“…Sanchez et al (1997) have reported an estimated depletion rate of 660 kg N/ha, 75kg P/ha and 450kg k/ha from about 200 million hectares of cultivated lands of 37 African countries in the past 30 years nutrient. Under continuous cropping system inherently infertile soils require external input of fertilizers and materials for maintaining fertility and productivity (Nyathi and Campbell, 1995). Land degradation manifested in the form of soil fertility depletion is considered as the root cause of declining fertility under small holdings (Stoorvogel and Smaling, 1990;Smaling et al, 1997) and nutrient imbalance on large scale farms (Nandwa and Bekunda, 1998).…”

Response of P2O5, K2O and seed rate on grain yield of Pearl millet variety 'Bajra 2002' was studied in field experiment during kharif seasons of 2015 and 2016. Fifteen management practices such as three P2O5 and K2O levels and five seed rates were imposed with three replication using split plot design. Parameters included plant height, stem diameter, tiller/m 2 , head/m 2 , head/plant, 1000 grain weight, number of grains/head and seed yield kg/ha. Fertilizer and seed rate treatments had significant effect on plant height, stem diameter head/m 2 and grain yield/ha. P2O5 and K2O showed no significant effect on head/plant, tiller/m 2 1000 grain weight and number of grain/head. The highest grain yield production (4211.8kg/ha) was recorded in the combination of 3.75kg/ha seed rate and fertilizer dose of 57-60-60 NPK kg/ha. The highest grain yield from pearl millet crop was obtained by the fertilizer dose of 57kg N + 60kg P2O5/ha while statistically similar but economical grain yield was obtained with the fertilizer dose 57kg N + 40kg P2O5 /ha.

“…However, organic manure is usually required in large quantity to sustain crop production and likely may not be available in small proportion for the small-scale farmers (Nyathi and Campbell, 1995). Besides that, organic manure is a slow releasing nutrient.…”

This study was designed to observe the effects of different application rates of inorganic fertilizers on growth, yield and quality of okra (Abelmoschus esculentus L. Moench) under BRIS soil condition. The field experiment was conducted during July, 2014 to April, 2015 at the teaching and research farm of University Sultan Zainal Abidin (UniSZA), Besut Campus, Terengganu. Performance of okra variety Singa 979 was assessed by application of NPK at different rates (0 kg ha -1 (control), 150 kg ha, 170 kg ha . The treatments were fitted in a randomized complete block design (RCBD) replicated thrice. Data collected for growth and yields performances included plant height, number of leaf/plant, leaf area, number of branch/plant, chlorophyll content, photosynthesis rate, transpiration rate, internal CO 2 , stomatal conductance, number of flower/plant, number of pod/plant, weight of pod, number of seed/pod and total soluble solid (TSS) of the pods. Based on the results obtained from this experiment, application of NPK at the rates of 190 kg ha -1 and 210 kg ha -1 shows the highest growth and yield performance. It is followed by application of 170 kg ha -1 and 150 kg NPK/ha -1 in decreasing manner. No application of NPK shows the lowest growth and yield response. The significance of this research was to study the minimum rate of NPK on the effect on okra ground around the sea shore of Terengganu or in BRIS soil

“…Slightly better results were obtained in consequence of treatment with B. spiciformis litterfall mixed with fertilizer as well as treatment with sole fertilizer; however, when compared to the control, the results were not considerably different. Hence, there was found no positive effect of litterfall on the site productivity in the case of maize crops (Nyathi and Campbell 1995).…”

“…An attempt to enrich the nursery substrate with litterfall does not always bring results as expected. This was demonstrated by Nyathi and Campbell (1995) in the study on the effects of litterfall of Zimbabwe native tree species Brachystegia spiciformis Benth. (miombo tree) and Leucaena leucocephala lam.…”

In this article we analysed the influence of plant-based organic admixtures on the germination process of seeds and the early development of Scots pine Pinus sylvestris L. seedlings. The intensity of dumpin-off diseases within the culture was recorded after applying each of the admixtures. Organic material of nettle Urtica dioica L., softwood litter, hardwood litter and peat were applied to the nursery substrate in two ways, either as an admixture in crushed form or in granulated form. None of the introduced admixtures influenced the germination of seeds or the survival rate of pine seedlings positively. The best results were obtained with a substrate without admixtures used as a control, which is the most common nursery substrate. The worst seed germination rate was observed on the substrate enriched with the organic material from nettles. In pots with granulated organic material from hardwood litter, significantly more seedlings showed signs of post-emergence dermatitis. In all other cases, there was no clear difference between the crushed or granulated admixture in either germination or survival of seedlings. We furthermore demonstrated that the process of granulating plant material leads to an approximately 10-fold increase in the bulk density of the granulated substance, which translates directly into volume reduction.
