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.

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.

At Yarwun (151.3˚E, 23.75˚S), Australia, papaya Hybrid 29 yielded twice as much fruit as Hybrid 11 and 30% more than Hybrid 13. The plots mulched with coarse grass hay yielded 50% more fruit than the plots with bare ground. The highest yielding treatment, Hybrid 29 + mulch, averaged the equivalent of 81 t/ha.year over the 16.5-month harvest period. The yields were achieved in spite of inadequate water supply due to drought and the loss of 877 plants from 1441 plant positions (4 plants per position) due to the 3 phytoplasma diseases; dieback, yellow crinkle and mosaic. Hybrid 29 produced higher yields than the other hybrids by flowering early on shorter plants with thicker stems and setting more fruit that commenced lower down on the stem. Hybrid 13 was intermediate in size and the amount of fruit setting between Hybrid 29 and Hybrid 11 but was the slowest to flower and set fruit. Hybrid 11 had the thinnest and tallest stems, flowered at an intermediate time between the other 2 hybrids and produced fewer flowers and fruit resulting in the lowest yield. Mulching increased stem height and thickness, promoted earlier flowering and increased fruit set, yield and average fruit weight

This study aims to determine the effectiveness of N2-fixing microbes contained in organic organic fertilizers at four levels of nitrogen fertilizer application in increasing the performance of oil palm seedlings. The experiment was carried out in the form of an experiment using a Randomized Block Design with 2 factors: organic organic fertilizer and nitrogen fertilizer. The first factor with three levels of treatment, namely without organic biological fertilizer, Organic fertilizer from cow dung (Agro Flower) 1 g / kg of Soil and Organic organic fertilizer (Biost) 1 g / kg of Soil. While the second factor consists of four levels, namely without N fertilizer, N fertilizer 50% of the standard dose, N fertilizer 100% of the standard dose, and N fertilizer of 150% of the standard dose. Each treatment was tested on 4 oil palm seedlings and repeated 3 times, so that 144 experimental plants were obtained. The observations made were the variable plant performance includes plant height, number of leaves, and stem diameter. Variants of plant nutrient levels included total N nutrient levels, P nutrient levels, and K nutrient levels. The results showed that N-inhibiting microbes contained in organic organic fertilizer increased plant height and stem diameter significantly in oil palm nurseries. The use of a 100% dose of N fertilizer together with organic biofertilizers shows the best crop performance results.

This work evaluated the development of colored cotton submitted to irrigation water of different salinity levels and organic matter doses from tanned manure. The experimental design was completely randomized in a 4 x 4 factorial scheme with 3 replications, totaling 48 experimental plots. The factors studied were 4 doses of organic matter (1, 4, 7 and 10%) and four levels of irrigation water salinity (0.26; 1, 2 and 4 dS m-1). The variables analyzed were plant height, stem diameter, number of leaves, number of fruits and fresh shoot mass. Significant effect of organic matter was observed on all studied variables, with a positive response on the increase of all variables as a function of increasing doses of organic matter. The isolated effect of salinity was significant for all parameters evaluated, except for the number of leaves, with significant reductions of 6.03; 3.27; 5.23; 6.94% in the parameters: plant height, stem diameter, number of fruits and shoot fresh weight respectively, for each unit increase of irrigation water salinity. The interaction between the variation sources studied had a significant effect only for fresh shoot mass, where the highest average for this parameter was observed at 10% organic matter dosage at irrigation water salinity level of 1.0 dS m-1.
