13. Ar-Ra’d/The Thunder

13. Ar-Ra’d/The Thunder

I/We begin by the Blessed Name of Allah

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

13:01
Alif. Lam. Mim. Ra’.
These are the Messages of the Divine Book – The Qur’an.
What is revealed on to you – O The Prophet - from your Rabb - The Lord is the truth.
Yet most people do not believe it to be so.

13:02
It is Allah WHO raised up the celestial realm without any visible support as you can see.
Then, HE established HIMSELF upon the Throne of Almightiness.
And made the sun and the moon subservient to HIS laws, each running its predetermined course until the Last Hour.
Thus, HE directs all matters, distinctly explaining every sign of HIS Almightiness so that you may be convinced of the meeting with your Rabb - The Lord.

13:03
And it is HE WHO spread out the earth, and placed firm mountains upon it, and running
rivers,
and made two of a pair of every fruit/plant-vegetation,
and HE covers up the daytime with the nighttime.
Indeed, these are the wonders of HIS Unique Creative Power for a people who reflect.

13:04
And on the earth, there are tracts of land adjoining one another, and yet different from one another, and
vineyards, and
sown fields, and
date-palms,
growing in clusters from a shared root or not of a shared root,
yet they are all irrigated by the same one water stream.
And yet WE favor some of its fruit in flavor and taste over others.
Surely in that are wonders of HIS Unique Creative Power for a people of understanding.

The Impact of SMEs on the Economic Development of Pakistan

Pakistan is a country where the expansion of the industrial sector is necessary, and in this process, the relative significance of the Small and Medium Enterprises (SMEs) sector cannot be overstated. SMEs comprise approximately 90% of total businesses in Pakistan; nearly 80% of the workforce other than the agriculture sector is employed by the SMEs; and approximately 40% of GDP is contributed by the SMEs.1 Though, the growth of SMEs is constrained by financial and other resources that is not faced by Large Scale Manufacturing (LSM) sector. From the facts and figures presented in this paper, it can be concluded that SMEs perform a dynamic role in the growth of all the related sectors of the economy. This study empirically analyzes the effect of innovation and activities of SMEs on economic growth of Pakistan over the span of 19732017. The study concludes that the activities of SMEs do influence the economic development of Pakistan.

Sustainable Management of Aphids on Canola in Organic and Inorganic Farming Systems in Punjab, Pakistan.

Canola (Brassica napus L.) is the second most important source of vegetable oil after soybean. Its oil is widely used in cooking and for making salads and margarines, while the meal is commonly used in animal feeds all around the world. Pakistan, being an agricultural country, is still essentially deficient in edible oil production. It is estimated that more than three fourths of the country’s vegeTable oil requirements are met through imports. Canola is one potential crop which can fulfill the country’s requirement for edible oil. Insect pests are a major yield limiting factor of this crop. Among the insect pests, aphids are considered the major pest. Three aphid species are known to infest the canola crop, the cabbage aphid, Brevicoryne brassicae (L.), the turnip aphid, Lipaphis erysimi Kalt, and the green peach aphid, Myzus persicae (Sulzer) (all are Hemiptera: Aphididae). Heavy aphids attack on canola seedlings can cause wilting of the cotyledons and yellowing of the leaves. Heavy infestations of aphids on pods and flowers lead to yield reductions. Normally aphids cause about 30-35% yield losses on brassica plants but under uncontrolled situations the yield losses may exceed 70%. Control of the pest relies exclusively on pesticides. The indiscriminate use of pesticides has resulted in the development of resistance and resurgence by pests together with associated environmental and health hazards. This situation urgently demands alternate bio-intensive control measures as the main components of an IPM program. The present study was conducted on sustainable management of aphids on canola grown under organic and conventional farming systems in Punjab, Pakistan. The main objective of this study was to develop the most economical and effective management models by determining population distribution of aphids and their natural enemies, screening relatively tolerant crop genotypes, to identify sources of resistance, studying the biology of aphids and determining the efficacy of mechanical, biological and chemical practices for pest suppression. The results of these findings revealed that the cabbage aphids and mustard aphid were found in all four locations studied (Faisalabad, Bahawalpur, Khanpur and D.G. Khan) while the green peach aphid was recorded at two locations (Faisalabad and Khanpur).The genotypes ‘Cyclone’ , ‘Shiralee’ and Oscar were found to be susceptible with maximum population of aphids. The genotypes ‘Hyola-401’ and ‘Rainbow’ were observed to be relatively resistant with lower populations of aphids. The results regarding the biochemical basis of resistance revealed that the availability of nitrogen increases susceptibility, and crop genotypes and farming systems with more nitrogen inputs suffered higher aphid populations. The different evaluated farming systems significantly affected the total life span of aphids, and maximum numbers of nymphs were produced on canola grown under fertilizer applications. All tested insecticides (Carbosulfan, Acetamaprid, Imidacloprid, Nitenpyram and Profenofos) were found to be effective against aphids and reduced population densities. Results revealed that treatments consisting of chrysoperla + coccinellid + blank water spray were highly effective against aphids on canola under both systems of farming. Predators performed well one week after release and their efficacy increased over time. A higher and noticeable yield was obtained under inorganic farming system where Chrysoperla carnea, coccinellids and blank water spray were integrated or blank water spray was applied. However, a higher CBR (10.36:1) was attained under organic (farm yard manure application) where blank water spray was applied on the canola crop. Integration of C. carnea, coccinellids and blank water spray under organic farming system also produced a rationally higher CBR (4.02:1). In conclusion, organic farming system (FYM application) with blank water spray or integration of C. carnea, coccinellids and blank water spray is better option and recommendation for aphid management in canola.
