Abstract
An experiment was conducted to evaluate the influence of different organic manures on growth, yield, and quality of radish (Raphanus sativus) at Institute of Agriculture and Animal Science (IAAS), Rupandehi, Nepal. The experiment was laid in Randomized Complete Block Design single factorial with seven treatments and three replications. The treatments were consisted as farmyard manure (FYM) (30 tha-1), poultry manure (PM) (30 tha-1), FYM(15 tha-1) + PM (15 tha-1), FYM (15 tha-1) + vermin compost (2.5 tha-1) + phosphate solubilizing bacteria (PSB) (10kgha-1), FYM (15 tha-1) + bone meal (5 tha-1) + PSB ( 10 kgha-1), PM (15 tha-1) + vermi compost (2.5 tha-1) + PSB (10 kgha-1), PM (15 tha-1) + bone meal (5 tha-1) + PSB (10 kgha-1). A significant variation was observed among the treatments. The poultry manures combined with bone meal and PSB significantly increased the growth and yield attributes viz., plant height (43.43 cm), number of leaves (20.9), shoot length (44.49 cm), root length (21.68 cm), root diameter (3.77 cm), root weight (211.3 gm plant-1 ), shoot weight (170.9 gm plant-1), biological yield (82.28 gm plant-1), dry root weight (46.89 gm plant-1), dry shoot weight (50.33 gm plant-1), total dry weight (97.22 gm plant-1), root yield (49.31 tha-1), shoot yield (939.87 tha-1) and biological yield (89.19 tha-1) at 70 days after sowing. The vitamin-C in radish root was recorded highest (2.87 mgml-1) with PM. However, the total soluble solid remains unchanged among the treatments. In total, the results suggested that poultry manures combined with bone meal and PSB is suitable to cultivate radish.

Highlights
Radish (Raphanus sativus) is a winter season vegetable, grown throughout the country and occupies 16915.7 ha with total production of 268119.6 tones and productivity15.9 tha-1 (MoAD, 2017)
The results of this study revealed good response of radish to organic manures and their combination
They were significantly lower in T1, with values 4.58 tha-1, 1.91 tha-1, and 6.5 tha-1, respectively, which was at par with T4 (Table 5).The results are in conformity with the findings of Kumar et al (2014) in respect of fresh weight and dry weight recorded highest by applying poultry manure (PM) (50%) and Vermi compost (50%) in radish
Summary
Radish (Raphanus sativus) is a winter season vegetable, grown throughout the country and occupies 16915.7 ha with total production of 268119.6 tones and productivity15.9 tha-1 (MoAD, 2017). The global production of radish is estimated 7 Mt year-1, which is about 2 % of the total world vegetables production (Ghimire et al, 2018). The characteristic pungent flavor of radish is due to is othiocyanate (Kushwah, 2016) It is used for neurological headaches, chronic diarrhea, urinary complaints, sleeplessness, and piles (Singh and Bhandari, 2015). PM and FYM are commonly available, but their application alone is not competent to high energy demand (Henderson et al, 2016). These manures in combination with bone meal, PSB, and vermin compost were used. The study was conducted to assess the appropriate organic manures and their combination for optimum growth, yield, and quality of radish
