Abstract

The descriptive and vegetative characterization of fifteen ecotypes of Trichosanthes cucumerina L (snake gourd) in Nigeria was carried out. The field study was done in two locations Markurdi and Umudike to evaluate the descriptive and vegetative characters of fifteen ecotypes of T. cucumerina from Middle Belt of the country, the South-South, South Eastern part and South Western part of Nigeria. Randomized Completed Block Design was adopted for the experiment at the exploration farm of Michael Okpara University of Agriculture, Umudike and Federal University of Agriculture, Makurd at the same growing season. Descriptive and vegetative analysis was done using Minitab 16. The qualitative vegetative characteristic of snake gourd accessions vigour levels ranged from low, moderate and high. Leaf colour was from deep/pale/light green, stem colour was light, pale and deep green. The mean of the vegetative characters ranged from 2.7660-1575 ±0.48-99; cumulative variation percentage 7.65-64.75;. The germination percentage of all the accessions was significant (p<0.05). CRS – IKM (100+00), Osu – OSH – 2 (91.67±4.82).EKT – OYE was higher than Ben-MKDI (58.36±8.34). The plant height among the accessions was not significant, block was significant (P≤0.05). Leaf sizes (cm) of all the accessions were not significant (P>0.05), while main vine length (cm) at 5% probability was not significant and their treatment interaction was insignificant (P>0.05). The main vein length was highest in ABI-UKW with 636.0±164.0, followed by EKI-OYE 514.0±84.3 and least from RIV-ELE 275.7±26.4. The fruit colour at ninety days (90) of ten (10) accessions of snake guard was orange green or strip orange green and remaining accessions was milky green or light green. The fruit shape was long, thick and cylindrical. The seed colour was speckled russet.

Abstract

The study was conducted to assess biophysical and chemical properties of vertisols of Itigi District and examine their suitability for chickpea (Cicer arietinum L.) farming. Six soil composite samples were collected from top and subsoil of three selected farms used for growing chickpea and named as ITG-P1, ITG-P2 and ITG-P3. All profiles had a depth of 144 cm with heavy clay texture. pH levels varied from slight acidic to moderate alkaline, thus, favoring chickpea production. Exch. bases including Mg, K, and Na ranged from low to medium while Exch. Ca and CEC were high in all profiles, thereby, providing supportive environment for growth of chickpea. Available P was low and ranged from 0.54 to 2.10 mg/kg which was crucial for chickpea production necessitating fertilization with 30 to 80 kg of P2O5 /ha depending on the P available. The level of K varied as in ITG-P2 was adequate (>15 cmol(+)/kg) while in ITG-P1 and ITG-P3 was very low (<2 cmol(+)/kg) necessitating application of 30 kg of K2O/ha for chickpea production. Studied profiles had a slight difference in assessed characteristics, hence, the need to understand fertilizer demand for chickpea production was important.  Understanding fertility status of soils is important before investing in crop production where such information is not known.

Abstract

Erratic climatic conditions, inherent low fertility and nutrient depletion are among the most important biophysical constraints of food crops production in semi-arid African regions. This study aimed to elucidate the impact of different crop spatial arrangements associated with different levels of Phosphorus on the performance of maize-bean intercropping in Tanzania. The experiment was laid in a complete randomized design of factorial-split arrangement and three factors in different levels. Sowing patterns were randomly assigned to all experimental plots whereas Phosphorus rates were randomly assigned within a specific sowing pattern one after another. Data were subjected to statistical analysis using GenStat software of a generalized treatment structure in a randomized design. Results of the interaction between cropping pattern and the P-rates on beans and maize at a 5% level of significance indicated that grain yield, pods/plant, and biological yield did not differ significantly (P>0.05) while plant height, leaf area index, and plants per plot differed significantly (P<0.05). Intercropping affects the growth and development of component crops depending on the cropping pattern and the nutrients applied. The choice of compatible crops for an intercropping system should not exempt growth habits of the crops, land size, light, water fertilizer utilization. and other agronomic practices.

Abstract

Swiss chard (Beta vulgaris L. var. cicla), a popular leafy vegetable grown mainly for its ease of production and nutritional content, is normally used as a good source of microminerals iron (Fe) and zinc (Zn). Improving plant uptake of Fe and Zn could assist in reducing micromineral deficiencies in humans, which are a global problem. A greenhouse pot experiment was conducted at the Agricultural Research Council, Stellenbosch to assess the response in micromineral and soil trace elements uptake in Swiss chard grown under zeolite and sandy soil. The experiment consisted of four treatments, with six replicates arranged in a randomized complete block design. Zeolite was applied at 0%; 10%; 20% and 30% in combination with sandy soil. Swiss chard was harvested for micromineral analysis 143 days after transplanting. Soil samples were also collected at the end of each growing season. Swiss chard leaves were analysed for Fe, Zn, Mn, and Cu content with soil samples also analysed for the same elements. The study found that zeolite did not improve Swiss chard uptake of Fe, Zn and Mn. Soil Fe also had an inverse relationship to zeolite application while the residual effect of zeolite showed the same trend, but only in the second season. This study indicated that zeolite cannot be used to improve micromineral uptake by Swiss chard but can be used to rectify heavy metal-infested soils.

