Pakistan is water stressed country in which agriculture is major consumer of fresh water supplies. The competition among agriculture, industry and domestic use leads us to acquire alternate source for crop production. However, the quality of alternate water source may result in deterioration of soil in general, particularly crops for human and animal consumption. The objective of present study was to evaluate the use of canal, domestic and municipal wastewater along with press mud application as alternate and improved farm management practices for sustainable food production. To explore the impact of wastewater and press mud on maize, one pot and two field experiments were conducted. The irrigation sources used in the study were municipal wastewater, domestic wastewater and canal water. While the nutrient sources were press mud and inorganic fertilizers. In the pot study different combinations of water qualities and nutrient sources were studied. The results showed that wastewater had adverse effects on the emergence parameters, whereas, press mud mitigated these effects. Seedling growth was good with more plant length and dry weight with municipal wastewater along with press mud followed by the domestic wastewater with press mud. Among the field experiments in first experiment, effect of press mud application under different irrigation waters (municipal wastewater, domestic wastewater and canal water) in comparison with inorganic fertilizers on yield and quality of hybrid maize was studied. In second field experiment, productivity of hybrid maize was tested under different irrigation treatments (T1=canal water, T2=domestic wastewater, T3=municipal wastewater, T4=alternate canal-domestic-canal, T5=alternate canal-municipal-canal, T6=mixed canal & domestic and T7=mixed canal & municipal). All the agronomic traits, plant height (cm), cob diameter, number of grain rows per cob, number of grains per cob, 1000-grain weight (g), biological yield (t ha-1) and grain yield (t ha-1) gave higher values with an increase of 22-27 % in grain yield under municipal wastewater irrigation with press mud in the first experiment over both the years. In second experiment municipal wastewater was best with statistically similar or followed by mixed canal & municipal and alternate canal-municipal-canal regarding the growth and yield components and the highest yield in both the years 2012 and 2013. Municipal wastewater irrigation along with press mud in first field experiment while, municipal wastewater as such or mixed with canal water significantly gave higher seed oil content (%), seed starch content (%) and seed protein content (%) in both the years of study. Seed heavy metal (Cd, Pb, Ni, Cu and Zn) contents were found to be within the limits proposed by international food quality standards in maize under all treatments.

58. Al-Mujadilah/The Pleading Woman

I/We begin by the Blessed Name of Allah

The Immensely Merciful to all, The Infinitely Compassionate to everyone.

58:01
a. Allah has heard the woman who was pleading with you, concerning the issue of her husband, and was complaining to Allah.
b. And Allah was hearing the conversation between you.
c. For Allah is All-Listening, All-Watching.

58:02
a. Those among you who estrange their women/wives by declaring them to be as their mothers;
b. should know that they can never be made as their mothers, for their mothers are only those who gave birth to them.
c. Indeed, they utter what is highly contemptuous, baseless and false.
d. Yet, assuredly, Allah will be Pardoning, Forgiving to the one who repudiates by zihaar through an atonement.

58:03
a. Those of the husbands who thus estrange their women/wives, then they wish to retract what they had uttered, let them free a captive before any skin-to-skin cohabitation between them.
b. Thus you are being warned so that you will never utter such contemptuous words again.
c. And Allah is Well-Aware of what you do.

58:04
a. And whoever cannot find any captive to set free or does not have the means of doing so, then let him keep Fast for two consecutive months, without any interruption, before any skin-to-skin cohabitation between them.
b. And whoever is unable for reasons of ill health or old age, then let him feed sixty poor people.
c. All this is decreed so that you may believe in Allah, HIS Injunctions and HIS Messenger.
d. And these are the limits set by Allah.
e. And the disbelievers/disobedient - those who will not comply...

Contestations and Transformations: the Shared Religious Space of Jhule Lal in Sindh, Pakistan

Syncretic and shared religious spaces have long been perceived as reflections of tolerance. This does not imply that tolerance is completely liberated from multiple clashing components and the coexistence of interfaith practices do not suggest that hostility is entirely missing. In recent times, a transformation is taking place at the shared space of the Jhule Lal by the dominant religious group. However, there remains an appearance of tolerance at the shared space of the Jhule Lal among believers of both Islam and Hinduism, which blinds the observer of the deep internal contestation and process of transformation between both Sindhi Hindus and Sindhi Muslims who revere the same saint of the Jhule Lal. A syncretic space does not simply absorb different religious groups, and by studying the practices, rituals and interactions of the custodians, visitors and devotees at the shrine, this paper aims to unearth the processes through which shrine is contested in multiple identities, discourse (written, textual, verbal) authority, and belief systems.

