“…Also, potatoes are an important crop in the Central Asian Republics (Loebenstein and Manadilova, 2003). They are the second most important crop in Kazakhstan, after wheat, grown on about 205.000 ha and its yields average 19.5 t ha -1 (Alimkhanov et al, 2021). Potato adapts to many environmental conditions and is of short life cycle when compared with other tropical tuber crops (Horton, 1988, Esan et al, 2021.…”

In this study, field experiment was conducted to assess the effect of different organic fertilizer and mineral fertilizer on mineral and different organic fertilizer treatments effect on available N, P, K contents, the yield of potato (Solanum tubevosum L.), cultivar Astana, nitrate contents of tuber under dark chestnut soil conditions in southeast of Kazakhstan during the spring and summer of 2022. The experiment was carried out in the field and laid out as complete randomized block design with four replicates. Thirteen treatments that are, control without fertilizer treatment, mineral fertilizer with recommended dose (N150P90K120) and eleven different organic fertilizers treatment were used. The results showed that available nutrient (N, P and K) contents of the post-harvest soil were affected by mineral and different organic fertilizers compared to the control. And, the available N, P and K contents in the soils taken from the biohumus (10 t ha-1) and cattle manure (40 t ha-1) treated plots were found to be higher than all of the other treatments and control. Similarly, plots treated recommended mineral fertilizer and different organic fertilizers had a significantly higher yield of potato tuber compared with control. When all applications were compared with each other, it was determined that the treatments that increased the potato yield the highest was the treatment of Biohumus (10 t ha-1) + BioZZ (5 L ha-1, 3 times). The highest nitrate content of tubers was obtained in mineral fertilizer with recommended dose (N150P90K120). Hence, these results suggest that organic production of potato (Biohumus, 10 t ha-1 + BioZZ 5 L ha-1, 3 times) could be an alternative to conventional production in Kazakhstan without reduction in yield, and with low nitrate content of tuber and high available nutrient contents in soil.

This study investigates the impact of phosphorus fertilization on the yield and quality of various alfalfa (Medicago sativa L.) varieties grown in light chestnut soils. Conducted over a three-year period from 2013 to 2015, the research was carried out in the Karasay district of the Almaty region under irrigated conditions. The experiment included six alfalfa varieties: NS Alfa, VS Banat, Mediana, Nera, Niagara, and Kokoray. Four phosphorus treatments were applied: control (no phosphorus), 60 kg/ha (P60), 90 kg/ha (P90), and 120 kg/ha (P120), using double superphosphate as the phosphorus source. The results demonstrated that phosphorus fertilization significantly enhanced both the yield and quality of alfalfa. Across all varieties, the highest yield was observed with the application of 120 kg/ha phosphorus. For instance, NS Alfa's yield increased from 283.3 c/ha in the control to 349.7 c/ha with P120, reflecting a 23% increase. Similarly, VS Banat and Mediana exhibited yield increases of 23% and 25%, respectively, at the highest phosphorus level. The study also revealed improvements in the nutritional quality of alfalfa hay. Crude protein content increased from 20.3% to 22.0% in NS Alfa, while digestible protein content rose from 11.20% to 12.40%. Other quality parameters, including fat and carotene content, also improved significantly with higher phosphorus levels. Moreover, the availability of nitrate nitrogen and mobile phosphorus in the soil increased progressively with higher phosphorus application rates, contributing to better nutrient uptake and overall plant health. This research underscores the importance of phosphorus fertilization in maximizing alfalfa yield and quality. The findings suggest that the optimal phosphorus application rate for enhancing alfalfa production in light chestnut soils is 120 kg/ha, providing valuable insights for sustainable agricultural practices in similar agro-ecological zones.

Article InfoThe amount of yield and adaptation of a cultivar to a new environment is strongly related to nutrient uptake ability. This study was carried out during 2019, 2020 and 2021 seasons to investigate the effect of different forms of chemical compose 20.20.20 fertilization alone or incombination with other fertilizers on morphological plant parameters (number of leaves per shoot, stem length and stem thickness) and leaf nutrient contents (N, P, K and Mg) of young Frantoio olive tree grown in Turkestan region, South Kazakhstan. The study was conducted on 1 years old olive trees of Frantoio in sierozem, under surface drip irrigation, system and uniform in shape and received the common horticultural practices. It was determined that fertilizer treatments significantly influenced number of morphological plant parameters and leaf plant nutrients compared to control treatments at all seasons. Results revealed that all fertilizers as well as the combination between 20.20.20 and Biohumus treatment and/or Nitroammophos treatment significantly increased morphological plant parameters and nutrient contents of young Frantoio olive trees. It can be concluded that the variation in the nutrient uptake ability may be used as a criterion for adaptation of a variety to a new ecological environment.
