Cultivars, Leccino had the highest number of fruits (7995 per tree), fruit yield (12.57 kg per tree) and oil content (7.04%), while cultivar Pendallino had the highest fruit set (12.67%) and cultivar Coratina had the highest fruit size (2.02 cm) at both locations. Pendallino ranked second to Leccino in number of fruits (5376per tree),fruit size (1.99 cm), and fruit yield (11.34 kg/tree) and oil content (6.53%). The number of fruits per tree, fruit set and oil content was higher at Chakwal location as compared to Sangbhatti. By contrast, the fruit size and fruit yield were higher at Sangbhatti location. Cultivar Coratina had the maximum fruit size but least oil content among the three cultivars studied. The interaction between C×L and C×L×Y significantly affected the fruit set, number of fruit, fruit size, fruit yield and oil content, while C×Y had significant affect on fruit set, number of fruit, fruit size and oil content. The interaction between L×Y also significant affected the fruit set and oil content. Cultivar Leccino is recommended for higher production of fruits and oil content at both the locations.

Olive fruits were gathered from a couple of varieties of olive plants i.e., Arbequina and Coratina in fully young phase from the orchards of different locations of Pakistan namely, Chakwal, Nowhera, and Quetta where the climate patterns are entirely different in regard to weather, rainfall, and altitude. The extracted oil which was taken after the mechanical pressure was analyzed in various quality parameters i.e., Peroxide value, Chlorophyll content, Vitamin E, etc. The average value which was observed was not affected (P≥0.05), but every figure was lying in the given accepted scale of the International Olive Council. Major change (P≤0.05) was observed in oil content for K232, K270, Chlorophyll contents, oleic acid, linoleic acid, palmitic acid, palmitoleic acid, total antioxidant potential and total polyphenols in both the cultivars and the different regions which are mentioned above. It was observed that the olive of the Nowshera location acquires maximum average value of linoleic acid (10.99%), Linolenic acid (1.01%) and palmitoleic acid (2.74%). The second highest average value of olive oil was found was that of Chakwal, whereas Quetta has lowest average value of olive oil. The maximum average content of K232 (3.13), K270 (0.48) and total antioxidant (48.48%) were recorded in district Chakwal. The second maximum mean values were found at Nowshera whereas, the lowest mean values of K232 (3.13), K270 (0.48) and total antioxidant (48.48%) were found at Quetta. The maximum content of oleic acid (72.59%), palmitic acid (19.00%) and total polyphenols (28.97) were found in the olive oil of Quetta succeeded by Chakwal whereas, the content of oleic acid (72.59%), palmitic acid (19.00%) and total polyphenols (28.97) were found lowest in the oil of Nowshera. In a nutshell, it is clear from the above-mentioned experiment which was performed at different locations; that changing climatic patterns has a significant effect on the quantity of the oil. It has also a significant impact quantitative production of olive oil.

Results revealed that different sowing dates, Ca, B treatments and their interaction significantly affected yield and quality parameters of potato crop. The application of Ca alone @ 0.06% significantly increased the large tubers plant−1 (2.0), total yield (18.6 t ha−1), survival (78%), dry matter content (18.3%) and starch content (14.6%) as compared to control treatment. Boron @ 0.04% also significantly enhanced large tubers plant−1 (2.1), total yield (18.7 t ha−1), survival (75%), dry matter content (18.2%) and starch content (14.9%) than control treatment. Foliar application of (0.06% Ca) + (0.02% B) resulted in the maximum number of large tubers plant−1 (2.5), total yield (20.5 t ha−1), dry matter content (19.5%) and starch content (16.2%) as compared to other treatment combination. Plant survival was maximum at (0.06% Ca) + (0.04% B). Increasing Ca, B concentration decreased in number of small size tubers plant−1. Early sown potato plants with the combined application of 0.06% Ca + 0.02% B resulted in maximum yield and quality characteristics as compared to the rest. So it is concluded that early planting in the first week of October with the combined application of 0.06% Ca + 0.02% B resulted in maximum yield and quality of potato.

