Kashmir: Occupation and Resistance

Kashmir became a part of the Muslim World in the 14th century C E. Under the local Sultans (1325-1585) , the Mughals (1586-1752) and the Pathans (1752-1819) , it developed into a state and society with its own peculiar Islamic culture. Kashmir was colonised by the Sikhs (1819-46) from the Punjab and the Hindu Dogra Maharajas (1846-1947) . The Muslim Kashmir stood for Islam through the freedom movement during this period. When the movement under the banner of Islam was at its apex and it seemed that the mahkutn (colonised / enslaved) Kashmir was about to achieve the goal, India ( Bharat) , a newly born nation (Aug 15, 1947) , invaded it on Oct. 27, almost 3 months after her own birth. Since then this newly emerging occupying -power through its policies of political deceit, cultural aggression, economic onslaught and delslamizing educational schemes has given rise to the problem of the IOK (Indian Occupied Kashmir) . The paper narrates the story of the past up to 1988-uprising & throws light on the oppression, persecution and discrimination that the Muslim Kashmir has been witnessing. The form offreedom-movement that followed from 1947 to 1989 is also outlined. In 1989 Jihad Kashmir, a new phase of the movement that invited the attention of the world begins. The paper helps to understand the background ofthe genesis ofthis new phase

Prediction of Cotton Leaf Curl Virus Disease and its Vector Based on Epidemiological Factors and its Management

Cotton is an important commercial crop of global importance. Cotton is known as the backbone of Pakistan’s economy. Cotton leaf curl virus disease (CLCuVD) is a serious threat to the successful cotton production and is transmitted by whitefly Bemisia tabaci Gennadius under field conditions. A disease and vector predictive model based on 5 years epidemiological factors was developed and validated based on 2 years epidemiological factors for the prediction of CLCuVD and its vector. Y= 145+ 4.47x 1 -0.151x 2 -0.490x 3 -1.83x 4 +1.58x 5 -4.84x 6 R 2 = 0.79 (Five years data) Y= 145+ 2.78x 1 - 0.998 x 2 -0.400 x 3 -1.02 x 4 +3.85 x 5 -2.25 x 6 R 2 = 0.75 (Two years data) Where y = CLCuVD, x 1 = Minimum temperature, x 2 = Rainfall, x 3 = Relative humidity, x 4 = Wind velocity, x 5 = Whitefly, x 6 = Maximum temperature. Y= 57.0 - 0.370x 1 - 0.0853x 2 -0.297x 3 +0.813x 4 -0.565x 5 R 2 = 0.64 (Five years data) Y= 27.5-0.726x 1 -0.511x 2 -0.122x 3 -0.177x 4 +0.639 x 5 R 2 = 0.58 (Two years data) Where y = Whitefly, x 1 = Maximum temperature, x 2 = Minimum temperature, x 3 = Relative humidity, x 4 = Rainfall, x 5 = Wind velocity. A significant (P<0.05) but negative correlation was observed between maximum temperature and CLCuVD. The value of the coefficient of correlation was observed in the following order: 2006 (r=0.80*) < 2004 (r=0.79*) < 2005 (r=0.76*) <2002 (r=0.61*) and < 2003 (r=0.60*). Except 2006, the relationship of CLCuVD with rainfall was found non- significant during the subsequent years (r < 0.47). Wind velocity was found non- significant but negatively correlated with CLCuVD. Whitefly had significant and positive correlation with CLCuVD during all the five years. The relative humidity contributed significantly in the build up of whitefly population during 2005 only (r=0.60). During rest of the years relative humidity did play a prominent role in the spread of this vector as was evident from the value of correlation coefficient 0.34 ≤ r ≤ 0.47. The wind velocity did not contributed as effectively as compared to other variables. None of the screened varieties/advanced lines was found to be immune against cotton leaf curl virus disease and varied greatly in response to disease incidence during both the years (2007-08). Only three varieties/advanced lines (NIBGE-2, PB-899, NIAB- 884) were found to be highly resistant against CLCuVD. Eight cultivars (BH-162, NIAB- 824, CIM-496, MJ-7, CIM- 446, CIM-473, VH-148, Alseemi hybrid) were found to be resistant. Six varieties/advanced lines (NIAB-111, PB- 897, FH-2925, CIM-438, CIM-497, FH-115) were found moderately resistant. Five cultivars (FH-900, CIM-707, CIM-506, FH-901, CIM-498,) were observed to be moderately susceptible and five varieties/advanced lines (PB-843, FH-1000, BH-163, CIM-482, CIM-443) exhibited susceptible response. Five varieties/advanced lines (CIM-534, FH-2000, FH-2006, MNH-732, S-12) were found to be highly susceptible against cotton leaf curl disease, respectively. All the treatments reduced whitefly population and CLCuVD incidence significantly compared to untreated control. Azadirachta indica (Neem) extract was the most active to manage the B. tabaci population. Salicylic acid was at number second and Eucalyptus globules (Sufaida) was at number third whereas Allium sativum (Garlic) and Calotropics procera (Ak, Akund) were at number four and fifth respectively in managing the B. tabaci and CLCuVD. Aloe babadensis (Aloe) and Datura stramonium (Datura) were found less effective compared to other treatments.
