Description The present investigation was carried on “Effect of fertigation and mulching on growth, yield and quality (Carica papaya L.) cv. Red Lady” at Regional Horticulture Research Station, Navsari and Fruit Research Station, Gandevi, Navsari Agricultural University, Navsari during the year 2012-13. The laboratory
work was carried out at Department of Soil Science and Agril. Chemistry, ASPEE College of Horticulture and Forestry, Navasari Agricultureal University, Navsari-396 450.
The experiment was laid out in Randomized Block Design with factorial concept including twelve treatments and three replications. FYM (10 kg / pit) was applied as basal as per recommendation. Recommended dose of phosphoru s (200g / plant) was applied in two equal splits, first at 1 1 / 2 months and second at 3 months after transplanting. Nitrogen and potash applied in the form of urea and muriate of potash, respectively as per treatment, in 14 (S1 ) and 18 (S 2 ) splits equal dose starting form 45 and 15 days in mulch and without mulch treatments after transplanting, subsequently at 15 days intervals through drip irrigation. The observations on physiological attributes, growth characters, yield and quality parameters as well as nutrient status were recorded and analyzed statistically.
The growth parameters viz., plant height (cm), stem girth (stem diameter) (cm), number of leaves, length of petiole (cm) and total leaf area (m 2 ) were significantly recorded the maximum in papaya plant received F 1 (N and K2 O @ 100 % RDF) followed by F 2 (N and K 2 O @ 80 % RDF) and 18 splits (S 2 ) at 15 days intervals after fifteen days transplanting of seedlings at 180, 270 and 360 days after transplanting at both the places during the period of experimentation and in pooled analysis also. Whereas, F 1 (N and K2 O @ 100 % RDF) initiated earliness in flowering (days). Similar trend was also observed in physiological parameters like, photosynthetic rate and chlorophyll contents in leaf with maximum values under the treatment N and K2 O @ 100 % RDF (F 1 ) on 180, 270 and 360 days after transplanting, respectively. Leaf temperature was found non-significant. Number of fruits per tree, average fruit weight (kg), fruit diameter (cm), fruit yield (kg per plant and t per ha as well as quality parameters viz., total soluble solids (%), total sugar (%), reducing sugar (%), titrable acidity (%), shelf life (days) of fruit were found significant along with improvement in quality.
Looking to the nutrient status in papaya leaf was found effective at age 180 and 300 days in F
1 treatment i.e. N and K2 O @ 100 % RDF applied at 18 splits (S 2 ) through drip irrigation after fifteen days transplanting seedling during both the centres and in pooled study, respectively.
On the basis of results obtained in present investigation, it can be concluded that the highest net returns of 2.39 lacs/ha with BCR (1.98:1), when applied N and K 2 O @ 100 % RDF.
