Response of two sorghum cultivars namely Hegari and JS-263 to different NP levels of 0-0, 50-0, 100-0, 50-50, 100-50 and 100-100 kg haG 1 was studied under field conditions. The cultivar Hegari gave significantly higher green fodder and dry matter yield due to greater plant height, stem diameter and leaf area plantG 1. The crude fiber per cent and ash per cent were also significantly higher for cultivar Hegari. A progressive increase in yield was observed with fertilizer application up to 100 kg N + 50 kg P 2 0 5 haG 1 whereas, the quality parameters such as protein content, crude fiber and ash percent were significantly higher with NP application of 100 + 100 kg haG 1. The cultivar Hegari and fertilizer level of 100 kg N + 50 kg P 2 0 5 haG 1 seems to be the best combination for harvesting higher fodder yield of sorghum under Faisalabad conditions.

A total of 192, 14 days old as hatched broilers were fed ad libitum up to 56 days of age, on a control diet with 12% fish meal (FM) and 3 test diets; shrimp waste (SW) and/or marine waste (MW) and equal mixture of SW and MW completely replace dietary FM to have their effects on performance. Live weight and feed conversion improved and feed intake depleted on test diets than that on control. The test diets did not affect survivability of broilers. Complete replacement of FM by SW and/or MW reduced feed cost and production cost with increased profitability of raising broilers. Meat yield decreased on test SM and MW diets, but equal mixture of SM and MW, gave similar meat yield to that on control. It was concluded that equal mixture of SM and MW might be better, economic and efficient substitute of FM.DOI: http://dx.doi.org/10.3329/bjas.v40i1-2.10785Bang. J. Anim. Sci. 2011. 40 (1-2): 18-22

Yield contributing traits in thirty three rice genotypes were studied for variances, heritability, correlation (genotypic and phenotypic) and path coefficient analysis. The highest phenotypic variation (σ2p), was found for No. of grain per panicle and the lowest was observed in 100 grain wt. High genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) for No. of unfilled grains per panicle, No. of grains per panicle and grains yield per hill, indicated that selection of these traits would be effective. The high heritability estimates along with low genetic advance indicates that non-additive type of gene action and genotype-environment interaction plays a significant role in the expression of the traits as observed in days to 50% flowering, No. of tillers per hill days to harvesting and panicle length (cm). No. of grains per panicle with grains yield per hill as well as length showed significant and positive correlation but No. of tillers per hill showed highly significant and negative correlation with days to 50% flowering both at genotypic and phenotypic level. Path coefficient analysis showed that No. of grains per panicle had maximum direct effect on grain yield followed by No. of panicles per hill, and No. of tillers per hill. The lowest direct effect on grain yield was exhibited by No. of unfilled grains (0.0732) followed by plant height, No. of primary branches per panicles, and No. of secondary branches per panicles respectively. Number of grains per panicle had maximum direct effect on grain yield followed by No. of panicles per hill and No. of tillers per hill. The results prescribed that there is a highly significant positive correlation with positive direct effect was observed in No. of grains per panicle, No. of panicles per hill, No. of unfilled grains per panicle, No. of primary branches and No. of secondary branches.

Response of two sunflower cultivars namely Aritar-93 and suncom-110 to N levels of 0, 50, 100 and 150 kg haG 1 was studied under field conditions. Sunflower cultivar suncom-110 produced significantly higher plant height, leaf area per plant, 1000-achene weight and achene yield. Plant height, leaf per plant, stem diameter, no. of achenes per disc and achene protein contents were maximum at N level of 150 kg haG 1 . Whereas, oil contents were significantly higher in control. Nitrogen application at 100 and 150 kg haG 1 gave statistically similar achene yields of 15.95 and 16.18 q haG 1 respectively. Application of nitrogen more than 100 kg haG 1 seems to be uneconomical.
