Abstract
The present field investigation entitled “Growth, Yield and Quality of Broad bean (Viciafaba L.) as influenced by nutrient management under different dates of sowing” was carried out at Vegetable Experimental Farm in the division of Vegetable Science and Floriculture, SKUAST-J, Chatha during rabi season 2018-2019. The experiment comprised of three levels of inorganic fertilizers i.e. 50%, 75%, 100% of recommended dose (50:60:50 kg ha-1 NPK) combined with two organic sources of plant nutrients (FYM and Vermicompost) under different dates of sowing (2nd fortnight of October and 1st fortnight November). The experiment comprised of 12 treatments laid out in a Randomized Block Design with three replications. Observation were recorded for 12 treatments viz. Plant height (cm), No. of branches plant-1, No. of nodes stem-1, Days to 50% flowering, Days to 50% pod setting, Pod length (cm), Pod width (cm), No. of pods plant-1, Pod weight plant-1 (g), No. of seeds pod-1, 100 seed weight (g), Pod yield (q ha-1), Protein (%) and TSS (°B). The result revealed that vegetative growth and yield parameters were significantly influenced by the application of different sources of nutrients under different dates of sowing. Application of 75% N through inorganic fertilizers in combination with 25% through vermicompost sown at 2nd fortnight of October yielded maximum number of pods plant-1 (78.33), pod weight plant-1 (95.07 g), plant height (156.27 cm), pod length (5.69cm), pod width (0.88cm), number of branches plant-1(10.27), number of nodes stem-1 (19.00), Pod yield (149.47 q ha-1) whereas, days to 50% flowering, days to 50% pod setting, 100 seed weight (g), number of seeds pod-1 were found non-significant in different treatments combination under different sowing dates. Total soluble solids (10.27°B) and protein content (30.79%) were highest in treatment combination of 75% N through inorganic fertilizers + 25% through vermicompost. Economically maximum cost benefit ratio (3.96) was recorded in treatment having 75% N through inorganic fertilizers + 25% through vermicompost sown during 2nd fortnight of October as compared to other treatments. Thus, replacement of 25% of chemical fertilizers with vermicompost suggested for getting higher returns in October sown broad beans.
