ABSTRACT

Oat (Avena sativa L.) is an important fodder crop. Phosphorus unavailability is one of the major limiting factors in getting its higher yield. Phosphorus availability can be enhanced with the application of phosphorus solubilizing bacteria and it may be helpful in increasing forage yield and improving quality of oat. Therefore, a field trial to evaluate the effect of phosphorus solubilizing bacterial inoculation and phosphorus application on forage yield and quality of oat was conducted at Agronomic Research Area, University of Agriculture, Faisalabad. The phosphorus was applied at the rate of 0, 30, 60 and 90 kg ha-1 to oat crop raised from inoculated and uninoculated seed. The crop was sown on December 1st, 2011 by using single row hand drill in 20 cm apart rows. The experiment was laid out in RCBD with factorial arrangement using three replications. The size of net plot was kept 1.8 m 6 m. Phosphorus application significantly affected the plant height, number of tiller m-2, number of leaves tiller-1, leaf area tiller-1, leaf to stem ratio, green forage yield, dry matter yield, dry matter %, crude protein %, fat content, crude fiber % and ash % of oat. Phosphorus solubilizing bacterial inoculation also significantly affected all the recorded parameters of oat. The interaction between phosphorus application and phosphorus solubilizing bacterial inoculation was significant only for leaf area tiller-1. FULL TEXT PDF

 ABSTRACT

 The present studies aimed to explore the relationship among different yield and quality traits in cross combinations LRA-5166 LSS, ARIZONA QUEEN LRA-5166 and MNH-512 LRA-5166 designated as cross 1, cross 2 and cross 3 respectively. Plant hieght (PH) had positive correlation with sympodia branches (SB), monopodial branches (MP) and bolls per plant (BPP), in all the three crosses but it had positive association with Ginning out turn (GOT%) in cross 2 and 3 with SL in cross 2, with FS in the cross 3, and it showed a negative association with FF and SL only in the cross 3. SB had a positive association with MB, NB and GOT% in all the three crosses while it had a positive relationship with FS in crosses 1 and 3 and with SL in crosses 1 and 2. SB had negative correlation with FF in cross 1. BPP had a positive correlation with FS in crosses 1 and 3. FF had positive correlation with FS in cross 3. FF negatively correlated with FS in crosses 1 and 2. GOT% had positive correlation with SL in crosses 1 and 2 and with the FS in crosses 1 and 3. All three crosses had the potential to be used in the development of high yielding varieties possessing good fiber quality traits. FULL TEXT PDF

ABSTRACT

 

Seven F2 populations of (Triticum aestivum L) obtained from cross combinations  Lasani-2008 Iqbal-2000, Lasani-2008 9432, Lasani-2008 9436, Lasani-2008 9444, Iqbal-2000 Lasani-2008, Iqbal-2000 9432 and Iqbal-2000 9436 involving six varieties / lines were studied to determine the broad-sense heritability and genetic advance  for plant height, days to heading, days to maturity, number of tillers per plant, flag leaf area, peduncle length and grain yield per plant. The broad-sense heritability estimates ranged from 16.24-66.62, 69.40-62.73, 61.68-91.18, 15.96-75.30, 23.37-74.43, 59.73- 93.22 and 8.19-78.86% respectively. The genetic advance estimates for plant height and days to heading varies from 0.62 - 4.64 and 3.65-8.02 respectively. While the genetic advance values ranged from 2.68-8.82, 0.43-3.50, 1.02-4.20, 0.30-6 and 2.86-8.82 for number of tillers per plant, flag leaf area, peduncle length, grain yield per plant and days to maturity respectively. The cross Lasani-2008 Iqbal-2000, Lasani-2008 9432 appeared to be most promising segregating material. FULL TEXT PDF

ABSTRACT

Gladiolus is a popular cut flower, both with the consumer and the florist alike because of its many spike forms, colors and color combinations. Four exotic cultivars of Gladiolus alatus viz., Madriver, Fado, Florared and Pietmohlen were evaluated for their performance under Rainfed conditions in the experimental area of the Department of Horticulture, Pir Mehr Ali Shah Arid Agriculture University Rawalpindi. Results showed that all gladiolus cultivars had significant effect on vegetative and floral characters. Among these cultivars Pietmohlen was promising for leaf length (cm), leaf area (cm2), days taken to start blooming, number of florets per plant and florets length. Florared showed superiority for number of leaves per plants and vase life. Pietmohlen and Florared performed better than Fado and Madriver in regards to vegetative and floral characteristics. Hence these two cultivars are recommended for general cultivation under conditions. FULL TEXT PDF

 ABSTRACT

 

The experiment was conducted at the research area of Oilseed Research Institute, Faisalabad to study the association analysis for yield and its characters in 30 linseed genotypes. The genotypic and phenotypic correlation coefficient obtained between different traits was similar in direction, while in magnitude, genotypic correlation was higher than the corresponding phenotypic correlations. Traits like number of seeds Capsule-1, number of capsules plant-1, number of branches plant-1, 1000 seed weight and had the strong positive association with seed yield. Path coefficient analysis revealed that direct and indirect effects of genotypic path coefficients were higher in magnitude than the corresponding phenotypic path coefficients. Number of capsules per plant showed a high and positive direct effect on seed yield. FULL TEXT PDF
