Abstract

Brazil is the largest producer of passion fruit, having the Northeast region as the main producing region, where orchards are formed almost exclusively from seed. This work aimed to evaluate the influence of different qualities of water and four levels of liquid manure applied to the soil in the absence and presence of mineral NPK fertiliser on the physiological attributes of yellow passion fruit seeds. The seeds were produced in a field experiment conducted in Jacana county, Rio Grande do Norte State-Brazil and seed quality was assessed in the Laboratory of Seed Analysis (LSA) from Agrarian Sciences Centre of Federal University of Paraiba in Areia County, Paraiba State, Brazil. In the laboratory, the experimental design was completely randomised with 16 treatments in four repetitions. The bovine biofertiliser inhibited the seed quality obtained for plants irrigated with non-saline water, but increased the viability of seeds in plants irrigated with saline water. Characteristics evaluated were the first count of normal seedlings, and speed index germination (SIG, dry matter weight of roots and shoot). The mineral fertilisation of the soil with NPK increased the seed viabilityin plants irrigated with both non-saline and saline waters. Key words: Passiflora edulis, salinity, organic fertilization, mineral fertilisation, seed production.

The yellow passion fruit (Passiflora edulis) is a tropical fruit that has had a cultivation area which has enhanced quickly in recent years and has occupied a prominent place in tropical fruit production (Meletti, 2011).In 2013, the national production was of 420 tons, despite the occurrence of virus and successive droughts in the Northeast, which is the largest producer of the fruit (Fruitgrowing Brazilian Yearbook, 2014).Most commercial orchards of passion fruit are comprised of seedlings obtained from seeds
The objective of this work was to evaluate the physiological attributes of yellow passion fruit seeds produced from plants irrigated with saline and not saline water, with and without the liquid biofertiliser applied to the soil, in the presence and absence of mineral fertilisation with NPK

Summary

INTRODUCTION

The yellow passion fruit (Passiflora edulis) is a tropical fruit that has had a cultivation area which has enhanced quickly in recent years and has occupied a prominent place in tropical fruit production (Meletti, 2011). The production and physiological seed quality are influenced by the availability of nutrients to plants, by affecting the formation of the embryo and reserve organs, as well as the chemical composition and, metabolism and force (Carvalho and Nakagawa, 2000) This influence was observed in other agricultural crops, such as corn (Bono et al, 2008) and millet (Abrantes et al, 2010), subject to nitrogen fertilisation. The objective of this work was to evaluate the physiological attributes of yellow passion fruit seeds produced from plants irrigated with saline and not saline water, with and without the liquid biofertiliser applied to the soil, in the presence and absence of mineral fertilisation with NPK
