Abstract

SummaryA nutritional experiment under glass used the tomato cv Moneymaker grown in pots of peat compost. The nutrient levels applied were: N (N150, N2100 g N m−2), P (P121.8, P243.6 g P m−2) and K (K183, K2166 g K m−2). The high N level increased flower number, fruit and seed yields and gave early flowering and ripening. The high P level increased seed yield. P2K2 and P1K1 led to earlier flowering than P1K2, and the percentage of fruit setting was higher in P1K2 than P1K1. The 100-seed weight was highest for trusses (T) 1 and 5 than for the other trusses. N2P2K2T1 gave the highest and N1P1K2T4 and N1P1K2T3 the lowest 100-seed weights. When the seeds from plants of the various treatments were sown, N2 seeds emerged earlier than N1 seeds. The results show that the most favourable combination for high fruit and seed yield, percentage of fruit setting and a higher seed weight was N2P2K2.
