 Abstract

A pot experiment to evaluate the effect of different harvesting times on forage yield and quality attributes of different maize (Zea mays L.) cultivars was conducted at College of Agriculture, Dera Ghazi Khan during summer season, 2011. Seeds of cultivars viz. “Pak-Afgoi”, “Neelam”, “Cargil”, “Goldan” and “Akbar” were  sown manually on 20th July and each cultivar was harvested at 30, 45 and 60 days after sowing (DAS). The study was done under completely randomized design with factorial arrangement having three replications. Different cultivars and harvesting times significantly affected the growth, forage and dry weight per plant of maize. The growth and yield per plant of each cultivars significantly increased with the delay in harvesting times. Quality parameters like crude protein, crude fibre and total ash percentage were also significantly influenced by different cultivars and harvesting times. The crude protein contents of all cultivars decreased with the increase in harvesting timings, while the crude fibre and total ash percentage increased with the delay in harvesting times. It is concluded that delaying the harvesting up to 60 DAS, increased the green forage and dry weight per plant but decreased the forage quality. FULL TEXT PDF

 Abstract

Phosphorus is one of the primary nutrients for plants which influence their yield and quality. Effect of inoculation with phosphorous solubilizing bacteria and different levels of phosphorous application on fodder yield, growth and quality of maize was evaluated in a field experiment at Agronomy Research Area, University of Agriculture, Faisalabad in the month of February, 2012. The experiment comprised of phosphorous levels as 24, 36, 48 and 60 kg ha-1and seed inoculation with phosphorous solubilizing bacteria keeping un-inoculated seeds as control treatment. The experiment was laid out in RCBD with factorial arrangement using three replications. The application of phosphorous significantly improved the growth, yield and quality of maize forage. The maximum green forage yield (63.15 t ha-1) was recorded with phosphors @ 60 kg ha-1. Seed inoculation had a significant influence on plant height, leaf area per plant, stem diameter, fresh weight per plant and forage yield. The maximum green forage yield (58.10 t ha-1) was obtained when seeds were inoculated with Azosprillum spp. Phosphorus application at the rate of 60 kg ha-1 to maize crop raised from inoculated seed with phosphorus solubilizing microbial inoculation seems to be the optimum dose for obtaining higher maize forage yield having good quality.

Abstract

Twenty genotypes of safflower was evaluated to study the genotypic and phenotypic correlation coefficients and path effects of yield related traits on grain yield during rabi cropping season 2011-12 at Barani Agricultural Research Institute, Chakwal, Pakistan. Grain yield (kg/ha) correlated significantly and positively with plant height, boll diameter, number of grains per boll, 1000 grain weight and days to maturity. Thus these characters are the key yield contributing attributes to be given selection pressure for improving yield. The result of path analysis showed highest and positive direct effect of number of grains per boll followed by 1000 grain weight and plant height on grain yield (kg/ha). FULL TEXT PDF

Abstract

Fertilizer is a vital input for food production and it should be used efficiently in order to minimize food production cost as well as to conserve natural resources. In developing countries crop yield are low either due to the lack of fertilizer or inefficient use of fertilizers. In Pakistan, the response of crop to applied K is unpredictable due to lack of refined critical level of soil K and this unpredictability is further intensified due to different adsorption characteristics of various soils for K. As fertilizer the fate of added K depends upon the initial level of soil K. The concentration of K in soil solution depend on the rapidity at which desorption of K can be occurred from the adsorption phase and the rate of removal by the plants, whereas adsorption equilibrium solution K level serve as a key of K availability. The response of crops to K considerably depends on the original status of the K, the status of initial soil K concentration must be considered before K fertilizer application. In the Indus plain of Pakistan, soils contain 2.65 to 3.55 % K. in the surveyed area of Pakistan more than half of the soils are categorized as Aridisols, under this situation crop response to K fertilizer are very unbalanced and intermittent because scientifically based critical soil K level did not exist.

Abstract

A field experiment was carried out to determine forage yield and quality response of oat cultivars to different sowing techniques at Agronomic Research Area, University of Agriculture, Faisalabad during winter season 2012. The experiment was laid out in randomized complete block design (RCBD) with factorial arrangement replicated three (3) times. The net plot size was kept 5m x1.6 m. The treatments were three varieties viz., Kalash, F-414 and CK-1of oat sown with three different sowing techniques i.e. broadcast, 20 cm apart single rows and 30 cm apart double row strips.The growth, yield and quality parameters differed significantly (P<0.05) among the different cultivars and sowing techniques. The maximum values for germination counts m-2 (226.43), plant population m-2 (150.33), plant height (145.37 cm), number of tillers plant-1 (7.93) , leaf area per tiller (163.47 cm2), fresh weight plant-1 (28.46 g), dry weight plant-1 (8.70 g), green forage yield (82.97 t ha-1), dry matter  yield (13.40 t ha-1), crude protein ( 10.27 %) , crude fibre (33.97%)  and total ash contents (9.93%) were observed in 20 cm apart single rows. Among the varieties, CK-1 also proved best for above mentioned parameters. Number of leaves per tiller was the only parameter not influenced significantly by sowing techniques.FULL TEXT PDF
