 Abstract

This experiment was carried out to elucidate the gene action controlling the inheritance of some quantitative traits like days to heading, days to maturity, plant height, number of tillers per plant, peduncle length and flag leaf area using 5×5 diallel cross. The wheat lines/varieties were 9272, 9277, 9381, Lasani-2008 and Sehar-2006. Days to heading, plant height and number of tillers per plant were under the influence of partial dominance. However, peduncle length and flag leaf area were controlled by partial dominance with additive type of gene action indicating early selection for improvement in these parameters, while over dominance was recorded for days to maturity suggested fruitful selection in later generations.

Abstract

Egypt leads the world in date fruit production. ‘Zaghloul’ date is a popular soft date in Egypt. It is an early season cultivar that is extensively cultivated in the North Delta region, an important region for soft date production in Egypt. Bagging of inflorescences is a physical technique commonly used with many crops to both protect fruits from diseases and pests and to alter the microenvironment of fruits development. The microenvironment exerts multiple effects on fruit growth and quality. Bagged and unbagged fruits were evaluated for fruit quality during the hababok, kimeri and khelal stages of fruit development. Inflorescences were bagged immediately after pollination and remained bagged for 35 days. Bagging modified the microenvironment of the fruit, increasing humidity, this remained above 70% between two and three weeks after bagging. Bagging also increased temperature around the inflorescences and promoted fruit development, increased the final fruit retention percentage, and improved fruit yield and quality (both physical and chemical characteristics), especially during the kimeri and khelal stages. Based on the results, bagging inflorescences after pollination is recommended as a pre-harvest treatment to promote early ripening and improve fruit quality of Zaghloul date palms.

Abstract

Exogenous application of amino acids as phytohormones’ precursors is a good approach in enhancing crops growth and development as it ensures continuous supply of phytohormones through microbial conversion. Response of exogenous application of L-Tryptophan, a precursor of auxin, was evaluated on the growth and yield of chilli through a pot experiment. The treatments comprising of varying concentrations of L-Tryptophan (10-6 M, 10-5 M, 10-4 M and 10-3 M) were arranged following Completely Randomized Design (CRD) with four replications. Plants moisture contents were maintained by the application of distilled water. The results obtained were statistically analyzed and pronounced effects of L-Tryptophan application was observed on all the growth and yield parameters. Among the treatments applied, the maximum results were recorded at 10-5 M L-TRP and it increased plant height (23.51%), shoot dry weight (34.83%), root dry weight (39.53%), fruit weight (43.37%), number of fruits (48.65%), number of leaves (29.25%), fruit length (44.52%), root length (47.13%) chlorophyll contents (25.48%), concentration of N (46.25%), P (11.46%) and K (28.01%) in fruits as compared to control. The results suggested that application of L-Tryptophan is better for improved plants growth and development.

Abstract

A field experiment was conducted to study the quantitative and qualitative response of maize (Zea mays L.) to irrigation levels and organic mulches during Autumn 2012. The experiment was conducted at Agronomic research area, University of Agriculture, Faisalabad. Randomized Complete Block Design (RCBD) with split plot arrangement was used to layout the experiment comprising three replications. Three irrigation levels I1 (3 irrigations), I2 (5 irrigations) and I3 (7 irrigations) were kept in main plots and applied at different growth stages of the maize. Three mulching treatments M0 (control), M1 (maize straw) and M2 (grass clippings) were applied to the soil after sowing. The data regarding growth, yield and quality parameters of maize were recorded by using standard procedures. The data was statistically analyzed by applying Fisher’s analysis of variances technique. The results on different parameters showed that the combination (7 irrigations and maize stalk mulch) was attributed with the maximum maize 1000-grain weight (280.27 g), grain yield (5.80 t ha-1) and biological yield (15.21 t ha-1). Irrigation levels and organic mulches also significantly affected the interaction effect of 1000-grain weight, grain yield, biological yield and harvest index. The data on quality parameters revealed that both irrigation levels and mulching materials significantly increased the seed protein and oil content (11.08% and 5.23%) , respectively as compared to control. The study concluded that maize stalk mulch applied with 7 irrigations enhanced growth and yield of the crop, improved the quality content of the maize grains as well improved soil physical condition.

 Abstract

Pot experiment was carried out at the Henfaes Research Centre, University of Wales, Bangor, UK to compare forage yield and quality of perennial wheat genotypes namely AGCS, MT2 Spitzer, SS259, V550713  and V550715 harvested twice. The genotypes varied significantly for yield and yield components and quality parameters. The genotype MT2 produced higher forage and dry matter yield due to greater plant height and tillers per pot. The Spitzer was superior in quality regarding crude protein, ash percentage and digestible dry matter percentage. However, modified acid detergent fiber was the minimum in V550713. Though forage yield was higher in September cut, but was of poor quality compared with December cut. The genotype MT2 also performed better in the December cuts regarding forage yield due to better sprouting potential. Keeping in view the findings of present study, the genotype MT2 seems to be a better choice for forage production as its yield was higher in both the cuts.

Abstract

The present study was carried out in Agronomic Research Area, University of Agriculture, Faisalabad to evaluate the production potential of soybean (Glycine max L.) in response to boron. In this experiment the variety William-82 was sown in spring 2012. The treatments were comprised of seven levels of boron i.e. 0, 2, 4, 6, 8, 10 and 12 kg ha-1. Borax was used as boron source. The experiment was carried out in Randomized Complete Block Design (RCBD) using three replications. Boron at 2 kg ha-1 significantly increased plant height (60.94 cm), number of pods plant-1 (43.22), number of pods bearing branches (6.55), thousand seed weight (88.07 g), grain yield (1757 kg ha-1), biological yield (4122 kg ha-1), harvest index (42.62 %) and protein content (36.48 %) while maximum oil contents (20.67 %) were obtained when 8 kg ha-1 (B4) boron was used which was statistically at par with treatment 2 kg ha-1 (B1). While maximum net income was also obtained by application of boron at 2 kg ha-1 under agro ecological conditions of Pakistan.

 Abstract

Understanding the inheritance mechanism of yield and yield related traits is a prerequisite for genetic improvement of wheat. A total of 23 wheat genotypes including 14 F1 hybrids and 9 parents were grown under normal conditions in the field of Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad during crop season 2012-13. Combining ability analysis was used to calculate GCA and SCA effects. Plant height was controlled by non-additive gene action while fertile tillers per plant, spike length, spikelets per spike, number of grains per spike, grain weight per spike and yield per plant showed higher GCA effects than SCA indicating involvement of additive gene action in expression of these traits. Thousand grain weight was controlled by both additive and non-additive gene action. Association among the traits showed that number of fertile tillers per plant, grains per spike and grain weight per spike had more contribution in wheat grain yield.
