Abstract

No. of bitstreams: 0 Previous issue date: 2021-03-29 The relevance of the castor bean plant in Brazil's agribusiness plan lies in the quality of the oil it produces. That is why, to improve its quality, there is interest in obtaining hybrid plants adapted to off-season growing conditions and with the appropriate characteristics for mechanized cultivation. This study was conducted to examine the premature growth of hybrid castor bean plants as a function of plant populations cultivated in the off season in the Nova Alta Paulista region of the state of Saõ Paulo. A randomized complete block design with a 3x4 factorial arrangement, three hybrid castor bean plants (AGIMA 110204, MIA, and TAMAR) and four individuals per linear meter (2, 4, 6, and 8), was adopted, and four replications were performed for each treatment. The seeds were sown on April 12, 2017, at the UNESP/FCAT research farm in Dracena, Saõ Paulo. Assessments on plant development and reproductive traits were made 138 days after emergence (DAE). The plants' height, number of racemes per plant, 100-grain weight, and SPAD chlorophyll reading in the treatments resulted in similar averages. The TAMAR hybrid presented the highest insertion point for the primary raceme and, along with the MIA hybrid, produced the largest racemes. The stem diameter of all the hybrids presented a linear decrease as the plant population increased along the line the seeds were sown. The grain yields of the hybrids were 1,784 kg ha-1 (TAMAR), 1,659 kg ha-1 (AGIMA 110204), and 1,547 kg ha-1 (MIA).

Abstract

Brazil is the largest Coffea arabica L. producer and exporter in the world market. In view of the need for nitrogen fertilization, the objective of this work was to evaluate the use of digital images of coffee leaves as a function of nitrogen concentration and cultivars, as well as to evaluate the most adequate sampling of this technique to predict leaf nitrogen. The experiment was set in a greenhouse, at UNESP - Experimental Campus of Registro-SP, using 12L pots with medium sand. A completely randomized design was adopted, in a 4 x 2 factorial scheme, with four concentrations of N (0, 50, 100 and 200 mg dm-3), and two coffee cultivars (Mundo Novo and Obatã), with ten replications. The variables evaluated were: hue, dark green color index (DGCI), leaf area and leaf nitrogen content. The hue and DGCI were influenced by N concentration, cultivar and are dependent on the day after treatment application and the number of leaves used. The use of five leaves per replication was more adequate to estimate leaf N content. Hue, DGCI and leaf area were higher in Obatã depending on the day after application of the treatment and N concentration. [ABSTRACT FROM AUTHOR]

Abstract

Made available in DSpace on 2022-04-28T19:29:58Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-09-30 The interest for pejibaye crops started to grow after the 70’s decade, due to the agronomic qualities, ecological, industrials and commercials. The São Paulo State is highlighted as one of the biggest pejibaye growers of the country, most concentrated at Vale do Ribeira. It was objectified with this work to evaluate characteristics of vegetative growth of plants as well as the ideal cutting time for stems in cultivation with different population densities, for the second year of cutting, aiming at the heart-of-palm yield of pejibaye. The experimental design was used in a 2x5 factorial, with treatments with five classes of cutting height (1,60 m, 1,90 m, 2,20 m, 2,50 m and 2,80 m) and two densities of plants (5,000 and 10,000 plants ha-1). The experiment was led on Campus Experimental de Registro UNESP’s farm. The analyzes were performed on march 16th and 17th of 2016 and September 01st e 19th of the same year. Stems of pejibaye at cutting height of 2,8 m and harvested in march obtained a larger number of leaves, a larger diameter of the stem in relation to the other heights and larger total amount of heart-of-palm produced. Stems with the same cutting height, but harvested in the month of September, provided greater production of minced hearts-of-palm, slice, thole and total amount of pejibaye heart-of-palm.
