Não preferência para alimentação e antibiose em cultivares de amendoim a Stegasta bosquella (Chambers) (Lepidoptera: Gelechiidae)

This work aimed to evaluate the attractiveness, non-preference for feeding and antibiosis in straight and runner growth habit peanut cultivars to Stegasta bosquella (Chambers). Eight cultivars were evaluated, four of straight growth habit (IAC Tatu, IAC 22, IAC 8112 and IAC 5) and four of runner growth habit (IAC Runner 886, IAC 147, IAC 125 and IAC 503). Free-choice and no-choice feeding tests were performed, using pairs of overlapped leaf discs with 1.0 cm diameter, which were placed in Petri dishes where third instar larvae of S. bosquella were released. The attractiveness to the larvae was assessed in predetermined times, in addition to the dry mass consumed. In the antibiosis assay, the biological parameters were evaluated: period and viability of larvae, pre-pupae, pupae, and total, weight of larvae and pupae, sex ratio and longevity. None of the runner growth habit cultivars exhibited non-preference for feeding-type resistance. Among the straight growth habit cultivars, IAC 5 and IAC 22 were the least attractive and consumed in the free-choice feeding test, and IAC 5 and IAC 8112 were the least attractive in the no-choice test. The runner growth habit cultivars IAC 147 and IAC Runner 886 affected the larval survival of S. bosquella, exhibiting antibiosis-type resistance. For the straight growth habit cultivars, IAC 22 and IAC 8112 affected the larval viability, presenting antibiosis-type resistance. The straight and runner growth habit cultivars did not influence the biological parameters of weight of pupae, sex ratio and longevity of S. bosquella.

Acúmulo de matéria seca e macronutrientes por cultivares de sorgo sacarino

Nutrient accumulation curves help us understand the nutritional demands of a crop. The aim of this study was to evaluate the growth and accumulation of macronutrients by the sweet sorghum cultivars CVSW80007, CVSW80147, CVSW82028, CVSW82158. The experiment was conducted in a renewal sugarcane ratoon area at Uchoa county, SP, being deployed in January 2012. The plants were collected in 15 days intervals from the 10th after emergence (DAE). The greatest content of dry matter, N, P, Mg and S, was due to by the CVSW82028 cultivar, while the CVSW82158 extract the greatest amount of K and the CVSW80147 of Ca. The stalks represented the highs percentage of dry matter and nutrient content, except nitrogen and phosphorus, in which grains corresponded to the higher percentage of total absorption. The CVSW80007, CVSW82028 and CVSW82158 cultivars showed the following decreasing nutrient extraction N>K>Ca>Mg>P>S and the CVSW80147, K>N>Ca>Mg>P>S. Considering only the stalks harvest, the decreasing nutrient exportation is the same for all cultivars: K>N>Ca>Mg>S>P. Whereas the decreasing nutrient exportation sequence considering stalks and grain harvest is the following for the CVSW80007, CVSW80147 and CVSW82158 cultivars: K>N>Ca>Mg>P>S and K>N>Ca>Mg>P>S for the CVSW82028.

Desempenho agronômico de cultivares de cevada cervejeira sob diferentes lâminas de irrigação

The research work aimed to evaluate the performance of barley cultivars under different irrigation depths in Brazilian Cerrado. The experiment was conducted in a split plot completely randomized design, with irrigation depths (50, 75, 100 and 125% of crop evapotranspiration) in the plots and barley cultivars (BRS Sampa, BRS Manduri and BRS 195) in the split-plots, with four replications. Barley cultivars were different regarding number of tillers per plant, number of spikelets per spike, and root depth. The maximum yields for BRS Sampa, BRS Manduri and BRS 195 were 5,848; 5,449; and 4,767 kg ha(-1), respectively. BRS Sampa showed a value 17% higher than the yield reported by the holder. The irrigation depth affected all the agronomic traits. It is recommended BRS Sampa for Brazilian Cerrado, that didn't differ from other cultivars and was developed in region of similar climate; with replacement of 100% of crop evapotranspiration.

Produtividade, teor foliar e exportação de nutrientes em cultivares de batata

The right choose of the cultivar influences greatly the potato yield. It is very important to know its agronomic behavior in the region where it is planted, as well its nutritional status, in order to supply the best package in the fertilization operations. In this work the tuber yield, the nutritional status of plants and the exportation of nutrients were studied in eighteen potato cultivars. A randomized blocks experimental design, with four replicates, was used. Mondial showed the highest total and commercial yields. The nutrient concentrations in fourth leaf of potato plant followed the decreasing order: N>K>Ca>P>Mg>B>Zn. The exportation of nutrients by the tubers followed the decreasing order: K>N>P>Mg>Ca. B and Zn had different behavior according the cultivars.
