In the subtropical semi-arid zones, sorghum Sorghum bicolor (L.) productivity is limited by numerous constraints. Relatively few studies have been conducted to measure the response of grain sorghum varieties to tillage and nitrogen. For sustainable crop production, selected tillage practice and fertilizer application are important. Field experiments were conducted at Al Qurna (QL), 74 km northwest Basrah province and Shatt al-Arab (SHL) and 17 km east Basrah province. A randomized complete block design, arranged in a split-split plot, was used with three replications. The tillage system was no tillage (NT), reduced tillage (RT), and conventional tillage (CT), while sorghum varieties were Inqadh, Rabih, and Cavire 2, and four levels of N fertilizer, viz., 0, 40, 80, and 120 kg ha−1. The objective of research was to evaluate two sorghum (Sorghum bicolor L.) varieties to tillage system and nitrogen (N) fertilizer. The application of tillage was shown to enhance the growth of sorghum as observed in the plant height, leaf area, number of grains panicle−1, 1000-grain weight, yield, biomass yield, and root dry matter. CT surpassed the other treatments for all studied traits. The highest value of plant height, number of grains panicle−1, grain yield, biomass yield, and root dry matter in the QL and SHL locations, respectively, were produced by Cavire 2. The plots fertilized with 120 kg N ha−1 maximize the values of plant height (132.33 cm in the SHL location), leaf area (3040.53 and 2751.47 cm2 in the QL and SHL location respectively), number of grains panicle−1 (1431.37 in the SHL location), 1000-grain weight (31.77 g in the QL location), biomass yield (15752.00 kg ha−1 in the SHL location), and root dry matter (22.42 and 20.75 g root cm−3 in the QL and SHL locations, respectively). Cavire 2 variety under CT with 80 kg N ha−1 in the QL location was the best (observed as the most promising) in terms of grain yield. Whereas Cavire 2 under CT showed best performance with 120 kg N ha−1 in the QL location in terms of biomass yield character.

RESUMO – Com o objetivo de determinar o acúmulo de massa seca e macronutrientes ao longo do ciclo do sorgosacarino BRS 506, em diferentes níveis de adubação NPK, foram instalados experimentos por dois anos, em Latossolo,sob irrigação. Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições. Os tratamentosforam de quatro níveis tecnológicos, relacionados à adubação N-P2O5-K2O, em kg ha-1: muito baixo (NPK = 0-0-0);baixo (NPK = 80-50-80); médio (NPK = 160-100-160) e alto (NPK = 240-150-240). Avaliaram-se o acúmulo demassa seca e macronutrientes aos 30, 50, 70, 90 e 110 dias após plantio (DAP). No geral, foram ajustados modelospolinomiais de segundo grau. O acúmulo de massa seca e macronutrientes apresentou taxa inicial baixa, até cerca de30 DAP, e a partir daí aumentou consideravelmente, até próximo à maturação, para então se estabilizar e decrescer.No geral, o acúmulo de massa seca foi maior no nível tecnológico alto e o acúmulo de nutrientes não diferiu entre osníveis médio e alto, sendo menor para os níveis baixo e muito baixo. Recomendam-se 160-100-160 kg ha-1 de N-P2O5-K2O para produtividade satisfatória do sorgo sacarino e manutenção da fertilidade do solo, além de outras práticas quefavoreçam a ciclagem de nutrientes.Palavras-chave: Sorghum bicolor (L.)

The treatments comprised fourlevels of soil fertility, related to N-P2O5K2O fertilization, in kg ha-1: very low (NPK = 0-0-0); low (NPK = 80-50-80);medium (NPK = 160-100-160) and high (NPK = 240-150-240). Dry matter accumulation and macronutrients wereevaluated at 30, 50, 70, 90 and 110 days after planting (DAP). In general, polynomial models of the second degree wereadjusted. Dry matter and macronutrient accumulation presented a low initial rate, until 30 DAP, from there it increasedconsiderably until near the maturation, then stabilizing and decreasing. In general, dry mass accumulation was higherat high technological level and nutrient accumulation did not differ between medium and high levels, being lower forlow and very low levels. It is recommended to apply 160-100-160 kg ha-1 of N-P2O5-K2O for a satisfactory productivityof sorghum and maintenance of soil fertility, in addition to other practices favoring the nutrients cycling.Keywords: Sorghum bicolor (L.)