Varieal Evaluation and Quality Enhancement of Cut Tulips by Exogenous Application of Growth Promoting Substances

Tulips are one of the most popular springs of all the time and possess eminent status among various cut flowers cultivated world-wide next to rose and chrysanthemum in the global floriculture trade. However, they are not as productive in subtropical areas as they are in temperate zones. This is attributed by short span of winter season and other abiotic stress factors that are aggravated by climate change. All these factors impede tulip production in subtropical regions. Therefore, a study, comprised of four experiments was conducted to investigate the varietal response of different cultivars of cut tulips under Faisalabad conditions and role of various bioregulators on morpho-physiological, biochemical, enzymatic and ionic attributes that can be used for characterization of inducing tolerance and adaptability in tulip cultivars. Bulbs were planted in open field having sandy loam soil provided with supplemental doze of macronutrients. In first experiment, screening of 10 different tulip cultivars for their growth response and adaptability was carried out on the basis of their sprouting, morphological, floral and bulb attributes. Cultivars were categorized into best performing and least performing on the basis of their performance in 1st experiment. Five better adapted cultivars namely Apeldorn, Barcelona, Ile de France, Leen Vander Mark and Parade were selected for further study. In 2nd and 3rd experiment exogenous application of chitosan and glycine betaine, respectively were carried out to assess the performance of various attributes for quality enhancement. Moreover, in 3rd experiment, response of different polyamines (putrescine, spermine and spermidine) was studied in two cultivars Apeldorn and Clear water by their exogenous application at different concentrations. Results of 1st experiment depicted highly significant difference among all the tested cultivars that all varieties behaved differently and some of them showed better adaptability that have potential for production on commercial basis in the country. Furthermore, optimized levels of chitosan and glycine betaine were also identified that enhanced the growth response of different tulip cultivars. Inferences were developed on the basis of standards needed for any cut flower crop like increased quality parameters flower size, stem length, freshness and postharvest attributes. Results depicted exogenous application of chitosan and glycine betaine improved plant fresh mass, height, leaf area, chlorophyll contents, photosynthetic rate (A), transpiration rate (E), water use efficiency (WUE), stomatal conductance (gs), sub-stomatal CO2 (Ci), antioxidant enzymes and all other attributes associated to flower morphology. Furthermore, these compounds also improved the postharvest longevity by causing significant decrease in MDA contents. Though the chemicals used did not improve the mass, diameter and number of perrenating organs, thus they imparted negative effects on bulb attributes necessary for the growers to use them in the preceding year. In 4th experiment, 0.03 mM spermine (Spm) concentration proved to be the best for enhancing flower quality attributes in Apeldorn cultivar while low level of spermine (Spm) 0.01 mM proved to be best amongst all other tested dozes of polyamines in Clear water cultivar. Overall best performing traits were found in the plants that were exogenously applied by spermine followed by spermidine while putrescine improve petal lengths and width while other attributes remained less affected. Furthermore, findings of 4th experiment clearly indicated that spermine significantly enhanced postharvest potential of both the tulip cultivars by sustaining vase life and improving physiological, biochemical and enzymatic attributes. Overall, it can be extracted that suboptimal environmental conditions were found to be injurious for tulip growth and productivity and exogenous application of chitosan and glycine betaine specific concentration for particular cultivars were found effective tool for enhancing growth potential. However, effect of polyamines was more pronounced in both the cultivars reflecting that it may induce similar effects on other tulip cultivars as in majority of the parameters varietal effect was found to be non-significant. Besides, one can establish that A, E, WUE, gs, gm and protein might directly be linked with growth and flower quality attributes as they are severely affected by malicious environmental conditions. Thus it can be concluded from the current findings that by planting better performing cultivars, identified in the research, the growth potential of tulip can be expanded. The application of optimized levels of chitosan and glycine betaine particularly at lower levels proved effective in extending display life of tulips. Both these strategies when applied together could lead to a breakthrough in tulip cut flower production by improving the flower quality achieved through minimizing the life cycle in short duration of winters in sub-tropical terrains.
