  Increasing economic yield was a consequence of a high net photosynthetic rate in the later growth stage of sweet potato (Xie et al., ). In addition, sweet potato is a C3 crop with C3 photosynthetic assimilation that is more able to acclimate to shade than crops with C4 assimilation (Sage and Mckown, ). These results support the third Cited by: 1.   Interest in fresh vegetables is on the increase due to their protective effects against several diseases. Listeria monocytogenes is a human pathogen easily found in vegetables. The purpose of this review article is to analyse the influence of the agricultural practices applied in pre-harvest, the environmental biotic and abiotic factors characterising the cultivation field, as well as the Cited by: effect of various agronomic practices on potato crop in agra region of uttar pradesh Article (PDF Available) April with Reads How we measure 'reads'. yield and quality, is an effective means to build assets and increase livestock productivity. The purpose of this paper is to assess briefly the role of crop residues among feed resources and to summarise the crop management factors that affect the yield and quality of crop residues. 2. Crop residues Importance of crop residues among feed.

Location was significantly influence all parameters except yield. However the highest potato yield was obtained at 70cm: 30cm ( ton ha-1), kg ha-1 DAP and kg ha-1 urea ( ton ha -1) and at Mechara ( ton ha -1). At Mechara the highest (11 ton ha -1) potato yield was recorded at 70cm: 30cm spacing and kg ha-1 of DAP and kg.   Many of the opportunities to influence a potato crop occur prior to planting as there is limited opportunity during growth to influence key crop parameters; so, effective planning is vital to ensure that these are not compromised. Inputs and interventions to the growing crop then enable the potential of the planned crop to be achieved. the sweet potato crops are grown on poor or marginal land with little attention to proper agronomic practices. Most fertilizer studies have been devoted to rates of fertilizer applied. The purpose of this work is to evaluate the major nutrient requirements (N-P-K) of the sweet potato . The duration of crop growth and the interception of solar radiation are the two components of equation (1) that have contributed most to increased biomass and total photosynthesis of crops and thereby yield. Conventional breeding and genetic manipulation and agronomic practices .

Appropriate plant establishment techniques are essential for successful crop growth and yield. Cutting characteristics are important factors that may affect yield and yield components. The effects of cultivar (Kudadie, Bareda and Awasa), planting position (horizontal and vertical), type of planting material (terminal vine cuttings with and without leaves) and cutting length (20, 25 and study c learly showe d that yield and yield componen ts of sweet potato at Delbo watershed can be enhanced by combining FYM and inorg anic fertilizers. In this study the highest yield ( 12t/ha. A field study was initiated to generate information on dry matter yield and some biometric parameter effects on yield of seven sweet potato genotypes in weathered ultisols in the humid tropics. The experiment, which was laid out in a randomize complete block design with four replications was conducted at National Root Crops Research Institute, Umudike, Abia State, Nigeria (05°29'N, 07°32'E. The adaptive responses of different sweet potato cultivars to different agro-ecological areas may vary, and sweet potato is an important crop for small-holder farmers in KwaZulu-Natal (KZN) of South Africa, which has diverse agro-ecological areas. Adaptive responses of sweet potato cultivars in KZN’s ecological regions are not known.
