Effect Of Different Organic Manures On The Growth And Yield Of Radish (Raphanus Sativus L.) In Parbat District

In Nepal, radish (Raphanus sativus) is a popular root vegetable. Because of the careless and ongoing use of chemical fertilizers, which deteriorate the quality of the soil, its productivity is decreased. Therefore, from October to November of 2021, an experiment was conducted in Kushma, Parbat to determine the proper ratio of organic manure to preserve and improve the quality of the soil. Design used was randomized complete block design with seven treatments that is farmyard manure 30 t ha -1, farmyard manure 20 t ha-1+ mustard oil cake 2 t ha-1, poultry manure 20 t ha-1, poultry manure 15 t ha-1 + mustard oil cake 2 t ha-1, farmyard manure 15 t ha-1 + poultry manure 10 t ha-1, farmyard manure 15 t ha-1 + poultry manure 10 t ha-1 + mustard oil cake 2 t ha-1 and control with three replications each. Line sowing of forty days variety was done with the spacing of 20cm × 20 cm. There were 30 plants per plot among them 5 sample plants were taken randomly. These treatments had varying effects on the various growth and yield-related indicators. Plant height (44.87 cm), number of leaves (24.40), root length (28.58 cm), root diameter (3.2 cm), root yield (21.84 t ha-1), shoot yield (29.86 t ha-1), total biological yield (51.70 t ha-1), dry root weight (31.70 g), dry shoot weight (35.45 g), and total dry matter (66.15 g) were all significantly increased by the combined application of mustard oil cake, farmyard manure, and poultry manures. The control treatment yielded the lowest results. These findings suggested that the addition of organic manures had a favorable impact on the majority of growth and yieldrelated factors, including radish yield.
