The population of Ukraine should receive fresh greens from early spring to autumn from open field production and the period of growing spinach will ensure the supply of fresh greens. The purpose of the research was to study the possibility of extending the period of fresh greens supplying from the open field due to the extension of the seed sowing period in the open field. The research was conducted in 2019-2021 in the conditions of the Southern Steppe of Ukraine. For the research, field, statistical, calculationanalytical and laboratory methods were used. The varieties Fantaziia and Malakhit were studied. The behaviour of plants after six sowing dates was examined. The control variant was the variety Fantaziia for sowing in the 1st decade of April. It was found that plants of both varieties of spinach had a larger leaf surface (114.2-127.7 cm2 ) in the early sowing period. Plants which were sown in August had a smaller leaf surface – 86.0-106.2 cm2 . The highest yield of marketable green mass was obtained for sowing in the 3rd decade of April and 2nd decade of May. The variety Fantasia provided 22.9-23.0 t/ha, and the variety Malakhit provided 23.3-23.9 t/ha. The sowing date had a significant influence on the main chemical parameters of spinach of the Fantaziia and Malakhit varieties. The higher indicators were the sowing dates in the third decade of April and the second decade of May, when the brix reached the level of 6.4-6.8%, the sugars content – 2.3-2.4% and the content of vitamin C – 58-70 mg/100 g. It was established that the soil and climatic conditions of the Southern Steppe of Ukraine were suitable for sowing spinach in six dates and would ensure an uninterrupted supply of products from the 3rd decade of April to the end of September inclusive, and in years with favourable weather conditions in the 2nd to 3rd decades September to mid-October. Such approach will solve the problem of seasonality in the consumption of fresh vegetables. The sowing dates are recommended to agricultural producers of spinach in order to extend the period of receiving fresh greens from the 3rd decade of April to the end of September and in some years to the middle of October

Purpose: Cauliflower (Brassica oleracea var. botrytis L.) requires large amounts of nitrogen (N) fertilizer to produce high yields. This study was carried out for the aim of determine the effect of plant growth promoting rhizobacteria (PGPR) (Paenibacillus polymyxa RC14, Bacillus subtilis RC63 and Pseudomonas fluorescens RC77), organic chicken manure (OCM) (4000 kg/da), 3 levels of mineral fertilizer [(NPK1 (80 kg/ha N+50 kg/ha P+80 kg/ha K), NPK2 (160 kg/ha N+75 kg/ha P+160 kg/ha K) and NPK3 (200 kg/ha N+100 kg/ha P+200 kg/ha K)] and combination of these applications on growth, yield and quality of cauliflower under field conditions. Materials and Methods: Field experiments were conducted in randomized complete block design with four replications. Treatments were 1. Control (No Fertilizer Application; 0 kg /ha NPK), 2. NPK1 (80-50-80 kg / ha NPK), 3. NPK2 (160-75-160 kg /ha NPK), 4. NPK3 (200-100-200 kg /ha NPK), 5. PGPR, 6. Organic Chicken Manure (OCM), 7. PGPR + OCM, 8. NPK1+PGPR, 9. NPK2+PGPR, 10. NPK3+PGPR, 11. NPK1+ OCM, 12. NPK2+ OCM, 13. NPK3+ OCM, 14. NPK1+PGPR+ OCM, 15. NPK2+PGPR+ OCM, 16. NPK3+PGPR+ OCM Results: The highest curd weight and marketable yield were observed in NPK2+ OCM in 2014 while in NPK1+PGPR+OCM and NPK2+PGPR+OCM in 2015. NPK2+ OCM elevated the curd weight and marketable yield by 300% compared to the control in 2014. NPK1+PGPR+OCM increased the curd weight and marketable yield by 200% compared to the control in 2015. The highest TSS was observed in the control in 2014 whereas NPK1+PGPR+OCM gave the highest value. NPK treatments elevated the NO3 content of cauliflower curds. In 2014 the highest ascorbic acid content was determined in PGPR while the control gave the highest content in 2015. The highest oxalic acid contents were observed in NPK treatments. Furthermore, PGPR and OCM treatments generally reduced the oxalic acid contents of the cauliflower. Conclusion: NPK with OCM and PGPR applications could be advisable for yield and quality parameters of cauliflower. Furthermore, PGPRxOPM combination was advisable for efficiently using in organic agricultural producing.Purpose: This study was carried out for the aim of determine the influence of plant growth promoting rhizobacteria (PGPR) (Paenibacillus polymyxa RC14, Bacillus subtilis RC63 and Pseudomonas fluorescens RC77), organic chicken manure (OCM) (4000 kg/da), 3 levels of mineral fertilizer [(NPK1 (80 kg/ha N+50 kg/ha P+80 kg/ha K), NPK2 (160 kg/ha N+75 kg/ha P+160 kg/ha K) and NPK3 (200 kg/ha N+100 kg/ha P+200 kg/ha K)] and combination of these applications on growth, yield and quality of cauliflower under field conditions.

