The Response of Date Palm Phoenix dactylifera L. cv. 'Barhii' to Spray by Two Vital Stimulators Terrasorbe and Kelpak

A comprehensive survey was conducted at different provinces of Saudi Arabia (SA) to investigate predacious prostigmatid mites (Acari: Trombidiformes: Prostigmata) mainly collected from the date palm, Phoenix dactylifera L. (Arecaceae) agro-ecosystem. A total of 41 species belonging to 28 genera in 14 families are recorded in the present study. Out of these, three families, 18 genera and 36 species are new to the mite fauna of SA. The new species, Neobonzia tabukensis sp.nov. (Cunaxidae), Cheletomimus (Philippicheyla) taifensis sp.nov. (Cheyletidae) are described and illustrated. A checklist of predatory prostigmatid mites from SA is given. A key to all terrestrial predatory prostigmatid mites, excluding Parasitegona and Heterostigmatina, reported from SA is provided. Also, a key to world species of the subgenus Philippicheyla Corpuz-Raros of the genus Cheletomimus Oudemans is given.

ABSTRACT Studies on the effect of transplanting methods and NP – fertilizer rates on leaf length of a female date palm offshoot have been conducted over a period of 25 months (September, 2017 – September 2019). The trial was sited at the Date Palm Research Sub – station/ Federal University Dutse (11o50’N, 09o25’E) in the Sudan Savanna ecological zone of Nigeria. The treatments consisted of two transplanting methods (Direct: detachment of offshoot from the parent palm and directly transplanting into the field, and Indirect: detachment of offshoot from the parent palm and keeping in the nursery for 3 months before transplanting into the field) and five NP fertilizer rates Control (0g N + 0g P), 80g N + 40g P, 160g N + 80g P, 240g N +120g P and 320g N + 160g P) arranged in a randomized complete block design with three replications. Indirect transplanting of date palm through nursery proved more effective than direct transplanting as it produces statistically longer leaves which are an indication of better chances of crop survival, establishment and yield. Rate 320g N +160g P statistically outperformed other rates in the production of longer leaves throughout the sampling periods. Interaction between transplanting methods and fertilizer rates was highly significant in most of the sampled periods except in June and September, 2019. A combination of indirect transplanting method with rate 320g N +160g P that produced longer leaves is recommended for adoption in the Sudan Savannah ecological zone of Nigeria.
