Abstract

Udipsamment  is  characterized  by  sand  fraction  > 95%,  loose,  and  very  high  leaching. This  study  aimed  to determine  the  effect  of  mineral  soil  ameliorants  and  adhesive  polymers  on  the character  of  nutrient leaching  in  Udipsamment.  The  leaching   study  in  lysimeters  used  a completely  randomized  design  with three  replications.  The  treatments  consist  of  bagasse  (B),  mineral  soil included  Inceptisol  (I)  and Vertisol  (V),  and adhesive  polymers included tapioca  1% and 2% (T1  and  T2),  tapioca  dregs  1%  and  2  %  (A1 and  A2),  Polyvinylalcohol  0.1%  and  0.2%  (P1  and  P2).  Combination  of  treatments  are  IB,  VB,  IBT1, IBT2,  VBT1,  VBT2,  IBA1,  IBA2, VBA1 ,  VBA2 , IBP1,  I BP2, VBP1,  and  VBP2.  Observations  were made  before  and  after  leaching.  The  research  showed  that  VBT2  increases moisture-holding  capacity. Amelioration improved the ability of  Udipsamment  to  hold  nutrients,  after leaching  for  six  months,  there was  a  decrease  in  organic  C,  total  N,  and  available  P  compared to before  leaching.  Amelioration increased the  soil  CEC,  even up  to  the  sixth  month  leaching,  the soil  CEC  showed  a  higher value  than  before  leaching.  The  amount  of  clay  fraction  was  relatively  uniform  between  the  surface  and  the  bottom of  the lysimeter,  indicating that   the adhesive   polymer  successfully  bonding  the  clay-sand  particles  and prevented clay leaching.

Abstract

Dryland has the potential to increase agricultural production, by increasing the cropping index. The main problem of dryland is the availability of water which depends on rainfall. Groundwater can be an alternative option to meet the availability of water in the dryland. This study aimed to determine the cropping pattern and increase of cropping index supported by groundwater irrigation in the dryland. The research was conducted in the dryland of Playen, Gunungkidul, Special Region of Yogyakarta, supported by groundwater irrigation. This research used a combination of survey, interview and plot demonstration methods. Surveys and interviews were conducted to determine the condition of cultivation and profit in the first and third growing seasons. The plot demonstration, to increase the rice cropping index from 1 to 2, was applied in the second growing season. The results showed that rice productivity in the first growing season was 5.215 ton ha-1, with a profit of 12,288,000 IDR ha-1 and B/C of 1.28. In the second growing season, Sidenuk productivity was 8.025 ton ha-1, with the dry straw of 8.049 ton ha-1, grain carbon of 3.471 ton ha-1 and straw carbon of 3.723 ton ha-1, higher than those of Situbagendit, but comparable those of Inpari-42, with a profit of 20,700,000 IDR ha-1 and B/C of 1.54. Rice contributed to higher biomass, carbon and profit than groundnut. In the third growing season, groundnut productivity was 2.026 ton ha-1, with a profit of 15,572,000 IDR ha-1 and B/C of 1.78. Groundwater irrigation can support the increase in the cropping index on dryland and intensify agricultural production as well.
