To evaluate the effect of four agricultural practices on grain yield, two varieties (IT-16 and IT-18) of cowpeas were tested in the agricultural year 2016/2017 an experimental field where the following agricultural practices were tested: tillage, tillage + mulch, zero tillage and zero tillage + mulch. The randomized complete blocks design, a scheme consisting of two factors: agronomic practices and varieties was used. The plant height, number of pods per plant, weight of 100 seeds and grain yield in kg ha-1 were considered as parameters for analysis. From the results, it was concluded that for the yield of grain of different varieties under study, the variety IT-18 subjected to zero tillage + mulch and the variety IT-16 subjected to tillage had better performance achieving 2600.00 kg ha-1 and 1725.00 kg ha-1 respectively; therefore, recommended to the farmers.

“…The rainfall pattern is bimodal, with two-rainfall seasons, 'belg' (February/March -April) and 'Meher' (July-September) with a mean annual rainfall of 950mm. The mean daily temperature range is of 16-21 °C [11]. The soil type of the experimental fields is clay loam, with a pH of 6.98.…”

The present study was conducted to assess seed rate (SR) and nitrogen rate (NR) effects on biomass yield and nutritional quality of oat (Avena sativa L.) at Sirinka, North Eastern Amhara, Ethiopia on July 2018. Levels of SR were 60, 80 and 100 kg/h and that of NL were 50, 100 and 150 kg/ha in the form of Urea (46% N). The experiment was conducted in a 3x3 factorial arrangement of treatments in a Randomized Complete Block Design (RCBD) with 3 replications giving a total of 27 plots, each measuring 2×1.4 m2. Growth and yield parameters were analyzed. Results showed that the interaction between seed rate and nitrogen rate had a significant (p<0.05) effect on almost all parameters measured except tiller number per plant (TNP). Green forage yield and dry matter yield increased with increasing level of seed rate and level of nitrogen. Generally, combination of 100 kg/ ha seed rate and 150 kg/ha nitrogen recorded higher forage yield. Thus, seed rate of 100 kg/ha and nitrogen fertilizer rate of 150 kg/ha Urea can be recommended for use by farmers in Sirinka area and other areas having similar agro-ecologies and soil type.

This study sought to identify the most effective weed control methods for enhancing growth, yield and grain quality in cowpea and to reduce weed interference during the major and minor rainy seasons of 2022 at Juaso in the Asante Akim South Municipality, Ghana. Sun‐zema at 30 mL/15 L of water, Supremo (90 mL/15 L of water), Vezir (90 mL/15 L of water), Ogyama (100 mL/15 L of water) and Benfop (100 mL/15 L of water), hoeing, cutlass weeding and no weeding were evaluated in a randomized complete block design with three replicates. Data on weed flora, plant height, number of leaves per plant, days to 50% flowering and pod formation, grain yield and yield components and proximate composition of cowpea grains were collected and subjected to analysis of variance using GenStat statistical package (11th edition). Differences in means were compared using the Fisher's protected least significant difference at a probability level of 5%. Significant (p < 0.05) improvements in the growth of cowpea due to hoe weeding were observed. Hoeing, Vezir and Supremo herbicides increased grain yield during the major rainy season, with hoeing recording the highest value (0.53 ± 0.07 ton/ha), whereas Supremo herbicide recorded the highest grain yield (0.38 ± 0.06 ton/ha) during the minor season. Hoeing recorded the least grain moisture contents of 7.45 ± 0.62% and 6.35 ± 0.62% in the major and minor seasons, respectively, which could enhance postharvest handling. Application of Supremo, Sun‐zema and Ogyama reduced weed diversity in the study area. The study recommends hoeing during the major season and herbicide application (Supremo) during the minor season.
