Production and physiological quality of onion seeds as a function of organo-mineral fertilization management

Abstract

In this work, the management of organo-mineral fertilization in the production and physiological
quality of onion seeds cv. BRS 367 (Riva). The treatments consisted of doses of organic
compound (CO) combined with Yoorin MasterÒ (YM) in the base and doses of Bokashi (BK) in
the cover: T1) base = 2 kg CO per m2 + 100g YM per m2 and 50g BK , Per bulb, on the cover;
T2) 2 kg C.O + 100 g Y.M and 100 g BK; T3) 4 kg C.O + 200 g Y.M and 50 g BK; T4) 4 kg C.O
+ 200 g Y.M and 100 g BK. The number of umbelas.parcela-1, mass of 1000 seeds and yield
of seeds were determined.area-1. Seed quality was evaluated by germination, first counting,
accelerated aging and seedling emergence tests under greenhouse conditions. The dose:
base fertilization with 2 kg of organic compound per meter2 + 100g of Yoorin Master and 50g
of Bokashi, per bulb, yielded a higher seed yield (377 Kg.ha-1). The different doses of organo-
mineral fertilizer did not influence the physiological quality of the seeds, with results above
95% in the first count and 99% in germination, accelerated aging and seedling emergence.