“…[2] Thus, it is called as "Mines of Minerals" [2]. "Spinach is very sensitive to N fertilization and it is one of the highest nitrate (NO3) accumulator's" [3,4,5]. "With an intention to increase the yield of greens, farmers are tempted to apply higher quantities of nitrogenous fertilizers, which may lead to accumulation of anti-nutrient factors in the greens beyond permissible limit" [6].…”

Integrated nutrient management system is an alternative system for the sustainable and cost-effective management of soil fertility by combined apply of inorganic with organic materials resulting in rising soil fertility and productivity without affecting environment. Keeping in this view the present investigation was carried out at Polyhouse of Dr. B.R. Ambedkar university of social science Mhow, Indore (M.P.) during 2022 to study “The impact of integrated nutrient management on growth and yield of Palak (Indian Spinach)”. Experiment was laid out in randomized complete block design with 4 replications. The experiment comprised of 6 treatments i.e. T1 (75% RDF through inorganic fertilizers + 25% RDF through VC), T2 (75% RDF + 25% RDF through FYM), T3 (50% RDF + 50% RDF through VC), T4 (50% RDF + 50% RDF through FYM), T5 (100% RDF only inorganic), T6 (Control or without any fertilizers). All observations were recorded at 30, 45 and 60 days after sowing (DAS). The results shows that the highest value of plant heigh (20.16, 29.77 and 44.69 cm), number of leaves plant-1 (12.07, 21.57 and 37.82), leaf width (4.83, 4.91 and 8.58 cm), leaf length (9.48, 22.10 and 23.24 cm), length of petiole (6.56, 9.27 and 10.89 cm), dry and fresh weight (4.49, 9.32 and 19.59 g) were recorded with the application of T5 (100% RDF) which was significant over T1 (75% RDF + 25% RDF through VC) and T2 (75% RDF + 25% RDF through FYM) and at par with T3 (50% RDF + 50% RDF through VC) at 30, 45 and 60 DAS. Similarly maximum yield (95.87, 95.48 and 90.20 q ha-1) was recorded with the application of T5 (100% RDF) which was significant over T1 (75% RDF + 25% RDF through VC) and T2 (75% RDF + 25% RDF (FYM) and at par with T3 (50% RDF + 50% RDF Vermicompost). Application of T3 (50% RDF + 50% RDF through VC) was also found significant over T4 (50% RDF + 50% RDF through FYM), T1 (75% RDF + 25% RDF through VC) and T2 (75% RDF + 25% RDF through FYM) with the values of 94.84, 94.00 and 88.77 q ha-1 at 30, 45 and 60 DAS. Among all treatment application of T3 (50% RDF + 50% RDF through VC) gave maximum yield which not only increase yield but also save cost of 50% RDF. Therefore, organic and inorganic fertilization may have a significant positive impact on the growth and yield of Palak.
