Effect of protected structures on yield and horticultural traits of bell pepper (Capsicum annuum L.) in Indian cold arids

Under cold arid Ladakh condition, production of bell pepper is limited by climate and short growing season and people depend upon outside supply for consumption. Keeping this in view, seven promising hybrids popular in other parts of country were tried in six different protected structures. Design of the experiment was split plot. Results revealed that Mud wall greenhouse recorded highest yield per ha and number of...

Dairy production and marketing in Uganda: Current status, constraints and way forward

Dairy production in Uganda is mainly based on low-input traditional pasture production systems. This makes Uganda one of the few countries in the world that are low cost producers of milk. Dairy farming could play a greater role in the economy considering its strong potential to provide rural employment and regular income to the many resource-poor households. However, milk production is still largely subsistence. There...

Effect of resistance and trichome inducers on attraction of Euschistus heros (Hemiptera: Pentatomidae) to soybeans

Seed-sucking stink bugs are notable among the insect species that are economically relevant to Brazilian soybean crops. This study sought to evaluate how the application of resistance inducers affects the attraction of the neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), to soybean plants, which is correlated with trichome density in these plants. Seeds from various soybean varieties, including...

Analyzing the factors affecting the market participation of maize farmers: A case study of small-scale farmers in greater Giyani Local Municipality of the Mopani District, Limpopo Province

The aim of the study was to analyze factors affecting the market participation of small-scale maize farmers in Greater Giyani Municipality. The study hypothesizes that there are no factors affecting market participation in small-scale maize farmers in Greater Giyani. The study used cross-sectional data collected from 92 small-scale maize farmers. The logistic regression model was used to analyze data. The logistic...

Methods of extraction and bioavailability of zinc for the soybean culture fertilized with NPK+Zn

This work aims to evaluate the extractors Mehlich-1 and diethylene triamine pentaacetic acid (DTPA) and their extraction capacity for zinc (Zn) correlating them with the bioavailability of this nutrient in the soybean culture [Glycine max (L.) Merril] cultivated in a Eutrophic Red oxisol, in order to find better correlation between fertilization doses and plant absorption of zinc in conditions of the Parana Western...

Incidence of heart rot at pomegranate fruits caused by Alternaria spp. in Cyprus

During the growing season of 2012, pomegranate growers in Cyprus indicated that they face a troublesome problem causing fruit decays. This study conducted to identify the pathogen causing fruit decays and determine disease incidence in three different pomegranate cultivars in Cyprus. Disease defined as heart rot caused by fungi: Alternaria spp. Incidence of heart rot was determined as 20.31, 14.91 and 9.82% for the...

Application of wavelet transform in the classification of pollen grains

This paper presents a proposal for the automatic classification of pollen grains, to assist in the analysis of the botanical origin of honey samples. For this task, techniques based on computer vision and machine learning were used. At first, the pollen grain image was segmented using a technique based on watershed. Then, a wavelet transform technique was used to extract texture features from the segmented image....

Applied multiple regression for autocorrelated sugarcane data

The major concern with the substitution of fossil fuels is the air pollution which contributes to countries like Brazil to adopt new sources of clean and renewable energy as ethanol from sugarcane. It is extremely important to maximize the production of sugarcane mainly focused on the production of ethanol. This work aimed to establish a model of multiple regression that targets sugarcane traits, which could contribute...

Resistance of grain of maize landrace varieties under breeding in Southern Piauí to attack by Sitophilus zeamais

The objective of this study was to evaluate the resistance of grain of maize landrace varieties to attack by Sitophilus zeamais in new breeding program in Brazil. The experiments were performed in the Zoology and Animal Nutrition Laboratory, Federal University of Piauí/Professor Cinobelina Elvas Campus (UFPI/CPCE) in Brazil, using seed of two maize landrace varieties, one with two origins [purple straw maize from...

Initial development of crambe due to sowing in different depths

The aim of this paper is to evaluate the initial development of crambe due to sowing in different depths. The experiments were carried out in conditions of protected cultivation in two agricultural seasons. It was used as delimitation completely randomized, with five treatments characterized by sowing depth (1, 2, 3, 4 and 5 cm), with five repetitions, totalizing 25 plots per experiment. The experiments were conducted...

Effects of intra-row spacing on plant growth and yield of onion varieties (Allium cepa L.) at Aksum, Northern Ethiopia

Lack of improved varieties and production practices have been the major bottlenecks of onion production and productivity in Tigray, particularly at Aksum area. Since there have been no recommended intra-row spacing, farmers used to practice non-uniform plant spacing. Thus, a field experiment was conducted to investigate the influence of intra-row spacing, variety and their interactions on growth and yield of onion,...
