SummaryField investigations conducted at Ludhiana (India) showed that the foliar application of 2-chloroethyltrimethyl-ammonium chloride (CCC) (50% a.i.) at 300,600 and 900 ml/ha about 5 weeks after planting did not depress plant height. The dose of 600 ml CCC/ha was most effective and increased seed yield by 1·31 and 0·74 t/ha over the control (water spray) in 1978–9 and 1979–80, respectively. The corresponding increases in total yield were 1·37 and 0·86 t/ha. However, in 1980–1 when CCC was applied 3 weeks after planting even the lower dose of 300 ml/ha depressed the plant height. Then the treatment of CCC increased significantly the number of tubers of seed size and seed yield by decreasing the ‘ware’ yield but did not influence the total yield. The yields of potatoes were not affected signifioantly by the application of N-dimethyl amino succinamic acid (B 9) and succinic acid (SA).In an experiment where the interaction of nitrogen and CCC was studied both factors not only increased the seed yield but also increased the total yield. However, there was no interaction between nitrogen and CCC.

<div><p><em>The present study was performed to assess the effect of foliar application of water soluble fertilizers on growth and seed yield of cabbage cv. Golden Acre. Four WSF (Multi-K, NP<sub>2</sub>O<sub>5</sub>K<sub>2</sub>O, NP<sub>2</sub>O<sub>5</sub>K<sub>2</sub>O and NP<sub>2</sub>O<sub>5</sub>K<sub>2</sub>O) were tested against control (water). Plant height, no. of branches, pods as well as seed yield was found to increase with the applications of WSFs. Data also revealed that maximum plant height (162.13cm), no. of branches (27.21/plant), no. of pods (1460.49/plant) and seed yield (10.37q/h) were recorded with the foliar application of NP<sub>2</sub>O<sub>5</sub>K<sub>2</sub>O (15-15-30) against the minimum plant height (146.03cm), no. of branches (21.73/plant), no. of pods (915.46/plant) and seed yield (5.50q/h) in untreated plots.  The same treatment i.e. NP<sub>2</sub>O<sub>5</sub>K<sub>2</sub>O (15-15-30) also recorded highest net return (Rs. 3.1lakh/h) as well as cost benefit ratio (1:4.78), and therefore may be recommended for seed production of cabbage.<strong></strong></em></p></div>

Field experiments were conducted to study the influence of foliar nutrition on pod setting percentage, yield and economics of red gram (Cajanus cajan (L.)  under the irrigated condition at Regional Research Station, Tamil Nadu Agricultural University, Paiyur - 635 112, Tamil Nadu, India in Kharif season of 2016-17. To study the effect of different nutrient sources the following treatments were imposed. The treatments include the foliar application of 2% DAP twice at flowering and 15 days thereafter first spray (T1), Foliar application of TNAU pulse wonder at 5 kg/ha at peak flowering (T2), Foliar application of 0.5% MAP twice at flowering and 15 days thereafter first spray (T3). Foliar application of CCC 200 ppm twice at flowering and 15 days thereafter (T4) and Control (water spray)(T5). Among the treatments, it was concluded that application of 0.5% mono ammonium phosphate (MAP) at flowering and 15 days after the first spray recorded the higher grain and stalk yield of 1522 and 6222 kg ha-1 in red gram respectively and also recorded a higher gross income of Rs. 91320, net income of Rs. 50520 and B: C ratio of 2.2. Further, the yield increase was 25% higher yield over control (water spray) and 12% higher over-application of CCC 200 ppm twice at flowering and 15 days after the first spray.

The comparative effect of 0, 0.2, 0.4, 0.6 and 0.8% Zn levels of zinc chelate (Zn-EDTA; 8% Zn) and zinc sulfate (23% Zn) applied as foliar sprays for assuaging zinc deficiency of chickpea cv. Gökçe was evaluated under field condition. The sprays were applied on the plants before blooming stage during 2012 and 2013 growing seasons and seed yield, yield components like plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and mineral concentrations (nitrogen, phosphorus, zinc and iron) in seeds were investigated. Plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and seed yield were investigated. The results showed that increased zinc doses caused an increase in Zn content of seed, while seed yield was not affected similarly. In general, plant height, pod number and seed number per plant increased by the application of zinc. Lower dose of Zn-EDTA and higher dose of ZnSO<sub>4</sub> gave higher yield components. Seed weight, harvest index and seed yield were not significantly influenced by Zn sources and doses; however, mineral concentration of seeds enhanced when Zn doses were increased. It was concluded that foliar application of zinc resulted in an increase in seed mineral contents rather than seed yield of chickpea. The dose of 0.6% with Zn-EDTA was the optimum combination for Zn enrichment in seed of chickpea.

