 40 t fly ash/ha + 25% RD gypsum +25% RD Zn + 25% RD Fe) followed by T6 (RDNPK 30 t fly ash/ha + 50% RD gypsum +50% RD Zn + 50% RD Fe). Similar trend was also recorded with oil content, germination per cent and seedling vigour index. Application of T7 (40 t of fly ash/ha along with RD NPK and 50% gypsum, Zn and Fe) recorded significantly higher oil content (51.17%), germination (90.5 %) and seedling vigour index (2212) compared to Bhoochetana (T11). It could be inferred from the study that fly ash @ 40 t/ha along with RD NPK and 50% gypsum, Zn and Fe can increase the yield in groundnut. | en_US |
