Evaluation of a different fertilisation in technology of corn for silage, sugar beet and meadow grasses production and their impact on the environment in Poland

The most significant and irreversible is the overexploitation of the environment, which is constantly exposed to various forms of pollution. Soil pollution is the result of excessive use of fertilizer in a limited area for growing. Total of 30 technologies were analysed, specifying the pollution degree from fertilizers and natural manure. Technologies concerned three crops: corn for silage, sugar beet and meadow...

Enhancing the growth and yield of pigeon pea through growth promoters and organic mulching- A review

Pigeon pea, a widely spaced row crop having initial slow growth is sensitive to weed competition during early stages of its growth period. A large proportion of uncovered land during early stages is taken over by rank weed growth, which may cause drastic reduction in growth and yield of pigeon pea. Pigeon pea with additional canopy may suppress weeds, due to shade. To accomplish the same, foliar application of micro...

Influence of soil moisture levels and packaging on postharvest qualities of tomato (Solanum lycopersicum)

Preharvest factors influence postharvest quality of tomatoes. Whereas water stress improves fruit total soluble solids; and polyethylene is used for packaging of fresh horticultural produce, little is known about their combined effects on quality and shelf life of tomatoes. The objective of this study was to investigate the independent and interactive effects of deficit irrigation and packaging on postharvest quality...

Difference in germination rate of Baobab (Adansonia digitata L.) provenances contrasting in their seed morphometrics when pretreated with concentrated sulfuric acid

Baobab (Adansonia digitata L.) is considered an under-utilized species even though it is an economically useful tree often used daily in the diet of rural communities in West Africa. Baobab seeds do not germinate immediately after they are released from ripe fruits due to dormancy imposed by hard seed coats. A study was carried out to assess (1) best soaking duration for seed pretreatment in concentrated sulfuric acid...

Prediction of somatic growth of tropical fish using a simple mathematical formula

Age determination or growth rate of fishes is a critical component of a proper fishery management. Current methods of fish age determination or growth rate have several drawbacks, including, large numbers of fish needed over time for analyses, subjective interpretations during age determination or the use of expensive instrument for analysis. In this report, a simple theoretically derived mathematical formula is...
