Description The present investigations entitled “Studies on drip irrigation and fertigation in strawberry (Fragaria x ananassa Duch.)” were conducted during 2010 to 2012 at the experimental farm of the department of
Fruit Science, Dr.Y.S.Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.). The study consisted of two experiments. In irrigation trial, five irrigation treatments viz., drip irrigation at 120, 100, 80 and 60% ETc and furrow irrigation with ‘V’ volume were tried out in a Randomized Block Design and each treatment was replicated five times. Healthy runners of ‘Chandler’ variety were planted at a spacing of 25x50 cm in the last week of September. The results revealed that drip irrigation at 120% ETc and 100% ETc significantly increased vegetative growth, yield, quality and physiological parameters in strawberry as compared to that of furrow irrigation. The maximum vegetative growth, yield, fruit size, photosynthetic and transpiration rate were recorded in drip irrigation at 120%. The leaf nutrients content (N, P, K, Ca, Mg, Mn, Zn, Cu and Fe) were also found higher in the plants, which were irrigated with 120% ETc through drip irrigation. The maximum water use efficiency was recorded in drip irrigation at 60% ETc and minimum in furrow irrigation with ‘V’ volume of water. The higher soil moisture content was recorded in drip irrigation at 120% ETc throughout the cropping season as compared to that of furrow irrigation. In fertigation trial, five fertilization treatments viz., recommended dose of NPK through soil, recommended
dose of NPK through drip, 3/4th of recommended dose of NPK through drip, 1/2 of recommended dose of NPK through drip and 1/3rd of recommended dose of NPK through drip were tried and each treatment was replicated five times in Randomized Block Design. Fertigation significantly increased the vegetative growth, yield and quality parameters of strawberry as compared to traditional soil application of fertilizers. The maximum vegetative growth in terms of plant height, number of leaves, leaf area and number of runners was recorded in plants fertigated with recommended dose of NPK fertilizers. The fruit yield, size, weight and quality of fruits were significantly higher under fertigation with recommended dose of NPK and 3/4th of recommended dose of NPK as compared to that of soil fertilization. The leaf and soil nutrients content were significantly higher under fertigation with recommended dose and 3/4th of recommended dose of NPK fertilizers. Fertilizer use efficiency was also higher under fertigation as compared to soil application.
