ABSTRACT: Background:Pigeon pea (Cajanus cajan L. Millspaugh) is an important legume known for its nutritional value. Pigeon pea is a minor crop, but it plays a key role in the subsistence of smallholders in West African countries such as Nigeria and Ghana. Pigeon pea research in terms of mutational breeding in Nigeria is still at a low level compared to other leguminous crops such as cowpea. Despite the numerous uses and nutritional values of pigeon pea, the plant has received little mutagenic research attention, hence, the need for this study. Materials and Methods:Uniform and healthy seeds of the pigeon pea accessions were selected and pre-soaked in distilled water for 6 hours. The pre-soaked seeds were soaked in freshly prepared EMS concentrations (0.0 %, 0.01 %, 0.02 %, 0.03 %........

ABSTRACT: Soilborne diseases are of difficult control in organic horticultural production. We studied the effect of organic amendments combined with solarization to control pink root of onion, caused by Phoma terrestris, as a model pathosystem. Two field trials were carried out on a sandy soil, previously infested experimentally with S. terrestris. The amendments incorporated into the upper 10 cm of the soil were: green residues of Brassicaceae species, fruits of Persian lilac (PLF) (Melia azedarach) and fresh chicken manure. One half of the experimental units were covered with a transparent polyethylene film, during 25 days in late spring (november-december). There were three replicates. Mean soil.......

ABSTRACT: Background: Wheat is among the most important crop in the world and its consumption in Niger is increasing rapidly, but the national production in the country is very low due to lack of knowledge on cultivation techniques. Adequate Nitrogen and irrigation management practices as well as choice of good variety can significantly increase yield. Materials and Methods: A field experiment was conducted during two dry seasons (2016/2017 and 2017/2018) at Konni in central southern zone of Niger Republic. Analysis of variance and acorrelation analysis were performed between some yield characters of four wheat varieties (El-Madaoua as local check, Sokoll/3/, Norman and Reyna-28) and a regression analysisto explain the variation of grain yield response under four different doses of nitrogen (0, 100, 150 and 200 kg N ha-1) was done. The experiment was laid out in a split plot design with three replications........

ABSTRACT: Fluted pumpkin is one of the popular cut vegetable grown in southern part of Nigeria. However, it is an underutilized indigenous vegetable in Southwestern Nigeria due to limited data on its production and economic importance. This study which was on Effects of Seasonal Variation and Fertilizer on Yield and Yield Components of Fluted Pumpkin(Telfairia occidentalis)was carried out at the Teaching and Research Farm of the Obafemi Awolowo University, Ile-Ife. The study was in two phases. The first phase was under rainfed while the second phase was carried out under irrigation. The physico-chemical properties of the soil in the study area such as pH, electrical conductivity, bulk density, available Phosphorus and exchangeable cations at three different depths (0-10 cm, 10-20 cm and 20-30 cm) were determined using standard procedures........

ABSTRACT: The paper analyzed small-scale rice production in Nigeria. Primary data were collected using well-structured questionnaire for the study. Multi-stage random sampling technique was used to collected data from three hundred and forty-nine (320) rice farmers used for the study. Total productivity index, resource-use efficiency index and principal component analysis (PCA) were used to analyzed the data. The result of the total productivity index revealed that majority of the farmers (62.18%) were sub-optimal (<1.00). The result of resource-use efficiency further revealed that farm size (0.19), fertilizers (0.43), agrochemicals (0.37), seeds (0.69) were over-utilized, while labour (1.64) was under-utilized. This implies sub-optimal allocation of production resources by rice farmers in the study area........
