“…These links are more stronger the smaller plant living spaces are. Currently, the most common methods of sowing of the proso millet are common gutter, row, and band sowing; narrow-row and cross sowing are used much less (Iqbal et al, 2013;Mesquita and Pinto 2000;Nelson, 1977). Sowing rates of the proso millet greatly vary in the major areas of its cultivation (from 10 to 45 kg/ha or from 1.2 to 8.0 million viable seeds per hectare (Yakuta, 2013;Belogurova, 2001).…”

The aim of the research is to define optimal sowing parameters that ensure the highest yielding capacity and high quality of the proso millet seeds (Panicum miliaceum L.). To achieve a stated goal we established and analyzed multiple-factor interrelations of the formation of highly productive seed sowing of the proso millet by improving sowing methods and sowing rates as well as conditions improving sowing qualities and yielding capacity of seeds with the application of correlation pleiades. We founded that deviation from the recommended sowing rates in production results in the decline of yielding capacity level. We also suggested that the deficit of seed material caused the highest shortfalls in seed yields compared to its over-expenditure; moreover, the seed planted with wide row spacing had the best yielding capacity, while sowing with row spacing of 15 cm and sowing rate at 3.5 million seeds/ha provided the its highest yielding capacity.

Two field experiments were conducted in the experimental station farm, faculty of agriculture, Ain Shams University at Shalakan, Kalubia Governorate, during the two growing seasons, i.e. 2009 and 2010, to investigate the response of growth and forage yield production of pearl millet cv. Shandaweel 1 to nitrogen fertilization rates and cutting height above the soil surface. Four nitrogen rates as ammonium nitrate (33.5%N), 0, 30, 45, and 60 kg N/fed, were arranged in the main plots and two levels of cutting heights (10 and 20 cm above the soil surface) in the subplot with four replicates in split-plot design. In the second season, nitrogen application increased up to 75 kg N/fed. The main results were as follows: Significant increases were appeared in plant height (cm), number of tillers/m 2 , number of leaves/m 2 , and leaf area index during the two growing seasons as nitrogen fertilization rates increased except at the third cut in the first season for plant height (cm) and number of tillers/m 2 , the first and second cuts of the first season for number of leaves/m 2 and at the third cut during the first season of study for leaf area index, while leaf/stem ratio was not affected significantly during the two growing seasons. Green forage yield/fed was significantly increased as nitrogen application rates increased during the two growing seasons except at the third cut of the first season of study. Increasing nitrogen fertilization rates up to 75 kg N/fed caused significant increases in dry forage yield during the three collected cuts in the second season of study and the second cut during the first season of study as well as in the combined results. Plant height (cm) was significantly affected as cutting height above the soil surface increased in the second cut (2009) and the first cut (2010) where plant height increased at 10 cm as cutting height than at 20 cm above the soil surface. Significant differences were appeared in number of tillers/m 2 as cutting height varied from 10 to 20 cm in the two studied seasons. The highest cut of number of tillers/m 2 was scored at 20 cm cutting height than those at 10 cm in the second and third cuts during the two growing seasons. A number of leaves/m 2 as well as leaf area index were influenced significantly as cutting height increased during the two growing seasons except in the second and third cuts during 2009 or the third cut during 2010 for number of leaves/m 2 and in the second cut of the first season (2009) and the third cut during 2010 for leaf area index. Significant effects were noticed in leaf/stem ratio as cutting height differed in the second or third cut in 2009 and in the three collected cuts in combined analysis. Green forage yield, dry forage yield/feddan increase significantly as cutting height differed during the two growing seasons as well as the combined results except in the first cut during the first season of study for dry forage yield. Green forage yield as well as dry forage yield was significantly affected by the interaction between nitrogen ferti...

O experimento foi conduzido na Estação Experimental Agronômica/UFRGS, (30º05'52"S; 51º40'08"W) com o objetivo de avaliar o efeito da irrigação (irrigado e não irrigado), de duas épocas de remoção da forragem (E1- remoção de aproximadamente 50% dos ápices dos meristemas apicais dos perfilhos primários e E2- remoção de 75%) e de quatro doses de nitrogênio (0, 50, 100 e 150kg.ha-1), sobre os componentes de rendimento e o rendimento de sementes de milheto (Pennisetum americanum (L.) Leeke). O delineamento experimental utilizado foi parcela sub-subdividida com quatro repetições. A semeadura foi realizada com máquina de plantio direto no dia 29/12/00. As doses de N foram parceladas em duas aplicações iguais, sendo a primeira em 16/01/01 e a segunda uma semana após os cortes em E1 e E2. Os cortes foram realizados a uma altura de 20cm (E1=09/02 e E2=19/02) e a colheita de sementes nos dias 30/04 e 01/05. A aplicação de doses de N teve influência sobre os componentes de rendimento, tais como, número de panículas.m-2, número de panículas com sementes.m-2, comprimento de panícula, peso de panícula e número de sementes.panícula-1. O componente panículas com sementes respondeu ao efeito das interações entre irrigação com doses de nitrogênio e épocas de corte com doses de nitrogênio. Maiores pesos de panícula e de mil sementes foram registrados no corte precoce (E1). O rendimento de sementes puras viáveis foi influenciado pelas épocas de corte e doses de nitrogênio, e no ponto de maior eficiência técnica do N (120kg.ha-1), foi de 769kg.ha-1. Os componentes do rendimento que mais se correlacionaram com o rendimento de sementes foram o número de sementes.panícula-1 e o peso de mil sementes. O rendimento de matéria seca total respondeu às doses de N, sendo expresso por uma regressão linear positiva. A irrigação não afetou a resposta das variáveis estudadas.
