RESPON PERTUMBUHAN DAN PRODUKSI DUA VARIETAS TANAMAN KEDELAI (Glycine Max. (L) MerrilI) TERHADAP PENIPISAN AIR TANAH TERSEDIA
ABSTRACT: All this time,
efforts to improve soybean productivity is still based on the expansion of
planting area (Badan Pusat Statistik, 2013), but production
is still declining. It is also
influenced by the lack of
understanding about the cultivation
of soybeans and the price is less promising causing farmers are reluctant to
plant soybeans. This research aims to
investigate the response of the growth and production of two varieties of
soybean (Glycine max. (L) Merrill) to some degree of available soil water
depletion. This research was conducted
at the Laboratory of Integrated Courses Faculty of Agriculture, University of
Lampung, in May up to August 2014, using factorial design in a completely
randomized design with the first factor is depletion of groundwater available
(P) which is composed of four levels of available soil water depletion
treatment (ATT) is the treatment P1 (0-20%), P2 (0-40%), P3 (0-60%), and P4
(0-80%) and the second factor, namely soybean varieties (V), which consists of
varieties V1 (Wilis) and V2 (Kaba), with three repetitions. Results were
analyzed by F test at LSD further by 5% and 1% by using Statistix8
Program. The results showed that the
effect of the level of available soil water depletion during the vegetative stage and
generative phase did
not significantly affect plant
growth and crop yield. The
highest production yield and Wilis varieties Kaba obtained at a rate of
0-40% thinning. Based on these values
concluded that to produce optimal production in both varieties can still be
maintained until the level of depletion of available soil water content to 40%.
