Effect of planting dates and agricultural media on some yield characteristics of strawberry cv. Festival under Green House condition

Abstract

The study was done inunwarmed plastic house of Department of Horticulture and Garden Engineering, Agriculture college, University Baghdad the alternative location University of Al−Anbar to study the effect of planting dates and agricultural media and their interactions on some yield characteristics of strawberry (cultivar festival) for of 2016−2017 seasons. The study included 12 treatments represented the interactions of three planting dates (16/10/2016, 3/11/2016 and 21/11/2016) named D1,D2 and D3 respectively, and four mixtures 100% sandy loam soil (control medium), sandy loam soil with peatmoss and composted sheep manure, sandy loam soil with peatmoss and composted calf manure, sandy loam soil with peatmoss and composted poultry manure in the ratios of (2:1:1) respectively These named M0, M1, M2 and M3 respectively. The experimental design was conducted according to Randomized completely block design (R.C.B.D) with three Replicates, the means were compared using the test is less significant difference (L.S.D) and the level of 5% probability. The results showed the superiority of early planting in the first planting date since it recorded the highest averages in percentage of fruit dry matter، T.S.S ratio، acidity ratio (TA) ، and amount of vitamin C reached (7.53%, 7.06%, 0.75% and 52.42 mg.100 ml−1) respectively، while the second planting date gave the highest average for TA:T.S.S ratio (9.34). in conclusion, planting with soil mixture contain organic supplements led to significantly increment in most yield parameters comparing with the control (M0).
