Comparative Effect of Sesasons, Organomineral Fertilizer Ratios and Profitability of Cucumber Production (Cucumis Sativus L.) in Southwest Nigeria
Ensuring an adequate good nutritional supply has been a major concern of mankind over the millennia, and even in today’s modern world of great scientific and technological achievements. Fruits and vegetables are of great nutritional value and they are sources of vitamins and minerals, thus, essential components of human diet. Premise to the above challenge there is the need to evaluate the economics production of cucumber under different agronomic management in order to encourage local production among small holder farmers. Experiment to document the productivity of cucumber was in early and late cropping seasons of 2016 at Teaching and Research Farm of Obafemi Awolowo University (OAU), Ile-Ife, Nigeria. The experimental design was a split-plot laid out in a Randomized complete block design (RCBD) with three replications. The main plot include; four vine trailing methods (Staked, Trellised, Mulch and control) while sub-plots were six levels of organomineral fertilizers fortified in ratios (1:3, 1:1, 3:1 of organic with inorganic fertilizer;, 100% NPKha-1, 100% Organic Nha-1 and 0% Nha-1 as a control). The fertilizers were aimed to give 100% kg Nha-1. Data were collected on fruit yield per plot and yield was converted to hectare. The data collected were subjected to analysis of variance (ANOVA) using (SAS, 2003). Means of significant treatments were separated using the Duncan`s Multiple Range Test (DMRT). Also, gross margin analysis was carried out to know the profitability of the production seasons of cucumber. The data obtained from the experiments show that type of vine management and fertilizers significantly affected the yield of cucumber. Among the vine trailing methods investigated mulched method significantly enhanced the yield and subsequently produced the higher number of fruits and resulted in higher fruit yield per hectare. Ratio 1:1 combination of inorganic and organic fertilizers resulted in the highest number of cucumber fruits and…
The effect of different animal protein sources in broiler production was investigated. 300 seven-day old broilers of equal average initial weight were randomly allotted into five treatment groups with 3 replications of 20 birds each and at the end of 28 days, birds were weighed again and re-randomized to the five treatment groups with 3 replicates of 16 birds each. The diets consisted of four animal proteins. Treatment 1(Control) had 4% fish meal, while diet 2, 3, 4 and 5 had 1% of each of the animal protein source, 4% crayfish waste meal, 4% blood meal and 4% meat meal respectively. The study was conducted for 56 days of 28days starter phase and 28days finisher phase. The results showed blood meal to have the highest (P0.05) depression. The least cost per kg feed and least cost per kg weight gain (N) were observed with birds on crayfish diets. There was better (P
A study aimed at replacing whole maize with maize sievate/palm oil in broiler diets was carried out to evaluate their economic and biological growth performance. Maize Sievate: Palm Oil mixture (40:1) was used to replace whole maize both in the starter and finisher diets at 0, 25, 50, 75 and 100% whole maize replacement levels. The experiment was laid out in a completely randomized design with five treatments; three replicates each comprising of 20 day – old broiler birds at the starter phase. These birds were re-randomized at the finisher phase, with each treatment having 54 birds (18 birds/replicate). The starter and finisher phases lasted 28 days each. The average daily feed intake in both phases were not significantly (P
Effect of Configurations on the Coefficient of Uniformity and Water Distribution Using Single-Nozzle Plastic Sprinkler Heads
This study was conducted during February and March 2014 in the Demonstration Farm of the Faculty of Agriculture, University of Khartoum at Shambat (longitude 32o32’E, latitude 15o40’N and altitude 380 m amsl), on a total area of 40 m x30 m .The objective of the study was to determine the effect of layout configuration under different operating pressures (1.0, 1.5 and 2.0 bar) on the coefficient of uniformity (CU %) and distribution uniformity (DU %). The tested configurations were the square, rectangular and triangular sprinkler patterns by using single- nozzle plastic sprinkler heads (LEGO).For each configuration, a solid-set sprinkler system was designed and installed .Catch cans were placed at centre of grids of 4×4 m. The completely randomized design was used, and treatments were replicated three times. For each treatment the system was run for one hour. The data was analyzed, using Minitab Software Version 16. The triangular configuration recorded the highest uniformity coefficient and uniformity of distribution under 2 bars operating pressure. The mean CU% of value (87%) and DU% of value (80%) at (P≥ 0.05) gave the following descending order: triangular > square > rectangular configuration. All values obtained were within the acceptable range of standards set by Keller and Bliesner 1990. The appropriate operating pressure and sprinkler configuration should be considered when designing and installing a solid-set sprinkler system.
The ability of organic nitrogen fixation (BNF) to supply all the nutrient N in soybeans, considering high productivity, is questioned about the possible need to complement of this nutrient to the culture through other means of supplemental conventional fertilization. In this work the aim was to check the response of soybeans inoculated with bacteria of the genus Rhizobium and Bradyrhizobium, conditioned to supplementary nitrogen fertilization in the reproductive phase, in soil and in leaf. The treatments were the witness (without application of N), 30 and 60 kg of N ha-1, via soil and 2% solution of N, R1 and R 5.3 phases, in a randomized block design with 4 replications, using the soybean cv. Desafio, with the seeds inoculated with bacteria of the species Bradyrhizobium japonicum and Bradyrhizobium elkanii (strains Semia 587 and Semia 5019). The late application of N into R1 and R 5.3 provided increase in grain productivity of 478.6 kg ha-1 and 472.8 kg ha-1, respectively. The application, via soil, N in R1 features better harvest index, when compared to R 5.3. The late application of 2% solution of N, via foliar, provided no increase in productivity of soybean culture.
