Abstract
A field experiment was carried out in riverbed of Kanchanpur district to know the performance of cucumber varieties under different nutrients sources. The research site was facing the problem of low productivity of cucumber due to the use of indigenous variety and traditional cultivation practices. So the research was conducted to know the best variety of cucumber with different nutrients source under riverbed condition. The research was carried out from 13th December 2016 to 15th May 2017. The soil of experimental field was sandy loam with pH 6.2. The crop geometry was 75 cm×75cm and the size of each plot was 14.0625 m2. The research was carried out in RCBD design with 8 treatments and 3 replications. The treatment combination used for the field experiment were FYM + Ninja-179, FYM + Malini, Poultry manure + Ninja-179, Poultry manure + Malini, Oilseed cake + Ninja-179, Oilseed cake + Malini, NPK + Ninja-179 and NPK + Malini. Data were collected on the following parameters such as vine length, number of leaves, leaf length, leaf breadth, days to first flowering, days to first fruiting, days to first fruit maturity, male and female flower ratio fruit weight, fruit length, fruit diameter and fruit yield. It is revealed that the performance of different combination of treatments, NPK + Ninja-179 was found to be the best high yielding variety for this locality with yield of 68.79 ton/ha. Besides fruit yield, the treatment combination of NPK + Ninja-179 was superior to other treatment combination in others parameters like vine length(64.67 cm), number of leaves(17.93), fruit length(21.8 cm), fruit weight (535.31g) and fruit diameter(6.00 cm). The study reveals that the treatments combination of inorganic fertilizer with Ninja variety was found to be best under riverbed condition.
Highlights
Cucumber (Cucumis sativus L.) is a monoecious annual crop and belongs to Cucurbitaceous family that has been cultivated by man over 3000 years ago (Adetula and Denton, 2003; Okonmah, 2011)
The highest numbers of leaves were observed from NPK + Ninja-179 (17.93 cm) and lowest from oilseed cake + Malini (13 cm)
Days to first flowering, days to first fruit set, days to first fruit maturity fruit weight, fruit length and fruit diameter were highest from treatment combination of NPK + Ninja-179 (95.77, 101.1, 106.37,535.3 g, 21.8 cm and 6.0 cm) and lowest from treatment combination of FYM + Ninja-179 ( 66.93, 69.6, 73.53, 223.3g, 6.2 cm and 2.47) respectively
Summary
Cucumber (Cucumis sativus L.) is a monoecious annual crop and belongs to Cucurbitaceous family that has been cultivated by man over 3000 years ago (Adetula and Denton, 2003; Okonmah, 2011). The cultivated area of cucumber in Nepal was 10812 ha with production of 172566 Mt. and productivity of 15.96 Mt/ha (SINA 2018/19). Cucumber is a warm weather crop which is sown, grown and harvested over dry and rainy season (Hector et al, 2005). Cucumber bears edible fruits when ripe and much like to tomato and squash. They are often perceived, prepared and eaten as vegetables (Jacques et al, 2002; Binder et al, 1989)
