Nitrates Content

The evaluation of nutritional quality of Chinese cabbage and the effects of cultivar, weed incidence, plant density and growing season were observed in integrated cultivation system. Mean contents of analysed compounds were as follows: 6% of dry matter, 10% of crude fibre, (in mg/kg of f.m.): 2,199 mg K, 289 mg Ca, 146 mg Mg, 111 mg Na, and 316 mg of vitamin C. Mean content of nitrates reached the value of 647 mg/kg. A significant effect of cultivar on the content of all observed substances in cabbage heads excluding magnesium was thus confirmed; however, a decrease of nitrates was found in the treatment with higher plant density. Weed cultivation caused slightly (insignificantly) higher nitrates content in cabbage heads by 100 mg/kg. Growing season showed a significant effect on content of some evaluated compounds. Integrated cultivation of Chinese cabbage could be an adequate approach to ensure nutritionally valuable products with low nitrates content.

The effect of harvest period on the quality of storage roots and leaves of cassava cultivars was determined in an experiment carried out in a randomized complete block design with four replications in a split plot scheme, with five cultivars in the plots and ten harvest times in the subplots. The IAC 13 cultivar had the highest rate of dry matter accumulation in the storage roots and the Mico cultivar the lowest. The period of least dry matter content in the storage roots occurred later for the Fécula Branca, Mico and IAC 14 cultivars, and the minimum starch content in the storage roots occurred later for the Fécula Branca and Mico cultivars. In general, the IAC 13, IAC 14 and Fécula Branca cultivars had higher dry matter content in the storage roots, while higher starch content in the dry and fresh matter were obtained in the Fécula Branca cultivar. The crude protein content in the leaves decreased as the plant aged.

Hybrid Pennisetum

Dry matter accumulation in maize, hybrid pennisetum and mid- and late-season pearl millet were assessed following planting in mid-summer at Camden, New South Wales. Productivity was high in maize and hybrid pennisetum, the maximum above-ground rate of dry matter accumulation averaging 590 kg ha-1 day-1 for 20 days for maize in March 1975. Productivity was lower in the pearl millets which lodged in April of 1975 and 1976. Organic matter digestibility was superior in maize, phosphorus concentrations were higher in hybrid pennisetum and magnesium and calcium concentrations were the same in hybrid pennisetum as in maize. The concentrations of minerals would be generally too low to maintain highly-productive livestock if they were fed exclusively on these tropical forages.

AbstractTo avoid the negative impact of excessive fertilization on vegetable production, a decreased fertilization experiment was conducted in a multi-layer covered plastic greenhouse in 2017 to 2018. Treatments included no fertilizer (CK), traditional fertilization (TF), slow-release fertilizers (SRF), and decreased fertilization with slow-release fertilizers (DSRF). Results showed that the SRF and DSRF increased leaf length (13% and 8.3%) and chlorophyll content (7.1% and 8.2%) of Chinese chives compared to TF. Similarly, DSRF was found to increase the accumulation of dry matter accumulation of roots (22%) and the dry matter accumulation of shoots (36%) of Chinese chives. Flavonoid, soluble sugar, and soluble protein content were enhanced by 18%, 8.5%, and 4.6%, respectively, in DSRF compared to TF. Nitrate content of the SRF and SRFR decreased significantly by 26% and 35%, respectively. In addition, there was a significant increase in soil nutrient and enzyme activity in the middle and late harvest of Chinese chives under DSRF compared to TF, and there was a high correlation between soil nutrients and the quality of Chinese chives. The available P and total P content significantly differed among the different greenhouse soil samples, and this significantly affected the quality of Chinese chives. The content of available P and total P in greenhouse soil was 125.07 g kg−1 and 1.26 mg kg−1, respectively. Optimal quality was obtained. Hence, the application of DSRF promoted the growth of Chinese chives and improved soil fertility, thereby enhancing the productivity and quality of Chinese chives.

O tipo de fertilizante e a forma de aplicação deste, interferem diretamente em sua qualidade. O objetivo com o presente trabalho foi de avaliar a adubação com fertilizantes de liberação gradual ou a fetirrigação, na implantação de gramado esportivo. O experimento foi em Botucatu, SP. O delineamento foi em blocos ao acaso, em parcelas subdivididas, com grama zoysia Zeon e bermuda Celebration, como parcela principal, e cinco manejos de adubação (sem adubação; fertirrigação; com fertilizantes convencionais; com fertilizante de liberação lenta; com fertilizante de liberação controlada), nas subparcelas, de janeiro a junho de 2018. As características avaliadas foram: taxa de cobertura verde, índice de coloração verde escuro, índice de grama, altura do gramado, fitomassa da matéria seca das aparas, do estolão, rizoma e da raiz, e número de cortes. A grama Zeon apresentou maior taxa de cobertura verde e maior acúmulo de fitomassa de estolões e rizomas que a Celebration. A grama Celebration apresentou maior índice de grama e de cor verde escuro que a Zeon. O manejo com fertilizante convencional proporcionou os maiores valores das características de crescimento nas duas espécies, contudo exigiu mais mão de obra.   Palavras-chave: adubação, Zoysia, bermuda, campos esportivos.     KAMIMURA, L.

