Abstract
The present investigation entitled “study on plant geometry, cultivar and fertilizer doses on growth, yield and quality of cucumber (cucumis sativus L.) under protected condition” conducted during winter season 2017-18 and 2018-19 was carried out at Vegetable Research Farm SHUATS, Prayagraj (Allahabad) U.P. Factorial RBD with three replications. In this way, the experiments were comprising of total twenty seven treatment combinations of three cultivars namely, Pant Parthenocarpic Cucumber 2 (V1), Pant Parthenocarpic Cucumber 3 (V2) and Hilton (V3). Three plant geometry i.e. 60 x 30 cm (P1), 60 x 40 cm (P2) and 60 x 50 cm (P3) and three NPK, fertilizers doses like, 20:10:22 kg/1000m2 (D1), 25:15:27 kg/1000m2 (D2) and 30:20:32 kg/1000m2 (D3). The fertilizers dose applies at twice a week. Similar treatments were applied during both the year.
The results revealed that all the treatments and their combinations had significantly influenced the growth, yield and quality of fruits during both the year of experimentation.Among the different cultivars used in the study, Pant Parthenocarpic Cucumber 3(V2). were found statistically superior to enhance vine length (2.73 m) stem girth (0.80 cm ) leaf area (412.34 cm2 ) Internodal distance (8.38 cm) minimum days required to first flower bud initiation (42.14 DAS), days to first fruit harvest (55.42 DAS), number of fruits per vine (21.89 ), number of unmarketable fruits per plants (1.46) average weight of fruit (116.41 g), fruit length (18.35 cm) and fruit width (3.45 cm) which ultimately gave maximum yield per vine (2.82 kg per plant) during pooled , respectively. Further, among the various spacing treatments, spacing (P3) 60 x 50 cm was found to be significantly superior with respect to vegetative growth, yield per plant and quality of fruits except yield per sq. meter in both the year .Significantly higher yield per sq. meter was recorded in spacing P1 (60 x 30 cm) and least in P3 (60 x 50 cm) during both the year. In case of dose of fertilizer application, the application of fertilizers through manually apply the root zone of plant was found superior to maximum fertilizers apply compared to minimum fertilizers apply during both the year. Maximum number of fruits per vine, average fruit weight (g), yield per vine (kg) and yield per sq. meter (kg) were recorded in both the year maximum fertilizers apply in

D3 maximum nutrient content in the leaf as total nitrogen (3.66 %), total phosphorus (0.83 %) and total potassium (2.44 %) along with minimum nutrient residues in the soil after harvest were recorded in maximum NPK combination apply to minimum fertilizer apply both the year, respectively. Therefore, it is recommended that cucumber should be grown at a spacing of 60 x 50 cm along with D3 NPK dose using cultivars (Pant Parthenocarpic Cucumber 3) during the winter season for sustaining higher fruit yield and quality cucumber under polyhouse condition. Whereas, on the basis of benefit cost ratio it could be recommended that cucumber cultivar 'Pant Parthenocarpic Cucumber 3' should be grown at a spacing of 60 x 50 cm along with the maximum NPK dose of fertilizers apply during both the year for attaining the maximum production of cucumber polyhouse condition.
