SUMMARYA field experiment was made with pigeon pea (Cajanus cajan (L.) Millsp.) at the Indian Agricultural Research Institute, New Delhi, during the rainy seasons of 1975 and 1976 to study the effects of plant type, plant population density and the application of phosphate fertilizer on growth and yield of pigeon pea. Cultivars BS-1 and UPAS-120 produced significantly more grain with 100 × 103 plants/ha, whereas the cultivar Prabhat produced most when 200 × 103 plants/ha were grown. Application of 13 kg P/ha increased most growth and yield attributes and increased the grain yield significantly over the control to which no P was given; however, no additional increase was obtained when 26 kg P/ha was given. The highest-yielding cultivar BS-1 benefited most from phosphate fertilizer.

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.

SUMMARYGrowth, yield and incidence of lodging of poppies were studied in Tasmania at 10–200 plants/m2 and at nominal rectangularities (within-row: between-row spacing) ranging from 1:1 to 10:1. In 1983/84 and 1988/89, there were asymptotic relationships between plant population density and both total dry-matter production and total head (capsule plus seed) yield at maturity. In 1983/84, a season with above-average wind, the incidence of lodging increased as density increased to > 50 plants/m2; morphine concentration decreased as density increased to > 100 plants/m2. This resulted in parabolic relationships between yield of erect (machine-harvestable) heads and yield of morphine from erect heads with plant density, the maximum morphine yield from erect heads being achieved at 70 plants/m2. In 1988/89, a season with below-average wind, the effects of lodging were less severe at high densities and the components of ‘erect’ yield were adequately fitted by an asymptotic function. Rectangularity of 1:1 gave higher total dry matter production, total head yield, yield of erect heads and morphine yield from erect heads than 4:1 and 10:1. Since calm conditions similar to those of 1988/89 occur only once in every 4 years, growers should be encouraged to establish c. 70 plants/m2. As most commercial crops in Tasmania are drilled in 150–175 mm rows, growing at 70 plants/m2 to maximize the effect of plant density would also approximate to the ideal rectangularity (2:1 in this case).

Growth and yield of chickpea, Cicer arietinum cv. Tyson, were studied at 4 row spacings (180, 360, 530 and 710 mm) and 4 plant population densities (14, 28, 42 and 56 plants m-2) in factorial combination in a wet and a dry growing season on a vertisol at Dalby, south-eastern Queensland. In both years, row spacing had only a small effect on above-ground dry matter production and yield, and there were no significant interactions between row spacing and plant population density. Above-ground dry matter production increased significantly with increase in plant population density for about 120 days after sowing. Seed yield increased significantly from 104 to 126 g m-2 in the drier season (106 mm rain, May-October) with increase in plant population density from 14 to 56 plants m-2. In the wetter season (286 mm rain, May- October), the corresponding trend in yield was from 262 to 287 g m-2. The response was attributed chiefly to larger seed size in the wet year, and higher harvest index in the dry year. We conclude that a density of at least 40 plants m-2 is required to attain maximum seed yield in southeastern Queensland. Although row spacing had no significant effect on yield, our earlier research indicated potential benefits from narrow row spacing, particularly for mechanised crop production.

Abstract Soils of the savannah zones of Nigeria are low in plant nutrients and peasant farmers; therefore, rely on external inputs in the form of organic and inorganic manure for sustainable yield. They also sow their seeds at suboptimal plant population density, thereby providing opportunity for weeds to thrive. Moreover, farmers use saved seeds from the previous cropping season for planting, which often results in low yield. A study was conducted to assess the growth and yield of two maize cultivars under the influence of organic fertilizer and plant population density. Treatments used were factorial combinations of three levels of poultry manure (0, 2.5, 5.0 t/ha), two population densities (95,556 and 53,333 plants/ha) and two maize varieties (DMR-ESR-Y and Suwan-1-SR). Data were collected on number of leaves, plant height, leaf area, stem girth, root and shoot dry weight, total dry weight, days to tasseling, days to silk appearance, grain yield per hectare, number of seeds per cob, seed rows per cob, weight of 100 seeds and shelling percentage. The results revealed significant improvement (p≤ 0.05) in all parameters examined, when 5 t/ha poultry manure was applied to Suwan-1-SR at density 53,333 plants/ha. However, there was marginal difference between 5 and 2.5 t/ha in grain production. Therefore, application of 2.5 t/ha poultry manure for production of Suwan-1-SR maize variety at plant density 53,333 plants/ha could be used for getting optimum yield, that can feed the growing population of maize consumers coupled with better straw production for animal feed.
