Qualitative Changes

Fresh pepper {Capsicum annuum L.) production has a great tradition in Hungary. In 2014 fresh pepper was forced on 1600 ha, which reached approximately a 10 kg/m2 yield. While in case of tomato, which belongs to the Solanaceae family, the use of grafted plants is relevant today, the practice of grafted plants in the cultivation of hungaricum fresh pepper is a not so known and used method. Therefore, the main objective of the experiment was to study the qualitative changes in response to grafting and to determine the appropriate rootstock - scion combination. The experiment was set up in unheated plastic house at the research garden of Szent István University in Soroksár. Combination of two fresh pepper varieties SV 9702 (white type) and Karpex (kapia type) and two rootstocks Snooker and Capsifort were tested in soil and soilless culture. For soil culture the soil of the plastic house and for the soilless culture coconut fiber slabs was used. Grafted and non-grafted white type fresh peppers were placed at a row width and plant spacing of 110+40 x 33 cm (4 plants per m2) while kapia at 110+40 x25 (5.3 plant per m2). After the picking the Brix content was determined at the analytical laboratory of the department. From each repeat, 6 fruits were blended and measured with manual digital refractometer (PAL-1, ATAGO). After our studies both Snooker and Capsifort rootstock are recommended in combination of SV 9702 white type and Karpex kapia type fresh pepper in soilless culture.

Time Of Harvest

To test the potential suitability of ten tomato varieties in the Murrumbidgee Irrigation Area of New South Wales to mechanical harvesting, the yields from 'once-over' harvests were compared with the yields from a harvest consisting of four pickings at weekly intervals. In a second experiment the effect of plant spacing, time of harvest, and side-dressing with nitrogen fertilizer were studied for the most promising varieties from the first experiment. The varieties Roma 884, VF145-22-8, and VF145 held their crops for prolonged periods without deterioration and so showed potential for mechanical harvesting. High planting density gave the highest yields from a single picking, and later picking and nitrogen side-dressing also increased yield.

A field trial was conducted at Shika, Northern Nigeria to examine the effect of two plant spacings: 30 x 25cm (SI) and 60 x 25cm (S2), four phosphorus leves (75, 100, 125 and 150kgP.ha) and harvesting at 86, 100, 114 and 128 days after planting (DAP) on forage yield of La-blab purpureus cv. Highworth. Closer spacing significantly gave higher (P < 0.05) leaf, stem and total dry matter (DM) yields that wider spacing. Application of phosphorus fertilizer did not significantly (P > 0.p05) influence stem and total DM yield. Leaf DM yield was affected (P < 0.05) by the levels of fertilizer applied. Earlier harvest favoured leaf DM yield, while later harvests gave significantly (P < 0.05) higher stem and total DM yields. The contributions of stem towards the total DM yield increased with age of plant: 86 DAP (55%) < 100 DAP (71%) < 114 DAP (80%) < 128 DAP (89%). The data obtained suggest that a spacing of 30 x 25cm with the application of 100kg P/ha would suffice for satisfactory forage yield.

Consumption of sweetpotato (Ipomoea batatas) has increased in the past decade in part because of its nutritional and health attributes, and because of the availability and convenience of processed products. The sweetpotato processing industry is expanding and supplying more sweetpotato products than ever before. Unlike the medium-sized roots (U.S. no.1) preferred for fresh market, large (jumbo) roots is accepted and in certain cases desired by the processing industry, and overall yield is preferred over strict sizing requirements and aesthetic appeal. Therefore, this study investigated the yield increase and grade proportions in response to plant spacing and extension of the growing period to improve profitability of the production system. Experiments with ‘Beauregard’ and ‘Evangeline’ sweetpotato were conducted in Mississippi and Louisiana during 2010 and 2011. Treatments consisted of a combination of early and late planting date and delay in harvest, in-row plant spacing, and row width. Yield increase was inconsistent with delaying harvest and appears to depend on environmental conditions at harvest late in the season. Marketable yield was consistently greater in early plantings than late plantings. Yield of U.S. no.1 grade was unaffected by delaying harvest regardless of planting date. Delaying harvest in early plantings contributed to increase jumbo-sized roots and marketable yield. The economic assessment of delaying harvest in early plantings indicated a gain in net benefit either when hand harvested for fresh market or field run bulk harvested for processing. Row width and in-row plant spacing had only a marginal effect on yield of canner grade (small-sized roots). The economic assessment of changing plant density indicated no gain in net benefit, which indicates that choice of plant density can depend on other factors.

High Yields

Mechanically harvested pickling cucumbers are a once-over destructive harvest system. Gynoecious hybrids are planted at high populations to obtain high yields and to concentrate maturity. Population, row width, plant spacing, and uniform emergence all affect yield and maturity. 65,000 plants/acre in 26 inch rows were found to optimize yield and provide the highest percentage of fruit at the desired uniform size.

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.
