Abstract:
An investigation was conducted at experimental field, Division of Vegetable Science, SKUAST-Kashmir in 2019 and 2020 to study “Influence of fertigation and pruning levels on soil status and mineral content of parthenocarpic cucumber under polyhouse conditions”. The experiment was laid out in RCBD with three replications comprising of two factors with 2 levels of pruning (P) viz., P₀ (control or no pruning), P₁ (Single stem system) and 6 levels of fertigation (F) viz., F₀ (control or no fertigation), F₁ (100:75:125 NPK kg ha^-1), F₂ (150:112:188 NPK kg ha^-1), F₃ (200:150:250 NPK kg ha^-1), F₄ (250:188:312 NPK kg ha^-1) and F₅ (300:225:375 NPK 1.500 kg ha^-1). The observations were recorded on mineral content, availability of nutrients and soil properties. Significantly maximum value of N, P, K, Ca, Mn, Zn and Fe contents were observed in plants pruned with single system as compared to the plants with no pruning. In case of fertigation F₄ recorded maximum values while among treatment combination F₄P₁ has given maximum values of nutrient content. It was observed that neither pruning nor interaction between pruning and fertigation levels has not any significant effect on availability of nutrients. However, effect of different levels of fertigation on availability of N, P and K was found significant. Significantly higher values of available P (18.69kg ha^-1) and K (177.8 kg ha-¹) in F₄, but available nitrogen was observed maximum in F₅.
