The shortage of cassava stem cuttings presents a significant constraint to cassava production in Kilosa district, Tanzania. To address this issue, a field experiment was conducted within the research plots of TARI Ilonga, Kilosa, to evaluate the impact of fertilizer application, planting density, and variety on cassava stem cutting yield. Employing a split-split plot design in a randomized complete block design (RCBD), the experiment featured variety, planting density, and rates of fertilizer combinations as main, sub, and sub-sub factors, respectively. The study focused on three improved varieties of cassava (Kiroba, Chereko, and Mkuranga 1), with planting densities of 10,000, 13,000, and 20,000 plants per hectare, and ten fertilizer treatment rates. Data collected encompassed soil physico-chemical characteristics of the site, total plant height, stem height, stem diameter, number of stem cuttings, and nodes per stem cutting. Analysis of the plant data involved variance analysis, with significant treatments distinguished using Tukey’s honesty significance test (p<0.05). Notably, the application of 150 kg N ha-1 resulted in statistically higher total plant height and stem height, while a planting density of 20,000 plants ha-1 combined with the Kiroba variety exhibited statistically higher numbers of stem cuttings ha-1. The study concludes that for effective stem multiplication, a planting density of 20,000 plants ha-1 and the application of N fertilizers at a rate of 150 kg N ha-1 are recommended.

“…Cassava, the most important tuber crop of the tropics is climate resilient and with its high bioconversion efficiency fosters food and nutritional security in many countries. The production of cassava globally and in India is 311.5 mt and 4.98 mt respectively (Radhakrishnan et al, 2022). While, in Kerala, the production of cassava is 259.26 t (FIB, 2022).…”

A field experiment was undertaken at College of Agriculture, Vellayani during June to December 2019, to assess the efficacy of liquid consortium biofertilizer, Plant Growth Promoting Rhizobacteria (PGPR) Mix - I in cassava and to examine the changes in soil chemical and biological properties with the application. The treatment combinations included four levels of biofertilizer [PGPR Mix - I liquid (L) @ 2 %, PGPR Mix - I liquid (L) @ 5 %, PGPR Mix - I powder (P) formulation @ 10g of 2 % mixture per plant, without biofertilizer] and three levels of nutrients, with 50: 50: 100 kg NPK/ha as the standard dose of nutrients (SDN), [50 % SDN, 75 % SDN, 100 % SDN]. The 4 × 3 factorial experiment was laid out in randomized block design with three replications. The results of the study revealed that the liquid biofertilizer consortium at 5 per cent + 75 percent SDN (37.5: 37.5: 75 kg NPK /ha) recorded significantly superior yield attributes in cassava and improved the soil organic C, available K status and microbial count.

“…Organic farming aims at sustainable food production, by minimising the negative impacts of water and nutrient depletion, soil degradation, and loss of biodiversity (Dobrovolska & Espejo, 2018;Seena Radhakrishnan et al, 2022). In Ukraine organic production is regulated by the law of Ukraine 'On general principles and standards of organic production, circulation and labelling of organic product' No.…”

The development of organic agriculture is a long-term global trend; with different local factors that affect the development rate. Ukraine is one of the largest food suppliers in the world and this also applies to organic production. The evaluation of organic production at Skvyra Organic Research Station was conducted in 2015-2020 on 40 ha land; focusing on the economic performance of the enterprise and the specialization of production. The systematic approach and dialectical method of cognition were used to identify the key factors in the development of organic farming. The purpose of the study is an organizational and economic analysis of a state enterprise that is making a gradual transition from intensive to organic production, in order to determine the main principles that stimulate the development of organic production, and to overcome the challenges faced by the enterprise on the way to the introduction of organic production. The results indicate that the enterprise is profitable but does not operate up to its potential. The key issues were identified in the lack of focus on marketable crops, efficiency of labour, crop production, and management. The enterprise is negatively affected by the current legal framework and insufficient financial stability. The enterprises income consists of selling crops (i.e. cereals, legumes) and service-to-business (i.e. laboratory testing), with no state funding. Further results show the relation of the production and specialization with climatic, natural, biological and socio-economic factors. To improve the organisational and economic framework for the development of organic production, Ukrainian enterprises should focus on cost-effective products. Furthermore, competition between agricultural enterprises should support deeper specialization and production of competitive products, contributing to the profitability and economic stability of producers
