Studies on the productive performance of jersey x sahiwal cows in Chittoor district of Andhra Pradesh

Season of birth and age at sexual maturity had a non-significant effect on first lactation milk yield. The overall least-squares mean lactation milk yield was 2154.07 ± 16.88 L. Significant effect of batch was found on first lactation milk yield in the present study. Cows belonging to 4th batch recorded significantly (P<0.0) higher lactation milk yield of 2475.93 ± 19.65 L.  The effects of...

Soil pH, electric conductivity and organic matter after three years of consecutive amendment of composted tannery sludge

Experiments were carried out under field conditions to evaluate the effects of composted tannery sludge (CTS) on soil pH, electric conductivity (EC) and soil organic matter (SOM) content after three years of amendment. The CTS was applied at 0, 2.5, 5.0, 10.0 and 20.0 ton ha-1. In each year, soil samples were collected 60 day after CTS amendment. After three years, the CTS increased about 5, 46 and 69% of the soil pH,...

Improving and sustaining soil fertility by use of enriched farmyard manure and inorganic fertilizers for hybrid maize (BH-140) production at West Hararghe zone, Oromia, Eastern Ethiopia

A study was conducted at the Haramaya University Chiro Campus to determine the effect of enriched FYM and inorganic fertilizers on grain yield of maize and soil chemical properties. FYM was used either alone or in combination with inorganic fertilizers as follows: Control (zero fertilizers and FYM), 10 tons/ha FYM, 8 tons/ha FYM and 25 kg/ha of N + 20 kg/ha P, 6 tons/ha FYM, 50 kg/haN + 40 kg/ha P, 4 tons/ha FYM, 75...

Effect of fire on flowering of Hyparrhenia hirta (L.) Stapf (C4), Merxmuellera disticha (Nees) Conert (C3) and Themeda triandra Forsskal (C4) on the Signal Hill, Cape Town, South Africa

Flowering in Merxmuellera disticha was more strongly stimulated by fire in summer. Flowering tillers produced between 9 and 11 months after fire were significantly more abundant than those produced 21 to 24 months thereafter. Growth in terms of size of individuals was considered insignificant for analysis. NeighboredHyparrhenia hirta showed, to a certain degree, an out-of-season growth, production and...

Diallel analysis for pod yield and its components traits in vegetable Indian bean (Dolichous lablab L.)

The nature and magnitude of genetic variance for yield and its component traits were studied in Indian bean using diallel analysis. The estimates of general combining ability (GCA) variance were much higher than specific combining ability (SCA) variance except days to 50% flowering, number of pod per cluster and fiber content; this indicated the importance of both additive as well as non-additive gene effects are...

The effect of correlated climatic factors on the radial growth of eucalypt trees grown in coastal Zululand of South Africa

Understanding the relationship between stem radial growth and climatic conditions in plantation productivity is important to identify the climatic factors that most influence tree growth. This study aims to determine the climatic factors that most influence the stem radial growth of eucalypt trees plantation in the coastal Zululand area of South Africa. Daily stem radius was measured using automated point dendrometers...

Preferences and constraints of maize farmers in the development and adoption of improved varieties in the mid-altitude, sub-humid agro-ecology of Western Ethiopia

Understanding farmers’ production constraints and preferences is important in maize breeding, especially underlying successful adoption of improved varieties and their production packages. This study was conducted to assess the present importance, and productivity constraints of maize in the mid-altitude, sub-humid agro-ecology of Western Ethiopia. Data was collected through a semi-structured questionnaire and...

Reaction of some of Afghanistan’s wheat varieties to yellow rust under natural conditions

Afghanistan grows wheat at about 2.5 million ha, about 45% of which is irrigated. The country is not wheat sufficient and has been importing to meet domestic needs. Yellow rust is the most important disease of wheat in Afghanistan. Country has been able to manage wheat rusts mainly by having a survey surveillance system in place and by releasing resistant varieties. A total of 30 wheat varieties released during last two...

Crambe seeds quality during storage in several conditions

Crambe abyssinica seeds are spherical and surrounded by a structure called the pericarp. The basic function of the pericarp is to protect the grains against abrasion and shocks, to function as a barrier against microorganisms and to allow the seeds to be stored for long periods of time. The aim of this study was to evaluate the C. abyssinica seed quality stored under different environmental conditions...

Morphological characterization in onion (Allium cepa L.) for preparation and implementation of plant variety protection (PVP) legislation and distinctness, uniformity and stability (DUS) testing under temperate conditions of Kashmir

The objective of this study was to analyze the variation in morphological characteristics of 30 varieties of onion for use as genetic markers. Identification keys for characterizing 30 onion varieties were employed on plant morphology and marked differences were observed among the varieties so that the new onion varieties could be identified, released and patented on the basis of the key. Morphological traits are thus...
