ABSTRACT:

Two locational trials were conducted during 2021/2022 dry season at Makera irrigation farm Dutsin-Ma Local Government Area and in Ajiwa, Batagarawa Local Government Area of Katsina State. The study was aimed at determining the correlation between growth and yield of cucumber (Cucumis sativus L.) to time and rate of NPK (20:10:10) fertilizer application in the Sudan savanna. The treatments consisted of factorial combinations of five NPK application times (at Planting (P); 3 WAP; P+3WAP; P+6WAPand 3WAP+6WAP) and five rates of NPK (20:10:10) fertilizer (0, 30, 60, -1 90 and 120 kg NPK ha ). These were laid out in randomized complete block design (RCBD) and replicated three times. The results showed that time of application of NPK (20:10:10) significantly increased the growth and yield parameters of cucumber measured on number of leaves, vine length 2 (cm), stem diameter (mm), leaf area (cm ), number of fruit per plant and per hectare, fruit diameter (mm), fruit length (cm), fruit weight per plant (g), fruit weight per plot (kg), and fruit yield per -1 hectare (kg ha ). The correlation analysis of the above measure parameters are showed in table 2 and 3. Based on research findings of the experiments it can be concluded that for optimum cucumber yield; fruit yield parameters should be positively correlated with growth parameters. Therefore, it can be recommended that for good cucumber production yield and growth parameters has to be positively correlated with each other so that farmers within the study area can maximize benefits of cucumber production.
