Background: Optimum planting date and appropriate fertilizer module are essential facets of chrysanthemum cultivation, to enhance quality yield, and improve soil health. A field-based study was undertaken over multiple growing seasons in 2022 and 2023, where six different planting dates, viz., P 1 :June 15, P 2 :June 30, P 3 :July 15, P 4 :July 30, P 5 :August 15 and P 6 :August 30 and two fertilizer modules, FM 1 :Jeevamrit @ 30 ml plant -1 and FM 2 :NPK @ 30 g m -2 were systematically examined using a Randomized Block Design (factorial), replicated thrice., Results: P 6 planting resulted in early bud formation (44.03 days) and harvesting stage (90.78 days). Maximum plant height (79.44 cm), plant spread (34.04 cm), cut stem length (68.40 cm), flower diameter (7.83 cm), stem strength (19.38˚), vase life (14.90 days), flowering duration (24.08 days), available soil N (314 kg ha -1 ), available P (37 kg ha -1 ), available K (347 kg ha -1 ), bacterial count (124.87 × 10 7  cfu g -1 soil), actinomycetes count (60.72 × 10 2  cfu g -1 soil), fungal count (30.95 × 10 2  cfu g -1 soil), microbial biomass (48.79 µg g -1 soil), dehydrogenase enzyme (3.64 mg TPF h -1  g -1 soil) and phosphatase enzyme (23.79 mol PNP h -1  g -1 soil) was recorded in P 1 planting. Among the fertilization module, minimum days to bud formation (74.94 days) and days to reach the harvesting stage (120.95 days) were recorded with the application of NPK @30 g m -2 . However, maximum plant height (60.62 cm), plant spread (23.10 cm), number of cut stems m -2 (43.88), cut stem length (51.34 cm), flower diameter (6.92 cm), stem strength (21.24˚), flowering duration (21.75 days), available soil N (317 kg ha -1 ), available P (37 kg ha -1 ) and available K (349 kg ha -1 ) were also recorded with the application of NPK @300 kg ha -1 . Maximum vase life (13.87 days), OC (1.13%), bacterial count (131.65 × 10 7  cfu g -1 soil), actinomycetes count (60.89 × 10 2  cfu g -1 soil), fungal count (31.11 × 10 2  cfu g -1 soil), microbial biomass (51.27 µg g -1 soil), dehydrogenase enzyme (3.77 mg TPF h -1  g -1 soil) and phosphatase enzyme (21.72 mol PNP h -1  g -1 soil) were observed with the application of Jeevamrit @ 30 ml plant -1 ., Conclusion: Early planting (P 1 ) and inorganic fertilization (NPK @ 30 g m -2 ) resulted in improved yield and soil macronutrient content. The soil microbial population and enzymatic activity were improved with the jeevamrit application. This approach highlights the potential for improved yield and soil health in chrysanthemum cultivation, promoting a more eco-friendly and economically viable agricultural model., (© 2024.

Pulses low yield in the arid and semiarid climates are imbalanced use of chemical fertilizers and no use of organic matter (animal and crop residues incorporation). The hypothesis was tested that integrated use of potassium (K) and animal manures could increase mungbean (Vigna radiata L. Wilczek) productivity and profitability in the semiarid climate of Peshawar. A field experiment was carried out to investigate the effect of organic matter (composted animal manures) (5, 10, and 15 t ha−1) and potassium (30, 45, and 60 kg ha−1) under irrigated (three irrigations, no water stress) and dryland or limited irrigated (one irrigation, water stresses before flowering and after pod formation) condition on mungbean (cv. Ramazan 92). The experiment was carried out in the summer of 2017 at Agronomy Research Farm, the results revealed that crop under no water stress had delayed phenological development (took more days to flowering, pod formation, and physiological maturity), better growth by producing taller plants with a more number of leaves, nodules, and pods plant−1, seeds pod−1, heavy 1000-grains weight, higher biological and grain yields than water stress condition. The experiment also confirmed that the combination of the highest rate of K and organic matter had improved the vegetative growth and development, and significantly increased yield and yield contributing parameters under both water stress and no stress conditions. It was concluded that mungbean yield and yield components increased with combined application of 60 kg K ha−1 + 15 t OM ha−1 under full irrigated (no water stress) and limited irrigated (water stress) conditions.

This investigation was done for the assurance of potassium amassing in four assortments of maize (grains, shoot and root), soil, and water and in seven tissues of chickens (kidney, liver, heart, bone, gizzard, breast meat). The analysis of variance showed significant differences for potassium concentration in water in all sources of water; however, the season and variety significantly influenced the quantity of potassium in cereals. The corn varieties MMRI, Sadaf, and Pearl behaved differently when treated with water from various sources. Water taken from sewage had a higher concentration of potassium compared to canal and groundwater that is why the maize plants irrigated with this water had a higher grouping. Data regarding potassium concentration in different body parts of chicken showed that season and treatment have a significant effect on the potassium concentration in chicken organs. The variety was non-significant for the potassium concentration only in the bone. Season × Variety interaction was only significant in blood, meat heart, and gizzard. Season × Treatment and Variety × Treatment interactions were significant in the heart, kidney, and gizzard. The potassium contents were higher in the chicken body parts that were reared on grains irrigated with sewage water as compared to other groups. The potassium contents were higher in the chicken meat (96.23 ± 0.00) reared on grains of the Pearl variety raised with the sewage water. In a nutshell, the irrigation of grains with sewage water led to accumulation of nutrients greater than those irrigated with ground or canal water. [ABSTRACT FROM AUTHOR]

Industrial hemp (Cannabis sativa L.) is a fibrous plant with high biomass production, and can survive under heavy metal stress conditions. To determine the growth potential of industrial hemp on lead (Pb) contaminated soil, a pot experiment was conducted using two varieties Bamahuoma (BM) and Yunma-1 (Y1), under different levels of nitrogen (N) fertilizer viz., 0 (control), 0.1, 0.3, 0.5 and 0.7 g kg−1. The soil was artificially spiked with Pb using PbCl. Lead uptake and its accumulation in different organs of both hemp varieties were analyzed. Increasing level of N fertilizer caused a significant increase in the plant growth and dry biomass production in both varieties, while Y1 showed more tolerance to Pb, than BM. Furthermore, N (%) was higher in the leaves and stems then in the roots. Contrastingly, Pb was highly accumulated in the roots then in the leaves and stems of both varieties under varying levels of N fertilizer in the soil. Lead uptake and its accumulation in different plant parts were increased with the increase in N fertilizer in the soil. Hence, these findings indicate that external N fertilization is a useful strategy to enhance dry biomass and Pb accumulation in industrial hemp. [ABSTRACT FROM AUTHOR]
