Resumo: A pimenta é uma olerícola importante na agricultura brasileira, tendo em vista o seu vasto uso culinário. Para que a cultura estudada se desenvolva satisfatoriamente é necessário o manejo adequado da irrigação. Com base na importância dessa cultura, objetivou-se com este trabalho avaliar o efeito de lâminas de irrigação nos componentes de produção de duas espécies de pimenta do gênero Capsicum. O experimento foi desenvolvido em condições de campo, na fazenda do CEUNES/UFES, em São Mateus, no Espírito Santo, Brasil. Empregou-se o delineamento experimental em blocos inteiramente casualizados, em parcela subdividida, com quatro repetições. As parcelas consistiram de cinco lâminas de irrigação, correspondendo a 40%, 70%, 100%, 130%, 160% da evapotranspiração de referência (ETo) de Penman Monteith (FAO 56). Nas subparcelas foram avaliadas duas espécies de pimenta, sendo: Capsicum baccatum, da variedade Dedo-de-Moça, e a Capsicum chinense, da variedade De Cheiro. Avaliou-se a produtividade, a massa média, o diâmetro médio, bem como o comprimento dos frutos. As lâminas de irrigação apresentaram efeitos apenas para a produtividade e para a massa média dos frutos de pimenteira. Os componentes de produção da pimenta de 'De Cheiro' foram superiores aos do 'Dedo-de-Moça', para as condições edafoclimáticas de São Mateus-ES.Palavras-chave: Capsicum baccatum. Capsicum chinense.

For satisfactory crop development, suitable irrigation management is necessary. Based on the importance of this crop, the aim of this work was to evaluate the effect of irrigation depths on the production components of two species of pepper of the genus Capsicum. The experiment was carried out under field conditions on a farm of CEUNES/ UFES in São Mateus, in the State of Espirito Santo, Brazil (ES). The experimental design was completely randomised into blocks of split lots, having five lots, two sub-lots and four replications. The lots comprised the irrigation depths of 40%, 70%, 100%, 130% and 160% of the Penman Monteith reference evapotranspiration (ETo) (FAO 56). In the sub-lots, two species of pepper were evaluated (the Lady's Finger variety of Capsicum baccatum, and the Yellow Lantern variety of Capsicum chinense) employing drip irrigation. Under evaluation were productivity, average weight, average diameter and fruit length. Irrigation depth affected productivity and average fruit weight only. For the soil and climate conditions of São Mateus, ES, the production components of the Yellow Lantern pepper were higher than those of the Lady's Finger.

“…The highest tested salinity (T 3 ) reduced plant height (7.71%) compared to T 1 (fresh water) after 120 days after transplanting (DAT). Cetin and Demet (2008) reported that canopy cover of tomato crop increased and reached maximum (70-100%) value at the middle of crop growth period and afterwards it remain constant until end of growing season. On the other hand the obtained results showed that the different discharge rates significantly affected the plant height.…”

The use of alkali ground water constitutes a major threat to irrigated agriculture in semiarid parts of India. The entire arid and semiarid region in India is characterized by low rainfall and has the problems either of water scarcity or poor quality ground water and it can be better utilized for irrigation through drip irrigation system. An experiment was conducted on tomato crop at Central Institute of Post Harvest Engineering and Technology (CIPHET) Abohar, Punjab to study the effect of blending fresh and saline irrigation water on yield and quality. The good quality canal water (EC of 0.38 dS/m) and ground water (EC 19.5 dS/m) were mixed in ratio of 100% Fresh (F), 75:25 (Fresh: saline; F:S) and 50:50 (F:S). The irrigation was done through drip system with three discharge rates (1.2, 2.4 and 4.2 lph) at three irrigation levels of 0.6, 0.8 and 1.0. The plant yield decreased significantly with increase in salinity levels of irrigation water (that is, increase in proportion of saline water). The maximum plant yield (3.55 kg/plant) was recorded with fresh water irrigation while 50% saline water blending in irrigation produced the lowest yield (2.64 kg/plant). The average yield decreased significantly when the discharge rate of emitters increased from 1.2 to 2.4 lph. The quality of tomato is observed inferior in saline water treatment compared to fresh water treatment. The TSS and acidity of tomato fruits increased with increase in the saline water ratios of irrigation water. As compared to 100% fresh water treatment, the mixing of 75% fresh and 25% saline water reduced tomato yield by 11% and gave a better quality tomato fruits at the discharge rate 2.4 lph and irrigation level 0.8. Hence, saline water can be utilized through drip system for sustainable yield and quality tomato production in water scarce area having poor quality ground water.
