YIELD AND QUALITY OF SELKIRK WHEAT SWATHED AT DIFFERENT STAGES OF MATURITY

Mwangi PG, Gachuiri CK, Mbugua PN. 2017. Effect of growth stage on fodder yield and quality of dual purpose sorghum. Trop Drylands 1: 100-104. Improved Dual Purpose Sorghum (IDPS) (Sorghum bicolor-Var Ikinyaruka) were yielded at six physiological growth stages to evaluate the impact of growth stage on crop and feed quality. Six treatments based on sorghum growth’s physiological stage were randomly administered to the plot in a block and replicated three times. The treatments were IDPS yielded at bloom stage (PS1), soft dough stage (PS2), hard dough stage (PS3), physiological maturity stage (stalks with grains), (PS4), physiological maturity stage (stalks without grains) (PS5), and 1 month post grain reap (PS6). The parameters monitored were Dry Matter (DM) crop, Crude Protein (CP), Neutral Detergent fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL), In vitro Dry Matter Digestibility (IVDMD) and shoot count. The highest DM crop (18.0 ton/ha) was achieved at PS4 secernated with 8.69, 12.75, 16.27 17.04 and 13.04 ton/ha for PS1, PS2, PS3, PS5 and PS6, respectively. CP reduced with maturity from 8.6 at PS1 to 7.98, 7.96, 7.61, and 6.77 to 6.72 at PS2, PS3, PS4, PS5 and PS6 respectively. NDF and ADF at PS1, PS2, PS3, PS4, PS5 and PS6 were 54.4, 60.8, 65.71, 65.93, 66.73 70.3 and 27.93, 35.96, 41.98, 41.97, 42.04, 46.05 respectively. ADL was 3.44, 5.03, 7.38, 7.39, 7.42, and 8.3 for PS1, PS2, PS3, PS4, PS5 and PS6 respectively. Highest fodder IVDMD of 60.72 was at PS1 secernated with 60.12, 54.73, 53.82, 53.56 and 45.75 achieved at PS2, PS3, PS4, PS5 and PS6 respectively. The PS3 growth stage yielded in fodder material with highest nutritive value while highest fodder yields were achieved at PS4. Reaping at PS5 supplied both fodder and grains for livestock and human consumption respectively. It was proven that crop and quality of IDPS were affected by age at reaping time.

Field evaluation of fall armyworm, Spodoptera frugiperda (J. E. Smith) feeding on yield and quality of bermudagrass, Cynodon dactylon (L.) Pers., var. ‘Alicia’, was studied during the 1983–1984 growing season. Yield losses of ‘Alicia’ ranged from 0.3 to 0.9 metric ton per ha when plots were infested with population densities of 1.1 to 9.9 larvae/0.1 m2, respectively. ‘Alicia’ was more tolerant to fall armyworm than ‘Coastal’ as indicated by lower damage ratings and losses in forage quality.

The percentage point for the determination quality of head point is 73,49%, broken grainsabout 13,92%, and 12,34% graing roats. The quality of rice milled varieties inpago Unsoed 1 includelow. The lower of rice quality is due to the low of head rice percentage, while the percentage ofbroken grain sand high graing roats. Rice milled yield about 51,23%

Rice crops are susceptible to disease, which causes large yield losses in many Asian countries. The influence of disease incidence and severity on grain yield and quality of the rice (Oryza sativa L., cv. BRRI dhan29) was investigated in three different locations of Chief Farm Superintendent’s (CFS) farm viz. Near Weather Yard (location-1), Near Agronomy Farm (location-2) and Near CFS farm office (location-3), Bangladesh Agricultural University (BAU), mymensingh, Bangladesh during boro season. In location-1, both brown spot and sheath blight were recorded whereas in location-2 and in location-3 only brown spot was recorded. Severity of brown spot was lowest at the location-1 and the highest at the location-3. Combined incidence of brown spot and sheath blight decreased the yield considerably whereas brown spot did not alone. Maximum severity of sheath blight was observed both in flowering and soft dough stage and minimum at maximum tillering stage. The lowest infection index of brown spot was obtained at maximum tillering stage and the highest infection index was obtained at soft dough stage whereas maximum and minimum infection index of sheath blight of rice were recorded at soft dough stage and maximum tillering stage, respectively. Aparently healthy seeds, spotted seeds, discoloured seeds, deformed seeds and chaffy grains were found among the three locations. Germination percentage was highest in healthy seeds compared to other category seeds. Alternaria padwickii, Alternaria tenuis, Bipolaris oryzae, Curvularia lunata and Fusarium semitectum were found to be associated with the seed. The highest and lowest occurrence of A. padwickii, A. tenuis, B. oryzae, C. lunata were recorded from chaffy grains and from healthy seeds, respectively. It is suggest that disease incidence and severity was gradually increased with the age of the plant and reduced yield and quality of BRRI dhan29. Int J Appl Sci Biotechnol, Vol 4(3): 311-317

Studies were carried out to evaluate the influence of post harvest processing conditions on yield and quality of ground turmeric. Rhizomes were peeled, cooked (autoclave or immersion) in water or alkaline media, sliced, dehydrated, ground, sieved, packaged in polyethylene bags and stored for 60 days at room temperature. Yields ranged from 9.84 to 14.51 g of powder/100 g of rhizome with moisture varying from 8.84 to 9.86 g/100 g. Peel removal caused 30% mass loss but the powder obtained had higher intensity of yellow and red. Cooking caused a reduction in dehydration time and provided a powder with lower moisture content, higher levels of curcuminoid pigments and higher Hunter CIE L*, a* and b* values. Cooking by immersion provided higher quality powder compared to autoclave. Use of alkaline media resulted in a product with lower curcuminoid content, and higher intensity of yellow. There was no change in pigment and colour characteristics during storage.

Abstract. The aim of this study was to determine the optimal harvest time to achieve maximum milled rice yield and quality of white rice in some newly introduced Italian rice varieties grown under agro-ecological conditions in the region of Kocani town, Republic of North Macedonia. During the 2014 and 2015, fourteen rice varieties were cultivated to estimate the milled rice yield and broken kernels from three different harvest times. From each rice variety, samples with moisture content between 20-22% (I variant), 18-20% (II variant) and 16-18% (III variant) were taken. From the third harvest variant the highest percentage of milled rice yield (65.23%) was obtained but also the highest rate of broken kernels (12.79%). From the remaining two harvests, almost identical milled rice yields were received (64.19% from the first variant and 64.33% from the second variant), but in terms of broken kernels, there were significant differences. The optimum moisture content during the harvest in order to obtain maximum yield and quality of milled rice ranged from 18% to 20%. The varieties Arsenal, Sprint and Mirko had the most favorable values for milled rice yield and broken kernels.
