“…This was also reported by Nagdy et al (1979) who ob- Ekwu and Nwokwu (2012). Even though plants in low population densities, had higher values in most vegetative characters, which had been reported to have higher correlation with number of fruits and fruit yield (Ngozi, 2013), their cumulative yield were low based on lower plant population. The higher population densities due to competition for space and assimilate could not produce fruits as those with low population in both number and weight on single plant stand basis but on cumulative basis higher populations produced more number of fruits.…”

An experiment was conducted in the Experimental Farm Garden, at Assam Agricultural University, Jorhat to see the influence of crop geometry and spacing of Long pepper (Piper longum). Result showed that the plants grown with support crop geometry of 60 x 40 cm yielded maximum (516.59 kg/ha Dry), which was significantly higher than the crop grown without support. The other yield attributing parameters also found superior in the above method growing with support and plant geometry. But the B.C ratio is better in the case of without support method in crop geometry 60x40cm (1.89 ) compared to with support, i.e. 1.84

“…This also related to the overall issue of plant density and therefore seeding rate and seed placement. Optimum planting depends on its effect on seed yield and quality in many crops (Ogbonna et al, 2015;da Silva et al, 2016;Abu and Odo, 2017;Ngozi and Chidera 2017). Row planting has an advantage particularly with tussock grasses, such as Panicum, Andropogon, Pennisetum and Setaria species and seed production of Cenchrus spp.…”

The poor seed yield from some pasture grasses may result from a number of causes, such as the choice of site production, low soil fertility, inappropriate sowing rate, inadequate crop management practices particularly plant density, fertilizer input, poor seed recovery, etc. Compared with sowings of general plant use, seed crops warrant more care and expense during the establishment phase. Seedbeds should be prepared more thoroughly and the seed sown more precisely using adequate seeding rates. The effect of row spacing on the one hand and nitrogen level application on the other hand, have variable effect on grass seed production and there are a conflicting report in some cases depending on species, management practices and environmental conditions, and therefore a case-by-case study for each species and environment is important. In general, seed growers had better to sown seed in row than broadcasting and row spacing of 50-80 cm can be recommended for seed production depending on grass species or cultivars. The selection of optimal production areas depends on soil fertility, the photoperiod and temperature which can interact with rainfall and humidity of the site. The optimum sowing depths was 0-30 mm with some species and cultivars emerging from greater depths than others. With some exceptions, larger seeds were generally able to germinate successfully from greater depths. It was reported that seeds of Brachiaria brizantha and Panicum maximum established better when covered by 20-50 mm. Generally, applying fertilizer nitrogen to seed crops has implications for yield component dynamics such as tiller increasing, number of fertile tillers, floret per spikelet, and seed per head and ultimately increases seed yield and quality. Amounts of nitrogen fertilizer required will depend on species, soil type and rainfall. More often, 100-250 kg of nitrogen per ha and crop and rate more than 300 kg N/ha caused reduction in seed yield by severe plant lodging. For optimum time for nitrogen application, it can be recommended to growers to apply nitrogen in the period from vegetative to spikelet initiation.

“…Since the plants with wider canopy were not the same treatments with higher fruits, plants with smaller canopy diameters will allow smaller spacing, placing a greater number of plants per unit area, this will favour better use of the cropping area and increased yield. Moreover, no significant dosage effect was observed on canopy diameter; therefore, the yield is more dependent on the population density as reported by Abu and Odo [30].…”

This study was aimed at inducing mutation on three cultivars of Capsicum annuum L. to source for new and favourable genetic variations that could be exploited for better agronomic traits. The mutation was induced by exposing the seeds of Shombo, Tatase and Nsukka yellow pepper to varied dosages (0, 50, 100, 150 and 200 Gy from 60Co source) of gamma irradiation. The study was conducted in the Botanic Garden of the University of Nigeria. Seeds exposed to 50Gy produced significantly (P < 0.05) the highest number of fruits per plant, highest fruit yield and improved morphological traits in Shombo. Higher dosages of irradiation gave lower fruits per plant and yields than untreated seeds in Shombo. Tatase irradiated with 150 Gy had significantly the highest single fresh fruit weight. Generally in Tatase 50, 100 and 150Gy increased some morphological traits significantly (P < 0.05). Although 50 Gy gave highest number of fruits per plant, 100, 150 and 200Gy had significantly higher fruit yield with yield increasing as dosage increased. For Nsukka yellow, irradiation did not show a consistent pattern in improving morphological traits. But 200Gy produced significantly the highest number of fruits per plant and highest yield. Gamma irradiation dosage of 50 – 200 Gy can be exploited to create variability for improvement of morphological and yield traits in pepper plants.
