sA laboratory Experiment was carried out to determine the physic-chemical composition of Red Delicious and Amri apple varieties under fresh and stored condition, which were determined on October 30, November 30, and December 30. The physical and chemical characteristics determined were, fruit length and diameter, single fruit weight, juice percentage, total soluble solids (TSS), acidity percentage, ascorbic acid, reducing and non-reducing sugar percentage. It is obvious from the results that the varieties had significant differences for fruit length, fruit diameter and single fruit weight. Juice percentage remained unaffected due to varieties. Variety Red Delicious was considered to be better in physical properties when its comparison was made with variety Amri. Observation intervals had significant effect on fruit length and juice percentage, while fruit diameter and single fruit weight remained unaffected. The result mean interval of Red Delicious observations TSS % (14.29), Acidity % (0.42), Ascorbic acid (5.61), Reducing sugar % (7.08) and Non-reducing sugar % (2.54) was obtained as compare to variety Amri the result mean interval TSS % (14.21), Acidity % (0.36), Ascorbic acid (4.43Mg), Reducing sugar % (6.81) and Non-reducing sugar % (4.08) was obtained. The result illustrated that for chemical analysis varieties had significant effect on acidity percentage, ascorbic acid and non-reducing sugars, while T.S.S and reducing sugars remained unaffected due to different varieties. All the chemical properties i.e. T.S.S, acidity, ascorbic acid, reducing sugars and non-reducing sugars affected significantly by observation intervals.
In order to examine the growth and yield response of bitter gourd to foliar applied urea at different concentrations and irrigation at various frequencies, the experiment was conducted during 2016 using 3 replicated Randomized Complete Block Design at Sindh Agriculture University Tandojam. Irrigation was applied at weekly interval (T1), Irrigation at 10 days interval (T2), T2+foliar urea @ 1.5% (T3), T2+foliar urea @ 3% (T4), Irrigation at 15 days interval (T5), T5 + foliar urea @ 1.5% (T6), T5 + foliar urea @ 3% (T7). The results revealed that Irrigation at 10 days interval + foliar urea at 3.0% conc.proved to be an optimum treatmentand resulted in 144.95 cm vine length, 19.96 cm fruit length, 17.45cm diameter of fruit, 79.95 g average fruit weight, 8.95 number of fruits vine-1 , 739.00 g weight of fruits vine-1 and 9199.7 kg ha-1 fruit yield. The irrigation at 10 days interval + foliar application of urea (1.5%)ranked 2 nd ; irrigation at 15 days interval + foliar urea (3.0%)ranked 3 rd ; irrigation at 15 days interval + foliar urea (1.5%)ranked 4 th ; while weekly (control), 10 days,15 days irrigation interval without foliar applied urea ranked 5 th , 6 th and 7 th respectively. The values for all the growth and productivity of bitter gourd were markedly increased with foliar application of urea, particularly at higher concentration. It was concluded that for acghieving desired yield performance of bittergourd the crop may be irrigted at 10 days interval + foliar application of urea at 3.0% conc.
