In the present investigation the seeds of Pigeon pea (Cajanus cajan (L.) Millsp) were treated with different doses of gamma radiation (05KR, 10KR, 15KR, 20KR, 25KR, 30KR, 35KR, 40KR, 45KR, and 50KR) and concentration of Ethyl Methane Sulphonate (05mM, 10mM, 15mM, 20mM, 25mM, 30mM, 35mM, 40mM, 45mM, and 50mM) for studying seed germination, seedling height, (shoot and root), seedling injury, seedling vigour index, and seedling survival of plants at 30th day. The seed germination percentage was decreased with increased in the concentration/doses when compared to control. The LD50 (Lethal dose) value was determined based upon the seed germination percentage. The 50 percentage of seed germination and reduction was observed in 20KR of gamma rays and 25mM of EMS and it is considered as LD50 value for both the treatments. The decrease in seed germination was more prominent with gamma rays than that of EMS treatments. The seedling parameters of gamma rays and EMS treated seedlings were progressively decreased with increase dose/concentration in all mutagenic treatments when compared to control. The maximum seedling parameters were observed in 05KR of gamma rays and 05mM of EMS. Minimum seedling parameters were observed in 50mM of EMS and 50KR of gamma rays respectively.

Seed quality at physiological and harvest maturity of two pigeon pea cultivars viz. AL15 and T21 was compared. Seeds of both cultivars attained maximum dry weights, germination potential and seed vigor in terms of root/shoot lengths and dry weights of seedlings at 35 DAA in cv AL15 and 46 DAA in cv T21 denoting their physiological maturities. The levels of endogenous seed reserves like starch, proteins, lipids, DINA and RNA were comparable at physiological and harvest maturities. The seeds at physiological maturities i.e. at 35 DAA in cv AL15 and 46 DAA in cv T21 attained most of the required characters associated with the harvest of crop.

The study focused on the profitability of pigeon pea production in Riyom LGA of Plateau State. Data for the study were obtained from both primary and secondary sources. Questionnaires were administered to 80 targeted farmers to get information on their socio-economic characteristics, years of experience in pigeon pea production and the reason for growing pigeon pea. The analytical tool used includes descriptive statistics to analyze the socio-economic characteristics of the farmers and farm budgeting technique (gross margin analysis) for assessing the profitability of pigeon pea production. The study also identified the constraints encountered by farmers such as high cost of labour, inadequate processing / storage facilities, problems of access to credit/loans and weed/pest infestation. The results shows that pigeon pea production is profitable with a total variable cost (TVC) at N22620.68 per ha, while gross revenue (GR) was N50185.25 per ha, the profit margin (GM) at N32564.59 and the net return per Naira invested was N0.69. It was recommended that farm inputs and improved seed varieties should be made available to farmers at affordable rates so as to enable them operate at a commercial and profitable level of pigeon pea production. These farmers should be encouraged to form a cooperative society so as to alleviate the problem of credit/ loan acquisition and procurement of genuine products as well as avoid exploitation.

Drought poses one of the most important environmental constraints to plant survival and productivity and by implication-food insecurity in the tropics. Pigeon pea (Cajanus cajan) has the potential of fertilizing the soil thereby improving agricultural production and ensure green environmental and ecosystem stability. Despite the ability of the plant to improve soil fertility and promote greening environment, it has not attracted adequate awareness as a soil improvement plant. This paper highlights the information on the plant in order to intensify awareness for its widespread adoption to achieve the much desired sustainable resource use for greening our economy and environmental management. The successful widespread adoption of the plant will translate to effective drought, desertification and sustainable climate change mitigation approach in Nigeria.