FERTIGATION AND GRADUAL RELEASE OF FERTILIZERS FOR PLANTING OF SPORTS TURFGRASS     2 ABSTRACT   Sports turfgrass requires care to show good development and "playability". The type of fertilizer and the way of application of this fertilizer directly interfere with its quality. The objective of the present work was to evaluate fertilizers of gradual liberation (slow or controlled) and fertigation in order to obtain higher quality of sport turfgrass. The experiment was conducted in Botucatu, SP, Brazil. The design was in randomized blocks, in subdivided plots, with Zeon and Celebration turf, as main plot, and five managements of fertilization (1. without fertilization, 2. fertigation, 3. fertilization with conventional fertilizers, 4. fertilization with fertilizer and 5. fertilization with controlled release fertilizer), in the subplots, and four replications, from January to June. The results were evaluated using the Green Index Rate, Dark Green Color Index, Grass Index, turfgrass height, Dry matter Phytomass, stolon, rhizome and root dry matter, root length and number of mowing. Zeon grass presented higher green cover rate, as well as higher dry matter accumulation of stolons and rhizomes than Celebration. Celebration grass presented grass index and dark green color index higher than those of Zeon. Management with conventional fertilizer provided the highest values of growth characteristics of the two species, but required more cuts and labor for application.   Keywords: fertilization, zoyziagrass, bermudagrass, sports fields.

Tuber Production

An experiment was conducted at Divyapuri of Nawalparasi district in the western Terai during winter season 2008/09. There were 16 treatments consisting of two mulch levels (mulched and no mulch) as main plot, two varieties (Kufri Chipsona-1 and Kufri Chipsona-2) as sub plot and four levels of potash (0, 50, 100 and 150 kg K2O /ha) as sub-sub plot arranged in split-split plot design with four replications to evaluate the effect of these treatments on tuber production and their effect on quality of potato chips. The result showed that plant height, number of shoot per plant, dry matter accumulation, number and weight of tuber per plant and tuber yield were significantly higher in Kufri Chipsona-2 than in Kufri Chipsona-1. Lower reducing sugar and browning percent of chips and higher dry matter content and chips recovery were also recorded in Kufri Chipsona-2 compared to Kufri Chipsona-1. Simple economic analysis on gross return, net return and B/C ratio were higher in Kufri Chipsona-2. However, increasing levels of potash from 0-150 kg K2O /ha increased the dry matter accumulation, LAI, number and weight of tuber per plant. The result also showed that as the level of potash increased there was a decrease level of reducing sugar and browning of chips as well. On the other hand, higher potash levels increased the percentage of fat content and recovery of chips. Also increase in potash levels resulted to increase in gross return, net return, and B/C ratio. There was no effect of mulching levels on tuber yield and quality of chips recovery. Of the two varieties, Kufri Chipsona-2 with 100 kg K2O/ha was found suitable for tuber production and recovery of chips quality.

The objective of this research is to study the maturation process of buffel grass cv. Aridus seeds in order to determine their best harvest season, aiming at maximum seed quality. During the inflorescence emergence phase, they were labeled upon showing from five to ten inflorescences emerged per m2. The first seed harvest was done 20 days after inflorescence emergence, and the other harvests were done at 5-day intervals, totaling six harvests. In each harvest season, the seeds were assessed as to water content, dry matter mass, germination, first germination count, seedlings emergence, emergence speed index, and electrical conductivity. The physiological maturity of buffel grass seeds (maximum germination, vigor and dry matter accumulation) occurs from 38 to 42 days after inflorescence emergence, moment when harvest must be done.

Yield And Quality

A field experiment was conducted during kharif 2014 at students’ farm of Chaudhary Charan Singh Haryana Agricultural University, college of agriculture, Kaul (Kaithal). The experiment consisted of four transplanting dates (June 15, July 5, July 25 and August 15) in main plots and six weed control treatments in sub plots treatments consisted of pre-emergence application of pretilachlor, oxadiargyl alone and sequential application of pre and post emergence herbicides viz., pretilachlor fb bispyribac, oxadiargyl fb bispyribac, weed free check and unweeded check. Based on research investigation it was observed that early transplanting dates (June 15 and July 5) produced taller plant, higher tillers/m2 and crop dry matter accumulation at all growth stages. Early transplanting produced significantly higher number of effective tillers/m2 (263) along with higher number of filled grain/ panicle (85) than delayed planting (July 25 and August 15). The 1000-grain weight was not affected by time of transplanting. The highest grain yield (4363 kg/ha) was recorded under June 15 transplanting which was statistically at par to the grain yield (4058 kg/ha) obtained under July 5 transplanting. Among the weed management practices tried, weed free check resulted in the highest values of plant height (104.2 cm), tillers/m2 (305), crop dry matter accumulation (964 g/ m2), effective tillers/m2 (271), grains length (8.5 cm), filled grains/panicle (86.3) as well as grain (4516 kg/ha) and straw yield (5506 kg/ha) which were however, comparable to pre-emergence application of oxadiargyl followed by bispyribac-sodium applied at 25 DAT and pretilachlor followed by bispribac-sodium at 25DAT.