In such regard, present study entitle as "Physical and chemical attributes of various cultivars of plum fruit" was elaborated at Agriculture Research Institute, North Mingora Swat during the year 2013, according to Completely Randomized Design (CRD). Significant differences were observed among all the attributes studied. The results revealed that the highest fruit weight (62.55 g), fruit volume (62.44 ml), fruit length (50.39 mm), stone weight (2.48 g), stone thickness (11.99 mm) were recorded in plum cultivar President, whereas the lowest fruit weight (27.44 g), fruit volume (31.22 ml), fruit length (40.20 mm), fruit diameter (35.25 mm), stone weight (1.11 g), stone thickness (7.23 mm) and shelf life (9.77 days) were noted in plum cultivar D-Agen. However, the maximum fruit diameter (49.39 mm) was recorded in fruits taken from cultivar Ruby red. While the highest total soluble solids (16.38 brix) were observed in D-agen. Cultivar Blufre fruits were observed with the highest stone length (29.71 mm) and shelf life (23.78 days). It could be inferred from the current findings that plum cultivar President should be grown under the agro climatic conditions of district Swat for good quality fruit production.

Varieties Azarbaijan and Earleeg showed significantly maximum number of leaves per cutting (65.88 and 64.55 respectively) and shoot length (18.21 and 17.88 cm respectively). Variety Azarbaijan gave significantly higher sprouting percentage (48.66%) and the number of shoots per cutting (4.88) followed by variety Earleeg with 35.55% sprouting and 3088 number of leaves per cutting. The shoot diameters were not significantly different in either variety. It can be concluded from the results that variety Azarbaijan gave the best performance followed by Earleeg in the agro-climatic conditions of Peshawar as regards the cutting performance is concerned.

Means for peroxide and acid value of olive oil were significantly influenced by cultivars and locations. The cultivar Coratina had the highest peroxide (18.50 milli eq/kg) and acid value (2.65%). By contrast, the least peroxide value (12.75milli eq/kg) and acid value (2.49%) was recorded in oil extracted from cultivars Pengalino and Leccino respectively. The interaction of olive cultivars and location of production revealed significant influence on both the two parameters under study. The peroxide value which was lower in oil of cultivars Leccino and Coratina (7.53 and 9.80 milli eq/kg respectively) but increased to 23.11 and 27.21 milli eq/kg in oil obtained from Chakwal location. While the peroxide value of cultivar Pendallino was not affected significantly. The acid value of olive oil was the least (0.85%) in cultivar Leccino and the highest (2.89%) in Pengalino at Sangbhatti farm.

Results revealed that different sowing dates, Ca, B treatments and their interaction significantly affected yield and quality parameters of potato crop. The application of Ca alone @ 0.06% significantly increased the large tubers plant−1 (2.0), total yield (18.6 t ha−1), survival (78%), dry matter content (18.3%) and starch content (14.6%) as compared to control treatment. Boron @ 0.04% also significantly enhanced large tubers plant−1 (2.1), total yield (18.7 t ha−1), survival (75%), dry matter content (18.2%) and starch content (14.9%) than control treatment. Foliar application of (0.06% Ca) + (0.02% B) resulted in the maximum number of large tubers plant−1 (2.5), total yield (20.5 t ha−1), dry matter content (19.5%) and starch content (16.2%) as compared to other treatment combination. Plant survival was maximum at (0.06% Ca) + (0.04% B). Increasing Ca, B concentration decreased in number of small size tubers plant−1. Early sown potato plants with the combined application of 0.06% Ca + 0.02% B resulted in maximum yield and quality characteristics as compared to the rest. So it is concluded that early planting in the first week of October with the combined application of 0.06% Ca + 0.02% B resulted in maximum yield and quality of potato.

As it is so popular, Olive can play an important role in the economy of a country and thus best practices can increase production per plant. Therefore, an attempt has been made to test the effect of three grafting times (June, July and August) and olive cultivars (Frantoio, Moresca, Biancolella and Leccino) on the production of Italian olives. The study was carried out at Agriculture Research Institute Tarnab, Peshawar-Pakistan during the summer of 2012. The various growth parameters (such as, sprouting percentage, number of sprouts, sprout length, number of leaves and days to sprout) were recorded from the time after grafting. The highest number of sprouts, sprouting percentage and days to sprout was observed in plants grafted in July, whereas, the maximum length of sprouts and leaves per sprout was noticed in plants grafted in June. Plants of Biancolell...

On an average, 15.5 alleles were amplified using Randomly Amplified Polymorphic DNA (RAPD) molecular primers. Mean genetic distance estimates ranged from 0.158 to 0.512 (G.D = 15.8 to 51.2%). Size of scorable fragments ranged from approximately 250 to >2000 bp. A high level of genetic dissimilarity (GD= up to 51%) was recorded among Ferugenia genotype only. Entries were grouped in clusters using cluster analysis. On the basis of dendrogram, most diverse genotypes Ferugenia and Coratina were identified, that can be used in future olive propagation program.
