“…However, no-till soybean yield responses to K fertilization were rarely significant with optimum to high K content soils (Borges and Mallarino, 2000). The enhancement of yield characters and yield might be due to the influence of adequate nutrients, helped the crop to perform better with growth and ultimately the yield (Rajesh et al, 2017) and split application of nitrogen is a better option to harness high seed productivity and to maintain soil fertility (Sharma et al, 2017).…”

A field experiment was performed to evaluate the effects of tillage systems and fertilizer management on the growth and nutrient uptake in soybean. The plant height, fresh weight and dry weight of conventional tillage (CT) were much higher those observed for no-tillage (NT). The highest plant height (128.47 cm) was observed in CT with chemical fertilizer. The plant nitrate concentration was higher (2.29%) in NT with green manure than chemical fertilization. However, nitrogen increased steadily in all treatments, and the highest quantity of total nitrogen (476.7 Kg/ha) was observed in NT with green manure. The NO 3 -N content in the soil decreased gradually just after the vegetative stage. Tillage practices and additional fertilizer application was less effective on the uptake of N, P and K in soybean seeds as compared to NT with green manure. The results postulated that NT strategies with fertilizers might influence the growth characteristics and mineral uptake in soybean.

“…As there is an emerging demand for dhaincha seeds, efficient agronomical interventions are required to ensure the seed quality and storage. Few researchers have attempted to study the effect of spacing, fertilizer level and different nutrient management practices on seed yield of dhaincha (Rajesh et al, 2017 andGopal et al, 2016). But Among the different seed production practices, harvesting and threshing are very much important operations as it has many impacts on post-harvest seed quality and viability.…”

Background: The present investigation is an attempt to study the effect of different harvesting and threshing methods on germination and seedling vigour of dhaincha. The use of a combine harvester to harvest dhaincha will be an effective alternative method that has not been widely tried. However, work on different methods of harvesting and threshing of dhaincha is limited. Hence, a study was conducted to evaluate the impact of various harvesting and threshing methods on germination and seedling vigour of dhaincha. Methods: This study was conducted at Anbil Dharmalingam Agricultural College and Research Institute, TNAU, Tiruchirappalli, Tamil Nadu. The dhaincha crop was harvested and threshed using four different methods viz., manual harvesting and manual threshing, manual harvesting and threshing by tractor treading, manual harvesting and mechanical threshing and harvesting and threshing by combine harvester. The resultant seeds were tested for mechanical damage and germination potential. The experiment was laid in completely randomized block design. Germination was tested by roll towel method using 100 seeds in four replications. Germination percentage, root and shoot length were measured in seven days after sowing from ten randomly selected seedlings in each replication. For the estimation of dry matter production, ten seedlings were selected at random and kept in a hot air oven maintained at 85oC for 24 hours after measuring their root and shoot length and vigour index was calculated. Mechanical damage to seeds was observed by ferric chloride test. Seed recovery per cent was calculated based on the 100 kgs of dhaincha seeds were cleaned and graded treatment wise using cleaner cum grader and the seeds retained on the bottom sieve were weighed and expressed as per cent of total quantity of seed. Result: The results revealed that the significant difference was found among the different harvesting and threshing methods. The seeds harvested and threshed by manual method recorded 85 per cent germination followed by seeds harvested manually and threshed by mechanical threshing (84 per cent) and seeds harvested manually and threshed by tractor treading (80.5 per cent). The lowest germination of 80.0 per cent was recorded by combine harvesting. From this study, it could be inferred that combine harvester is a modern method for harvesting of dhaincha that saves time and labour when compared to all other methods.

“…It has been reported that individual plant performances especially morphological growth characters reduce when there is an increase in plant density (Galanopoulou-Sendouka et al 1980) while wider spacing will cause more sunlight to be intercepted for photosynthesis, which leads to the production of more nutrients for partitioning for the development of more branches (Mehmet, 2008). Maximum light interception is possible when optimum plant space is provided right from early growth stage of the plant (Rajesh, et al, 2017). Total biomass production of a crop, with assumption of no water limitations, is the product of solar radiation received by the canopy of crop over the duration of the cropping period and the rate of efficiency by which the crop converts energy from light into plant dry matter (Richards, 2000).…”

The study was conducted to evaluate the effect of incorporated lablab planted at various spacings on productivity of two maize (Zea mays L.) varieties in northern Guinea Savanna zone of Nigeria. Field experiment was carried out at the Research Farm of the Institute for Agricultural Research, Ahmadu Bello University, Zaria, Nigeria. The treatments consisted of two varieties of maize (SAMMAZ 28 and SAMMAZ 29) and six green manure lablab (Lablab purpureus) plant spacings viz. 25cm x 10cm, 25cm x 20cm, 25cm x 30cm, 50cm x 10cm, 50cm x 20cm and 50cm x 30cm. The experiment was laid out in a Randomized Complete Block Design (RCBD) in factorial arrangement and was replicated three times. SAMMAZ 29 performed significantly (P<0.05) better than SAMMAZ 28 on growth, yield components and grain yield (kg ha-1) of maize. Incorporation of lablab planted at various spacing significantly increased grain yield (kg ha-1) and all the maize parameters studied except cob diameter. In combined mean, incorporation of lablab planted at 25cm x 30cm significantly increased grain yield but at par with incorporation of lablab planted at spacing 50cm x 30cm. In combined mean, incorporation of lablab planted at 25cm x 30cm gave 18.2, 20.5, 18, 28.6 and 13.6% better grain yield than incorporation of lablab planted at spacings 25cm x 10cm, 25cm x 20cm, 50cm x10cm, 50cm x 20cm and 50cm x 30cm, respectively. Conclusively, incorporation of lablab planted at 25cm x 30cm was better than other spacings on SAMMAZ 29.
