Perilaku Petani dalam Menghadapi Fluktuasi Harga Sawit Menurut Perspektif Ekonomi Syariah

The frequently fluctuating price of palm oil causes palm oil farmers in Tanjung Kudu, Kualu Village, to take action to overcome their family's economic problems as a result of prices fluctuating drastically. The aim of this research is to determine the behavior of oil palm farmers in facing price fluctuations and to determine the Islamic economics review of the behavior of oil palm farmers in facing price fluctuations in Tanjung Kudu, Kualu Village. This research is field research located in Tanjung Kudu, Kualu Village. The informants in this research were 10 oil palm farmers with the criteria being farmers who had a plantation area of more than 2 hectares and had worked for a minimum of 5 years. Data collection techniques through observation, interviews and documentation. Data analysis is descriptive qualitative. It was found that oil palm farmers carry out various kinds of behavior to increase family income, such as working side jobs, becoming farm laborers, construction workers, traders, and others. Some of the oil palm farmers' wives also help in increasing the family's income by opening small businesses such as opening a breakfast business, a daily shop business, and a laundry business. The behavior of oil palm farmers in facing price fluctuations applies the principle of honesty, always trying to earn a living, not being discouraged, never giving up, being responsible for family needs, and not being lazy in working.  

Phosphorus Dynamics and its Uptake by Wheat in Salt-Affected Soils

In some serious environmental constraints, soil salinity is a worldwide major issue for crop production and soil declination. Salinity in Pakistan has covered 6.68 million hectares area of cultivated land and further out of 6.68 million hectares 56% area is covered by saline sodic. The soil salinity causes hindrance in the availability of very essential macronutrients like phosphorus. The relation between phosphorus uptake and soil salinity is a complex phenomenon. With the aim to calculate phosphorus (P) fractions and to maximize P bioavailability in wheat crop, a series of pot and field experiments were conducted in normal and salt affected soils. In 1st incubation study rate of P was selected on the basis of plant available P at different time intervals from three different rates (200, 400 and 600 mg kg-1 of soil) of P fertilizer. Results revealed that among different fractions of P (bound and bioavailable), maximum Olsen-P was found 12.18 mg kg-1 in PROKA soil (saline sodic), 9.225 mg kg-1 in PARS soil (saline) and 9.125 mg kg-1 in UAF soil (normal), when P was applied at 400 mg kg-1 of soil. Selected rate of P fertilizer (400 mg kg-1) was used in 2nd incubation study with different organic amendments [farmyard manure (FYM), poultry manure (PM), crop residue (CR)] and sewage sludge (SS) for the determination of P fractions at different time intervals. Plant available Olsen-P fraction significantly increased after 90 days of incubation in all soils (normal, saline sodic, saline) with amendments FYM and PM but not as much with amendments CR and SS at P application level 400 mg kg-1 of soil. Overall, Olsen-P was increased maximum with PM (23.2, 21.7 and 19.4 mg kg-1) and FYM (20.6, 17.6 and 20.6 mg kg-1) as compare with SS (14.3, 15.5 and 15.7 mg kg-1) and CR (12.9, 14.4 and 14.0 mg kg-1) in normal, saline sodic and saline soils, respectively. To evaluate the effect of P rate (400 mg kg-1) selected from 1st study and organic amendments (FYM and PM) selected from 2nd study, A subsequent pot experiment was conducted in normal (UAF) and salt-affected (PROKA and PARS) soils. Results showed a significant effect on wheat growth, yield, physiological, chemical and biochemical parameters by combined application of P + PM in all soils. On the basis of these parameters, P + PM remained as best in normal and salt-affected soils with order of normal>saline>saline sodic. In pot experiment, maximum level of grain yield (24%), photosynthesis (37%), protein (20%), fat (40%), starch (41%) and maximum reduction in polyphenol (47%) were observed by combined application of P + PM, over control. Highest level of P in root xviii (53%), shoot (57%) and grain (121%) was found in wheat plant grown in normal soil while maximum level of Olsen-P (99%) was observed in saline sodic soil by P+PM treatment, over control. In field experiment, results showed that growth parameters such as plant height, root dry weight and 1000 grain weight were increased maximum with PM + P treatment in all soils. Photosynthetic parameters also affected significantly in all three types of soils by combined application of PM + P. Significant effect of combined application of P fertilizer and PM was recorded in case of P concentration in wheat root, shoot and grain in all soils. Biochemical parameters such as protein, fat, fiber, ash, starch and polyphenols were also affected significantly with treatment PM + P. Overall these experimental results showed that P fertilizer applied with PM, not only improved wheat growth, yield and physiology but also improved grain nutritional value and P uptake in both type of soils (normal and salt-affected). Reduction in adverse effect of soil salinity was also observed by integration of chemical fertilizers and organic amendments.
