Plant Water Balance

Ketersediaan air tanah yang sebagian besar berasal dari curah hujan merupakan faktor pembatas yang penting bagi peningkatan produksi suatu tanaman. Neraca air merupakan suatu metode yang dapat digunakan untuk melihat ketersediaan air tanah bagi tanaman pada waktu tertentu. Prosedur perhitungan neraca air dibuat berdasarkan sistem tata buku Thorntwaite dan Mather (1957) dengan satuan tinggi air (mm). Analisis ketersediaan air tanah secara grafik disajikan dalam periode bulanan, mulai Januari hingga Desember secara klimatologis. Data yang digunakan dalam analisis ini adalah data rata-rata jumlah curah hujan bulanan dan suhu rata-rata bulanan tahun 1985-2011 dari Stasiun Klimatologi Pulau Baai Bengkulu yang mewakili daerah penelitian yaitu wilayah Kota Bengkulu dan data tanah Kota Bengkulu. Wilayah Kota Bengkulu memiliki ketersediaan air yang sangat cukup dengan persentase air tersedia setiap bulannya 100%, yang dibuktikan dari hasil perhitungan, oleh karena itu Kota Bengkulu memiliki nilai surplus sepanjang tahun. Pada kondisi jumlah curah hujan bulanan yang cukup tinggi berkisar 179 - 458 mm, suhu yang relatif rendah berkisar 25,9 - 26,9 ˚C, dan lahan dengan nilai surplus yang tinggi seperti ini, di wilayah Kota Bengkulu baik untuk ditanami padi, sedangkan untuk penanaman jagung kurang baik.Kata kunci: neraca air, curah hujan, kesesuaian lahan, suhu udara, klasifikasi oldemanABSTRACTThe availability of groundwater most of which comes from rainfall is an important limiting factor for increasing the production of a plant. Water balance is a method that can be used to see the availability of ground water for plants at a certain time. The water balance calculation procedure is based on the Thorntwaite and Mather book keeping system (1957) with water unit (mm). Analysis of groundwater availability graphically is presented in monthly periods, from January to December climatologically. The data used in this analysis is the average data of the amount of monthly rainfall and the average monthly temperature of 1985-2011 from Bengkulu Island Climatology Station representing the research area of Bengkulu City and Bengkulu City land data. Bengkulu City has a very good water supply with percentage of water available every month 100%, as evidenced from the calculation, therefore Bengkulu City has surplus value throughout years. While conditions of high monthly rainfall is quite high ranging from 179 - 458 mm , Relatively low temperatures ranging from 25.9 - 26.9 ˚C, and land with a high surplus value like this, in the area of Bengkulu City is suitable for planting rice, whereas for the planting of maize is less suitable.Keywords: water balance, rainfall, land suitability, air temperature, oldeman classificationCitation: Paski, J.A.I., Faski, G.I.S.L., Handoyo, M.F. dan Pertiwi, D.A.S.

Plant Water Balance

The water balance of soybean (Glycine max), cowpea (Vigna unguiculata), black gram (Vigna mungo), and pigeonpea (Cajanus cajan) grown in pots was studied during a soil drying cycle. The response of the plants was analysed for three distinct stages of dehydration. In stage I, the rate of transpiration remained constant and equal to that of well watered plants even though soil water status fell by more than 50%. Stage II began when the rate of soil water supply to the plant was less than potential transpiration and stomates closed resultingjn the maintenance of plant water balance. When soil water content was expressed as a fraction of transpirable soil water, all species showed a transition from stage I to stage II at a fraction of transpirable soil water of about 0.3 to 0.2. As the soil water declined further, all species had a similar decrease in relative transpiration rate. Consequently, the responses of the four species in stages I and II were essentially identical, except that pigeonpea extracted a slightly greater amount of soil water. Stage III occurred once stomates had reached minimum conductance and water loss was then a function of the epidermal conductance and the environment around the leaf. Substantial differences were found among the four grain legumes in epidermal conductance. Soybean had the highest conductance, followed by black gram, cowpea and pigeonpea. Substantial variation in dehydration tolerance among the four grain legumes was also found: the ranking of dehydration tolerance based on the relative water content was pigeonpea > cowpea > mungbean > soybean. Differences among the four grain legume species in the duration of stage III which finished when plants died, were consistent with differences in epidermal conductance and in dehydration tolerance of leaves.
