Uniform description of developmental stages in crops improve communication among producers, researchers and others. A standardized, accurate, and easy system is needed to describe bean (Phaseolus vulgaris L.) plant development. The objective of this study was to develop and describe stages of bean plant development in a manner which is simple but accurate. The biological cycle of the bean plant is divided into two successive phases: the vegetative stage (V) and the reproductive stage (R). Vegetative stages are determined by counting the number of trifoliolate leaves (V1 to VN) on the main stem beginning above the unifoliate leaf. Reproductive stages R1 and R2 are based on flowering, R3 and R4 on pod development, R5 and R6 on seed development, and R7, R8 and R9 on maturation.

The aim of the study is to determine the seed quality of different dry bean genotypes, grown under full and limited irrigation conditions. The study was conducted at Nigde Omer Halisdemir University laboratories. Eight different dry bean cultivars (Yunus 90, Cihan, Goynuk 98, Batalla, Alberto, Arslan, Zirve, Noyanbey 98) were used in the study. The study was established with 3 replications according to randomized split-plot design. Quality characters like dry and wet seed weight, water uptake capacity, water uptake index, dry and wet volume, swelling capacity and swelling index, cooking time and protein content were determined. In conclusion, statistically significant differences among applications and cultivars were observed in terms of the all parameters examined. The grains obtained from the limited irrigation plots, had lower values in terms of all evaluated properties. Differences between dry and wet weight, water uptake capacity and index, dry and wet volume, cooking time and protein content between cultivars were statistically significant. In the study, correlation between cooking time and grain size was determined, and it was concluded that enlarging in grains size increases the cooking time. In addition, it was concluded that limited irrigation in the reproductive period had a negative effect on seed quality of different dry bean cultivars and it should not be lowered below 50% of the water capacity in the soil during this period.

Drought is one of the most harmful abiotic stresses affecting the development and yield of the common bean (Phaseolus vulgaris L.). The current climate change and the resulting increased drought will worsen the negative impact of water stress on the plant. The powder of orange peel and cauliflower waste were added as soil supplementation at rates of 7 and 15 g/pot to pots of Phaseolus vulgaris L. under different drought conditions. The growth and physiological analysis were estimated after flowering period of common bean. In the pots where drought will be applied, irrigation was stopped for 2, 4, 6, 8 and 10 days during the flowering period and irrigation was performed again after water stress application. To measure moisture percentage of pots, first dry pots were weighed and after irrigation, their moisture variation in terms of percent was measured during stress from 2 to 10 days. The highest plant height was obtained from control. Leaf area decreased significantly despite the application of different powder, especially after 4 days of drought conditions. The highest root fresh and dry weight, raw ash were observed under control with the application of 7.5 g orange peel powder. Shoot dry weight decreased as the number of days exposed to drought increased, and the application of 15 g orange peel and cauliflower powder gave the highest results compared to control conditions. The highest dry matter was obtained from the application of 7.5 g and 15 cauliflower powder in the absence of drought. It has been revealed that as the duration of exposure to drought increases, the value decreases and plant powders are effective in increasing this value. Chlorophyll a, chlorophyll b and total chlorophyll values decreased significantly with drought, and the highest value was obtained from control conditions, followed by 15 cauliflower powder applications.