Foliar Fertilizer

Foliar application of fertilizers can guarantee nutrient availability to beans, leading to higher yield and seed quality. Different approaches including glycine have been used to improve mineral nutrient status of plants toward safer products and improved human health. However, limited research has been undertaken to understand the response of beans to amino Zn and Mg foliar fertilizer application in Ghana. This study was conducted to investigate the effect of zinc, magnesium, and combined zinc and magnesium foliar fertilizer application on two improved common bean (Phaseolus vulgaris L.) varieties locally referred to as Adoye and Nsroma in the forest (Fumesua) and forest-savannah transition (Akumadan) agro-ecological zones of Ghana during the 2018 and 2019 cropping seasons. The treatments were arranged in split-plot design with the two improved common bean varieties as the main plot, and foliar fertilizer options (zinc, 200 g/ha; magnesium, 224 g/ha; combined zinc and magnesium, 100 g/ha Zn and 112 g/ha Mg) and water spray (control) as the subplot treatments. The zinc and combined zinc and magnesium treatments had similar and significantly ( P ≤ 0.05 ) higher plant height of 37.1 cm and 38.7 cm compared to the control and magnesium treatments. The results also showed that chlorophyll content was approximately 15.6% higher in plants treated with zinc plus magnesium compared to the other treatments. Similarly, stomatal conductance was significantly ( P ≤ 0.05 ) increased by 35.6% with zinc plus magnesium treatment relative to the other treatments. The improved chlorophyll content and stomatal conductance in those treatments resulted in ∼55.3–80.6% increase in crop biomass and seed yield. Crop performance parameters such as plant height, canopy spread, and chlorophyll content were significantly higher ( P ≤ 0.05 ) at Akumadan, resulting in a greater seed yield of 1486.2 kg/ha compared to 1365.3 kg/ha at Fumesua. Combined application of zinc and magnesium appears to be a potential soil improvement strategy for common bean production in tropical soil environment of Ghana.

Pyracantha coccinea `Lalandei' and `Kasan' were treated with a foliar application of 25, 50 or 100 mg/l uniconazole, 3000 mg/l chlormequat, a soil drench of 0.25, 0.50 or 1.00 mg/container of uniconazole, or 30 mg/container chlormequat. Heights of plants receiving foliar applications of uniconazole were significantly lower than untreated plants in both cultivars. Uniconazole soil drenches also reduced plant height in both cultivars, but differences were not apparent until 8 weeks after treatment. Chlormequat treatments had little effect on plant growth. At harvest, stem dry weight was significantly lower in both cultivars with uniconazole soil drenches and in `Lalandei' treated with 50 and 100 mg/1 and in `Kasan' treated with 100 mg/1 as a foliar application. There was also a tendency for leaf area to increase with uniconazole foliar applications.

The effects of seeding date and seeding rate on the agronomic characteristics of five genotypes of Brassica napus L. were studied for 2 yr at two locations in western Canada. Delayed seeding resulted in a significant increase in vegetative and total yield but a significant decrease in seed yield, harvest index, plant density, racemes per plant and racemes per unit area. Seeding date had no significant effect on seed yield per plant, 1000-seed weight and plant height. Increased seeding rate resulted in a significant increase in plant density, and racemes per unit area, but a significant decrease in harvest index, racemes per plant, seed yield per plant and plant height. Seeding rate had no significant effect on seed, vegetative or total yield and 1000-seed weight. There were significant differences due to genotypes for all variables except for total yield and racemes per unit area.

Paclobutrazol (PBZ), a well-known growth retardant of the triazole family, is mostly used for controlling plant size and growth, resulting in more desirable compact plants for floricultural purposes; however, limited experimental data are available for use of PBZ in field sunflower. The objective of this study was to evaluate the effect of repeated foliar applications of PBZ at rates of 50 + 50 g ha-1(double application) and 50 + 50 + 50 g ha-1 (triple application) on sunflower morphology and productivity. PBZ applications corresponded to growth stages of four to five, five to six, and six to eight true leaves of sunflower plants, respectively. The double foliar application of PBZ reduced sunflower plant height at maturity by 4.4% (or by 11.7 cm). The triple foliar application of PBZ reduced sunflower plant height at maturity by 14.4% (or by 49.2 cm). However, PBZ either in the double or the triple application reduced achene yield per plant by 25.6% and 22.5% and the 100-achene weight by 11.4% and 25.0%, respectively, compared with the non-treated control. Overall, the repeated foliar applications of PBZ at the rates tested in this study, apart from providing a reduction of sunflower plant height, had major adverse effects on achene yield and weight. Thus, different application schemes of PBZ or perhaps different growth regulators should be investigated to control plant height in sunflower.

An experiment was conducted at Regional Agricultural Research Station, Jashore, Bangladesh during rabi season of (2019-2020) to evaluate the effect of foliar application of urea on growth and yield of short durative lentil variety (BARI Masur-9). The experiment was conducted in split plot design with three replications where time of urea spraying, P1= at branching stage, P2= at pod initiation stage were distributed in main plots and doses of urea spraying T1= application of 100% recommended fertilizers as basal except urea, T2= application of 100% recommended fertilizers as basal, T3= application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying, T4= application of 25% of urea with 100% of other fertilizers as basal and rest of the 75% of urea by spraying, T5= application of 50% of urea with 100% of other fertilizers as basal and rest of the 50% of urea by spraying were distributed in sub plots. The highest plant height, number of pods per plant were obtained from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea spraying at pod initiation stage. The highest seed yield was also found from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea spraying at pod initiation stage followed by application of 100% recommended fertilizers as basal and application of 50% of urea with 100% of other fertilizers as basal and rest of the 50% of urea by spraying at branching stage. Plant height, pods per plant and days to maturity showed positive correlation with seed yield. On the other hand days to flower and plants per m2 has no linear relationship with seed yield. The highest marginal benefit cost ratio (3.29) was recorded from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying at pod initiation stage. So based on findings to increase the yield potential of BARI Masur-9 foliar application of urea may be a tool and hence application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying at pod initiation stage may be consider as the best treatment.
