Abstract:

Plant nutrients play vital role on maize productivity. Nutrients not only from chemical fertilizers increases crop yield but also with organic fertilizers. To evaluate the efficacy of organic fertilizers, received from NICO ORGO Company India, an experiment was conducted at NMRP farmland at Hariyali-Tandi on the acidic soil during the year 2011 winter season. Different agro-organic–fertilizers along with other chemical fertilizers and manures were used in the experiment. The experiment was designed with RCBD and replicated three times. Manakamana-3 was the variety planted in the experiment in the month of September at a spacing of 75 cm × 25 cm at the plot size of 22.5 sq. m. and was harvested in second week of February, 2012. Maize growth and yield parameters were taken into the study. The results showed significant effect of Organic-Fertilizers in plant height, stover and grain yield production. The highest grain weight (2.94 t ha-1) was recorded when the crop was supplied with 120: 60: 40 kg N, P2O5 and K2O ha-1 followed by Orgo Blend fertilizers at 617.5 kg ha-1 which was almost 121 % higher than those produced by non-treated crops. It seems that the highest net return of Rs 29,233.0 could be obtained when the crop is supplied only with NPK fertilizers (120: 60: 40 kg ha-1) followed by the crop supplied with Orgo Neem at 150 kg ha-1 which gave the net return of Rs 27555.0 ha-1.This paper discuss and highlights the results of Organic-fertilizer application on maize productivity in detail.
