The effects of plant spacing and nitrogenous (N) fertiliser on the yield and plant conformation of Chinese cabbage were investigated for the michihili cultivar, Early Jade Pagoda, at Manjimup, Western Australia. The soil type was a sandy loam (7% gravel, pH 5.9) over clay at 60 cm. The experimental design included 4 plant spacings (25 by 25 cm, 30 by 30 cm, 35 by 35 cm, 40 by 40 em), and 6 rates of N fertiliser (0, 50, 100, 200, 300 and 400 kg N/ha). The highest marketable yields, 126.6 and 123.6 tha, were produced at the closest spacing, 25 by 25 cm, with N fertiliser rates of 200 and 300 kg/ha, respectively. Marketable yield for this spacing increased as N rate increased from 0 to 200 kg/ha, remained constant from 200 to 300 kg/ha and fell when the N rate was increased to 400 kg/ha. Soft rot damage was severe at the highest rate of N fertiliser and contributed to the reduced yield. The yield potential of Chinese cabbage was higher at close spacings than at the wider spacings. Plant height was not affected by any treatment, but plant width increased at the higher N fertiliser rates.

The effects of 3 common handling procedures and mishaps (dropping, compression and trimming) applied to Chinese cabbage cv. Yuki [Brassica campestris L. ssp. pekinensis (Lour.) Olsson] were compared to unstressed control cabbages. Heads were mechanically stressed by dropping from 50 cm onto a hard floor, by prolonged compression under 3 kg of weight before storage, or by repeated trimming of the outer leaves during storage. Cabbages were stored at 2°C for 9 weeks. Market quality of cabbages was not affected by the mechanical stresses, but storage for 9 weeks reduced marketable quality. Heads that were repeatedly trimmed produced less ethylene at the end of the storage period compared to the start, and less ethylene than the other treatments (due to the removal of outer senescing and rotting leaves); however, marketable yield was not improved.

Use Efficiency

Phosphate fertilization is indispensable for carrot cultivation, as it contributes to plant development, formation of marketable roots and higher yields. In this context, the objective of this study was to evaluate the production and nutritional efficiency of carrot cultivars under phosphate fertilization. The experiments were carried out from July to November 2016 and from June to October 2017, at the Rafael Fernandes experimental farm, District of Alagoinha, Mossoró, RN, Brazil. The experimental design was in randomized blocks, in a 4×4 factorial scheme with 4 replicates. The treatments consisted of the combination of carrot cultivars (Brasília, Planalto, Suprema and Nativa) with phosphorus (P) doses (0, 90, 180 and 270 kg ha-1 P2O5). The characteristics analyzed were: P content in the diagnostic leaf, plant dry matter, plant height, marketable and total yields, and the classification of cultivars for efficiency and response to phosphate fertilization. The increments promoted by phosphate fertilization were 64% in plant height, 444% in dry matter and 284% in marketable yield. The maximum marketable yield was obtained with doses from 186.8 to 243.5 kg ha-1, depending on the cultivar. The Native cultivar was classified as more efficient in the use of P.

Optimum plant spacing ensures proper growth and development of crops resulting in maximum crop yield and economic use of land. The objective of this study was to evaluate the effects of different planting spacing on the growth and yield of California Wonder Bell Pepper (Capsicum annuum) on sandy loam soil of The Gambia, from January to May 2018. The design used for this experiment was a Randomized Complete Block Design (RCBD) with four treatments (T1: 50 x 50 cm, T2: 50 x 40 cm, T3: 50 x 30 cm and T4: 50 x 20 cm) and three repetitions and the parameter of plant height, stem girth, number of leaves, fruit length, fruit circumference, individual fruit weight, yield per plant, and yield per hectare. The plant spacing had a significant effect on plant height, stem girth and the number of leaves of the growth parameters, whereas for the yield parameters, individual fruit weight, yield per plant and total biomass yield were found significantly in treatments with the highest plant spacing (50 x 50 cm). In conclusion, wider plant spacing (50 x 50 cm) boosts the plants to develop the maximum number of branches and fruits.

The experiment was conducted in the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2005 to December 2005 to study the effect of different levels of nitrogen and mulching on the growth and yield of Chinese cabbage. The tallest Chinese cabbage plant and spread of plant (43.12cm and 64.43cm) was recorded in 250kg N/ha and the shortest (36.15cm and 48.38cm) was recorded in 0 kg N/ha. The longest duration to start head formation (46.80 days) was recorded in 0 kg N/ha and the shortest (40.96 days) was recorded in 250 kg N/ha. The highest marketable yield per hectare of Chinese cabbage (120.06 ton) was recorded in 250 kg N/ha and the lowest yield (67.90 ton) was recorded in 0 kg N/ha. The highest Chinese cabbage plant, spread of plant (44.50cm, 58.28cm) during harvest period was recorded in black polythene mulch and the shortest plant and spread of plant (37.60cm and 49.58cm) was recorded in no mulch i.e. control. The highest days to start of head formation of Chinese cabbage (45.37) was recorded in no mulch and the lowest days (41.17) were recorded in black polythene mulch. The highest marketable yield per hectare of Chinese cabbage (123.27 ton) was recorded in black polythene mulch and the lowest yield (76.51 ton) was recorded in no mulch. In each and every case maximum growth and yield contributing characters and yield was observed in 250 kg N/ha and black polythene mulch and the reverse result was recorded in control condition i.e. no nitrogen and no mulch.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16845 Progress.