Abstract

Imbibition time and hormonal changes play a significant role in seed germination. This study, evaluated the effects of some phytohormones; indole acetic acid (IAA), abscisic acid (ABA), gibberellin and cytokinins) and imbibition time (0, 48 and 96 hours) on Tamarindus indica and Prosopis juliflora. High-Performance Liquid Chromatography (HPLC) was used to determine the concentrations of the hormones. Results indicated significantly higher and faster in P. juliflora than T. indica. The germination rate was 4.1 - 68.1% and 4.0 - 61.4%, and model for inhibition time 28.256ln(x) and 25.791ln(x), respectively. Similarly, results also expressed highly significant variable changes in the concentrations of the four studied phytohormones between T. indica (0.491 - 0.705 mg/ml) and P. Juliflora (0.109 - 1.130 mg/ml). The concentrations of IAA and ABA were significantly higher by 60.6% and 77.7% in the seeds of T. indica than P. juliflora, respectively. P. juliflora had 37.6% and 12.5% higher cytokinin and gibberellin than T. indica, respectively. Cytokinin (0.7951 - 1.0939 mg/ml), gibberellins (0.535 - 0.757 mg/ml), IAA (0.363 - 0.419 mg/ml) and ABA (0.250 - 0.335 mg/ml) also varied significantly over the periods. In general, cytokinin and gibberellins increased by 8.1 - 27.3% and 22.9 - 23.0%, while that of IAA and ABA decreased 13.6 - 15.4% and 26.4 - 34.0%, over the imbibitions time of 0-96 hours. In conclusion, higher germination of P. juliflora is attributed to cytokinin and gibberellins, and the lower germination in T. indica to the higher inhibitory effects of IAA and ABA.

Abstract

This study investigated the effect of herdsmen grazing activities on food crop production among farm youth in Nigeria. Data were collected from 120 farm youth through a structured interview schedule with a multi-stage selection process. Data analysis was done using appropriate statistics. The results reveal mean age and experience in farming of the youth were 29.03± 1.9 years and 11.11 ±7.22 years, respectively. Many (69.2%) of them were male with at least 77.5% having primary school education, and 60.88% had experienced the occurrence of Fulani herdsmen grazing activities in the past three years. In addition, 98.3 percent experienced a high effect of Fulani herdsmen grazing activities on their food crop production. Verbal warning (mean = 2.96) ranked highest among coping strategies adopted by farm youth, followed by local security (mean = 1.94) among others. At p<0.01, the perception of the grazing activities (r = 0.595), experience in farming (r = 0.411), and coping strategies (r = 0.446) had a substantial association with the effect of the Fulani herdsmen grazing activities on food crop production. The study then concluded that the Fulani herdsmen grazing activities had a high effect on the food crop production of the farm youth.

Abstract

A conventional linear programming model (LPM) for feed formulation of lactating cattle will overlook the variation in feed components. LPM only considers the mean composition of feed values, regardless of variations, the confidence in satisfying the nutrient need falls to 50%. Whereas the stochastic model (SM), which takes into account both the mean and variation of feed composition and provides 90-99% confidence in meeting the nutrient need. In present work, we have proposed SM for least-cost feed formulation of lactating cattle where the variation in the composition of nutrients like crude protein (CP), Calcium (Ca) and Phosphorus (P) in the feedstuff are considered. Data provided by the National Research Council (2001) are the basis for the current analysis. These SMs are resolved using M.S. Excel's Generalized Reduced Gradient (GRG) nonlinear and LINGO's Nonlinear solver, and the results are compared to LPM; the feed formulated by SM (90 % and 99 %) has the lowest cost when compared to LPM. Nutrients estimated by LPM, SM by GRG nonlinear, and SM by Nonlinear solver utilized for feed formulation had no significant differences as (p>0.05).  When compared to LPM, the stochastic model is a better technique, particularly when dealing with nutrient variation.

Abstract

Patchouli has begun to be widely cultivated by farmers in Burana Village with its easy cultivation and offer a promising profit. This study aims to determine whether or not it is feasible to develop a patchouli farming business  in  this area. Quantitative research is used to anlyze farm costs, farming profits, farm income, return cost ratio (R/C), capital productivity (n/C) and break-even point analysis (BEP). The results showed that the average area of farmers' land is 47.22 acres, so the average cost of production on patchouli farming is Rp. 23,521,073, and the average revenue obtained is Rp. 30,486,379, then the average profit for each respondent is Rp. 6,965,306, so the R/C ratio obtained is 1.3 because the value of the R/C ratio is greater than 1, so patchouli farming is feasible. The value of π/C 0.29 indicates a profitable business where each additional cost of Rp. 100 then a profit of Rp. 29 (29%). The analysis of break-even point for the production volume in patchouli farming is 53,458 kg, meaning that at 53,458 kg the patchouli business is profitable because the patchouli product number of 53,456 kg is below the average product figure of 69.998 kg. Analysis of the point of return for the cost of production in patchouli farming is Rp. 336,025 shows that it is still below the market price of Rp. 439,995, means that the patchouli business is profitable.
