Description

Evaluation of Spring Maize Hybrids under Irrigated Conditions is a well-researched topic, it is to be used as a guide or framework for your Academic Research.

Abstract

An investigation entitled “Evaluation of spring maize hybrids under irrigated conditions” was conducted at the instructional farm of Krishi Vigyan Kendra Langroya to check the yield potential of three maize hybrids during spring 2018 season. The experiment was laid out in randomized complete block design (RCBD) with six replications. All the crop management practices were followed as per the recommendations of Punjab Agricultural University, Ludhiana. The statistical analysis of data revealed that all the hybrids were non-significantly different with respect to maize cob weight, cob weight, grain: cob ratio, cob length, cob girth at base, middle and top. Numerically, P1844 resulted in highest value of maize cob weight, cob weight, grain: cob ratio, cob length, cob girth at base, middle and top in comparison to PMH 10 and DKC 9108. Maize hybrid P 1844 had significantly higher number of rows per cob (17.50) as compared to PMH 10 (14.67) but statistically at par with DKC 9108 (16.33). Other yield attributes viz., shelling percentage, 100-seed
weight was found to be non-significantly different. The significantly higher grain yield was recorded in P 1844 hybrid (85.46 q/ha) followed by DKC 9108 (69.55 q/ha) and PMH 10 (68.71 q/ha).

Introduction

In Punjab, maize crop is cultivated on an area
of 1.16 lakh ha with production and
productivity of 4.45 lakh tonne and 38.35
q/ha, respectively whereas in SBS Nagar
district, it was cultivated on an area of 7,700
ha with production and productivity of 33,000
MT and 42.39 q/ha, respectively (Anon,
2018). Various biotic and abiotic factors affect
the realization of better grain yield directly or
indirectly. To tackle with these factors,
agronomic and breeding approaches play a
pivotal role. Breeding approach relies upon
the development of superior cultivars which
can perform better relative to existing ones.
Both public and private sectors have done
consistent work in the development of maize
hybrids viz., PMH 10 of Punjab Agricultural
University, Ludhiana; DKC 9108 of Monsanto
seeds and P 1844 of Du Pont Pioneer. The
performance of a particular hybrid/cultivar
varies from one area to another which can be
attributed to variation in the soil
characteristics, existing weather conditions;
availability of irrigation facilities etc. Sharma
et al., (2014) studied performance of different
maize hybrids sown by the farmers in the
Kapurthala district of Punjab and reported that
the grain yield obtained varied between 70.0 to 100.8 q/ha. Similarly, Manan et al., (2016) reported that the farmers were using fertilizers
and pesticides without taking in to account
recommendations made by different research
institutes which has reduced the margin of
profit day by day.

Keeping in view the above mentioned factors,
an investigation was undertaken to evaluate
the performance of three hybrids viz., PMH
10, DKC 9108 and P 1844 under the
irrigated conditions so that the farmers of the
area can be guided properly.
