A planting distance experiment with the Sunrise Solo papaya cultivar was performed in St. Augustine, Trinidad. West Indies, in which the distance between plants was varied from 0.602 to 3.046 m. Each plant received a total of 340.2 g of 13-13-20 fertilizer in six bimonthly applications. Plant height, stem diameter, and fruit yields during a 5-month harvesting period attained maximum values of 309 cm. 30 cm. and 328.86 ql4/ha, respectively, at planting distances of 0.715, 2.206, and 0.987 m. Petiole length did not vary significantly with variation in planting distance. Fruit yield during the 5-month harvest period (August to December 1969) increased from 58.38 ql/ha with a planting distance of 0.602 m and 93.89 ql/ha of 13-13-20 application to 328.86 ql/ha with a planting distance of 0.987 m and 34.87 ql/ha fertilization, decreasing to about 70 ql/ha as planting distance increased to 3.046 m and fertilization rate decreased to 3.66 ql/ha. A quartic algebraic equation fitted to the data explained 51% of the variation of fruit yield as a dependent variable on planting distance.

Four Levels

The experiment was carried on a Coto clay (an Oxisol). The effect of four levels of N (0, 57, 170 and 340 kg/ha) and four levels of B (0, 2.3, 4.5, 6.8 kg/ha) were determined using the P.R. 7-65 papaya variety. Treatments were initiated when the transplanted seedlings were three months old, and were repeated every six weeks. The information recorded showed the following results: Increments of N and B levels did not show a marked effect on plant height and stem diameter. Boron tended to be more effective than N in increasing stem height and diameter. The petiole fresh and dry weights increased linearly as the N and B levels were raised. The number and weight of fruits borne on female and hermaphroditic trees increased linearly as the N and 8 levels were raised. The results of the experiment showed that the papaya plant requires a high N and B fertilization rate.

`Raritan' and `Guardian' strawberry were grown in the matted row system with controlled plant densities of 1, 2, 3, 4 or 5 plants/0.09m2 for comparison to a non-thinned matted row averaging 9 plants/0.09m2. Nitrogen treatments were superimposed on plant spacings at 3 week intervals in preharvest and postharvest applications. Total seasonal available N was 0, 36, 54 and 76 kg/ha. Fruit yield per plant decreased as plant population increased. Berry size declined with increased plant population but number of fruit per plant was not influenced. For both cultivars, plant populations of 4 to 5 plants/0.09m2 resulted in maximum fruit yield. Number of branch crowns for all treatments was 2.5-3.5/plant in the second growing season. Branch crown numbers were reduced with higher plant populations. N effects were independent of plant population effects and did not compensate for lower yields at low plant populations in more or larger berries. Optimum water management may be more important than N fertilizer in determing strawberry plant growth and yield.

Micronutrients, particularly Zinc (Zn), play a vital role in the growth and development of plants due to its catalytic effect on many metabolic processes. However, the varietal responses to growth and yield vary significantly. A screening experiment was conducted to know the growth and yield response of six capsicum hybrids viz., Indra, Priyanka, Inspiration, Massilia, Bachata and Local green with two levels of ZnSO4 (with and without  ZnSO4) as basal soil application. The growth and yield attributes at harvest stage was recorded. The dry matter production (DMP) and fresh fruit yield was also noted for all the six hybrids. Results revealed that, Zn fertilisation significantly improved the plant height, root growth, fruit development as well as fresh fruits yield. Higher plant height (83 cm), root length (37 cm), root volume (13 cc), fruit numbers, fruit weight (15 and 133g), fruit length, girth, pericarp thickness (9.17, 8.25 and 0.67 cm), DMP (65.0 g pot-1) as well as fresh fruit yield (4.70 kg pot-1) were observed with Indra followed by Inspiration and Bachata. Lesser response for the Zn application was noticed with the local green hybrid for various growth and yield traits. Indra was found to be highly responsive to Zn fertilisation while Inspiration, Bachata, Massilia, and Priyanka were medium responsive and local green hybrid was observed to be less responsive to Zn fertilisation.

Abstract A field experiment was conducted on sorghum (Sorghum bicolor (L.) Moench cv.) under three cutting system to determine the effect of nitrogen on growth and yield at University of Agriculture Faisalabad, Pakistan, during the season 2010-2011. The experiment was laid out in Randomized Complete Block Design (RCBD), using three replications. There were four levels of nitrogen 0, 50, 75 and 100 kg N/acre in the form of urea. The growth parameters like plant height, number of leaves, leaf area is determined periodically. First reading taken after 20 days of sowing while second and third was taken after 15 days of first cutting. Yield parameter like plant population, fresh and dry weight was determined in three cuttings. Results showed that increasing nitrogen dose increased all growth attributes. Results revealed for first, second and third cuttings showed significant differences at all growth attributes. Thus, the maximum plant height was observed in N4 (100 kg N/acre), having plant height 193.92, 195.24 and 192.79 cm in first, second and third cutting, respectively, which was followed by the treatment N3 (75 kg N/acre), having 179.70 cm in first cutting, while second and third cutting have same plant height 168.62 cm. The exception was the plant population showed non significant behavior in second and third cutting while number of leaves per plant in second cutting only and protein % in third cutting showed non significant difference with nitrogen application.

The work aimed to evaluate the effect of irrigation with magnetically treated water on development, growth, and yield of the scarlet eggplant (Solanum gilo Raddi) cv. Morro Grande, in two growing seasons (autumn and spring). A completely randomized design in a 3x2 factorial scheme with three replications for the first growing season and 2x2 with five replications for the second growing season was used. Each experimental unit consisted of four plants spaced 0.75 m between plants and 1.00 m between rows. Factors consisted of irrigation using magnetically treated water, untreated water, three replacement of the crop evapotranspiration (50%, 75%, and 100% ETc) for the first growing season and two replacement of the crop evapotranspiration (75% and 100% ETc) for the second growing season. Stem diameter (millimeters), plant height (centimeters), shoot dry matter (grams), first flower and fruit (accumulated degree-days), number of fruits, fruit yield per plant (grams), and average fruit mass (grams) were evaluated. The water with magnetic treatment provided better results for the development variables, first flower, and first fruit in the second growing season. However, for the variables, stem diameter, plant height, shoot dry matter, fruit yield, and number of fruits, only the replacement irrigation depth factor obtained higher values for the 100% ETc than water-deficit treatments.

An experiment was conducted at the Vegetable Research Farm of the National Horticultural Research Institute, Ibadan, Oyo State, Nigeria, in the rain-forest agro-ecological zone in 2016 and 2017 to determine suitable cropping systems to increase the yield of okra. The seed of okra (Abelmoschus esculentus (L.) Moench), cv. LD-88, was planted at a spacing of 60 ? 40 cm as an intercrop and monocrop to produce an average density of 4.2 plants?m-2; the intercrops cowpea (Vigna unguiculata (L.) Walp.), var. Ife brown, and peanut (Arachis hypogaea L.), var. Kampala, were planted to provide average densities of 5.6 plants?m-2, 4.2 plants?m-2, 3.3 plants?m-2 and 2.7 plants?m-2. Data were collected on plant height, number of leaves, leaf area, stem diameter and fruit yield of okra. Year affected plant height, number of leaves, leaf area, stem diameter and fruit yield of okra intercropped with legumes at different densities. Legume densities affected plant height, number of leaves, stem diameter, leaf area and fruit yield. The interaction of year ? legume densities affected plant height, number of leaves, stem diameter, leaf area and fruit yield of okra. Intercropping okra with peanut at the density of 2.7 plants?m-2 enhanced its growth and yield and appeared to be the best configuration for these crops.
