Abstract


ABSTRACT

Ecological aspects of organic fertilizer use are more important and concerned than only production benefits. To study the effect of different fertilizer sources on growth, yield and ecological parameters of broccoli under the climatic condition of chitwan, a research was conducted at Agriculture and Forestry University from Sep, 2015 to Feb, 2016. Calabrese variety of broccoli was used with ten treatments viz; recommended chemical fertilizer (380:180:80 kg NPK ha-1), Farm Yard Manure (FYM), Vermi-compost (VC), Cow urine (CU), Bio organic fertilizer (BOF), (NPK 50%+FYM 50%), (FYM 50%+CU 50%),(FYM 50%+VC 50%),(FYM 50%+BOF 50%) and {25% (FYM+VC+CU+BOF)} in RCBD replicated three times with spacing of 60×45cm2 and plot size of 5.4m2. The study revealed that the curd yield (10.63tha-1), stem diameter (25.72mm), dry matter production (6.34tha-1) and leaf area index (5.12) were observed highest at recommended NPK treatment. Likewise, no. of leaf production per plant was highest at (NPK 50%+FYM 50%) combination treatment. Among the organic treatments, (FYM 50%+cow urine 50%) combination showed highest curd yield (7.79tha-1), stem diameter (24.63mm), dry matter production (5.49tha-1) and leaf area index (4.95). The highest C: N ratio (12.38:1) was observed in the {25% (FYM+VC+CU+BOF)} combination whereas lowest C: N ratio was recorded in recommended NPK (9.96:1). Likewise, highest soil organic matter (SOM) content (2.85 %) was found at (FYM 50%+ VC 50%) treatment and lower SOM (2.06%) was recorded in NPK applied treatment. Thus, the result showed that chemical fertilizer (NPK) produced higher yield in first season but the ecological benefits of these fertilizers are relatively less than other organic fertilizers.
