Onion is one of the most important bulb crop grown all over the India. It belongs to family Alliaceae and locally known as Pyaj. An experiment was conducted to determine the effect of micronutrients on growth of Onion (Allium cepa L.) during Rabi season of 2019-2020 at the Horticultural Research centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). The experiment was laid out in Randomized Block Design (RBD) with three replications. The maximum plant height (27.18, 43.32, 49.22 and 47.45 cm at 30, 60, 90 and at harvest after days of transplanting, respectively), number of leaves (5.11, 8.83, 12.87 and 13.98 at 30, 60, 90 and at harvest after days of transplanting, respectively), diameter of stem per plant (6.64, 8.97, 11.13 and 10.95 mm at 30, 60, 90 and at harvest after days of transplanting, respectively) and length of longest leaf at harvesting (43.56 cm) were reported under treatment T9 -RDF + Zinc Sulphate 20 Kg ha-1 + Borax 10 Kg ha-1 whereas the minimum values for above parameters were recorded under T11- control. Hence application of RDF + Zinc Sulphate 20 Kg ha-1 + Borax 10 Kg ha-1 is worth recommendable for formers to get significantly better growth of Rabi onion.

Onion (Allium cepa L.) is one of the most important vegetables in family Alliaceae, which is cultivated worldwide. In onion, weeds are among one of the major concerns which cause its yield reduction. The present study was designed to assess the effectiveness of different methods for weed control in onion. In this study, five treatments were selected including control, black polythene mulch sheet, white polythene mulch sheet, Dual Gold spray @ 9.0 mL L-1 and Preact spray @ 7.5 mL L-1 to control weeds. The weedicides were applied as pre-emergence sprays before transplanting the seedlings. The experiment was laid out in Randomized Complete Block Design with three replications. From the results, it was concluded that there were significant differences among the studied weed control treatments. Among the five treatments, greater plant height (33.0 cm), number of leaves per plant (8), bulb diameter (4.7 cm) and bulb weight (73 g) were observed in the ridges covered with black mulch sheet. However, the minimum weed biomass (fresh and dry) was recorded in black mulch sheet and Preact pre-emergence weedicide spray (140 and 80 g in both). Thus, black polythene sheet as mulching material was found better option for weed management in onion fields.

The study was conducted at experimantal field at Faculty of Agriculture, Asahan University, Asahan Regency on October 2020 until December 2020. The study aims to the find out the growth response and production of shallots (Allium cepa L.) to the concentration of coconut water and growth media veticulture. This study used randomized complete block design with two factors: (1) Concentration of coconut water (K) with 3 levels: K1 = 25% (250 ml coconut water + 750 ml water), K2 = 50% (500 ml coconut water + 500 ml water), K3 = 75% (750 ml coconut water + 250 ml water) and (2) growth media (M) with 3 levels: M1 = soil + cow manure (1:1), M2 = soil + cow manure (2:1), M3 = soil + cow manure (3:1). Observation parameters were plant height, number of leave, number of bulbs, bulbs weight. The results showed that coconut water concentration had a significant effect on the number of tubers per clump and tuber wet weight, but had no significant effect on observations. plant height and number of leaves, the best treatment at K3 = 75% (750 ml coconut water + 250 ml water). The planting medium did not significantly affect the observations of plant height, number of leaves, number of tubers per clump and wet weight of tubers. The interaction between the concentration of coconut water and growing media did not have a significant effect on all observed variables.

The investigation was undertaken to determine the effect of spacing and cultivars on economic horticultural traits of onion. In trail different spacing was taken 7.5x10cm, 10x10cm, 12.5x10cm and 15x10cm. Three varieties viz. NHRDF Red-3, NHRDF Red-2 and Agrifound Light Red were used for study. The layout of experimental field was laid down in Factorial Randomized Block Design with 3 replications. It is clearly revealed that the significantly widest spacing (15x10cm) produced higher plant height (70.65cm), number of leaves (9.45) and neck diameter (4.48cm) of plant. The bulb length (6.78cm), diameter (7.20 cm) and number of scale per bulb (8.50) also the same trend in widest spacing (15x10cm). The weight of individual bulb of onion (50.56g) was increased with the wider spacing (12.5x10cm). On the contrary, yield ha-1 was the highest (406.45 q ha-1) at closer spacing (10x10cm) and the lowest was (365.50 q ha-1) at wider spacing.

Saline irrigation water is becoming an important water source as fresh water is fast becoming a scarce resource in many areas of the world, including Eswatini, especially in arid and semi-arid regions.  A study to test the response of two varieties of spinach (fordhook giant and mustard) to salinity was conducted in a field pot experiment at the Faculty of Agriculture at the Luyengo Campus of the University of Eswatini.  The treatments were laid in a randomized block design (RCBD).  The experiment consisted of four treatments, each replicated twelve times.  Treatments were salinity levels of 0.0 dS/m, 1.5 dS/m, 2.0 dS/m and 3.5 dS/m.  All the treatments were subjected to similar agronomic practices. Spinach was grown and observed for a period of five weeks.  Plant height was measured and the number of leaves counted weekly throughout the experiment. Significant differences (P < 0.05) between salinity treatments were obtained for plant height beginning in week 2 but were more pronounced in week 3, 4 and week 5.  No significant differences were obtained for the number of leaves.  There were however, clear significant differences between spinach irrigated with none saline irrigation water compared to saline irrigation water.   It was concluded that irrigating spinach with saline water of more than 2.0 dS/m drastically reduce plant growth but not the number of leaves under the conditions of the experiment.
