Adoption of Recommended Varieties: A Farm-level Analysis of Wheat Growers in Irrigated Punjab

This study uses farm level data to analyse the determinants of adoption of recommended wheat varieties in irrigated Punjab, Pakistan. A notable proportion of wheat acreage is sown to non-recommended wheat varieties in the province. These cultivars had either lost (overtime) or did not have resistance against yellow rust. Farm size, education, and size of wheat enterprise on the farm are the important determinants of adoption of recommended wheat varieties while tractor ownership and irrigation source play a positive but insignificant role in the adoption decisions. Age and tenure proved to be less of a constraint towards adoption of the recommended wheat varieties. The likelihood of the adoption of recommended wheat varieties varied among tehsils, with the highest probabilities of adoption in Melsi and Arifwala tehsils of cotton-wheat zones I and II respectively.

Some Non-price Explanatory Variables in Fertiliser Demand: The Case of Irrigated Pakistan

It follows from the experience of World economies that rising and balanced use of fertilisers is the key factor in agricultural productivity [FAO (1995); SFS and STI (1996); Habib-ur-Rehman (1982) and Pinstrup-Anderson (1976)]. In the case of Pakistan the stepped up fertiliser use has been argued to be incritable to realise existing untapped yield potential of major crops [Johnston and Kilby (1975)] and to induce yield increasing technological change in future [John Mellor Associates and Asianics Agro-Dev. International (1993)]. Although proper malnutrition involves the use of primary, secondary and micro-nutrients, Nitrogen (N), Phosphorus and Potassium (K) or NPK is generally considered to be sufficient to harvest normal crop yields [FAO and IFA (1999)]. Given this situation, this paper looks at various factors that determine fertiliser use in Pakistan. Although price of fertiliser is a critical factor in this respect [Schultz (1965) and Johnston and Cownie (1969)], only non-price factors are considered in this paper due to limitations of data. Apart from this introductory section, the paper comprises of three more sections. The following Section 2 explains the data and the empirical model. Section 3 presents the results. Section 4 summarises the main findings along with their policy implications.

Growth of Livestock Production in Pakistan: An Analysis

Agriculture is the backbone and single largest sector of Pakistan’s economy as its contribution to Gross Domestic Product (GDP) exceeded 25.3 percent during 1997-98. Crops, livestock, fishing and forestry sub-sectors being its main components, only crop and livestock sub-sectors are of critical importance. They accounted for 59.6 and 36.2 percent of the sector’s output respectively. Because of the ongoing process of structural transformation, agriculture’s share in the national economy is shrinking. From 39 percent of GDP in 1969-70 it has fallen to its current levels [Pakistan (1999a)]. The livestock sub-sector however has not followed suit. It has risen from 27.3 percent in 1969-70 to 36.2 percent in 1997-98. This trend in fact would be more pronounced if the national accounts did not underestimate the sub-sector’s components such as farm yard manure, dung cakes for household fuels and animal draft power. Apart from its contributions to national income, the livestock sub-sector is an active employer of thousands of landless poor and subsistence and semi-subsistence small farming families. Being a household activity, women are a special beneficiary of employment in the sub-sector. It is a major source of nourishment like milk, butter oil, eggs and meat and adds immensely to the health, nutrition and well being of rural as well as urban people. While animal fat and butter oil supplies are helpful in containing vegetable oil imports, many products of livestock origin such as wool and wool products, leather and leather made-ups and animal casings are exported and contribute significantly to hard earned foreign exchange [Ahmad, Ahmad and Chaudhry (1996)]. It follows from the above that the livestock sub-sector is likely to maintain its position as the dominant sub-sector of Pakistan’s agricultural sector or even that of the national economy for quite sometime in the future. Despite the rising and critical importance of the sub-sector, there, however, is no corresponding emphasis on analysing its achievements, problems and future prospects and likely policies to brighten these up. In view of this limitation, the present paper makes a limited attempt to study the growth process of the livestock sub-sector.

Determinants of Higher Wheat Productivity in Irrigated Pakistan

While agriculture plays a vital role in overall performance of the economy of Pakistan, its crop sub-sector contributes the major portion to total value added in the sector. Wheat constitutes the most important crop that contributed 12.1 percent towards value added in agriculture and accounted for 37.18 percent of the total cropped area in the country during 1999-2000 [Pakistan (2001)]. The performance of wheat crop affects the overall growth rate, import bill, and nutritional standard of our people especially, the urban poor. It occupies a pivotal position for attaining national food-security goals. Wheat management in complex farming systems is influenced by time conflicts in the harvesting of preceding crops and the sowing of wheat, and interactions due to residual effects on succeeding crops [Byerlee, et al. (1986]. Conventionally, less dynamism is found in wheat management practices, especially when it is grown after cash crops like cotton, rice and sugarcane. The rabi 1999-2000 was an exceptional season for wheat as rice, cotton, and sugarcane crops succumbed to market forces which ultimately resulted into heavy economic losses to the farming community. Timely announcement of a quantum increase in the support price of wheat is assumed to induce the farmers to deviate from usual wheat management practices for better production. The payback to the presumed transition in conventional wheat production practices was unprecedented

PRAKTIK KARTEL MASKAPAI PENERBANGAN DI ERA REVOLUSI INDUSTRI 4.0

Industrial Revolution 4.0 is a new breakthrough in the business world by relying on information and communication technology. The impact of this industrial revolution also occurred in Indonesia. In the aviation industry for example, ticket booking can be directly purchased via mobile phone. The rapid growth of the national aviation industry makes competition between airlines occur ranging from services to ticket prices. This research uses normative research methods, namely using legislation approaches and conceptual approaches on the concept of conspiracy and cartels by analyzing potential cartels against rising airfares. Business competition methods if done healthily will benefit both consumers and businesses / producers, but unfair business competition can give birth to monopolies and cartel practices. Cartels are considered criminal acts accompanied by criminal fines and/or confinement. The Business Competition Supervisory Commission responded to these allegations by conducting an investigation that was previously only within the limits of research, in the process of investigation must look for at least two tools of evidence to advance to the filing stage then proceed to court
