Abstract

Water scarcity is the main factor causing crop production decrease and harvest failure in the upland areas. To improve water use efficiency by plants, Management Allowable Depletion (MAD) concept can be applied. MAD is the degree of soil dryness that still lead to optimum crop yied. This research was aimed to: 1) determine a correct MAD-level in order to achieve the optimum water use efficiency and 2) evaluate the effect of irrigation water sources on water use efficiency. The research was carried out on a Typic Kanhapludults at Tamanbogo Experimental station, East Lampung in dry season of 2005. Chili (Capsicum annum) was use as an indicator crop. The size of experimental plot was 5 x 10 m, that was arranged in split-plot design with 3 replications. The treatments were irrigation water sources designed as main plot which consisted of: A1 = ground water A2 = surface water, while MAD-level was designed as sub-plot, which consisted of : I1 = 20% of available water, I2 = 40% of available water, I3 = 60% of available water, I4 = 80% of available water, and I5 = 100% of available water. Irrigation was provided to reach 80, 60, 40, and 20% available water respectively. For the I5 treatment, irrigation was applied every day. The results showed that MAD-level of 60% of available water (I3) with the average of 9.6 mm of irrigation water, applied every three days, gave themost optimum crop yield and water use, thus achieving the highest water use efficiency. The surface irrigation water had a better quality than ground water,leading to a better plant growth, a higher crop yield and a higher water use efficiency than ground water

Abstract

Acid upland soil in Indonesia has a potential for agricultural development but it has constraints low of organic C and available P as well as the soil physical properties have been degraded. The use of manure and direct application phosphate rock (PR) was an alternative to improve land productivity and crop yields. The objective of the study was to examine the effects of manure and the sources of P on soil physical and chemical properties and yield of foods crop that was arranged on intensive cropping systems of upland rice + maize -/- cassava- mungbean. The experiment was carried out at Tamanbogo Station Farm, East Lampung since 2007 until 2009 using randomized completely block design with 3 replications. The treatments were (1) 10 Mg ha-1 manures + 1 Mg ha-1 of RP, (2) without manure + 1 Mg ha-1 of PR, (3) 10 Mg ha-1 manures + 100 kg ha-1 SP 36, and (4) without manure + 100 kg ha-1 SP 36. The results showed that the application of manure along with PR improved soil chemical and physical characteristics. Its improvement affected the yield of foods crops, hence the profit increased with B/C ratio between 2.88-3.60.

Abstract

The silt pit is a method of soil management that functions to accommodate and absorb surface runoff. The research aimed to determine the silt pit effectiveness for erosion reduction and nutrient loss. The research is located at 576 above sea level (asl) in Sukamantri village, Taman Sari district, Bogor Regency. The experiment used a randomized block design with three replications and a slope group. The treatments were R0 (without silt pit); R1 (silt pit); R2 (silt pit + mulch); R3 (silt pit + mulch + biopore tube), R4 (silt pit + mulch + biopore tube + vertical crop tube). The highest runoff-decreasing occurred on R4 treatment, which pressed down 29.38% runoff. The highest value of erosion-decreasing occurred on R2 as 68.74% and followed by effectiveness in reducing the loss of 71% Organic C, 76% available P, and 67% total N. The dry seeds peanut yield was around 0.54 - 0.86 Mg ha-1, dried pods was 0.96 - 1.33 Mg ha-1, and dried biomass was 5.16 - 6.23 Mg ha-1 and not significantly different between all treatments. This study recommends that farmers apply silt pit innovation technology with a combination of mulch, biopore, and mature green media because the incremental B/C ratio was 1.175. It is a good economic indicator for farmers.
