According to Strategy & Tactics, a magazine which wrote the article 'Rumania: Forgotten Axis', the Rumanian Army could rely on fair degrees of industrial output.

Rumania produced a crude if very servicable submachinegun, modified tank destroyers for use against the Soviets (refurbished Czech, Soviet, or Hungarian marks), a light anti-tank gun, and the Axis powers' only "true" indeigenously-produced fighter, the IAR, a remarkable achievment for a nation still based to a great degree on agriculture as opposed to service or industry.

Rumanian troops fought extremely well in the Crimea, siezing Odessa and investing regions such as the Caucasus or Black Sea with some excellent - if costly - ratings of success.

The magazine states specifically:

"It appears that no one on the Axis side intended Rumanian troops to do much fighting after the liberation of Bessarabia. Even as Soviet armies fell back in disarray, bitter resistance held the Germans desperate for help. And so the Armata Romania began an offensive "on the fly", while lacking the planning, training, or equipment for such operations. Despite massive casualties, the Rumanians captured Odessa and made possible the capture of Sevastopol and the Crimea, helped overrun the Ukraine and penetrated deep into the Caucasus. Without Rumanian aid, the Germans could not have penetrated nearly as far into the Soviet Union and their defeat would have come much sooner."

Rumanian divisions were well-equipped by the German standard at the war's start, support coming in the form of anti-tank company for all deployments of that size - many of which were designated as brigades yet equaled both Hungarian and Italian units of division size or larger. Germany held back on Rumania, admittadly, and many Generals later shifted blame to them.
