Three commercial sugarcane varieties such as NCO-334, B52-298 and N14 were grown at Finchaa Cane Plantation, Ethiopia to determine the optimum harvest age for cane and sugar yields. Treatments consisted of factorial combination of varieties and five levels of harvest age were arranged in Randomized Complete Block Design with three replications. The varieties differed in stalk diameter and weight, and millable stalk number. Improvements in internodes number, stalk diameter and weight were increased with harvest age whereas internodes length and millable stalk number decreased with delay in harvesting. Varieties produced better juice quality in canes harvested at 17 months. NCO-334 attained its peak superior quality at the age of 15 months. This preliminary data on some indicator quality parameters imply that NCO-334 could be harvested at 15 months age in order to maximize sugar yield. However, more experiments are required to confirm the effect of harvesting time and variety on cane and sugar yield. Therefore, more research on detecting other quality parameters focusing on cane and sugar yield is recommended.

The quality of wheat is a pre-eminent factor in the criteria for commercialization of this cereal, and several parameters contribute to the evaluation of wheat quality. The objective of this study was to verify the effects of nitrogen fertilization on the cover and the environment for wheat cultivars and the effects on the industrial quality of the grain. Furthermore, we sought to identify correlations between the parameters of industrial quality. Experiments were conducted in Londrina for 2 years, in two distinct environments (A1 and A2). The experimental design was a randomized complete block design with four replications. The cultivars IPR Catuara TM, BRS Gaivota, Quartzo, and CD 120 were evaluated with different forms of nitrogen management: N1, without N in coverage; N2, 60 kg ha-1 of N in the form of urea at the beginning of tillering; N3, 80 kg ha-1 of N in urea formulation (60 kg ha-1 in tillering and 20 kg ha-1 in booting); N4, 100 kg ha-1 of N in the form of urea (60 kg ha-1 in tillering and 40 kg ha-1 in booting); N5, 80 kg ha-1 of N (60 kg ha-1 of N in the form of urea at the beginning of tillering, and 20 kg ha-1 of N in the form of ammonium sulfate in booting); N6, 100 kg ha-1 of N (60 kg ha-1 of N in the form of urea at the beginning of tillering, and 40 kg ha-1 of N in the form of ammonium sulfate in booting). Further, we evaluated grain yield, protein content, sedimentation volume with sodium dodecyl sulfate, and parameters of alveograph and farinograph. Nitrogen fertilization did not influence industrial quality parameters. The stability of the mass was influenced by the isolated effects of cultivars and the environment. The interaction of cultivars and environments influenced the parameters of alveograph and water absorption of the mass. The higher the protein content, the lower the stability of the mass, independent of the cultivar.

Abstract The objective of this work was to evaluate the development and quality of clonal seedlings of teak (Tectona grandis) grown in substrate with two types of biochar. The assay was carried out in a randomized complete block design, with ten treatments and four replicates: CS, commercial substrate, composed of pine bark and vermiculite at a ratio of 4:1; NS, nursery substrate composed of carbonized rice husk and coconut fiber at 1:1; and the remaining treatments were composed of the inclusions of biochar (BC) or activated biochar (BCA) in the CS, at the proportions of 25, 50, 75, and 100%. The development and quality parameters of seedlings were evaluated 90 days after striking the minicuttings in the substrates. BCA substrate additions at 25, 50, and 100% allowed for a development of height and stem diameter comparable to that of the NS. Biochar without the activation procedure does not improve quality parameters of seedlings, in comparison with the commercial substrate. The use of 25% activated biochar added to the commercial substrate is enough to improve seedling growth performance to the same level as that provided by the already validated NS.

PRODUCTION AND QUALITY OF MARANHÃO PUMPKIN UNDER INFLUENCE OF WATER DEPTHS AND NITROGEN DOSES     2 ABSTRACT   The pumpkin crop is becoming outstanding in  the world scenario due to growing concern with the issue of food challenge and its production characteristic associated with small properties. There is little information in the literature about pumpkin responses to irrigation management associated with nitrogen fertilization. The objective of this work was to evaluate productive performance (number, fresh weight, dry weight and productivity) and quality parameters (diameter, length, pulp thickness and ° Brix of the fruits) of pumpkin culture under irrigation levels associated with doses of nitrogen fertilizer. A randomized complete block design was used in subdivided plots, where the nitrogen dose factor (50; 70; 100; 125% kg of N ha-1) was inserted in the plots and in the subplots, irrigation depths  (50; 75; 100; 125% of evaporation measured in tank class A - 'ECA') with four replicates. The research was conducted in the experimental area of the Meteorological Station belonging to the Federal University of Ceará. The maximum productivity reached was 4269.6 kg ha-1 obtained with the combination of water blade of 444.10 mm (122.5% of ECA) and nitrogen level of 33.65 kg ha-1 of N (112.16% of the recommended N).   Keywords: milk jerimum, fertilization, irrigation management.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.

Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen resulted in higher seed yield per area, but the plant spacing did not affect this characteristic. Manual pollination, using a whole anther, did not differ from natural pollination in relation to seed yield and quality.