Nine chinese cabbage (Brassica campestris ssp. pekinensis group var. cephalata) cultivars were evaluated for petiole spotting (gomasho) and bacterial soft rot (caused by Erwinia carotovora ssp. carotovora) in 1999 and fifteen in 2000 and 2001. The cultivars were arranged in a randomized complete block design in a Granby sandy loam soil with six replications in 1999 and three replications in 2000 and 2001, at the Greenhouse and Processing Crops Research Centre, Harrow, Ontario, Canada. Plants were harvested in the fall of each year during two harvest periods, one for early-maturing cultivars, and one for late-maturing cultivars. At harvest, the percent bacterial soft rot, percent marketable heads, plant size, uniformity of harvest maturity, and the mean head weight were determined for each cultivar. The number and weight of spotted leaves was determined by rating (0 to 5 scale) each leaf. Petiole spotting was also rated following storage at 2 °C (36 °F) and 89% ± 5% relative humidiyt for 3 to 4 weeks in 1999 and 2000. `Yuki', `Manoko', and `Summer Top' had lowest losses from bacterial soft rot while `Akala', `Ohken 75', `Spring Flavor', and `Yuki' had low levels of petiole spotting. Cold storage increased the incidence of the spotting disorder for most cultivars.

Origin of SeedsAbstract. Research on the Effect of Nasa Liquid Organic Fertilizer Concentration and Planting Distance to Growth and the Result of Red Onion (Allium ascalonicum L). The Origin of Seeds, has been done in the Experimental Garden and Horticultural Laboratory of the Faculty of Agriculture, Syiah Kuala University of Darussalam Banda Aceh. This study starts from January to June 2016. This study aims to determine the effect of Nasa liquid organic fertilizer concentration and plant spacing on the growth and yield of shallot crops, and the presence or absence of interaction between the two factors. The design used in this research is Randomized Block Design The factorial pattern consists of 2 factors with 3 x 3 pattern. The first factor is the concentration of liquid organic fertilizer Nasa and the second factor is plant spacing. The parameters observed were plant height of 20, 40, 60 HSPT, number of leaves aged 20, 40, 60 HSPT, wet weighted weights, dry weighted weights, tuber weight, tuber number, tuber diameter and yield potential. The results showed that the concentration of Nasa liquid organic fertilizer had very significant effect on plant height of 20 HSPT, wet trimmed weight, dry weighted weight, dry bulb weight, tuber number, yield potential, and significant effect on plant height of 40 HSPT. The best growth and yield is found at a concentration of 5 ml / L of water. Plant spacing has a very significant effect on plant height of 40 HSPT, number of leaves aged 40 HSPT, weight of dry bulb, yield potential, and significant effect on dry-weighted weights. Growth and yield of best plants are found at plant spacing of 15 cm x 15 cm. There is a very real interaction between the concentration of Nasa organic liquid fertilizer with plant spacing to plant height of 20 HSPT, as well as the apparent interaction of wet weighted weights, dry weighted weights and yield potential. The best interaction was obtained by a combination of the treatment of concentration of liquid organic fertilizer Nasa 5 ml / L of water with spacing of 15 cm x 15 cm.

<p>Maize (Zea mays L.) is the second most important cereal crop of Indonesia after rice. The productivity of corn in Central Java province in 2015 was increased that considered as relatively low. Maize productivitiy needs to be improved to supply the requirement of people through of plant spacing and use the hybrid maize varieties. The aims of study was to determine the effectiveness level of plant spacing, to test the best hybrid maize varieties, and test the combination of two treatments to optimize the yield potential hybrid maize. This study has been conducted from June until October 2017, at Desa Srimartani, Kecamatan Piyungan, Kabupaten Bantul, Daerah Istimewa Yogyakarta. This study was arranged in Split Plot Design consisting of two factors that have been researched, varieties (ABCD, EFGH, NK6172, P27 and DK77) and plant spacing (70 x 20 cm, 75 x 20 cm, and 75 x 25 cm). The results show that treatment of varieties mostly can increase all of variable analysis but there is no interaction on both treatment except plant height, fresh and dry biomass weight. Variable of plant height, tasseling and silking, cob weight with husk, cob weight without husk, kernel seeds weight per plot, 100 seeds weight, yields per hectare show that the highest average is variety of P27. While treatment of plant spacing has no effect because the interval between treatments plant spacing is too close therefore it shows insignificantly different result. The highest dry kernel product on variety treatment P27 (8,82 ton ha-1), followed by DK77 (8,53 ton ha-1), ABCD (8,50 ton ha1), NK6172 (8,34 ton ha-1), and EFGH (7,13 ton ha-1).</p>

Cultural Requirements

Broccoli (Brassica oleracea var. italica), a popular vegetable crop, has one of the most exacting climatic and cultural requirements, which limit its commercial production to a few favored locations. A field experiment was conducted at Mizoram University, Tanhril, Mizoram during winter of 2013/2014 to find out the effect of time of sowing on plant performance and yield of broccoli. Six sowing time was done viz. 17 October (T1), 24 October (T2), 31 October (T3), 7 November (T4), 14 November (T5) and 21 November (T6) with plant spacing of 45cm x 45cm. Yield and yield contributing characters were significantly influenced by the planting time. Highest average weight of marketable curd per plant (199.20 g) was obtained from T2, whereas lowest average weight obtained from T6 (75 g). The influence of planting time also showed significant difference on the calculated yield (tonnes per hectare) of broccoli, in which T2 showed highest marketable yield of 9.83 t/ha.
