  To explore N- use efficiency of MNH554 a tetraploid cotton (Gossvpium hirsutum L.) in relation to various irrigation regimes, a three year project was launched in 1998 under agro-ecological conditions prevailing at Multan. The experiment was seeded in the open field during the normal growing season, with pure and true to type seed of variety MNH554. Four nitrogen doses and three irrigations regimes were applied to the crop. In addition, the crop had also received 56 kg P ha-1 and 55 kg K ha-1 as a basal dose. Growth and development characteristics comprising of height of the plant, number of mature bolls per plant, boll weight, yield of seed cotton and ginning outturn were studied. Plant height, bolls per plant, boll weight and yield of seed cotton registered a positive and significant response to increasing doses of nitrogen and irrigation. On an average of three years, the maximum yield of 4105 kg ha-1 of seed cotton was obtained by 168 kg N ha-1 with seven irrigations, well distributed throughout the growth and development period. Nitrogen and irrigation application did not improve the ginning outturn, rather it ensued a slight drop.

  To investigate the effect of split application of nitrogen on cotton yield and its components for medium stapled commercial cotton (Gossypium hirsutum L.) variety MNH554, a field trial was carried out at Cotton Research Station, Multan during 1998 to 2000. Ten nitrogen levels viz., 0, 56, 84, 112, 112, 140, 168, 168, 196 and 224 kg N ha-1 were tested in Randomized Complete Block Design having three replications. Nitrogen was applied in split doses at planting. Ist irrigation, flowering and boll fermentation. 56 kg P2O2 ha-1 was also applied as a basal dose . N168 kg ha-1 proved superior over others when split applied in three equal doses i.e., 56, 56, 56 kg N ha-1 at Ist irrigation, flowering and boll formation stages. This produced a significant increase in plant height, bolls per plant, boll weight and seed cotton yield. On the average of three years 168 kg N ha-1 gave 212.8% increase in seed cotton yield over O.N.

  The objective of this study was to compare yield, yield components and fiber traits of different genotypes/varieties under different plant spacings and nitrogen fertilizer levels. Field experiment was conducted during 2006-2007 to evaluate the effect of genotype, plant spacing and nitrogen fertilizer on cotton. Five genotypes (MNH-786, MNH-789, MNH-6070, CIM-496 and BH-160), three plant spacings (15, 30 and 45 cm) and three nitrogen fertilizer levels (6.5, 8.6 and 11 bags of urea ha-1) were studied. Results showed that significant differences exit for plant height, no. of bolls m-2, seed cotton yield kg ha-1 due to genotypes, interaction of genotype and plant spacing and nitrogen fertilizer levels. Where as boll weight (B. wt.), Ginning out turn percentage (G.O.T %), staple length (SL) and fiber fineness were not affected significantly by the plant spacing, nitrogen fertilizer but effect due to genotype was significant for these traits. CLCuV (Cotton leaf curl virus) infestation % varied significantly due to genotypes while all other factors i.e., plant spacing and nitrogen fertilizer has non-significant effect. As the major objective of cotton cultivation is lint production for country and seed cotton yield for the farmers, the genotypes grown in narrow plant spacing 15 cm and higher nitrogen fertilizer level 11.0 bag of urea ha-1 produced maximum seed cotton yield under higher CLCuV infestation % (CIM-496, MNH-789 and BH-160) while the variety MNH-6070 gave maximum yield under 30 cm plant spacing and 8.6 bag of urea ha-1 as the 2.3% CLCuV infestation was observed upon this variety. From the present study it is concluded that the genotypes that are severally affected by CLCuV can be managed with increasing plant population and nitrogen fertilizer to achieve optimum seed cotton yield.

  Four varieties of onion viz; Phulkara Dark Red, Desi and Rubina were evaluated to see the effect of pollinator and insecticides on seed setting. Reduced or limited visiting of pollinators caused substantial reduction in seed production of onion showing 50 to 61% seed setting with non significant difference among the varieties. However significant differences were observed among varieties for number of flowers per umbel, number of fertilized flowers per umbel, umbel weight and seed weight per umbel. This reduction in seed production could be due to pesticides application of side grown crops (sunflower, brassica and coriander etc.).

  An experiment was conducted to assess the effect of sowing date on two cotton varieties MNH552 and MNH554 grown on Ist April, 15th April, Ist. May, 15th May, Ist. June, 15th June, Ist. July and 15th July during 1998 and 1999 under Multan conditions. 15th May and Ist June sown cotton displayed significantly maximum seed cotton yield of 2998 and 2883 kg ha-1 in 1998 and 4027 and 3894 kg ha-1 respectively in 1999 as compared to 595 and 253 kg ha-1 (1998) and 1269 and 223 kg ha-1 (1999) from crop sown on Ist and 15th July respectively. The increase in both sowing dates in seed cotton yield was associated with boll weight and bolls per plant. On average of two years data 15th May produced highest seed cotton yield of 3513 kg ha-1, whereas the lowest figure was 238 kg ha-1 (15th July). Comparing varietal performance MNH552 (2310 kg ha-1) yielded higher as compared to MNH554 (2288 kg ha-1). However two cultivars declined the yield in late planting.

  A wide range of average performance and genetic variability was estimated for F1 crosses of nine commercial varieties of cotton viz., CIM443, MNH147, FH-682, N. Krishma, SLS-1, CIM-446, CIM448, FVH-53 and MNH552 for bolls and seed cotton yield per plant, boll weight, staple length, ginning out turn (%) and virus infestation (%). The highest genotypic variability was recorded for virus infestation (94.61%) followed by bolls per plant (29.84%). The highest estimates of heritability associated with highest genetic advance for bolls per plant (97.8 and 60.78), virus infestation % (95.0 and 189.9) and boll weight (97.39 and 10.99) suggested selection for improvement of these traits due to presence of sufficient genotypic variability. However, low estimates of these parameters for staple length showed slow progress through selection.

Reduced or limited visiting of pollinators caused substantial reduction in seed production of onion showing 50 to 61% seed setting with non significant differences among the varieties. However, significant differences were observed among varieties for number of flowers, fertilized flowers, seed weight per umbel and umbel weight. This reduction in seed production could be due to pesticides application or attraction of side grown crops (Sunflower, Brassica and Coriander etc.)

  The study was conducted to evaluate the organic matter status of soil in the Kahuta tehsil from District Rawalpindi. Nintey composite soil samples were analysed for organic matter contents. Soil texture varied from sandy loam (Light) 20%, loam (Medium) 78% and Clay loam (Heavy) 2%. Organic matter was deficient in 100% soil samples.The maximum organic matter of 0.85% were recorded at Loona Kahuta site and minimum organic matter of 0.20% were observed at Kahuta and Dodheli site. The average maximum organic matter of 0.70% were observed at Loona Kahuta site. Fertilizer recommendations were given to farmers according to soil condition and organic matter status.
