Refined nutrient delivery systems are important for environmentally friendly production of cut flowers in both soil and hydroponic culture. They have to be closely orientated at the actual nutrient demand. To solve current problems, express analysis and nutrient uptake models have been developed in horticulture. However, the necessity of relatively laborious analysis or estimation of model input parameters have prevented their commercial use up to now. For this reason, we studied relationships between easily determinable parameters of plant biomass structure as shoot height, plant density and dry matter production as well as amount of nitrogen removal of hydroponically grown year-round cut chrysanthemums. In four experiments (planting dates 5.11.91; 25.3.92; 4.1.93; 1.7.93) with cultivar `Puma white' and a fixed plant density of 64 m2, shoots were harvested every 14 days from planting until flowering, with dry matter, internal N concentration and shoot height being measured. For each planting date, N uptake (y) was closely (r2 = 0.94; 0.93; 0.84; 0.93, respectively) related to shoot height (x) at the time of cutting and could be characterized by the equation y = a * × b. In the soilless cultivation system, dry matter concentrations of N remained constant over the whole growing period, indicating non-limiting nitrogen supply. In agreement with constant internal N concentrations, N uptake was linearly related (r2 = 0.94 to 0.99) to dry matter accumulation. It is concluded that shoot height is a useful parameter to include in a simple model of N uptake. However, in consideration of fluctuating greenhouse climate conditions needs more sophisticated approaches including processes such as water uptake and photosynthetically active radiation.

An experiment was conducted with a local cultivar of garlic to study the effects of planting date and gibberellic acid on the growth and yield of garlic at the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during November 2001 to April 2002. Early planting influenced the plant height, leaf number, bulb diameter and total dry matter. With the delay in planting time starting from November 7, the yield was chronologically reduced in later plantings. Significantly the highest bulb yield (2.67 t/ha) was recorded when planting was done on November 7 and lowest yield (0.92 t/ha) was obtained from December 22 planted crop. Bulb yield was higher in control plants than those of GA3 treated plants. The interaction effects of planting date and different concentrations of GA3 differed significantly in respect of plant height, number of leaves, bulb diameter and dry weight of roots, leaves and bulbs and yield of garlic.

Dry matter yield is an objective indicator of assessing the productivity of corn hybrids grown for silage and green fodder. The aim of the work was to identify optimal planting dates to obtain maximum yield of dry matter at the late milk stage of development for hybrids of corn depending on groups of maturity under rain-fed conditions of the Crimean steppe zone. The sowing dates of the field experiment were on April 5th, 15th, and 25th. We studied hybrids of corn of different groups of maturity. Soil – chernozems southern low-humus. Meteorological conditions in 2016 were characterized by increased moisture availability (Selyaninov Hydrothermal Coefficient (HTC) 1.46). In 2017, severe drought was noted (HTC 0.34). Moisture availability was insufficient in 2018 and 2019 (HTC 0.79 and 0.78, respectively). In 2016-2019, the best planting date for hybrid ‘Nur’ was April 15th; the dry matter yield in the late milk stage was 6.69 t/ha. For the medium- early hybrid ‘Mashuk 220 MV’, the best sowing dates were April 15th and 25th; dry matter yield was 5.95 and 5.78 t/ha, respectively. Hybrid ‘Mashuk 355 MV’ demonstrated higher dry matter yield on April 5th and 15th (7.12 and 6.99 t/ha). However, the planting date of April 25th led to significant yield decreased (to 6.1 t/ha).

<p>One of the most important and sustainable cropping practice is intercropping. The study was conducted under field conditions in the arid Horqine sandy land in Baicheng District, Jilin Province, Northern China in 2011. A randomized complete block design with four replications was used. Treatments comprised different mono cropping and intercropping patterns, TO: sole cropping of oat, TOS-O: oat in the intercropping of oat and soybean, TOG-O: oat in the intercropping of oat and groundnut, TS: sole cropping of soybean, TOS-S: soybean in intercropping of oat and soybean, TG: sole cropping of groundnut, TOG-G: groundnut in the intercropping of oat and groundnut. In mono-cropping systems, oat mono-cropping obtained the highest dry matter and nitrogen accumulation in all growth stages. The maximum protein percentage in all stages except for ripening stage, were for groundnut mono-cropping. Although, the maximum organic matter in ripening stage was achieved in mono-cropping of soybean, the highest one in other stages was related to groundnut mono-cropping. In intercropping patterns, oat in oat-groundnut obtained the highest dry matter in all stages. The highest value of protein percentage and organic matter in heading stage, grain filling stage, and grain dough stage was achieved in groundnut in oat-groundnut intercropping. Furthermore, the maximum value of protein percentage and organic matter in booting stage and ripening stage was related to soybean in oat-soybean intercropping. The results of this study clearly indicate that intercropping oat and groundnut affects the growth rate of the individual species in mixtures as well as the dry matter yield and nitrogen accumulation. This information can help in the adaptation of oat- intercrops for increased forage production in new cropping systems.</p>

Plantings of D. uncinatum and P. atropuvpureus were made in October and December 1965 and February and April 1966, and subsequently the plots were either rotationally grazed by sheep, cut with a mower at 3 inches, or left undefoliated. Monthly samples were taken to determine individual plant dry weight, nodule weight per plant, nodule number, and mean weight per nodule. Three samples for plot dry matter yield were also taken. Individual plant dry weight was higher in the October and December sowings, although by the end of the second growing season dry matter yield per plot was higher in the December and February sowings. Dry matter yield of legume was depressed by April planting. D. uncinatum began regrowth in spring 2 months earlier than P, atropurpureus, when minimum temperatures exceeded 48-50�F compared with 57' for P. atropurpureus. Both species had marked seasonal peaks in nodule and plant dry weight. The rapid decline in nodule weight could not be directly related to the onset of flowering or frosts. Grazing caused a greater reduction than cutting in terms of plant and nodule weight and legume yield. In P. atropurpureus nodule weight per plant was reduced through a decline in mean weight per nodule, while in D. uncinatum grazing and cutting reduced nodule number per plant.