The inception of legalization of Cannabis in America has paved way for the extensive research on this medicinal and religious plant all over the world. Despite the long relationship of Nepalese community with Cannabis since time immemorial, where it used to be used for both medical as well as recreational purposes, its illegalization during 1970s led to significant drop in one of the major source of income for numerous household and their families thereby impacting GDP of the country. Due to the geographical diversity of Nepal with most parts covered by hills and mountains along with the fertile land of plain region, the country has been a home to many landraces of Cannabis and we believe that it has the potential to be one of the major hub of harvest of Cannabis and Cannabis derived pharmaceutical industry. In this review, we have focused on the native strains of Cannabis in Nepal which are sold in the markets all over the world legally and how the legalization of Cannabis would bring remarkable upgrade to the country reeling under low economy and would be a great boost for the country to rise above its status of developing country. Apart from this, we have also proposed the steps that have to be taken at the government level for the stepwise legalization, substantial growth of the native strains and be a major leader in the world market by the export of Cannabis and its derived products.
Farmer involvement in the development of cowpea varieties for cultivation is an integral component for crop improvement in Northern Ghana where the bulk of cowpea is produced. The objective of this study was to assess farmers’ perception about the effect of drought on cowpea production, identify production constraints and determine farmer preferred traits using Participatory Rural Appraisal. Five cowpea producing districts were selected across the three Northern regions. Fifty cowpea producers, consumers and traders were randomly selected for the study. Data was collected using questionnaires and focus group discussions. Data was analysed using SPSS version 22. Kendall’s Coefficient of Concordance statistical procedure was used to identify and rank farmers’s constraints and preferences, and to measure the degree of agreement among the respondents. Ninety three percent of the farmers reported that, the number of hot days has increased over the past ten years. Farmers across all the three regions linked the effect of drought to the stages of cowpea growth with podding stage seen as the worst affected. About 70% of the farmers preferred varieties with large grain size, smooth or rough textured seeds with white coats. About 84 % of farmers preferred varieties that were early and drought tolerant.
Cultivated areas of soybean in Brazil have been increasing with each harvest and the seed market is moving in the same direction, launching new varieties every year. To increase not only planted area but also productivity, it is necessary to use technologies and use integration systems. In this study, the effect of pollination by honeybees on two soybean varieties in two consecutive years was evaluated. Three treatments were established: cages with Apis mellifera honeybees, cages without bees and free areas for insect visitation. The results showed an increase 6.45% of soybean yield in areas with free access to insect visitation. While in the cages with the introduction of Africanized honeybee colonies the increase was 13.64%. These results indicate that even in the most recent cultivars, cross pollination can show productivity gains even in an autogamous species.
Effect of Feeding Traditional Summer and Winter Rations on Minerals Contents in Milk of Cows and Buffaloes
Twenty lactating Friesian cows and 20 lactating buffaloes with an average live body weight of 500 kg at 2-5 lactation seasonsafter the peak of lactation (60 days from parturition). Animals were fed summer rationconsisted of 40% concentrate feed mixture (CFM) + 40% corn silage (CS) + 20% rice straw (RS) (10 cows and 10 buffaloes) and winter ration consisted of 40% CFM + 40% fresh berseem (FB) + 20% RS (on DM basis) (10 cows and 10 buffaloes).Milk samples were taken from each cow and buffalo three times biweekly and prepared for minerals determination. The contents of Ca, K, Zn, Mn and Fe were higher in fresh berseem, while the contents of P, Mg, Na and Cu were higher in concentrate feed mixture, however, the lower contents of all minerals were detected in corn silage and rice straw. The contents and intake of all minerals were higher in winter ration containing fresh berseem than summer ration containing corn silage. The excretion of all minerals in feces and urine as well as absorption and retention increased significantly (P
Improved Dual Purpose Sorghum (IDPS) (Sorghum bicolor -Var Ikinyaruka) was harvested at six physiological growth stages and ensiled to evaluate the effect of growth stage on silage quality. The 6 treatments based on physiological growth stage of the sorghum were: bloom stage (PS1), soft dough stage (PS2), hard dough stage (PS3), physiological maturity stage (stalks with grains), (PS4), physiological maturity stage (stalks without grains) (PS5), and 1 month post grain harvest (PS6). The material was ensiled for 30 days in mini-silos made from 1000g plastic bags. The parameters monitored were silage Dry Matter (DM), Crude Protein (CP), Neutral Detergent fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL), In-vitro Dry Matter Digestibility (IVDMD), pH and ammonia–N. The highest silage DM (30.60) was achieved at PS4 compared with 22.00, 26.00, 29.60, 29.50 and 27.10 for PS1, PS2, PS3, PS5 and PS6, respectively. The CP content decreased with maturity from 7.72 at PS1 to 7.01, 7.00, 7.00, 6.71 to 6.68 at PS2, PS3, PS4, PS5 and PS6 respectively. NDF and ADF at PS1, PS2, PS3, PS4, PS5 and PS6 were 56.50, 62.80, 65.97, 66.24, 67.27, 70.76 and 29.46, 36.49, 41.82, 41.95, 42.76 and 46.37 respectively. ADL was 3.54, 5.50, 7.35, 7.47, 7.52, and 8.50 for PS1, PS2, PS3, PS4, PS5 and PS6 respectively. Highest silage IVDMD of 56.06 was at PS1 secernated with 53.70, 52.47, 52.32, 52.21 and 42.52 achieved at PS2, PS3, PS4, PS5 and PS6 respectively. Silage from hard dough stage (PS3) yielded silage with highest nutritive value.
