Okra variety Sabzpari was shown on 10 th , 28 th February and 20 th March 2011. Weekly observations were taken on Bemisia tabaci population. Meteorological record was obtained from Meteorological Record Center, Sindh Horticulture Research Institute, Mirpur Khas.The results showed that the crop sown on 10 th February had one population peak of whitefly (5.00 ± 0.75 per leaf). The fluctuation in the population of whitefly was observed throughout cropping season on okra sown on 28 th February. Two peaks in population were recorded i.e. 1 st peak (6.04 ± 0.62, whitefly per leaf) in 4 th week of March and 2 nd peak (7.72 ± 1.08) in 3 rd week of April. The okra crop sown on 20 th March showed three population peaks of whitefly i.e. (7.42 ± 0.94 per leaf in 2 nd week of April), (8.46 ± 1.04 in 1 st week of May) and (5.98 ± 1.01 in the end of 2 nd week of June). The overall mean populations record were 1.76 ± 0.31, 2.73 ± 0.55 and 3.37 ± 0.61 on the crops sown on 10 th , 28 th February and 20 th March, respectively. The regression analysis showed significant negative correlation of whitefly population with temperature 0 C and relative humidity percent.

Cotton leaves and fruiting bodies were artificially terminated at 12, 24, 36, 48 and 60% and plant remained as such were treated with each of three growth regulators (Pix, Plano fix and Salicylic Acid), Micronutrients (Bigsaver, Dawn and Agrofeed) and insecticides (Confidor, Mospilan and Tracer) at their recommended doses. The experiment was laid out in a three replicated RCBD (Factorial arrangements). The result showed that the population of sucking insect pests as well as growth and seed cotton yield differed significantly between the treatments of plant parts termination, plant growth regulators, micronutrients and insecticides respectively. However, their interactions were statistically non-significant. Leaves and fruiting bodies removed resulted in lower infestation of sucking insect pests as compared to those remained as such. However, application of Pix resulted (PGR) reduced pest infestation as compared to Planofix and Salicylic acid and gave more number of bolls, and seed cotton yield. Similarly, foliar spray of micronutrients also reduced the infestation of pest and gave more bolls, boll diameter and seed cotton yield, Bigsaver was relatively more effective than Dawn and Agrofeed. However, application of insecticides decreased the damage of sucking pest resulted in greater boll number, boll diameter and seed cotton yield. Among the insecticides tested Confidor proved more effective in reducing pest as compared to Mospilan and Tracer. The mean population of Thrip was 0.15-3.93, Jassid 0.10-0.98, White fly 0.65-3.60 and of Aphid was 0.15-1.07. Thus it was found that termination of leaves and fruiting parts up to 60% compensate of the applied PGR and micronutrients beside application of insecticide.

Survey of cotton and other crop fields in Tandojam at weekly intervals from July 17 to 1 st September was done and the data on population of mealybug was recorded. It was found that on average the population of mealybug on cotton was 11.34 / twig (2") per plant, beside other 13 host plants were observed i.e. Abutilon (89.42), okra (16.06), China rose (1.39), Akson (2.86), Dhatura (1.24), Lantana (0.96), Brinjal (1.84), Ubat kandri (2.16), Itsit (2.19), sesame (290.26), Bleebooty (420.12) and Savri (101.17). It was found that the population of mealybug was higher on all plants during the month of August. The correlation carried out between mealybug population and temperature was negative and significant in cotton (r=-0.433), Abutilon (r=-0.585), Okra (r=-0.532), China rose (r=-0.315), Akson (r=-0.360), Dhatura (r=-0.529), Lantana (r=-0.498), Ubat kandri (r=-0.522), Itsit (r=-0.397), Sesame (r=-0.742), while negative and non-significant in Brinjal (r=-0.242), Bleebooty (r=-0.125) and Savri (r=-0.125) and Savri (r=-0.031). Further, it was found that the correlation of mealybug with relative humidity was positive and significant in Abutilon (r=0.321), Lantana (r=0.301) and sesame (r=0.471). However, positive and nonsignificant in case of cotton (r=0.108), Okra (r=0.195), Akson (r=0.194), Dhatura (r=0.226), Brinjal (r=0.290), Ubat kandri (0.257), Itsit (r=0.220), Bleebooty (r=0.173) and Savri (r=0.034).

Hybrid maize seed "Hycorn-984" was cultivated for this study, feed and fodder / grazing of the husbandry animals of the University. The experiment was laid out in a half acre plot which was equally divided into four sub-plots using Randomized Complete Block Design (RCBD) to facilitate the crop management. The results revealed that, the overall seasonal mean population of thrips observed was (5.69) followed by Black aphid (4.17), Leaf stem borer (0.61), Leaf aphid (0.96), Shoot fly (0.08) /plant. In case of predators, the Big eyed bug was recorded (1.27) followed by seven spotted ladybird beetle (0.44), Zigzag beetle (0.69), eleven spotted beetle (0.07), Brumus (0.50), Green lacewing (0.78) /plant, respectively. The correlation (r) studies showed that the population of thrips, black aphid was negatively corre...

The experiment was designed in Randomized Com plete Block Design (RCBD) with four tre atments and three replications. The insecticides Radiant, Crown and Finvil were applied thrice at the interval of 15 and 21 days of second and third spray respectively. The results showed that all three insecticides perform ed well in reducing pest population. However, Radiant gave best results against pea thrips, Calothrip indicus. The overall mean population per leaf 7.33, 8.78 and 10.23 of Caliothrips indicus was recorded in the plots treated with Radiant, Crown and Finvil, respectively as compared to control plot (12.13 thrips per leaf) during the first spray. During second spray the overall mean population per leaf 7.04, 8.02 and 8.97 of thrip was rec...

In order to see the effects of marginal quality ground water in comparison to good quality water (tap water) on crop yield and water use efficiency. Okra was grown under drip system of irrigation during the year, 2011. The soil characteristics, soil samples at depth of 0-15, 15-30 and 30-60 cm were drawn and analyzed in laboratory for various parameters. The results indicated that the soil under study was sandy loam in texture, having the DBD 1.59 gm/cm 3 , infiltration rate 1.56 cm/hr, F.C, W.P and A.M was 14.8, 6.2 and 8.6%, respectively. Before crop sowing, drip irrigation system was installed to assess for its performance through Uniformity Co-efficient which ranged from 93 to 96% and indicated that the system was working satisfactorily. The quantity of tap and ground water applied through drip system to okra crop was of equal volume i.e., 6989.7m3/ha. However, higher crop yield and highe...
