Influence of selective combination of city compost and NPK fertilization on growth and yield of spinach (Spinacia oleracea L.)

The present investigation was carried out at Dr. B.R. Ambedkar University of Social Sciences, Mhow, Madhya Pradesh to find out the effects of city compost on growth and yield of spinach during 2018-19. Spinach cv. All Green was used for the experiment with of different doses (5, 10, 15 and 20 t/ha) of city compost along with recommended dose of NPK fertilizers (100:60:60 kg NPK/ha). Maximum growth parameters (germination percentage, plant height, leaf length, leaf width and petiole length) were recorded with city compost @ 10 t/ha + 50% of RDF (T4) followed by city compost @ 15 t/ha + 25% of RDF (T5). Whereas, the maximum average number of leave per plant and yield were recorded under city compost @ 10 t/ha + 50 % of RDF followed by city compost @ 15 t/ha + 25 % of RDF. This treatment has also registered the superior from economic point of view. Furthermore, the minimum values of growth and yield were recorded under control. | Influence of selective combination of city compost and NPK fertilization on growth and yield of spinach (Spinacia oleracea L.)
