This study aims to determine the effect of biochar dosage and compost fertilizer and its interaction on the growth and yield of corn crops. This experiment used a randomized block design (RBD) with a factorial pattern consisting of 2 factors. The first factor was the dose of biochar (B) consisting of 4 levels, namely: 0 ton ha-1 (B0), 5 ton ha-1 (B1), 10 ton ha-1 (B2), 15 ton ha-1 (B3). The second factor is the dosage of compost fertilizer (K) consisting of 2 levels: 0 ton ha-1 (K0), and 20 ton ha-1 (K1). The results showed that the interaction between the treatment of biochar dose and compost fertilizer had no significant effect on all observed variables. Biochar and compost treatment have significant effect to most observed variables, except on leaf area and harvest index have no significant effect. Treatment of biochar with a dose of 10 ton ha-1 gave the highest dry kiln seedlings weight of 7.83 tons increased by 35.60% compared to the lowest dose without biochar of 5.77 tons. Treatment of compost doses of 20 ton ha-1 gave the highest dry seed oven per hectare weight of 7.42 tons increased by 16.60% when compared with the lowest yield on treatment without compost dose as much as 6.37 tons.

Two Systems

Maize (Zea mays L.) was grown outdoors hydroponically and in soil to compare yields in the two systems and to determine the extent to which soil temperature and plant nutrition limit yield of soil-grown plants. The hydroponic system consisted of 22.5-L plastic pails filled with "Turface" to which nutrient solution was added at least twice daily. In all 3 yr dry-matter accumulation throughout the growing season was greater on the hydroponic system than in well-fertilized, irrigated sandy-loam soil when planting pattern and density were the same. Maximum aboveground dry matter and grain dry matter on the hydroponic system were 25.8 and 12.2 Mg ha−1, respectively. It is apparent that there is a soil-based constraint that limits aboveground dry-matter production to 75–85% of the potential with the aboveground environment in the region. Grain yield appears to be limited to a lesser extent. To determine the effect of root-medium temperature, growth in pails buried in the soil was compared to that in soil and in pails placed on the soil surface. Although the temperature of the buried pails was consistently lower than that in the aboveground pails and in the soil, dry matter accumulation was similar to that in the aboveground pails indicating that soil temperature was not a cause of the lower yield of the soil-grown plants. There was no evidence that plants growing on the highly fertilized soil were nutrient limited at any growth stage. Other studies have indicated that transient water stress on soil-grown plants will not explain the difference in growth on the two systems.

   A biological experiment was carried out for the purpose of knowing the effect of the type of organic matter, source and level of phosphorous on the growth and yield of corn (Zea mays L.) in gypsum soil.  The experiment was carried out in one of the agricultural fields in Salah al-Din Governorate / Al-Alam district in the year 2019. The study included three factors (type of organic fertilizer, phosphorous source and phosphorous level).  The factor included the type of organic fertilizer (not adding Z, compost K and sheep waste S), while the second factor included the source of phosphate fertilizer (Triple super phosphate T, diammonium phosphate D), and the third factor included phosphorous levels (0, 90, 180 and 270) kg P ha-1.  The experiment was carried out in three replications according to a randomized complete block design (RCBD).  Sheep manure outperformed compost in all growth and yield traits, and diammonium phosphate fertilizer outperformed Triple le super phosphate, and the level (270) kg P ha-1 was superior to the rest of the addition levels in all growth and yield traits. The interaction between sheep manure and diammonium phosphate fertilizer at the level of addition (270) kg P ha-1 gave the highest average in the dry weight of the vegetative mass after 45 and 75 days of planting, it reached (55.50 and 130.81) gm plant-1, respectively, Chlorophyll content in leaves (52.80) SPAD and grain yield reached (8119) kg ha-1.

Existem poucas informações sobre a melhor época de semeadura de milho, durante o período da “segunda safra” no norte de Mato Grosso. O objetivo do trabalho foi verificar o comportamento produtivo de três híbridos de milho, semeados em seis épocas, durante a “segunda safra,” ou “safrinha”, no norte de Mato Grosso, Sinop-MT. O experimento foi conduzido em um Latossolo Vermelho Amarelo distrófico típico argiloso, entre janeiro e julho de 2014. O delineamento experimental foi em blocos ao acaso, com quatro repetições em esquema fatorial 3 x 6. Utilizou-se três híbridos comerciais simples e “precoces”: Maximus®; Truck (Syn7316)® e Status (Syn7205)®. As épocas de semeadura ocorreram aos 0, 7, 14, 21, 28 e 35 Dias após a semeadura de 26/01, correspondendo as datas de 26/01; 02/02; 09/02; 16/02; 23/02 e 02/03 de 2014, respectivamente. Avaliou-se a altura de plantas, área foliar, massa seca, teor relativo de água e produtividade da cultura. No florescimento, os menores teores de água nas folhas ocorreram nas plantas semeadas entre os dias 16/02 e 23/02. O crescimento vegetativo do milho foi o menor na época de semeadura entre os dias 09/02 a 23/02. Os híbridos Truck®, Máximus® e Status® não apresentaram diferença de produtividade e são mais produtivos quando semeados no final do período de segunda safra, entre os dias 16/02 a 02/03.Palavras-chave: Zea mays L, milho segunda safra, matéria seca, área foliar, teor relativo de água. MAIZE SEED TIMES IN THE NORTH REGION OF MATO GROSSO ABSTRACT:Were not sufficient information’s about the best time sowing of corn crop, during period of maize off-season in the north of Mato Grosso. The objective of this work was to verify the productive behavior of three maize hybrids, sown in six seasons, during the "second harvest," in the north of Mato Grosso, Sinop-MT. The experiment was conducted in a typical clayey dystrophic Yellow Red Latosol between January and July 2014. The experimental design was a randomized complete block design with four replicates in a 3 x 6 factorial scheme. Three commercial hybrids were used: Maximus®; Truck (Syn7316) ® and Status (Syn7205) ®. Sowing times occurred on day after sowing of date based of 01/26; respectively for datas: 01/26; 02/02; 09/02; 16/02; 23/02 and 02/03 of 2014. The variables analyzed the height of plants, stem diameter, leaf area, dry matter, relative water content and crop productivity were evaluated. At flowering, the lowest leaf water contents occurred in the plants sown between February 16 and February 23. The maize vegetative growth was the lowest in the sowing season between 09/02 to 23/02. The Hybrids Truck, Maxima and Status had a productivity difference and are more productive when sown at the end of the second crop period, between February 16 to March 2.Keywords: Zea mays L., maize off-season, dry matter, leaf area, relative water content. DOI:
