Abstract

A field experiment was conducted to determine the effects of irrigation frequencies and mulching materials on the growth and yield of radish (Raphanus sativus) variety ‘Beeralu rabu’. This experiment was carried out in a factorial Randomized Complete Block Design with eight treatments, which included combinations of irrigation frequencies [3 days irrigation intervals (3 DIL), 5 days irrigation interval (5 DIL)] and organic mulching materials (no mulch, paddy straw, shredded wood and coir fibre). Each treatment was replicated six times. The tested treatments were applied after 12 days of seed sowing. The number of leaves, leaf area, leaf fresh and dry weights, tuber length, tuber girth and fresh and dry weight of tuber were measured at harvest to assess the growth of the crop and the yield. The results revealed that 3 days irrigation interval performed well for most of the parameters except the mean number of leaves and tuber girth at 5 days irrigation interval. In the overall performance of mulch, coir mulch showed maximum performance in all parameters while shredded wood mulch showed second higher growth and yield parameters of the crop. In the present study, all mulching materials used are waste materials, which could be obtained for free or at a very low cost. Hence, the mulching practice is better to be adopted by the farmer as it enhances the growth and yield of radish, by conserving the soil moisture and suppressing the weeds in the field.
