“…The tuber yield was lower per plots where the plants were spaced 120 cm × 30 cm compared with those where the plants were spaced 60 cm × 30 cm, 60 cm × 45 cm, and 90 cm × 30 cm. Similar finding were observed by Adubasim et al, (2017).…”

“…In cover crops, highest leaf yield has been reported by Obalum et al (2017) in fluted pumpkin planted at closer spacing of 25 cm × 25 cm. Also, Adubasim et al (2017) obtained highest tuber yield in sweet potato planted at close spacing of 30 cm x 60 cm. Essentially, plant density plays a crucial role and contributes to the yield and marketable yield properties which in turn translate to economic returns.…”

This study assessed the influence of three plant populations (18518, 27777 and 40000 plants ha -1 ) on fruit and seed yield characters in 16 genotypes of Capsicum frutescens in 2010 and 2011 cropping years using a 3 x 16 split plot arrangement fitted into a randomized complete block design. Plant population and genotype formed main and sub-plots, respectively. Data collected on fruit and seed yield characters were subjected to analysis of variance after which means were separated using Fisher's Least Significant Difference. Correlation analysis was also carried out among the characters. Significant and highest (P < 0.01) number of fruits per plant, single fruit weight, fruit weight per plant, number of seeds per fruit, 100 seed weight, seed weight per plant and seed weight per fruit were obtained under 18518 plants ha -1 while highest (P < 0.05) fruit yield ha -1 (11.3 tons) and seed yield ha -1 (698.7 kg) were obtained under 40000 plants ha -1 . Top fruit and seed yielding genotypes across the three plant population were PP9955-15 and Chilli 14, respectively. Number of fruits per plant showed negative and highly significant correlation with single fruit weight, fruit length, fruit width, number of seeds per fruit, 100-seed weight and seed weight per fruit. Significant positive or negative correlations were also observed among other characters. Plant population of 40,000 ha -1 using 50 x 50 cm spacing is recommended for high fruit and seed yield in C. frutescens production.

“…Kafiriti and Deckers (2001) also reported maximum yield of sesame with close spacing of the crops. Adubasim et al (2017) achieved highest tuber yield of sweet potato with closest plant spacing of 30 cm by 60 cm. Similarly, Obalum et al (2017) recorded higher leaf yield of fluted pumpkin with narrow than with wide spacing.…”

Sesame (Sesamum indicum L.) is an important oil-seed crop cultivated for its high nutrition and edible seeds. However, its cultivation is affected by low soil fertility, wrong choice of plant population density and time of sowing. The experiment was carried out during the 2016 and 2017 cropping seasons at the Research Site of Agronomy Section, Kabba College of Agriculture, Kabba, Kogi State, Nigeria. The experiment evaluated the influence of plant population density and organo-mineral fertilizer rates on the performance of Sesame in Kabba, Kogi State, Nigeria. The experiment was a split plot design replicated thrice. The main plot treatment was three plant population density (P1 = 111,111; P2 = 83,333 and P3 = 66,667 plants ha–1) and the sub-plot treatment was four organo-mineral fertilizer rates (F0 = 0, F1 = 500, F2 = 1000, F3 = 1500 kg ha-1). Data were collected on growth, morphological characters (plant height, number of leaves, number of branches) and yield components (number of capsules plant–1, 1000 seed weight and yield ha–1). The result showed that the plant at P1 produced the tallest plants throughout the period of sampling, which was closely followed by P2 while P3 produced the shortest plants. Numbers of capsules plant–1 was highest in plots with P1 which was statistically the same with the number of capsules plant–1 in P2. Number of capsules plant–1 in P1 and P2 were statistically better than the plots with P3. Plots treated with rate F2 gave the highest number of capsules and also recorded the highest yield in 2016 and 2017 growth seasons. The results indicated that Sesame with closest spacing was better in terms of seed yield land–1 area while widest spacing gave the highest individual yield attributes. For economic use of land, it is concluded that plant population density at 111,111 be adopted in the production of Sesame. Best growth and yield performance of Sesame was achieved with 1500 kg ha-1 of organo-mineral fertilizer and is recommended for optimum production of Sesame in the study area.

Sweet potato (<i>Ipomoea batatas</i>) growth and tuber yield as influenced by plant spacing on sandy loam in humid tropical environment

Abstract: The choice of appropriate plant spacing that gives optimum density of sweet potato (Ipomoea batatas (L.) Lam) is crucial for its productivity, considering that plant density of cover crops affects above-ground access to sunlight, degree of soil surface cover, and below-ground tuberization.
