The western tarnished plant bug, Lygus hesperus Knight (Hemiptera: Miridae), is an important insect pest of lettuce, Lactuca sativa L. in the central coast region of California. However, little is documented on the injury symptoms relative to levels of L. hesperus infestation on lettuce. Experiments were conducted in which lettuce plants were exposed to 0, 1, 3, 5, and 10 L. hesperus adults for 2 and 7 days. The major injury symptom observed was lesions on the midrib of the leaves, and under low to moderate infestation (e.g., one to five adults per plant) after 2 days of exposure these lesions were not significantly different from the insect-free control. Under heavy infestation (e.g., 10 adults per plant), however, lesions developed rather quickly after 2 days of exposure. The number of lesions was positively associated with numbers of feeding sites and eggs. When heavy infestation lasted for a week, most of the plants died. At low to moderate infestation, more lesions developed compared with the insect-free control. After a weeklong exposure, an increase in number of lesions was negatively associated with plant height. The results emphasize the need for regular scouting to facilitate immediate management decisions and actions to reduce losses from L. hesperus feeding and oviposition injury in lettuce.

Lettuce vegetables (Lactuca sativa L.) much needed by the community to meet the nutritional needs, but lettuce production is still low because of low productivity. Increasing the quality and quantity of vegetables grown on polybags is by fertilizing and arranging the composition of the planting medium. Provision of fertilizer aims to increase the supply of nutrients needed plants to boost the production and quality of crops. Fertilizer is to provide or add nutrients that plants need. However, fertilizer will tend to cause high production value and less appropriate with vegetable planting at home, therefore more optimized setting the composition of planting media. Planting media should be able to provide nutrients needed by plants. Farmers use plant residual organic materials such as rice husk as and cockpit for vegetable cultivation. The rice husk is the outermost part of the grain. The rice husk ash usually contains N 0.32%, P 0.15%, K 0.31%, Ca 0.96%, Fe 180 ppm, Mn 80.4 ppm Zn 14.10 ppm and pH 6, 8 which is expected to meet the needs of plant nutrients. The study was prepared using a complete randomized design with one factor that is the addition of planting media in the form of rice husk ash with the proportion of top soil and rice husk ash as follows: M1 (3: 1), M2 (2: 2), and M3 (1: 3). The observed variables were stem height, crown dry weight, and root dry weight. Data analysis used F Test 5% and continued with Duncan Multiple Range Test (DMRT) 5%. The results obtained at plant height of M3 (1: 3) gave the best result where there was a plant height increase of 40 cm from the first day of planting until the third day, the addition of rice husk ash did not affect the addition of root dry weight and dry weight of crown.

The experiment was conducted under field condition at Jimma University College of Agricultures and Veterinary Medicine (JUCAVM) to determine the Effects of Different Rate of Organic and Inorganic Fertilizer on Growth and yield Components of Potato (Solanum tuberosumL).The experiment design used was randomized complete block design(RCBD). The experimental treatments were replicated three times. A Potato cultivar ‘Jalene’ was grown combined with Farmyard manure and nitrogen (F0N0), (F20N70), (F0N35),(F0N70), (F20N35), (F20N0) as a treatment.. Data were recorded on Potato leaf area, plant height, leaf length, leaf number, leaf diameter, stem diameter and stem number. The result revealed that the combination of various level of Farmyard manure and nitrogen statistically (p≤0.05) affected leaf area, plant height, leaf length, leaf number, leaf diameter, stem diameter and stem number. The maximum values for leaf area, plant height, leaf length, leaf number, leaf diameter, stem diameter and stem number were recorded from (F0N70, F20N70, F0N70, F20N35, F20N0, F20N70, F20N0) respectively .However The minimum values of all the parameters were recorded from the control treatment (F0 N0). From the study it could be concluded that Potato yield components were greatly affected by different rates of organic and inorganic fertilizers. The appropriate amount of different rates of fertilizers (farmyard manure and nitrogen) should be used to increase Potato growth and yield.

Grand Rapids no sistema hidropônico por capilaridade. Comparou-se capilares com 1 ou 2 cordões, de diferentes composições físico-químicas, no cultivo hidropônico de alface para um experimento conduzido em casa de vegetação. Os tratamentos consistiram na adoção de dois tipos de capilares, utilizando 1 ou 2 unidades por tratamento (sem aeração), contrastando com o cultivo convencional (sistema sem capilar e aerado artificialmente - testemunha). Foram avaliados os seguintes parâmetros: altura da parte aérea, comprimento da raiz, número de folhas, volume de raiz, teores de água nas folhas, relação parte aérea/raiz, acúmulo de nitrogênio na planta, Eh, pH, condutividade elétrica, N-NO3-, N-NH4+, P, K, S e B na folha. O cultivo hidropônico convencional não diferiu do cultivo hidropônico por capilaridade quanto ao número de folhas, volume de raiz, crescimento radicular, matéria seca da parte aérea, matéria seca da folha. Os cultivos hidropônicos capilar sem arejamento e, sem capilar e sem arejamento apresentam a mesma qualidade de produção quando comparado com o sistema convencional com arejamento através de compressor, sendo este último sistema muito mais oneroso, uma vez que requer gasto de energia elétrica para bombeamento de água. UNITERMOS: Lactuca sativa L,  nutrição mineral.  SILVA, J.

A.  GROWTH AND MINERAL COMPOSITION OF LETTUCE ON CAPILLARY HYDROPONIC SYSTEM  2 ABSTRACT This study evaluated the growth and mineral composition of lettuce cv Grand Rapids in a capillary hydroponic system. An experiment, carried out in greenhouse, compared different physical and chemical composition capillary with 1 or 2 strings in a hydroponic lettuce cultivation. Treatments consisted of 2 types of capillary, using 1 or 2 units per treatment (without aeration) compared to conventional cultivation (non-capillary system with artificial aeration – control system). The following parameters were evaluated: shoot height, root length, leaf number, root size, leaf water content, shoot/root relation, nitrogen accumulation in plant, Eh, pH, electric conductivity, N-NO3-, N-NH4+, P, K, S and B in the leaf. The conventional hydroponic cultivation did not differ from the capillary hydroponic system in relation to leaf number, root size, root growth, shoot dry matter and leaf dry matter. The hydroponic cultivation without aeration and the one without aeration and capillary presented the same production quality when compared to the conventional system with artificial aeration. Thus, the latter is a more expensive system once electricity is required to operate the water pumping system. KEYWORDS: Lactuca sativa L, mineral nutrition.
