Planting date plays important role in the growth, development and yield of maize. Optimum planting date has becomes a prime importance for higher crop production. The plant establishment as well as pest and disease incidence are affected by planting dates. Crop varieties respond differently to planting dates. Early or late planting dates on maize causes an array of morpho-anatomical, physiological and biochemical changes in plants, which affect plant growth and development and such changes may lead to a drastic reduction in yield. Maize growth and development involves numerous biochemical reactions which are sensitive to variance in weather parameters as affected by planting dates. Delayed planting dates affect traits namely anthesis silking interval, photosynthesis, physiological maturity and dry matter production due to reduction in cumulative interception of photosynthetically active radiation (PAR). Late planting dates cause higher non-structural carbohydrate concentration in stems at mid-grain filling stages due to low temperature exposure of crop limiting kernel growth and photosynthesis. The adverse effects of delayed planting dates can be mitigated by forecasting optimum planting dates through crop modeling experiments. This article summarizes various effects of planting dates on maize growth, development and yield parameters. This information may be useful for maize growers and researchers.

ABSTRACT: The presence of a compacted soil layer near the ground surface in paddy fields may limit the growth and development of soybean roots. The objective of this study was to evaluate different planting management systems and irrigation on growth and development of soybean root systems in lowland area. The experiment was carried out in 2013/14 and 2014/15 crop seasons in randomized complete block design with factorial treatment (3x2), with four replications. The treatments consisted of different planting management systems: sowing with double disc (A1); sowing with shank (A2) and deep tillage + sowing with double disc (A3), and irrigation: irrigated (D1) and non irrigated (D2). Planting management systems and irrigation influenced the growth of soybean roots. When double disc was used, roots have lower growth and increase in diameter. Use of shanks and deep tillage provide increased growth and development of soybean roots and greater depth distribution. An additional 55mm of irrigation during the V4 soybean development stage provides increased surface area and root volume in when the soil moisture reaches values below 60% of field capacity.

The article presents the results of three years of research on the study of the photosynthetic activity of Dicoccum plants (emmer) depending on the methods of agricultural technology (sowing time, predecessors, different levels of nutrition) in the conditions of gray forest soils of the middle Volga region. During the years of research, relatively favorable meteorological conditions were created for the growth and development of wheat of the willower (emmer). Observations, surveys, analyzes for the growth and development of wheat emmer made it possible to establish that in all the years of research, the dynamics of accumulation of dry matter to the phase of plant entry into the tube are not dependent on their predecessors, the time of sowing and food background is weak. As is known, during this period, the formation and enhanced growth of the root system and the formation of the generative organs take place. After the plants entered the tube before the beginning of the milky ripeness, an intensive increase in dry matter was observed, especially for the predecessor of one-year-old clover in the first term of sowing when applying the calculated rates of fertilizers. The collection of dry organic matter, the assimilation power of wheatgrass plants was higher in the first term of sowing according to its predecessor, one-year-old clover and vetch + oats to the green mass, regardless of the food background. The planting dates, as well as the precursors, have a significant impact on the dynamics of leaf surface growth and the increase in dry biomass. More favorable conditions for the photosynthetic activity on wheat crops, double-weeds (emmer) are created during early sowing of the precursors of one-year-old clover and vico-oatmeal mixture for green fodder, regardless of the food background.

Determinate, photoperiod-insensitive genotypes of pigeonpea, (Cajanus cajan) have the potential for production in the short growing season of the temperature region. A field study was conducted to determine the effect of three planting dates on the growth and development of this crop in Missouri. Seeds of four genotypes, ICPL 87 Isolation (85k), ICPL 85010, ICPL 85024 and ICPL 8304 were planted at three planting dates in 1990, May 1, May 15 and May 31. Germination of the earliest planted seeds was low but increased in the later planted ones. The earlier the planting date the longer was the time to flowering, but the earlier was pod maturity. The earliest planted group flowered within 78-110 days after planting. The genotypes in this group produced the highest fresh pod weights of 330-730 g/plant and the latest planted ones produced the least. Pod length, the number of seeds per pod and weight of 100 seeds had ranges of 5.1-5.9 cm, 3-4 seeds and 17-23 g, respectively and were unaffected by planting dates.

A field study was designed to determine the effect of planting date and cultivar on growth and yield of strawberries in the low desert. The study was conducted at the Univ.of Arizona, Citrus Agricultural Center, near Waddell. Treatments included two strawberry cultivars (Camarosa and Chandler) and three planting dates 20 Aug. and 8 and 22 Oct. 1997. There was no significant difference in fruit yield between cultivars. However, fruit number was significantly greater for `Chandler', and, therefore, fruit size was smaller than `Camarosa.' Yield was significantly higher for strawberries planted 20 Aug., with nearly four times the yield compared to the other planting dates. Results of this study suggest summer planting of strawberries in the low desert to produce economically viable yields.

A 2-yr study was conducted to determine the influence of early and late soybean [Glycine max(L.) Merr.] planting dates on the competitiveness of velvetleaf (Abutilon theophrastiMedic). Velvetleaf was planted at densities of one plant per 61 and 30 cm of row, and competition ranged from 4 weeks to full season. Soybean planting dates were mid-May and late-June. Velvetleaf emerging with soybeans in mid-May were twice as competitive as those emerging with soybeans planted in late-June. A density of one velvetleaf per 30 cm of row competing full season reduced soybean yields 27% for the early and only 14% for the late planting date. The competitive difference was due to the short-day photoperiodic response of velvetleaf. Although the early growth stages of soybeans are more competitive than those of velvetleaf, 10 weeks after emergence velvetleaf competition reduced soybean growth and development. Velvetleaf does not appear to be a potential major problem in Arkansas for soybeans planted in June due to its photoperiodic response and late season competitiveness. However, the weed could present problems for soybeans planted early, especially when an early maturing variety is used.
