ABSTRACT.A field trial was carried out to examine the comparative efficacy of organic and inorganic sources of nitrogen and phosphorous fertilizers alone and in different combinations to find the yield and quality contributing factors of oat (Avena sativa L.) during 2008-09 at Agronomic Research Area, University of Agriculture Faisalabad. The treatments were tested under randomized complete block design using three replications. Significant result were found in respect of plant height (146.3 cm), number of leaves per plant (6.87), number of tillers per plant (8.02), number of tillers m -2 (336), leaf area per plant (128 cm 2 ), fresh weight per tiller (30.10g), dry weight per tiller (5.01g) and green fodder yield (74.67 t ha -1 ) in contrast to organic manures and its combination with inorganic fertilizer (inorganic sources of manures). From the present study it can be concluded to meet the needs of fodder; it is better to use inorganic sources that are more effective and quick in response while organic sources are more environmental friendly than inorganic sources.

To examine the growth and radiation use efficiency (RUE) of different sugarcane cultivars (HSF 240, CP 77-400 & CPF 249) under two planting methods (2.5 feet apart single row, a farmers’ practice, and 4 feet apart dual rows deep trench plantings, a recommended practice) at Research Farm of Sugarcane Research Institute (SRI), Ayub Agricultural Research Institute (AARI), Faisalabad during 2019-20. The experiment was carried out in randomized complete block design with split-plot arrangement in three repeats. The results showed maximum dry matter (3348.24 g m-2), CGR (21.49 g m-2 day-1), mean CGR (12.78 g m-2 day-1), LAI (7.81), leaf area duration (1290.32 days), along with radiation use efficiency for total dry matter (2.16 g MJ-1) and cane yield (6.32 g MJ-1) in 4 feet apart dual rows trench planting in comparison to 2.5 feet apart single row trench planting, 2.08 g MJ-1 and 5.70 g MJ-1, respectively. On the other hand, higher dry matter (3451.42 g m-2), CGR (21.54 g m-2 day-1), mean CGR (13.16 g m-2 day-1), LAI (8.01), LAD (1324.58 days), RUE for dry matter production (2.20 g MJ-1) and cane yield (6.53 g MJ-1) was recorded in variety CP 77-400, a direct introduction to SRI, as compared with local material, HSF 240 and CPF 249 and occupying large area in whole Punjab-Pakistan.
