Effect of row spacing with different levels of phosphorous and biofertilizer on growth and yield of maize (Zea mays L.)

Abstract

A field experiment was conducted at Crop Research Farm (CRF), SHUATS, Allahabad, during the kharif season of 2017 with 12 treatments replicated thrice in randomized block design, to determine the effect of row spacing with different levels of Phosphorous and biofertilizer on growth and yield of maize (Zea mays L.). This treatment consisted of two treatment of planting geometry 60 cm x 20 cm, 45 cm x 20 cm, three different levels of phosphorous 60 kg/ha, 80 kg/ha and 100 kg/ha. Seed was inoculated and uninoculated with PSB. The results revealed that spacing of 60 cm x 20 cm and 80 kg P ha -1 with phosphate solubilising bacteria was found to be the best treatment for obtaining higher grain yield (5.22 t ha -1 ), harvest index (43.13%), test weight (28.33 g) and other growth and yield attributes like higher net returns (Rs 40,303.50/-ha -1 ) and B:C ratio (2.18) was also observed. However, seed inoculation with PSB showed positive differences in effecting the grain yield.

Effect of Different Spacing and Nutrient Management on Growth and Yield of Maize: A Review

“…[13] Rina et. al., [8] reported that the combination treatment of spacing 60 x 20 cm with 80 kg/ha P on PSB treated seeds obtained the best results with higher results namely in grain yield (5.22 ton/ha), harvest index (43.13%) and test weight (28.33 g). According to these findings it may be considered that offering strategies of spacing and nutrient management techniques like using of biofertilizers may improve the maize production system giving a major emphasis in sustainable agriculture.…”

“…al. [8] using a spacing half the size they have experimented, Paul [10] concluded that using spacing distance of 35cm x 10cm gives the maximum production of green fodder. Sharifi and Namvar [11] found that the significantly taller plants, total dry matter was found in intra row spacing of 45cm.…”

“…In the same year, Rina et. al., [8] found that providing a spacing of 60 x 20 cm gives better values in terms of growth and yield attributes like harvest index, test weight, etc. Similarly, Mahato et.…”
